Slope excavation supporting structure and construction method
The invention discloses a slope excavation supporting structure and a construction method. The slope excavation supporting structure comprises anchor rods, wherein each anchor rod comprises an outer pipe, two inner rods and reinforcing blocks, the inner rods are slidably connected to the outer pipes, sliding grooves are formed in the outer pipes, the inner rods are located in the sliding grooves,the top ends of the inner rods extend out of the sliding grooves, the reinforcing blocks are fixedly connected to the bottoms of the inner rods, the reinforcing blocks are slidably connected to the outer pipes, containing grooves are formed in the outer pipes, the reinforcing blocks are located in the containing grooves, anchoring holes matched with the anchor rods are formed in the side slope, the anchor rods are inserted into the anchoring holes, one ends of the anchor rods extend out of the surface of the side slope, a plurality of anchor rods are arranged, and a concrete layer is sprayed to the surface of the side slope. The construction method of the slope excavation supporting structure comprises the steps that S1, blasting is conducted according to a drawing; S2, deslagging and preliminary supporting are conducted according to the layer of 3 meters; and S3, a protection plate is installed, and the concrete layer is sprayed. According to the slope excavation supporting structureand a construction method, the effect of strengthening the anchoring force of the anchor rods and the slope is achieved.
本申请涉及一种边坡开挖支护结构及施工方法，边坡开挖支护结构包括锚杆，锚杆包括外管、内杆、加强块，内杆滑动连接于外管，外管内开设有滑槽，内杆位于滑槽内，且内杆顶端伸出滑槽外，内杆设置有两根，加强块固定连接于内杆底部，加强块滑动连接于外管，外管内开设有容置槽，加强块位于容重槽内，边坡上开设有与锚杆适配的锚固孔，锚杆插设于锚固孔内，锚杆一端伸出边坡表面，锚杆设置有多根，边坡表面喷射有混凝土层，边坡开挖支护结构的施工方法为：S1、根据图纸进行爆破；S2、按照3m一层进行出渣与初步支护；S3、进行防护板的安装与混凝土层的喷射。本申请具有加强锚杆与边坡锚固力的效果。
