Fabricated prefabricated underground retaining wall using underground diaphragm wall excavation system and construction method of fabricated prefabricated underground retaining wall
The invention discloses an assembly type prefabricated underground retaining wall using an underground diaphragm wall excavation system and a construction method of the assembly type prefabricated underground retaining wall. The method comprises the following steps that (1) the underground diaphragm wall excavation system is installed; (2) a groove is excavated, the designed number of rectangular assembly type underground retaining walls and the designed number of L-shaped assembly type underground retaining walls sink into the groove and are well spliced, and the whole retaining wall is formed; (3) concrete is poured between the whole retaining wall and the soil body on the outer side of the retaining wall, and concrete is poured into the concrete pouring groove I and the concrete pouring groove II; (4) a soil body on the inner side of the whole retaining wall is excavated, anchor rods are driven into the reserved anchor rod holes I and the reserved anchor rod holes II from top to bottom, the anchor rods are driven into the soil body on the outer side of the whole retaining wall, the anchor rods are anchored and welded, and concrete is poured into anchor rod concrete pouring grooves I and anchor rod concrete pouring grooves II; and (5) the step (4) is repeated till the excavation depth of the inner side of the whole retaining wall meets the design requirement.
本发明公开了一种使用地下连续墙开挖系统的装配式预制地下挡墙及其施工方法，该方法包括以下步骤：1)安装地下连续墙开挖系统；2)开挖沟槽，将设计数量的矩形装配式地下挡墙和L型装配式地下挡墙下沉至沟槽内并拼接好，形成挡墙整体；3)在挡墙整体与其外侧的土体之间浇筑混凝土，向混凝土浇筑槽Ⅰ和混凝土浇筑槽Ⅱ内浇筑混凝土；4)开挖挡墙整体内侧的土体，按照从上到下的顺序，向预留锚杆孔Ⅰ和预留锚杆孔Ⅱ打入锚杆，锚杆打入挡墙整体外侧的土体内，并对锚杆锚固焊接，向锚杆混凝土浇筑槽Ⅰ和锚杆混凝土浇筑槽Ⅱ内浇筑混凝土；5)重复步骤4)，直到挡墙整体内侧的开挖深度满足设计要求。
