この発明は、シールド掘進機、特に大深度用大型シール
ド掘進機におけるカッタービットの交換方法と、この方
法を実施する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for replacing a cutter bit in a shield excavator, particularly a large shield excavator for deep depths, and an apparatus for implementing this method.
シールド掘進機は、そのシールド本体前部に装備したカ
ッターヘッドを回転させ、カッターヘッド前面に取着し
た多数のカッタービットによって切羽を切削し、切削さ
れた土砂はカッターヘッド後方に形成したカンタ−チャ
ンバー内に取り込んでスクリューコンベヤ、排水管等に
よって外部に排出してトンネルを掘削していくものであ
る。The shield excavator rotates the cutter head installed at the front of the shield body, cuts the face with a large number of cutter bits attached to the front of the cutter head, and the cut earth and sand is stored in a canter chamber formed at the rear of the cutter head. A tunnel is excavated by taking the waste into the interior and discharging it to the outside via a screw conveyor, drainage pipe, etc.
ところで、トンネルの掘削が進行してカッタ−ビットの
損耗が生じると、掘削を中耕した状態でカッタービット
の交換が行われる。By the way, when tunnel excavation progresses and the cutter bit becomes worn out, the cutter bit is replaced while the excavation is being partially tilled.
従来は、この損耗したカンタ−ビットの交換には、作業
員がカッターチャンバー内に入り、カッターヘッドと切
羽との間に作業空間をつくってカッタービットを一つ一
つ手作業で交換することが行われている。Conventionally, to replace worn out canter bits, workers had to enter the cutter chamber, create a working space between the cutter head and face, and manually replace each cutter bit one by one. It is being done.
ところが、シールド掘進機が大型のものになると、カッ
タービット単体も大型になり重量も増し、個数も多くな
り、これを作業員の手作業で交換するとなると労力負担
が大きくなり、しかも、狭隘な空間における苛酷な作業
を強いられて作業能率面からもますます悪化するもので
ある。However, as the shield excavator becomes larger, the cutter bit itself becomes larger, weighs more, and the number of pieces increases.Replacing these cutter bits manually increases the labor burden and requires less space. As a result, workers are forced to perform grueling work, which further deteriorates their work efficiency.
さらに、シールド掘進機が大深度用ともなると、作業員
の手作業で行うカッタービット交換作業には、次ぎのよ
うな準備作業を採らざるを得なくなる。Furthermore, when shield tunneling machines are used for deep-depth operations, the following preparatory work must be performed for the cutter bit replacement work, which is performed manually by workers.
先ず、凍結工法や薬液注入工法によって地盤改良を行う
必要がある。この地盤改良によってはじめて作業員がカ
ンタ−チャンバー内からカッターヘッドと切羽との間に
出てカッタービットの交換作業を行う空間を形成するこ
とができる。First, it is necessary to improve the ground using freezing methods or chemical injection methods. Only through this ground improvement can a space be created in which a worker can come out from inside the canter chamber between the cutter head and face to replace the cutter bit.
しかし、現実には、充分な安全強度を得るための地盤改
良は、長期間にわたる作業となり、この間、トンネルの
掘削が途絶える。However, in reality, ground improvement to obtain sufficient safety strength is a long-term task, and tunnel excavation is interrupted during this time.
また、地盤改良後における実際のカッタービット交換作
業としては、低温環境下における作業となり、これに圧
気工法を併用するとなると、作業環境としては低温・高
圧となって、特殊な訓練を受けた作業員でないと従事で
きなかったり、作業時間の面からも制約を受ける等、作
業者にとってはますます苛酷な環境下での作業を強制さ
れることになり、カッタービットの交換を困難にする。In addition, the actual cutter bit replacement work after ground improvement must be done in a low-temperature environment, and if the pressure air method is used in conjunction with this, the work environment will be low-temperature and high-pressure, requiring specially trained workers. Otherwise, the workers will be forced to work under increasingly harsh conditions, such as not being able to work or being restricted in terms of working time, making it difficult to replace the cutter bit.
この発明は上記の点に鑑みなされたものであって、シー
