Foundation pit enclosure structure, enclosure system and enclosure method for vertical shaft construction
The invention relates to a foundation pit enclosure structure, an enclosure system and an enclosure method for vertical shaft construction. The foundation pit enclosure structure for vertical shaft construction is provided with foundation pit continuous walls anchored into the ground, the foundation pit continuous walls are connected end to end, an area defined by the foundation pit continuous walls is a construction area, excavation is conducted in the construction area to form a foundation pit, and cast-in-place piles are driven into the positions, close to the foundation pit continuous walls, in the foundation pit in the arrangement direction of the foundation pit continuous walls. A concrete bottom plate is poured on the foundation pit ground close to the foundation pit continuous wall, a concrete retaining wall arranged in the arrangement direction of the foundation pit continuous wall is poured on the concrete bottom plate, and the space between the concrete retaining wall and the foundation pit continuous wall is filled with rock ballast. Thus, after the foundation pit continuous wall is anchored into the ground around the foundation pit, the foundation pit continuous wall is well supported by arranging the cast-in-place piles, the concrete bottom plate and the concrete retaining wall which are fixed together and the rock ballast body filled between the concrete retaining wall and the foundation pit continuous wall, and the structural strength of the foundation pit support is enhanced.
本发明涉及一种竖井施工的基坑围护结构及围护系统及围护方法。其中一种竖井施工的基坑围护结构具有锚入至地面内的基坑连续墙，基坑连续墙首尾连接，基坑连续墙围成的区域为施工区域，在施工区域内开挖形成基坑，在基坑内靠近基坑连续墙的位置处沿基坑连续墙的布置方向打入灌注桩，在靠近基坑连续墙的基坑地面上浇筑有混凝土底板，在混凝土底板上浇筑有沿基坑连续墙布置方向布置的混凝土挡墙，在混凝土挡墙与基坑连续墙之间填充石渣体。如此，在将基坑连续墙锚入基坑周围地面内后，通过设置固定在一起的灌注桩、混凝土底板、混凝土挡墙及填充在混凝土挡墙与基坑连续墙之间的石渣体，对基坑连续墙起到了良好的支护作用，增强了基坑围护的结构强度。
