Description

A kind of construction equipment for underwater plate

Technical field

The utility model relates to construction of soft soil treatment field of mechanical technique more particularly to a kind of constructions for underwater plate Equipment.

Background technique

With the Fast Construction of marine economy, new industry and population will be concentrated constantly to coastal region, accelerate ecology The development for enclosing tideland for cultivation construction encloses area's backfill mainly using mud hydraulic reclamation, since the mud water content of hydraulic reclamation is big, soil body particle is thin, stream Dynamic property is strong, therefore is all difficult to consolidate under field conditions (factors) from three to five years, has seriously affected the construction process in hydraulic reclamation area later period.And by The big, low bearing capacity in the cohesive strength of beach, Underwater Soft Foundation mud, therefore engineering construction can not be carried out.Plastic draining board a roll The general 200m of total length, and the length of vertical drainage plate is generally between 10 ~ 50m in foundation treatment engineering, therefore coiled row Water plate needs to be cut into after many sections again inserting piling to ground depth.So need to design it is a kind of can underwater plate construction Equipment is inserted into drain bar, to carry out draining.

Summary of the invention

The technical problem to be solved by the utility model is to overcome problems of the prior art, provide a kind of use In the construction equipment of underwater plate.

To solve the above-mentioned problems technical scheme of the utility model is as follows:

A kind of construction equipment for underwater plate, including working ship are provided on the deck of working ship for inserting under water The pile frame of drain bar construction, pile frame is vertical with the deck of hull, and liftable plate equipment is provided on pile frame, and pile frame side is also set It is equipped with the cutter for cutting underwater draining board.

The cutter is a nested structure, and cutter connects a rope, and cutter is inserted in underwater drain bar, from sea bed The above certain altitude cutting, as cut drain bar at the above 200mm of sea bed.

It is provided with 12 plate equipment on the pile frame, 12 drain bar plate constructions can be carried out simultaneously.

It is provided with high-frequency hydraulic driving hammer at the top of the plate equipment, drives plate equipment construction.

Beneficial effect, the utility model can increase substantially the radical of disposable plate, one time plate 12, raising is applied Work efficiency rate；Driving method by changing plate can shorten the construction time of a plate, improve construction efficiency；Pass through change The length of drain bar can be adjusted flexibly in the cutting technique of drain bar, so that drain bar is adapted to the variation of Different Strata, make at ground Manage consolidation effect more evenly, while can be to avoid the waste of engineering material.

Detailed description of the invention

It is described in detail the utility model with reference to the accompanying drawings and detailed description.

Fig. 1 is a kind of underwater plate working ship side structure schematic view described in embodiment 1.

Fig. 2 is cutter schematic diagram described in embodiment 1.

Fig. 3 is 1 drain bar arrangement schematic diagram of embodiment.

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.

Referring to Fig. 1,2 quantity of plastic drain board flashboard machine on workboat is promoted by present 1 ~ 4 to 12.Plate Machine cannot be distributed two sides on the quarter, but all set at the boat, configure by the pile frame 1 of Specialty Design, while by structure Counterweight ensures the anterior-posterior balance of workboat.

Using the board-plugging device of hydraulic-driven using the active motor of 220kW and the hydraulic pump of 180cc/min, it is capable of providing Continue, stable high-level pressure, thus quick and stable drain bar is inserted into predetermined soil layer.With 30 meters of long plastics For drain bar, a plastic draining board is set, traditional board-plugging device needs 150 seconds, and the hydraulic board-plugging device of this programme only needs 60 seconds, required time was only original 40%, and efficiency greatly improves.

Traditional marine flashboard boat, can only be according to the drain bar length recommended value provided in design drawing in advance by drain bar Cutting section in advance is carried out, when the silt depth when depths changes, the length of drain bar can not be adjusted flexibly again, such as This will affect foundation stabilization effect.

Referring to Fig. 2, this equipment is specially provided with the cutter 3 for cutting underwater draining board, the cutting in pile frame side Device is a set type structure, and cutter connects a rope, and cutter is inserted in underwater drain bar, is cut from bottom.Or from sea bed The above certain altitude cutting, as cut drain bar at the above 200mm of sea bed.

This by the segmentation cutting mode of drain bar by cut in advance be changed to after cut, that is, by drain bar inserting piling to pre- Drain bar is cut off again after calibration is high, and the cutting action carries out automatically under water, since worker can not see sea Situation below face, the rear cutting of drain bar by being automatically performed under water after the absolute altitude of board-plugging device reading drain bar, operate completely Worker need to only check drain bar top, bottom absolute altitude in the operating room of cabin.The rear cutting technique of this drain bar automation, Length difference, the bottom absolute altitude that every drain bar may be implemented are different, to adapt to the fluctuating (referring to Fig. 3) of soil layer.

The full reinforcing to mud depth had not only may be implemented in the technology of this underwater rear cutting drain bar, but also can be to avoid draining Waste of material caused by plate is too long, can not only save project cost, can also improve the uniformity of foundation stabilization, avoid reinforcing There is relative settlement in place afterwards, this has very the demanding engineering of the grounds relative settlement such as airfield runway, building Important meaning.

Beneficial effect: can increase substantially the radical of disposable plate, improve construction efficiency；By changing plate Driving method can shorten the construction time of a plate, improve construction efficiency；It, can be with by changing the cutting technique of drain bar The length of drain bar is adjusted flexibly, so that drain bar is adapted to the variation of Different Strata, makes basement process consolidation effect more evenly, simultaneously It can be to avoid the waste of engineering material.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, the utility model can also on the premise of not departing from the spirit and scope of the utility model There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is special The claimed range of benefit is defined by appended claims and its equivalent.
