Description

Technical Field

[0001] The invention relates to the technical field of pipeline damage repair, and in particular to a sewage pipeline damage repair device. Background Art

[0002] The sewage pipe damage repair device is a device specially designed to repair damaged or leaking sewage pipe systems. It can perform precise repairs on the inside of the sewage pipe without digging up the road.

[0003] Most of the devices currently on the market that can repair the inside of sewage pipes are equipped with an airbag support. A tubular repair layer of glass fiber material impregnated with oil resin is sleeved on the outside of the airbag support. A walking mechanism is used to drive it to move inside the sewage pipe. The device is also equipped with an endoscope, which is used to determine the location of the damage. The airbag support is inflated to make the repair layer adhere to the inner wall of the sewage pipe, thereby achieving the repair operation.

[0004] However, by tightly adhering the repair layer to the inner wall of the sewage pipe in a cylindrical manner, there will be a certain area of ​​gap between the repair layer and the damaged sewage pipe in the outer space, which will result in the damaged part after repair being isolated from the external environment only by a single repair layer, making the repair layer here relatively weak and prone to damage again at a later time, which will lead to the problem of poor repair effect.
