Embodiment 1
[0029] Step 1: On-site investigation: Investigate the dam foundation of the barrier lake stone dam, determine the thickness of the concrete hexagonal prefabricated block, the ratio of the height of the dam to the height of the concrete hexagonal prefabricated block is 15m to 5m, and detect the depth of the dam foundation to see if it meets the requirement of at least 3m bottom Mud, and determine whether there are culverts;
[0030] Step 2: Thicken the slope foot: use the soil layer to cover the slope foot, the thickening thickness is 20cm, and use turf slope protection on the top of the thickened surface;
[0031] Step 3: Substrate improvement: Mix the concrete with an environment-friendly bottom modifier to get the filling material, insert the guide pipe into the slope toe, and use the filling device to build the filling material, so that the bottom of the slope toe will form a hard base, and Cooperate with surface covering soil;
[0032] Step 4: Culvert treatment: Determine...
Embodiment 2
[0038] Step 1: On-site investigation: Investigate the dam foundation of the barrier lake stone dam, determine the thickness of the concrete hexagonal prefabricated block, the ratio of the height of the dam to the height of the concrete hexagonal prefabricated block is 20m to 10m, and detect whether the bottom depth of the dam foundation is at least 5m Mud, and determine whether there are culverts;
[0039] Step 2: Thicken the slope foot: use the soil layer to cover the slope foot, the thickening thickness is 30cm, and use turf slope protection on the top of the thickened surface;
[0040] Step 3: Substrate improvement: Mix the concrete with an environment-friendly bottom modifier to get the filling material, insert the guide pipe into the slope toe, and use the filling device to build the filling material, so that the bottom of the slope toe will form a hard base, and Cooperate with surface covering soil;
[0041] Step 4: Culvert treatment: Determine the size of the culvert. ...
