Description

Technology Field

[0001] The present invention relates to the field of construction technology, and more specifically, to a concrete pipe reinforcing member and a concrete pipe reinforcing method using the same. Background Technology

[0002] Generally, sewer pipes, wastewater pipes, and stormwater pipes are constructed as concrete conduits.

[0003] However, over time, concrete pipes suffer damage such as internal cracks, spalling, and breakage.

[0004] In this case, damage may cause sewage, wastewater, and rainwater to leak from within the pipe, and the leaked sewage, wastewater, and rainwater may cause ground subsidence, leading to sinkholes.

[0005] To address these issues, the interior of pipelines is being repaired using steel plate or fiber reinforcement; however, steel plate reinforcement has the problem of being heavy and prone to corrosion, while the fiber reinforcement method suffers from poor durability due to the weak rigidity of the fibers.

[0006] Prior art for solving this problem includes Korean registered patent No. 10-2006-0014302 'Repair method inside a pipeline', Korean registered patent No. 10-2010-0079441 'Repair and reinforcement method for pipelines and concrete structures using reinforced plastic segment lining method', and Korean registered patent No. 10-2010-0078108 'Non-excavation sewer pipe partial repair method using underwater-curing epoxy resin paint and flexural expansion repair device'.

[0007] Specifically, looking at the prior art, first, Korean registered patent 10-2006-0014302, 'Repair method inside a pipe,' is a repair method inside a pipe that includes: a foreign matter removal step in which foreign matter inside a pipe (10) is removed by spraying pressurized water at high water pressure by a pressurized water spraying device (100); and a concrete pouring step in which concrete is poured into the inside of the pipe (10) from which foreign matter has been removed by a spraying method.

[0008] Korean Registered Patent No. 10-2010-0079441, 'Repair and Reinforcement Method for Pipelines and Concrete Structures Using Reinforced Plastic Segment Lining Method,' relates to a repair and reinforcement method for underground pipeline structures and above-ground structures using a reinforced plastic segment lining method, and more specifically, to an arc-shaped or spherical reinforced plastic segment used therein and a repair and reinforcement method for underground pipeline structures or above-ground structures using the same.

[0009] Korean Registered Patent No. 10-2010-0078108, 'Non-excavation sewer pipe partial repair method using underwater-curing epoxy resin paint and bendable expansion repair device,' relates to a sewer pipe partial repair method in which a repair portion existing in a wet state or underwater is repaired using a non-woven fabric tube impregnated with underwater-curing epoxy resin paint and a bendable expansion repair device in a sewer pipe that requires partial repair due to cracks in buried sewer pipes or detachment of pipe joints.

[0010] However, among the prior art, Korean registered patent 10-2006-0014302 'Repair method for the interior of a pipeline' and Korean registered patent 10-2010-0078108 'Partial repair method for trenchless sewer pipes using underwater-curing epoxy resin paint and a bending expansion repair device' are reinforcement technologies that apply a reinforcing composition (concrete or epoxy resin) to the inner surface of a pipeline, but a problem arises in that the adhesion between the interior of the pipeline and the reinforcing composition decreases after application, and Korean registered patent 10-2010-0079441 'Repair and reinforcement method for pipelines and concrete structures using a reinforced plastic segment lining method' is complex to construct and has a problem of poor workability inside narrow pipelines.
