Construction method for underground diaphragm wall in underground air-raid shelter area
The invention discloses a construction method for an underground diaphragm wall in an underground air-raid shelter area, and belongs to the technical field of engineering construction. The method comprises the following steps: S1, ascertaining an underground air-raid shelter; S2, plugging: plugging the a roadway according to the layout of the underground air-raid shelter so as to block a main tunnel and the roadway; S3, backfilling: backfilling an air-raid shelter body with concrete to enable the space of a main cave to form an entity; S4, hole guiding: adopting a rotary drilling rig for conducting hole guiding on the air-raid shelter; S5, grooving: conducting rock drilling grooving through double-wheel milling equipment; S6, checking whether a groove section meets the design requirement or not, if yes, executing the step S7, and if not, executing the step S5; S7, manufacturing a reinforcement cage in the first step and placing the reinforcement cage in the second step; and S8, pouringconcrete to form a groove. According to the method, the comprehensive grooving construction method of blocking, filling, drilling and milling is adopted for the underground diaphragm wall in an existing underground air-raid shelter area, through blocking of the roadway, the construction safety and reliability are improved, wall protecting and grooving can be achieved, the construction difficultyis reduced, and the construction quality is improved.
本发明公开了一种地下防空洞区域地下连续墙施工方法，属于工程施工技术领域，该方法包括以下步骤：S1、探明地下防空洞；S2、封堵：根据地下防空洞的布局，封堵巷道，以将主洞和巷道阻断；S3、回填：采用混凝土对防空洞体进行回填，使主洞空间形成实体；S4、引孔：采用旋挖钻机对防空洞进行引孔；S5、成槽：采用双轮铣设备凿岩成槽；S6、检验槽段是否满足设计要求，若满足，则跳转S7②，若不满足，则跳转S5；S7、进行钢筋笼的①制作和②安放；S8、灌注混凝土成槽。在本发明中，该方法在既有地下防空洞区地下连续墙采用堵、填、钻、铣的综合成槽施工方法，且通过巷道的封堵，提高施工安全性、可靠性、能够护壁成槽，降低施工难度，提高施工质量。
