FORMING METHOD OF ADIT, AND ADIT
To provide an adit which does not require excavation of an arrival shaft by pulling an excavation machine back to a start shaft through an inside of a sheath pipe, which reduces a construction period and a construction cost, and in which an adit for discharging water can be laid to be provided underground in a short period of time.SOLUTION: In a method of embedding a water permeable drain pipe 31 underground from a start shaft 11 toward an arrival target position 12: a head of an excavation machine is inserted to be disposed so that a sediment shutter 40 provided at a head portion of a first sheath pipe becomes open; a connection sheath pipe is formed by sequentially connecting unit sheath pipes to move forward; the excavation machine is pulled back in a direction of the start shaft 11 and the sediment shutter 40 becomes closed; unit drain pipes are sequentially connected to a first drain pipe 31a1 in the connection sheath pipe to be inserted to the front side of the sediment shutter 40; a head portion 21a0 of the first sheath pipe is separated; the connection sheath pipe is pulled out in the direction of the start shaft 11 and broken down to the unit sheath pipes; and the head portion provided with the sediment shutter 40 and a connection drain pipe are embedded.SELECTED DRAWING: Figure 13
【課題】鞘管の内部を通して掘進機を発進立坑に引き戻すことで到達立坑の掘削は必要とせず、工期の短縮や工事費の削減につながり、地中に排水用の横抗を短期間で布設することができる横坑の提供。【解決手段】発進立坑１１から到達目標地点１２へ向けて地中内に透水性のドレイン管３１を埋設する方法であって、第１鞘管の先頭部に設けられた土砂シャッター４０を開とするように掘進機の頭を挿入して配置し、単位鞘管を順次連結し推進して連結鞘管を形成し、その後、掘進機を発進立抗１１方向へ引き戻すとともに土砂シャッター４０を閉の状態にし、次に、連結鞘管内に、第１ドレイン管３１ａ１に単位ドレイン管を順次連結して、土砂シャッター４０の手前まで挿入し、第１鞘管の先頭部２１ａ０を切り離して、連結鞘管を発進立抗１１方向へ引き抜くとともに単位鞘管に分解し、土砂シャッター４０を設けた先頭部及び連結ドレイン管を埋設する。【選択図】図１３
