Description
Technical field
The present invention relates to hydrocone type Stormwater Drainage System, specifically a kind of skyscraper is arranged with PVC rain pipe siphon
Water is anti-to inhale flat pressure relief device.
Background technique
Gravity drainage system is traditional roof drainage mode.Simple, the safe and reliable to operation spy with design and construction
Point.The standpipe through connecing under roof drain is discharged by flow by gravity after rainwater is collected by terrace gutter.This systematic pipeline can not be by
Water is completely filled with.When water is flowed down along standpipe tube wall, only accounts for a part of standpipe section under normal circumstances or even sub-fraction is
Water, a part are air.The disadvantage is that pipeline setting is relatively more, the position that takes up space is more.
Hydrocone type Stormwater Drainage System is the freely falling body using rain leader downspout water column in flowing full to storm sewer
System column pipe, roof drain generate suction force, and the conventional rainwater for leaning on gravity stream is made to become kinetic current rainwater, to accelerate rainwater row
It puts, reduces the specification of rain leader downspout, reduce the quantity of rain leader downspout, reducing the construction costs.The pipeline used in building at present
Specification is generally two kinds of bores of diameter 110mm or diameter 160mm.
The pipeline drop of skyscraper is larger, distance is longer.And common buildings can generally use co-layer draining, same layer at present
Draining is mostly transverse pipe, manage in easy ponding, have negative pressure in siphon rainwater drainage system pipeline, maximum be located at horizontal transverse-pipe with
Standpipe intersection.Especially in ground floor, when meeting with when raining heavyly, the water in rainwater pipeline substantially remains in full state.Meanwhile
Siphon rain pipe, rain pipe are all full-section pipe-flow under normal circumstances, and in bottom, amplification No.1 is the flow velocity in order to increase top standpipe,
To play siphonage, so that roof drain accelerates draining.At this point, due to long range rain leader downspout from top to bottom when pipeline in
Sometimes or there is part to occupy for air, allow for pipe content in this way and easily form negative pressure of vacuum.As relatively thin in script tube wall
It is vacuumized in pipeline, so that tubing is very easy flat by suction.Here it is in recent years, when encountering heavy rain, shape is easy in pipeline
At vacuum, lead to the main reason for rainwater tubing is by suction flat explosion.If according to this require if, be computed should use arrive
The tubing of PN6 grade, because its resistance to pressure-reduction level can achieve vacuum pressure, it can be ensured that be not in take out flat phenomenon.
According to siphon principle, when liquid level height difference is bigger, water velocity is bigger in plastic tube, drains rapider.Using building
It builds object roofing height and is formed by head to realize siphon drainage.When rainfall is smaller, siphonic system is also only as gravity stream.
When rainfall reaches moderate rain, tail pipe reaches siphon condition full of water, so that whole system is generated siphon, becomes siphon jet.And
When rainfall reaches heavy rain even heavy rain, roof ponding reach a certain height, and tail pipe reaches siphon condition full of water, then makes whole
A system generates siphon, can make rainwater quick drain.Siphon drainage flow velocity is very big at this time, to be discharged into cell rain again by transverse tube
Well.Drainage pipeline generates negative pressure when rainwater passes through pipeline reducing diameter in flowing full state here in system, accelerates rainwater
Mass rate of emission, siphonic system at this time come into pressure current.And the section of tubing of entire standpipe is by horizontal in co-layer draining sometimes
Pipe influences, wherein partial air can be generated, the pressure initiation of negative pressure of vacuum and is gradually increased at this time.Then, wall thickness is relatively thin
Rainwater tubing is inhaled flat.Under normal circumstances, in the draining of hydrocone type rain pipe, the materials such as common PVC plastic tube are not because wall thickness is up to
To the design requirement for needing pressure-bearing, then it will appear the case where negative pressuren zone is crushed.Especially skyscraper, storm-water system are big
Mostly use cast iron pipe, pressure-bearing plastic pipe, steel-plastics composite pipe, the thicker material of the wall thickness such as stainless steel tube.Cause overall cost become compared with
For valuableness, while because of the intrinsic propesties of a variety of materials, installation and maintenance are also more inconvenient.
