Description

The active curb formula of the segregation system of management and use urban rainwater pipe drainage system

Affiliated field

The active curb formula of segregation system pipe drainage system is a kind of system that urban rainwater is carried out management and use.The design of system is to utilize urban road; Use hollow type curb laying road curb, form pipeline with this, and with the sensible formation pipe network of road; In conjunction with catchment facility and the pumping plant that are arranged on low-lying location or select location; Urban rainwater is carried out management and use, transform old-fashioned draining system, realize segregation system discharging that municipal sewage separates with precipitation and the prevention and control of city waterlogging.

Background technology

Urban sewerage and drainage according to source and character, is divided into municipal sewage and precipitation.Municipal sewage is meant the sanitary sewage that enters urban discharging pipeline and the summation of production waste.Sanitary sewage and production waste all contain a large amount of pollutants, must be used for irrigated farmland or utilization again through just entering natural water after the strict processing.Precipitation is meant Atmospheric precipitation, comprises liquid precipitation and solid precipitation.Atmospheric precipitation just need not handled usually can directly enter natural water, is used for irrigated farmland or utilization again.In China city, existing draining system mainly is the shutoff type combined drainage system.Also have many mature cities even be still the direct-discharging combined drainage system.So-called combined system is meant municipal wastewater and precipitation is included in the sewer simultaneously, forms the combined sewage discharging.The method of combined system has not only increased the burden of water treatment, and causes the water resource waste that can directly utilize in a large number.And single flow is without any processing, directly enters natural water nearby, and this mode can make to be received water body and suffer severe contamination.Shutoff type is before entering natural water, increases a water treatment link, enters natural water after treatment.When amount of precipitation increases, after the combined sewage flow exceeds disposal ability, have part and overflow and directly enter natural water, pollute and receive water body.The shutoff type combined drainage system is commonly used now, also is domestic old urban renewal drainage system method commonly used.Separated drainage system is with municipal sewage and rainwater, respectively at two or more drainage systems of independently getting rid of in the pipe duct separately.The system of draining-off sewage is called foul water system, and the system of getting rid of rainwater is called storm-water system.Sewage drains into treatment plant and handles the back discharging, and rainwater enters natural water nearby.The benefit of this mode is can not form combined sewage, and the sewage emissions amount is relatively stable, measurable, can plan, controllability is strong, helps the appropriate design sewage treatment capacity, control is to the pollution of natural water.Separated drainage system is the developing direction of urban sewerage and drainage system.No matter and any system all has only row's function.Many cities of China, because historical reasons, the foundation drainage pipe network all is a combined system, since the fast development in city, the ability wretched insufficiency of old drainage pipeline networks, and during precipitation, discharge capacity just can't be satisfied the demand, and often causes waterlogging.Transform combined system discharging system, the development separated drainage system is the important content of present urban development and transformation.But the underground various pipe networks in city are complicated, and the underground space is very limited, can not hold a storm-water drainage pipe duct again.And a subsurface stormwater discharge pipe line is built in construction, be not a road open the broken tripe of intestines, but entire city open the broken tripe of intestines, the complicacy of technology, the difficulty of construction, and all be unacceptable to townie influence.This has become the bottleneck of urban development and reconstruction of the old city town.

Summary of the invention:

To the deficiency of existing drainage pattern, the present invention program utilizes existing urban road, and road edge is designed to pipeline; Build up the surface drainage pipe; Along with the sensible formation pipe network of road, and combine to be arranged on the collected water storage facility and the fixed pump station of low-lying location or select location, realize management and use urban rainwater; Change city combined system draining form, solve the problem of city waterlogging and water resource waste.

Technical scheme of the present invention is: in the middle of using is the hollow type curb of pipeline, forms two flowing lines on both sides of the road in the road, and along with the extension of road connects the formation drainage pipeline networks.According to landform and actual needs, in the low-lying location of road or selected region set up the collected water storage system that forms by collecting-tank, sedimentation basin, infiltration pond, reservoir and fixed pump station, the bottom laying permeable layer in infiltration pond, pumping plant links to each other with curb formula pipeline.So just, form initiatively vent type storm water management system of a segregation system.

The invention has the beneficial effects as follows: curb formula pipe drainage system, technical requirements is low, and cost of production is little, and is easily manufactured.This curb formula pipe drainage system need not take the underground space, therefore can the various pipes of underground complicacy do not damaged and influence, and easy construction, maintenance and changing easily, daily management and maintenance cost are low.Curb formula pipe drainage system can adapt to various types of urban plannings, because curb formula pipeline is along with road is walked, the local curb formula pipeline of path just can be led to, and need not scruple subsurface picture, does not also have obstacle on the ground.Because be the power discharging, can be provided with flexibly, according to the environmental quality and the draining intention of landform and downstream area, design curb formula pipeline rout is set up the relay pumping plant, the networking in flakes of formation scale, transfer in the formation zone, drainability.Extraordinary autgmentability is arranged, can be along with development of city, the extension of road, constantly expansion realizes the transformation of Urban Old draining system and perfect.Be easy to carry out standardization.Can combine the engineering of controlling flood and draining flooded fields easily, realize prevention and control the city waterlogging.Curb formula pipeline is connected the collecting-tank, sedimentation basin, infiltration pond, reservoir, station pump of low-lying region or the underground foundation of select location etc., forms combining of line and point, reaches the function of water conservancy projects, and rainfall resource is carried out management and use.Can realize oozing, hold, use, transfer, arranging five functional.Ooze, promptly to underground infiltration, replenish underground water.Hold, promptly when amount of precipitation is suitable, store certain water yield.With, promptly utilize the water yield store to supply municipal administration, gardens, environmental sanitation, fire-fighting, view (like fountain pool, wetland etc.), and part commercial water (like carwash etc.) use.Transfer, be that amount of precipitation is unbalanced or when demand is arranged, water transfer in certain zone.Row, promptly when super large precipitation, rainfall is directly entered natural water.Owing to be connected with station pump, have initiatively discharge capacity, can carry out the pumping plant relay, long distance discharging.
