Abstract
The utility model discloses a pile-forming device of a sinking pipe prefabricated steel concrete expanded bore pile, in particular relates to a sinking pipe, which is a matchable sinking pipe of various sinking pipe prefabricated steel concrete expanded bore piles. The pile-forming device is composed of a hollow and tubular pipe body and a bottom part which is arranged at the lower end of the pipe body, the cross-section of the pipe body is circular, the pipe body is in a multi-section type structure, two adjacent pipe bodies are connected through rivets, the upper side of the outer wall of the bottom part is provided with a sealing ring, and the lower part of the pipe body is sheathed with a sealing ring. The diameter of the sealing ring arranged at the upper end is greater than that of the sealing ring arranged at the lower end. The outer wall of the pipe body of the pile-forming device is provided with the sealing ring, sullage is prevented from entering a conical hollow cavity when a metal pile head is taken out, the time of sullage entering the conical space is prolonged, and thus the expanded bore work can be continued to be carried out, and the sinking pipe is suitable for coastal regions to use. The pipe body of the pile-forming device is in a multi-section type, the manufacturing difficulty and the cost of the sinking pipe are lowered.
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 construction piling immersed 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.
Present immersed tube only is fit to use interiorly, can't use in the coastal area, because after metal pile head takes out, formed a conical cavity, outside the pipe and between in the pipe pressure reduction is arranged, mud above the hardpan easily enters in the conical cavity, make the expansion basic skill or training do and to carry out, cause immersed tube to be restricted in the use of coastal area.The pipe shaft of immersed tube is all-in-one-piece structure at present, and pipe shaft is very long, and processing is difficulty very, and the cost height.Also there is a kind of immersed tube at present, between the pipe shaft 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, increase bearing capacity of single pile, low, the good stability of cost, and the immersed tube that uses of suitable coastal area.
The utility model realizes that the technical scheme of purpose is: the supporting immersed tube of precast reinforced concrete pile, it is made of the pipe shaft and the bottom of hollow tubular, the pipe shaft lower end is located in the bottom, the cross section of pipe shaft is circular, the top of bottom outer wall is provided with sealing ring, and the bottom of pipe shaft is set with sealing ring, and the diameter of the sealing ring on being arranged on is greater than the diameter of the sealing ring that is arranged on the lower end, pipe shaft is a multi-segment structure, passes through rivet between adjacent two sections pipe shafts.
Described sealing ring is made of a metal ring body and a circle flange of being located at its lower end.
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.Owing on the outer wall of pipe shaft, be provided with sealing ring, after taking out, metal pile head stopped that mud enters in the conical cavity, prolonged time that mud enters cone space, make the expansion basic skill or training do and to proceed, making immersed tube also be adapted at the coastal area uses, connect by rivet between the multisection type pipe shaft of the present utility model, reduced immersed tube difficulty of processing and cost, and good stability when using.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; 4, metal pile head; 5, sealing ring; 6, sealing ring; 7, 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 supporting immersed tube of the utility model precast reinforced concrete pile, it is made of the pipe shaft 1 and the bottom 2 of hollow tubular, pipe shaft 1 lower end is located in bottom 2, and the cross section of pipe shaft 1 is circular, and pipe shaft 1 is a multi-segment structure, rivet by rivet 7 between adjacent two sections pipe shafts 1, the top of bottom 2 outer walls is provided with sealing ring 6, and the bottom of pipe shaft is set with sealing ring 5, and the diameter of the sealing ring 5 on being arranged on is greater than the diameter of the sealing ring 6 that is arranged on the lower end.Sealing ring is made of a metal ring body and a circle flange of being located at its lower end.
