1)For the transformation of old and old pipeline facilities, it can meet the needs of structural renewal and expansion at the same time;

2) Avoid the trouble of demolition and damage to the environment to the greatest extent, and reduce the additional investment of the project;

3) Partial excavation of working pits reduces the amount of excavation and the impact on the public transportation environment;

4) Adopt hydraulic equipment, low noise, meet environmental protection requirements, reduce disturbing factors, and significantly improve social benefits;

5) The construction speed is fast and the construction period is short, which effectively reduces the project cost;

6) The project is safe and reliable, which improves the service performance and is beneficial to the later maintenance of the facility.

In view of the advantages of trenchless pipeline repair technology, investment in drainage pipelines, water supply stations and natural gas pipeline innovation has greatly increased in recent years. Although the economies of many European countries have a downward trend, the pipeline repair industry is becoming more and more prosperity.

3. Trenchless repair technology for pipelines

At present, there are three types of more advanced pipeline trenchless repair technologies in the world (including more than 10 kinds of technology), one is to use resin curing method to form new drainage pipes inside the pipeline, such as CIPP, on-site curing and other processes ; One type is to use small pipes to pass through large pipes, and insert small drainage pipes inside the original pipes to solve urgent needs, such as short pipe lining, U-shaped pipe dragging and other processes; the latter type is to use spiral pipes The way is to form a new pipeline inside the original pipeline by winding method, such as spiral winding method.6051bd01436cb.jpg
