Rainwater sponge body constructed from solid waste building materials and construction method thereof

Abstract

The invention discloses a rainwater sponge body constructed from solid waste building materials. The rainwater sponge body comprises a water permeable layer, an anti-seepage layer, the solid waste building materials and a water permeable pipe, a cavity is formed between the water permeable layer and the anti-seepage layer, the water permeable layer is located at the top of the cavity, and the anti-seepage layer is located at the side surface and the bottom of the cavity, the cavity is filled with the solid waste building materials, and a sponge water storage body is formed. The water permeablepipe penetrates through the anti-seepage layer outwards from the bottom of the cavity. By means of the rainwater sponge body, recycling of the waste building materials is achieved on the premise thatbasic functions of a sponge system are met, the problems of treatment and functional utilization of waste building materials are solved, and unpowered self-flow irrigation for urban green spaces is achieved. The requirement of urban sustainable development is met, and the construction cost of sponge facilities is reduced. The invention further discloses a construction method of the rainwater sponge body. The method is easy and convenient to implement, and does not influence the greening effect while realizing the sponge effect.

Description

technical field [0001] The invention relates to a rainwater sponge, in particular to a rainwater sponge constructed by using solid waste building materials and a construction method thereof. Background technique [0002] In view of serious urban waterlogging and urban water shortage, the Chinese government advocates the construction of sponge cities, giving full play to the "sponge" role of urban green spaces, natural accumulation, natural infiltration, and natural purification of river and lake water systems. Therefore, the construction of sponge city has become a hot issue in my country's current urbanization construction. At present, most of the sponge water storage facilities in the construction of urban sponge cities in my country adopt the form of PP water storage modules. This material has the advantages of modular assembly and high water collection rate, but it also has problems such as high cost and material degradation. [0003] At the same time, more than 500 mil...

Problems solved by technology

On the one hand, a large amount of construction solid waste is landfilled or piled up, occupying valuable urban space and requiring a lot of manpower and material resources to deal with; on the other hand, construction waste in my country is mainly demolished and abandoned building concrete (such as beams, Columns, floor slabs, wall panels, foundation floors, etc.) and some bricks and tiles, these materials can be recycled as resources, but the current recycling rate of construction waste in my country is less than 5%

[0004] How to apply construction waste to the construction of sponge cities can not only solve the problem of landfilling solid waste, but also solve the problem of high cost and easy degradation of existing sponges, which is one of the researchers' research directions
