As the quick coupling means utilized in the present invention, various known methods can be utilized, and a detailed description thereof will be omitted.

- Injection cylinder (300)

As shown in FIGS. 2A and 2B, the injection cylinder 300 is connected to the fixed anchor 100 and continuously applies pressure to the perforation hole (not shown) to inject the rust inhibitor for a predetermined period of time , It is important to provide a means for continuously applying pressure.

The injection cylinder 300 includes a housing 310 having a hollow interior and a piston 310 disposed inside the housing 310 to divide the rustproofing material filling space 330 and the elastic spaces 340 and 350, A piston ring 321 fitted in the groove formed in the side of the piston 320 to maintain the airtightness between the piston 320 and the housing 310 and an anti- A rustproofing material injection port 311 provided at the upper end of the housing 310 for injecting the rustproofing material into the first elastic space 340 and the second elastic space 350 in the upper and lower spaces, One or more elastic balls 370 to be filled in the first elastic space 340 and one or more elastic springs 380 to be fitted in the second elastic space 350 .

The lower end of the housing 310 is provided with a fitting hole 312 and is fitted into the fitting hole 312 to be fixed to the lower end of the separating disc 360 to return the separating disc 360 by an external force. Retraction means 314 may further be provided.

In the present invention, the rust inhibitor is injected through the rustproofing agent inlet 311. The rust inhibitor is injected by pressing the piston 320 of the injection cylinder 300 by a rust preventive injection pump (not shown) (330). However, in this case, since the rust prevention agent must be filled while pressing the piston 320, the pumping force of the rust inhibitor injection pump (not shown) must be very strong, which may be inefficient.

Accordingly, in the present invention, the piston retracting means 314 that is thermally coupled to the separating disk 360 is provided, and the piston retracting means 314 is used to remove the rustproofing agent from the separating disk (not shown) 360 to retract the elastic spring 380 of the second elastic space 350 to relieve the pressure exerted by the rust preventive injection pump (not shown). The piston retracting means 314 can be used for various purposes such as a string, a rod and a rod. The housing 310 is provided with a piston retracting means 314 for retracting the separating disk 360, Preferably, a latch is provided to secure the means 314. Of course, since it is also possible to rapidly inject the rust inhibitor into the injection cylinder 300 in a pulled state, the provision of the latch is not essential.

5B, the piston retracting means 314 is provided as a string and the end thereof is formed in a T shape as shown in FIG. 5B. The piston retracting means 314 is retracted, It is possible to adopt a method of catching the latch 313 provided on the outer circumferential surface of the housing 310 while enclosing the outer circumferential surface.

The injection cylinder 300 uses at least one of two types of elastic bodies, that is, the elastic balls 370 and the elastic springs 380, in order to reinforce the elastic force. In the present invention, it is most ideal to inject the rustproofing agent with a predetermined pressure with a perforation hole (not shown). In the present invention, when the rustproofing agent is injected by generating pressure by itself without a separate external force, It is possible to supply a certain amount of elastic force to a plurality of elastic bodies by applying an elastic force using a maximum number of elastic bodies so as to minimize a reduction in pressure due to a reduction in elastic force.

The elastic ball 370 filled in the first elastic space 340 may be an elastic ball made of various materials. There is no limitation on the gas filled in the elastic ball 370, but the elastic ball 370, which can provide an appropriate pressure for the purpose of the present invention Any gas is irrelevant. The gas may be a pure gas, a mixed gas, or the like.

In addition, a pressure gauge 391 is provided in the rustproofing agent inlet 311 of the injection cylinder 300 to measure the pressure generated by the injection cylinder 300 in real time.

In addition, a cylinder valve 392 is provided in the rustproofing agent inlet 311 of the injection cylinder 300 to control injection and release of the rust inhibitor. In particular, when the rust preventive agent injection pump (not shown) is connected to the injection cylinder 300 to charge the rust preventive agent and the rust preventive injection pump (not shown) is disassembled, the cylinder valve 392 must be essentially locked, It is possible to prevent the rust inhibitor from leaking due to the self-pressure of the gasket 300. Of course, when the injection cylinder 300 is connected to the fixed anchor 100 and the rustproofing agent is injected, the cylinder valve 392 must be opened.

- connecting piping (200)

The connection pipe 200 is communicated with the fixing anchor 100 at one end and communicated with the injection cylinder 300 at the other end to guide the injection of the rustproofing agent and includes an optional component to be.

The fixed anchor 100 is vertically inserted into a perforation hole (not shown) provided on an outer wall of a vertically installed reinforced concrete structure and is fixed to the outer wall. The fixed anchor 100 is connected to the injection cylinder 300, When the injection cylinder 300 is connected to the fixed anchor 100 perpendicularly to the outer wall of the structure, excessive moment is exerted on the connection portion between the fixed anchor 100 and the injection cylinder 300 due to its own weight The rust preventive injection device may be damaged.

The connection between the fixed anchor 100 and the injection cylinder 300 may be connected using a bendable pipe so that the injection cylinder 300 is suspended from the outer wall of the reinforced concrete structure.

Further, a magnet 210 surrounding the outer circumferential surface of the connection pipe 200 is provided to smoothly guide the flow of the rust inhibitor guided to the connection pipe 200.

Any object is made up of a collection of units called molecules, each of which has a natural vibration. One molecule consists of several atoms, which are not bonded together, but continue to move, and this movement causes molecular vibration (Brownian motion effect). Magnets wrapped around the outer circumference of the pipe give 'interference vibration' to this fundamental vibration, and vibration generated from the magnet suppresses and removes the generation of rust and scale, and this effect spreads evenly in a very short time in the pipe. With this principle, the inner diameter of the pipe can be restored at a high speed, thereby facilitating the flow of the fluid into the pipe.

As a result, the vibration generated by the magnet gives the effect of interference, so that the magnitude of the vibration of the scale components dissolved in the fluid becomes smaller, so that the scale does not reach the saturated state and the scale is not precipitated. Melted and discharged quickly. Figure 1 is a conceptual diagram showing the effect of the magnet ring.
