Subway station cover and excavation top-down structure and construction method
The invention relates to the technical field of underground building structures, in particular to a subway station cover-excavation top-down construction structure and a construction method.The subway station cover-excavation top-down construction structure comprises a foundation pit, a cover plate is arranged at the top of the foundation pit, a plurality of fender posts evenly distributed in the front-back direction are arranged on the left side and the right side of the cover plate correspondingly, and a concave groove is formed in the lower end of each fender post; a plurality of concave grooves are formed in the base, a second spherical body is arranged in each concave groove, a plurality of middle vertical piles are arranged in the middle of the cover plate, a first spherical body is arranged at the lower end of each middle vertical pile, when an earthquake occurs, impact in different directions can be transmitted to the base, meanwhile, the damping mechanism buffers the base, further shaking of the base is reduced, and the shock absorption effect of the base is improved. When the bottom soil layer settles, the second spherical body rolls on the arc-shaped slide way under the action of the base and the second spherical body, so that the second spherical body is still located at the horizontal position, it is guaranteed that the station body does not incline, and wide application prospects are achieved in the technical field of underground building structures.
本发明涉及地下建筑结构技术领域，尤其是一种地铁车站盖挖逆作结构及施工方法，包括基坑，其中，所述基坑的顶部设置为盖板，所述盖板的左右两侧分别设置有若干个沿前后方向均布的围护桩，每个所述围护桩的下端均设置有凹形槽，每个所述凹形槽内均设置有第二球形体，所述盖板的中部设置有若干个中立桩，每个所述中立桩的下端均设置有第一球形体，在发生地震活动时，不同方向的冲击会传递给底座，同时减震机构对底座进行缓冲，减少底座发生进一步晃动，在底部土层发生沉降时，在底座以及第二球形体的作用下，第二球形体在弧形滑道上发生滚动，使其仍然处于水平位置，保证了车站主体不发生倾斜，在地下建筑结构技术领域有着广泛的应用前景。
