重く、運搬、設置工事等の作業が困難であった。2. Description of the Related Art Conventionally, double-shell tanks have been manufactured from steel plates to have double inner and outer tanks. However, when the steel double shell tank comes into contact with soil, the outer shell tank is easily corroded, and therefore the outer surface of the outer shell tank is coated with tar epoxy resin or the like. Further, the steel double-shell tank has a heavy weight as a whole, which makes it difficult to carry it, carry out installation work and the like.

より成型していたのである。Therefore, by making the outer shell tank made of FRP, it was possible to prevent corrosion, to reduce the weight, and to improve the work safety. The structure of the double-shell tank whose outer shell tank is made of FRP has a steel inner shell of the underground tank body, a detection layer (hollow layer) for detecting oil leakage from the inner shell, and an outer shell F.
It consists of an outer tank made of RP. The outer shell tank can be molded by spray-up method, hand lay-up method, sheet molding method, filament winding method, etc., but conventionally, the outer shell tank was molded by any one of the above methods. .

ことを特徴とするものである。In order to solve the above-mentioned problems, the present invention is directed to forming a rising pipe portion and a manhole portion of a vapor phase portion of an FRP outer shell tank by a hand lay-up method, and It is characterized in that the above-mentioned part is formed by a spray-up method and the end plate part is formed by a sheet forming method.

が容易で早い。The operation of the present invention will be described. With the vicinity of the upper limit of oil storage in the tank as a boundary, the oil is not accumulated and rises above it, and the gas phase portion in which a pipe, a manhole or the like is present, and the oil accumulation Although it is divided into a lower liquid phase portion, the present invention requires that the liquid phase portion of the outer shell tank has a sensing layer having a void for detecting oil leakage between the inner shell tank and the outer shell tank. Therefore, since the resin must be bonded after the resin film is interposed in the inner shell tank, the spray-up method makes it possible to bond the resin evenly and the work is easy and quick.
【０００７】又、外殻タンクの気相部は検知層を必要と

ある。Further, the gas phase portion of the outer shell tank does not require a detection layer and is directly resin-bonded to the steel plate surface of the inner shell tank, but the gas phase portion is difficult to be formed by a spray-up method such as rising pipes or manholes. Therefore, according to the Handley-up method, resin bonding can be easily performed while avoiding these locations.

定するから正確な空隙形成が容易にできるものである。Further, the left and right end plate portions of the outer shell tank require a detection layer, but the resin film for forming voids cannot be evenly attached to the mirror surface. Therefore, according to the sheet forming method, Since a preformed FRP mirror plate is fixed according to a curved surface, accurate void formation can be easily performed.
