Graded grouting anchor cable and construction method
The invention discloses a graded grouting anchor cable and a construction method, and belongs to the technical field of geotechnical engineering. The anchor cable is composed of a plurality of grouting units, and each grouting unit comprises a grouting pipe, a pressing plate, a connecting plate, an annular high-pressure plugging air bag, an air conveying pipe, a water pressure balance pipe, a connecting pipe and a one-way valve. Meanwhile, the invention discloses a construction method of the graded grouting anchor cable, the anchor cable is divided into a plurality of grouting areas by arranging the grouting units at different positions of the anchor cable and controlling the opening pressure of all the one-way valves, and graded grouting of the anchor cable is achieved by adopting the mode that grouting is conducted from the hole top to the hole bottom. The problems of grout mixing, grout leakage, excess, pressure failure and the like are effectively avoided, fixed-point quantitative grouting of the rock-soil body is achieved, the anchor cable grouting quality is improved, grouting materials are saved, and economic benefits are remarkable.
本发明公开了一种分级注浆锚索及施工方法，属于岩土工程技术领域。该锚索由若干注浆单元组成，每个注浆单元包括注浆管、压板、连接板、环形高压封堵气囊、输气管、水压平衡管、连接管和单向阀。同时本发明公开了一种分级注浆锚索的施工方法，通过在锚索不同位置处设置注浆单元，并控制各单向阀开启压力大小，将锚索分为若干注浆区，采用孔顶向孔底注浆方式，实现了锚索分级注浆。该发明有效避免了浆液串浆、漏浆、超量、压力上不来等问题，实现了岩土体定点定量注浆，不仅提高了锚索注浆质量，还节约了注浆材料，经济效益显著。
