Embodiment Construction

[0021] [19] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0022] [20] [First embodiment]

[0023] [21] The obturator 30 of the present invention includes the injection body 10 and the flexible sleeve 20 assembled together. An inflow channel 11 is formed through the injection body 10 in the longitudinal direction. A joint portion 12 is formed at one end of the injection body 10, and a plurality of extension units 13 are continuously formed at the other end of the injection body 10, each extension unit having a trapezoidal section such that its diameter gradually increases from its front end to its rear end. A backflow prevention groove 11' having a larger diameter than the inflow passage 11 is formed at an end of the inflow passage 11 opposite to the joint portion 12, and a backflow prevention unit 17 including a compression spring 17b and a spherical check ball 17a is formed in the backflow preven...

Abstract

Disclosed is a packer for repairing a crack in a concrete body. The packer includes an injection main body and a soft sleeve. The injection main body includes an inflow route, a nipple part, a plurality of extension units, each of which has a trapezoidal section injection main body, and a backward flow prevention unit in the end of the inflow route opposite to the nipple part. The packer is obtained by assembling the soft sleeve with the extension units of the injection main body, and is installed along the crack of the concrete body, thus easily repairing the crack in the concrete body.

Description

technical field [0001] [01] The present invention relates to a packer for repairing cracks in concrete structures, and more particularly, to a packer for repairing cracks in concrete structures, which includes an injection body and a flexible sleeve, and injects The main body includes an inflow passage formed longitudinally and a plurality of extension units continuously formed at one end thereof, each extension unit having a trapezoidal cross-section, the flexible sleeve having a hollow structure formed therein corresponding to the shape of the extension unit, And inserted into one end of the injection body, wherein, when the packer is inserted into the concrete structure along the crack and the resin solution is injected into the injection body, the injection body is partially pushed out with the flexible sleeve kept at its original position , whereby the flexible sleeve is uniformly expanded in the circumferential direction, so that leakage of the resin solution can be prev...
