Specific embodiment
In order to be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of novel rainwater cut-off equipment, including original catch-basin, original catch-basin
Side newly has a newly-increased catch-basin 140, the periphery of original catch-basin and newly-built catch-basin by the way that cover board 100 is supported to be sealed,
The inside of original catch-basin and newly-built catch-basin 140 is separated two well rooms by downflow weir 170, on the shaft bottom of original catch-basin
Side is provided with retention pipe 110, and the rainwater input end of retention pipe 110 is equipped with the dirt barrier hood 120 for intercepting bulky grain object, increases rainwater newly
The surface of well 140 is connected with effluent outfall 190 by fixing device, and flashboard is equipped at the nozzle of effluent outfall 190
180, the surface of downflow weir 170 is provided with pre-embedded steel slab 173, and the centre of pre-embedded steel slab 173 is equipped with plastic cement plate washer 172, plastic cement
The surface of plate washer 172 offers spout hole 171.
In addition, the material that support cover board 100 uses is concrete.The surface of original catch-basin is connected by fixed locking device
It is connected to rain pipe import 130.Detachable connection, flashboard 180 and sewage discharge are used between flashboard 180 and effluent outfall 190
The junction of pipe 190 is provided with adjusting screw.The top of newly-increased catch-basin 140 is equipped with cast iron flat 150, increases catch-basin newly
The stepping ladder 160 convenient for safeguarding is offered on 140 inner wall.The height of downflow weir 170 highly has three points for original catch-basin
One of.The height of newly-increased catch-basin 140 is flushed in ground surface.
Catch-basin shut off renovation technique be by the transformation to catch-basin, by original catch-basin create a well, be used in combination
Downflow weir separates two well rooms, and two wells are connected respectively with sewage network and Storm Sewer Network, by high process control to rainwater into
Row shunting, the higher initial rainwater of pollutant concentration will be trapped to sewerage, and remaining rainwater will pass through downflow weir overflow
To storm-water system.
Entire closure works system is by catch-basin, existing rain pipe, existing sewage pipe, intercepting sewer, dirt barrier hood, downflow weir, overflow
Hole, flashboard (can not set) composition.After catchment occurs, initial rainwater enters catch-basin by existing rain pipe, due to shutting off
Certain height difference is equipped between pipe and shaft bottom, initial rainwater can be precipitated first, and after rainfall gradually increases, the rainwater after precipitation can be by cutting
Flow tube enters storm-water system, and big particulate matter can be intercepted by trash rack and be deposited in shaft bottom；If rainfall further increases, rainwater can lead to
The well room that spout hole enters right side is crossed, hence into storm-water system；When rainfall is excessive, when overflow port has little time draining, rainwater can
It is turned over by downflow weir into storm-water system, rainwater at this time is more clean.
The effect of flashboard：By adjusting flashboard control into the water of sewerage, if flashboard fully opens, rainwater meeting
Sewerage is fully entered, unless rainfall is excessive, has little time to arrange, downflow weir overflow can be passed through.If local sewage plant load compared with
Greatly, then it needs to set flashboard, stringent control enters the water of sewerage.
Using existing storm-water system and sewerage, initial rainwater is cut sewerage, is controlled by downflow weir so that
More clean rainwater enters storm-water system after precipitation of shutting off.
The beneficial effects of the utility model are：Junction structure is simple, without external impetus, by existing storm-water system and dirt
Water system is combined, and is shut off to initial rainwater；Cost is relatively low；Application region is wider, old city, business plot
It is used, practical performance is excellent, novel in design, is a kind of good innovation scheme.
It should be understood by those skilled in the art that the present utility model is not limited to the above embodiments, above-described embodiment and
The principle for only illustrating the utility model described in specification, on the premise of not departing from the spirit and scope of the utility model originally
Utility model also has various changes and modifications, and these various changes and improvements fall within the scope of the claimed invention.
The utility model requires protection scope is defined by appended claims and its equivalent.
