OPEN SHIELD MACHINE, AND TUNNEL CONSTRUCTION METHOD
To provide an open shield machine applicable to construction of a tunnel with a large diameter.SOLUTION: An open shield machine 1 comprises: a box-shaped body part 2 having a bulkhead 10 at a front face 2a, a first opening 21 in an upper surface 2f and a second opening 22 in a lower part of a rear face 2b; a shield jack 7 arranged on the body part 2 so as to advance the body part 2 forward; an excavation machine 4 forming an excavation pit 30 in the natural ground G in front of the body part 2; and slurry discharging means 6 for discharging slurry in the excavation pit 30 out of the excavation pit 30. The slurry discharging means 6 includes a slurry discharging port 36 formed by penetrating into the bulkhead 10.SELECTED DRAWING: Figure 1
【課題】大口径のトンネルの構築に使用可能なオープンシールド機を提供する。【解決手段】オープンシールド機１は、前面２ａにバルクヘッド１０を有し、上面２ｆに第１開口部２１を有し、かつ、後面２ｂの下部に第２開口部２２を有する箱状の本体部２と、本体部２に設けられて本体部２を前方に推進する推進ジャッキ７と、本体部２より前方の地山Ｇに掘削溝３０を形成する掘削機４と、掘削溝３０内の泥水を掘削溝３０外に排出する泥水排出手段６と、を備える。泥水排出手段６は、バルクヘッド１０に貫通形成された泥水排出口３６を含む。【選択図】図１
