Self-cleaning elastic water guide assembly, ecological permeable pavement and pavement construction method

Abstract

The invention discloses a self-cleaning elastic water guide assembly, an ecological permeable pavement and a pavement construction method, the elastic water guide assembly comprises a mounting plate, a plurality of through holes are formed in the mounting plate, elastic water guide pieces are arranged on the through holes, permeable cavities communicated with the through holes are formed in the elastic water guide pieces, and the permeable cavities are communicated with the upper ends and the lower ends of the elastic water guide pieces; the wall face of the elastic water guide piece is provided with a flow channel communicating the water through cavity with the exterior of the elastic water guide piece, the upper end of the flow channel extends to the upper end of the elastic water guide piece, and the flow channel narrows when the elastic water guide piece is pressed and resets after pressure is eliminated. When the elastic water guide piece is pressed, a flow channel can be shrunk, a pulse airflow from top to bottom is formed in the water permeable cavity to blow impurities such as dust and sand in the water permeable cavity into a soil layer below the mounting plate through the through holes, self-cleaning in the water permeable cavity is achieved, blockage of the impurities in the water permeable cavity is reduced, and the permeable effect and the compressive strength of the permeable pavement are obviously improved.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to an elastic water-guiding component with a self-cleaning function, and an ecological permeable road surface and a road surface construction method using the elastic water-guiding component. Background technique [0002] In recent years, there have been many reports of urban waterlogging disasters. The main reason is that urban roads have poor water permeability, traditional urban drainage cannot timely divert a large amount of precipitation, and the internal drainage system is old and silted. In response to this situation, the concept of sponge city has gradually attracted the attention of the society. Sponge city, as a new generation of urban stormwater management concept, expects the city to have excellent drainage capacity to cope with floods and other disasters. [0003] Ecological permeable pavement is an important part of sponge city. At present, permeable pavements ...

Problems solved by technology

However, such permeable pavement has the following problems: firstly, the permeable pores of the road paved with permeable materials are easily blocked by sand, mud and dust, resulting in a decrease in water permeability, or even completely losing the permeable function; secondly, the use of permeable materials For paving pavement, because the permeable material has pores for water permeation, the carrying capacity of traditional permeable pavement is poor, and the cost is high, not economical, and low cost performance; finally, traditional permeable pavement is difficult to maintain. Once the permeable material loses its permeable function, It is difficult to repair and can only be replaced as a whole after being destroyed, which is costly and cumbersome

[0004] In order to solve the above problems, the patent CN204728165U discloses a kind of ecological permeable pavement, the permeable pavement adopts vertical aqueducts, and the water permeated into the permeable brick layer can enter The upper opening of the aqueduct flows down to the gravel layer or the gravel layer, and the gap between the gravel layer and the gravel layer is used to accommodate a large amount of water to reduce the water on the road. However, dust and debris are easy to accumulate in the aqueduct. Cause the water pipe to block and lose the diversion effect

Patent CN206692979U discloses a permeable pavement. The permeable pavement uses a vertical channel to guide the rainwater accumulated on the road surface to the ground, and at the same time uses a sealing block to block the upper end of the channel. Stretching the sealing block to open the diversion channel is difficult for large-scale application due to its complicated structure and high installation cost. Moreover, using water to trigger the diversion channel will not only cause the local diversion channel to expand and open due to draft, causing dust and debris to enter, but also lead to The dust and debris entering the flow channel cannot be effectively cleaned
