Description

Injection device of waterproof agent

The present invention is installed on the surface of the structure to form a waterproof layer, the inner cover to form a predetermined space on the structure surface and the end is in close contact with the structure surface; An outer cover which surrounds the inner cover and maintains a predetermined distance from the inner cover, and the end cover is installed in close contact with the structure surface; An air discharge pipe inserted into the outer cover through the outer cover and capable of discharging air between the inner cover and the outer cover; And, through the inner cover and the outer cover is inserted into the inner cover, the waterproofing spray pipe capable of ejecting the waterproofing agent; It is for a waterproofing coating device characterized in that made of.

One of the factors that lowers the durability of reinforced concrete structures is water leakage due to the cracking of concrete. This leakage causes corrosion of the reinforcing bars, which in turn leads to an increase in the volume of the reinforcing bars, thereby increasing the crack width of the concrete.

In particular, concrete structures located underground are exposed to groundwater or wastewater, and salt or sulfuric acid contained in them causes corrosion of the concrete itself. When corrosion occurs in the concrete, the structure starts to break down from the skin, and if the corrosion progresses to a considerable extent, the concrete mass is not only dropped but also leads to corrosion of the reinforcing bars. Therefore, leakage occurs in the structure, and the life of the structure is reduced.

As a method for protecting concrete structures from water leakage due to cracking and corrosion of concrete, waterproof and anticorrosive construction can be considered to increase the watertightness of the structures. Waterproofing and anticorrosive construction are strictly different from each other, but they all have the same concept in that they are designed to protect the surface of the structure to minimize the influence of moisture or sulfuric acid, so it will be collectively described as waterproofing.

In the conventional waterproof construction of concrete structures, a method of forming a waterproof layer on the surface of a structure by using a brush, roller coating, spraying, or sheet waterproofing is used.

However, the waterproofing method using a brush or roller coating penetrates the waterproofing agent component to the structure side using only the absorbency of concrete under atmospheric pressure, so the penetration layer of the waterproofing agent is thin. Therefore, there is a disadvantage in that the waterproof layer is easily lost due to external impact or crack of concrete.

In addition, the waterproof method by spraying has the disadvantage that the waterproof film is irregularly formed when bubbles or pinholes are present on the concrete surface. Therefore, in order to form a uniform waterproof film, a process of forming a base adjustment layer as shown in FIG. 1 is required, thereby increasing air and construction costs. This method also has a drawback that the waterproofing layer is formed only on the surface of the structure because it sprays the waterproofing agent at atmospheric pressure.

In addition, the sheet waterproofing method may cause the structure and the waterproof sheet to separate over time due to the deterioration of the material.

The object of the present invention created to solve the above problems is as follows.

First, to provide a waterproof coating device that can form a thick waterproof layer to be integrated with the concrete structure, so that the waterproof layer is not damaged by external impact or cracks in the concrete.

Second, since the high pressure waterproofing agent penetrates deeply into the concrete voids, it provides a waterproofing coating device that can reduce air and construction costs by eliminating the process of preventing the construction of the ground adjustment layer or the lifting of the waterproofing layer and the crack repair process of the concrete. I would like to.

Third, it is possible to form a dense waterproof layer as long as it is in close contact with the concrete structure, to provide a waterproofing agent coating device that does not need to raise the waterproof layer in a special portion such as corners or protrusions.

In order to solve the above problems, the present invention is to be installed on the surface of the structure to form a waterproof layer, the inner cover to form a predetermined space on the surface of the structure is installed close to the surface of the structure; An outer cover which surrounds the inner cover and maintains a predetermined distance from the inner cover, and the end cover is installed in close contact with the structure surface; An air discharge pipe inserted into the outer cover through the outer cover and capable of discharging air between the inner cover and the outer cover; And a waterproof spray pipe which is inserted into the inner cover through the inner cover and the outer cover and is capable of ejecting the waterproof agent. It provides a waterproofing coating device, characterized in that consisting of.

That is, in the case of using the present invention, the waterproofing agent in a high pressure state penetrates into the concrete voids or cracks, thereby forming a dense waterproofing layer.

According to the present invention as described above is expected the following effects.

First, when the waterproofing agent is applied using the present invention, the waterproofing agent is penetrated under high pressure to form a thick waterproof layer integrated with the concrete structure, thereby preventing damage to the waterproofing layer due to external impact or cracking of the concrete.

Second, in the case of applying the waterproofing agent using the present invention, the high pressure waterproofing agent penetrates deeply into the concrete void, so that the construction of the base adjustment layer or the step of preventing the lifting of the waterproofing layer and the crack repair process of the concrete are unnecessary. And construction cost can be reduced.

Third, the waterproofing agent coating device of the present invention can evenly spray the waterproofing agent on the surface of the structure, it is not necessary to raise the waterproofing layer in special areas such as corners or protrusions.
