Construction method of underground diaphragm wall capable of actively blocking water
The invention provides a construction method of an underground diaphragm wall with an active water blocking function. The construction method comprises the following steps that S1, the construction sequence and construction indexes of the underground diaphragm wall on the outer side of a to-be-excavated area are determined according to a design drawing; s2, the underground diaphragm wall is excavated to the designed depth; s3, a reinforcement cage is bound outside the diaphragm wall, and a guide pipe penetrates through the middle of the reinforcement cage; s4, the reinforcement cage and the guide pipe in the S3 are integrally placed into the underground diaphragm wall; s5, concrete pouring is conducted on the underground diaphragm wall; s6, after the concrete reaches the strength, post-construction precipitation well drilling construction is conducted; s7, the hole forming equipment penetrates through the guide pipe in the reinforcement cage, and continuously drills into the soil body boundary layer after completely penetrating through the guide pipe; s8, after the slag removal operation, a water suction pump is installed in the post-operation dewatering well to pump water; s9, the foundation pit is excavated till the designed depth is reached; and S10, the state of the foundation pit is checked, concrete is poured at the bottom of the foundation pit to form a sealing bottom, and the guide pipe is poured and filled. The method is ingenious in design and wide in application range, and has good economic benefits.
本发明提供一种主动阻水的地下连续墙的施工方法，包括以下步骤：S1、根据设计图纸确定待挖区外侧的地连墙的施工顺序和施工指标；S2、对地连墙进行开挖至设计深度；S3、在地连墙的外部绑扎钢筋笼，并将导管穿过钢筋笼的中部；S4、将S3中的钢筋笼和导管整体放入地连墙中；S5、对地连墙进行浇筑混凝土；S6、待混凝土达到强度后，进行后作降水井钻孔施工；S7、成孔设备穿过钢筋笼中的导管，并在完全贯穿导管后继续钻进至土体分界层；S8、清渣作业后，后作降水井内安装抽水泵抽水；S9、开挖基坑，直至设计深度；S10、检查基坑的状态，在基坑的底部浇筑混凝土形成封底，并对导管进行浇筑填充。本发明设计巧妙，适用范围广，具有良好的经济效益。
