Abstract

The invention discloses a novel rapid connecting device and method for following pipe piles while drilling. The connecting device comprises an upper connecting part, a lower connecting part, a steel sleeve, screws, nuts and anchoring reinforcing steel bars; the upper connecting part and the lower connecting part are arranged at two ends of the pipe pile; the screws are arranged on the circumference of the upper connecting part and the circumference of the lower connecting part; one end of each screw is connected with a prestressed reinforcing steel bar of the pipe pile; the outer circumference of the upper connecting part and the outer circumference of the lower connecting part of the adjacent pipe pile are sleeved with the steel sleeve; the nuts and the screws are matched to fix the steel sleeve; one end of each anchoring reinforcing steel bar is connected with the prestressed reinforcing steel bar, and the other end is perpendicular to the end surface of the pipe pile to extend out; anchoring holes are formed in the lower connecting part of the pipe pile; and filler is arranged in the anchoring holes. With the device and the method, the mounting mechanization degree is high, welding is avoided, the construction difficulty of workers is reduced, the working efficiency is improved, the pull-out capacity, the sealing performance and the pressure of pile side grouting of the following pipe piles while drilling are guaranteed, grouting bodies are prevented from entering pipe pile inner holes, and the project quality of the pipe piles is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of connecting pipe piles while drilling, and in particular relates to a novel quick connection device and method for pipe piles while drilling. Background technique [0002] Due to the characteristics of high unit bearing capacity, strong geological adaptability and fast mechanized construction speed, pipe piles are widely used in construction projects. A pipe pile machine while drilling and a construction method of pipe piles while drilling (ZL 201210022133.X), in which drilling, pile sinking and soil extraction are carried out simultaneously, and the pile sinking is finally bonded by cement slurry between the pipe wall and the hole wall , civilized and pollution-free construction, it is a green and environmentally friendly pile type, which overcomes the traditional PHC pipe pile foundation pile sinking construction hammering method, static pressure method and pre-drilling method because of its technical ch...
