The present invention relates to a sewage pipe joint non-excavation repair device and construction method in a manhole, and more particularly, to a sewage pipe joint non-excavation repair device and construction method in a manhole capable of repairing a junction between a manhole and a pipe.

In general, a sewage pipe for treating wastewater discharged from homes or businesses, a stormwater pipe for discharging rainwater into a river, or a confluence pipe through which sewage and rainwater are combined are buried underground. It's called a sewer pipe. A plurality of such sewage pipes are connected and used to move rainwater or wastewater to a sewage treatment plant or a river.

However, the sewage pipeline deteriorates over time and cracks are generated, or wastewater leaks to the outside due to cracks, breakage, or separation of the connection part, which can cause environmental pollution such as soil contamination, as well as sludge or flow from the outside. Foreign substances accumulate, and odors are generated by foreign substances, sludge, and sediment.

When repairs are required for abnormal areas such as partial damage to a pipeline buried underground, a gap or a step at the joint of the pipeline, or a lifting phenomenon due to shrinkage of the resin on the repair material during the curing process. As a construction method for repairing under the condition of being buried in the There is a lining partial repair method, which is applied and impregnated, then hardened and partially repaired.

In accordance with the operation of the cylinder member, the compression member coupled to at least one of the flange member and the body frame presses the expandable member to bring the repair material into close contact with the junction of the manhole and the conduit,
The compression member is a sewage pipe joint non-excavation repair method in a manhole, characterized in that provided in a foldable manner so that at least one portion of the compression member is folded. The main body frame is introduced into the conduit to which the manhole is coupled;
The step of expanding the expansion member coupled to the flange members respectively coupled to both ends of the body frame and spaced apart from the body frame to receive a fluid supply between the body frame;
a step of attaching a part of a repair material wound along the circumference of the expandable member and comprising at least two parts so as to be in close contact with the manhole and the pipe to the pipe according to the expansion of the expandable member;
operating the cylinder member disposed inside the body frame and supported, coupled to the flange member, and provided to be stretchable; and
In accordance with the operation of the cylinder member, the compression member coupled to at least one of the flange member and the body frame presses the expandable member to bring the repair material into close contact with the junction of the manhole and the conduit,
In order to reduce the weight of the compression member, at least one through hole is formed in the compression member. 10. The method according to claim 8 or 9,
The repair material is
a first portion wound to be in close contact with the periphery of the expandable member; and
a second portion extending from the first portion and spaced apart from the expandable member;
When the expandable member expands and the first part of the repair material is attached to the pipeline, the compression member presses the expandable member, and the expandable member pressed by the compression member presses the second part of the repair material and attaching to the manhole to repair the damaged portion of the junction of the manhole and the pipeline.
