System for actively controlling deformation of foundation pit and construction method thereof
The invention relates to a system for actively controlling deformation of a foundation pit and a construction method thereof.The system comprises a foundation pit enclosure wall (1), a grouting device (2), anti-sidesway piles (3) and a barrier reinforcing body (4), the grouting device (2) is arranged on the foundation pit enclosure wall (1), the foundation pit enclosure wall (1) is arranged on the outer side of the foundation pit, and the barrier reinforcing body (4) is arranged on the inner side of the foundation pit. The anti-sidesway piles (3) penetrate through the barrier reinforcing body (4) and are inserted into a soil layer at the lower part of the barrier reinforcing body (4); the barrier reinforcing body (4) comprises a back reinforcing part (41) and a top sealing reinforcing part (42), a gap is reserved between the back reinforcing part (41) and the foundation pit enclosure wall (1), and the top sealing reinforcing part (42) is connected with the foundation pit enclosure wall (1) and the back reinforcing part (41). Compared with the prior art, the grouting technology is utilized in the foundation pit construction period, horizontal extrusion force is provided for the foundation pit enclosure wall, and then horizontal deformation of the wall is actively controlled.
本发明涉及一种主动控制基坑变形的系统及其施工方法，该系统包括基坑围护墙(1)、注浆装置(2)、抗侧移桩(3)和屏障加固体(4)，所述的基坑围护墙(1)上设置注浆装置(2)，所述的基坑围护墙(1)设置于基坑外侧，所述的屏障加固体(4)设置于基坑内侧，所述的抗侧移桩(3)穿过屏障加固体(4)，并插入屏障加固体(4)下部的土层中；所述的屏障加固体(4)包括后靠加固(41)和封顶加固(42)，其中后靠加固(41)与基坑围护墙(1)之间留有空隙，封顶加固(42)连接基坑围护墙(1)和后靠加固(41)。与现有技术相比，本发明在基坑施工期间利用注浆技术，对基坑围护墙提供水平挤压力，进而主动控制墙体水平变形。
