Circular diaphragm wall joint and construction method thereof
The invention discloses a circular diaphragm wall connector which comprises a plurality of sections of diaphragm wall connectors fixedly connected in the vertical direction, and each section of diaphragm wall connector comprises a bottom plate, a plurality of connecting pieces, a plurality of connecting pieces and a plurality of connecting pieces, the height of the semi-cylindrical plug is the same as that of the bottom plate, and the vertical flat side face of the semi-cylindrical plug is fixedly connected with one side face of the bottom plate; the groove is formed in the arc-shaped side face of the semi-cylindrical plug, and the longitudinal axial direction of the groove is the vertical direction; and the rubber water stop plate is arranged in the groove. The connector can effectively prevent water seepage of the diaphragm wall, has better applicability, and is easier to laterally strip and pull out. The invention further provides a circular diaphragm wall construction method, through sequential construction of the first open width, the continuous width and the closed width and combined use of the rotary drill, the trenching machine and the circular drill, soil layer drilling can be effectively carried out, and the overall stability and construction quality in the whole circular diaphragm wall trenching process are guaranteed.
本发明公开了一种圆形地连墙接头，包括多段沿竖直方向固定连接的地连墙接头，每段地连墙接头均包括：底板，其竖直放置；半圆柱体堵头，其高度与所述底板的高度相同，所述半圆柱体堵头的竖直平侧面与所述底板的一侧面固定连接；凹槽，其设置在所述半圆柱体堵头的弧形侧面上，且所述凹槽的纵轴向为竖直方向；橡胶止水板，其设置在所述凹槽中。该接头能够有效地防止地连墙渗水，有更好的适用性，也更容易进行侧向剥离拔除。本发明还提供了一种圆形地连墙施工方法，通过首开幅、连续幅和闭合幅的顺序施工，并利用旋挖钻、成槽机和圆形钻的组合使用，能够有效地进行土层钻进，保证了整个圆形地连墙成槽过程中的整体稳定性和施工质量。
