Pipelines are a very important part of urban infrastructure. However, as the city progresses, the problem of damaged or aging pipes is becoming more and more serious, and it needs to be repaired. Traditional restoration methods often require excavation of the road surface, which not only affects traffic, but also causes damage to the surrounding environment. Therefore, trenchless repair technology came into being, among which ultraviolet curing hose repair technology is one of the important methods.
1. Advantages of trenchless repair technology.
1.No impact on traffic: Traditional excavation and repair methods require road closures, which has a significant impact on traffic. The UV-curable hose repair technology can be repaired without damaging the road surface, avoiding traffic congestion and traffic accidents.
2.Cost saving: excavation and repair require a large amount of earthwork excavation and backfill, which consumes a lot of manpower and material resources. The UV curing hose repair technology only needs to put the hose into the pipe to be repaired, and the repair can be completed through UV curing, which is relatively low.
3.Environmental protection: Traditional excavation and remediation methods will produce a large amount of construction waste and noise pollution. UV-curable hose repair technology produces less exhaust gas, waste water and noise, and has less impact on the environment.
2. The principle of ultraviolet curing hose repair technology.
UV-curable hoses have excellent corrosion resistance and mechanical properties. In the process of pipeline repair, the damaged pipe is partially cut off, and then the UV curing hose is placed into the pipe to be repaired, and the hose is solidified and tightly fitted with the inner wall of the pipe by ultraviolet irradiation, so as to complete the repair of the pipe.
3. The construction process of ultraviolet curing hose repair technology.
1.Pre-construction preparation: First of all, you need to clean the pipeline to be repaired to ensure that there is no debris and stagnant water in the pipeline. Then develop a repair plan based on the damage to the pipeline, and prepare the required equipment and materials.
2.Hose laying: Place the UV-cured hose from one end of the pipe and make sure it fits snugly against the inner wall of the pipe. If needed, the hose can be pulled into the pipe using equipment such as a towing vehicle.
3.Ultraviolet light irradiation: Place the UV lamp at one end of the hose and turn on the power to irradiate. During the irradiation process, it is necessary to control the time and distance of the light to ensure that the hose is fully cured and fits tightly to the inner wall of the pipe.
4.Quality inspection: After the curing is completed, the repair quality needs to be inspected to ensure that the hose fits snugly and the inner wall of the pipe is tightly fitted and there is no leakage. If there is a quality problem, it needs to be dealt with and repaired in time.
