Description

Drainage ditch with infiltration, retaining function

Technical Field

The utility model relates to a drainage structures technical field, in particular to escape canal with infiltration, retaining function.

Background

Along with the continuous acceleration of the urbanization process, the continuous amplification of impervious areas such as roads, houses and the like greatly reduces the rainfall infiltration amount, and surface runoff is obviously changed, so that the problems of urban flood disasters, serious rainwater runoff pollution and the like are indirectly caused.

Drainage ditches (comprising rain grates, linear drainage ditches and the like) mainly based on quick drainage are still the main drainage forms of hard squares, paved pavements and the like until now, and rainwater is drained to a municipal pipe network through the drainage ditches to directly or indirectly bring about environmental problems of rainwater resource waste and the like.

SUMMERY OF THE UTILITY MODEL

Based on the above problem, the utility model aims at providing a escape canal with infiltration, retaining function has drainage, infiltration, retaining function.

In order to solve the problems in the prior art, the utility model provides a technical scheme is:

a drainage ditch with functions of infiltration and water storage comprises:

the drainage ditch comprises a drainage ditch body, a drainage ditch body and a drainage pipeline, wherein the drainage ditch body is provided with a drainage channel, and the bottom of the drainage channel is provided with a permeable layer;

a plurality of inspection wells which are arranged at intervals along the length direction of the drainage ditch body, wherein the upper parts of the inspection wells are communicated to the upper part of the drainage channel, and the lower parts of the inspection wells are connected with a drainage pipe;

and the plurality of permeation pipes are arranged at intervals along the length direction of the drainage ditch body, one end of each permeation pipe extends to the permeation layer, and the other end of each permeation pipe extends to the lower part of the green belt.

Further, the drainage channel is communicated with the inspection well through an overflow pipe.

Further, the permeable layer comprises a sand layer and a gravel layer which are arranged up and down.

Furthermore, the upper part of the drainage ditch body is provided with a sewage intercepting net.

Further, the permeation tube comprises a tube body and a plurality of permeation holes arranged on the outer wall of the tube body.

Compared with the prior art, the utility model has the advantages that:

the bottom of the drainage channel is provided with a permeable layer, and the drainage channel is communicated to the inspection well, so that the drainage ditch has the functions of drainage, permeation and water storage; rainwater is consumed by permeation in light rain and is drained to a nearby green belt through the permeation pipe to supplement the underground water of the green belt, and rainwater with certain capacity can be continuously stored in the drainage ditch body and slowly released by permeation after rain; and rainwater which is not discharged before raining is discharged into the inspection well after being stored continuously, and is connected into a municipal pipe network through a drainage pipe for discharging.

Detailed Description

The above-described scheme is further illustrated below with reference to specific examples. It should be understood that these examples are for illustrative purposes and are not intended to limit the scope of the present invention. The conditions used in the examples may be further adjusted according to the conditions of the particular manufacturer, and the conditions not specified are generally the conditions in routine experiments.

Referring to fig. 1, fig. 2 and fig. 3, for the structural schematic diagram of the embodiment of the present invention provides a drainage ditch with functions of infiltration and water storage, including drainage ditch body 1, a plurality of inspection wells 2 and a plurality of permeation tubes 3, drainage ditch body 1 is arranged near hard square or road 7, drainage ditch body 1 has drainage channels 1-1, permeable layer 5 is arranged at the bottom of drainage channels 1-1, and rainwater can be infiltrated to the ground bottom.

A plurality of inspection wells 2 are arranged at intervals along the length direction of the drainage ditch body 1, the upper parts of the inspection wells 2 are communicated to the upper parts of the drainage channels 1-1, the lower parts of the inspection wells 2 are connected with drainage pipes 4, and when rainwater with certain volume is continuously stored in the drainage channels 1-1, the rainwater can overflow to the inspection wells 2 and is connected to a municipal pipe network through the drainage pipes 4 for drainage.

A plurality of infiltration pipes 3 are arranged along 1 length direction interval in escape canal body, and 3 one end of infiltration pipe extend to and permeate through layer 5 and the other end extends to greenbelt 8 below, permeates the rainwater to greenbelt 8, supplements greenbelt 8 groundwater through infiltration pipe 3.
