Method for reinforcing gully through bolting-grouting dam
The invention discloses a method for reinforcing a gully by bolting-grouting dams, which relates to an ecological environment and geological disaster control technology, and mainly adopts the following measures: firstly, arranging a plurality of bolting-grouting dams for intercepting riprap and disintegrating slag according to the natural state of the gully; according to the bolting-grouting dam, two sets of self-drilling type anchor rods are bolted and grouted in a staggered mode in a drilling and grouting mode, the self-drilling type anchor rods drill to the bottom of a gully and enter stable rock at the bottom of the gully to reach a certain anchoring length, then grouting continues to be conducted, and concrete dam bodies anchored to the stable rock at the bottom of the gully one by one are formed to resist gliding of riprap and disintegrating slag; the stability of the gully is ensured; the staggered angle of the two sets of self-drilling type anchor rods on the horizontal plane should meet the requirement that after injected grout is solidified, riprap disintegrating slag of the bolting-grouting dam and the anchor rods form a stable structure, and therefore the purposes of gully governing and slag stabilizing are achieved. According to the method, the working procedures of cleaning filled waste slag, digging out a hard foundation, backfilling after damming and the like are omitted, the construction period is short, and safety is high.
本发明公开一种锚注坝加固冲沟的方法，涉及生态环境和地质灾害治理技术，主要采取以下措施，首先根据冲沟自然状态设置若干用于拦截乱石碎渣的锚注坝。锚注坝是采用边钻进边注浆方式交错锚注两组自钻式锚杆，自钻式锚杆钻至冲沟底部并进入沟底稳定的岩石，达到一定的锚固长度，然后继续注浆，形成一道道锚固于冲沟底部稳定岩体的混凝土坝体，以抵御乱石碎渣的下滑，保证冲沟的稳定性；两组自钻式锚杆在水平面上的交错角度应满足注入的浆液凝固后将该道锚注坝的乱石碎渣和锚杆形成一个稳定的结构，以达到治理冲沟，稳定渣体的目的。本发明方法省去清理已填弃渣、挖出硬地基和筑坝后再进行回填等工序，施工工期短，安全性高。
