Rainwater storage and infiltration facility
In order to solve the problems of maintaining the strength of a rainwater storage/infiltration facility or even reducing the number of unit members used in per unit area, the rainwater storage/infiltration facility is provided. Then, the void space ratio of a rainwater storage space is increased, and a plurality of inspection ports penetrating in the vertical direction are formed, thereby facilitating the inspection work of the rainwater storage/infiltration facility. Each measure unit member (A) for solving the problems comprises a square flat plate (31) with a given thickness and hollow legs(32 and 33) in a truncated circular cone shape, and the legs lead to contact surfaces (34) formed on the four corners and the flat plate (31). Each contact surface (34) is provided with an engagementprotrusion (321) and an engagement recess (331) for being interconnected with other unit members A. The engagement protrusions (321) of one unit member (A) and the engagement recesses (331) of another unit member (A) are placed facing each other to form a pair of unit members, and a given number of unit members are assembled in the horizontal and vertical directions to construct the rainwater storage/infiltration facility. Due to the fact that each contact surface (34) has a step thereon, a load can be supported by the steps on the two lateral sides of the contact surfaces. According to the rainwater storage/infiltration facility, in the case of decreasing the number of unit members used in per unit area to increase the void space ratio of the rainwater storage space, the strength of therainwater storage/infiltration facility is maintained, and a plurality of inspection ports penetrating in the vertical direction are formed to facilitate the inspection work of the rainwater storage/infiltration facility.
问题为了维持雨水蓄存/入渗设施的强度甚至通过减小每单位面积所使用的单元构件的数量，从而雨水蓄存空间的空隙空间比率增加，并且形成沿着竖直方向穿通的多个检查口，从而有助于雨水蓄存/入渗设施的检查工作。解决问题的措施单元构件(A)包括给定厚度的方形平板(31)和呈截台圆锥形的中空的腿(32、33)，腿通向在四个角部和平板(31)上形成的接触面(34)。接触面(34)设置有接合凸部321和接合凹部(331)，用于与其它单元构件A相互连接。将一个单元构件(A)的接合凸部(321)和另一单元构件(A)的接合凹部(331)放置成面向彼此以形成一对单元构件，并沿水平和竖直方向组装给定数量对的单元构件以构造雨水蓄存/入渗设施。因接触面(34)其上具有台阶，负载可借助接触面的两个侧向侧面的台阶支撑。解决了：在减少单位面积使用的单元构件的数量以增加雨水蓄存空间的空隙空间比率情况下，维持雨水蓄存/入渗设施的强度，以及形成沿竖直方向穿透的多个检查端口以方便雨水蓄存/入渗设施的检查工作。
