Urban and rural river channel revetment system and laying method

Abstract

The invention relates to an urban and rural river channel revetment system. The urban and rural river channel revetment system is characterized by comprising a revetment body which is laid along the slope surface of a river channel as well as a retaining body which is positioned at the top of the revetment body and laid along the edge of the river channel, wherein the revetment body is formed by laying revetment panels; the retaining body is formed by laying a revetment retaining body and a water collecting tank in a series connection manner; each revetment panel comprises a panel body; and buckling grooves and buckling tenons which can be mutually matched are arranged on the two groups of opposite surfaces of each panel body. The invention further relates to a laying method based on the above urban and rural river channel revetment system. The laying method comprises the following steps: laying of a bedding layer; laying of a base layer; laying of a leveling layer; laying of a geotextile; laying of the retaining body; and laying of the revetment body. By adoption of the above urban and rural river channel revetment system and laying method, sundries can be effectively intercepted from entering the river channel along with rainwater; meanwhile, the construction efficiency is high, the structure is simple, and the later maintenance is convenient; and the above urban and rural river channel revetment system and laying method are applicable to the fields such as urban and rural water-soil preservation, ecological restoration, ecological landscape, river channel revetment engineering, revetment restoration, as well as building or restoration of a revetment zone of a lagging water system or an enclosed water body.

Description

technical field [0001] The invention belongs to the field of urban and rural river management, in particular to an urban and rural river slope protection system and a paving method. Background technique [0002] At present, the new socialist countryside is a strategic decision of our country. Over the past few years, with the continuous advancement of new rural construction, urban and rural areas have taken on a new look, and regional economic development and people's living standards have been greatly improved. my country is rich in water resources, and many areas have lush water systems and numerous rivers. It is an important task for the long-term management of large-scale distribution in urban and rural rivers such as villages and towns to build a new socialist countryside. The long-term management of urban and rural rivers involves many aspects such as flood control and drought relief, environmental protection, water body safety, and the use of water conservancy proje...

Problems solved by technology

[0005] Option 1, geogrid turf slope protection, which has low cost, but is susceptible to human accumulation and biological damage, and has poor erosion resistance; Option 2, stone masonry slope protection, including dry stone slope protection and mortar masonry slope protection, stone masonry slope protection Generally, local materials are used to make full use of local resources. Due to the rough surface of the rocks, the friction between them and the water body is large, which can play a certain role in wave dissipation. This kind of slope protection scheme is not suitable for mechanical operation, and is greatly affected by the local materials and stone sizes. , the thickness of the slope protection is difficult to ensure, and the mortar masonry completely seals the slope surface, which isolates the connection between the slope surface and the water body, and the ecological and landscape effects are poor. This scheme has problems such as difficult construction and long construction period;

[0006] Option 3. Prefabricated concrete interlocking block slope protection, high cost, but good integrity, high strength, less affected by wind, waves and currents, can be mechanized construction, but poor adaptability to embankment slope deformation;

[0007] Option 4: Grass-planting slope protection with sand-free concrete, using a concrete protective frame around it and serving as a mould, filling the middle with sand-free concrete to form, only cement, coarse aggregate and compound fertilizer, and high alkali in the pores of ordinary Portland cement concrete It is difficult to meet the requirements of water conservancy projects for slope protection due to poor ability to adapt to water erosion and uneven foundation settlement.

[0008] In addition, there is generally no sewage pipe network in urban and rural rivers, rainwater is discharged randomly, the construction standard of main drainage canals is low, and the water conservancy conditions are poor, resulting in serious siltation and blockage of rivers and severe river erosion. Going out, forming waterlogging; river cleaning work is affected by many natural conditions, and there are many ways of operation. The common methods are water surface (tour) manual salvage, water surface mechanical cleaning, shore (tour) manual salvage, and interception of floating objects. Various operations Each method has its own characteristics, but it has not fundamentally solved the problem of floating debris pollution in rural rivers; the floating debris in urban and rural rivers comes from straw, leaves, household garbage, plastic bags, etc. mixed with surrounding rainwater when it flows into the river.

None of the existing slope protection schemes can effectively intercept the above-mentioned debris from entering the river with rainwater
