Integrally-cast cement pervious concrete ecological protection slope and construction method thereof

Abstract

The invention relates to an integrally-cast cement pervious concrete ecological protection slope and a construction method thereof. In the invention, a protected slope becomes an integral rigid structure by carrying out in-site casting on a slope required to be protected with macropore pervious cement concrete; an ecological mixing basic layer is slightly spraying on the surface of a pervious cement concrete protecting layer; seeds germinate, grow and can penetrate through a pervious cement concrete protection slope structural layer; and long root-system plants are selected and used to ensure that a pervious cement concrete protection slope is connected with a clay layer of a slope surface substrate together by root systems of vegetation covers. Compared with the prior art, the ecological slope obtained by construction in the invention has the advantages of stable structure, excellent ventilating performance and permeable performance, simpleness and quickness in construction, strong capabilities of water conservation and soil reinforcement, favorable protection effect of the vegetation covers and the like.

Description

technical field [0001] The invention relates to a slope protection for supporting a slope or a side slope, in particular to an ecological slope protection of integrally poured cement permeable concrete and a construction method thereof. Background technique [0002] Slope protection is widely used in the protection of embankments, waterways, embankments, bridges and surrounding slopes or slopes of buildings. It can not only prevent soil erosion, but also effectively protect the stability and safety of embankments, roads, bridges and buildings. [0003] In order to ensure the safety of the slope and its environment, traditional slope protection requires certain support, reinforcement and protection measures. The common structural types are: gravity retaining wall; buttress retaining wall; cantilever retaining wall; slab rib or lattice bolt retaining wall support; . In these traditional slope engineering, the treatment of slopes mainly emphasizes its strength and efficacy, ...

AI Technical Summary

Problems solved by technology

[0008] Disadvantages: Due to the uneven sowing of grass seeds, grass seeds are easily washed away by rain, and the survival rate of grass planting is low, etc., the satisfactory slope protection effect is often not achieved, resulting in slope diseases such as gullies on the slope surface and topsoil loss. Leading to a large number of slope disease remediation and restoration projects, making this technology less used in recent years

[0014] Disadvantages: ①The water retention capacity of the soil is low, and it is easy to form runoff ditch and erosion;

[0015] ②Constructors tend to cut corners and make fakes, forming superficial phenomena;

[0016] ③ Due to improper selection of varieties and insufficient mixing materials, it is easy to cause soil erosion or gullies in the later stage

[0025] Disadvantages: The slope is required to be stable, the slope surface is slightly scoured, and the place with a steep slope is not suitable for areas that have been flooded for a long time.

[0029] Disadvantages: Due to the difficulty in early maintenance and management, the newly laid turf is vulnerable to various natural disasters, and often fails to achieve satisfactory slope protection effects, resulting in slope disasters such as gullies, topsoil loss, and landslides.

[0032] Disadvantages: ① The mortar rubble or brick skeleton must be constructed after the settlement of the subgrade slope is stable;

[0038] Disadvantages: Most of the current geonet mats are made of thermoplastic resin. After the plastic ages, it is easy to form secondary pollution in the soil.

[0041] Disadvantages: require a gentler slope

[0044] Disadvantages: the cost is higher, higher than that of the masonry rubble skeleton slope protection, and it is mostly used for the protection of fill slopes, and because the grass and grass are separated by concrete frame bricks, the overall effect of soil consolidation is not very good

[0048] Disadvantages: grid exposure, metal corrosion, plastic grid aging, alloy performance and other issues, and parts of the exposed grid are easily damaged, and loose stones in the grid are easy to fall out of the grid, which affects this type of retaining wall important factor in safety

[0051] Disadvantages: Due to the limited space environment, the living conditions of vegetation in the later period are limited, and the overall stability is poor
