Underground diaphragm wall construction method under low clearance condition
The invention discloses a low-clearance-condition underground diaphragm wall construction method, and relates to the technical field of diaphragm wall construction. The construction method comprises the steps of construction preparation, survey setting-out, guide wall construction, slurry preparation and the like. Through the overall design, the safety performance is high, the stability of the pile foundation is improved by pre-burying the sleeve valve pipes around the viaduct pile foundation for grouting reinforcement, smooth construction of the underground continuous wall is facilitated, economic benefits are excellent, pier settlement is effectively controlled, the labor cost of treatment is saved, the input cost of engineering materials is reduced, and the construction period is shortened. The construction method has the advantages that smooth construction of the underground diaphragm wall on site is guaranteed, the application range is wide, the construction method can be adopted in urban subway underground diaphragm wall construction, pedestrian overpasses, viaducts and other buildings under the low clearance condition, construction can be achieved only by proper construction, and the construction method is simple, high in operability and easy to master by constructors.
本发明公开了一种低净空条件地下连续墙施工工法，涉及连续墙施工技术领域。本发明包括：施工准备、测量放样、导墙施工、泥浆制备等步骤。本发明通过整体的设计，安全性能高，通过沿高架桥桩基周围预埋袖阀管注浆加固来提高桩基的稳定性，有利于地下连续墙顺利施工，经济效益优，桥墩沉降的有效控制，既节省了处理的人工费用，又减少了工程材料的投入成本，确保了现场地下连续墙施工的顺利进行，适用范围广，在城市地铁地下连续墙施工中，人行天桥、高架桥和其他建筑低净空条件下都能采用，只需施工得当，均能实现，施工方法简单，操作性强，施工人员易于掌握。
