Pilot replacing device of fore shaft steel pipe pile and fore shaft steel pipe pile sinking method thereof
The invention discloses a replacing and driving device of a mouth-locking steel pipe pile and a pile sinking method of the mouth-locking steel pipe pile. The replacing and driving device comprises a transition steel pipe pile, a fastening batten, an anti-falling lifting lug, a stiffening triangular plate, a force transmission circular plate and a cross plate. The construction method comprises the following steps: S1, preparing a replacement device; s2, locking steel pipe piles are positioned; and S3, re-driving and pile sinking are conducted on the fore shaft steel pipe pile, and the fore shaft steel pipe pile is driven into the rock stratum through combination of a driving replacing device and a hydraulic impact hammer. The hydraulic impact hammer can be suitable for inserting and driving the fore shaft steel pipe piles under the bare rock geological condition, inserting and driving of the hydraulic impact hammer under the condition that the clear distance between the adjacent fore shaft steel pipe piles is insufficient are achieved through the arrangement of the driving replacing device, and the problem that in the pile sinking process of the hydraulic impact hammer, the adjacent fore shaft steel pipe piles conflict with a sleeve head of the hydraulic impact hammer is solved; the construction quality of the fore shaft steel pipe pile under the bare rock geological condition is improved, hydraulic impact hammer pile sinking of the fore shaft steel pipe pile under the bare rock geological condition can be achieved, the practicability is high, and the applicability is wide.
本发明公开了一种锁口钢管桩的替打装置及其锁口钢管桩沉桩方法，该替打装置包括：过渡钢管桩、紧固板条、防坠吊耳、加劲三角板、传力圆板、十字板。施工方法包括如下步骤：S1、替打装置准备；S2、锁口钢管桩的定位；S3、锁口钢管桩复打沉桩，使用替打装置与液压冲击锤的组合将锁口钢管桩打入岩层。本发明能适用于裸岩地质情况下锁口钢管桩的插打，通过设置替打装置，实现了相邻锁口钢管桩在桩净间距不足情况下的液压冲击锤插打，解决了液压冲击锤沉桩过程中相邻锁口钢管桩与冲液压击锤的套头冲突的问题，提升了裸岩地质条件下锁口钢管桩的施工质量，能够实现裸岩地质条件下的锁口钢管桩的液压冲击锤沉桩，实用性强，适用性广泛。
