Abstract
The utility model discloses a city rail vehicle section upper cover drainage structures, upper cover are equipped with recessed escape canal, upper cover surface earthing, and escape canal department corresponds and is equipped with drainage pipe, and drainage pipe upper portion is equipped with the water inlet, and drainage pipe side lower part is equipped with drainage board and earthing contact. The drainage is carried out through the escape canal when the upper cover property is not developed, and the rainwater is discharged through the drainage pipeline after the soil is covered on the surface of the upper cover property development. Be equipped with the drainage board between drainage pipe and the earthing, still can be as the drainage of afforestation infiltration water, when the initial stage rainfall of rainstorm is great, rainwater accessible drainage board infiltration to plant roots again subducts the rainstorm peak value when playing the irrigation action to the plant. The drainage ditch can also increase the buried depth of drainage pipe, has avoided the alternately of a large amount of pipelines, makes things convenient for the development of later stage property.
Description
Technical Field
The utility model relates to a city rail vehicle section upper cover drainage structures.
Background
The upper cover of the urban rail vehicle section is a special building form, a plate-shaped structure is arranged above the urban rail vehicle section, and buildings such as houses are built above the plate-shaped structure. The drainage of the type has two working conditions to be solved, one is to cover the roof when the property is not developed, and the ground after the property is developed, so that the rainwater drainage of the roof when the property on the upper part is not developed is required to be solved, the rainwater drainage of the ground after the property is developed is also required to be solved, meanwhile, the drainage distance is basically about 300 meters, and the problem of covering soil is also required to be solved. The drainage of big roofing adopts siphon drainage usually, but city rail vehicle section upper cover development project is because covering not development simultaneously under the lid, if adopt siphon drainage, the protection to siphon fill during secondary development to and the mud during upper portion development all can produce very big hidden danger to the pipeline.
Disclosure of Invention
The utility model aims to solve the technical problem that a city rail vehicle section upper cover drainage structures is provided, the drainage problem around the upper cover is opened out to the solution.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme: the utility model provides a city rail vehicle section upper cover drainage structure, the upper cover is equipped with recessed escape canal, upper cover surface earthing, and escape canal department corresponds is equipped with drainage pipe, and drainage pipe upper portion is equipped with the water inlet, and drainage pipe side lower part is equipped with the drainage board and contacts with the earthing.
Further, a waterproof layer is laid on the surface of the upper cover.
Further, the cross-sectional dimension of the drainage ditch is 400mm multiplied by 300 mm.
The utility model discloses an useful part lies in, carries out the drainage through the escape canal when upper cover property is not developed, and after upper cover property development surface earthing, the rainwater passes through drainage pipe and discharges. Be equipped with the drainage board between drainage pipe and the earthing, still can be as the drainage of afforestation infiltration water, when the initial stage rainfall of rainstorm is great, rainwater accessible drainage board infiltration to plant roots again subducts the rainstorm peak value when playing the irrigation action to the plant. The drainage ditch can also increase the buried depth of drainage pipe, has avoided the alternately of a large amount of pipelines, makes things convenient for the development of later stage property.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:
the utility model discloses a structure is as shown in FIG. 1, a city rail vehicle section upper cover drainage structures, and upper cover 1 is equipped with recessed escape canal 2, and 1 surperficial earthing 4 of upper cover, 2 departments in escape canal correspond and are equipped with drainage pipe 3, and 3 upper portions of drainage pipe are equipped with water inlet 31, and 3 side lower parts of drainage pipe are equipped with drainage board 5 and the contact of earthing 4.
The upper cover 1 drains water through the drainage ditch 2 when the property is not developed, and rainwater is drained through the drainage pipeline 3 after the surface of the upper cover 1 for property development is covered with soil. Be equipped with water strainer plate 5 between drainage pipe 3 and the earthing 4, still can be used as the drainage of afforestation infiltration water, when torrential rain initial stage rainfall is great, rainwater accessible water strainer plate 5 infiltration to plant roots again subducts the torrential rain peak value when playing the irrigation action to the plant. The drainage ditch 2 can also increase the buried depth of the drainage pipeline 3, thereby avoiding the crossing of a large number of pipelines and facilitating the later-stage property development.
In this embodiment, a waterproof layer 6 is laid on the surface of the upper cover 1, and the cross-sectional dimension of the drainage ditch is 400mm × 300 mm.
It is to be emphasized that: the above embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form, and any simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
