BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a leak detection repairing method such as a roof wall, and an apparatus thereof. In particular, the present invention makes it possible to quickly and easily and accurately find leaks such as concrete and sleeve roofs. The present invention relates to a leak detection repair method such as a roof wall, which facilitates repair, and an apparatus thereof.

In general, the leakage of a building after completion is not as desired as the leakage itself is not desired, and the ceiling material and the wall material are contaminated normally, and the appearance of the building is badly damaged. In this case, there is a situation where you cannot leave it alone.

Conventionally, the cause of a leak (namely, the channel 3 in FIG. 1) was very difficult to find, and the repair method was performed by each technician independently.

Typical examples are the method of laying the waterproof sheet on the entire rooftop, finding the leaky part of the rooftop at the leaked part of the ceiling surface, and forming a plurality of water injection holes in the enlarged peripheral area so as to be connected to the waterway. There is a method of hardening by pressing a waterproof adhesive into the waterway.

However, there is an unreasonable point that the former is to be repaired to a place other than the leaked portion, and the economic burden is also great.

The latter is to be repaired up to the unnecessary enlargement surroundings not by accurate grasp of the channel 3, and in this method, the hit ratio is not 100%, and the waste of renovation after testing is necessary. Had followed.

In addition, a very inefficient method is being repeated, such as deliberately conducting a test of watering the roof to find leaks.

In addition, in finding the leaked part, the concrete roof was beaten with a hammer to know the position of each other.

The present invention provides a process for forming a gas injection hole in a part of a leaked portion formed on an inner wall surface and an outer wall surface of a roof wall or the like composed of several layers; Injecting a predetermined gas into the gas injection hole; Detecting the gas and confirming leaks from each other; Forming a liquid inlet port from the outer wall surface to the channel; In the leak detection and repairing method of roof wall or the like, which is a process of injecting a waterproof adhesive from a liquid inlet and filling-hardening the entire waterway, the step of checking the leaked part includes installing an ultrasonic receiver on the inner wall and the outer wall, respectively. And a step of detecting the working position by ultrasonic waves, wherein the peripheral portion of the gas injection hole is closed with a fastener, and the gas injection hole is relatively deficient in the reactivity of the rare gas of a suitable temperature and a suitable pressure. And transporting the gas under pressure to detect the gas that permeates the outer wall surface through the water channel.

At this time, it is preferable that the relatively lacking reactivity gas is helium or carbon dioxide gas.

In addition, a detection gas generator including a gas cylinder, a pressure regulator composed of a gas valve, an opening / closing valve and a pressure valve at a lower part of a roof wall or the like to detect or repair a leak, and a nozzle and a power supply connected through the hose from the detection gas generator. In a leak detection and repair device such as a flag connected through a cord and a roof wall including a predetermined leak detection device on an upper part of the roof wall or the like, the predetermined leak detection device is a roof leak or the like. An ultrasonic oscillator installed on the inner wall surface, an ultrasonic receiver mounted on an outer wall surface (roof) such as the roof wall, receiving an ultrasonic wave from the ultrasonic oscillator, and a detection port connecting one end through a hose, It is characterized by consisting of the gas detector which integrated the detection buzzer inside, and the digital display system in which the digital display part (window) was formed.

EXAMPLE

Next, the concrete slide roof shown in the accompanying drawings for each embodiment of the present invention will be described.

When a crack (crack), rise, or settlement (concrete spacing) is found in the inner wall surface 1a 'of the wall 1 made of the concrete layer 1a, the waterproof layer 1b, and the pressed mortar layer 1c. First, the ultrasonic oscillator 10 is installed on a portion of the inner wall surface 1a 'formed with the approximate water immersion, and the ultrasonic receiver 12 is installed on the outer wall surface (roof) to check the upper and lower working positions. do.

The gas injection hole 2 is formed in the water leakage part of this inner wall surface 1a ', and the peripheral part of this gas injection hole 2 is closed with a quickener.

The detection gas generator 20 formed below the inner wall surface 1a 'of the building forms an opening / closing valve 22a on the upper part of the gas cylinder 22. The opening / closing valve 22a has a gas temperature, A pressure regulator 24 is formed, and the regulator 24 is provided with a pressure valve 24a and a pressure gauge 24b, and the regulator 24 has a hose 26 having a nozzle 26a at its front end. The base is connected, and the base of the power cord 28 having the plug 28a at the front end is connected again.

The gas detector 30 formed on the roof mortar layer 1c is connected to the base of the power cord 32 having the plug 32a at the front end, and the hose 34 having the detection port 34a at the front end. The base end hole is connected to the digital display system 36 in which a detector buzzer is built in the main body of the detector 30 and a switch (not shown) is formed in a required portion of the surface.

The digital display part (window) 36a is formed in front of this digital display system 36. By fitting the detection port 34a of the gas detector 30 on the outer wall surface 1c 'of the rooftop, it is possible to inhale and detect the gas passing through the channel 3 from the inside.

Discover leaks in advance (when intervening with ceiling plates, remove those ceilings from the water inundation and find those leaks on the inner wall surface 1a of the wall 1, A gas injection hole 2 having a size and depth is formed, and other portions are closed in a sealed state by a fastener, a tape, or the like, and the temperature injection pressure is applied to the gas injection hole 2 from the nozzle 26a of the detection gas generator 20. The gas for detecting the gas deficient in the relatively reactive gas is pumped.

If necessary, this detection gas is helium, carbon dioxide gas, or other inert gas.

Jack of the power outlet which partially inserts the nozzle 26a of the detection gas generator 20 into the gas injection hole 2 as mentioned above, and requires the plug 28a of the power cord 28 of this detection gas generator. (Not shown), the detection gas of the cylinder 22 is heated to a predetermined temperature by an internal heat resistance wire (not shown), and the opening / closing valve 22a is opened, and a suitable pressure (usually 1Kg / cm 2 to 2Kg) is applied. / Cm 2), for example, carbon dioxide gas, is pressurized through the hose 26 from the diesel fuel injection nozzle 26a into the gas injection hole.

Alternatively, the ultrasonic receiver 12 and the gas detector 30 are disposed on the mortar layer 1c, and the plug 32a of the power cord 32 is inserted into a jack (not shown) of a predetermined power outlet and arranged to each other. do.

In this way, the carbon dioxide gas flowing into the upper portion from the passing mortar layer 1c through the channel 3 is sucked through the detection port 34a and guided into the gas detector 30 to accurately detect the channel 3.

The liquid injection hole 4 is formed from the channel 3 of the mortar layer 1c detected by this method to the watertight layer 1b of the roof 1 toward the inside thereof.

The waterproof adhesive injection nozzle 40 is inserted into the liquid injection hole 4, and its front end reaches this waterproof layer inside.

The injection nozzle 40 is injected with a waterproof adhesive E containing a waterproof adhesive composed of a solvent volatilized emulsion zone and filled and cured in the entire channel 3 to completely close the leaked portion.

As described above, according to the present invention, the detection gas such as carbon dioxide gas is pumped to the outer wall surface 1c side from the inner wall surface 1a side where cracks, rises, and junks are generated, and the detection gas is blown to the gas detector 30. The invisible channel 3 is detected by the detection, and by the filling curing of the waterproof adhesive E containing the solvent volatile emulsion zone which is hardened by contacting air in the channel, a particularly excellent waterproof effect can be obtained.

At the same time, the waterway 3 is found quickly or accurately, and the repair work is completed only in the local area, and the construction is completed in a very short period of time without damaging the existing roof as it is.

In addition, the waterproof adhesive presses the waterproof adhesive E containing the solvent volatilization emulsion, so that even if the channel 3 is wet, injection penetration is possible and exhibits a high waterproof effect by its strong adhesive force.

In addition, since the ultrasonic oscillator 10 and the ultrasonic receiver 12 are formed on the inner wall surface of the roof wall or the like, respectively, and the working position thereof is approximately known, the leaking part is easy to find.

In addition, since the ultrasonic oscillator 10 and the detection gas generator 20 are formed indoors, the gas temperature, the pressure regulator 24, and the pressure valve 24a are also formed in the detection gas generator. In addition, it is safe and can detect and carry out the red-hot pressure detection gas in the channel 3.

On the mortar layer 1c of the concrete roof 1 to detect, the ultrasonic receiver 12 and the gas detector 30 are formed corresponding to the ultrasonic oscillator 10. FIG.

The gas detector 30 is connected to the base of the hose 34 having the detection port 34a at its front end, and the other end of the power cord 32 having the plug 32a formed at the front end thereof. An internal detection buzzer is built in the gas detector main body, and the digital display system 36 in which a switch (all are not shown) was formed in the surface required part is connected.
