Description
Technical field
The present invention relates to pipeline rehabilitation fields, the more particularly, to restorative procedure of concrete duct sedimentation leakage.
Background technique
Concrete duct and PCCP concrete duct, because cheap, the municipal plumbing field largely applied,
It is buried to underground, is used as conveying water supply and draining.But over time, the disease of concrete duct more and more exposes
Out, it is mainly shown as that joint sealing is unreliable, is easy leakage, instant PCCP steel drum prestressed concrete pipe road, connector uses
The reliability of bell and spigot, sealing is also high；In addition, bodies splittable leaks, main cause is that concrete is not impervious coagulation
Soil, water are contacted through concrete cover with the reinforcing bar of inner barrel or steel drum, and after of long duration, the pH value of concrete cover subtracts
It is weak, lose the protective effect to internal reinforcing bar or steel plate.Protective layer, must to play the protective effect to internal reinforcing bar and steel plate
It need ask protective layer that there is certain intensity and impermeability, otherwise its protective effect will be temporary, once lasting water penetrates into
The inside concrete of protective layer will lead to pH value and decrease up to neutrality, to lose the protective effect institute to interior metal building
With the various defect problems of appearance of the concrete duct of 10 years inbuilt undergrounds of China all one by one now, so as to cause infiltration
Leakage takes place frequently.Concrete duct leakage is mainly caused by two parts, first is that the Seal Design reliability of pipe joint is very low, it is slightly heavy
Drop occurs, and will cause to leak；Second is that tube body concrete pouring quality is bad or steam enters concrete, cause interior metal
Building corrosion expansion, causes concrete to fall off, and then cause leak.If concrete duct is used as conveying sewage, because seeping
Leakage causes underground water pollution;If being used to convey water supply, it will cause flow loss.
Summary of the invention
The problem of being easy sedimentation, leakage present invention aim to address existing concrete duct, can greatly improve interior
The sealing performance of lining, the service life for extending pipeline are particularly suitable for buried concrete pipeline, PCCP pipeline, cast-iron pipe etc.
Reparation.
In order to achieve the goal above, the technical solution adopted by the present invention is that: a kind of concrete duct sedimentation leakage reparation side
Method, comprising the following steps:

Polyurethane injecting paste material, after the completion of injection, after the concrete duct wait settle is promoted to the same horizontal position, with expansion water-stop rubber
Rubber plug inserts in the hole；
Step 2: pipeline junction reparation after treated in step 1 pipeline deviation rectification, is filled out in pipe joint gap
Filling high-intensitive impervious mortar, then correspond to seam crossing in inner wall of the pipe passes through redundancy waterproof adhesive sealing rubber belt with bond；
Step 3: inner wall of the pipe reparation, inner wall of the pipe that treated in step 1 have crackle and dew muscle portion position spraying waterproof anti-
Special sizing agent is seeped, sprays two component polyurethane for local leak source；
Step 4: being coated with protective layer, multiple by redundancy waterproof adhesive bonding in inner wall of the pipe that treated in step 3
Close splash guard.
