Construction method of soil nailing wall supporting structure
The invention discloses a construction method of a soil nailing wall supporting structure, which belongs to the technical field of construction, and comprises the following steps: ensuring that the position of a side slope and the gradient of a slope are accurate, confirming a hole position and constructing marks, and excavating the side slope in front of the wall from top to bottom in a layered manner; after slope excavation is completed, a first layer of reinforcing mesh is installed, and concrete with the same grade as formwork concrete is sprayed in the same layer; after concrete spraying is completed, soil nails are installed according to the drawing requirements, meanwhile, drainage hole construction within the range of the layer is conducted, in a section where a soil nail wall or an inter-pile soil nail wall is adopted, locking and jacking anchor rods are constructed according to the design requirements, and after construction is completed, an anti-pulling test is conducted on the soil nails; the guide pipe is slowly withdrawn at a constant speed during grouting, and a grouting guide pipe opening is always buried below the surface of the slurry in the grouting process; and after grouting is completed, a second layer of reinforcing mesh is installed, and formwork concrete pouring is conducted after installation is completed. The supporting device is easy to operate, and the supporting strength of the soil nailing wall can be further improved.
本发明公开了一种土钉墙支护结构的施工方法，属于施工技术领域，包括：确保边坡位置及放坡坡度准确，确认孔位并施工标记，从上至下分层开挖墙前边坡；坡面开挖完成之后进行第一层钢筋网片安装，在同一分层内先喷射与支模混凝土等级相同的混凝土；待喷射混凝土完成后按图纸要求进行土钉安装，同时进行本层范围内的泄水孔施工，在采用土钉墙或桩间土钉墙地段，按设计要求先施工锁顶锚杆，施工完成后针对土钉进行抗拔测试；在注浆同时将导管匀速缓慢地撤出，注浆过程中注浆导管口应始终埋在浆体表面以下；注浆完成后进行第二层钢筋网片安装，安装完毕之后进行支模混凝土浇筑。本发明一种操作简单且能够进一步提高土钉墙的支护强度。
