Anchoring force enhanced full-bonding steel pipe anchor rod with pneumatic nailing function and mounting method thereof

HUANG DA / ZHENG YI / PENG JIANBING / SHEN YANJUN

The invention discloses an anchoring force enhanced full-bonding steel pipe anchor rod with pneumatic nailing and a mounting method thereof, the steel pipe anchor rod is pushed into the inner wall of a loess anchoring hole by utilizing an air bag through a telescopic conical grouting nail, and finally concrete slurry is fully permeated into a soil body around the steel pipe anchor rod through a hollow pipe body system, so that the anchoring force enhanced full-bonding steel pipe anchor rod is formed. And finally, the steel pipe concrete soil body reinforcing and supporting structure with the multiple branches is formed. By means of the design of the telescopic conical grouting nails, the anchor rod can be installed in a small anchoring hole, the grouting range of the grouting anchor rod is increased through extrusion of the conical grouting nails, the cohesive force of the grouting body after solidification is increased, and then the loess reinforcing effect is improved. The mounting method of the steel pipe anchor rod is simple, and the bonding capacity and the pulling resistance of the mounted steel pipe anchor rod and the grouting body are improved.

本发明公开气压入钉的锚固力增强型全粘结钢管锚杆及其安装方法，该钢管锚杆通过可伸缩式的锥形注浆钉，利用气囊将其推入黄土锚固孔内壁中，最后通过中空的管体系统，使混泥土浆料充分渗透到钢管锚杆周边的土体中，最终形成带有多个分支的钢管混泥土的土体加固支撑结构。可伸缩式的锥形注浆钉的设计，可实现在较小的锚固孔内实现锚杆的安装，锥形注浆钉的挤出增加了该注浆锚杆的注浆范围和注浆体固化后的粘聚力，进而提高对黄土的加固作用。该钢管锚杆的安装方法简单，安装完成后的钢管锚杆与注浆体的粘结能力和抗拔能力。
