TEMPORARY FIXING PIN OF PERFORATED PIPE AND METHOD OF CONSTRUCTING MULTI-STAGE DRAIN PIPE USING THE SAME
PROBLEM TO BE SOLVED: To provide a temporary fixing pin for perforated pipes which can collectively arrange a plurality of perforated pipes having different pipe diameters without requiring packaging and the like, is free from anxiety about load collapse at the time of transportation, and is easy to be attached and detached.SOLUTION: In the state that all pipes of a plurality of perforated pipes having different pipe diameters are inserted into a pipe having the maximum diameter, a temporary fixing pin 1 of a removable perforated pipe which temporarily fixes the sliding movement of the plurality of perforated pipes by being inserted into holes of all the pipes of the plurality of perforated pipes includes: a grip portion 2 gripped and grasped during insertion and removal; and a leg portion 3 connected to the grip portion 2 and having one end folded back. The leg portion 3 is provided with: a linear guide portion 30 which is provided at a tip not connected to the grip portion 2 and serves as a guide when passing through the holes of the respective pipes of the plurality of perforated pipes; an engaging portion 31 connected to the guide portion 30 and engaged with the hole of the pipe of any of the plurality of perforated pipes; and a linear temporary fixing portion 32 connected to the engaging portion 31 and having a length inserted through all the pipes of the plurality of perforated pipes.SELECTED DRAWING: Figure 5
【課題】梱包等の必要がなく管径の異なる複数の有孔管を一纏めにすることができ、運搬時の荷崩れの心配がなく、且つ、着脱が容易な有孔管の仮固定ピンを提供する。【解決手段】管径の異なる複数の有孔管の全ての管を最大径の管内に挿入した状態で、前記複数の有孔管の全ての管の孔に挿通されることで前記復数の有孔管同士のスライド移動を一時的に仮固定する挿抜自在の有孔管の仮固定ピン１において、挿抜の際に把持して掴む把持部２と、把持部２と接続してその一端が折り返された脚部３と、を具備し、脚部３には、把持部２と接続しない先端に設けられて前記複数の有孔管の各管の孔に挿通する際のガイドとなる直線状のガイド部３０と、ガイド部３０と接続して前記複数の有孔管のいずれかの管の前記孔に係止される係止部３１と、係止部３１と接続して前記複数の有孔管の全ての管に亘って挿通される長さを有する直線状の仮固定部３２と、を設ける。【選択図】図５
