Description
Technical Field
The invention relates to the field of sponge city construction, in particular to a permeable road structure for sponge city construction.
Background
The city is a place with high population concentration and highly developed social economy, and is also a place with the most outstanding contradiction between resources and environmental bearing capacity. In recent years, due to climate change and weakened environment bearing capacity, the urban water ecology faces two extremes: on one hand, urban waterlogging is serious, and rain and flood management becomes a potential safety hazard influencing urban development; on the other hand, most cities have serious water shortage and water resource supply is seriously insufficient. A series of problems such as water ecological deterioration, water resource shortage, water environment pollution, lack of guarantee of water safety and the like are brought. With the development of socio-economy and frequent urban meteorological disasters, the urban requirements on drainage engineering are higher and higher. Therefore, to maintain the continued development of urban health, the urban water ecology must be restored.
In recent years, urban waterlogging caused by a few rainstorms also makes strengthening of utilization of rain and flood and drainage and storage of waterlogging become social concerns. The sponge city can be like a sponge, has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters and the like, absorbs water, stores water, seeps water and purifies water in rainy days, and releases the stored water for utilization when needed. The 'sponge city' aims to build a vertical system of the city, so that the city can breathe freely, store and discharge water, and the water is part of the city.
The most important point for municipal road construction of sponge cities is that water seepage can be realized, and surface runoff is absorbed through water permeable road construction so as to supplement underground water and relieve urban heat island effect.
The water permeable bricks developed and used at present can be roughly divided into five types according to the materials: cement concrete water permeable bricks, ceramic water permeable bricks, natural sand water permeable bricks, slag water permeable bricks and the like. The water permeation principle is the same, although they differ in the raw materials and production processes used. The realization of the water permeable function of the water permeable brick is mainly as follows: water permeates into the underground soil along the open continuous pore channels in the brick body under the action of gravity.
The service life of the water permeable brick as one of the water permeable pavement paving materials depends on the technical indexes of the water permeable brick such as compression resistance, breaking strength, freeze-thaw resistance, wear resistance and the like, more importantly, the time limit of gradual attenuation and final loss of the water permeable performance under the action of environmental factors, namely the timeliness of the water permeable brick for keeping the water permeable performance. For the water permeable brick, clear water is not permeated in many cases, but turbid water containing a certain amount of dust and sand grains with different grain sizes is permeated; the dust in the turbid water can produce the deposit of certain degree in the permeable pores of the permeable brick, and the deposit amount can be gradually increased day by day, finally resulting in the blockage of the permeable pores of the brick body, so that the permeable rate of the brick body is attenuated until the permeable capacity is completely lost.
Therefore, if the water permeability of the permeable road is maintained for a long time, the problem in the construction process of the current sponge city is still solved.
