Enclosure structure capable of actively controlling deformation and construction method thereof
The invention relates to an enclosure structure capable of actively controlling deformation and a construction method thereof.The enclosure structure comprises a foundation pit enclosure wall (1), lateral grouting pipes (2) and a rigid barrier (6), the lateral grouting pipes (2) are arranged in the foundation pit enclosure wall (1), the foundation pit enclosure wall (1) is arranged on the outer side of a foundation pit, and the rigid barrier (6) is arranged in the foundation pit enclosure wall (1). The rigid barrier (6) is parallel to the foundation pit enclosure wall (1) and is arranged in a soil body on the inner side of a foundation pit; the lateral grouting pipe (2) is a hollow circular steel pipe which is arranged in an L shape; the upper ends of the lateral grouting pipes (2) are located at the top end of the foundation pit enclosure wall (1), and the lower ends of the lateral grouting pipes (2) are located on the inner side wall of the foundation pit enclosure wall (1). The lower end of the lateral grouting pipe (2) is externally connected with bag-shaped geotechnical cloth (4); and the lateral grouting pipe (2) is fixed on the vertical steel truss (5). 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变形的围护结构及其施工方法，该围护结构包括基坑围护墙(1)、侧向注浆管(2)和刚性屏障(6)，所述基坑围护墙(1)的内部设置侧向注浆管(2)，所述的基坑围护墙(1)设置于基坑外侧，所述的刚性屏障(6)平行基坑围护墙(1)设置于基坑内侧的土体中；所述的侧向注浆管(2)为L型布置的中空圆钢管；所述侧向注浆管(2)的上端位于基坑围护墙(1)的顶端，下端位于基坑围护墙(1)的内侧壁；所述侧向注浆管(2)的下端外接袋状土工布(4)；所述的侧向注浆管(2)固定在竖向钢桁架(5)上。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。
