Abstract

The utility model provides a drainage ditch cover plate, comprising cover plate main bodies, wherein the bottom surface of each cover plate main body is placed on a drainage ditch; the upper surface of each cover plate main body is provided with a flow buffer groove for temporarily storing water; and the water on the road surface can be collected into the flow buffer grooves. Gaps are arranged at two ends of each cover plate main body; when a plurality of cover plate main bodies are connected end to end, the adjacent gaps are mutually fastened to form discharge holes; and the water in the flow buffer grooves is discharged through the discharge holes into the drainage ditch. The flow buffer grooves are located at the middle parts of the cover plate main bodies, and are arranged along the axial directions of the cover plate main bodies; when the plurality of cover plate main bodies are connected end by end, the flow buffer grooves are connected to be a water drainage flow passage. Ribs are arranged on two sides of each cover plate main body; the flow buffer grooves are located between the ribs; and the ribs are used to prevent the water overflowing from the flow buffer grooves. The upper surfaces of the ribs are leveled with the road surface. The bottom parts of the flow buffer grooves are planes; and inclined planes are arranged at joints between the ribs and the flow buffer grooves. As the flow buffer grooves are arranged on the upper surfaces of the drainage ditch cover plates, and the water on the road surface is collected into the flow buffer grooves, then flows to the drainage ditch through the discharge holes, and the reduction of road surface gathered water can be facilitated.

Description

A kind of drainage ditch cover plate
Technical field
The utility model relates to drainage, relates in particular to a kind of drainage ditch cover plate.
Background technology
Urban sewerage and drainage refers to that city domestic sewage, industrial wastewater, Atmospheric precipitation (containing rain, snow-broth) runoff and other abandon collection, conveying, purification, utilization and the discharging of water.The sanitary sewage and the industrial wastewater that contain pollutant, the common name municipal sewage.Municipal sewage generally is transported to the municipal sewage plant by urban drainage pipe network and purifies, reach the water quality standard of regulation after, be used again or enter water body.The urban sewerage and drainage facility is to guarantee the eliminating of urban ground water, prevents and treats municipal water and pollutes, and make the city water resource protection be able to eucyclic requisite infrastructure.Because function and the characteristic of urban sewerage and drainage facility make its project scale large, investment cost is large, and difficulty of construction is large, long in time limit and be in operation the consumption a large amount of energy and resource.Before social economy not yet attained full development, the city often was difficult for accomplishing to have perfect drainage and good water environment.Majority is too to utilize natural purifying ability, causes the pollution of water environment.
Urban sewerage and drainage system is divided into separated drainage system and combined drainage system.When sanitary sewage, industrial wastewater, precipitation runoff compile with two or more sewer system and carry, be called separated drainage system.The system that wherein compiles production waste in sanitary sewage and the industrial wastewater is called the sewage removal system, compile and drain precipitation runoff and do not need the system of industrial wastewater to be processed to be called the rainwater removal system, that only gets rid of industrial wastewater is called the industrial wastewater removal system.The combined drainage system that is called that sanitary sewage, industrial wastewater and precipitation is compiled conveying with a pipe-line system.It is divided into again direct-discharging combined drainage system and shutoff type combined drainage system.Shutoff type drainage system pipe-line system general designation overfall facility is in order to the water yield of limit transport to local Wastewater Treatment Plant.Because the rainwater that overflows also enters the river course nearby, therefore from water yield angle, the shutoff type combined drainage system is actually identical for the impact of drainage with the segregation system storm-water system.
Precipitation runoff refers to that runoff in ground rainwater and ice dissolution water, claims again rainfall runoff.The water quality of precipitation runoff is relevant with the ground surface situation of runoff.Generally comparatively clean, but the early-stage rainwater runoff is messy.The rainfall runoff time concentrates, measures large, and is maximum with storm runoff harm.Rainfall runoff on the road surface generally flows directly in the gutter, and when rainfall is excessive, tends to slowly cause surface gathered water owing to the gutter water inlet, affects the normal operation of road traffic.Therefore, be necessary the structure in gutter is improved, to prevent that surface gathered water is too much when raining heavyly.
The utility model content
The purpose of this utility model provides a kind of drainage ditch cover plate, so that large flow rainwater flows into the gutter as early as possible, reduces surface gathered water.
The utility model is that the technical scheme that its technical problem of solution adopts is,
A kind of drainage ditch cover plate comprises cover board body, and the bottom surface of cover board body places on the gutter, and the upper surface of cover board body has the temporary transient unhurried current groove that stores that supplies water, and the water on the road surface can be gathered in this unhurried current groove.
The cover board body two ends have breach, and when a plurality of cover board bodies were end to end, the mutual snapping of adjacent breach formed discharge orifice, and the ponding in the unhurried current groove flows into the gutter from this discharge orifice.
The unhurried current groove is positioned at the middle part of cover board body, and along the axial setting of cover board body, when a plurality of cover board bodies were end to end, the unhurried current groove was connected to become the draining runner.
The cover board body both sides have fin, and the unhurried current groove is between fin, and the water that fin prevents from flowing slowly in the groove overflows.
The upper surface of fin flushes with the road surface.
The unhurried current trench bottom is the plane, and fin has the inclined plane with the joint of unhurried current groove.
The utility model has the advantage of, this drainage ditch cover plate thereon surface is provided with the unhurried current groove, and the fin of its both sides flushes with the road surface, and the water on road surface flows into the gutter from discharge orifice after entering in the unhurried current groove again, water on the unhurried current groove road pavement is stored temporarily, is conducive to reduce surface gathered water.
Description of drawings
Fig. 1 is the structural representation of the drainage ditch cover plate that the utility model proposes.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, the drainage ditch cover plate that the utility model proposes comprises cover board body 1, and the bottom surface of cover board body 1 places on the gutter, and the upper surface of cover board body 1 has the temporary transient unhurried current groove 2 that stores that supplies water, and the water on the road surface can be gathered in the unhurried current groove 2.
Cover board body 1 two ends have breach 3, and when a plurality of cover board body 1 was end to end, adjacent breach 3 mutual snappings formed discharge orifices 4, and the ponding in the unhurried current groove 2 flows into the gutter from discharge orifice 4.
Unhurried current groove 2 is positioned at the middle part of cover board body 1, and along the axial setting of cover board body 1, when a plurality of cover board body 1 was end to end, unhurried current groove 2 was connected to become the draining runner.
The both sides of cover board body 1 have fin 5, and unhurried current groove 2 is between fin 5, and the water that fin 5 can prevent from flowing slowly in the groove 2 overflows.
