Abstract
The utility model discloses a constructing device for building foundation, in particular to a pile driving immersed tube for building foundation construction. The pile driving immersed tube is formed by a hollow tube-shaped tube body, bottom portions of at least two guide wings which are arranged circumferentially and metal pile heads, the bottom portions are arranged at the lower end of the tube body, the metal pile heads are arranged in the lower end of the bottom portions, wherein the cross section of the tube body is in square shape, the tube body is in multi-section structure, and two adjacent sections of the tube body are connected via rivets. The front end of the metal pile head is equipped with a metal probe. Corrugations are arranged on the metal pile heads. The metal pile heads are equipped with corrugations, thereby reducing resistance force of the immersed tube when moving downwards, and increasing construction efficiency.
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.But present metal pile head is cone, can produce very big resistance when immersed tube moves downward, and influences efficiency of construction.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 provide a kind of foundation construction with driving piles immersed tube, purpose is to improve speed, the pipe shaft that immersed tube moves downward to be connected firmly, and simplified structure, increases bearing capacity of single pile, reduces cost, can detect the immersed tube that immersed tube has arrived hardpan, convenient construction.
The utility model realizes that the technical scheme of purpose is: foundation construction piling immersed tube, it is by the pipe shaft of hollow tubular, along circumferentially the bottom and the metal pile head of at least two guide vanes of setting constitute, the pipe shaft lower end is located in the bottom, metal pile head is arranged on the inside, lower end of bottom, the cross section of pipe shaft is square, the front end of metal pile head is provided with a metal probe, pipe shaft is a multi-segment structure, connect by rivet between adjacent two sections pipe shafts, the metal probe is the aciculiform structure, and described metal pile head is provided with ripple.
The bottom of described bottom is provided with pin-and-hole.
The utility model compared with prior art because metal pile head is provided with ripple, thereby the resistance when having reduced that immersed tube moves downward has been saved the working time, has improved efficiency of construction, is fit to very much construction and uses.
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.
Fig. 2 is the structural representation of metal pile head of the present utility model.
Among the figure 1, pipe shaft; 2, bottom; 3, guide vane; 4, metal pile head; 5, pin-and-hole; 6, metal probe; 7, rivet; 8, ripple.
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 foundation construction piling immersed tube, it is by the pipe shaft 1 of hollow tubular, along circumferentially the bottom 2 and the metal pile head 4 of at least two guide vanes 3 of setting constitute, pipe shaft 1 lower end is located in bottom 2, metal pile head 4 is arranged on the inside, lower end of bottom 2, wherein the cross section of pipe shaft 1 is square, and pipe shaft 1 is a multi-segment structure, connects by rivet 6 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.The front end of metal pile head 4 is provided with a metal probe 6, and metal probe 6 is the aciculiform structure.Metal pile head 4 is provided with ripple 8.
