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.
