Description
Technical field
The utility model relates to drainage system against rain, specifically, relates to a kind of siphonic roof storm system.
Background technology
For many years, China adopts gravity flow system to solve the storm-water drainage of building always, but the configuration of system and fluidised form have limited the function and the effect of storm-water system, standpipe is many, caliber is thick, emission effect is poor, be difficult to satisfy the requirement of modern architecture, even if reached the requirement of building storm-water drainage, also a lot of valuable architectural spaces of respective outer side edges that will obtain building so that waste are to adapt to it.
The application characteristic of tradition gravity current storm-water system is:
1, a large amount of rain leader downspout.
2, the roof drain of a greater number.
3, the level set water pipe is installed will certain gradient.
4, bigger caliber.
5, ground excavation work on a large scale.
6, more rainwater inspection well.
7, more rainwater goes out the family pipe.
8, inspection hole or clean out need be set.
9, the preceding depth of water of higher bucket is arranged near the roof drain.
10, the roof drain limited amount system of same standpipe.
11, being not easy to electrical and mechanical comprehensive in dynamo-electric installing space coordinates.
12, the roof drain of different level aspect should not insert same system.
Along with development of times, building scale of construction profile and function huge variation has taken place, the building storm-water drainage that gravity rainwater design concept and device can not solve some super large roofings, labyrinth better, more especially rainwater is gone out the quantity of family pipe and the building that there are special requirement the position, and some are because the building of gravity storm-water system intractable is adopted in the indoor function restriction of building.
In traditional gravity current storm-water system, to be helical form flow downward along the inside pipe wall of standpipe rainwater.In the ordinary course of things, about 1/3 of pipeline cross section is a rainwater, and about 2/3 is air.In theory,, use 1/3 size of traditional storm sewer so, just can drain identical rainwater if remove air in the pipeline.
The application of hydrocone type rain water on roof exhaust system has solved the problems that the gravity storm-water system cann't be solved or be difficult to solve, the space of its drainage effect and system pipeline arrange be the gravity storm-water system can not compare.
The utility model content
The purpose of this utility model provides a kind of siphon type rainwater discharging system.
The inside of any one siphonic system connect must be closely, all linked with one another, the situation that does not allow any disconnection or gas leakage occurs.And satisfy following condition:
(1) certain height difference Δ h (having enough heads to utilize) is arranged between water inlet and the outfall.
(2) be full of water in the pipeline.
(3) flow velocity of all standpipe part water is greater than 2.2m/s.
(4) flow velocity of all level set water pipe part water is greater than 1.0m/s.
(5) negative pressure in the pipeline needs greater than evaporation of water pressure.
In order to realize the purpose of this utility model, the siphonic roof storm system that the utility model provides comprises hydrocone type roof drain, tail pipe, level set water pipe and standpipe.Described hydrocone type roof drain comprises water conservancy diversion gas barrier and base.Whole drainage system is close-connected one.
The rainwater that the hydrocone type roof drain of different level aspect is gathered flows into same standpipe through pipeline, the pipeline turning radius should be not less than 4 times of pipe diameters in the described pipeline, threeway is 45 degree skew Ts, can reduce the resistance of pipeline to current, guarantees the flow velocity of current in the pipeline.
The water conservancy diversion gas barrier contains top board, several lower floor's fins radially that top board has a downward extension, each lower floor's fin forms water inlet with the circumferential arrangement of a determining deviation along top board, the top board upside is provided with from top board middle part the radially upper strata fin of top board edge and circumferential arrangement, with the rainwater drainage to water inlet.
Water conservancy diversion gas barrier diameter is preferably 0.21～0.23m, and base diameter is preferably 0.23～0.25m.When roofing was reinforced concrete structure, described hydrocone type roof drain also comprised the waterproof platen, is installed between water conservancy diversion gas barrier and the base.
Hydrocone type roof drain size described in the utility model is littler, can well reduce when installing the destruction to building.
Make waterproof roll and base install closely.
Described tail pipe height is preferably 0.20～2.00m.
In the roofing siphon type rainwater discharging system, need the close fit of designing institute, wherein the design of gutter and tail pipe (the standpipe section that the discrepancy in elevation be connected of roof drain drain gully to the horizontal transverse tube pipe) is improper, can cause direct influence to system.Gutter is set is the rainwater of collecting roofing for rational and effective, and the design of tail pipe is with collected rainwater introduction pipeline system and be full of pipeline gradually and produce siphon safely.
When rainfall comes temporarily, tail pipe produces siphon earlier, and water begins to be full of system, is filled and time of producing siphon is called the time of being full of up to system thus.Because the drainability the when drainability of tail pipe produces siphon than whole system is little, water can gather in gutter up to siphon and produce.Therefore, the design of gutter will have enough volumes.Because the time that is full of of the drainability decision systems of tail pipe, if tail pipe is short more, its drainability is just low more, needed be full of the time will be long more, and the rainwater in the gutter will gather manyly more.Therefore the short more required gutter volume of tail pipe will be big more.The tail pipe height can determine the gutter volume.
Support of pipelines is established at position that pipeline is turned in the system pipeline and the two ends that the position of threeway occurs.Establish support of pipelines on the level set water pipe, the support of pipelines spacing is 0.5～2.0m.Establish support of pipelines on the standpipe, the support of pipelines spacing is 0.75～2.5m.Can better fix this drainage system of protection.
Described drainage system preferably adopts hdpe pipe.
The hydrocone type roof drain is under same discharge capacity in the siphonic roof storm system that the utility model relates to, water conservancy diversion gas barrier and base size are far smaller than like product, and a parts water conservancy diversion gas barrier just can be accomplished the effect of water conservancy diversion trapping and obstruct foreign material, install very convenient, attractive in appearance, especially easier to be hidden in accessible roof.In work progress, the installation of native system is less to the roofing dimensional requirement that punches, and makes the negative effect that building system is caused reduce to minimum.Be widely used in various types of industry and civilian construction in this drainage system.Compare with traditional gravity storm-water system, have following clear superiority:
1, a spot of rain leader downspout.
2, the roof drain of lesser amt.
3, the level set water pipe is installed does not need the gradient.
4, less caliber.
5, work is excavated on minimum ground.
6, minimum rainwater inspection well.
7, more rainwater goes out the family pipe.
8, do not need to be provided with inspection hole or clean out.
9, the depth of water is lower before near the bucket that has the roof drain.
10, the roof drain quantity of same standpipe without limits.
11, being convenient to electrical and mechanical comprehensive in dynamo-electric installing space coordinates.
12, the roof drain of different level aspect can insert same system.
