CZ1392A3 - Method of foundation engineering along a traffic road, for instance soundproof walls - Google Patents

Abstract

To construct a foundation for a noise barrier, which foundation consists of a number of individual foundations, along a traffic route, e.g. a railway track, running on an embankment, steel sheeting tubes (7) are first of all progressively positioned at the locations provided for the foundations and are lowered into the embankment body (1) while excavating the surrounding soil. Track supports (16) for forming a temporary track (14) for mobile construction equipment are laid across the lowered sheeting tubes (7). By means of this construction equipment, small pillars (18) can be lowered into the ground from this track (14) in the protection of the sheeting tubes (7) and finally - during simultaneous retreat of the track (14) - concrete can be placed in the hollow spaces formed by the sheeting tubes while the same are withdrawn. The sheeting tubes (7) therefore serve as formwork for foundation bodies in which the pillar heads of the small pillars bond in place and on which posts or the like for the noise barrier to be constructed can then be mounted. <IMAGE>

Description

Technical field

The invention relates to a method of foundation of buildings, for example protective securing or noise walls, by a series of individual foundation elements in the immediate vicinity of a clear profile of a transport path lying on the embankment, for example of rail tracks.

BACKGROUND OF THE INVENTION

The continuing effort to protect the environment from emissions that arise on transport routes is causing an increasing number of protective security or noise walls along the transport path. Protective noise walls are not only located along streets, especially highways, but also along railways.

The installation of protective noise walls along roadways running at the height of the landscape does not give rise to problems that arise on railways running on embankments, since there is insufficient working space outside the clear rail profile; Since the embankment crown is not usually accessible to oro heavy construction machines due to the height of the embankment above the landscape, but also due to the terrain permeability on the surface of the landscape, in some cases it may be possible to set up protective main roads. ^T ACTIVE walls practically operate only from itself rail track. Work can only be performed during breaks between trains, which makes work very difficult. In addition, must a slow ride be arranged and a warning guard be placed on the tracks? from s 1, st and vynál and zu

Against this background, the object of the invention can be to achieve an economical way of laying structures, such as protective noise walls, along traffic routes running on the embankment, such as rails, in the immediate vicinity of a clear profile without claiming a clear profile.

This object is achieved according to the invention by the features set forth in the characterizing part of claim 1).

A preferred further embodiment is set forth in the subclaims.

An essential advantage of the method according to the invention consists in the insertion of a steel building pipe for the prior reinforcement of the embankment circumference in which the foundation of the construction is carried out. The construction pipe, which is usually embedded after a slight expansion of the embankment crown, or after the cutting of a part of the mining by a flat contact surface under the bottom of the actual transport road deposited on the embankment forest, has a triple function. It serves first as a substructure for the track, or as a plate for construction machinery, which can be operated outside the clear track profile. Furthermore, the building pipe causes a temporary reinforcement of the embankment body. In protecting it, a pilot, preferably a small drilled pilot, can be embedded in a smaller and less used device than in conventional drilled piles. Finally, the construction pipe serves as a formwork in the manufacture of the individual foundation elements, in which the hollow space formed thereon is concreted while the construction pipe is pulled out.

Not only the embedding of the building pipe, for example with pile drivers or vibrations while extracting the bottom, but also the benefit of small drilled piles are measures that wipe the body of the embankment and do not allow its damage. Nevertheless, small drilled piles in conjunction with the head element formed by them allow reliable foundation of the concrete foundation of the building to be constructed.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is further elucidated by way of example with reference to the drawing, in which:

1 to 7 show a cross-section of a railway embankment in the various stages of the process according to the invention, FIGS. 8a and b show a cross-section of the perimeter of the construction pipe head and also its plan view - both on a larger scale.

DETAILED DESCRIPTION OF THE INVENTION

Giant. 1 shows the initial situation. On the crown 2 of the embankment 1 is a gravel bed JP ^{ro of the} railway track, here the outer track is only indicated. Outside the clear profile of these tracks, a protective noise wall is to be constructed, from which the axis 6 of the protective noise wall is shown. The protective noise wall shall be based on individual foundation elements which are spaced one behind the other along the axis of the protective noise wall. Here, the foundation formed in the axis 6 of the protective noise wall also partially lies in the perimeter of the embankment slope. First, the abutment surface 6 shown in broken lines in FIG. 1 is formed by partial cutting into the crown 2 of the embankment.

As shown in FIG. 2, the building pipe J is formed on the bearing surface of the protective noise wall at the location of the foundation to be built. The building pipe J is made of steel and dimensioned from a static, structural and upsetting point of view and provided at the upper end with a shoulder 8, which is supported by brackets 9. At two mutually opposite locations, the shoulder 8 is widened by bearing brackets 10, which later serve to accommodate the runway beams 14.

As shown in FIGS. 3 and 4, the building pipe J is driven into the embankment body by a ram in the direction of the arrow 11. A conical groove 12 is dug in the base of the building pipe 7 as a relaxation area for the connected pile driving process, into which the building pipe can penetrate after pile driving. .

The ram itself can be carried out either by a ram with a freely falling ram 13 (Fig. 4), the size of which is aligned with the pipe 7, ie it can be inserted into it from the upper side and acting on the upper edge including the shoulder 8. For example, the ram can be used for the pipe 7 and can then be operated with rapid lift. This device can also operate eccentrically so that it can counteract an eventual skew.

If the position on the embankment crown 2 has been reached above the surface of the landscape into which the building pipe is driven, the position and driving on of the landscape surface can be achieved. If this position of construction is not achievable, according to the invention, the pipe head 7 is operated on a roadway 14, which is supported by non-matching building pipes 2. FIG. shows how longitudinal girders 15 are placed over the laterally protruding support brackets 10, which paths 16, e.g. Between the beams 15 a lid 17, for example a grate.

on

The distance of the two track beams from each other is such that they correspond to the gauge of conventional construction machines from above, eg excavators, which can accommodate additional construction tubes 7 in front of the head of the construction tube 7, or 1_. The working bed 19 with the working platform 20, which is applied from the side immediately to the runway beam 16, facilitates the construction measures.

After the pile 18 has been formed, the runway beams 16 and the runner beams 15 are removed and the building tube 7 is pulled out in the direction of arrow 21. Then, the cavity 3e inside the building tube 7 is filled with concrete to form the foundation. The base body 22 thus formed covers the pile head 18 and thus provides the load from the base in one free wall to the piles 18 and through them to the depth of the embankment body 1.

Giant. 7 shows the final state. The base bodies 22 are formed with base mounting apertures 2.2 in which the pillars 24 are located. The lower end of this pillar 24 is formed by a continuous base plate 25. at the top there is a protective noise wall 26 supported by the pillar 24.
