Description

Mending Apparatus and Mending Method for Non-digging Sewerage

The present invention relates to a non-excavated water and sewage pipe refurbishment tube reinforcement support device, and more specifically to the reinforcement tube inverted into the water and sewage pipe reversing device and the check curing device to cure the reinforcement tube to facilitate the reinforcement by combining and separating When the tube is hardened, the reversing device is separated to shorten the road occupancy time of the vehicle equipped with the reversing device, while reducing the construction cost by shortening the reinforcing tube curing time and limiting the reversal length of the reinforcing tube that is reversed to the water and sewage pipe. Non-excavated water and sewage pipes to reduce the reinforcement tube to the overall repair reinforcement tube reverse support device and repair method.

Various water supply and sewage pipes buried in the ground gradually deteriorate with time, causing problems in the water pipes due to corrosion, and enormous amount of water leaks. Drinking water is contaminated by the rust that flows into the pipes. In this case, cracks are generated, and sewage flows out of the pipe to pollute the living environment such as soil and groundwater.

As described above, in repairing the old buried pipelines in which damage such as cracks have occurred, the non-excavated pipeline repairing device and construction method do not dig the ground, and insert a reinforcement tube into the old buried pipelines in which the cracks occur, thereby creating a new composite pipe in the sewer pipe. As a construction method to be formed, there is no need for road restoration construction, and thus, the construction method has many advantages in terms of workability, reliability, and economy.

In general, the unexcavated pipeline repairing and construction method is a method of inserting and fixing a reinforcement tube formed of a waterproof coating layer or a film layer and an adhesive resin impregnated felt layer into an old buried pipe. The reinforcement tube is inverted into the buried pipe in the surface state so that the inner surface of the buried pipe impregnated felt layer is inverted to the surface and bonded to the inner wall of the buried pipe, and the reinforcing tube is coated on the inner wall of the buried pipe.

Among them, the method of hardening the reinforcement tube with hot water after inserting the hydraulic reversal, which takes a long time to cure, may cause damage to the sewage of home sewage, and the extension of the tube on the end when the inclined pipe is constructed increases the size of the reinforcement tube. The problem of thickness nonuniformity arises.
