Underground diaphragm wall joint construction method
The invention belongs to the technical field of building construction, and discloses an underground diaphragm wall joint construction method which comprises the following steps: prefabricating a plurality of underground diaphragm wall sections and excavating groove sections; slurry is injected into the groove sections, then the multiple underground diaphragm wall sections are lowered into the groove sections at intervals, and a cavity is formed between every two adjacent underground diaphragm wall sections; concrete is poured into the cavity, and curing is carried out; and a foundation pit is excavated on one side of the prefabricated underground diaphragm wall section, and in the foundation pit excavation process, concrete in a cavity close to one side of the foundation pit is chiseled to form a groove. According to the underground diaphragm wall joint construction method, the requirement for construction precision is low, and the construction difficulty is low; and the embedded columns can enhance the connection strength between the adjacent underground diaphragm wall sections, resist the soil pressure on the opposite side of the foundation pit, improve the shear capacity of the underground diaphragm wall and protect the underground diaphragm wall from being damaged.
本发明属于建筑施工技术领域，公开了一种地下连续墙接头施工方法，其中包括以下步骤：预制多个地下连续墙段以及开挖槽段；在槽段中注入泥浆，然后将多个地下连续墙段间隔下放至槽段中，以在相邻两个地下连续墙段间形成空腔；在空腔中浇筑混凝土，并进行养护；在预制地下连续墙段的一侧开挖基坑，并在开挖基坑的过程中，将靠近基坑一侧的空腔中的混凝土凿除以形成凹槽。本发明提供的地下连续墙接头施工方法，对施工的精度要求小，施工难度低；且具有较好的连接强度，密封效果较好，有效防止水的渗入，暗柱可加强相邻地下连续墙段之间的连接强度，抵抗基坑相对一侧的土压力，提高地下连续墙的抗剪能力，保护地下连续墙不被破坏。
