Description
Technical field
Urban sewerage and drainage system is the pith of hydraulic engineering.The utility model is a kind of novel drainage system, can solve that current urban sewerage and drainage system occurs pour in down a chimney phenomenon, drainability is not enough, standard of drainage is low, poor reliability, the problem such as restive, by reasonable Arrangement, realize urban sewerage and drainage high standard, high reliability, be easy to the target controlled.
Background technology
Urban sewerage and drainage is that current water conservancy industry is paid close attention to more important topic.Urban sewerage and drainage system mainly comprises the parts such as building drainage pipe, ground and surface drainage pipe and city river.Drainage pipeline networks is in charge of and is built by municipal sector, and river course is mainly in charge of and is built by hydraulic department.City river is urban sewerage and drainage Cheng Guo district, his drainability direct relation city planting ductwork draining effect.City planting ductwork more complicated, influences each other larger, tends to occur that rainwater pours in down a chimney to low laying areas, forms waterlogging; Owing to adopting from row's pattern, no matter be city planting ductwork or the drainability in river course and the very difficult raising of standard.Because urban land is at full stretch, by widening, irrigation canals and ditches and river course improve drainability and standard is very difficult; Urban sewerage and drainage river course is river course with no pressure, and drainage pumping stations operated by rotary motion is at river outlet place.Urban ground is smooth, and river course is mild and long, and hydraulic slope is little, and draining acceleration capacity is low, and the Hydrodynamic time is long.Water pump is to drive river course to accelerate by reducing water surface curve, is that passive type drives, and because river course acceleration can be low, draining drives the response time long, even can cause water conservancy to interrupt, and there is no the driving effect of fine performance water pump; River course is mild and long, gradient is little, flow velocity is low, there is no enough scouring capabilities, very easily causes river course silting, affects draining reliability.
Be more than the subject matter of urban sewerage and drainage system, perplex the development that urban water conservancy is built always, must change the thinking of harnessing the river, crack the quagmire of current urban water conservancy.Therefore, the utility model is proposed.
Utility model content
The utility model provides a kind of new type drainage system, can solve preferably the not enough and existing problems of big and medium-sized cities draining hydraulic engineering.
Urban rainwater mainly contains building roofing, ground is discharged to municipal drainage pipe network, by main drainpipe, is pooled to city river, then is excreted to outer river.If outer river position increases to higher than Urban River Water position, river mouth, city sluice just need to be set and carry out dash, pumping plant is set simultaneously and carries out forced-ventilated.Because city river is mild and long, hydraulic slope is little, and draining acceleration capacity is low, and the Hydrodynamic time is long; Water pump is to drive by reducing water surface curve, is that passive type pulls, and draining drives the response time also very long, thereby easily causes low laying areas impeded drainage, and easily ponding, even can produce rainwater and pour in down a chimney.Therefore, urban sewerage and drainage system must strengthen its drainability and shorten the Hydrodynamic time, and prevents that rainwater from pouring in down a chimney.
In the link of urban sewerage and drainage system, most critical be main drainpipe and city river, because it adopts the form from row, bring many problems.
The utility model provides a kind of drainage system, it is characterized in that: by urban drainage pipe network, pressure injection node and by pressing drain header net to form, urban drainage pipe network is pooled to the pressure injection node in region separately by rainwater, adopt again pressure injection mode to enter and press drain header net, having the drain header of pressure net is the closed drain header of the pressure net that has, only river or inland river arrange drainage outlet outside, drain header net is not directly connected with urban drainage pipe network, pressure injection node is urban drainage pipe network and drain header net tie point, by collecting well, from row pipeline, forced-ventilated pipeline and maintenance gate valve form, wherein from row pipeline, comprise from comb mouth, from comb and non retern valve thereof, forced-ventilated pipeline comprises pump sump mouth, water pump, water inlet pipe and water outlet pipe, non retern valve, outlet valve, from row pipeline and forced-ventilated pipeline, can in parallelly access main comb net or access respectively main comb net.
In order to increase draining reliability, to be convenient to emergency repair, can in pressure injection node forced-ventilated pipeline, set up siamese connection, can increase drainability so at any time, improve draining reliability.
Regional urban sewerage and drainage system higher for physical features, that substantially can certainly arrange can adopt portable water pump and siamese connection is set in the forced-ventilated pipeline of pressure injection node, is prepared for urgent need.
The rainwater of urban drainage pipe network collects and passes through the pressure injection node in region separately, adopts pressure injection mode to enter and presses drain header net.When drainage distance is far away, can adopt multistage pressure injection node arranged in series, step by step pressuring method.
Basis is novel can also apply to urban sewage system.
(1) operating principle of drainage system
Urban drainage pipe network is pressure injection node with there being the tie point of pressure drain header net.The rainwater of urban drainage pipe network is pooled to the collecting well of pressure injection node, if the water level of collecting well, higher than the interior pressure head of drain header net,, by from row pipeline, directly injects drain header net by rainwater; If the water level of collecting well, lower than the interior pressure head of drain header net, is closed from the non retern valve of row pipeline and forced-ventilated pipeline automatically, until collecting well water level, reach while opening pump water level, starting mode of pump, by forced-ventilated pipeline, enters drain header net by rainwater pump drainage.
The diode of the suitable circuit of pressure injection node, its major function is the unidirectional water of crossing, it also has the water pump of utilization pressurization function simultaneously.At pressure injection node, arrange the siamese connection of some, can in case of emergency utilize the rainwater of mobile water pump or water pump vehicle pump drainage collecting well, to improve the reliability of drainage system.
Maintenance gate valve is when maintenance, for blocking and the contacting of drain header net.
Outlet valve is to prevent that vacuum and bubble from appearring in drain header net.
(2) design of drainage system
1. drain header net
Easy silting, rainwater are poured in down a chimney with the urban sewerage and drainage canal of drainability deficiency or river course remold as there being pressure drain header, be embedded in underground certain depth, guarantee that drain header maintains pressure condition.Drain header can be linked to be network according to actual needs, to increase draining scope, to improve drainability.
The diameter of drain header should be definite according to drain discharge and internal design pressure, and internal design pressure is related to drainability and pumps design lift, should be more definite by Technological Economy.
2. pressure injection node
Pressure injection node should be arranged on low laying areas, impeded drainage area, the particularly area that cannot meet drainage requirement from drainage channel with no pressure, and pressure injection node control scope is unsuitable excessive, preferably take small pumping station as main.Water pump scale is determined by existing draining standard.For improving draining reliability, be convenient to emergency processing rainwater and flood event, each pressure injection node can be laid the siamese connection of some, to utilize mobile suction pump to carry out interim pump drainage rainwater.The water pump that the pressure injection node that physical features is higher can only be established some engages, and is prepared for urgent need.
All the other design according to a conventional method.
