Problems solved by technology

[0002] At present, landslides have occurred on many high soil slopes on the banks of reservoirs due to long-term side erosion by water flow, which endangers the safety of residents and roads on the slopes. Slope improvement is required. Most of the existing slope improvement constructions are shotcrete hanging net construction. , this type of slope improvement construction is single, and requires a larger and flatter site for construction. The site available on the mountain is limited, which cannot meet the slope improvement construction on the mountain, and is not suitable for larger and flatter slopes. In addition, gabion grids are commonly used in the existing process of river slope improvement. However, in the face of reservoir bank soil quality, there are many unstable factors, and only through gabion grids for slope improvement, once the grid Binance's own stability cannot meet the requirements, and the entire governance project will fail

Embodiment Construction

[0052] Such as Figure 1 to Figure 10 A comprehensive improvement construction method for an unstable slope is shown, comprising the following steps:

[0053] Step 1. Construction of the slope protection structure, the process is as follows:

[0054] Step 101: Drill multiple sets of first installation hole assemblies on the slope surface of the slope to be regulated 1, and multiple sets of the first installation hole assemblies are arranged along the extension direction of the slope 1 to be regulated; The anchor rod 2 and the anchor cable 3 are installed in the first installation hole assembly, and the anchor rod 2 and the anchor cable 3 are arranged at intervals; wherein, the bottom ends of the anchor rod 2 and the anchor cable 3 are inserted into the slope Inside, the top of the anchor rod 2 and the top of the anchor cable 3 both extend to the top of the slope 1 to be treated, and the length extending out of the slope 1 to be treated is not less than 90 cm; when the anchor ...

Abstract

The invention discloses a comprehensive renovation construction method for an unstable slope. The method comprises the steps that firstly, a slope surface protection structure is constructed; 2, constructing a side slope retaining wall; 3, constructing a slope reinforcing structure; and 4, top drainage ditch construction. The slope surface protection structure and the slope surface reinforcing structure are combined on the slope surface of the to-be-treated slope, the drainage ditch is formed in the slope top, meanwhile, the slope retaining wall is constructed at the slope toe, multiple measures are adopted for treating the to-be-treated slope, multiple protection and reinforcement on the to-be-treated slope are achieved, and the stability of the to-be-treated slope is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of slope construction, and in particular relates to a construction method for comprehensive regulation of unstable slopes. Background technique [0002] At present, landslides have occurred on many high soil slopes on the banks of reservoirs due to long-term side erosion by water flow, which endangers the safety of residents and roads on the slopes. Slope improvement is required. Most of the existing slope improvement constructions are shotcrete hanging net construction. , this type of slope improvement construction is single, and requires a larger and flatter site for construction. The site available on the mountain is limited, which cannot meet the slope improvement construction on the mountain, and is not suitable for larger and flatter slopes. In addition, gabion grids are commonly used in the existing process of river slope improvement. However, in the face of reservoir bank soil quality, there are many...
