Description
Technical Field
The utility model belongs to the technical field of the sponge city, concretely relates to sponge city road surface of permeating water.
Background
Along with the process of Chinese urbanization is accelerated, not only the heavy rain often causes serious urban waterlogging, but also the rainwater can not well get into the urban underground water circulation system when a small amount of rainfall, and when meeting rainy days, the road surface can produce ponding, which seriously affects the trip of pedestrians. The reasons for the above phenomena are mainly that the urban road area is too large, and the water absorbing and draining capacity of the urban road system is poor. At present, the solutions for the problems in China mainly include the steps of increasing the diameter of a drainage pipe, storing water on line, building a reservoir and the like, and the measures not only generally have the defects of large investment, large occupied space and the like, but also have long construction time and low efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough of prior art, provide a sponge city permeable pavement, concrete scheme is as follows:
a sponge urban permeable pavement comprises a pavement body and drainage ditches arranged on two sides of the pavement body; the pavement body sequentially comprises a permeable brick layer, a gravel layer, a permeable concrete layer, a water storage layer and a tamping roadbed from top to bottom, wherein an aggregate layer is pressed on the surface of the tamping roadbed, a supporting plate for supporting the permeable concrete layer is arranged on the aggregate layer, the extending direction of the supporting plate is consistent with the extending direction of a road, and a notch is formed in the bottom of the supporting plate; the water permeable brick layer is formed by splicing water permeable bricks which are matched with each other, a vertically crossed through type drainage channel is arranged inside each water permeable brick, the front, the rear, the left and the right of each water permeable brick are respectively provided with an end socket or a sinking groove corresponding to the end socket, and the upper surface of each water permeable brick is provided with a water leakage hole extending to the drainage channel; the top of the drainage ditch is covered with a grate plate, and the side surface of the drainage ditch is provided with a through hole communicated with the drainage channel.
Based on the above, the surface equipartition of brick that permeates water is equipped with dentate anti-skidding line, the hole that leaks is located between the anti-skidding line.
Based on the above, the pervious concrete layer is formed by splicing prefabricated plates.
Based on the above, the compacted roadbed and the aggregate layer on the surface of the compacted roadbed have the tendency of high middle and low two sides.
The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:
1. the utility model discloses in, the structural design of road surface body makes the rainwater can permeate or arrange the escape canal to the underground fast, effectively avoids the emergence of surface gathered water phenomenon.
2. The utility model discloses in, the structural design of water-storage layer plays certain buffering effect to under the super heavy rainstorm condition, the in-process of secret infiltration.
3. The utility model discloses in, the escape canal design of road surface body both sides makes near the water in escape canal discharge fast, leads to the road intermediate position infiltration volume relatively great, so will tamp road bed and surperficial aggregate layer design for be middle high, the low trend in both sides for the water of infiltration water-storage layer flows to both sides, plays a balancing act, also accelerates the infiltration speed simultaneously.

In the figure: 1. a permeable brick layer; 1-1, water permeable bricks; 1-2, end head; 1-3, sinking a groove; 1-4, water leakage holes; 1-5, anti-skid lines; 1-6, a drainage channel; 2. a crushed stone layer; 3. a pervious concrete layer; 4. a aquifer; 5. a bone material layer; 6. tamping the roadbed; 7. a support plate; 8. a notch; 9. a drainage ditch; 10. a grid plate; 11. and a through hole.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Examples
As shown in figures 1-3, the utility model provides a sponge city permeable pavement, including road surface body and setting the escape canal 9 of road surface body both sides.
The road surface body is from last down be permeable to water brick layer 1, metalling 2, permeable concrete layer 3, water-storage layer 4 and tamp road bed 6 in proper order, tamp road bed 6 surface pressure is equipped with aggregate layer 5, be equipped with the support on aggregate layer 5 permeate water concrete layer 3's backup pad 7, the extending direction of backup pad 7 is unanimous with the road extending direction, and breach 8 is seted up to the bottom of backup pad 7.
The water permeable brick layer 1 is formed by splicing water permeable bricks 1-1 which are matched with each other, a penetrating type drainage channel 1-6 which is vertically intersected is arranged inside the water permeable brick 1-1, the front, the back, the left and the right of the water permeable brick 1-1 are respectively provided with an end 1-2 or a sink 1-3 which corresponds to the end 1-2, and the upper surface of the water permeable brick 1-1 is provided with a water leakage hole 1-4 which extends to the drainage channel 1-6.
The top of the drainage ditch 9 is covered with a grid plate 10 for filtering impurities, and the side surface of the drainage ditch 9 is provided with a through hole 11 communicated with the drainage channels 1-6.
It should be noted that tooth-shaped anti-slip lines 1-5 are uniformly distributed on the surface of the water permeable brick 1-1, and the water leakage holes 1-4 are positioned among the anti-slip lines 1-5, so that the water permeable brick not only can play a role of anti-slip, but also can play a role of protecting the water leakage holes 1-4 to a certain extent.
It should be noted that, in order to facilitate the laying of the pervious concrete layer 3, the pervious concrete layer 3 is formed by splicing prefabricated plates.
Considering that the design of the drainage ditch 9 on both sides of the pavement body enables water near the drainage ditch 9 to be rapidly discharged, and the water seepage amount at the middle position of the road is relatively large, so that the compacted roadbed 6 and the aggregate layer 5 on the surface of the compacted roadbed are designed to have the trend of high in the middle and low on both sides, so that the water permeating into the water storage layer 4 flows to both sides, a balance effect is achieved, and the water seepage speed is accelerated.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
