Since rainwater is discharged from the surface of roads and other structures rapidly without any stagnation, the amount of rainwater flowing into the underground is remarkably large, because it is formed by materials having no permeability such as concrete or synthetic resin, . This phenomenon causes depletion of groundwater and causes water shortage. In addition, flood damage occurs even in low areas with low rainfall due to rapid movement to relatively low rainfall areas.

In order to prevent water shortage and flood damage, storm reservoirs are widely used. The storm reservoir is a structure that prevents the flooding of rivers and ensures the water resources that can be used for agricultural and cleaning purposes by releasing a large amount of rainwater drained and gradually discharging it. However, the conventional stormwater storage tank is a form of a large water tank using concrete, or a large water tank is formed by connecting blocks manufactured through a synthetic resin, so that it takes a long time to construct and it takes a lot of cost . Also, it is difficult to cope with the shape of the construction site appropriately, and the workability is not good, and the concrete structure has a short life span of 20 years or less, which leads to a significant economic burden.

In order to overcome the disadvantages of such a concrete stormwater storage tank, a stormwater storm tank has recently been developed. Corrugated steel pipes are generally used for drainage of sewage and wastewater, water for domestic or industrial use in the civil engineering field, and used as hollow formwork in the construction field. In recent years, there has been a lot of interest in manpower, cost, and environmental problems in the construction of drain pipes, so that corrugated steel pipes are widely used as substitutes for existing concrete re-pipes, and pipes having excellent external strength, structural stability, durability, It is attracting attention as material.

In addition, since the corrugated steel pipe is uniformly distributed in the pipe circumference, the corrugated steel pipe is used in waterways, passageways and other various structures with a large load-bearing capacity, and is easy to handle with light weight. Thus, both assembly and construction are simple and economical. The use of the coated steel sheet is advantageous in that it is resistant to corrosion and has a long life span.

Korean Patent No. 10-1481446 discloses a technique that utilizes the advantages of such a corrugated steel pipe in an excellent storage tank.

The stormwater storage tank includes a cylindrical corrugated steel pipe formed by winding a corrugated steel plate in a spiral shape, and a barrier plate having a curved surface contacting the inner surface at both ends of the corrugated steel pipe.

However, in the above-mentioned storeroom tank, the clogging plate is welded to both ends of the corrugated steel pipe. However, since the corrugated steel pipe has a curved cross section in its waveform, it can not be easily welded and fine gaps can be formed on the welded portion.
