METHOD FOR CONSTRUCTING DRAIN DRAINAGE CHANNEL
PROBLEM TO BE SOLVED: To propose a method for constructing a drain drainage channel that makes it possible to form drainage channels and the like that do not require electric power and the like easily and reliably at the time of drainage.SOLUTION: The present invention includes a conduit forming step of forming a conduit 6 which does not penetrate a dam body 2 by excavating using an auger screw 4 and disposing a pipe member 5, a water stopping step of injecting a water stopping material 7 to a tip side of the conduit 6 to shield the conduit 6, a penetrating step of penetrating the dam body 2 through the conduit 6 by pushing a base end portion of the conduit 6, and a recovery step of recovering the auger screw 4. In the conduit forming step, after extending the conduit 6 by a predetermined length, the conduit 6 is extended while changing the auger screw 4 and the pipe member 5 to ones having a small diameter.SELECTED DRAWING: Figure 1
【課題】簡易かつ確実に、排水時に電力等を必要としない排水路等を形成することを可能とした水抜き排水路の施工方法を提案する。【解決手段】 オーガースクリュー4を用いて掘削するとともに管材5を配設することで堤体2を貫通しない管路6を形成する管路形成工程と、管路6の先端側に止水材7を注入して管路6を遮蔽する止水工程と、管路6の基端部を押し込むことで堤体2を管路6によって貫通する貫通工程と、オーガースクリュー4を回収する回収工程とを備えており、管路形成工程では、管路6を所定延長形成した後、オーガースクリュー4および管材5を小径のものに変更しながら管路6を延長する。【選択図】図1
