Description

Permeable drainage structure for pavement

Technical Field

The utility model relates to a road surface drainage technique that permeates water, especially a road surface drainage structures that permeates water.

Background

The road surface is a layered structure that is laid on a road bed with various road building materials and directly bears the load of vehicles. The pavement with good quality has enough strength and good stability, and the surface of the pavement can meet the requirements of smoothness, compactness and skid resistance. The road surface structure comprises surface course, basic unit and bed course, and the purpose of road surface drainage requires that highway and urban road at all levels should set up necessary drainage facility according to the concrete condition on local precipitation and road surface to properly select the spatial arrangement form and the structure on road surface, in time with precipitation discharge road surface, prevent that surface ponding from permeating inside the road surface, even the road bed, guarantee driving safety. The high-grade road surface water that the driving speed is fast should be got rid of rapidly to prevent that the road surface from forming the water film and influencing driving safety, but the drainage structures of permeating water on present road surface has the structure complicacy, and the not good problem of result of use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a road surface drainage structures that permeates water for there is the structure complicacy in the solution now, and the not good problem of result of use.

In order to solve the problem, the utility model provides a road surface drainage structures that permeates water, including road surface, husky base brick and the concrete layer of permeating water, the upper end that husky base brick was permeated water is provided with the road surface, it is provided with the clearance to permeate water between the brick to husky base, the below that husky base brick was permeated water is concrete layer, the bottom that husky base brick was permeated water has the water seepage layer, concrete layer has laid the slope near one side of water seepage layer, slope surface packing has the grains of sand, the drain pipe is installed to the bottom on slope, install the sealing washer between drain pipe and the slope, the outside of drain pipe is equipped with the barrier layer, the below of barrier layer is the foundation course.

The utility model provides a road surface drainage structures that permeates water still has following technical characteristic:

further, stone rice carpets are paved on the surface of the pavement.

Further, the material of slope is marble, the surface texture of slope is smooth.

Furthermore, the tail end of the drain pipe is externally connected with a drain channel.

Further, the diameter of the gaps between the sand-based water permeable bricks is 3mm to 6 mm.

The utility model discloses following beneficial effect has: stone rice carpet has been laid through the surface on road surface to and the road surface bottom is provided with sand base brick that permeates water, can alleviate urban drainage and flood control pressure, pollution and the treatment sewage that prevents public waters have good effect, make not ponding on the road, the rainwater passes through infiltration layer and grains of sand, flow into the drain pipe along the slope gathering, drain pipe intercommunication drainage canal, finally flow to appointed waters, and the bottom of drain pipe is provided with the barrier layer, prevent rainwater infiltration subbase, thereby lead to a large amount of ponding to get into the foundation course.
