Detachable spiral press-in piece, pipe pile torsion press-in device and construction method
The detachable spiral press-in piece comprises a connecting cap, a connecting rod and a spiral press-in head, the connecting cap and the spiral press-in head are connected through the connecting rod, and the spiral press-in head is in a bidirectional gyroscope shape up and down. An upper screwer and a lower screwer are arranged on the peripheries of the upper portion and the lower portion of the spiral press-in head respectively. The pipe pile twisting and pressing-in device comprises the detachable spiral pressing-in piece, a pipe pile and a hoop twisting device, a clamping groove is formed in the inner wall of the top end of the pipe pile, the connecting cap is clamped in the clamping groove, and the hoop twisting device is erected on the periphery of the upper end of the pipe pile. According to the construction method, torque is applied to the pipe pile through the hoop twister, the pipe pile drives the spiral press-in head to be pressed into a soil body, and the soil squeezing effect is reduced; after the pipe pile reaches the set depth, the upper screwer can cut a soil plug, the spiral press-in head is twisted and screwed out of the pipe pile, the whole method is low in noise, the spiral press-in head can be detached and recycled, and cost is saved; meanwhile, the spiral press-in head is placed at the bottom of the pipe pile, and the soil plug blocking effect is reduced.
一种可拆卸螺旋压入件、管桩扭转压入装置及施工方法，可拆卸螺旋压入件包括连接帽、连接杆和螺旋压入头，连接帽和螺旋压入头通过连接杆连接，螺旋压入头上下呈双向陀螺状，螺旋压入头上部和下部的外围分别设置上螺纹刀和下螺纹刀。管桩扭转压入装置包括上述可拆卸螺旋压入件以及管桩和环箍扭转器，管桩顶端内壁设置有卡槽，连接帽卡设在卡槽中，环箍扭转器架设在管桩上端外围。施工方法通过环箍扭转器给管桩施加扭矩，管桩带动螺旋压入头压入土体，减小挤土效应；管桩到达设定深度后，上螺纹刀可切割土塞，使螺旋压入头扭转旋出管桩，整个方法噪音小，螺旋压入头可拆卸循环使用，节约成本；同时螺旋压入头放置在管桩底部，减小了土塞闭塞效应。
