Description
Technical field
The present invention relates to municipal drainage pipelines to conserve clear and coherent equipment field more particularly to a kind of drainage pipeline dredging dredging dress
It sets.
Background technology
Important component of the drainage pipeline as municipal works, undertake urban life and trade effluent, rainwater collection,
The effect of transmission.Rubbish incidental in drainage pipeline can be such that effluent flow rate in pipeline reduces, and retain grease and floating material, to
Reduce the conveying capacity of pipeline so that drainage pipeline generates siltation, results in blockage.The sewerage system of developed country is adopted mostly
With big-diameter pipeline or super big-diameter pipeline, and rain sewage diversion pipe-line system is used, this makes external many dredging dredgings fill
The standby pipeline that cannot be used for pipe with small pipe diameter in the country adds the row of stealing and steals to fall to wait rows in addition, domestic drainage pipeline carries out confluence of rainwater and sewage
For inner wall of the pipe tamper is presented diversification, complicates feature.
The dredging dredging equipment and method used in China's drainage pipeline networks at present mainly has：Winch dredging method；Waterpower is rushed
Wash method；It is artificial to remove method；High-pressure water jet dredging method.(1) winch dredging method：This method is China's pipeline most widely used at present
Dredging method is connected between winch by hawser, and have barrier on hawser by checking that two winches are arranged in well head at two
Object, pulling hawser makes barrier moves back and forth in the duct to take tamper out of, and gathers inspection well head by rubbish is blocked, and leads to
It crosses lifting barrel mode or silt pumping car mode and concentrates cleaning tamper from inspection shaft, but this method needs artificial underground to wear
Rope, underground work bad environments are very easy to cause safety accident.(2) hydrodynamic cleaning method：This method requires in drainage pipeline
Mud should not be excessive, using the water of larger flow by bottleneck area, is directly rinsed to tamper, but this method is easy to make
New siltation is formed at upstream drainage pipeline to block.(3) method is manually removed：Staff's hand inside pipeline by handheld tool
Work is dredged, and this method can clear up some and block serious pipeline, but the narrow space of pipeline, dredging personnel curl in pipeline
Inside can not efficiently be dredged, and the labor intensity of staff is big, and it is hidden to exist simultaneously prodigious safety for high labor cost
Suffer from.(4) high-pressure water jet dredging method：This method drives high-pressure hydraulic pump by dedicated water car engine, and the water in waterwheel is added
Pressure, is then depressed at nozzle, forms one direction reaction thrust by nozzle jetting, nozzle and sebific duct is pushed to go in the duct
Into washing away inner wall of the pipe while advancing, high-pressure water jet dredging method is applicable in multiple diameter pipeline, but this kind of method can only be used
In the not serious drainage pipeline of blocking, while dredging less efficient.
With the continuous expansion of city size, the blocking siltation problem of drainage pipeline is on the rise.Due to state's internal drainage pipe
Blocking rubbish diversification in road, such as garbage, the building waste of unit in charge of construction, concrete block etc., exacerbate drainpipe
The blockage in road, drainage pipeline inner wall have thicker hardened hard scale, winch dredging method, hydrodynamic cleaning method, high-pressure water jet
Dredging method all can not effectively dredge dredging, can only rely on artificial progress down-hole pipe dredging or be dismantled to pipeline, if
It will be a large-engineering directly to excavate and replace these blocking pipelines, need multidisciplinary cooperation, and long construction period, expense
Higher seriously affects the normal operation of traffic.
