Piping repairing device and method for underground diaphragm wall of deep foundation pit
The invention provides a deep foundation pit underground diaphragm wall piping repairing device and method, and belongs to the field of foundation pit construction. In the related technology, a water plugging steel plate is generally arranged on a wall, and the water plugging steel plate and the wall body are poured into a whole, so that seepage repair is realized. However, the risk of failure and relapse is high along with time accumulation. The device comprises a shell assembly, a drill bit assembly and a driving assembly, wherein the drill bit assembly comprises a main drill bit and a self-propelled anchor drill bit. The driving assembly comprises a driving ring, a main drill shaft and an anchor drill shaft, and the anchor drill shaft comprises a flexible shaft section and a guide section. The device is mounted at a pre-drilled hole of a seepage part of a wall body, and in combination with the method, when the driving assembly works, the main drill bit is driven to continuously drill along the hole, and the anchor drill bits laterally drill into a soil layer behind the wall. And then cement paste is injected and diffused along the path of the drill bit to form blocking slurry, and the drill shaft is left in the slurry to form a bearing structure. In general, by adopting the device and the method, the repairing quality is reliable, the durability is high, and relapse is not easy to occur.
本发明提供一种深基坑地下连续墙管涌修复装置及方法，属于基坑施工领域。相关技术中，一般会在墙上设置堵水钢板，将其与墙体浇筑为一体，从而实现渗流修复。但是随着时间的积累，失效和复发的风险高。本装置包括壳体组件、钻头组件和驱动组件，钻头组件包括主钻头和自进式锚钻头。驱动组件包括驱动环、主钻轴和锚钻轴，锚钻轴包括软轴段和导向段。本装置安装于墙体渗流部位的预钻洞口，结合本方法，当驱动组件工作时，带动主钻头沿洞口继续钻入，而多个锚钻头则侧向钻入墙后的土层。接着注入水泥浆，让其沿钻头的路径扩散，形成封堵浆体，钻轴留在浆体中成为承载结构。综合来说，采用本装置及方法修复的质量可靠，耐久度高，不易复发。
