CLOSING PLUG FOR DRAIN PIPE
PROBLEM TO BE SOLVED: To provide a closing plug that prevents inflow of rainwater, sediment, drainage and others into a main sewer system, may be fitted readily to a public catch basin, and is suited not only to a horizontal-type, but also to a vertical-type catch basin.SOLUTION: A closing plug for a drain pipe includes a plug body 1a made of a bottomed tube, on which a pair of engaging holes 2a, 2a is formed on an outer peripheral part near an opening of the plug body 1a as fitting means for fitting the closing plug to a public catch basin. Also formed on the bottomed tube is a through-hole 3a for inserting a bolt or an engaging protrusion as fixing means, on an outer peripheral part near a bottom surface of the plug body 1a. The plug body 1a may be fitted on both horizontal-type and vertical-type public catch basins.SELECTED DRAWING: Figure 1
【課題】 下水本管へ雨水や土砂、排水等が流入することを阻止することができ、しかも公共マスへの装着が容易で、横型の排水マスのみならず縦型の排水マスにも装着することができる閉塞プラグを提供する。【解決手段】 有底の筒状体によってプラグ主体１ａを構成し、当該プラグ主体１ａの開口部近傍の外周部に一対の係合孔２ａ，２ａを設けて公共マスに装着するための取付手段とし、前記プラグ主体１ａの底面部近傍の外周部にボルト挿通用の透孔３ａもしくは係合突起を設けて固定手段としたもので、前記プラグ主体１ａは、横型もしくは縦型のいずれの公共マスにも装着することができる。【選択図】 図１
