Artificial vertical shaft pipe pile and pipe pile construction process
The invention discloses an artificial vertical shaft pipe pile. The pipe pile comprises a pipe body, a first annular groove is formed in the upper end of the outer circle of the pipe body, the first annular groove and the pipe body are concentric, a second annular groove is formed in the lower end of the outer circle of the pipe body, a soil cutting circular ring is fixedly connected into the second annular groove, the cross section of the soil cutting circular ring is in an L shape, the outer diameter of the soil cutting circular ring is equal to or smaller than that of the pipe body, the soil cutting circular ring is opposite to the first annular groove, the elevation of the lower end face of the soil cutting circular ring is smaller than the lower end face of the pipe body, a third annular groove is formed in the inner circular face of the pipe body, an annular cutting device is arranged in the third annular groove, and the annular cutting device is used for conducting annular cutting on a soil layer below the pipe body. According to the pipe pile, a round rod is rotated, and a screw rod moves relative to the round rod, so that a cutter moves in the axial direction of a mountingrod, the cutter cuts into a soil layer, the feeding amount is adjusted in real time, the mounting rod is pushed to do circular motion in the pipe body, and the cutter digs out soil between the lowerportion of the pipe body and the soil cutting circular ring.
本发明公开了人工竖井管桩，包括管体，所述管体的外圆上端设有第一环状槽，所述第一环状槽与管体同心，所述管体的外圆下端设有第二环状槽，所述第二环状槽内固定连接切土圆环，所述切土圆环的横断面呈L型，所述切土圆环的外径等于或小于管体的外径，所述切土圆环与第一环状槽相对设置，所述切土圆环下端面标高小于管体下端端面，所述管体的内圆面设有第三环状槽，所述第三环状槽内装有环切装置，所述环切装置用于管体下方土层环切。本发明通过转动圆杆，螺杆相对于圆杆移动，使得切刀沿安装杆的轴向移动，切刀切入土层内并实时调整进给量，推动安装杆在管体内作圆周运动，切刀将管体下方到切土圆环之间的土壤挖除。
