The inspection well is prevented from being arranged on the driving lane, the uncomfortable feeling of driving is reduced, and the later maintenance work does not influence the use function of the motor lane.

In order to realize the purpose, the utility model is realized by the following technical scheme:

the sponge urban drainage system comprises a water collecting and seepage preventing system arranged on the side of a sidewalk, a water collecting opening arranged on a motor vehicle lane along a curb stone, a side ditch arranged between the motor vehicle lane and a non-motor vehicle lane and a drainage pipe arranged under the side road surface of the sidewalk; the water collecting opening is communicated with the side ditch, and a rainwater grate is paved on the water collecting opening; the water collecting seepage-proofing system is communicated with the side ditch through a soft water permeable pipe; the side ditch is communicated with a drain pipe.

Preferably, the water collecting anti-seepage system comprises an anti-seepage film, graded broken stones, pervious concrete, dry hard mortar and pervious bricks which are sequentially paved on the sidewalk side from bottom to top.

Preferably, a cover plate is laid on the side ditch.

Preferably, the drainage pipes are laid along the transverse direction of the road, the distance is 50-100 m, and the gradient is not less than 3%.

Preferably, the distance between the water collecting openings is 20-50 m.

The utility model has the beneficial effects that:

the utility model can realize the drainage of the existing motor vehicle lane without greatly changing the motor vehicle lane, avoids the arrangement of the inspection well of the motor vehicle lane and reduces the uncomfortable feeling of driving; the maintenance work of the later stage drainage system does not influence the use function of the motor vehicle lane.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-2, the sponge city drainage system comprises a water collecting and seepage preventing system arranged on the sidewalk side, a water collecting port 9 arranged on a motor vehicle lane along a curb 7, a side ditch 5 arranged between the motor vehicle lane and a non-motor vehicle lane and a drainage pipe 12 arranged under the pavement on the sidewalk side. Receive water prevention of seepage system includes prevention of seepage membrane 10, graded rubble 4, the concrete 3 that permeates water, dry and hard mortar 2 and the brick 1 that permeates water that lay in proper order in sidewalk roadside from the bottom up side, buries the soft pipe 11 that permeates water in 4 graded rubble underground, and soft pipe 11 that permeates water communicates with side ditch 5. The water collecting opening 9 is communicated with the side ditch 5, and the side ditch 5 is communicated with the drain pipe 12. The side ditch 5 is paved with a cover plate 6, the water collecting port 9 is paved with a rainwater grate 8, and the cover plate 6 and the rainwater grate 8 can filter large objects which are easy to block the side ditch.

When the rainwater amount is small, rainwater enters the side ditch 5 through the water permeable bricks 1, the dry and hard mortar 2, the water permeable concrete 3 and the graded broken stones 4 through the soft water permeable pipe 11; when the rainwater volume is great, the pedestrian road surface water partly gets into the side ditch 5 through the road surface, and another part sees through the surface course brick 1 that permeates water, and dry and hard mortar 2, the concrete 3 that permeates water gets into graded gravel layer 4, gets into side ditch 5 through soft formula pipe 11 that permeates water, for preventing rainwater infiltration soil matrix 13, graded gravel 4 bottom sets up one deck prevention of seepage membrane 10, and prevention of seepage membrane 10 can prevent that the rainwater from damaging soil matrix 13.

The water collecting ports 9 are arranged along the kerbstone 7 at intervals of 20-50 m, the size is 0.7m by 0.25m, the depth is 0.2-0.4 m, and the distance and the size of the water collecting ports 9 can be properly adjusted according to local rainfall. Water on the motor vehicle lane road surface is guided into the gutter 5, and drainage of the motor vehicle lane road surface is realized. By arranging the water collecting port 9 and communicating the water collecting port 9 with the side ditch 5, and communicating the side ditch 5 with the drain pipe 12 laid under the pavement of the sidewalk, the drainage of the motor vehicle lane can be realized, and the normal operation of the motor vehicle lane can not be influenced when the drainage system is maintained.

The drain pipes 12 are made of phi 110mmPE plastic pipes and are transversely paved along the pedestrian road, one drain pipe is paved at intervals of 50-100 m, and the gradient is not less than 3%. The arrangement of the distance is properly arranged according to the terrain, and the drainage effect of the drainage pipe 12 is guaranteed.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the utility model, and that, although the utility model has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the utility model as defined by the appended claims.
