Description
Technical field
The utility model relates to the method for city waterlogging control and water pollution control, particularly relates to a kind of equipment that can improve prevention waterlogging standard, can effectively control again water pollution.
Background technology
Along with the expansion in city and the increasing of construction density, hardened ground rate is more and more high, original reservoir, massif, lake, fish pond are occupied gradually, it is more and more narrow that section is gushed in river, earth's surface water storage, draining and the natural purifying ability in city weaken greatly, add that urban heat land effect causes extreme weather to take place frequently, townsfolk's the security of the lives and property in city water logging and waterlogging serious threat, and waterlogging problem has become a urban water difficult problem.
The high population density and urban construction density strengthen rapidly city surface source pollution load, between flush period, surface flow just rain pollute and the pollution load of overflow (CSO) in combined system area day by day serious, be one of important sources of urban water-body pollution.
The standard of widening river course, building large-scale discharge conduit and can improve Urban Waterlogging, newly-increased build city just rain and combined sewage storage pond be effective water pollution control method, but all can relate to a large amount of housing demolitions and underground utilities migration, invest huge.The complexity of building dense and underground utilities is crowded to be made to improve urban sewerage and drainage standard and improve and cut a dirty system and become abnormal difficult by building shallow-layer subsoil drain.
Utility model content
Main purpose of the present utility model is to provide and a kind ofly not only can have improved city prevention waterlogging standard but also can effectively control the equipment that water pollutes, it can overcome the shortcoming that needs a large amount of housing demolitions in existing Drainage System Construction on the one hand, overcomes on the other hand the shortcoming of existing drainage function singleness.
The utility model object is achieved through the following technical solutions:
A kind of equipment that improves city prevention waterlogging standard and control water pollution, comprise and set up city deep layer tunnel system, deep layer tunnel system comprises main body tunnel, connect vertical shaft and drainage pumping plant, drainage pumping plant is provided with drain pump group and the pump group of drainning off floodwaters, main body tunnel is horizontally placed on urban ground 30m at least below, multiple connection vertical shafts are distributed in main body tunnel upper, the lower end that connects vertical shaft is connected logical with main body tunnel, the upper end that connects vertical shaft is connected with city shallow-layer wastewater interception pipe by control valve, drainage pumping plant is located at by nearly main body tunnel and city underwater and urban sewage water channel, drain pump group is communicated with main body tunnel by pipeline with urban sewage water channel, the pump group of drainning off floodwaters is communicated with main body tunnel by pipeline with city underwater.
Concrete operation method of the present utility model is as follows:
At amount of precipitation hour, open and connect vertical shaft control valve, the combined sewage that exceedes shallow-layer wastewater interception pipe ability enters main body tunnel by connection vertical shaft and regulates and stores, open after the rain drain pump group, the combined sewage in the main body tunnel of regulating and storing is transported to downstream Wastewater Treatment Plant by city underwater and processes.
At amount of precipitation greatly when having exceeded the water drainage standard of basin main stem, open simultaneously and connect vertical shaft control valve and the pump group of drainning off floodwaters, flood enters main body tunnel and is discharged to underwater by the pump group of drainning off floodwaters by connecting vertical shaft from shallow-layer wastewater interception pipe, and main body tunnel is as flood diversion passage.
Compared with prior art, the utlity model has substantive distinguishing features and progress:
Underground deep layer tunnel is used for drainage works by the utility model, on the one hand, utilize the Variation Features of amount of precipitation size, and by the management and running to deep layer tunnel, make tunnel drain off floodwaters and improve prevention waterlogging standard as flood diversion passage when amount of precipitation is large, when amount of precipitation is little, as combined sewage storage pond, controls water and pollute, make a tunnel facility utilize the time difference of rainfall to distribute and have two kinds of functions concurrently, avoided overlapping investment.On the other hand, by outlet tunnel construction, in underground deep layer space, except connecting vertical shaft, to occupy less use extraterrestrial, there is no other ground installations, avoided housing demolition.In basin, existing shallow-layer river course drains off floodwaters too lately, and while there is waterlogging risk, the utility model is using tunnel as the flood diversion passage in basin, effectively prevents that waterlogging from occurring, and can effectively improve the prevention waterlogging standard in basin.
