Foundation pit slope protection guniting method
The invention belongs to the technical field of building construction, and particularly relates to a foundation pit slope protection guniting method. The foundation pit slope protection guniting method comprises the following steps that 1, a spray head is inclined by a certain angle relative to a slope protection surface, spraying is carried out by adopting a rotary path, and the lower space of areinforcing mesh is fully filled with cement mortar; and 2, when the thickness of the cement mortar is flush with the reinforcing mesh, the spray head is perpendicular to the slope protection surfaceand carries out spraying along a linear path, wherein in the step 1 and the step 2, a foundation pit slope protection guniting mechanical arm is adopted for carrying out spraying construction, and inthe step 1 and the step 2, a guniting machine is adopted for supplying sand ash to the foundation pit slope protection guniting mechanical arm. According to the foundation pit slope protection guniting method, a spray head mechanism has two states of rotary spraying and vertical spraying, so that the space below the reinforcing mesh is fully filled with the mortar, and spraying is more uniform; and the sand ash is blocked at different heights of a cylinder cavity by using a plurality of layers of partition plates, so that the sand ash can flow towards the downstream more uniformly during spraying, the sand ash is not sprayed towards the downstream in a strand mode, and the guniting uniformity is effectively improved.
本发明属于建筑施工技术领域，具体涉及一种基坑护坡喷浆方法，包括如下步骤：步骤1：先使喷头相对于护坡面倾斜一定角度，并采用回转路径进行喷涂，使水泥砂浆充分填充钢筋网下部空间；步骤2：当水泥砂浆厚度与钢筋网平齐时，再使喷头垂直与护坡面并沿直线路径进行喷涂；所述步骤1、2中，采用基坑护坡喷浆机械手进行喷涂施工；步骤1、2中采用喷浆机对基坑护坡喷浆机械手进行砂灰的供应；本发明的喷头机构具有回旋喷射和垂直喷射两种状态，确保钢筋网下方空间被砂浆充分填充，喷射更均匀。本发明用多层隔板将砂灰阻挡在筒腔的不同高度，这样在进行喷射时砂灰能够更均匀的向下游流动，而不是一股脑的向下游喷出，有效提高了喷浆均匀性。
