Abstract
The invention discloses a method for replacing a sewage pipeline, which does not disturb residents or destroy foundation of surrounding buildings, does not influence traffic, hardly pollutes the environment and has low construction cost. The method comprises the following steps: (1) dividing a sewage pipeline into a plurality of construction sections according to diameter differences and break points of the sewage pipeline; (2) forming a first work pit and a second work pit at two ends of each construction section; (3) putting a new pipeline in the first work pit; (4) assembling tube drawing bench equipment in the second work pit; (5) inserting tools for crushing and expanding pipelines into an old pipeline from the second work pit to crush the old pipeline; and (6) drawing a new pipeline to the position of the old pipeline by the tube drawing bench equipment.
Description
Technical field
The invention belongs to the technical field of construction work, relate to a kind of method of changing sewage conduct particularly.
Background technology
Domestic many underground sewers wear out and seepage with age at present, are badly in need of the sewage conduct that more renews.But, because generally there are a lot of residential quarters, commercial facility, traffic route etc. in the ground at underground sewer place, if whole excavation will have a strong impact on the people's life, destroy surrounding building basis and underground utilities, disturb traffic, contaminated environment, construction cost is huge.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, provide a kind of and do not disturb residents, do not destroy surrounding building basis and underground utilities, do not disturb traffic, the method for of low pollution environment, replacing sewage conduct that construction cost is cheap.
Technical solution of the present invention is: the method for this replacing sewage conduct may further comprise the steps:
(1) diameter difference and the break according to sewage conduct is divided into some construction sections;
(2) at the two ends of each construction section first working pit, second working pit are set respectively;
(3) in first working pit, put into new pipeline;
(4) bench equipment is installed in second working pit;
(5) instrument with broken and expand tube inserts in the old pipeline from second working pit, carries out the fragmentation of old pipeline;
(6) utilize bench equipment new pipeline to be drawn in the position of old pipeline.
Because this method is only to dig two holes, directly more renew pipeline in the position of old pipeline, so do not disturb residents, do not destroy surrounding building basis and underground utilities, do not disturb traffic, of low pollution environment, construction cost be cheap.
The specific embodiment
Below technical scheme of the present invention is described in further detail.
The method of this replacing sewage conduct may further comprise the steps:
(1) diameter difference and the break according to sewage conduct is divided into some construction sections;
(2) at the two ends of each construction section first working pit, second working pit are set respectively;
(3) in first working pit, put into new pipeline;
(4) bench equipment is installed in second working pit;
(5) instrument with broken and expand tube inserts in the old pipeline from second working pit, carries out the fragmentation of old pipeline;
(6) utilize bench equipment new pipeline to be drawn in the position of old pipeline.The expand tube tool that is about to a cone inserts and is guide in the old pipeline, makes old pipeline breaking by pulling force, and broken pipeline fragment is squeezed on every side in the soil, adopts bench equipment that new pipeline is drawn in old pipeline location, finishes the replacing construction of sewage conduct.
The setting that it is noted that working pit should be avoided road and commercial doorway, makes things convenient for resident trip; With caliber is one section; What pipeline had a break divides one section in addition, changes pulling force when excessive, the mouth of pipe may occur and stagger, and repaiies and changes after straight again.
Preferably, step (3) also comprises the port of new pipeline planished, heats, holds presses cooling, and fusion one under the automatic pressurization of hydraulic pressure then is again with new pipe joint sweat soldering.
Preferably, make the diameter of expand tube head of instrument of broken and expand tube greater than the diameter of old pipeline in the step (5).Purpose is that enough environment spaces are provided when changing pipeline, reduces the new pipeline replaced and the frictional force between the stratum.
Preferably, new pipeline adopts hdpe pipe.Be PE tubing, characteristics are that corrosion-resistant, high temperature resistant, non-scaling, life-span are long.
Employing this method construction has solved eighties sewage conduct because of the aging leakage problems of pipeline, during the maintain and replace underground utilities, and " belly breaking " construction again.This method, it is little to have the construction operation face, digging-free, short construction period, integrated cost is low, many advantages such as is widely used, can reduce to greatest extent to the interference of traffic with to the pollution of environment, reduced the sorrow people that construction brings, reduced, reduced construction cost surrounding building basis and the crisscross destruction of underground utilities.To the protection fee and the removal expense of underground utilities, abolish old pipe and more renew pipe and once finish when having reduced excavation simultaneously, the duration is short, and integrated cost is low.
The above; it only is preferred embodiment of the present invention; be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs to the protection domain of technical solution of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
