Description

A kind of anti-siltation pipeline

Technical field

The utility model belongs to municipal drainage pipeline technical field, more particularly to a kind of anti-siltation pipeline.

Background technology

With economic development and the continuous expansion of city size, the scale of urban discharging pipeline is increasing, drainage pipeline Siltation problem be on the rise, all there is different degrees of siltation problem in the drainage pipeline in lot of domestic and foreign city at present.

The siltation problem of drainage pipeline is mostly caused by the silt in pipe-line system and suspended solids deposit. After the big branch drain of the gradient flows into soft arterial drainage, flow velocity reduces sewage in drainage pipeline, is taken in sewage The silt and suspended solids of band are easy to deposit in the main pipe that the gradient is small, caliber is big, so as to which drainage pipeline be caused to become silted up Product.For drainage system pipeline, design discharge is designed according to the flow of rainy season confluence of rainwater and sewage.Pipeline connects in dry season Receive sewage in the flow and pipeline of sewage flow velocity much smaller than rainy season value, this smoothly be taken away by sewage in rainy season big Particle suspensions are deposited at dry season, and then drainage pipeline is caused to deposit.Sediment such as stone, brick in drainage pipeline Block, polybag, branch etc. can be such that effluent flow rate in pipeline reduces, and retain grease and floating material, so as to reduce the conveying of pipeline Ability aggravates the siltation of drainage pipeline.When the sediment in drainage pipeline reaches a certain level, the conveying capacity of pipeline can be anxious Play declines, and the speed of sediment siltation is also gradually accelerated, and ultimately causes pipeline and blocks.

Less, the existing research for pipe dredging problem is studied in dredging for drainage pipeline accordingly both at home and abroad Also it is only limitted to the various measures taken later of pipeline siltation occurring.Therefore the solution for the problem of depositing for pipeline inside dirt It is particularly important.

Utility model content

In order to solve above-mentioned technical problem, the utility model provides a kind of anti-siltation pipeline, can solve to prevent Dirt siltation problem inside pipeline makes dirt be just blocked before pipeline siltation is formed using the detachable trash rack column of multilayer Come, efficiently separate dirt, sludge and sewage, form defence type pipe dredging system, make pipe dredging work more quick, simple It is single, convenient, and effectively prevent dirt reverse osmosis enter pipeline periphery soil layer and reduce pipeline infiltration, corrosion incidence, repair and It safeguards more convenient.

The technical solution adopted in the utility model is as follows：

A kind of anti-siltation pipeline inside sets the detachable trash rack column (3) in large aperture first, and certain distance setting thereafter is small The detachable trash rack column (4) in aperture, binds respectively with duct wall (1)；The detachable trash rack column (3) in large aperture and small-bore On the left of detachable trash rack column (4), buffer table (6) and french drain (5) are set respectively successively from the distant to the near；French drain (5) is including coarse sand Layer（5-1）, rock layers fine crushing（5-2）, coarse crushing rock layers（5-3）, dirt collection branch pipe (5-4) and geotextiles loaded filter (5-5)；It is pasting respectively French drain (5) is excavated in the left side on nearly detachable trash rack column, builds draining shaft (7) by laying bricks or stones inside french drain (5) so that draining shaft (7) well head position is arranged in sewage conduct, draining shaft (7) shaft bottom position connection dirt collection branch pipe (5-4)；Geotextiles loaded filter (5-5) is arranged on french drain（5）Peripheral surface, by french drain（5）It wraps up.

Further, the duct wall (1) is preferentially using water-proof concrete, and add impervious barrier in ectonexine.

Further, the impervious barrier (2) preferentially using cement mortar waterproof layer, coil waterproof layer, coating waterproof layer, It is one or more in drainage systems waterproof layer and bentonite waterproof material waterproofing layer, when using single waterproof layer, preferentially Using two layers and above waterproof type.

Further, the detachable trash rack column in the large aperture（3）For detachable member, the larger dirt of volume can be intercepted Object preferentially using stainless steel material, is bound by stainless steel rebar, surface spraying anticorrosion glass flake plasticine and coating.

Further, the detachable trash rack column in the small-bore（4）For detachable member, the dirt of small volume can be intercepted Object preferentially using stainless steel material, is bound by stainless steel rebar, surface spraying anticorrosion glass flake plasticine and coating.

Further, the dirt collection branch pipe (5-4) is using flexible porous tube, model FH200, in dirt collection branch pipe (5- 4) it is internal that dredging robot or mobile mud concentration is allowed to dispel device and pass through, make sewage conduct, draining shaft（7）, dirt collection Branch pipe（5-4）Three parts structure forms dirt collection, the anti-siltation system of decontamination.

Further, the geotextiles loaded filter (5-5) is nominal to be broken using filament spunbond needling non-woven geotextiles 15 k N/m of intensity.

Further, the coarse sands layer（5-1）Preferential arrangement thickness 50-100cm, grain size 3-4mm.

Further, the rock layers fine crushing（5-2）Preferential arrangement thickness 0-25cm, grain size 0.5-2cm.

Further, the coarse crushing rock layers（5-3）Preferential arrangement thickness 20-50cm, grain size 4-6cm.

Further, the buffer table (6) is preferentially 45 ° of slope using the angle of gradient, preferentially using anti-water coagulation Soil is built by laying bricks or stones.

Further, the detachable trash rack in multilayer difference size aperture can be installed in the pipeline according to actual conditions Column.

The beneficial effects of the utility model：

The beneficial effects of the utility model are to become passive type dredging as initiative defense, and flow is slowed down by buffer table, no Multilayer trash rack column with aperture can efficiently separate dirt, sludge and sewage, forms dirt collection, the anti-siltation system of decontamination, makes Pipe dredging work is quicker, simple, convenient, and dirt reverse osmosis is effectively prevent to enter pipeline periphery soil layer and reduce pipeline and is oozed Water, the incidence of corrosion, R and M are more convenient.
