Description
Technical field
The utility model relates to municipal drainage field, is specifically related to a kind of road drainage structure with water permeability.
Background technology
On park road, many employings arrange gutter by the road and carry out surface drainage.When running into that the rainy day, amount of precipitation was less, may can't be formed on road surface and large current are flowed in gutter, little puddle will be formed on pavement, affect pedestrian's walking.When running into that the rainy day, amount of precipitation was larger, displacement strengthens, and may form torrent in the cover plate place on gutter, have little time to flow in gutter, can cause pavement water logging.Therefore, just need to consider more draining, permeable problem how designing on the road pavement of pavement.
Utility model content
For there being the defect of technology on overcoming, the purpose of this utility model is intended to propose a kind ofly permeable infiltration also can to carry out the road drainage structure with water permeability of draining.
For achieving the above object, the utility model adopts following technical scheme:
There is a road drainage structure for water permeability, comprise permeable stratum structure and draining earth formation, it is characterized in that: described permeable stratum structure comprises the first plain soil layer, graded sand gravel bed, pervious concrete permeable formation, medium sand leveling layer and water-permeable brick; Described first plain soil layer is positioned at the bottom of permeable stratum, re-lays graded sand gravel bed after the first plain soil layer is covered with one deck geotextiles; Pervious concrete permeable formation is re-layed after described graded sand gravel bed upper berth is provided with one deck geotextiles; Described pervious concrete permeable formation lays medium sand leveling layer; Described medium sand leveling layer is equipped with water-permeable brick, the back-up sand of water-permeable brick brickwork joint; Described draining earth formation is arranged on the side of permeable stratum structure; Described draining earth formation comprises the second plain soil layer, hardcore bed, concrete gutter; Described second plain soil layer is positioned at the bottom on draining stratum; Described second plain soil layer is equipped with hardcore bed; Described hardcore bed is installed concrete gutter; Be provided with the tube connector be connected with catch pit in described concrete gutter, the end face in concrete gutter is provided with the water drainage cover board with water-permeable brick same plane layer; Described water drainage cover board is embedded in water-permeable brick and concrete gutter by stainless steel filler rod.
Explanation and the further scheme of such scheme are as follows:
1. compacted density >=95% of the first plain soil layer and the second plain soil layer described in, Rebound Modulus of Subgrade EO=30MPa.
2. described in, the thickness of graded sand gravel bed is 150-180mm.
3. described in, the porosity of pervious concrete permeable formation is 30-40%.
4. described in, the thickness of medium sand leveling layer is 30-40mm.
5. the thickness of hardcore bed described in is 100-110mm.
6. tube connector described in is UPVC pipe.
Because technique scheme is used, the utility model compared with prior art has following advantages:
A kind of road drainage structure with water permeability that the utility model provides has excellent road drainage performance.Ponding on road surface can infiltrate in each pervious layer by permeable stratum structure, finally flows in soil and converges with underground water.Ground torrent when rainy or when there is waterlogging, can enter in gutter by draining earth formation in time.Two earth formations cooperatively interact, and reduce the Seepage flow time of water, improve drainage performance, decrease the possibility that waterflooding occurs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model most preferred embodiment.
In above accompanying drawing: 1, permeable stratum structure; 2, draining earth formation; 3, the first plain soil layer; 4, graded sand gravel bed; 5, pervious concrete permeable formation; 6, medium sand leveling layer; 7, water-permeable brick; 8, geotextiles; 9, the second plain soil layer; 10, hardcore bed; 11, concrete gutter; 12, tube connector; 13, water drainage cover board; 14, stainless steel filler rod.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment 1: shown in Figure 1:
Have a road drainage structure for water permeability, comprise permeable stratum structure 1 and draining earth formation 2, described permeable stratum structure 1 comprises the first plain soil layer 3, graded sand gravel bed 4, pervious concrete permeable formation 5, medium sand leveling layer 6 and water-permeable brick 7; Described first plain soil layer 3 is positioned at the bottom of permeable stratum, re-lays graded sand gravel bed 4 after the first plain soil layer 3 is covered with one deck geotextiles 8; Pervious concrete permeable formation 5 is re-layed after described graded sand gravel bed 4 is equipped with one deck geotextiles 8; Described pervious concrete permeable formation 5 lays medium sand leveling layer 6; Described medium sand leveling layer 6 is equipped with water-permeable brick 7, the back-up sand of water-permeable brick 7 brickwork joint; Described draining earth formation 2 is in the side of permeable stratum structure 1; Described draining earth formation 2 comprises the second plain soil layer 9, hardcore bed 10, concrete gutter 11; Described second plain soil layer 9 is positioned at the bottom on draining stratum; Described second plain soil layer 9 is equipped with hardcore bed 10; Described hardcore bed 10 installs concrete gutter 11; Be provided with the tube connector 12 be connected with catch pit in described concrete gutter 11, the end face in concrete gutter 11 is provided with the water drainage cover board 13 with water-permeable brick 7 same plane layer; Described water drainage cover board 13 enters in water-permeable brick 7 and concrete gutter 11 by stainless steel filler rod embedding 14; Compacted density >=95% of described first plain soil layer 3 and the second plain soil layer 9, Rebound Modulus of Subgrade EO=30MPa; The thickness of described graded sand gravel bed 4 is 150-180mm; The porosity of described pervious concrete permeable formation 5 is 30-40%; The thickness of described medium sand leveling layer 6 is 30-40mm; The thickness of described hardcore bed 10 is 100-110mm; Described tube connector 12 is UPVC pipe.
When raining or when road surface there is ponding, flow in concrete gutter 11 if water can not form current, namely flow in soil by water-permeable brick 7, each pervious layer, converge with underground water.Along with the transmission coefficient of graded sand gravel bed 4 increases; The Seepage flow time of water leaking-in in road structure shortens, and drainage performance improves; Graded sand gravel bed 4 has good drainage effect, can reduce the generation of Moisture Damage.If because amount of precipitation is large, current are comparatively anxious, then can flow directly in concrete gutter 11, finally flow in catch pit.
Embodiment 2: shown in Figure 2:
As can be seen from Figure 2, when road surface is wider, bilateral gutter structure is adopted.The both sides of this permeable stratum structure 1 are equipped with draining earth formation 2, and such draining is faster.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
