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. ...

Abstract

The invention discloses a danger-removing, reinforcing and seepage-preventing method for a stone dam of a barrier lake in the technical field of environmental restoration. The method comprises the following steps of 1, site exploration, 2, slope toe thickening, 3, substrate improvement, 4, culvert treatment, 5, landslide reinforcing, 6, anti-seismic reinforcing and 7, danger removing and seepage preventing. According to the danger-removing, reinforcing and seepage preventing method for the stone dam of the barrier lake, environment restoration scheme design is carried out in a targeted mode, danger-removing, reinforcing and seepage preventing treatment is carried out on the stone dam of the barrier lake in multiple directions, a stone dam system of the barrier lake can be efficiently recovered, the stability of the stone dam of the barrier lake is recovered, long-term health and stability of the stone dam of the barrier lake are achieved, the operation is easy, the effect is quick, the environment is not damaged, the environment-friendly function and the ecological function are both achieved, and the safety and the service life are effectively guaranteed.

Description

technical field [0001] The invention discloses a method for eliminating danger, reinforcing and anti-seepage of stone dams of dammed lakes, and specifically belongs to the technical field of environmental restoration. Background technique [0002] Barrier lakes are lakes formed by volcanic lava flows, moraines, or mountain rocks collapsed by seismic activity, etc., which block valleys, river valleys or riverbeds and store water behind them. There are four types of barrier lakes. The first is the original water system; the second is that the original water system is blocked by blockages; the third is that after the valley and the river bed are blocked, the flowing water gathers and overflows around; the fourth is that the water storage reaches a certain level to form a barrier lake. Once the Saihu Lake bursts, it will form a flood peak downstream, and improper handling will cause major disasters. [0003] In the cooperative protection of the barrier lake, it is necessary to ...
