Artificial Shaft Pipe Pile and Construction Technology of Pipe Pile

Abstract

The invention discloses an artificial shaft pipe pile, which comprises a pipe body, a first annular groove is arranged on the upper end of the outer circle of the pipe body, the first annular groove is concentric with the pipe body, and a lower end of the outer circle of the pipe body is arranged There is a second annular groove, the soil cutting ring is fixedly connected in the second annular groove, the cross section of the soil cutting ring is L-shaped, and the outer diameter of the soil cutting ring is equal to or smaller than that of the pipe body Outer diameter, the soil-cutting ring is set opposite to the first annular groove, the elevation of the lower end surface of the soil-cutting ring is lower than the lower end surface of the pipe body, and the inner circular surface of the pipe body is provided with a third annular groove. A ring cutting device is installed in the third annular groove, and the ring cutting device is used for ring cutting the soil layer under the pipe body. In the invention, by rotating the round rod, the screw rod moves relative to the round rod, so that the cutter moves along the axial direction of the installation rod, the cutter cuts into the soil layer and adjusts the feed rate in real time, and pushes the installation rod to make a circular motion in the pipe body, and the cutter Excavate the soil between the bottom of the pipe body and the soil cutting ring.

Description

technical field [0001] The invention relates to the technical field of maintenance wells, in particular to artificial shaft piles and construction techniques for pipe piles. Background technique [0002] In building construction, the use of large-diameter ultra-deep prestressed pipe piles is becoming more and more extensive. Prestressed pipe piles have the advantages of good pile quality, high single pile bearing capacity, fast construction speed, short construction period, and low cost. In the process of hole formation, no mud wall protection is required, which avoids a large amount of mud waste and realizes green construction. [0003] Existing pipe pile construction is generally carried out by hammering and static pressure. On the one hand, the construction produces relatively loud noises. On the other hand, the prefabricated pipe piles in the processing plant need to be cut and segmented. It is easy to shift during the process, which affects the construction quality. ...
