More particularly, the present invention relates to a composite waterproof structure and a method of constructing the same. More particularly, Which is capable of forming a watertight junction between the modified asphalt sheet and the liquid-phase coating material, and a method of constructing the composite waterproof structure.
The waterproofing method can be broadly divided into a sheet waterproofing method, a film waterproofing method, and a composite waterproofing method in which these are mixed. The sheet waterproofing method is a method of forming a waterproof layer by using an adhesive agent or fusing the factory-produced waterproof sheet. Since the product is standardized, the thickness of the waterproof layer is uniform, the finish is good, the construction is quick, The occurrence rate of defects is high at the joint portions between the sheets and it is difficult to work the complicated construction site and there is a possibility that the wall and parapet portions are peeled and sagged due to the temperature change after the construction. Further, since the sheet material is sensitive to temperature, it is influenced by work in the winter or summer season, and waterproof performance is deteriorated due to partial joining failure and insufficient stability.
In addition, the coating film waterproofing method is a method in which a waterproofing material is applied a plurality of times to a base surface to form a waterproof film. Since a waterproof layer is formed by simply transporting a material and applying a liquid state material, Although it is possible to easily perform construction even if it is applied to the base surface, there is a problem that the thickness of the coating film is unevenly formed along the irregularities of the base surface because the concrete base surface can not be raised irregularly even if the construction is well done. There is a problem in that a part of the waterproof membrane may be swollen due to the water vapor pressure generated on the concrete base surface or pinholes may be generated due to pores on the surface of the concrete and a phenomenon such as poor curing due to erroneous mixing of materials may occur have.

The waterproofing is directly connected to the water leakage even if any part of the waterproofing area is defective after construction. Especially, the part where the water leakage occurs is a joint part where the sheet and the sheet are connected to each other. However, in the combined waterproofing method, there is a problem that the sheet is dissolved by the organic solvent contained in the coating material, which causes defects such as a lack of waterproofing performance, as well as a leakage of the dissolved material through the cracked portion of the structure, Due to the lack of interlayer integrity between the two materials due to the use of different heterogeneous materials, the problem of breaking the joint between sheets due to delamination and lack of flexibility is still a problem, and adhesion at the interface The watertightness is rapidly deteriorated, and the sheet is repeatedly shrunk and expanded according to the outside air temperature, so that cracks or breakage of the joint portion coating film occurs and leakage occurs.

The sheet with three sand on the bottom of the waterproof sheet that has appeared so far has poor adhesion to the three sand and compound layers. Therefore, there are various problems. Firstly, since the waterproof sheet is stored and transported in a roll state, the three sands are not able to function because of the problem of falling off from the compound layer. Second, In addition, there is a problem in that a large amount of three sands are separated from the compound layer due to the impact due to the fact that the sheet is thrown during the time and the construction process. Third, the sheet is shrunk or expanded according to the outside temperature, There is a problem that three sands attached to the edge portion of the sheet can not withstand the tensile force due to deformation of the sheet and are detached from the compound layer. Fourth, the organic solvent contained in the polyurethane dissolves the compound of the sheet, There is a problem that three sands can not function.

Since the width of the waterproof sheet is usually 1 m, a bonding portion is formed every 1 m. The primer is applied to a portion where the edge of the waterproof sheet is to be positioned at a width of about 100 to 300 mm. The polyurethane applied on the primer layer has a width of 100 to 200 mm Lt; / RTI > When a reinforcing material is provided on the abutting portion between the sheet and the sheet and polyurethane is applied to the abutting portion between the sheet and the sheet, the polyurethane penetrates into the reinforcing material, which is glass fiber, And the two sheets are integrated with the coating film to form a stable joint, thereby ensuring the watertightness of the joint having the highest frequency of occurrence of defects.
Polyurethane may be applied to the entire upper surface of the sheet 1 to several times after the completion of the joint application, and silica sand may be sprayed simultaneously if necessary. The polyurethane used for the joint portion may be a general polyurethane, but it is preferable to use a water-hardened urethane or a water-soluble urethane. Such a water-hardened urethane or a water-soluble urethane can be produced by a process in which a compound layer of a waterproof sheet is dissolved in an organic solvent The breakage of the joint portion can be fundamentally prevented.
