Title:
GROUT INJECTION POSITIONING ANCHOR ROD SUITABLE FOR USE IN SEEPAGE FAILURE PREVENTION IN ENGINEERING PROJECT, AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/042090
Kind Code:
A1
Abstract:
Disclosed is a grout injection positioning anchor rod suitable for use in seepage failure prevention in an engineering project, the grout injection positioning anchor rod comprising an anchor rod (1), a grout injection guide pipe (2) and a grout injection pipe (3); when there is a seepage failure in an engineering project, a water pump can be connected to a drainage pipe connector to achieve water drainage, while also utilizing a limiter to conduct grout injection positioning on a seepage failure area, such that grout injection reinforcement accuracy is improved; a drainage channel and a grout injection channel are independent from one another and do not interfere with one another, and the original support function of the anchor rod is maintained while drainage and grout injection functions are integrated. Thus, the purpose of efficiently preventing and addressing seepage failure in engineering projects is achieved, and construction costs and construction time are saved. Also disclosed is a construction method using the grout injection positioning anchor rod.
