Abstract
The utility model discloses a building foundation construction facility, in particular to a piling immersed tube used for the building foundation construction, comprising a hollow pipe type pipe body(1), at least two bottoms(2) of the two guide vanes(3) arranged along the circumferential direction, the bottom(2) is arranged on the lower end of the pipe body(1), the section of the pipe body(1) is a rotundity and in a multi-stage structure, the contiguous two pipe bodies(1) have a threaded connection. Compared with the prior art, the utility model has guaranteed the proportional relation between the pipe body and the inside diameter of the bottom, having a simple and rational structure and strong practicability, making the bearing capacity of single pile achieving the design standards. The utility model makes the pipe body into a multi-stage structure, reducing the processing difficulty and cost of the piling immersed tube. The utility model is easy to be brought into operation in the engineering, in favor of spread and exploitation.
Description
Technical field
The utility model relates to a kind of construction foundation working equipment, particularly a kind of construction foundation working piling immersed tube.
Background technology
In the pile foundation engineering of soft foundation, generally adopt tube-sinking cast-in-situ pile, three kinds of preformed pile and large diameter bored piles at present.And what be most widely used is tube-sinking cast-in-situ pile, when executing immersed tube is passed the weak soil layer, takes out metal pile head after reaching the design elevation hardpan, and the bottom-expanding equipment of expanded bore pile being lowered in the immersed tube cuts the earth, fetches earth again forms the expanded bore pile base cavity pocket.
The pipe shaft of present piling immersed tube is all-in-one-piece structure, and pipe shaft is very long, and processing is difficulty very, and the cost height.For these reasons, immersed tube in the past has further improved necessity.
The utility model content
The problem that the utility model exists at above-mentioned prior art, and a kind of piling immersed tube is provided, purpose be simplified structure, increase bearing capacity of single pile, reduce cost, make easy to process.
The utility model realizes that the technical scheme of purpose is: a kind of piling immersed tube, it constitutes by the pipe shaft of hollow tubular with along the bottom that at least two guide vanes circumferentially are set, and the pipe shaft lower end is located in the bottom, and the cross section of pipe shaft is circular, pipe shaft is a multi-segment structure, is threaded between adjacent two sections pipe shafts.
The bottom of described bottom is provided with pin-and-hole.
The utility model has compared with prior art guaranteed the proportionate relationship of pipe shaft and bottom internal diameter, and it is simple and reasonable, practical, makes bearing capacity of single pile reach design standard.The utility model is made multisection type with pipe shaft, has reduced piling immersed tube difficulty of processing and cost, and the utility model is implemented in engineering easily, is beneficial to apply.
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Among the figure 1, pipe shaft; 2, bottom; 3, guide vane; 4, metal pile head; 5, pin-and-hole.
The specific embodiment
Below embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
As shown in Figure 1, the utility model piling immersed tube, it constitutes by the pipe shaft 1 of hollow tubular with along the bottom 2 that at least two guide vanes 3 circumferentially are set, pipe shaft 1 lower end is located in bottom 2, the cross section of pipe shaft 1 is circular, and pipe shaft 1 is a multi-segment structure, is threaded between adjacent two sections pipe shafts 1.The bottom of bottom 2 is provided with to be convenient to combine and the pin-and-hole 5 of throwing off usefulness with its matching used metal pile head 4.
Claims (2)
1, a kind of piling immersed tube, it is characterized in that it constitutes by the pipe shaft (1) of hollow tubular with along the bottom (2) that at least two guide vanes (3) circumferentially are set, pipe shaft (1) lower end is located in bottom (2), the cross section of pipe shaft (1) is circular, pipe shaft (1) is a multi-segment structure, is threaded between adjacent two sections pipe shafts (1).
2, piling immersed tube according to claim 1 is characterized in that the bottom of described bottom (2) is provided with pin-and-hole (5).
