The technical field is as follows:

the utility model relates to a road flat stone brick and the water conservancy diversion way of permeating water especially relates to a bituminous paving water conservancy diversion road flat stone and water conservancy diversion way structure of permeating water.

Background art:

along with the continuous acceleration of the nationwide urbanization process and the continuous expansion of urban construction, the road hardening needs are continuously increased, the urban population is continuously expanded, urban waterlogging frequently occurs after the road traffic pressure is sharply increased, the phenomenon of 'seeing the sea' in cities is caused, great inconvenience is brought to the work and life of people, and some potential safety hazards are generated. From this the construction in sponge city is advocated vigorously in the country, solves the drainage problem of urban rainwater. The road flat stone is a common building material on an asphalt pavement, the common materials are granite materials and cement prefabricated plates which are all waterproof materials, and rainwater flows into a catch basin grate plate along the surface of the road flat stone when heavy rain comes; when the rainfall is too large, rainwater can cause driving danger on the road surface because the rainwater is not drained in time, and meanwhile, a large amount of pavement garbage is flushed into a rainwater well by rainwater to easily cause the deposition and blockage of a drainage system pipe. The appearance of the products of the present situation is not changed when the products of the road surface materials, particularly the road flat stones, are used.

In order to solve the problem of road water accumulation, a large number of single water permeable bricks and preparation methods thereof appear, for example, Chinese patent publication No. CN105924057A entitled "A Water permeable brick and preparation method thereof", which is prepared from specific cement, stone, gelatinizing agent coloring dispersant and water. And the CN106630825A composite permeable brick comprises a surface layer and a bottom layer, wherein the surface layer comprises aggregate, a surface layer binder, a water reducing agent and water, and the bottom layer comprises aggregate sand, cement, dispersible latex powder, a cement alkali inhibitor, a water reducing agent, water and the like. And also CN1067187A cement concrete permeable bricks, permeable pavements and production methods thereof. In the Chinese patent CN103664060A, the aggregate sand stone of the surface layer of the water permeable brick is pre-coated with epoxy resin, and then organic resin is added as a binder to increase the binding property of the material, but the difference exists between the bottom layer and the surface layer by using the method and the raw materials, so that the bottom layer and the surface layer are difficult to bind and mix to form a whole, and meanwhile, the preparation process is long, so that the production cost of the product is increased, and the popularization and the application are difficult.

The size of the manufactured permeable diversion flat stone can be changed according to the specific requirements of road traffic design, the thickness of the permeable diversion flat stone is generally not less than 60MM, the bottom layer is diabase and the like or other broken stones, the permeable concrete porous structure is adopted, the surface layer is of a cement-based or polymer silica sand micro-porous structure, the large-sized block brick machine is formed by high-pressure and high-frequency vibration pressing, the surface layer is fine in pores, wear-resistant and attractive, large-particle objects can be prevented from entering the bottom layer, the porosity of the surface layer and the bottom layer can reach more than 20%, the water permeability can reach more than 0.2MM/s, the permeable diversion flat stone can be adjusted according to needs, the compressive strength can reach 45 MPa, the bending resistance is 4.0 MPa, the urban vehicle-mounted load is completely met, meanwhile, different colors can be given to the surface layer to serve. Under the extreme condition in the use, when the road plat stone surface is blockked up because the road excessively pollutes to design concave structure and can in time discharge road ponding, do not influence the getting rid of road surface water, only need the high pressure squirt to wash the surface after the fact and can resume most function of permeating water.
