Abstract
The invention discloses a pipe pile connecting method. Pipe piles are connected with steel pipes. When the pipe piles are prefabricated in a factory, the upper steel pipe and the steel pipe are connected into the upper pipe pile and the lower pipe pile in a sleeved manner respectively, during pile connecting, after the upper pipe pile and the lower pipe pile are aligned, two external embedded section parts of the upper steel pipe are right aligned with two inner embedded groove parts of the lower steel pipe, and after the upper pipe pile is rotated by a certain angle, the two outer embedded section parts are right clamped with the two inner embedded groove parts respectively; and finally, connectors of the upper pipe pile and the lower pipe pile are welded, and the connectors are more stable. The bending resisting capacity and shearing resisting capacity of the connector positions are improved, connecting of the upper pipe pile and the lower pipe pile is very stable, and the stability of the connector positions of the upper pipe pile and the lower pipe pile is improved.
Description
Technical field
The present invention relates to building field, particularly a kind of tubular pile splicing method.
Background technology
In building trade, the length due to a pile does not reach the degree of depth of design code, so need coupling together of preformed pile one one to continue to beat, till the degree of depth squeezing into design downwards.In the process, need preformed pile to carry out pile extension, namely pile extension is the process be connected with the lower end of a rear root canal pile on the top of the last root canal pile squeezed at a piece.Tubular pile splicing method has end plate welding and mechanical connection method two kinds, but the work progress of these two kinds of methods is complicated, and all can cause the interface existing defects of two root canal piles, and make the bending resistance of interface weak, the connection of two root canal piles is built on the sand.
Summary of the invention
The object of the invention is to overcome the shortcoming existed in prior art, a kind of tubular pile splicing method that construction technology is simple, stable connection, interface bending resistance are strong is provided.
Object of the present invention is achieved through the following technical solutions:
A kind of pile tube joint steel pipe, comprises joint steel pipe 1 and lower joint steel pipe 5, is hollow steel tube; The front end outside weldings of upper joint steel pipe 1 has friction lever 2, and the outside weldings of lower joint steel pipe 5 has friction lever 2; Friction lever 2 has screw thread, and friction lever 2 is linked together by concreting and pile tube; The rear end of upper joint steel pipe 1 is provided with the outer block portion of twice, i.e. the outer block portion 3 of first and the outer block portion 4 of second; The inside, front end of lower joint steel pipe 5 is provided with caulking groove portion in twice, i.e. caulking groove portion 7 in caulking groove portion 6 and second in first; Upper joint steel pipe 1 is socketed in the inside of lower joint steel pipe 5, and the outer block portion of twice is slot with caulking groove section in twice and cooperatively interacts and is connected.
A kind of tubular pile splicing method adopts above-mentioned pile tube joint steel pipe, and when pile tube is prefabricated in the factory, the front end of upper joint steel pipe 1 together with the concreting of top pile tube 8, makes the front end sleeve of joint steel pipe 5 be connected on the inside of top pile tube 8 by friction lever 2; In like manner, lower joint steel pipe 5 is also socketed in the inside of bottom pile tube 9; Friction lever 2 there is screw thread, concrete frictional force in steel pipe and pile tube can be increased; During pile extension, after top pile tube 8 is aimed at bottom pile tube 9, at this moment the outer block portion of twice of upper joint steel pipe 1 is also just in time aimed at caulking groove portion in the twice of lower joint steel pipe 5, and after then top pile tube 8 being rotated to an angle, just embedded slot part does not clamp with twice in twice outer block portion; Finally the interface of top pile tube 8 and bottom pile tube 9 is welded, make interface more firm.
The present invention compared with prior art tool has the following advantages and effect:
(1) the present invention top pile tube and bottom pile tube interface position respectively in cover saves steel pipe and lower joint steel pipe, increase bending resistance and the shear resistance of interface position.
(2) the inner sleeve steel pipe on interface makes the connection of upper and lower two root canal piles very firm, improves the stability of its interface position.

Detailed description of the invention
Below in conjunction with embodiment, further detailed description is done to the present invention, but embodiments of the present invention are not limited thereto.
Embodiment
A kind of pile tube joint steel pipe, comprises joint steel pipe 1 and lower joint steel pipe 5, is hollow steel tube; As shown in Figure 1 and Figure 2, the front end outside weldings of upper joint steel pipe 1 has friction lever 2, and the outside weldings of lower joint steel pipe 5 has friction lever 2; As shown in Figure 3, friction lever 2 has screw thread, friction lever 2 is linked together by concreting and pile tube; The rear end of upper joint steel pipe 1 is provided with the outer block portion of twice, i.e. the outer block portion 3 of first and the outer block portion 4 of second; As shown in Figure 4, Figure 5, the inside, front end of lower joint steel pipe 5 is provided with caulking groove portion in twice, i.e. caulking groove portion 7 in caulking groove portion 6 and second in first; As shown in Figure 6, upper joint steel pipe 1 is socketed in the inside of lower joint steel pipe 5, and the outer block portion of twice is slot with caulking groove section in twice and cooperatively interacts and is connected.
A kind of tubular pile splicing method adopts above-mentioned pile tube joint steel pipe, and when pile tube is prefabricated in the factory, the front end of upper joint steel pipe 1 together with the concreting of top pile tube 8, makes the front end sleeve of joint steel pipe 5 be connected on the inside of top pile tube 8 by friction lever 2; In like manner, lower joint steel pipe 5 is also socketed in the inside of bottom pile tube 9; Friction lever 2 there is screw thread, concrete frictional force in steel pipe and pile tube can be increased; As shown in Figure 7, during pile extension, after being aimed at bottom pile tube 9 by top pile tube 8, at this moment the outer block portion of twice of upper joint steel pipe 1 is also just in time aimed at caulking groove portion in the twice of lower joint steel pipe 5, then, after top pile tube 8 being rotated to an angle, just embedded slot part does not clamp with twice in twice outer block portion; Finally the interface of top pile tube 8 and bottom pile tube 9 is welded, make interface more firm.
