Description
Technical field
A kind of jetting type draining four-way inspection shaft is the utility model is related to, belongs to drainage system field, more particularly to reduces
The drainage inspection well of water turbulence.
Background technology
City rainwater drainage is typically all functional in organized water drainage, and the rainwater on ground drains into storm sewer by runoff gathering, then
Natural water is discharged into by Stormwater Drainage System.Most of urban rainwater pipeline system is laid along under road, and urban road is indulged
Traversed by is pitched, and the unit of both sides of the road or the rainwater access urban rainwater pipeline of residential area, are accessed by four-way inspection shaft.
When carrying out urban rainwater pipeline design, designer is typically all to apply mechanically standard drawing.Existing national standard drawing《06MS201 cities
Political affairs drainage pipeline project and affiliated facility》Four-way inspection shaft, branch diameter and supervisor caliber it is smaller when use circular inspection well,
Branch pipe is accessed to current with downstream supervisor using 90 °~135 ° of access downstream, the reduction of pipe with small pipe diameter drainage inspection well flow, branch pipe
Influence it is little.When being responsible for 900~2000mm of caliber, rectangle four-way inspection shaft should be used, rectangle four-way inspection in standard drawing
Well stream groove very little, rainwater inspection well chute are highly only the half of caliber, and branch pipe and upstream supervisor connect in 90 °, branch pipe with it is upper
Substantially no chute blocks between play pipe road, current and the upstream opposite jet flow of branch pipe, very strong turbulent flow is formed, even if downstream master
Pipe is according to upstream supervisor and branch pipe flow design, and because local head loss is larger, importing the water of inspection shaft can not effectively arrange
Downstream pipeline, when especially the branch pipe gradient is larger, branch pipe flow rate of water flow is larger, and turbulent flow phenomenon is even more serious, therefore, in reality
In engineering often there is four-way inspection shaft draining and do not occur waterlogging suddenly in heavy rain or rainstorm weather, and flowing full does not show downstream line
As.
Patent No. CN201410275893.0 utility model patent《Prevent the draining four-way inspection shaft of opposite jet flow》, adopt
With the radius of turn of increase branch pipe chute, set isolation platform to prevent opposite jet flow, reduce branch pipe current and the current of upstream supervisor
It the angle of cut, can effectively reduce the local head loss of four-way inspection shaft, improve the discharge capacity of inspection shaft.But upstream current with
Two side branch current are in 15~30 ° of the angle of cut, and three strands of current, which converge, still can produce certain turbulent flow, and influence inspection shaft crosses water
Ability.
Existing four-way drainage inspection well is all to use brick or concreting chute, and curved surface chute being built by laying bricks or stones and smearing
Face, complex process, difficulty of construction is big, and quality is difficult to ensure that, the curve form of chute and the roughness on surface all directly affect inspection
Look into the displacement of well.
The content of the invention
The purpose of this utility model is：A kind of jetting type draining four-way inspection shaft is provided, mainly by charge for remittance device, well body, work
Make platform composition, charge for remittance device is to cross water component using what high molecule plastic material was molded into being molded, by upstream supervisor and two side branch streams
Groove separates independently of each other, and current do not liquidate mutually before a flow direction is accumulated in well and turbulent flow, three strands of current are complete
Collect after flowing to same direction, substantially reduce the loss of flood peak.Beneficial effect is：Charge for remittance device adopt it is made of plastic, chute
Special tectonic and smooth surface can ensure good hydraulics, and frosting is smooth, and roughness greatly reduces, and reduce disorderly
Flow phenomenon, so as to improve the flow of four-way inspection shaft.Plastics charge for remittance device and brick, concrete combine, chute easy construction and energy
Ensure quality, brick mix structure can ensure the intensity of inspection shaft.
