Construction method of cast-in-place ecological concrete slope protection

Abstract

The invention relates to a construction method of a cast-in-situ planting type ecological concrete slope protection, which mainly comprises the steps of construction preparation, cast-in-situ construction of a concrete bottom protection, construction of a rubble concrete retaining wall, cast-in-situ construction of a grid, mounting of an erosion-resistant biological blanket, construction of a waterborne platform, construction of a permeable concrete slope protection wall, assembling of frame beams, pouring of planting concrete into the frame beams, mounting of coiled planting material and pouring of a concrete top protection. According to the invention, a slope protection structure is constructed quickly, and the surface of the slope protection is completely ecological from top to bottom.

Description

technical field [0001] The invention relates to a construction method of a cast-in-place planting type ecological concrete slope protection structure. It belongs to the field of foundation and foundation engineering, and is suitable for slope protection projects near water with high greening requirements and amphibious ecology. Background technique [0002] River channel revetment works are engineering measures taken to protect river embankments from water flow, wind and wave invasion and erosion. Usually, the revetment structure of the river mainly includes reinforced soil revetment structure, mortar or dry block stone revetment structure, cast-in-situ concrete gravity retaining wall revetment structure and prefabricated concrete block revetment structure, etc. These revetment structures meet the functional requirements of slope revetment At the same time, it isolates the material exchange between the soil and the water body, destroys the original ecosystem of the river an...

AI Technical Summary

Problems solved by technology

Vegetative ecological concrete slope protection has the characteristics of high strength, large porosity, stable structure, good freeze-thaw resistance, effective suppression of soil loss, and can adapt to various planting methods. The green coverage rate reaches more than 95%, which improves the ecological environment. The environment and landscape can realize long-term sustainable ecological slope protection. However, conventional greening methods such as seed spreading method and turf laying method, which are matched with vegetation-type ecological concrete slope protection, usually have erosion resistance (rainfall, water level changes, water flow erosion, etc.) ) weak ability, poor fertilizer and water retention at the nutrient base, low drought and frost resistance of plants, high post-maintenance costs, and the planting effect is greatly affected by climate factors, etc.
