へと変化してきている背景がある。これは、一般的に水
槽は地下に埋設するために穴を掘る作業を行なうが、こ
の穴堀作業の労力を最小限に抑え、より大容量の水槽を
埋設するために角形に近いものとするものである。However, in recent years, there is a background that the cross-sectional shape of the water tank has changed from a shape close to a perfect circle to a shape closer to a prism. This is generally done by digging holes for the water tank to be buried underground, but the work of this hole excavation work should be minimized and the water tank should be close to a square to bury a larger capacity water tank. It is a thing.

は、一体成形のものが使用できないという問題がある。
これは、アールのきつい部分が多いために製作が困難で
あり、取付作業もより精度を求められるためである。In the case of a shape close to a perfect circle, it is more convenient in terms of cost and labor to use an integrally formed reinforcing ring, but the sectional shape shown in FIG. 8 is closer to a square shape. The reinforcing ring used for the cylindrical pipe 1 having a shape cannot be integrally molded.
This is because it is difficult to manufacture because there are many rounded portions, and more accurate mounting work is required.
【０００６】本発明はこのような問題点に着目してなさ
れたもので、より角形に近い形状の円筒状パイプを使用
した水槽を提供することを目的とする。The present invention has been made in view of such problems, and an object thereof is to provide a water tank using a cylindrical pipe having a shape closer to a prismatic shape.

筒状パイプに設けられていることを特徴とする。In order to achieve the above object, according to the invention of claim 1, in a water tank in which both ends of a cylindrical pipe made of reinforced plastic are closed with end plates and a reinforcing ring is provided inside. The reinforcing ring has a bag-shaped portion where the reinforcing members divided into a plurality of parts are stuck together,
Characterized in that provided in the integrated bag-like portion fitted to an end portion of the reinforcing member said cylindrical pipe.

It can be increased and the installation work is easy. In addition, since the shape of the reinforcing material itself is deformed or the material is changed depending on the mounting position of the reinforcing material, the reinforcing material used in the lower part of the water tank, where the weight of the water tank is the highest, is made thicker than the reinforcing material used in other parts, It is possible to strengthen the entire water tank by using a stronger material.
As a matter of course, it is possible to further increase the strength by changing both the shape and the material.

Further, it is preferable that the end portion of the reinforcing material is provided with a cut portion for joining with another reinforcing material, or one end thereof has a bag shape. From the viewpoint of strength, this attachment is preferably fixed by bolts, overlay by FRP, or a composite connection thereof. The length of the portion where the reinforcing materials overlap each other can be appropriately selected, but is preferably 50 to 500 mm in view of the overall strength and cost.

Specifically, when the reinforcing ring is divided into three, a reinforcing material divided every 120 degrees is prepared, and only the reinforcing material used in the lower part of the water tank is made thicker or the material is made into another material.
It is preferable that the two reinforcements are different. The interval at which the reinforcing ring is provided in the water tank largely depends on the size of the entire water tank, but an interval of 0.5 to 3 pieces / m is suitable for maintaining the rigidity of the entire water tank.

構造となっている。EXAMPLE A water tank of the present invention will be described below with reference to FIGS. 1 to 3 and 9. FIG. 1 is a longitudinal cross-sectional view of the water tank of the present invention. The water tank 3 has a structure in which end plates 2 are joined to both ends of a cylindrical pipe 1 formed of reinforced plastic, and a reinforcing ring 5 is attached to the inner surface of the cylindrical pipe 1 in the circumferential direction.

上がるという効果も当然のことながら有している。Since the reinforcing ring is divided into a plurality of parts, even if a cylindrical pipe having a nearly rectangular shape as shown in FIG. 8 is used,
The reinforcement ring can be joined to increase the rigidity of the entire water tank, and the reinforcement material can be easily manufactured. Further, by sequentially mounting the reinforcing material on the inner surface of the cylindrical pipe, the mounting workability can be improved, and the reinforcing ring can be downsized as compared with the case where the reinforcing ring is formed as an integrally molded product, so that the transportation efficiency can be improved. Providing the laminated portion on the reinforcing material strengthens the reinforcing ring itself and also strengthens the water tank itself. When the reinforcing material is provided inside the cylindrical pipe, it naturally has an effect that the workability is improved when the reinforcing ring is divided into a plurality of pieces.
