コンクリート表面を侵食するためと考えられる。2. Description of the Related Art The surface of concrete such as a concrete sewage treatment tank is easily corroded, and in severe cases, it may be corroded enough to expose the reinforcing bars inside the concrete.
It is considered that the main cause is that hydrogen sulfide generated by anaerobic decomposition of organic matter in sewage dissolves in water to become strongly acidic sulfuric acid, and this sulfuric acid corrodes the concrete surface.

った。[0004] In order to prevent this, the anticorrosive sheet lining method of applying a primer to the surface of concrete and adhering the anticorrosive sheet has been conventionally used. However, this method has a problem that the anticorrosion sheet is apt to be peeled off from the concrete surface because the anticorrosion sheet has a weak fixing strength.

されていた。In order to deal with such a problem, a corrosion-resistant sheet lining construction method has recently been developed, in which a corrosion-resistant sheet having projections formed on one surface is nailed to the inner surface of the mold and concrete is placed inside the mold, which has attracted attention. It is growing. With this method, when the concrete hardens, the projections of the anticorrosion sheet stick firmly to the concrete surface in a state of biting into it, so if you remove the formwork and weld the seams of the anticorrosion sheet with resin, there is no risk of peeling. Although the sheet layer can be formed on the concrete surface, the following points to be improved still remain.

Since the anticorrosion sheet is temporarily fixed to the formwork with a nail, when the formwork is removed after the concrete is hardened, the nail penetrates the anticorrosion sheet and projects to the surface. Therefore, in addition to the welding work of the seam of the anticorrosion sheet, it is necessary to cut the protruding portion of the nail and cover and weld the punched holes one by one with the resin, which is a troublesome and time-consuming problem. Further, when the punching holes are coated and welded one by one with the resin as described above, some of them may leak the sewage or the chemical liquid due to defective welding, which is a problem in terms of reliability.

ることにある。The present invention has been made in view of the above problems, and it is an object of the present invention to temporarily fix an anticorrosive sheet to a mold without punching it with a nail, and even if there is a haunch portion, the shape is maintained. Another object of the present invention is to provide a lining construction method capable of temporarily fixing an anticorrosion sheet and having excellent workability and reliability.

る。In order to achieve the above-mentioned object, the method for lining a concrete surface of an anticorrosive sheet according to the present invention is such that the end of the anticorrosive sheet having a projection formed on one side is connected to both ends of a flexible connecting piece. While connecting the anticorrosion sheet by inserting it into the concave part, fix the center of the connection piece to the formwork with a stopper and temporarily fix the anticorrosion sheet to the inner surface of the formwork, and place concrete inside the formwork. It is a feature.

上する。As in the construction method of the present invention, when the anticorrosion sheet is connected through the connecting piece, the connecting piece is fixed to the frame by the stopper and the anticorrosive sheet is temporarily fixed, the connecting piece has a hole for the stopper. Although it is open, the anticorrosion sheet does not have holes. Therefore, the mold is removed after the concrete is hardened, the exposed part of the connecting piece exposed on the surface of the connecting part of the anticorrosion sheet is scraped off, and the stopper protruding from the connecting piece is cut to remove the connecting part of the anticorrosion sheet from the resin. Only by welding, it is possible to form a reliable anticorrosion sheet layer on the concrete surface, and the complicated work of coating the holes on the anticorrosion sheet with resin one by one as in the past, and sewage from poorly welded holes Since there is no risk of chemicals leaking out, the workability and reliability are greatly improved.

ことができる。Further, since the connecting piece used in the method of the present invention has a bendable center, even when the haunch portion is formed on the concrete surface, the anticorrosion sheet is bent at the connecting piece in the shape of the haunch portion. It can be temporarily fixed to the formwork.

As shown in FIG. 5, a large number of projections 3a are formed on one side of the sheet. It is formed in a staggered pattern. The protrusion 3a has a shape in which a pair of protrusions 31a, 31a inclined in directions away from each other are connected by an intermediate connecting piece 32a. For example, a T-shaped cross section, an arrow shape,
Any shape, such as a mushroom shape, whose tip does not swell out of concrete can be used. Further, instead of the staggered protrusions 3a, an anticorrosive sheet in which rib-like continuous protrusions are formed in parallel at regular intervals may be used.
