Description
Technical field
The present invention relates to urban discharging pipeline recovery technique field, in particular to the method for non-excavation rehabilitation drainage pipeline and
Dedicated stainless steel inner lining repairs structure.
Background technique
While drainage pipeline facility amount rapid growth, quantity are increasingly huge, pipeline of the remote past is largely built still
So using.
And during drainage pipeline runs use, wastewater flow sequence, road caused by being damaged because of drain pipeline structure
The accidents such as ponding, water pollution and land subsidence happen occasionally.Especially when tunnel, subway etc. pass through draining using shield-tunneling construction
When pipeline, the disturbance of the soil body is easier that drainage pipeline joint is made to misplace, or even phenomena such as deformation, fracture occurs, once hair
It is raw, city daily life, production and shield-tunneling construction will be caused to seriously affect.
The non-excavation rehabilitation of drainage pipeline is to pass through drainage pipeline electricity before pipeline configuration development of defects becomes accident
Depending on the methods of sonar detection, pipeline configuration defect hazard rating is confirmed, the drainage pipeline more serious to structural failure carries out
Non-excavation rehabilitation restores pipeline and uses function, extends pipeline service life.Meanwhile it can preferably solve soil body loss, underground water infiltration
The problems in puzzlement sewerage system operational management such as leakage.
In practical applications, existing drainage pipeline no-dig technique integral restoration method mainly has: water cure method, ultraviolet light
Solidification method, mechanical spiral winding method etc..
Wherein, water cure method, ultraviolet curing method are not suitable for repairing large-caliber drainage pipeline, generally reparation largest tube
Diameter is 1200~Φ of Φ 1800, and buckling phenomena easily occurs in interface during pipeline rehabilitation, influences the use function of pipeline；It is mechanical
The loss of pipeline water pipeline is larger after spiral winding integral repair technology is repaired, and pipe drainage ability is declined after reparation.
Therefore, how the large-scale pipeline for caliber at 1800 millimeters or more carries out non-excavation rehabilitation as art technology
Personnel have a technical problem to be solved.
Summary of the invention
In view of the above drawbacks of the prior art, the present invention provide non-excavation rehabilitation drainage pipeline method and it is dedicated not
The steel lining that becomes rusty repairs structure, and the purpose of realization is to solve conventional non-excavation rehabilitation technique not being suitable for large-diameter steel reinforced concrete row
The technical issues of waterpipe is integrally repaired, the angle designed from structure, has ensured the bearing capacity of pipeline, has extended pipeline
Service life；Suitable for passing through the significant obstacles object such as subway, railway, main sewer, and the big mouth of trenchless rehabilitation can not be carried out
Diameter drainage pipeline is integrally repaired.
To achieve the above object, the invention discloses the method for non-excavation rehabilitation drainage pipeline, steps are as follows:

The brick wall of closure；The water of the ducts upstream to be repaired is imported into downstream line by temporary drainage measure simultaneously；
B, pipe dredging and cleaning: by silt pumping car draw water in the way of, dredging of drawing water is carried out to the pipeline to be repaired, dredge
Lead to the pipeline to be repaired；
C, telephotography detects: television pickup equipment being put into pipeline to be repaired, is detected to pipeline inside, institute is obtained
State the position damaged in pipe-repairing and damaged condition；
D, segment prefabricated: stainless steel plate raw material being pressed to the diameter of pipeline to be repaired, is rolled into corresponding tubular structure；And institute
It states and is positioned on tubular structure and injected hole is set；The tubular structure is cut into parts the identical arch plate knot of several shapes
Behind the section of jurisdiction of structure, the reparation scene of the pipeline to be repaired is transported to；
E, pipe joint and local damaged location reparation: according to telephotography testing result, to the pipeline to be repaired
Local damage position and/or interface damaged part carry out pre- repair process；That is, at interface damaged part or local damage position
Upstream and downstream tube wall installs cyclic annular rubber water-proof band respectively；
F, section of jurisdiction is mated formation and is welded in pipeline: one by one by several sections of jurisdiction from the decentralization of inspection shaft position enter it is described to
Pipe-repairing by stainless steel substrates welding in the tubular structure in pipeline, and checks weld seam；
G, it slip casting: is fixed between the tubular structure and the inner wall of the pipeline to be repaired using hardening slurry filling；
The hardening slurry nationality is injected out of described tubular structure by the injected hole；By the slip casting after hardening slurry solidification
Hole is blocked with bolt；
H, restore water flowing: removing the brick wall after hardening slurry solidification, restore water flowing；
I, telephotography check and evaluation: the shape of nationality tubular structure as described in telephotography detection system acquisition water flowing engineering
State saves filing as the image data after reparation.
Preferably, the local damage position be include leakage and/or pipe wall crack.
Preferably, the diameter of the diameter of the pipeline to be repaired is at 1800 millimeters or more.
Preferably, in step G, local damage position and/or interface of the hardening slurry through the pipeline to be repaired are broken
Damage position penetrate into the periphery soil body, it is described penetrate into the periphery soil body range include 1000 millimeters of the pipeline radius to be repaired extremely
2000 millimeters of region.
The present invention also provides the dedicated stainless steel inner lining reparation structures of the method for non-excavation rehabilitation drainage pipeline institute, including by
The tubular structure of several section of jurisdiction compositions；The side wall of the tubular structure is equipped with several injected holes；The pipe
The local damage position and/or the interface damaged part of the shape structure setting in the pipeline to be repaired；The tubulose knot
