Technical field
This utility model relates to a kind of municipal drainage pipe network overflow and controls equipment, particularly relates to a kind of municipal drainage pipe network automatic scalable buoyancy tank weir.
Background technology
In recent years, urban waterlogging phenomenon is commonplace in the whole nation, occurs in that the awkward situation of city " seeing sea " again and again.It is all caused by waterlogging that city is flooded, and climate change causes urban storm to take place frequently, and interior a large amount of rainfalls, cause municipal drainage system to paralyse in short-term；Increase with the runoff coefficient of magnitude heavy rain, increase the runoff of urban area；Pipe network planning and designing standard is on the low side, and Drainage System Construction is delayed, lacks long-range systematicness planning etc..
Old town carries out rain dirt shunting transformation and faces many restrictions, not only expend substantial contribution and time, retrofit work is difficult, the most leading transformation is not the most thorough, poor effect, and some cities are through practical exploration for many years, the most gradually the thinking generation to thoroughly " conjunction change point " is doubted, and start remedies, and to attempt taking control measure to pollute to reduce combined system on the basis of original combined flow system, it is a kind of measure reducing urban waterlogging that overflow controls.
It is that the water lev el control body of wall by common gate or certain altitude is controlled that overflow in general sense controls.(1). common gate controls to be the water level according to setting, and by electronic or open manually, excretes the water yield beyond water level.(2). using the overflow body of wall of certain elevation, when water level is increased beyond wall inclination height, automatic overflow is discharged by water.(3). another conventional outflow mode is design Vatch basin, designing the drain pipe of differing heights in Vatch basin, under normal circumstances, water body flows to downstream wastewater treatment plant, Vatch basin middle water level rises when raining heavyly, and part water body overflows to receive water body from the drain pipe of eminence.
Purely mechanic gate in the market, its operation principle is all the opened by pressure gate utilizing water body to produce, the unlatching which results in use gate is easily subject to the impact of the level of tail water, open too early as do not arrived flood discharge water level, or exceed flood discharge water level to open too late, it is impossible to ensure that the flood level in design is precisely opened.
Overflow body of wall and Vatch basin, although be not required to extra driving force and carry out overflow, but in any case, overflow position is changeless, and when the water level of accepted downstream water body is higher, on the one hand jacking can not overflow, it is also possible to produce backflow phenomenon；And overflow wall in general sense, in the case of equal spillway discharge, needs bigger structure floor space and Geng Gao overflow body of wall, adds construction cost.
