CONSTRUCTION METHOD OF WATER PASSAGE, AND JACKING MACHINE
PROBLEM TO BE SOLVED: To provide a construction method of a water passage that enables a drainage and other channels to be formed that does not require electricity, by forming an underground water passage, and a jacking machine used in the water passage construction.SOLUTION: A construction method of a water passage includes: a pipeline formation step in which pipeline 11 penetrating through a natural dam 2 is formed by a jacking method; a pipeline closing step in which a pipe plug 5 is formed for closing an end of the pipeline 11 on a pit face side; a jacking machine separation step in which a jacking machine 4 is separated from the pipeline 11 that has been closed; a jacking machine recovery step in which the separated jacking machine 4 is recovered; and a pipeline opening step in which the pipe plug 5 is removed. In the jacking machine separation step, the jacking machine 4 is made to float in water after being separated from the pipeline 11, using a floating body 44 fitted on the jacking machine 4.SELECTED DRAWING: Figure 4
【課題】地中に通水路を形成することで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通水路の施工方法および通水路の施工に使用する推進機を提案する。【解決手段】天然ダム２を貫通する管路１１を推進工法により形成する管路形成工程と、管路１１の切羽側端部を閉塞する管栓５を形成する管路閉塞工程と、閉塞された管路１１から推進機４を分離する推進機分離工程と、分離された推進機４を回収する推進機回収工程と、管栓５を撤去する管路開放工程とを備え、推進機分離工程では、推進機４に装着された浮体４４を利用して管路１１から分離した推進機４を水に浮かせる。【選択図】図４
