Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and examples.
Shown in referring to Fig.1~Fig. 3, the hydrocone type rain for overpass in one embodiment provided by the invention drains system
System, including hydrocone type rain perforaled strainer 1, column pipe 2, standpipe 3 and receipts well 4, multiple hydrocone type rain perforaled strainers 1 are along bridge floor road two
The gutter of side is set gradually, and the lower end water outlet of multiple hydrocone type rain perforaled strainers 1 passes through the upper end with standpipe 3 respectively of column pipe 2
Connection, the lower end of standpipe 3 are connect with well 4 is received, and are received well 4 and are set to the ground below overpass；Receive well 4 with municipal rain
Pipe network connection；Using the potential energy of bridge floor height and standpipe 3 water outlet height difference, when rainwater flows in series through column pipe 2 and falls
Siphonage is formed, and generates peak suction at this, rainwater is discharged under the suction of negative pressure with higher speed in pipeline
Bridge floor.
Further, hydrocone type rain perforaled strainer 1 includes hydrocone type roof drain 5, riffler 6 and cover board 7, hydrocone type roof drain
5 are set in riffler 6, and cover board 7 is set to the upper end of riffler 6.
Further, the top of cover board 7 is equal with surrounding bridge floor, or slightly below bridge floor.
Further, the bottom surrounding of the riffler 6 is toward intermediate, inclined；To guarantee that rainwater can faster flood hydrocone type rain
Bucket 5, it is possible to reduce air entrainment in water creates more favorable condition for the draining of hydrocone type rain.
Further, multiple deflectors are distributed on the hydrocone type roof drain 5；On the one hand deflector can intercept miscellaneous
Matter prevents line clogging, on the other hand can be rectified with water conservancy diversion, greatly reduces air entrainment in water, makes the drainage pipeline in system be in
Existing flowing full state, using the potential energy of bridge floor height and standpipe 3 water outlet height difference, when rainwater flows in series through column pipe 2 and falls
Siphonage is formed, and generates peak suction at this, rainwater is discharged under the suction of negative pressure with higher speed in pipeline
Bridge floor.
Further, multiple deflectors are uniformly distributed circumferentially.
Further, column pipe 2 is horizontally disposed, and standpipe 3 is distributed vertically along bridge pier；Without any gradient, installation is facilitated to fix,
Nor affect on beauty.
Further, the column pipe 2 in traditional deck drainage system has certain gradient, but bridge bottom be it is flat, in this way
The gap between column pipe 2 and bridge bottom can be made increasing, both unsightly or be inconvenient to install fixation, and the siphon in this patent
Column pipe 2 in formula and drainage system facilitates installation, nor affects on beauty without any gradient.
Further, it receives and is equipped with immersible pump 8 in well 4；When liquid level reach a certain height, automatic turn on pump will receive well 4
In rainwater be discharged rapidly；The negative pressure in column pipe 2 can be increased in this way, the rainwater in system can be faster discharged.
Further, the drainability using the hydrocone type rain drainage system of immersible pump suction is stronger, drainability
Drainability depending on immersible pump 8 --- for the gravity stream deck drainage system of d=200mm, drainability 80L/
S, and the immersible pump for being 240L/s according to metered flow, drainability is Conventional gravity stream deck drainage system under same caliber
3.0 times.
The working principle of the invention:
The drainability of the hydrocone type rain drainage system of overpass is stronger, relative to Conventional gravity stream deck drainage system,
Drainability is its 1.5 times or more, can greatly reduce heavy rain flyover deck ponding situation.
Flow velocity in siphon pipe:
Wherein: v-velocity in pipes, m/s；
H-siphon pipe acting head, m；
ζ-siphon pipe coefficient of partial resistance；
λ-siphon pipe frictional resistant coefficient；
D-siphon bore, m；
L-siphon length of tube, m；
For the gravity stream deck drainage system of d=200mm, drainability is only related with caliber d, acts on siphon pipe
The coefficients such as head H, siphon pipe coefficient of partial resistance ζ, siphon pipe frictional resistant coefficient λ are unrelated, consult reference materials and learn as 80L/s；
And for the hydrocone type bridge floor rain drainage system of d=200mm, H=20 meters of siphon pipe acting head are taken, siphon pipe is total
Coefficient of partial resistance: ∑ ζ=1.2, siphon pipe frictional resistant coefficient λ=0.15, siphon pipe total length L=35 meter.
Its drainability, which is computed, learns that for 125L/s, drainability is gravity stream deck drainage system under same caliber
1.5 times or more.
Above is only presently preferred embodiments of the present invention, and of course, the scope of rights of the present invention cannot be limited by this,
Therefore according to equivalence changes made by scope of the present invention patent, still belong to protection scope of the present invention.
