Description

Rainwater Storage Tank {Water storage tank}

The present invention relates to a rainwater storage tank, and more particularly, to a rainwater storage tank that can store the rainwater to discharge to the river to control the flow rate of rainwater.

As buildings increase and the surface pavement rate increases, rainwater does not flood into the basement during heavy rains. As such, when rainwater flows in at one time and exceeds the inflow allowance, flooding may occur.

On the contrary, if less rainwater flows into the river, the water quality of the groundwater is deteriorated and the groundwater is also depleted. In order to prevent this, in recent years, rainwater is stored in an excellent storage tank and discharged into a river to control the flow rate of rainwater.

As an example of the technique of this excellent storage tank, the excellent storage tank (patent No. 485742) and the excellent storage tank (patent registration number 582121) patented and registered by this applicant are mentioned.

First, Patent No. 485742 relates to an excellent storage tank and includes a main block, a peripheral block, and a slab. In the block for the main body, pillars are provided at right angles to each of four corners at the front, rear, left, and right sides of the top plate and the bottom plate. Through-holes formed on the inside are formed, respectively, and a plurality of grooves into which the couple guide pins are inserted are formed on the outer surface. The peripheral block has the same configuration as the block for the main body except that one or more of the four faces take a closed form. The slab is coupled to the peripheral block by screw members extending outward from the peripheral block so as to close the opening of the peripheral block facing outward when assembled.

Next, Patent No. 582121 relates to an excellent storage tank and includes a storage block and an upper block. In the storage block, pillars are formed at each corner of the top plate and the bottom plate such that openings are formed at sides of the hexahedron, and a plurality of nut set grooves are formed at the top and bottom of each pillar, and at least one side of the top plate A stepped portion is formed, and the bottom plate is formed with an engaging portion so as to be integral with the base surface. In addition, the upper block has a rectangular plate shape, the end of which is seated on the upper plate stepped portion of the storage block to form the same plane as the upper plate of the storage block. Here, the plurality of storage blocks are repeatedly arranged in a straight line, and the upper surface block is configured such that a plurality of the storage blocks are coupled between the storage blocks in a straight line to form a storage space.

Despite the other technical advantages such as easy construction, the shape of the main block of the rainwater storage tank of Patent No. 485742 and the storage block of the rainwater storage tank of Patent No. 582121 have the structure of a cube formed by the upper plate and the lower plate integrally formed by a column. Since the weight of the block itself becomes very large, it is very disadvantageous for transportation, and when the block is manufactured in advance and transported by the vehicle, the loading space of the vehicle is limited and the size of the block can be increased as desired. Can't.

In addition, when the main block and the storage block is manufactured in the form of a cube formed by the upper plate and the lower plate integrally formed by the pillar, the formwork must be manufactured in the form of a cube in order to form the block into concrete, and concrete is formed inside the formwork. The production is very cumbersome and inconvenient, as it takes a long time to cure.

In addition, when the volume of the body block and the storage block having a hexahedron shape increases and the weight thereof increases, it is very cumbersome and inconvenient to assemble the rainwater storage tank. For example, if the heavy body block and the storage block are not correctly positioned at the construction position, the crane must be repeatedly modified to position the body block and the storage block with the hexahedral structure correctly.

In addition, the main body block and the peripheral block each include a pillar, and when arranging them, the pillars of the blocks overlap to provide an unnecessarily thick pillar structure, and when the pillars overlap, the internal space of the storage tank is narrowed to clean before and after construction. And internal management becomes difficult.
