Description

Technical Field

[0001] The utility model belongs to the technical field of spoil dump slope protection, in particular to a spoil dump slope waterproofing structure. Background Art

[0002] A spoil dump, also known as a waste rock dump, refers to a place where mining waste is concentratedly discharged. Mining refers to open-pit mining and underground mining, including open-pit stripping and shaft excavation and development during mine infrastructure construction. The waste generally includes humus topsoil, weathered rock and soil, hard rock and mixed rock and soil, and sometimes also includes potentially recoverable off-surface ores and lean ores.

[0003] During the greening and land restoration process of the spoil dump, the bottom layer of the spoil dump needs to be protected by stone masonry to prevent rainwater erosion and river water in the rainy season from endangering the safety of the spoil dump. However, the use of stone masonry without green embellishment is not beautiful enough, and a single slope protection plant is easily affected by rainwater erosion, and the plants are not easy to survive. For this reason, it is necessary to provide an external spoil dump slope waterproofing structure, and adopt the method of planting slope protection plants in the masonry bricks to stabilize the spoil dump, prevent soil and water loss and beautify the environment at the same time.

[0021] Hereinafter, an embodiment of the external dump slope waterproofing structure of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4 The utility model shows an external spoil dump slope waterproof soil loss structure of an embodiment of the utility model, including a supporting square column 2 laid at the bottom of the slope surface of the spoil dump slope protection 1, and both sides of the top of the supporting square column 2 are engaged with a positioning sleeve 12, and the top of the positioning sleeve 12 is penetrated by two limit pins 13, and the limit pin 13 penetrates the positioning sleeve 12 and is implanted in the spoil dump slope protection 1. Through the coordinated use of the positioning sleeve 12 and the limit pin 13, the supporting square column 2 is pressed and fixed, so that the supporting square column 2 can be stably formed into a triangular brick 3 provides support to ensure the stability of the triangular bricks 3 and the hexagonal hollow bricks 5 after installation.
