Description
Technical field
It is a kind of to be suitable for reducing the device that rainwater inspection well crosses water local resistance.
Background technology
In recent years, quickly propelling with Urbanization in China, City Terrain landforms change larger, Severe rainstorm weather
Occurrence frequency is also increasing, and urban waterlogging disaster often occurs.When more serious effectiveness factors occur, row can be seriously affected
Vehicle is safe and will also result in threat to the life security of resident, often causes larger economic loss and safety accident.It is main
Reason is wanted to be that the traditional Water drainage system design standard in China is relatively low.
Connection is complicated various between Storm Sewer Network road, and each length of pipe section, size are different.Straight-through check well is urban rainwater
One of highly important composition in system, due to complexity of topography and geomorphology etc., arrangement spacing is between 30~70m, quantity
It is huge.But the local resistance loss at inspection shaft is not considered when the design of China's storm sewer system, this will over-evaluate pipeline
Practical conveyance capacity makes pipe network system drainage waterlogging prevention ability be not achieved and should require.In the feelings for encountering the extreme weathers such as heavy showers
Under condition, the practical local resistance of existing gully is larger so that drainage effect is bad, easily because draining is not in time to draw
Waterlogging is sent out, and then influences the normally travel of vehicle and threatens the life security of resident, causes great security risk.About solution
It is certainly drained not in time caused by inspection shaft local resistance loss, has many methods that can carry out.For example, can be existing according to that can meet
Entire drainage system is redesigned in the standard of dewatering needs, but the method needs original drainage system carrying out large area more
It changes, economic cost is excessively high, implements have prodigious difficulty.
It is found that at present about urban waterlogging is coped with, the inspection shaft local resistance research in drainage system is one important
Research direction, the drainability of drainage system can effectively be enhanced by reducing the local resistance of inspection shaft, to be urban waterlogging
Problem provides a kind of feasible mitigation strategy.
In current technology, lack a kind of easy for installation, the lower rainwater inspection well abatement local resistance of economic cost
Device.

Beneficial effects of the present invention：
The present invention can carry out upgrading on existing drainage system to inspection shaft.To mitigate in former drainage system, rainwater
By the problem of storm-water system drainability declines caused by the local resistance of formation when inspection shaft.When upstream rain pipe flows into
When inspection shaft, rainwater is influenced by the whole beam flow passage device of rainwater, and the flowing of rainwater is still flowed substantially according to former runner
Into next section of rain pipe.To compare original system, local resistance of the rainwater by inspection shaft when is reduced, improves draining system
The drainability of system.Meanwhile gas vent is set to facilitate the exhaust in rainwater flow process, mitigate in storm sewer because of balloon-shaped
At and cause pipeline water delivery resistance increase the problem of.And it is provided with inlet opening, ensure the water energy of the inlet for stom water of inspection shaft connection
Entered in drainage system by inspection shaft, ensure that the function of inspection shaft is unaffected, and water is entered by inlet opening and is
When system, the larger suspending sundries in rainwater can be intercepted and be collected by effective, mitigate drainage system blockage problem and the dirt that suspends
Dye object assembles the pollution problem of laggard lake inlet through storm-water system.
Specifically：
1, the present invention effectively can carry out line to the flowing of rainwater so that rainwater will not be sent out during flowing through inspection shaft
It dissipates, enters back into downstream storm sewer, reduce this local resistance that rainwater passes through inspection shaft in the process.
2, the gas vent that apparatus of the present invention pass through setting so that the gas discharge carried in rainwater flow process reduces rain
Resistance of the water in drainage system in flow process.
3, present invention setting inlet opening so that the water in the inlet for stom water of inspection shaft connection can smoothly enter into drainage system,
To not influence the normal use of inspection shaft.
4, when the inlet for stom water water of inspection shaft connection, when by the inlet opening of the present apparatus, can by larger suspended matter into
Row, which intercepts, to be collected, and is caused after drainage system assembles laggard lake inlet with pollutant to mitigate the problem of drainage system blocks
Pollution problem.
5, the whole beam flow passage device of rainwater of the invention can be mounted directly on existing inspection shaft, and economic cost is relatively low,
Simple to install.
6, apparatus of the present invention do not need external energy during playing a role, and cost is relatively low.
7, the device of the invention can well adapt to the limited engineering demand of execution conditions.

Specific implementation mode
It is as shown in Figure 1 it is a kind of crossing schematic diagram of the device of water local resistance inspection shaft suitable for reducing inspection shaft,
Including the whole beam flow passage device 1 of rainwater, when entering inspection shaft 2 for the water to the preceding paragraph rain pipe 3, rainwater runner is carried out about
Beam so that former runner state can be kept to enter in downstream rain pipe 4 as far as possible when rainwater passes through inspection shaft, to reduce rainwater
Pass through local resistance when inspection shaft.The inlet for stom water 5 of inspection shaft connection transfers after rainwater-collecting pipeline 6 by rainwater and enters
In inspection shaft, then enter next section of rain pipe after merging with the water of upstream rain pipe.As shown in figure 3, upstream rain pipe comes
The runner that water can effectively constrain rainwater by the whole beam flow passage device of rainwater is being arranged to can smoothly enter into the rain pipe of downstream
It is flowed in water system.As seen in Figure 4, the rainwater fluidised form being fitted without in the inspection shaft of apparatus of the present invention, the preceding paragraph rain pipe
Four diffusings of meeting are dynamic after water enters inspection shaft, then collect into next section of rain pipe, which polymerize again by diverging,
Larger local resistance can be formed, the energy of rainwater flowing can be influenced, reduce the drainability of drainage system.Pass through Fig. 3 and Fig. 4
