Desert steep slope concrete wet spraying construction process
The invention relates to a desert steep slope concrete wet spraying construction process, and belongs to the technical field of slope protection. The method comprises the following steps that S1, the free face and the slope top face of the desert steep slope are coated with cement paste; s2, after the cement paste is condensed, steel bar meshes are laid according to the shapes and sizes of the free face and the slope top face; the reinforcing meshes are separated from the free face and the slope top face through concrete cushion blocks; s3, concrete is sprayed in a segmented, segmented, blocked and layered mode along the reinforcing mesh from bottom to top through a concrete wet spraying machine, and after condensation, a concrete supporting layer is formed; and S4, after the concrete supporting layer is coagulated for 2 h, maintenance and acceptance are sequentially conducted. The problem that in the prior art, no desert steep slope protection measure aiming at the particularity of the hydrogeological condition of desert sandy soil exists is solved, and the construction technology which is simple in construction procedure, high in mechanization degree, large in construction production capacity, high in production benefit and capable of meeting the desert steep slope requirement can be provided.
本发明涉及一种沙漠陡立边坡混凝土湿喷施工工艺，属于边坡防护技术领域。本发明包括以下步骤：S1、在沙漠陡立边坡的临空面和坡顶面涂刷水泥浆；S2、水泥浆凝结后，根据临空面和坡顶面的形状大小，铺设钢筋网片；将钢筋网片与临空面和坡顶面之间用混凝土垫块隔开；S3、通过混凝土湿喷机沿钢筋网片自下而上地分段、分部、分块、分层喷射混凝土，凝结后，形成混凝土支护层；S4、混凝土支护层凝结2h后，依次进行养护和验收。解决现有技术中存在的“并没有一种针对沙漠砂土的水文地质条件的特殊性的沙漠陡立边坡防护措施”的问题，能够提供一种施工工序简单、机械化程度高、施工生产能力大、生产效益高以及符合沙漠陡立边坡需求的施工工艺。
