Underground diaphragm wall post-holing pre-reinforcement construction method and underground diaphragm wall constructed by underground diaphragm wall post-holing pre-reinforcement construction method
The invention discloses a post-holing pre-reinforcement construction method for an underground diaphragm wall and the underground diaphragm wall constructed by the post-holing pre-reinforcement construction method, and the underground diaphragm wall is obtained by performing grooving operation at the position of the underground diaphragm wall; pre-reinforced beam steel bars are placed in the underground diaphragm wall steel reinforcement cage; then, an underground diaphragm wall reinforcement cage is placed in the underground diaphragm wall groove section, and concrete is poured into the underground diaphragm wall groove section; the method comprises the following steps: firstly, chiseling hole diaphragm walls on the two sides of a framing position before punching, connecting the hole diaphragm walls on the two sides of the framing position through pre-reinforced beam main reinforcements after chiseling is completed, binding pre-reinforced beam stirrups and arranging pre-reinforced beam bent reinforcements, and pouring concrete; and after the concrete strength of the hole diaphragm walls on the two sides of the framing position reaches a design value, large-surface holing construction is conducted. According to the underground diaphragm wall constructed through the method, the defects that in a traditional underground diaphragm wall rear holing method, due to the fact that a top frame is returned, a reinforcing beam is difficult to construct, and water leakage is extremely likely to be caused are overcome.
本发明公开了一种地连墙后开洞预加固施工方法及其构建的地连墙，通过在地连墙位置处实施成槽作业，成槽得到地下连续墙；在地连墙钢筋笼中放置预加固梁钢筋；接着将地连墙钢筋笼放置到地连墙槽段槽段内，并将混凝土灌注入地连墙槽段中；开洞前首先对分幅位置两侧的洞口地连墙进行打凿，完成打凿后，将分幅位置两侧的洞口地连墙间通过预加固梁主筋连接，并完成预加固梁箍筋的绑扎和预加固梁弯起钢筋的设置，并混凝土浇筑；在分幅位置两侧的洞口地连墙混凝土强度达到设计值后大面开洞施工。通过上述方法构建的地连墙传统地连墙后开洞方法中因回顶架的原因导致加固梁施工困难，且极易造成渗漏水的缺点。
