Trenchless Spiral Wound Lining Equipment for Collapsed Drainage Pipes

Forming process:

Pipe material with steel-plastic compositestructure, excellent ring rigidity of thefinished product

Flexible specifications:

Quick mold change design. With just onepiece of equipment, different molds canbe switched to produce various diametersof pipes, meeting the requirements ofcustomers' multiple specifications orders.

Automated configuration:

Steel strips and PvC belts are automa-tically fed synchronously andcompatibly, with a high degree ofautomation.

Three-step linkageFull shape adaptation:Introduce three repair modes: fixed,walking,and expanding. They can flex-ibly adapt to circular, square andirregular pipes. They can precisely fit inall situations and solve the problems ofstructural rigidity and construction.They meet the diverse repair needs.

01

Pipeline cleaning was carried out and itscondition was confirmed through CCTV

inspection.

02

The spiral wrapping device tightly wrapsthe PVC profiles around the inner wall in aspiral shape. The interiocking edges ofeach special-shaped strip are.mechanically connected to form a

seamless structural lining

03

After the packaging is completed, theannular gap is filled with grout underpressure to ensure proper contoct and

structural integrity.

04

install the end sealing components andinspect the quality of the finished liningplates through CCTV to ensure that thepipeline is fiat, waterproot, durable and

readyfor use
