Abstract
The utility model discloses a pile-forming device of a sinking pipe prefabricated steel concrete expanded bore pile, in particular relates to a pile-forming sinking pipe, which is a matchable sinking pipe of various sinking pipe prefabricated steel concrete expanded bore piles. The pile-forming sinking pipe is composed of a hollow and tubular pipe body (1), a bottom part (2) and a metal pile head (4). The bottom part (2) is arranged at the lower end of the pipe body (1). The metal pile head (4) is arranged at the inner part of the lower end of the bottom part (2). The front end of the metal pile head (4) is provided with a metal sounding rod (5). The cross-section of the pipe body (1) is circular, the pipe body (1) is in a multi-section type structure, and two adjacent pipe bodies (1) are connected through rivets (6). The front end of the metal pile head of the pile-forming sinking pipe is provided with a metal sounding rod which not only can be used as a hardpan probe, but can press a small space in hardpan, and benefits for the taking out of the metal pile head from the sinking pipe.
Description
Technical field
The utility model relates to a kind of pile-forming equipment of pipe sinking prefabricated steel concrete club-footed pile, and particularly a kind of pile-formation sunken tube is the supporting immersed tube of various precast reinforced concrete piles.
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.Can't detect immersed tube when present immersed tube is constructed at the scene and whether arrive hardpan, also there is a kind of pile-formation sunken tube at present, between the pipe shaft of this immersed tube by being threaded, but find that in practice the connection of thread between this immersed tube multisection type pipe shaft causes the junction insecure because falling into of soil arranged after use a period of time especially easily, and then influence the stability of entire equipment.For these reasons, immersed tube in the past has further improved necessity.
The utility model content
The utility model is at the problem that above-mentioned prior art exists, provide a kind of rational in infrastructure, can detect immersed tube and arrived the pile-formation sunken tube that hardpan, convenient construction and pipe shaft are connected firmly.
The utility model realizes that the technical scheme of purpose is: the supporting pile-formation sunken tube of precast reinforced concrete pile, it is made of pipe shaft, bottom and the metal pile head of hollow tubular, the pipe shaft lower end is located in the bottom, metal pile head is arranged on the inside, lower end of bottom, the front end of metal pile head is provided with a metal probe, the cross section of pipe shaft is circular, and pipe shaft is a multi-segment structure, passes through rivet between adjacent two sections pipe shafts.
The utility model compared with prior art, pipe shaft is a multi-segment structure, by rivet, processing technology is simple between adjacent two sections pipe shafts, cost of production is low, the good stability of equipment during use.And being provided with a metal probe at the front end of metal pile head, it both can make ground hardpan survey meter, can extrude an individual very little space again in hardpan, was beneficial to metal pile head and extracted in immersed tube.
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; 4, metal pile head; 5, metal probe; 6, rivet.
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 structure of the utility model pile-formation sunken tube is as follows, and it is made of pipe shaft 1, bottom 2 and the metal pile head 4 of hollow tubular, and pipe shaft 1 is a multi-segment structure, rivets by rivet 6 between adjacent two sections pipe shafts 1.Pipe shaft 1 lower end is located in bottom 2, and metal pile head 4 is arranged on the inside, lower end of bottom 2, and the cross section of pipe shaft 1 is circular, and the front end of metal pile head 5 is provided with a metal probe 5.
Claims (1)
1, the supporting pile-formation sunken tube of precast reinforced concrete pile, it is made of pipe shaft (1), bottom (2) and the metal pile head (4) of hollow tubular, pipe shaft (1) lower end is located in bottom (2), metal pile head (4) is arranged on the inside, lower end of bottom (2), the front end of metal pile head (4) is provided with a metal probe (5), the cross section of pipe shaft (1) is circular, it is characterized in that pipe shaft (1) is a multi-segment structure, rivets by rivet (6) between adjacent two sections pipe shafts (1).
