Description

Overhead road surface inlet for stom water collects the method for rainwater installation and Collection utilization rainwater
Technical field
The present invention relates to rainwater catchment system, be specifically related to the method that overhead road surface inlet for stom water collects rainwater installation and Collection utilization rainwater.
Background technology
Urban rainwater collection utilizes, and has both saved municipal water use, alleviates again city flood damage and threatens.In urban rail transit construction, to the rainwater catchment system at station, overhead road surface, can effectively limit bridge floor storm-water drainage and loss, control rainwater runoff pollution around elevated line, also meet urban water conservation policy, build the trend of the theory of green subway and sponge urban construction.
In the Collection utilization process of rainwater, early-stage rainwater (amount of precipitation of front 2mm or 5 minute) water quality is poor, the rainwater of initial rainfall should be abandoned, and collects the rainwater of comparatively clean intermediary and later stages rainfall.In current rain water collecting system, flow abandoning apparatus mainly contains two kinds, and a kind of use electric energy, adopts automatic control module, by detecting the abandoned stream amount of rainfall of Rainwater Quality or the setting of collecting, controls abandoned stream, collection start and stop; Another kind of mechanical rainwater flow-discarding device, controls built-in float valve by amount of rainfall size and controls abandoned stream, collects start and stop, though this kind of device does not need electric energy, volume is comparatively large, complex structure.Track traffic on the ground elevated station rainwater-collecting need be arranged along viaduct, and bleeding point is more.If use above-mentioned flow abandoning apparatus, have following problem:
1, the flow abandoning apparatus complex structure of system for reclaiming rainwater;
2, the rainwater of initial stage collection contains the dirts such as a large amount of silts;
3, rainwater-collecting and treating capacity are comparatively large, and rainwater reuse cost is higher;
The factors such as 4, rainwater flow-discarding device is poor by outdoor environment, automatic control module is fragile affect, and system maintenance is complicated.
Therefore, a kind of collection rainwater installation for overhead road surface inlet for stom water is needed.
Summary of the invention
Overhead road surface that the object of this invention is to provide a kind of rainwater catchment system for inlet for stom water place, overhead road surface, that rainwater recycle is with low cost inlet for stom water collects the method for rainwater installation and Collection utilization rainwater.
In order to reach above-mentioned purpose, the present invention adopts following technical scheme:
Overhead road surface inlet for stom water collects rainwater installation, comprise the inlet for stom water be located in the structural slab of overhead road surface, in inlet for stom water, be provided with the abandoned stream roof drain for converging early-stage rainwater, the top of abandoned stream roof drain is provided with collection roof drain, and collects the bridge floor of roof drain higher than overhead road surface; Be connected with municipal pipe by outer mozzle bottom abandoned stream roof drain, the interior pipe collected bottom roof drain is connected with rain collector, interior pipe is through abandoned stream roof drain, and abandoned stream roof drain is used for early-stage rainwater and bottom contain more polymictic rainwater catchment and import municipal Storm Sewer Network; Collect roof drain to be used for when bridge floor rainfall runoff height is greater than 3mm, collect comparatively clean rainwater.
Further, when rainwater is more, cleaner rainwater enters to be collected in roof drain.
Further, described collection roof drain is higher than the bridge floor 2mm ~ 4mm on overhead road surface.
Further, described outer flow-directing shroud is in the outside of described Inner guide pipe, and the rain water drainage mouth of pipe for being connected with municipal pipe is located at the side of outer mozzle.
Further, described collection roof drain and described air-flow inlet for stom water are siphon rainwater head.
Further, be provided with the barrier for filtering contaminants in the surrounding of described abandoned stream roof drain, barrier be obliquely installed and the top of barrier towards the vertical center line of abandoned stream roof drain.
Further, described Inner guide pipe and described outer mozzle are structure as a whole, and the two forms mozzle, and mozzle and overhead road surface structural slab are fixed.
Further, described collection roof drain comprises kuppe and pressing plate, and the surrounding of kuppe is with multiple rectification mouth, and the bottom of kuppe is located at by pressing plate, and pressing plate is fixed by the top of fastener and abandoned stream roof drain, and the bottom of pressing plate is provided with interior pipe.
Abandoned stream roof drain comprises kuppe and pressing plate, and the surrounding of kuppe is with multiple rectification mouth, and the bottom of kuppe is located at by pressing plate, and pressing plate and overhead road surface structural slab are fixed.
Further, the surrounding of described inlet for stom water is obliquely installed to ensure that rainwater flows in described abandoned stream roof drain smoothly.
Further, described fastener is bolt and nut, and bolt is adjustable-height bolt.
The method of overhead road surface Collection utilization rainwater, concrete steps are as follows:
1) on overhead road surface, an inlet for stom water lower than bridge floor surface layer is set at interval of setpoint distance;
2) vertically arrange two roof drains up and down at inlet for stom water, these two roof drains are coaxially arranged, and the roof drain of top is higher than bridge floor surface layer;
3) be provided with the pipeline through below roof drain bottom the roof drain above, this pipeline is connected for collecting clean rainwater with rain collector;
4) pipeline and rainwater municipal administration pipeline connection is provided with bottom the roof drain below.
Operating principle of the present invention is: utilize the roof drain that two highly different, and the roof drain of lower is used for the abandoned stream of rainwater, and the roof drain of eminence is used for the collection of rainwater by mozzle; And the size of collecting roof drain is less than the size of abandoned stream roof drain, is more convenient for the collection of rainwater, meets the flowing law at inlet for stom water of rainwater.
The invention has the beneficial effects as follows:
1, rational in infrastructure, simple, easy to assembly, non-maintaining.
2, change original rainwater first collects underground abandoned stream again mode from road surface, carry out abandoned stream from rainwater-collecting source to early-stage rainwater and the dirtier rainwater of bottom, decrease rainwater flow-discarding device in original rain water collecting system, reduce cost.
3, the rainwater by collecting roof drain is cleaner, decreases the burden of the filter before hydrotreater, realizes rainwater recycle and utilizes.
4, abandoned stream and collection are carried out to rainwater from the starting stage, decrease the water yield of rainwater-collecting and process, reduce rainwater recycle cost.
5, pass through abandoned stream type roof drain to rainwater selective collection at roofing, only have the clean rainwater in rainfall later stage to enter system for reclaiming rainwater, reduce the volume of rainwater-collecting module, hydrotreater, filtered water tank, provide cost savings.
