Grouting anchor rod construction process for side slope shallow layer support
The invention discloses a grouting anchor rod construction process for side slope shallow layer supporting, and relates to the technical field of side slope supporting. Comprising the following steps that S1, construction preparation is conducted, and materials and equipment used for construction are all on site; s2, drilling is conducted, and during drilling, the hole position deviation, the drilling inclination angle, the direction angle error and the hole depth of an anchor rod hole should be strictly controlled; s3, hole cleaning is conducted, specifically, hole channels are cleaned up through pressure air; s4, anchor rod hole grouting is conducted, specifically, a grouting pipe is inserted into the bottom of the hole and then retreats for 5-10 cm, grouting is started, the grouting pipe is slowly pulled out at a constant speed along with mortar injection, and the hole is filled with mortar; s5, anchor rods are installed, and anchor rod bodies are inserted in time after anchor rod holes are filled with mortar; and S6, checking and accepting the constructed anchor rod by the quality inspection personnel and the supervision engineer. The construction process provided by the invention not only has the characteristics of high construction speed and high detection qualification rate, but also has a good effect of reinforcing the slope rock-soil body, and can provide enough tensile force to meet engineering requirements.
本发明公开了一种用于边坡浅层支护的注浆锚杆施工工艺，涉及边坡支护技术领域。包括以下步骤：S1：施工准备，施工所用材料、设备均到场；S2：钻孔，钻孔时应严格控制锚杆孔孔位偏差、钻孔倾角、方向角误差、孔深；S3：清孔，用压力风将孔道清洗干净；S4：锚杆孔注浆，注浆管应插到孔底，然后退出5cm～10cm开始注浆，注浆管随砂浆的注入缓慢匀速拔出，使孔内填满砂浆；S5：安装锚杆，锚杆孔灌满砂浆后及时插入锚杆体；S6：质检人员和监理工程师对所施工锚杆进行验收。本发明提供的施工工艺不仅具有施工速度快，检测合格率高的特点，且加固边坡岩土体作用良好，能够提供足够的拉力，满足工程要求。
