It is difficult to secure enough working space to do so, which makes the efficiency considerably less efficient. The storm storage tank constructed by the concrete casting method can be used to improve the storage efficiency by adopting the column and beam structure and to perform the soil discharge and cleaning operations relatively efficiently, but the air due to the construction of the storm storage tank There is a problem in that it interferes with the surrounding residents' lives and traffic flows during the work period, and it is disadvantageous for post-partial maintenance.

In order to cope with these problems, excellent storage tanks have been developed in which outer walls, columns, beams, slabs, etc. are manufactured as PC blocks (Precast Concrete Blocks) and assembled on site, thereby improving construction convenience and improving air quality. ), The maintenance, maintenance and partial maintenance can be done efficiently.
