Continuous wall anti-collapse pouring formwork suitable for soft soil area and construction method
The invention relates to a continuous wall anti-collapse pouring formwork suitable for a soft soil area and a construction method, and belongs to the technical field of underground continuous wall construction. The continuous wall anti-collapse pouring formwork comprises a soil facing side supporting plate, a soil backing side supporting plate, an end plate, a bottom supporting plate and a mud discharging pipe, the soil facing side supporting plate, the soil backing side supporting plate, the end plates and the bottom supporting plate define a box-shaped structure with an open top, a mud discharging hole is formed in the bottom supporting plate, the bottom of the mud discharging pipe is inserted into the mud discharging hole, and the top of the mud discharging pipe exceeds the tops of thesoil facing side supporting plate and the soil backing side supporting plate and extends towards the outside of the underground continuous wall groove section. The formwork can effectively prevent wall protection mud from entering the formwork, it is guaranteed that an underground continuous wall is poured in a waterless environment, and mud inclusion during concrete pouring is prevented; a reinforcement cage cannot float upwards due to being lifted by mud when being lowered, so that the concrete pouring quality is ensured; and when underground continuous wall concrete is poured, a guide pipedoes not need to be inserted in advance, the concrete cannot disturb the groove wall, and the groove wall of a soft soil area is effectively prevented from collapsing.
本发明的适用于软土地区的连续墙防坍塌浇筑模板及施工方法属于地下连续墙施工技术领域，包括迎土侧支护板、背土侧支护板、端头板、底部支护板和排泥浆管，迎土侧支护板、背土侧支护板、端头板和底部支护板围合成顶部敞口的箱型结构，底部支护板上开设有排泥浆孔，排泥浆管的底部插入排泥浆孔中，排泥浆管的顶部超出迎土侧支护板和背土侧支护板的顶部并向地下连续墙槽段的外部延伸。该模板可有效防止护壁泥浆进入模板内部，保证地下连续墙在无水环境下浇筑，防止混凝土浇筑时夹泥。钢筋笼下放时不会因为被泥浆托起而上浮，保证混凝土浇筑质量。浇筑地下连续墙混凝土时不需要提前插入导管，且混凝土不会对槽壁造成扰动，有效防止软土地区槽壁坍塌。
