Ecological type slope protection structure and construction method

Abstract

The invention relates to an ecological type slope protection structure and a construction method. The ecological type slope protection structure mainly comprises a prefabricated assembled type frame lattice beam, a vegetative coiled material, a vegetative concrete slab, a water-permeable ribbed plate pile wall, a water-permeable concrete guard wall and a ecological type hydrophilic platform, wherein the vegetative concrete slab and the vegetative coiled material are sequentially arranged in a space enclosed by a slope surface longitudinal beam and a slope surface transverse beam from bottom up; the ecological type hydrophilic platform is arranged in the middle of a side slope; and the water-permeable ribbed plate pile wall is arranged at the bottom of the side slope. The ecological type slope protection structure, disclosed by the invention, is high in construction speed, and the slope protection surface is fully ecological from top to bottom. The invention further provides the construction method of the ecological type slope protection structure.

Description

technical field [0001] The invention relates to an ecological slope protection structure and a construction method. 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 and lake shore area, causes a decline...

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%, improving 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 that are matched with vegetation-type ecological concrete slope protection usually have the anti-erosion (rainfall, water level change, water flow erosion) of the covering layer. ) weak ability, poor fertilizer and water retention at the nutrient base, low drought and frost resistance of plants, high maintenance costs in the later period, and the planting effect is greatly affected by climate factors, etc.
