Foundation pit water stop supporting device and dewatering construction method thereof
The invention relates to a foundation pit water-stop supporting device and a dewatering construction method thereof. The foundation pit water-stop supporting device comprises front-row supporting cast-in-place piles, front-row plain concrete piles, rear-row supporting cast-in-place piles, a vertical shear wall, a top beam, a connecting beam and a concrete pressing top plate. The front-row supporting cast-in-place piles and the front-row plain concrete piles are meshed with each other. Reinforcing vertical shear walls are arranged between the front-row cast-in-place piles and the rear-row cast-in-place piles A top beam and a concrete pressing top plate are arranged at the tops of the double-row piles, so that the front-row supporting cast-in-place piles and the rear-row supporting cast-in-place piles are connected into Therefore, the double-row piles form a whole, the supporting rigidity is further improved, the horizontal displacement of the foundation pit is reduced, and the stability of the foundation pit is improved; according to the novel box-type reinforced double-row piles, the lateral rigidity of the whole supporting structure is improved, the bending resistance, the overturning resistance and the capacity of resisting the pressure of water and soil on the outer side of a pit of the supporting structure are enhanced, and therefore deformation of the foundation pit is effectively controlled; and a lateral support and an anchor pulling system do not need to be arranged.
本发明涉及一种基坑止水支护装置及其降水施工方法，包括前排支护灌注桩、前排素混凝土桩、后排支护灌注桩、垂直剪力墙、冠梁、连梁、混凝土压顶板前排支护灌注桩与前排素混凝土桩互相咬合，前排灌注桩与后排灌注桩之间间隔设置加强垂直剪力墙；双排桩顶部设置冠梁、混凝土压顶板，使前排支护灌注桩与后排支护灌注桩连成整体；从而使双排桩形成整体，进一步增加支护刚度，减小基坑的水平位移，提高基坑稳定性；本发明新型箱式加强双排桩提高了支护结构整体的侧向刚度，增强了支护结构的抗弯、抗倾覆及抵抗坑外侧水土压力的能力，从而效控制基坑变形；无需设置侧向支撑和拉锚体系。
