Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The utility model provides a town road permeable pavement structure, as shown in figure 1, includes by lower supreme filling layer 1 that sets gradually in the road bed top, screed-coat 2, water guide layer 3, pavement layer 4.

As shown in figure 1, the filling layer 1 is a gravel layer laid above the roadbed, fine sand is mixed between the gravels due to the fact that the gravels are provided with a mixture of sand grains and broken stones, and gaps between the gravels can be filled with the fine sand after the gravels are compacted, so that the supporting stability of the filling layer 1 is improved, and due to the fact that fine gaps exist between the fine sand, rainwater can infiltrate conveniently, and rainwater infiltration efficiency is guaranteed.

As shown in fig. 1, screed-coat 2 is the mixture of coarse sand and fine sand, because the particle diameter of filling layer 1 is great, and its upper surface is uneven, through setting up screed-coat 2, screed-coat 2's upper surface is comparatively level and smooth, can make more level and smooth that road surface layer 4 laid, adopts the mixture of coarse sand and fine sand to further increase screed-coat 2's water permeability moreover. And moreover, fine sand is arranged in the filling layer 1 in an impurity-carrying manner, so that gaps among the gravels are filled, and coarse sand and fine sand of the leveling layer 2 are not easy to flow into the filling layer 1 in the liquid flow.

As shown in fig. 1, the pavement layer 4 is made of pottery clay paving bricks or cement bricks with water permeable holes 531, and the pottery clay paving bricks have many pores and have good water permeability, so that the accumulated water on the ground can quickly enter the ground through the pores after rain, and the ground can not accumulate water in a large area.

As shown in fig. 2, the water guiding layer 3 is formed by splicing a plurality of water guiding modules 5. The water guide module 5 comprises a box body 51 in the positive direction and a water permeable cover 52 covering the box body 51. When the staff fixes the water guide module 5, the box body 51 is horizontally placed on the leveling layer 2, the water permeable cover 52 is covered on the box body 51, and then the laying of the water guide layer 3 is formed through the arrangement of the adjacent box bodies 51. The subsequent staff carries out the laying of the pavement layer 4 on the water permeable cover 52.

As shown in fig. 3, a cylindrical water trap 53 is protruded downward from a middle region of a bottom surface of the case body 51, and the water trap 53 and the inside of the case body 51 communicate with each other. The bottom surface of the water storing box 53 is evenly provided with a plurality of water permeable holes 531 with the diameter of 0.2 cm. When rainwater on the road surface seeps downwards through the road surface layer 4 and enters the box body 51 through the water permeable cover 52, the rainwater on the road surface is transferred and stored, the accumulation of rainwater on the road surface is reduced, the rainwater finally flows into the water storage box 53 and slowly flows into the leveling layer 2 through the water permeable hole 531, the rainwater can slowly seep downwards, and the pressure for discharging the rainwater is reduced.

As shown in fig. 3 and 4, in order to increase the stability of the water guide module 5 in supporting the pavement layer 4, an auxiliary support tower 54 is further disposed on the inner bottom surface of the box body 51, the auxiliary support tower 54 is in a truncated cone shape with a trapezoidal cross section, the upper bottom surface of the auxiliary support tower 54 is parallel to the inner bottom surface of the box body 51, and the lower end of the auxiliary support tower 54 is open and fixed to the edge of the port of the water storage box 53. When making the brick lid that permeates water to house at box body 51 port, the last bottom surface of auxiliary stay tower 54 leans on each other with the lid 52 that permeates water to the lid 52 that permeates water has played the effect of auxiliary stay, makes the lid 52 that permeates water difficult production deformation under the pressure effect, has ensured the stability that water guide module 5 supported. And because the box body 51 is square, the auxiliary supporting tower 54 is positioned right above the middle part, so that the stress of all areas of the water-permeable cover 52 is more balanced.

As shown in fig. 3 and 4, an annular water guide plate 55 is further disposed on the bottom surface of the box body 51, one edge of the water guide plate 55 is fixed to the lower edge of the auxiliary support tower 54, and the other edge of the water guide plate 55 is fixed to the inner wall of the box body 51, so that the lowest point of the water guide plate 55 is located at the connection position with the ground of the box body 51. And a water storage chamber 56 is formed between the water guide plate 55 and the bottom surface of the box body 51. After rainwater enters the box body 51, the rainwater is collected to the water through hole 541 under the flow guidance of the auxiliary support tower 54 and the water guide plate 55, and when the rainwater is small, the rainwater can be immediately collected to the water storage box 53 from the water through hole 541. When the rainwater is large, the liquid level in the box body 51 gradually increases, and when the liquid level reaches the outer edge of the water guide plate 55, the water guide plate 55 is located at the connection part with the inner wall of the box body 51, and a plurality of water through holes 551 are formed in the direction of the water storage cavity 56. The rainwater can guide too much rainwater into the water storage cavity 56 through the water passing holes 551, so that the possibility that the rainwater is accumulated too much in the box body 51 and the rainwater is seeped back is reduced. And a plurality of drain holes 561 are evenly arranged on the bottom surface of the water storage cavity 56, so that rainwater can be timely drained from the water storage cavity 56, and the drain areas of the drain holes 561 do not conflict with the drain areas of the water storage box 53, so that rainwater can be evenly distributed, and rainwater infiltration efficiency is improved.

As shown in fig. 1 and 5, a cylindrical water flowing channel 57 is provided in the bottom of the water storing box 53 in the filling layer 1, so that rainwater can flow into the water flowing channel 57 and seep underground through the inner wall of the water flowing channel 57 after being discharged through the water storing box 53.
