System for foundation pit slope protection construction
The invention belongs to the technical field of building construction, and particularly relates to a system for foundation pit slope protection construction. The system comprises a foundation pit slope protection guniting mechanical arm and a guniting machine used for conveying lime-sand mortar to the foundation pit slope protection guniting mechanical arm. A spray head mechanism has two states ofrotary spraying and vertical spraying, mortar can be obliquely sprayed to the area below a reinforcing mesh in the rotary spraying state, it is guaranteed that the space below the reinforcing mesh isfully 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 surface is guaranteed. The lime-sand mortar is blocked at different heights of a barrel cavity through multiple layers of partition plates, so that the lime-sand mortar can flow downstream more uniformly instead of beingsprayed downstream at a time during spraying, 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施工用系统，包括基坑护坡喷浆机械手，以及用于向基坑护坡喷浆机械手输送砂灰的喷浆机；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。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。
