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.
