Foundation pit slope protection construction method
The invention belongs to the technical field of building construction, and particularly relates to a foundation pit slope protection construction method. The method comprises the following steps that1, a foundation pit slope protection face is trimmed through an excavator; 2, holes are drilled in the slope protection face, and drainage pipes and anchor rods perpendicular to the slope protection face are pre-buried; 3, a reinforcing mesh is laid and bound on the slope protection face, and joints, close to the anchor rods, of the reinforcing mesh are welded and fixed to the anchor rods; and 4,cement mortar is sprayed to the slope protection face. A spray head mechanism has two states of rotary spraying and vertical spraying, mortar can be obliquely sprayed to the area below the reinforcingmesh in the rotary spraying state, it is guaranteed that the space below the reinforcing mesh is fully filled with the mortar, the surface of the mortar can be trimmed in the vertical spraying state,spraying is more uniform, and the surface flatness of the slope protection face is guaranteed.
本发明属于建筑施工技术领域，具体涉及一种基坑护坡施工方法，包括如下步骤：步骤1：用于挖掘机修整基坑护坡面；步骤2：在护坡面上钻孔并预埋排水管和垂直于护坡面的锚杆；步骤3：在护坡面上铺设、绑扎钢筋网，将钢筋网靠近锚杆处的结点与锚杆焊接固定；步骤4：对护坡面喷射水泥砂浆；本发明的喷头机构具有回旋喷射和垂直喷射两种状态，回旋喷射状态下砂浆能够斜向喷涂到钢筋网下方的区域，确保钢筋网下方空间被砂浆充分填充，而垂直喷射状态下能够对砂浆表面进行修整，喷射更均匀，确保护坡面表面平整度。
