Description
Technical field
The invention belongs to the technical fields of architectural engineering, more particularly to a kind of method of efficiently replacement sewage conduct.
Background technique
Many underground sewers domestic at present with age aging and leak, be badly in need of the sewage conduct more renewed.But by
Generally there are many residential areas, commercial facility, traffic route etc. in the ground where underground sewer, it will if all excavated
The life of the people can be seriously affected, surrounding building basis and underground utilities is destroyed, interferes traffic, pollute environment, construction cost
It is huge.
Summary of the invention
Technology of the invention solves the problems, such as: overcoming that existing replacement sewage conduct engineering amount is big, noise is big, environment is broken
The disadvantages of bad serious and at high cost, provides method that is a kind of novel and having the advantages that a variety of replacement sewage conducts, this method work
Journey amount is small, noise is low, does not influence peripheral facilities and the masses life and work, and engineering cost few to environmental disruption are low.
The technical solution of the invention is as follows: the method for this replacement sewage conduct, comprising the following steps:
(1) it constructs preplanning: according to job location and ambient enviroment facility, formulating science and detailed arrangement and method for construction and not
Same construction section；
(2) material and equipment prepare: all the setting for getting out required new tubing and construction needs is required according to scheme
Standby and tool.
(3) working pit is set: a certain size is arranged at each construction section both ends according to pipeline, equipment and personnel's space requirement
Working pit,；
(4) prepare before replacement: (2) ready material and equipment be placed individually into the working pit at construction section both ends,
And equipment is installed according to specified requirement；
(5) Material ports are handled: new pipeline being carried out to replace preceding pretreatment, including port processing, port connection etc.；
(6) old pipeline removes: being crushed old pipeline using broken and tube expansion tool, cleans out new Pipe installing space；
(7) new Pipe installing: new pipeline is installed according to original position using bench；
(8) it bankets back and buries: the soil of excavation being returned and is buried, is tamped, restore to the original state.
Since this method is that project amount is smaller, it is only necessary to excavate two working pits, method is simple and effective, has noise
The advantages such as life and work that is low, not influencing peripheral facilities and the masses, and engineering cost few to environmental disruption be low.
Specific embodiment
Below in conjunction with the embodiment of the present invention, the technical solution in the present invention is clearly and completely described, is shown
So, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
The method of this replacement sewage conduct, comprising the following steps:
(1) several construction sections are divided into according to the diameter difference and break of sewage conduct；
(2) the first working pit, the second working pit is respectively set at the both ends of each construction section；
(3) new pipeline is put into the first working pit, including port polishing, heat treatment, the pressure maintaining of new pipeline is cooling, so
One is melted under the effect of hydraulic Self-pressurizing agri afterwards, then by new pipe joint sweat soldering；
(4) trombone slide machine equipment is installed in the second working pit；
(5) broken and tube expansion tool is inserted into old pipeline from from the second working pit, carries out the broken of old pipeline, makes brokenly
The diameter of the tube expansion head of broken and tube expansion tool is greater than the diameter of old pipeline.Enough rings are provided when purpose is to replace pipeline
The frictional force between the new pipeline of replacement and stratum is reduced in border space；
(6) new pipeline is pulled in the position of old pipeline using trombone slide machine equipment.The tube expansion tool of a cone is inserted
Enter in old pipeline for guide, rupture old pipeline by pulling force, broken pipeline fragment is squeezed into soil around, using bench
New pipeline is pulled in old pipeline position by equipment, completes the replacement construction of sewage conduct.
It is noted that the setting of working pit should avoid road and business doorway, facilitate resident trip；It is one with caliber
Section；Pipeline has another point one section of break, when replacement pulling force is excessive, in fact it could happen that nozzle is staggered, and Xiu Zhihou is replaced again.
Preferably, new pipeline uses high density polyvinyl-chloride tubing.That is PE tubing, feature be it is corrosion-resistant, high temperature resistant, do not tie
Dirt, service life are long.
It is constructed using this method, solves the problems, such as that the eighties, sewage conduct was leaked because of pipeline aging, maintenance replacement ground
When underground pipelines, construct without " belly breaking " again.This method has operation side small, digging-free, and short construction period is comprehensive
It closes at low cost, many advantages, such as being widely used, the interference to traffic and the pollution to environment can be reduced to the maximum extent, reduced
Construct the bring sorrow people, reduces the destruction criss-cross to surrounding building basis and underground utilities, reduces construction cost.
To the protection fee and removal expense of underground utilities when reducing excavation simultaneously, abolishes old pipe and more renew pipe and once complete, short time limit is comprehensive
It closes at low cost.
Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, shall fall within the protection scope of the present invention.
