Abstract
The invention discloses a kind of urban Underground pipeline non-excavation rehabilitation dredging methods, belong to pipe rehabilitation technology field.Include the following steps: step 1: pipeline cleaning；Step 2: base-material spraying；Step 3: binder cures.Using in the pipeline of no-dig technique cleaning combine photocuring technology can effectively reduce construction surface excavate area and shorten the construction period.
Description
Technical field
The invention belongs to pipe rehabilitation technology fields, are a kind of urban Underground pipeline non-excavation rehabilitation dredgings specifically
Method.
Background technique
Urban Underground pipeline reparation usually requires the excavation project of large area, and there are workload is huge and the skills such as duration overlength
Art problem.
Summary of the invention
Object of the present invention is to be intended to provide a kind of solution insufficient urban Underground pipeline non-excavation rehabilitation in the prior art
Dredging method.To realize the above-mentioned technical purpose, The technical solution adopted by the invention is as follows:
A kind of urban Underground pipeline non-excavation rehabilitation dredging method, includes the following steps:
Step 1: pipeline cleaning；
Step 2: base-material spraying；
Step 3: binder cures.
It further limits, inner wall of the pipe is cleaned using high pressure nozzle, while using suction pump to the silt in pipeline
Plug thing is drained.
It further limits, cleaning Fluid pressure is greater than 50MPa.
It further limits, base-material is sprayed on tube wall after cleaning, base-material is light-cured resin.
It further limits, is passed through hot-air in pipeline before spraying base-material, inner wall of the pipe is dried.
It further limits, is being passed through hot-air while polishing inner wall of the pipe, inner wall of the pipe is made to form rough surface.
It further limits, base-material thickness is not less than 5mm.
It further limits, base-material, which is sprayed while being irradiated using ultraviolet light, to be solidified.
It further limits, base-material is acrylic resin, the acrylate of acroleic acid esterification, polyurethane acroleic acid tree
One of rouge, polyester acrylate resin, polyoxyalkylene acrylate resin or a variety of mixtures.
Compared with prior art, tube wall cleaning can use PIG industry pigging technology to the present invention, push fluid to generate by pump
Promotion power drive PIG (pipe cleaner) in pipe to preceding promotion, by outside the dirt discharge pipe for accumulating in-line, to reach clear
The purpose washed.The technology is widely used in the cleaning works such as all kinds of process pipes, oil field oil transportation gas pipeline, especially for length
Pipeline cleaning apart from trandfer fluid, has the irreplaceable advantage of other technologies, and the cleaning fluid used can be chemistry
Reagent or water flow can effectively reduce and excavate area to cleaning pipeline；
Carrying out tube wall solidification in combination with photocuring technology can greatly shorten, the construction period.
Specific embodiment
The embodiment of technical solution of the present invention will be described in detail below.Following embodiment is only used for clearer
Ground illustrates technical solution of the present invention, therefore is only used as example, and not intended to limit the protection scope of the present invention.
It should be noted that unless otherwise indicated, technical term or scientific term used in this application should be this hair
The ordinary meaning that bright one of ordinary skill in the art are understood.
A kind of urban Underground pipeline non-excavation rehabilitation dredging method, includes the following steps:
Step 1: pipeline cleaning；
Step 2: base-material spraying；
Step 3: binder cures.
Inner wall of the pipe is cleaned using high pressure nozzle, while the object that silts up in pipeline is drawn using suction pump
Stream.It cleans Fluid pressure and is greater than 50MPa.Base-material is sprayed on tube wall after cleaning, base-material is light-cured resin.In spraying base-material
It is preceding that hot-air is passed through in pipeline, inner wall of the pipe is dried.It is being passed through hot-air while polishing inner wall of the pipe, making
Inner wall of the pipe forms rough surface.Base-material thickness is not less than 5mm.Base-material, which is sprayed while being irradiated using ultraviolet light, to be solidified.
Base-material is acrylic resin, the acrylate of acroleic acid esterification, polyurethane acrylic resin, polyester acrylate resin, gathers
One of ether acrylic resin or a variety of mixtures.
Compared with prior art, tube wall cleaning can use PIG industry pigging technology to the technical program, push fluid by pump
The promotion power drive PIG (pipe cleaner) of generation in pipe to preceding promotion, by outside the dirt discharge pipe for accumulating in-line, to reach
To the purpose of cleaning.The technology is widely used in the cleaning works such as all kinds of process pipes, oil field oil transportation gas pipeline, especially pair
In the pipeline cleaning of long distance delivery fluid, there is the irreplaceable advantage of other technologies, the cleaning fluid used can be for
Chemical reagent or water flow can effectively reduce and excavate area to cleaning pipeline；
Carrying out tube wall solidification in combination with photocuring technology can greatly shorten, the construction period.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme should all cover within the scope of the claims and the description of the invention.
