Furthermore, the drainage blind ditch 4 is made of pervious concrete, and the lower part of the drainage blind ditch is provided with a gravel cushion layer.

Further, the water seepage pipes 5 are arranged in a net shape, and the pipe diameters and the intervals of the water seepage pipes 5 are determined according to the rainfall amount.

Further, the manhole 10 is made of pervious concrete, and a gravel cushion is arranged at the lower part of the manhole. The manhole itself has a penetration function, and rainwater can be penetrated to the periphery and the lower part.

Further, the cross section of the drainage underdrain 4 is U-shaped.

Furthermore, an access well cover plate and a water seepage layer are arranged above the access well.

The utility model has the advantages of:

1. the utility model provides a pair of outdoor parking area drainage system through set up recessed greenery patches at the parking area periphery, sets up the drainage blind ditch in the green below of recessed to and set up the infiltration pipe in the parking area below, with the filtration of parking area rainwater through recessed greenery patches and drainage layer, reduced the pollutant of rainwater in earlier stage, alleviate the influence to groundwater quality of water.

2. The rainwater permeates into the underground through the drainage blind ditches and the permeation pipes and is not influenced by a ground paving method. And the penetration pipe is positioned below the ground of the parking lot, the depth can be adjusted according to factors such as load, frozen soil depth, soil quality and rainfall, and the application range, the rainwater permeability and the durability of the parking lot are improved.

3. The technical scheme of the utility model can be applied to all kinds of outdoor parking areas, increased ability such as rainwater infiltration, purification, delay, save, alleviateed municipal rainwater pipe network pressure, effectively supplemented groundwater.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is further described with reference to fig. 1-3.

The utility model provides an outdoor parking lot drainage system, the system includes parking stall ground 1, curb 2, recessed formula greenery patches 3, drainage blind ditch 4, infiltration pipe 5, overflow pipe 6, drainage layer 7, geotechnological cloth 8, drainage blind ditch apron 9 and access well 10, parking stall ground 1, be used for parking the vehicle on it, the edge in parking stall is equipped with curb 2, the parking stall periphery still is equipped with recessed formula greenery patches 3, drainage blind ditch 4 is located recessed formula greenery patches 3 below, drainage blind ditch 4 upper portion is provided with drainage blind ditch apron 9 and drainage layer 7, infiltration pipe 5 arranges below parking stall ground 1, infiltration pipe 5 is connected with drainage blind ditch 4, be equipped with the metalling around infiltration pipe 5, access well 10 establishes at the intersection or the turn of drainage blind ditch 4, or slope change, or every certain distance on the straightway, be convenient for later stage inspection, the maintenance, the overflow pipe 6 is arranged at the highest water level of the concave greenbelt 3 and is communicated with the municipal rainwater pipe network. When the rainfall is too large to exceed the maximum water storage capacity of the system, the redundant rainwater is discharged to the municipal rainwater pipe network through the overflow pipe 6.
