Description

A kind of underground pipe gallery drainage system based on existing blowdown canal
Technical field
A kind of Urban Underground pipe gallery drainage system is the utility model is related to, belongs to municipal drainage technical field, specifically For a kind of underground pipe gallery drainage system based on existing blowdown canal.
Background technology
In the process of Chinese high speed urbanization, urban size is increasing.The sewerage system built decades ago Have been over the service ability designed originally.On south China heavy rain multiple ground, urban waterlogging is urgently to be resolved hurrily.And with Economic rapid development municipal pollution is increasingly severe.Vehicle result in increasingly severe city surface source pollution with industrial expansion. And strong influence and traditional extensive work side can be produced to urban highway traffic in the transformation of old city drainage system Formula will produce substantial amounts of dust pollution air.
The content of the invention
The purpose of this utility model is that with regard to problem present in above-mentioned background technology, there is provided one kind is based on existing blowdown canal Underground pipe gallery drainage system.The utility model is not required to remove existing blowdown canal, but makes full use of existing draining energy Power, reduces workload, avoids the wasting of resources.
To solve the above-mentioned problems and realize above-mentioned requirements, the utility model takes following technical solution.
A kind of underground pipe gallery drainage system based on existing blowdown canal, it is characterised in that:Set on existing blowdown canal Stormwater overflow weir is put, guiding rainwater enters underground pipe gallery by overflow port, and underground pipe gallery is by cast-in-place underground pipe gallery base Plinth, cast-in-place ground lower header canal, cast-in-place underground pipe gallery road surface, prefabricated piping lane side wall and prefabricated underground pipe gallery dome are composed, in advance The first side wall grout hole and second sidewall grout hole, the first side wall grout hole and second sidewall grout hole are set on tubulation corridor side wall For the grouting connection between prefabricated piping lane side wall and soil, cast-in-place connecting sewing is used to connect prefabricated piping lane side wall and underground synthesis The cast-in-place partial component of piping lane, prefabricated underground pipe gallery dome by the first prefabricated underground pipe gallery dome, the second prefabricated underground pipe gallery dome, 3rd prefabricated underground pipe gallery dome is assembled, setting dome grout hole on prefabricated underground pipe gallery dome, in underground pipe gallery If wire casing, pipeline is to be laid with urban operating mechanism pipeline.
The existing blowdown canal top sets one of stormwater overflow weir at a certain distance, such as Fig. 5 discharge process schematic diagrames Shown, when rainfall is more than old canal design discharge, rainwater enters underground pipe gallery by stormwater overflow weir.
The first side wall grout hole and second sidewall grout hole are set on the prefabricated piping lane side wall, filled after the completion of assembly Slurry, fixes prefabricated piping lane side wall and plays waterproof.
Overflow port is set on the partial precast piping lane side wall, rainwater is flowed into underground pipe gallery.
The cast-in-place underground pipe gallery basis is located under prefabricated pipe corridor side wall, and the prefabricated components for bearing underground pipe gallery are prefabricated The dead weight of piping lane side wall and prefabricated underground pipe gallery dome and top soil pressure.
The cast-in-place ground lower header canal is located at side where overflow port.
The cast-in-place underground pipe gallery road surface sets 2% gradient to cast-in-place ground lower header canal direction.
The cast-in-place connecting sewing is used to connect fixed underground piping lane site concrete and prefabricated piping lane side wall.
The prefabricated underground pipe gallery dome is by three prefabricated components:First prefabricated underground pipe gallery dome, the second prefabricated underground Piping lane dome, the 3rd prefabricated underground pipe gallery dome are assembled, dome grout hole are set on prefabricated underground pipe gallery dome, in assembly Post-grouting is completed, prefabricated underground pipe gallery dome is fixed and plays waterproof.
It is observed that generally it is above usually concentration of wastewater, city in heavy rain initial stage (before rainfall 20 minutes) pollutant concentration Face source is the primary pollution source for causing water pollution, has the characteristics that high flow capacity, sudden and heavily contaminated.Such as Fig. 5 discharge processes Shown in schematic diagram, after the rainwater with larger flow velocity at heavy rain initial stage enters existing blowdown canal 1, its surface is washed away, takes away pollution Thing;When rainfall reaches old canal design discharge, rainwater cleaner at this time is then guided by stormwater overflow weir, enters ground by overflow port Lower pipe gallery, realizes the dirty shunting of rain, in order to the processing and utilization of later stage rainwater, and reduces urban waterlogging appearance Probability.
The cast-in-place underground pipe gallery of underground pipe gallery is basic, cast-in-place ground lower header canal, cast-in-place underground pipe gallery road surface is by existing Field formwork, pours and forms, have the advantages that good integrity, waterproof.
The prefabricated piping lane side wall of underground pipe gallery is in the milk after being installed in place by the first side wall grout hole and second sidewall Hole is in the milk, phenomena such as making prefabricated piping lane side wall and Zinc fractions tight bond, improve the globality of structure, prevent Groundwater infiltration Occur.Prefabricated piping lane side wall is connected by cast-in-place connecting sewing with the cast-in-place partial component of underground pipe gallery.
The prefabricated underground pipe gallery dome of underground pipe gallery is by three prefabricated components:First prefabricated underground pipe gallery dome, Two prefabricated underground pipe gallery domes, the 3rd prefabricated underground pipe gallery dome are assembled, are in the milk by dome grout hole, make prefabricated underground Piping lane dome is integrally formed.
The utility model has the following advantages:(1)For partial component by prefabrication, component quality is secure, eliminates The cumbersome formwork in construction site, maintenance, dismantles process, reduces construction pollution, have the advantages that high-quality, time saving, efficient, environmentally friendly. (2)Originally make full use of existing blowdown canal, reduce production cost, alleviate environmental pressure, preserve the ecological environment, realize Green Development and Production.(3)This drainage system realizes the dirty shunting of rain, and city surface source pollution is improved, is had in reconstruction of the old city town greatly Play space.
