Fiberglass pre-impregnated resin for underground sewer by CIPP no excavation

How to install the packer?

Protect the stainless steel binding head with a film to avoid contact with the resin.

To ensure the fastening of the binding head, cut a small opening with a length of about 5cm in the middle 12 o'clock direction.

Bind two layers. Finally, two tie ropes are tied at the tail of the tie head for lowering into the well.

After all the hoses are pulled into the pipe, the other section begins to bind stainless steel binding heads.

Pay attention to the binding parts at both ends, and place the binding cloth (the diameter of the binding cloth is the same as the material, and the length should be 70-80cm). Protect the built-in light rope, and use a rope to fix the built-in rope separately.

After all the hoses are in place, cut the opening of the first layer about 5cm in the direction of 12 o'clock at both ends for air exhaust during air blowing.

If there is accumulated water at the bottom of the inspection well, the tie head shall be padded with wood and other auxiliary materials to prevent water from entering the material. At the same time, the drainage pump shall be used to drain the excess accumulated water at all times.

At the same time, use the rope built into the material to pull the lamp rope into the pipe.
