Embodiment 1
[0023] The preparation method of the self-cleaning permeable concrete structure in Example 1 comprises the following steps: first laying a permeable concrete bearing layer 3, placing a permeable geotextile after rolling for the first time, laying a surface protection layer, and rolling for the second time . Because the particle size of the first aggregate in the permeable concrete surface protection layer 1 is smaller than the particle size of the second aggregate in the permeable concrete bearing layer 3, the particles in the permeable concrete surface protection layer 1 are likely to affect the Pores in the permeable concrete bearing layer 3 cause pollution, and such a construction procedure and the use of permeable geotextiles can effectively avoid this problem.

The invention discloses a self-cleaning permeable concrete structure and a preparation method thereof. The concrete structure comprises a surface protection layer, a permeable geotextile layer and a permeable concrete bearing layer, and a water storage device for storing rainwater and groundwater is arranged in the permeable concrete bearing layer , a cleaning device for cleaning blockages using water from the water storage device, a detection device for detecting the permeability of the self-cleaning permeable concrete structure, and a control system connected to the water storage device, the cleaning device and the detection device respectively. In the method, a permeable concrete bearing layer is laid at first, a permeable geotextile is placed after the first rolling, and then the surface protection layer is laid, and the second rolling is performed. The invention not only can regularly detect the permeability of the permeable concrete, but also can realize the self-cleaning of the pores in the permeable concrete, avoid blockages from staying in the pores of the permeable concrete, prevent the clogging of the permeable concrete and ensure smooth drainage.
Description
technical field [0001] The invention relates to a permeable concrete structure and a preparation method thereof, in particular to a self-cleaning permeable concrete structure and a preparation method thereof. Background technique [0002] The wide application of permeable concrete can convert part of the surface runoff into underground runoff, effectively reducing the burden on the urban drainage system, which is of great significance to the safety of the city. The reason why pervious concrete is more permeable than ordinary concrete is that there are a large number of pores inside it, and the decrease in permeability caused by pore blockage is the main problem faced by pervious concrete. [0003] At present, the solution to this problem mainly focuses on solving the problem from the aspects of permeable concrete structure and raw material mix ratio. The existing permeable concrete structure cannot realize self-cleaning and intelligent control. Contents of the invention ...
