PROBLEM TO BE SOLVED: To provide a connection structure of storage and infiltration units capable of coping with a gentle bend. SOLUTION: The connection structure C of storage and infiltration units connect the storage and infiltration units 1, 1A for storing rainwater to infiltrate into the ground, to each other. A straight pipe 2 is connected to a sand collecting receiving frame 13A inserted in the lower part of one storage and infiltration unit 1A, and a flexible pipe 3 capable of changing a connection angle is connected to a sand collecting receiving frame 13 inserted in the lower part of the other storage and infiltration unit. The straight pipe 2 and the flexible pipe 3 are connected turnably in vertical and horizontal directions to attain connection at an angle gentler than 90°. COPYRIGHT: (C)2009,JPO&INPIT
