Description

The invention relates to a protective wall, in particular flood protection wall, with posts used in stationary shots, which have running in the plane of the protective wall grooves and insertable between the post in the grooves plate elements, wherein the plate elements in a sunk in the ground stationary and in cross-section U -shaped trough are arranged and the plate elements, preferably via a pulling device hochziehbar and connectable to a substantially dense wall.

The Patent Abstracts of Japan to JP Publication Number 2003082956 discloses a watertight bulkhead comprising individual, interconnected panel elements which are arranged in a fixed U-shaped fixed sunken trough in the bottom and which can be pulled up as needed in a Venetian blind.

The JP abstract to publication number 2004044284 discloses a protective wall with vertically arranged posts with grooves in which individual plate-shaped elements are inserted one above the other.

A removable flood protection wall is for example from the DE 195 12 544 C1 known. This flood protection wall is intended to provide adequate protection for flood-prone areas, which can not be protected, for example, by permanently installed protective systems such as dykes or the like. Such flood barriers are to be mounted at a high water level, which exceeds a critical mark on appropriately provided foundations.

River straightening, especially in the form of canalization of rivers, the degradation of floodplains, but also unpredictable storms or oversized snow melts lead for more than 20 years to high water levels caused by existing dikes or embankment walls can no longer be intercepted. However, the times when there is an acute risk of flooding, relatively rare, so that permanently remaining on-site buildings are undesirable, especially in the times when the river has a normal water level, especially in cities are considered visually disturbing. Already for this reason, portable flood protection walls have been proposed at an early stage, which can be quickly erected in case of need and later dismantled again. So will in the DE 84 01 849 U1 proposed a portable wall, which consists of a plurality of spaced-apart uprights for sealing attachment of projecting into a gutter wall parts. The stands are to be formed by a straight 1-profile piece and placed vertically in the bottom groove having a rectangular cross-section. The attached to the uprights wall parts abut a vertical wall of the gutter, with between the wall parts and the other vertical wall of the gutter tendons are arranged.

From the DE 34 48 322 C2 and the DE 34 29 190 C2 Flood protection walls are known, which can be set up by means of posts on a foundation embedded in the ground as needed. The posts are anchored at regular intervals in a foundation associated with the clamping device. Between two adjacent posts then a protective wall section is used, however, disadvantageously has large dimensions and a high weight.

Board-like insulating elements, which are inserted in post grooves from above, are from the DE 91 13 405 known. With the from the DE 195 12 544 C2 known curved plate elements which are curved so that they are pressed sealingly into the grooves with the rising water pressure of the flood, and having an upper and lower edge portion, wherein the associated wall sections of two superimposed plate elements sealingly interlock, the handling of the plate elements as well as the tightness at higher water pressure can be improved.

However, the mobile protective walls described in the aforementioned documents have the disadvantage that respective wall parts must be stored in a warehouse or other location that is not installation site for the wall, and if necessary be brought to the spot where they are to be mounted.

In contrast, is arranged stationary, for example, in the DE 196 51 389 A1 described device having a connected at least to the shore protective wall, on the front side a floating body is fixed, wherein the protective wall is pivotally articulated by means of a pivot bearing on the bank, so that this protective wall rests on the shore at low water and in the course of an increase of the Water level automatically swings up while raising the float to the shore side. However, such devices are not completely maintenance-free, since it must always be ensured that all pivot bearings are equal On the other hand, it must be ensured that the floats remain attached to the intended lower edges of the swing wall.

In the DE 299 16 355 U1 It is proposed to design the hinged wall from the horizontal to a vertical position by means of hydraulic cylinders pivotable. However, such hydraulic cylinders or other mechanical swivel devices also require intensive maintenance.

Another type of flood protection devices is used for example in the DE 102 01 882 A1 described. This device has at least one arranged in the bottom floodable container in which a number of floats is arranged, on which lifting walls are supported, which float in the rise of the water level in the container and move the lifting walls out of the container. The lifting walls should consist of laminated wood and be connected via a hinge connection with the respective floating body, which also consists at least partially of laminated wood, so that the float and the laminated wood wall collectively take over the lifting function.

However, such floats can tilt slightly, so that under certain circumstances, a floating is blocked. In addition, by means of such floats only in length very limited water protection walls can be built.

In addition to the floating parts and hydraulically actuated flood protection walls, z. B. in the DE 201 14 717 U1 been proposed.

The construction of anti-flood barriers is still an urgent need, taking into account the wishes of the public that, after the flood has subsided, that H. at the level normal, should not disturb the cityscape or landscape.

With regard to possible short warning times should also be ensured that the barrier can be constructed quickly and reliable. Of the Disadvantage that have mobile protective walls, which are composed of parts that are stored away from the place of need, and where there is a risk that essential parts are lost during storage or transport and that their lack of a safe construction of the protective wall not more is guaranteed, should be avoided. In addition, the assignment of individual components is sometimes difficult, which can also lead to parts are misguided and are not available in time during assembly.

Also outside flood protection there is a need for protective walls, for example, to create a temporary protection system and or privacy protection for extreme stress situations, which also fireproof, burglar-resistant, explosive (where the wall absorbs the energy of an explosion wave), fire suppression, against debris, impact and / or can be configured as a first protective wall. Corresponding walls can be used to protect buildings which, due to their exposed position, have to be protected as a result of terrorism, sabotage or other motives (nuclear power plants, large computer centers, banks, embassies, public buildings) and which serve as personal protection.
The object and personal protection walls known from the prior art often have a high weight and can be brought in and installed as mobile walls only with great effort.

It is an object of the present invention to provide a protective wall of the type mentioned, which can be erected quickly and safely when needed, is easy to handle and has the necessary reliability as resistance in particular under the action of external forces. Furthermore, the protective wall should be inexpensive and at least largely maintenance-free.

This object is achieved by the protective wall according to claim 1.

According to the invention, the posts of the protective wall are horizontally mounted in a U-shaped, recessed in the floor stationary trough and in a vertical Position swiveling. In the same tub, a plurality of plate elements are further arranged, which, preferably via a pulling device, are hochziehbar and connectable to a substantially dense wall.

By the U-shaped trough advantageously an optimal anchoring for the (main) post as the main carrier of the protective wall is created. The tub also serves as a storage location for the posts, which are erected if necessary by pivoting, after which the also arranged in the tub plate elements are mounted between the posts. By this measure, a transport of individual components for the protective wall and storage at another location is saved. The confusion of parts or their absence are excluded. The protective wall can also be erected as quickly as possible without great personnel expenditure to a stable structure that can be dismantled just as quickly after use again.

Further developments of the invention are described in the subclaims.

Thus, according to one embodiment of the invention, the plate elements are intended to be interconnected lamellar bodies, which are preferably designed as angle profiles. In principle, recourse can be made to profile designs which are used in blinds or Venetian blinds, but the dimensioning of the profiles and their design must withstand the maximum hydrostatic pressure resulting from the overall height of the protective wall. In the simplest version, the individual slats can be inserted into existing grooves of the posts and stacked on top of each other to the desired or provided protective height can be constructed. Preferably, however, the lamellar bodies are connected together and by means of a pulling device, for. B. a motor-driven winch.

According to a further embodiment of the invention, the plate element by means of clamps, bars or other closure and / or clamping means and / or by means of a clamping belt of a rope or a chain which vertically is clamped, pressed together in the assembled state. Clamps such as a clamping belt serve as means which allow a secure blocking and bracing of the protective wall elements - here the plate elements.

In order to facilitate the erection of the post or each post in the vertical position, the post has one or more built-in springs or gas springs, the restoring force supports the raising from the horizontal to the vertical. This may be one or more torsion springs, torsion springs, gas springs, coil spring and or other Aufrichthilfen, which are arranged in the lower post area and / or in a holder of the tub.

Also for increasing the stability serve on or in the post arranged support arms, which are swung laterally, wherein the first end rests in the pivoted state on a preferably flat, horizontal abutment and / or a receptacle. The support arm may preferably be secured with a transverse arm which engages in particular at the lower end of the support arm, wherein the other end of the transverse arm can be locked in the post, with this measure, the posts are additionally secured against the pending on the other side pressure.

To secure also strong retaining bolts with pipe in the lower area and locking bolts in the upper area, which are guided in corresponding holes and lock the post. In principle, it is advisable to design the post such that the post lock can be accomplished independently of the pivoting of the post about a horizontal bearing. In particular, it is recommended that the post after reaching the vertical position by the lower retaining bolts with pipe and the one or more springs z. B. gas springs is held, which effectively blocks a back swinging. Locking screws on the locking unit and / or on the locking bolt above prevent the willful dismantling of the protective wall.

In order to build two adjacent walls in an angular position to each other, is provided for further development of the invention that at least part of the posts is designed as corner posts and at a predetermined angle (<90 °, preferably 30 ° or 45 °) pivotable post wall parts has, created by pivoting gaps can be filled by other swinging post wall parts, all pivotable and swing-out post parts by screws and / or bolts in the final position can be secured. This corner post lowers and / or arises in the vertical in a corresponding to the predetermined angle formed corner U-shaped tub. As will be taught later, such pivoted post parts serve as mounting locations for plate elements.

For further support of the plate elements and for their stabilization may also be advantageously provided to provide the swivels on the post swung-length flaps.

In particular, in the cases in which the protective walls are to serve as a barrier wall, the massive, extreme load situations and impacts must resist, such. As shocks, a vehicle that attempts to break this protective wall, pressure surge waves, but also to prevent any uncontrolled detachment, debris in any breaking out of individual parts of the protective wall is preferably provided, the posts and / or the plate elements with receptacles for retraction of horizontal steel cables or high-strength straps to provide ropes. These steel cables are also preferably stored in the tray arranged in the bottom. The toothed and wedged wall and plate elements, which are connected with high-strength straps or ropes, prevent uncontrolled detachment.

Additional stabilization measures are also provided by additional posts as rear supports of the plate elements or of the composite created by a plurality of plate elements. These additional posts are preferably stored in the fixed floor pan. It can very quickly several additional posts in one element be used and ensure a higher durability in certain places, such as at corners or places the water flows strong, in flood loads or other prominent points in an object protection wall.

Since the stationary floor pan also serves as a support for the individual posts of the system wall, this tub is solid, preferably made of reinforced concrete, concrete, UHPC concrete or other high-strength materials.

To cover the inner cavity of the stationary trough more pivotable about a horizontal axis end cover are also provided, which terminate flush with the surrounding surface in a horizontal position. Such end covers preferably form with the adjacent surface a flush ceiling, which is walkable and passable by car or truck. Depending on the customer's wishes, different surfaces can be incorporated in the ceiling. The end cover forms a further protection against extreme load situations such as shocks, explosions and protection against debris (boulders and stones). The end cover is folded up, placed in a shot and forms both the lower part of the wall and there a strong protection. These end covers close the storage space for the posts, the plate elements and possibly other center posts and steel cables or high-strength straps or other fasteners such as bolts and / or plates, which are needed for erecting and stabilizing the protective wall.

According to a further embodiment of the invention, the trough adapted to the geographic conditions forms a water channel, so that water flowing in, for example, flows into the trough to the lowest point. At this lowest point, possibly a seepage, a pumping device is preferably arranged.

Attached to the concrete trough cross bar takes over the load transfer from the wall by means of an abutment in which the support arm is used, concrete anchors on the crossbar, recordings for bored piles, recordings for angles and Shooting for sheet pile walls and other structures in the ground. The individual load transfer options can vary differently, so that an optimal load transfer can be ensured in the Tiefgrundsystem.

The concrete tub or tub of high-strength material is laid like a pipe. It eliminates complex measuring work for mounting plates, foundations, basic seals - as are common in known in the prior art mobile walls - because the tub forms a unit with the posts, support arms and plate elements.

Furthermore, a tub has the advantage that the water can not be pressed into the "dry area", for example, by rinsing under groundwater or by groundwater.

In order to facilitate the pulling up of the plate elements, cable winches, hydraulic systems and / or other structural aids is further provided as a pulling device mounted on a post and / or plugged from post to post, and / or vorfahrnen and by means of a motor, and / or as Manual operation are autonomously operable.

Optionally, the plate elements may be arranged on a common mat as a carrier, which is arranged rolled up in the disassembled state of the protective wall in the stationary trough. Similar to a venetian blind, the mat is unrolled, preferably by means of the cable winch described above.

The plate elements may additionally be supported by horizontally or vertically arranged and tensioned safety bars.

The plate elements may also be arranged as plates horizontally or vertically disposed in the tub.

At least the plate elements, but also different posts and / or beams can be made of aluminum for weight reasons. The use of steel, concrete, plastic, UHPC concrete and / or other stable materials as building material, however, has the advantage of increased system stability, the ability to use heavy explosion-resistant materials and to significantly reduce the cost of the protective wall.

The protective wall shown in the figures consists essentially of a plurality of posts 10, which are each arranged to a vertical pivot in a tub 11 made of reinforced concrete or other high-strength materials, in which the plate elements 12, of which in the exemplary drawing five copies are shown to be kept.

The shape design and the function of the individual parts will be apparent from the following description of the various steps that are required for the construction of the protective wall.

Initially, all necessary for the erection of the protective wall components in the tub 11 made of concrete, UHPC concrete and / or other high-strength materials, which is closed by a cover 14 which is also made of concrete and or high-strength material, which is flush with the closure the road surface 13 closes. The concrete tub and / or tub of other high-strength materials forms an optimal anchoring in the ground. By the cross bar 46 as shown in Figures 10 to 12 and attached anchors such. Angle 47 bored piles 48 and sheet piles 49, the pressure loads as load transfer, which can act on the protective wall, optimally dissipated in the Tiefgrundsystem. Similarly, the end cover 14, in conjunction with the pan 11, is capable of withstanding high weights of 30 tons or more that can occur when driving over a truck. The end cover 14 is made day waterproof. The construction according to the invention can be arranged or installed in roadways, footpaths, on boardwalks, on squares or even green areas and consists of UHPC concrete and / or other high-strength materials.

Since in case of flood warning (or in other cases of necessity) all necessary parts for the erection of the protection wall are on site, without long warning times the Protective wall to be built with few people. As can be seen from Fig. 2, for this purpose first the cover 14 is pivoted about a horizontal axis, whereby the parts located in the tub 11 as the additional posts 15, the individual designed as a dam angle plate members 12, the (main) post 10 with holding unit and Anchoring 45 and about required steel cables and / or high-strength straps 17 are exposed. First, center posts 15 and steel cables and / or high strength straps 17 are laid on the road surface. Subsequently, the post 10, which is bolted to the lower end of the holder 45, with one or more springs 18 preferably, for example, gas springs folded up with little effort (see Fig. 3). Subsequently, a tilted support arm 22 is pivoted together with a transverse arm 23 in the position shown in Fig. 3 and 18, in which the lower end of the support arm 22 is supported on a horizontal abutment 16. Here, the support arm 22 is released from an upper and guided down until its upper end is fixed in a lock 25. Finally, a bolt 26 will fix the support arm 22. The end cover 14 is folded in front of the post 10.

Subsequently, and as indicated in Fig. 4, a motor winch and / or other assembly unit 29 is wound on the post 10, plugged, with which the plate members 12 are pulled up. These plate elements 12 are preferably connected to each other via individual bands, ropes, chains and / or high-strength straps 45, so that they do not have to be pulled up individually.

Subsequently, and as shown in FIGS. 2, 3, 4, 18 and 19, the individual plate elements are connected to one another at their horizontally lying sides, for instance according to the tongue and groove principle, to form a dense wall, and the lowermost plate element has a larger nose 53 and clamps on the lid 14, to which serve individual terminals, latches or locking devices 30 as well as a clamping belt or clamping cable 31, which engages over the plate element flaps 38 cooperate.

In order to build the protective wall not only in a vertical plane; but also allow each other at an angle arranged protective wall parts, corner posts of FIG. 15 to 16 can be used. The commonly used post 10 has, as shown in Fig. 14, a 1-cross-sectional profile with flaps 38, which can be pivoted by 90 °, if necessary. A post can serve on both sides 39 and 40 as a retaining wall of protective walls, which lie in a plane. Fig. 15 shows a post which, as shown, may be similarly used as an end post or (after folding down a flap 38) as an intermediate post but having additional swing-away post wall parts 41, 42 which either fold in (see Fig. 15). or are folded out by an angle of about 30 °. The corresponding wall parts 41, 42 are fastened together in the unfolded state with bolts or screws or other fastening units. By using the post 43 shown in FIG. 16, a wall can thus be erected along a tortuous river bed and / or road course.

Further advantages of the protective wall can be summarized as follows: As can be seen from the above explanations, no special expertise is required for assembling and dismantling the wall, so that corresponding work can be carried out by practically anyone. The construction as well as the dismantling can be made for a short time, whereby between two times, in which the protective wall is used, long times can lie, in which without maintenance the protective wall components are kept safe. External storage and transport of mobile elements "on site" are not required.

The construction according to the invention can consist of steel parts, plastics, concrete, UHPC concrete and other high-strength materials, as well as aluminum parts. If lifting and transport work, which must be done by operators, can be saved by using a motor winch with generator with self-sufficient use, can be used for cost reasons exclusively on steel parts or other high-strength materials.

The present protective wall can also be used for physical protection, which is protected and reinforced due to its exposed position as a result of terrorism, sabotage or other motives. If necessary, the protective wall is made of impact-resistant, impact-resistant, explosion-resistant material or non-ballistic additional panels installed in the wall.

Of course, the existing protective wall also provides, if necessary, as shown in Fig. 8 and 9 Aufsatzmöglichkeiten for rarely required water wall topping, in a known in principle according to the prior art type over the main post respective adapter 50 are slipped into the post extensions can be inserted and after which further plate elements can be inserted into existing post grooves. In addition to the steel cables already described barbed wire applications or the like can be mounted. Existing plate elements and posts form a solid unit after assembly with the concrete tub, which withstands strong impact and explosive attacks, as all components are interlocked, wedged and connected with high-strength straps and ropes. Thus, the wall stays together and no dangerous objects fly through the area. The cover of the reinforced concrete tub can be designed so that it provides a (hollow against rainfall) watertight hollow and storage space for stored there components. In particular, the protective wall can be erected without electrical or hydraulic aids, which can easily fail in the event of a disaster. Maintenance costs are eliminated because the stored components are maintenance-free.

The protective wall according to the invention can also be readily adapted to the geographical conditions and has a long life. Because the concrete tub is sunk into the ground. In the cover plates can also be incorporated according to customer requirements, different surfaces and flush with the surrounding surface, thus preserving the cityscape and the visual impression of the cityscape is not changed by a built-in tub.

The cross bar, where the post is applied, passes through the concrete tub and has at one end the abutment. Depending on the customer's wishes and local conditions, various load transfer systems such as bored piles, angles, sheet pile wall brackets and concrete anchors can be attached to the crossbar to ensure optimum load transfer to the underground foundation system.

Due to the various aids, in particular various reinforcing means, the protective wall is also able to withstand not only the hydraulic water pressure, but also in individual cases adjusting flow forces as well as shock loads from driftwood or the like. Numerous usable additional posts can provide for a specific durability or support of the protective wall. Sandbags and plastic sheeting are not required.

The accumulating when the protective wall in the concrete tank and / or tub of high-strength material accumulating water can be pumped out easily.

The protective wall according to the invention can be used in particular as a flood barrier, but also as a temporary object or building protection or privacy barrier, which withstands any external effects of violence such as shocks or explosions.

By opening the cover, a great protection is achieved in the lower part of the protective wall (in particular against the attachment of stones as well as to minimize the risk that cars can drive through terrorist attacks).

The reinforced concrete tub is laid like a pipe. It eliminates complex measuring work for mounting plates, foundations and basic seals.
