Grouting anchor rod construction process for supporting side slope
The invention provides a grouting anchor rod construction process for supporting a side slope. The grouting anchor rod construction process comprises the following steps that an anchor hole is drilled in the slope surface of the side slope, all sundries in the anchor hole are removed, and the anchor hole is divided into a front section and a rear section; a grouting pipe extends into the anchor hole; cement paste is injected into the anchor hole through the grouting pipe, and after the front section is filled with the cement paste, the grouting pipe is pulled out at a constant speed while the cement paste continues to be injected; and after an anchor rod is inserted into the anchor hole, a tray sleeves the anchor rod, a locking nut is screwed, and the tray covers the hole opening of the anchor hole. According to the technical scheme of the grouting anchor rod construction process for supporting the side slope, the anchor hole is divided into the two ends to be grouted in sequence, the grouting pipe is pulled out at the constant speed while the rear section is grouted, cement paste can be filled more compactly, the anchor rod supporting strength is improved, and potential safety hazards are reduced; and the waterproof performance of the cement paste is improved by selecting the reasonable water cement ratio, groundwater is prevented from permeating into the cement paste, and the supporting effect is improved.
本发明提供一种用于支护边坡的注浆锚杆施工工艺，包括以下步骤：在边坡坡面上钻取锚孔，清除锚孔内所有杂物，将锚孔划分为前工段、后工段；将注浆管伸入锚孔内；使水泥浆经过注浆管注入锚孔内，待水泥浆充满前工段后，继续注入水泥浆的同时匀速拔出注浆管；将锚杆插入锚孔内后，在锚杆上套装有托盘、螺接锁紧螺母，使托盘盖合在锚孔孔口处。采用本发明的技术方案，通过将锚孔划分为两端先后注浆，并且在对后段注浆的同时匀速拔出注浆管，使水泥浆能够填充更密实，提升了锚杆支护强度，减少了安全隐患，通过选用合理的水灰比，增加了水泥浆的防水性能，防止地下水渗入水泥浆，提升了支护效果。
