Problems solved by technology

However, the above ecological materials generally have problems of poor durability and replantability, and the time for rainfall runoff to flow through the slope is short, and pollutants cannot be effectively removed. When the rainfall runoff flow is large, the interception and purification effect is more limited.

Embodiment Construction

[0016] Control attached figure 1 , the ecological restoration method of the concrete revetment slope, a rectangular sand-free concrete sump 4 is arranged on the side of the road at the junction of the road and the bank slope, and a gravel cushion 5 with a diameter of Φ20-50 is laid on the bottom of the groove. Permeable sand-free concrete drainage ditches 2 perpendicular to the sump 4 are arranged at regular intervals on the slope of the concrete revetment 1, and both sides of the drainage ditch 2 are formed of permeable sand-free concrete ridges 9. An impermeable sand-free concrete overflow ridge 6 is set between the rectangular sand-free concrete sump 4 and the permeable sand-free drainage ditch 2, and the sump 4 and the drainage ditch 2 are filled with Φ100-200 gravel. During construction, roughen the slope of the concrete revetment 1, and build a small groove; arrange a geocell 11 on the roughened slope, and lay an 80mm thick slope cell sand and gravel cushion 12 in the ge...

Abstract

The invention discloses a hard reinforced concrete revetment slope biological repairing method, which is characterized by comprising the steps of: roughing a concrete revetment and constructing drainage ditches at set intervals; digging a water collecting tank on one side of the cross of the revetment and a road, reserving an opening at the joint of the drainage ditch and the water collecting tank, and constructing a watertight concrete overflow bank; filling gravels in the water collecting tank and the drainage ditches; and welding earthwork grids by high-density polyethylene stripes on the protection slope, laying gravel cushion coats in the earthwork grids, and finally pouring biological slurry. The method has the advantages that: the whole project is stable and safe; rain flows into the water collecting tank and passes through grave areas, non-watertight sand-free concrete, a slope cushion coat, plant roots and the like to seep into rivers, so water quality is improved to a relatively large extent; when rainfall runoff is overlarge, the rain overflows from the overflow bank and passes through the graves of the drainage ditches, so the water quality is also purified to a certain extent, meanwhile the slope is protected; the biological slurry poured onto the slope is prepared from biological materials, and has certain anti-erosion strength and can be used as a substrate for plant growth, so the cost is low and the operation is simple.

Description

technical field [0001] The invention relates to an ecological restoration method for concrete revetment slopes, belonging to the fields of river ecological revetment and river water quality purification. Background technique [0002] In traditional river improvement projects, rigid materials such as mortar or dry block stones, cast-in-place or prefabricated concrete are often used for slope protection. This type of slope protection can well protect the river slope and realize the flood discharge, drainage and water and soil protection of the river. It has the advantages of good stability, land saving, and high degree of construction mechanization. However, with the development of social economy, people's ecological concept is getting stronger and stronger, and they gradually realize that this type of slope protection will have a negative impact on the ecosystem, and the hard slope accelerates the runoff of rainwater and the direct flow of pollutants into the river. . In or...
