Rehabilitation Trenchless Technology Training Underground Sewer Water CIPP Inversion Equipment

Trenchless rehabilitation of underground sewer by water inversion CIPP technology

The number of underground pipe networks in former cities is increasing. According to the construction and operation monitoring results of drainage pipelines, a large number of drainage pipelines have structural and functional defects due to the early chaotic pipe market, immature technical standards, unqualified construction quality, inadequate pipe maintenance and management, and long service life.

The operation and maintenance of drainage pipelines is the weak link of urban infrastructure at present, and the repair of the defective pipelines has become a hot issue of urban facility maintenance. Based on this, Daoyunai company puts forward the trenchless repair construction materials, namely CIPP water inversion and solidification process, according to the diseases of sewage pipe network in urban built-up areas through examples, including the construction process and technical characteristics, and evaluates the actual repair effect, so as to provide design reference for the large-scale trenchless repair of drainage pipes in cities in the future.

Features:

1-Good compatibility: using high-quality resin and additives, each component has good compatibility, mixed evenly, fully infiltrated the pipe, and there is no delamination after curing.

2-High mechanical properties: accurate calculation of resin dosage, adding inorganic powder filler as required to improve mechanical properties.

3-Formula Customization: strictly avoid fat extraction and solid lattice sample preparation for the solid tree. The chemical situation control and inspection department will always prepare and test the root products. According to the quality of the whole bank, or adjust each batch of blasting workers to avoid times;

4-Storage for 3 days: it can be stored for 3 days at low temperature and can be transported for a long distance.

5-Curing control: effectively control the curing process to avoid swelling caused by overheating, gasification, foaming, peeling or incomplete curing.

6-Technical background: the core technicians have a deep background in polymer materials and are familiar with the characteristics and applications of materials.
