The invention discloses a broken line type underground diaphragm wall section joint construction method, and relates to the technical field of underground diaphragm wall construction processes. Comprising the following steps that after a first-stage groove is formed, a drawable occupied pipe fitting is arranged at the end, connected with a second-stage groove, of the first-stage groove; a milling pipe fitting is embedded in the end, right opposite to the occupied pipe fitting, of a first-stage reinforcement cage, and the first-stage reinforcement cage is arranged in the first-stage groove; concrete of the first-stage groove is poured, and after the concrete in the first-stage groove reaches the preset strength, the occupied pipe fitting is pulled out; and a second-stage groove is dug, and concrete of the millable pipe fitting and the occupied pipe fitting is milled off. According to the method, the usage amount of concrete during first-stage groove pouring can be effectively reduced, the milling amount of concrete for second-stage groove forming can be effectively reduced, the risk of pulling out occupied pipe fittings and the requirement for pipe drawing bench equipment can be effectively reduced, and the requirement for building an underground diaphragm wall trunk in a region lacking manpower resources is met.
本发明公开了一种折线型地连墙墙段接头施工方法，涉及地下连续墙施工工艺技术领域；包括以下步骤：在一期槽成槽后，在所述一期槽与二期槽连接的一端下设可拔出的占位管件；在一期钢筋笼正对所述占位管件的一端内嵌可铣削管件，并将所述一期钢筋笼下设在所述一期槽内；浇注所述一期槽的混凝土，并在所述一期槽内的混凝土达到预设强度后，拔出所述占位管件；挖设二期槽，并铣削掉所述可铣削管件和所述占位管件部位的混凝土。本发明能有效的减少一期槽浇筑时混凝土的使用量、有效的减少二期槽成槽的混凝土铣削量，能够有效的减小占位管件起拔的风险和对拔管机设备的要求，满足在人力资源缺乏的地区筑设地连墙围井的需求。
