Construction method of cast-in-site planting concrete revetment

Abstract

The invention relates to the technical field of revetments and provides a construction method of a cast-in-site planting concrete revetment. The concrete revetment manufactured by utilizing the method has the advantages of high strength, good overall landscape effect, strong gradient adaptability, no water-body pollution, water erosion resistance, larger revetment self-weight, safety and reliability, and a water body can be effectively protected. The construction method comprises the following steps of 1, prefabricating acid nutrient soil; 2, arranging a side slope and pouring a concrete lattice frame; 3, pre-placing a nutrient layer; 4, laying inverted-filtering geotechnical cloth on the nutrient layer; 5, pouring planting concrete; 6 carrying out water-preserving, heat-preserving, fertilizer-preserving and alkalinity-reducing processing on the planting concrete; and 7, finally, uniformly spreading the seeds of greening grass and the nutrient soil onto the surface of the planting concrete to form a planting layer with the thickness of 1.8 to 2.2cm, and covering a non-woven fabric onto the surface of the planting layer for watering, moisture preservation and maintenance until the greening grass covers the whole green area.

Description

technical field [0001] The present invention relates to the technical field of slope protection, in particular to a construction method of cast-in-place greening concrete slope protection, which is used for greening and protection of ordinary rivers, roads, and slope projects, combined with anchor rod frame beams, and used for original rigid retaining walls Reconstruction of type embankment, greening of steep rocks. Background technique [0002] With the rapid development of my country's economy, during the construction of highways, railways, water conservancy, mines and other projects, there are often a large number of excavation and filling, forming a large number of exposed slopes, which destroy the ecological balance of nature and bring A series of environmental problems have come, such as soil erosion, landslides, mudslides, local microclimate changes, and destruction of the biological chain. Therefore, it is very necessary to take engineering measures for protection an...

Problems solved by technology

[0003] The known construction methods in the prior art mainly include reserving holes on the concrete slope protection for planting turf. Because the holes in the concrete slope protection are too large and difficult to form, the concrete blocks used for slope protection have relatively low flexural strength. Low, the product is prone to serious damage, after construction, the overall landscape effect is not good, and the slope cannot be covered

In addition, the shape of this kind of product is too large, which is not conducive to manufacturing, transportation, and installation; the shape of this kind of block is small, and its own weight is insufficient, and it is not resistant to water erosion during the flood season, especially when there are plants growing on the concrete block. The flow rate is fast, and the plants and blocks are easy to be pulled out when the flood is soaked, which will damage the stability of the slope

Other types of concrete use inorganic acidic materials to reduce alkali too much, which seriously damages the strength of concrete in the later stage and easily causes water pollution
