摘要

PURPOSE: To obtain an inexpensive and depth-adjustable infiltration inlet made of a synthetic resin. ;CONSTITUTION: A connecting cylinder 6 being opened in an inlet body 1 downwards and having a large diameter as much as possible is extended integrally to an infiltration inlet body l, in which a socket 2 for an inspection cylinder, with which the covered inspection cylinder 16 is joined, is mounted upwards and a plurality of sockets 3, 4 for manifolds, with which the manifolds for rainwater are joined, sideways respectively and which is made of a synthetic resin, and an infiltration inlet section 9 with a porous bottom section is connected detachably to the connecting cylinder 6, thus replacing the inlet body 1 with the infiltration inlet section 9 having different depth as it is. Accordingly, the inlet body 1 can be manufactured at a low cost by the merit of mass production, and the depth of the infiltration inlet section 9 can be adjusted.;COPYRIGHT: (C)1995,JPO
