Background
The cast-in-place pile is a pile formed by forming a hole in place and pouring concrete or reinforced concrete. Commonly used are: (1) drilling a cast-in-place pile: the pile is formed by using a spiral drilling machine, a diving drilling machine and the like to form holes on site and pouring concrete, and the construction has no vibration and does not squeeze soil, but the settlement amount of the pile is slightly larger.
(2) And sinking the pipe and pouring the pile: the steel pipe with reinforced concrete pile shoe (pile tip) or valve type pile shoe is sunk into the soil by hammering or vibration, then concrete is poured in and the pipe is pulled out simultaneously to form the pile.
When the cast-in-situ bored pile is constructed, firstly, holes are drilled through equipment, then a pile frame formed by the steel mesh cage is sunk into the holes, and then concrete or reinforced concrete is poured into the holes to form the cast-in-situ bored pile. In the construction process, a post-grouting construction method is used, wherein the post-grouting is to fill slurry into a pre-embedded grouting pipe through a high-pressure pump when the concrete of a pile body reaches a certain strength after the pile is formed, the slurry breaks through a valve at the bottom of the grouting pipe to crack the soil body at the bottom of the pile body, and the slurry enters the crack, so that the strength of the soil body and the coaction performance of the pile body and the soil body are improved. The quality of the grouting is therefore directly dependent on the integrity and openness of the mud jacking pipe.
The conventional installation to the mud jacking pipe is with the mud jacking pipe direct welding and pile frame steel reinforcement cylinder mould outside, and the drawback of doing so has: welding must lead to the fact the damage to the mud jacking pipe wall, and the mud jacking pipe is in the pile frame outside, and the in-process is transferring can be difficult to avoid frequently bumping with the pore wall, and the mud jacking pipe of modelling is buckled the dislocation easily like this, and is difficult to carry out position control after the mud jacking pipe welding is accomplished, and the fault-tolerant rate is low, and the rework cost is high.
