かかる、現状に鑑みて地盤補強用のロックボルトを利用
して水抜きも行うことが望まれていた。In view of the current situation, it has been desired to drain water using rock bolts for ground reinforcement.
（課題を解決するための手段）
本発明は前記要望に応えてなされたもので、その発明は
透水壁で構成される中空管から成るロックボルトを要旨
とする。(Means for Solving the Problems) The present invention has been made in response to the above-mentioned needs, and its gist is a rock bolt made of a hollow tube made of a water-permeable wall.
透水壁は、中空管自体を金属、セラミック等の焼結多孔
質体等の透水性材料で構成してもよいが、金属、プラス
チック等の非透水性材料でできた中空管の壁体に貫通孔
を穿設するようにして構成してもよい。The permeable wall may be made of a permeable material such as a sintered porous material such as metal or ceramic, but the wall of the hollow pipe may be made of a non-permeable material such as metal or plastic. It may also be configured such that a through hole is provided in the hole.
また、透水壁の外周面に透水性を損なわないようにして
補強繊維を結着して粗面とし、ロックボルトの付着力を
大きくしてもよい。Further, reinforcing fibers may be bound to the outer circumferential surface of the water-permeable wall to make the surface rough without impairing water permeability, thereby increasing the adhesion force of the rock bolt.
（作 用）
中空管の強度により地盤は補強され、該中空管の透水壁
を介して地盤中の水は中空管内に集水され、集水された
水は該中空管の端部開口から排出され水抜きされる。(Function) The ground is reinforced by the strength of the hollow pipe, water in the ground is collected into the hollow pipe through the permeable wall of the hollow pipe, and the collected water is collected at the end of the hollow pipe. The water is drained through the opening.
