Description

Sponge city pedestrian path drainage system that permeates water

Technical Field

The utility model belongs to the technical field of a sponge city technique and specifically relates to a pedestrian path drainage system permeates water in sponge city.

Background

Classified according to project types, the main technical measures for sponge city construction include: the road and square projects adopt permeable pavement, biological detention zones, regulation and storage modules and the like; the park and green field projects adopt permeable pavement, grass planting ditches, rainwater gardens, ecological wetlands and the like; the buildings and districts adopt permeable pavement, rainwater gardens, high-position flower beds, green roofs and the like.

In the main technical measures for sponge city construction, the permeable sidewalk is one of the most widely applied technical measures, most of the existing permeable sidewalk designs are concerned about the permeable performance of the pavement material, and other functions of permeation, stagnation, storage and discharge are realized by facilities such as ecological tree pits, rainwater gardens or grass planting ditches outside the sidewalk, but urban roads are affected by space restriction, and most of the urban roads lack peripheral sponge facilities, so that the permeated rainwater stays between sidewalk structural layers for a long time, and the durability of the pavement structure is reduced due to accumulation of interlayer water to a certain degree, and the sponge urban pavement structure is not in line with the concept of sponge cities. Therefore, a drainage system of the sponge city permeable sidewalk needs to be designed to purposefully solve the storage and drainage of the downward-permeating rainwater.

More preferably, the drainage system is provided with a head iron wire at the joint of the transverse drainage pipe and the non-woven geotextile.

Preferably, the other end of the transverse drain pipe is connected to a rainwater manhole or a rainwater garden.

More preferably, after the transverse drainage pipe is connected to the rainwater garden, the outlet of the transverse drainage pipe is provided with a non-woven geotextile bound by iron wires.

Preferably, the longitudinal permeable pipe is a flexible permeable pipe.

Preferably, the transverse drain pipe is a PVC drain pipe.

Compared with the prior art, the utility model discloses following beneficial effect has:

firstly, the water collecting effect is better: the utility model provides a sponge city pedestrian way drainage system that permeates water adopts the formula structure of permeating entirely, and surface course, basic unit and the bed course that the surface course hydroenergy can be direct enough through the road permeate to the enhancement mode french drain downwards promptly, and good water permeability combines together with the slope about having great ease, collection surface course infiltration rainwater that can be better.

Secondly, the water storage capacity is stronger: the utility model provides a sponge city pedestrian path drainage system that permeates water is equipped with trapezoidal retaining portion to the pipe setting that will permeate water has strengthened the retaining volume greatly in trapezoidal retaining portion, carries out the drainage again after realizing effective retaining, has solved the problem of structural layer interstrational ponding, improves the durability on road surface.
