Description

Sponge urban water infiltration drainage device

Technical Field

The utility model relates to a city infrastructure equipment technical field specifically indicates a sponge city water infiltration drainage device.

Background

In the urban development process, a large amount of land is hardened, the ecology is unbalanced, and in addition, the rainwater drainage facility is not enough to be matched, the capacity is small, the layout is unreasonable, the innovation means is not enough, and the urban inland inundation phenomenon is prominent, the life and property safety of the masses is harmed, and the urban development image is damaged. In addition, the existing drainage system basically adopts pipelines to drain, and when water flows through the pipelines suddenly, the drainage capacity of the pipelines is limited, so that urban waterlogging is easily caused.

Along with the development of domestic economy in recent years, the capital investment of the country on road infrastructure is more and more, the capital investment is less for the construction of a rural road network and more for the construction of an expressway and a railway track, whether the firm and reliable performance of the economic infrastructure is related to the civil problem for a long time in the future, particularly, the capital investment of various maintenance, reconstruction and expansion and the like still exists every year after the construction is completed, the maintenance cost is increased year by year when the base number of road infrastructure is increased, particularly, the precipitation is large in southern areas of China, the sand in rivers and rivers is more, the bearing effect of a roadbed can be seriously influenced by long-time erosion and scouring of rainwater, the reliable service life of the road is prolonged, the traditional road drainage system is that a water diversion channel is excavated beside the road, but the water diversion channel can take away a large amount of roadbed soil under the scouring of rainwater, the maintenance cost is increased, and the safe service life of the road is also seriously influenced, therefore, how to improve the strengthened foundation pavement and increase the reliability of the roadbed and reduce the influence of precipitation on the roadbed is a problem which needs to be solved urgently at present.

Although the existing drainage device can realize seepage drainage, the water in the drainage device cannot be effectively prevented from flowing back to a road, so that the actual drainage effect has some defects, and improvement is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming above technical defect, providing a sponge city water infiltration drainage device, infiltration drainage is effectual, prolongs the life of road.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a sponge urban water infiltration drainage device, includes drain pipe and filter layer, the filter layer surround the drain pipe outside, the filter layer include filter screen layer, gravel layer and infiltration cotton layer, the thickness on gravel layer be 9-10cm, the thickness on infiltration cotton layer be 0.9-1cm, the drain pipe be the corrugate pipeline that has the fold, the drain pipe on the equipartition have the inlet opening, inlet opening department articulated be connected with the apron, the apron be towards the inboard direction one-way apron structure that opens and shuts of drain pipe.

Furthermore, the filter layer is composed of three filter screen winding drums which are overlapped in a staggered mode, and the filter screen winding drums are provided with honeycomb-shaped meshes.

Furthermore, the filter screen layer, the sand stone layer and the water seepage cotton layer are sequentially arranged on the outer side of the drain pipe from outside to inside.

Furthermore, the cover plate is hinged to one end of the inner wall of the drain pipe, which is close to the water inlet hole, through a hinge.

Furthermore, the cover plate is embedded at the water inlet, and a rubber layer is arranged on the periphery of the cover plate.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses can reduce the road bed water content, reduce the erosion of water to the road bed, effectively avoid the water reflux in the drainage device simultaneously, guarantee the effect of infiltration drainage.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic structural view of the drain pipe of the present invention.

Fig. 3 is a schematic structural diagram of the cover plate of the present invention.

As shown in the figure: 1. the water draining pipe comprises a water draining pipe body, a filtering net layer, a sand stone layer, a water seepage cotton layer, a water inlet hole, a cover plate and a water draining pipe body, wherein the water draining pipe body comprises 2 parts of a filtering net layer, 3 parts of a sand stone layer, 4 parts of a water seepage cotton layer, 5 parts of a water inlet hole, 6 parts of a cover plate.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a sponge urban water infiltration drainage device, includes drain pipe 1 and filter layer, the filter layer encircle in the drain pipe 1 outside, the filter layer include filter screen layer 2, grit layer 3 and the cotton layer 4 of infiltration, the thickness of grit layer 3 be 9-10cm, the thickness of the cotton layer 4 of infiltration be 0.9-1cm, drain pipe 1 be the corrugate pipeline that has the fold, drain pipe 1 on the equipartition have inlet opening 5, 5 articulated being connected with apron 6 of inlet opening, apron 6 be towards the one-way apron structure that opens and shuts of the inboard direction of drain pipe 1.

The filter layer 2 is composed of three layers of filter screen winding drums which are overlapped in a staggered mode, and the filter screen winding drums are provided with honeycomb-shaped meshes.

The filter screen layer 2, the sand layer 3 and the water seepage cotton layer 4 are sequentially arranged outside the drain pipe 1 from outside to inside.
