Casing anchoring method, carrier and casing anchoring assembly

ZENG QINGYI

The casing anchor inserting method comprises the steps of constructing the casing anchor inserting assembly part, hoisting the casing anchor inserting assembly part, disconnecting movable connection, driving the casing anchor inserting assembly part into a stratum, pulling out a casing, grouting and the like, and the invention further provides the bearing body for casing anchor inserting and the casing anchor inserting assembly part. The pressure type anchor rod has the main advantages that the area of the bearing body reaches the maximum, the pulling resistance of the pressure type anchor rod is improved, meanwhile, the problem that the bearing body is prone to deviation and deflection in an anchor hole is solved, and adverse effects on the pulling resistance and reliability are avoided.

本发明提供的套管插锚方法，包括构建套管插锚组装件、吊装套管插锚组装件、活动连接脱开、套管插锚组装件打入地层、拔出套管及注浆等步骤，本发明还提供了用于套管插锚的承载体及套管插锚组装件。本发明的主要优点是承载体面积达到最大，提高了压力型锚杆的抗拔力，同时还解决了承载体在锚孔中易偏位和偏转的问题，避免了对抗拔力及可靠性的不良影响。
