セミシールドの英語

推進工法においてトンネル施工の終点でセミシールド装置と推進管との切り離しを容易にすること。例文帳に追加

To facilitate separation of a semi-shield machine from a jacking pipe at a terminal point of tunneling work in a pipe jacking method. - 特許庁

次に推進ジャッキ３Ｃを除去して発進立坑１に設置の元押しジャッキ装置４で、仮設管３Ｂからセミシールド機３Ａを縮径状態で押圧掘進する。例文帳に追加

Then, the propulsion jack 3C is removed, and the semi-shield machine 3A is pushed forward for excavation, with its diameter being contracted, from the temporary laying pipe 3B by operation of a primary jacking device 4 installed at the starting shaft 1. - 特許庁

掘削土砂に優れた塑性流動性や止水性を付与するとともに、離水を充分に抑制し、掘削効率を充分に向上することができる泥土圧シールド工法及び土圧式セミシールド工法、並びに、該工法等の土木工法に好適に用いられる加泥剤を提供する。例文帳に追加

To provide a muddy earth pressure shield tunneling method and an earth pressure semi shield tunneling method imparting excellent plastic fluidity, water-stopping property to the excavated soil and sand and sufficiently suppressing syneresis, improving excavating efficiency, and to provide a mud-adding material suitably used in civil engineering work such as the tunneling methods. - 特許庁

地山に発進立坑からセミシールド機により掘進管を掘進埋設する工法にあって、予め布設した大口径である仮設管を活用して小口径発進立坑からの掘進を可能とし、狭隘現場からの発進を実現し、作業効率の向上と工期の短縮を図る。例文帳に追加

To carry out starting from a limited work site and improve work efficiency while reducing term of works for pipe-jacking method wherewith jacking pipes are laid in the ground by a semi-shield machine, starting from a starting shaft, by a method wherein the pipe jacking from a small-bore starting shaft is made practicable by utilizing a large-bore temporary-laying pipe laid beforehand. - 特許庁

推進管２を吊下回動させて一端口２ａを大口径の仮設管３Ｂ内に導入してセミシールド機３Ａに連結し、これを稼動させながら元押しジャッキ装置４で押圧することで推進管２を順次連結して推進埋設して行く。例文帳に追加

A jacking pipe 2 is hung down and turned and connected to the semi- shield machine 3A with its opening 2a at one end brought into the large-bore temporary laying pipe 3B, and the jacking pipes 2 are successively pushed forward and laid, being pressed by the primary jacking device 4, while the semi-shield machine is operated. - 特許庁
