Description

Inorganic permeability composite waterproofing method {METHOD FOR PREVENTING CONCRETE WALL FROM SEEPAGE BY USING INORGANIC PERMEABLE WATERPROOFING COMPOSITE}

The present invention relates to a method for waterproofing a leaky part of a wall of a structure made of concrete, cement, and other similar materials, and more specifically, to a leak freeze index on a leaked part, and using a spray gun. After applying the liquid permeable waterproofing agent, the structure wall surface is first converted into watertight waterproofing. Then, the color siliceous coating type waterproofing agent is applied twice in the desired color to penetrate into the structure wall surface and at the same time integrate the coating film to achieve excellent waterproofing performance. The present invention relates to an inorganic permeable composite waterproofing method capable of securing and preventing cracks and achieving a beautiful appearance.

In general, when the structure is a concrete wall, cracks occur due to poor conditions such as vibrations and shocks caused by seasonal differences in temperature and various external forces.

In particular, there are many cracks on the wall of the structure due to large seasonal differences in temperature, heavy rains and typhoons in Korea, and rainwater penetrates and damages buildings.

Therefore, there is a trend in the art to prevent rainwater from penetrating the structure, and at the same time, to develop a waterproofing and finishing method that can be integrated and appropriately cope with the behavior and cracking of the structure.

As such a conventional technique, a method of densifying a structure using a liquid permeable waterproofing agent and applying a cement paste on its outer surface has been proposed.

Such a conventional technique is shown step by step in FIG. 1, first pretreating the concrete base surface (10, where the base surface refers to the concrete wall surface. Repair (20) leaking parts such as cracks and joints on the concrete surface.

A liquid permeable waterproofing agent (such as one-component insoluble acrylic is used) is applied to the underside of the structure, the cement paste is first applied 40 thereon, and the cement paste is secondly applied thereon (50). ), Then finish the plastering by constructing a waterproof mortar (60).

However, the conventional method, such as the lack of stretching due to the properties of the cement paste material properties, due to the change in temperature and various loads do not adequately respond to the behavior and cracking of the structure and cracks occur.

Therefore, water penetrates through the cracks again, causing the cement paste layer to rise and causing corrosion of concrete structures and rebars.

In addition, since the conventional method utilizes the liquid permeable waterproofing agent 30 and the cement pastes 40 and 50 in the first and second stages, after the construction of the waterproof mortar 60, a beautiful color appearance is secured on the finishing surface. In order to complete the appearance by coating the color using a separate paint, such as to have a cumbersome disadvantage.

The present invention is to solve the conventional problems as described above, the purpose is to make the waterproofing coating film integrated with the structure to improve the followability to the crack and stretch of the wall surface of the structure caused by the change of temperature and various external forces crack and It is possible to prevent renovation due to breakage, and to provide inorganic waterproof composite waterproofing method to get a beautiful appearance at the same time as the finishing layer construction.

And another object of the present invention is to not only achieve a perfect waterproof effect, but also to minimize the cracks of the waterproof finish layer, to prevent re-repair, easy to be installed by the spray-type construction, after the separate painting step The present invention provides an inorganic permeable composite waterproofing method that can be expected to reduce costs by greatly reducing costs.

According to an aspect of the present invention,

A lower surface pretreatment step of the surface of the concrete structure in which the leaking site occurs;

A beginner's stop agent processing step of blocking the leak with the first stop's index agent;

Applying a liquid permeable waterproofing agent layer to the leaking part;

First applying a color siliceous-based coating type waterproofing agent prepared in a desired color on the liquid permeable waterproofing agent layer by mixing with water to meet the indicated blending ratio; And

The inorganic color permeable composite waterproofing method to exhibit a semi-permanent waterproof performance, and to secure a beautiful appearance, including the step of applying a second color siliceous-based coating type waterproofing agent on the first color siliceous-based coating type waterproofing agent layer in the same manner. To provide.

As described above, the present invention prevents the breakage and the corrosion of the super-fastener in the leaked area, and the liquid permeable waterproofing agent therein increases the strength and abrasion resistance of the concrete structure and at the same time converts it to watertight waterproofing. The three-color waterproofing system can be constructed in such a way that the color-coated siliceous coating type waterproofing agent is applied to prevent cracking. Thus, in the sense of using the liquid permeable waterproofing agent and the siliceous coating type waterproofing agent it is referred to as a composite waterproof.

The present invention preferably includes applying the liquid permeable waterproofing agent layer and applying the first and second color siliceous based coating type waterproofing agents using a spray gun, respectively, using a liquid permeable waterproofing agent and a color siliceous based system. It is to apply the coating type waterproofing agents. Therefore, in the present invention, since the construction of the spray-type method using a spray gun is made, the construction method is facilitated, and the air can be shortened significantly.

In addition, the present invention preferably the step of applying the liquid permeable waterproofing agent is to apply a liquid permeable waterproofing agent 0.1 ~ 0.3ℓ / ㎡ on the surface of the structure. Through this, the liquid permeable waterproofing agent makes the concrete structure itself dense and waterproof, and at the same time, it enhances the durability and strength of the structure, prevents damage by freezing and thawing, improves the acid resistance and chemical resistance of the surface, and the adhesion of the waterproof finish layer. Improve.

In the present invention, the first step of applying the color siliceous coating type waterproofing agent is to apply the color siliceous coating type waterproofing agent at 0.5 to 1.5 Kg / m 2 on the liquid permeable waterproofing agent. Therefore, since the color siliceous coating type waterproofing agent penetrates into the structure and the coating film is integrated with the structure, and the expansion coefficient is more than the same as that of the structure, there is almost no defect repair due to cracking, and cracks are generated due to freezing and melting. There is no In addition, since it exhibits a dense waterproof effect compared to the conventional method and wet surface construction, it is possible to shorten the drying time of the base surface, so that the air is greatly shortened and economical, and no additional painting work such as painting is required.

Also preferably, the second step of applying the color siliceous-based coating type waterproofing agent is to apply the color siliceous-based coating type waterproofing agent at 0.2 to 1.0 Kg / m 2 on the first color siliceous-based coating type waterproofing agent. The color siliceous coating type waterproofing agent applied through this structure prevents water or rainwater from penetrating into the structure, and is integrated with the structure. There is no defect repair, and the occurrence of cracks due to freezing and thawing is suppressed. In addition, it is possible to exhibit a beautiful appearance with the color of the waterproof finish itself, so that painting work using a separate paint is unnecessary.

According to the inorganic permeable composite waterproofing method according to the present invention to prevent the lifting and corrosion of the structure due to the leakage site by indexing the water leakage using the super-freeze index agent, and to increase the strength and wear resistance of the concrete structure by applying a liquid permeable waterproofing agent Simultaneously with water conversion and watertight waterproofing, a three-dimensional waterproofing system can be constructed by applying twice the color siliceous coating type waterproofing agent. Therefore, it is possible to realize perfect waterproof at the leaking part of the structure, to prevent the occurrence of cracks, to reduce the enormous cost loss due to the repair of the fault, and to be able to construct the wet surface.

As such, separate cement paste finishing and paint color finishing steps may be excluded as in the prior art, thereby ensuring construction efficiency and convenience of finishing.

In addition, according to the present invention, a spray gun (spray gun) can be used to facilitate the construction method can greatly shorten the air, and through the finish of the color siliceous-based coating type waterproofing agent, the paint of the user's desired color and finish separately It is economical because it can reduce the painting finish using the back.

In addition, according to the present invention, when the behavior and cracking of the structure due to the seasonal temperature difference and various external forces, which are the biggest problems of the conventional infiltration waterproofing, the cement paste waterproofing finish layer has almost no elasticity coefficient, so cracking is insufficient due to lack of followability. In addition, water penetrates into the gaps, thereby reinforcing the reinforcing steel and concrete and lifting the waterproof layer. That is, the present invention forms a waterproof finish layer with a color siliceous-based coating type waterproofing agent to infiltrate the structure and at the same time, the coating film is integrated with the structure. Excellent effect of suppressing the occurrence of cracks due to freeze-thawing.

Hereinafter, a preferred embodiment by each working step in the inorganic permeable composite waterproofing method of the present invention will be described in detail with reference to the drawings.

Figure 2 is a flow chart showing a preferred embodiment for the inorganic permeable composite waterproofing method of the present invention, Figure 3 is a structure wall surface using a super-freeze index agent, a liquid permeable waterproofing agent and a color siliceous coating type waterproofing agent in accordance with the present invention It is a process step diagram which shows the construction procedure of the inorganic permeable composite waterproofing method to be installed in.

Inorganic permeable composite waterproofing method 100 according to the present invention is lifted and corrosion due to the leaking site through the index through the first stop index (120, for example, CX1, PLUG can be used) in the leaking site of the structure 110 Prevent,

After the application of the liquid permeable waterproofing agent 130 greatly improves the physical properties of the concrete structure 110, and first water-tight waterproof,

It is a method of providing a superior three-dimensional waterproof effect by finishing with a color siliceous-based coating type waterproofing agent 140, 150 over the first and second.

Inorganic permeable composite waterproofing method 100 of the present invention is a construction and civil structure 110 having a surface of concrete, cement and other similar materials specified by the design drawings, in particular underground internal and external walls and water purification plant, sewage requiring excellent waterproof effect It is a composite waterproofing method that can be variously applied to treatment plants.

Inorganic permeability composite waterproofing method 100 according to the present invention, as shown in steps 2 and 3, first, the concrete base surface pretreatment step to remove the foreign matter and clean the surface of the structure 110, the surface of the leak occurred ( S10) is made.

This concrete base surface pretreatment step (S10) is completely foreign matter that can be peeled off the waterproof layer, such as dust, latency, formwork remover, oil, paint attached to the base surface of the structure 110 having the leaked portion 105 is completely Remove

In particular, the protrusions on the wall of the structure 110 are removed by using a grinder, and the indentations, weak areas, and excited parts are thoroughly checked in advance so that the width and depth are at least 2 cm to clean the surface. Trim it, seal it with a repair mortar, and repair it to make it flat.

Through such a pretreatment step, it is possible to improve the adhesion to the waterproof coating by strengthening the bottom surface of the structure 110 and to improve the durability of the structure 110.

Accordingly, the concrete base surface pretreatment step (S10) completely removes the incomplete mortar layer and the foreign matter adsorbed on the wall construction surface of the structure 110, honeycomb (Crack), Cold Joints, Form Tie Holes, Necks, and Lines are thoroughly checked and chipped, drilled, and repaired so that their width and depth are at least 2 cm.

Then, when the base surface pretreatment step S10 of the structure is completed as described above, as shown in S20 of FIG. 2, the leak-stopping portion 105 of the base surface of the structure may be used as a beginner index agent 120 (eg, CX1, PLUG). The elementary settlement index stage is performed to prevent leakage by repairing to.

In this case, when the leakage occurs in the wall or the floor of the concrete or the masonry structure 110, the initial stop index is immediately determined in the state of leakage. If there is a local part where leakage occurs by the method that can be indexed using (120), it is performed.

At this time, the area to be leaked is cut to a depth or width of 2 cm or more, V or U shape, and the surface is cleanly finished to sufficiently prepare the index. In such a step (S20), the prepared super-freeze index agent 120 is put in a container as necessary, for example, when the size of the V-cut groove is 2 cm x 2 cm x 1 m, the container is 0.6-0.7 Kg. Knead by adding about 30% of clean water in the volume ratio, and press with a hand or a tool to fill the cut surface when exothermic drying begins.

Simultaneously with the start of curing of the superconstant index agent 120, water should be sprayed on the construction site so as not to dry for about 10 minutes to aid in curing. However, when the construction surface or the air temperature is low, the curing speed can be shortened by using hot water, and the mixing amount should be adjusted in consideration of the short curing time when mixing the materials.

Therefore, if the leakage occurs in the wall and the floor of the concrete structure structure 110, the super fast index index step (S20) for the construction surface surface leakage site 105, the quick index index that can be immediately indexed in the state of leakage By using the super fastener index 120, it is possible to block the leakage within 1 to 3 minutes, to maintain a hard state without shrinkage, high strength within a short time after construction and the advantage of easy use is obtained.

Next, a step (S30) of applying a liquid permeable waterproof agent 130 layer using a spray gun on the wall surface of the structure 110 is performed.

The step of applying the liquid permeable waterproofing agent 130 layer (S30) forms a dense structure of the concrete structure 110 itself by using a copolymerized synthetic resin emulsion and a non-toxic resin-based permeable waterproofing agent composed of a plurality of active compounds. At the same time, waterproofing, and the durability and strength of the structure 110, preventing damage due to freezing and thawing, surface acid resistance, chemical resistance enhancement, and exhibits the functions and performance, such as improved adhesion of the waterproof finish layer.

When the liquid permeable waterproof agent 130 is used, the liquid permeable waterproof agent 130 is sprayed onto the surface cleanly cleaned by the pretreatment step S10 of the concrete structure 110 to 0.1 by a spray gun 160. Spray it at the amount of ~ 0.3ℓ / ㎡ and install it with the thickness of 0.03 ~ 0.1mm or less.

Liquid-permeable waterproofing agent 130 is an aqueous solution, there is no addition of water. At this time, the process of applying the liquid permeable waterproofing agent 130 using a spray gun (160) is as follows.

That is, as shown in FIG. 4, the liquid permeable waterproof agent 130 mixed with water is introduced into the material inlet 162 of the spray gun 160, and the liquid permeable waterproof agent is pressed by pressing the material inlet handle 166. When the air opening and closing handle 168 is opened while the 130 is inserted into the opening hole 167 of the lower side, the liquid-permeable waterproof agent 130 mixed with the water contained in the material storage container 170 is sprayed by the injection hole 172. Liquid permeation waterproofing is performed while spraying through the nozzle 174.

Then, after the step of applying the liquid permeable waterproofing agent 130 layer (S30), using a spray gun (Spray Gun) 160 on the liquid permeable waterproofing agent 130 layer, the color silicic acid-based coating prepared in a desired color Type waterproofing agent (140, which is applied to the surface of concrete to change concrete itself so that it has high waterproofness against high pressure permeability. The powder part is mainly composed of cement and granular silicate and siliceous fine powder. And a predetermined amount of water or a dedicated polymer dispersant is used in a beam; and mixed with water so as to meet the indicated blending ratio (S40).

The liquid-permeable waterproofing agent 130 applied in the step of applying the liquid-permeable waterproofing agent 130 layer (S30) has to be separated by waterproofing, chemical resistance, finish, etc. only by application of the stock solution, so that a separate waterproof finishing layer should be constructed. In the inorganic permeable composite waterproofing method 100 of the present invention by applying the color silicic acid-based coating type waterproofing agent 140, 150 two times to enhance the performance of waterproofing, and at the same time without the separate painting and finishing work and finishing effect Exert.

That is, the step of applying the liquid permeable waterproofing agent 130 layer (S30) is followed by the first step of applying the color siliceous-based coating type waterproofing agent 140 using a spray gun 160 (S40). It is constructed, after 1 day of construction of the step of applying the liquid permeable waterproofing agent (130) layer (S30).

At this time, after coating the conventional liquid permeable waterproofing agent 30 by applying the color silicic acid-based coating type waterproofing agent 140, the cement paste primary coating 40, the cement paste secondary coating 50, and the waterproof mortar 60 are constructed. In the process of finishing and finishing, the biggest problem is that the expansion coefficient of the cement material is less, it is possible to prevent the cracking and lifting occurring during the behavior and cracking of the structure.

Such a color siliceous coating type waterproofing agent 140 penetrates into the structure 110 and at the same time the coating film is integrated with the structure 110, and the defective repair due to cracking because the expansion coefficient is exhibited the same or more than the structure 110. There is little and there is no occurrence of cracking due to freeze thawing. In addition, as compared with the conventional method, it exhibits a more dense waterproof effect and wet surface construction, which can shorten the drying time of the base surface, thereby greatly reducing the air, and economical, and by using a coating agent of a user's desired color to separate paint, etc. No painting work required.

At this time, the coating method using the spray gun 160 is the same as the coating method of the liquid permeable waterproofing agent 130, and instead of the liquid permeable waterproofing agent 130, a color siliceous-based coating type waterproofing agent 140 is added thereto. Apply.

The color siliceous coating type waterproofing agent 140 used herein is placed in a mixing container with water at an accurate ratio of 25: 6.5-7 L, and is sufficiently used until the mass disappears using an electric low speed mixer (400-600 rpm). Stir. The agitated color siliceous-based coating type waterproofing agent 140 is introduced into the material inlet 162 and the horizontal direction or the vertical direction is set on the base surface of the structure 110 and applied in a predetermined direction, that is, 0.5 to 1.5 Kg /. M2 is first applied as a brush or spray and cured for at least 24 hours.

In this case, when the color siliceous coating type waterproofing agent 140 is less than 0.5 Kg / m 2, an appropriate waterproof layer cannot be formed, and if the color siliceous coating type waterproofing agent 140 is 1.5 Kg / m 2 or more, it is excessively undesirable. .

In this way, the second step of applying the color siliceous-based coating type waterproofing agent 140 to the first color siliceous-based coating type waterproofing agent 140 is performed in the same manner on the layer of the first color siliceous-based coating type waterproofing agent 140. Applying step 150 is made (S50).

That is, after the first application of the color siliceous-based coating type waterproofing agent 140 in the step of applying the color siliceous-based coating type waterproofing agent 140 at least 24 hours and curing is completed, 0.2 ~ 1.0 Kg / ㎡ The color siliceous-based coating type waterproofing agent 150 is secondly applied in the opposite direction as in the first application with the amount of.

At this time, if the color siliceous coating type waterproofing agent 150 is less than 0.2 Kg / m 2, an appropriate waterproof layer cannot be formed, and if the color siliceous coating type waterproofing agent 150 is 1.0 Kg / m 2 or more, it is excessively undesirable. .

In this case, the use of the color siliceous coating type waterproofing agent 150 is performed after the structure 110 is wetted with water so as to remain sufficiently moist, and when the temperature is 4.4 ° C. or lower or there is a risk of dropping to 4.4 ° C. or lower within 24 hours. It is forbidden to construct, and it is difficult to circulate air during curing, and it is a closed place, and the construction site with a lot of moisture in the air makes a drying and complete curing condition using a ventilator.

As described above, the inorganic permeable composite waterproofing method 100 according to the present invention is waterproofed with cement paste when behavior and cracking of the structure 110 occur due to a difference in seasonal temperature and various external forces, which are the biggest problems of the conventional waterproofing. Since the finishing layer has almost no elasticity coefficient, it is possible to effectively improve the lack of follow-up, cracking, water penetration into the gaps, corrosion of reinforcing steel and concrete, and lifting of the waterproof layer.

That is, by applying the color siliceous-based coating type waterproofing agent 140, 150 twice over the liquid permeable waterproofing agent 130 to form a waterproof finish layer, while preventing moisture or rainwater from penetrating into the structure 110, It is integrated with the structure 110, and the expansion coefficient exhibits the same performance as the structure 110 due to the properties of the structure 110, there is no defect repair due to cracks and the occurrence of cracks due to freezing and melting is suppressed.

In addition, it is possible to exhibit a beautiful appearance in the color of the waterproofing finish itself so that the core effect of the present invention that the painting work using a separate paint or the like is unnecessary.

As described above, when the leaking part 105 of the structure 110 is constructed through the inorganic permeable composite waterproofing method 100 of the present invention, as shown in cross section in FIG. A layer of water repellent agent 120 is formed, and a liquid permeable waterproofing agent 130 layer is formed thereon, and the first color siliceous coating type waterproofing agent 140 layer and the second color siliceous coating type waterproofing agent 150 layer are formed in turn. It is formed in turn.

Therefore, through the index of the leaking portion 105 through the super-freeze index agent 120 to prevent the lifting and corrosion of the structure 110 and by greatly improving the physical properties of the concrete structure 110 by applying the liquid permeable waterproofing agent 130 After the first water-tight waterproofing, the three-dimensional excellent waterproofing effect is obtained by applying and finishing the color siliceous-based coating type waterproofing agent 140 and 150 twice.

That is, by using the super-freeze index agent 120, the liquid permeable waterproofing agent 130 and the color siliceous-based coating type waterproofing agent (140, 150) to bring a perfect waterproof effect by waterproofing the wall surface of the structure (110), Minimization of cracks in the finishing layer can prevent refurbishment, and the spray-type construction method using a spray gun provides the advantages of easy construction.

In addition, the inorganic permeable composite waterproofing method 100 according to the present invention increases the strength and abrasion resistance of the concrete structure 110 by applying the liquid permeable waterproofing agent 130 compared with the prior art and at the same time after the first conversion to watertight waterproofing , Color silicic acid-based coating type waterproofing agent (140, 150) two times to build a three-dimensional waterproof system to achieve a perfect waterproof, prevent the occurrence of cracks to reduce enormous cost loss due to defect repair, wet surface construction This effect is excellent in that it is possible and the air is greatly shortened by an easy construction method using a spray gun.
