Title:
RAINWATER STORAGE TANK BLOCK AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2022094869
Kind Code:
A
Abstract:
To provide a simple block of a rainwater storage tank capable of reducing the price including the construction cost by solving problems in the conventional construction method in which large polypropylene blocks are stacked and the storage tank is buried, which is limited to some manufacturers having large injection equipment resulting in very high manufacturing cost and transportation cost.SOLUTION: A rainwater storage block is manufactured by tying easy-to-obtain synthetic resin cylindrical tubes together in units of three. With this, a rainwater storage tank block can be easily manufactured at a low price and can be widely supplied to wide users. A rainwater storage tank can be built by alternately installing and stacking multiple blocks of synthetic resin cylindrical tubes that are tightly connected in units of three.SELECTED DRAWING: Figure 1
