Pile sinking construction method for precast concrete plank pile
The invention relates to a pile sinking construction method for a precast concrete plank pile. The construction method includes the steps that firstly, a crane is used for vertically lifting up the plank pile to a pile position for primary position, and the plank pile is inserted into the soil layer through the self gravity of the plank pile; secondly, a centering device is used for clamping a pile body of the plank pile, and verticality adjustment and construction axis correction are carried out; thirdly, after correction and straightening are finished, a hook, for hooking the pile, of the crane is released, a hydraulic impacting pile hammer is lifted, and the pile top is sleeved with a pile top steel cap at the lower end of a hammer head of the pile hammer; fourthly, after the pile top is sleeved, pile driving is carried out, the sinking pile verticality is monitored anytime in the driving process, and the inclination of the pile body in all the directions is corrected in time through the centering device in order to keep vertical pile sinking of the plank pile; and fifthly, when pile sinking is carried out to the designed elevation preset value position of the pile top distance, the centering device is released, and pile driving construction continues until the pile top is fed to the designed elevation. According to the construction method, the pile forming quality is good, tidy and tight matching degree of joints between plank piles can be well guaranteed, the construction speed is high, and the work efficiency is high.
