Abstract

The utility model discloses a foundation pit supporting structure with a water falling function. The foundation pit supporting structure with the water falling function comprises support pile columns which are formed by hollow steel pipes. Vertical sliding grooves are respectively arranged at two sides of the hollow steel pipes. Water drainage holes are evenly arranged along the inner side face of the vertical sliding grooves. Steel pipe pile caps are arranged on the upper end face of the hollow steel pipes, the lower ends of the hollow steel pipes are arranged on pipe pile clamp rings, and reinforced concrete cone-shaped pressure heads are arranged at the lower ends of the pipe pile clamp rings. According to the foundation pit supporting structure with the water falling function, construction cost can be reduced, recycle is achieved, and a water drainage function is provided.

Description

A kind of foundation pit supporting construction that contains the precipitation function
Technical field
The utility model relates to the supporting and protection structure in a kind of structure foundation construction, especially relates to a kind of foundation pit supporting construction that contains the precipitation function.
Background technology
Any building, the excavation and support of its foundation ditch all is inevitably to build operation, the input of base pit engineering is very large usually, millions of units at least, at most several ten million.At present especially the supporting of deep-foundation pit engineering and precipitation design respectively and construct base pit engineering, supporting and protection structure mainly contains bored pile, steel sheet pile, the structure such as diaphragm wall, piled anchor, the construction costs of these supporting and protection structure is very high, and can not recycle, caused huge waste, foundation pit dewatering adopts around foundation ditch or inner special dewatering well and the water-stop curtain of foundation ditch realized, water-stop curtain is generally three axle soil-cements or flyash agitation pile (wall), the construction space of foundation ditch inside is diminished, and greatly improved construction costs.
The utility model content
The purpose of this practicality is to overcome above-mentioned deficiency of the prior art, and a kind of construction costs that reduces is provided, and recoverable, and integrates a kind of foundation pit supporting construction that contains the precipitation function of drain function.
The purpose of this utility model is achieved by following technical proposals: a kind of foundation pit supporting construction that contains the precipitation function, comprise the supporting pile, described supporting pile is that hollow steel pipe consists of, the dual-side of described hollow steel pipe is respectively arranged with vertical chute, medial surface along described vertical chute evenly is provided with drain hole, the upper surface of described hollow steel pipe is provided with the steel pipe pile cover, the lower end of described hollow steel pipe is arranged on the pile tube collar, and the lower end of described pile tube collar is provided with the steel concrete conical indenter.
Be inserted with steel plate for sealing water in the chute between described per two adjacent hollow steel pipes, the thickness of described steel plate for sealing water is 15mm.
The diameter of described drain hole is 8-12mm.
The tapering of described conical indenter is 45 °.
The pipe thickness of described hollow steel pipe is 20mm.
Be provided with submersible pump in the described hollow steel pipe.
The beneficial effects of the utility model are: mainly bear the foundation ditch lateral pressure (comprises soil pressure to the hollow steel pile tube on the one hand, hydrostatic pressure, flowing pressure, the ground preloading), guarantee the security and stability into the hole, can be used as again on the other hand the foundation pit dewatering well, the underground water of foundation ditch inside can be by the draining aperture of hollow steel pile tube inboard, seepage flow is in the hollow steel pile tube, as being put into hollow steel pipe, QSP40-16-3 type submersible pump draws water, can effectively reduce the groundwater table of foundation ditch, steel plate for sealing water (15mm is thick) is inserted in the steel pipe side direction chute of two adjacent reducing hollow steel pipe sidewalls, can stop the outer water of foundation ditch to enter to be seeped into foundation ditch inside, affect the inner normal construction of foundation ditch, guarantee that the foundation ditch interior construction has the environment of a drying, hollow steel pipe is placed on 45 ° of conical indenter steel pipe piles of steel concrete collar, because 45 ° of conical indenter bottoms of steel concrete are tapered, so being pressed into the resistance that is subject in the foundation pit side-wall soil body process at hollow steel pipe will reduce, above-mentioned material is recyclable after using, reuse, therefore can reduce the waste of material, reduce the cost of engineering.
Description of drawings

Fig. 2 is Fig. 1 hollow core steel pipe pile cross-sectional structure schematic diagram.
Fig. 3 is that hollow steel pile tube of the present invention arranges the plane structure schematic diagram.
Fig. 4 is that hollow steel pile tube of the present invention is pressed into the soil mass of foundation pit schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figures 1 to 4, a kind of foundation pit supporting construction that contains the precipitation function, comprise supporting pile 1, described supporting pile 1 consists of for hollow steel pipe, the pipe thickness of described hollow steel pipe is 20mm, the utility model is provided with submersible pump 8 in hollow steel pipe, be used for extracting the water of foundation ditch, dual-side at described hollow steel pipe is respectively arranged with vertical chute 2, be inserted with steel plate for sealing water 7 in the chute between described per two adjacent hollow steel pipes, surface along the inboard hollow steel pipe of described vertical chute 2 evenly is provided with drain hole 3, and the diameter of described drain hole 3 is 8-12mm.The upper surface of described hollow steel pipe also is provided with steel pipe pile cover 4, and the lower end of described hollow steel pipe is arranged on the pile tube collar 5, and the lower end of described pile tube collar 5 is provided with steel concrete conical indenter 6, and the tapering of described conical indenter 6 is 45 °.
The operating process of the utility model foundation pit supporting construction:
(1) according to working drawing, determines the position of each steel pipe pile with transit, and make marks with little wooden stake;
(2) before excavation of foundation pit, with draining aperture on the sidetracking in the hollow steel pipe, then hollow steel pipe is placed on 45 ° of conical indenter steel pipe piles of steel concrete collar, with the large-tonnage Static pressure pile driver hollow steel pipe is pressed into projected depth;
(3) QSP40-16-3 type submersible pump is put into hollow steel pipe draw water (its top hang over top rebars hook on).
(4) stage excavation foundation ditch whenever digs one deck, the thick steel plate for sealing water of 15mm is inserted in the steel pipe side direction chute of two adjacent reducing hollow steel pipe sidewalls, presses downward in the soil body, and each loops, until dig projected depth.
