technical field

The utility model relates to the technical field of permeable concrete, in particular to an anti-blocking structure of permeable concrete.

Background technique

In recent years, with the development of the national economy, my country's urbanization process has been significantly improved, and the rapid development of urbanization has led to an increase in the distribution ratio of impermeable surfaces on the ground. Common surface materials in cities are mostly hardened pavement materials such as concrete, granite, and ceramic tiles. However, their impermeability and airtightness have caused a series of changes in the urban ecological environment. One of the most serious problems is the rainfall produced by urban pavements. As the flow rate increases, the flood coefficient is obviously too large, and the surface flood generated by rainfall cannot penetrate into the ground, causing waterlogging disasters in urban areas. At the same time, because natural precipitation cannot penetrate into the ground smoothly, it destroys the natural water cycle, wastes the increasingly tense natural fresh water resources, affects the growth of surface plants, and also causes the "heat island effect" of urban ecological deterioration. Permeable concrete is an environmentally friendly high-permeability material. It has good water permeability and air permeability, which can solve the above problems. At the same time, it also has the function of sound absorption and noise reduction, which is of great significance to the urban surface. The reason why permeable concrete is permeable is due to its high porosity. It can be said that porosity is the most critical factor in determining the water permeability of permeable concrete.

However, when the water flows through the pervious concrete, mineral or organic fine particles will continue to enter the pores with the water flow, and the pores will be blocked, resulting in a continuous decrease in the permeability of the pavement, making it difficult to perform the function of the permeable pavement, making it evolve into a non-permeable pavement , causing economic waste.

Utility model content

The purpose of this utility model is to solve the problem that in the prior art, when the water flows through the permeable concrete, mineral or organic fine particles will continuously enter the pores with the water flow, and the pores will be blocked, which will lead to the continuous decrease in the permeability of the road surface. A pervious concrete anti-blocking structure.

In order to achieve the above object, the utility model adopts the following technical solutions:

An anti-blocking structure of permeable concrete, comprising a base, the top of the base is provided with a bearing layer, the side of the bearing layer away from the base is provided with a filter layer, and the side of the filter layer away from the bearing layer is provided with The barrier layer is provided with a plurality of water holes, and the side of the barrier layer away from the filter layer is provided with a water gap layer.

Preferably, the base layer is a permeable concrete layer.

Preferably, the bearing layer is a gravel layer.

Preferably, the barrier layer is a waterproof geotextile layer.

Preferably, the water hole is in the shape of a cone.

Preferably, the water gap layer is a sand-free permeable concrete floor brick layer.

Beneficial effect:

The setting of the bearing layer can improve the bearing capacity of the road surface, and the setting of the filter layer can facilitate the passage of water, and can filter mineral or organic fine particles at the same time. The utility model can effectively improve the water permeability of the permeable concrete pavement through the setting of the filter screen structure and the water holes, thereby effectively avoiding pore blockage caused by mineral or organic fine particles.
