    • 【課題】効率よく地盤の掘削作業を行うことが可能な掘削方法等を提供する。【解決手段】不透水層に達する筒状の止水壁10を地盤1に構築した後、止水壁10の内側の地盤1の掘削に応じて、壁体部材21を筒状に組み立てた掘削用壁体20を止水壁10の内側で下降させる。これにより地盤1の掘削を行う。このようにして掘削を行った掘削箇所1bに構造物30を構築した後、掘削用壁体20を下端部から順次解体して個々の壁体部材21を回収しながら、構造物30の周囲を埋め戻す。【選択図】図1
    • 要解决的问题:提供能够有效地执行地面开挖工作的挖掘方法等。解决方案:在地面1中构造到达不透水层的圆柱形切割壁10之后,用于挖掘的壁体20, 其中壁体构件21组装成圆筒形,根据切割壁10内的地面1的挖掘,在切割壁10的内部下降。因此,挖掘地面1。 在挖掘位置1b处构造结构30,其中以这种方式进行挖掘。 随后,用于挖掘的壁体20从下端被顺序拆卸,并且在单个壁体构件21被回收的同时,结构30的周边被回填。

    • PROBLEM TO BE SOLVED: To provide a circular casing for a shaft with which, while including lubricant supply means, smooth shaft digging work can be performed by preventing the lubricant supply means from being the resistance when rocking or turning the circular casing or from hindering discharge of internal sediment by means of a grab bucket or the like.SOLUTION: In a circular casing for a shaft, on a pipe wall of a steel circular casing body 11, a slit 12 is formed in parallel with a central axis, and a steel pipe 13 for lubricant supply having an outer diameter substantially equal to the thickness of the pipe wall is buried in the slit 12. There is no protrusion on an inner surface of the circular casing 10, so that smooth shaft digging work can be performed. Notches 11a to be filled with weld metal in welding upper and lower steel circular casing bodies are provided at both sides of the steel pipe 13 on an end face of the pipe wall of the casing body 11. Therefore, when joining the upper and lower casings by welding, the notches 11a are filled with welding so that the lubricant can be prevented from being spread over the entire end face of the steel pipe 13 and that the number of locations to pay attention to regarding the leakage of the lubricant can be reduced.
    • 要解决的问题:为了提供一种用于轴的圆形壳体,通过该圆形壳体可以同时包括润滑剂供给装置,通过防止润滑剂供给装置在摆动或转动圆形壳体时产生阻力或阻止放电,从而可以进行平滑的轴挖掘作业 的内部沉积物。解决方案:在用于轴的圆形壳体中,在钢圆形壳体主体11的管壁上,与中心轴平行形成狭缝12,并且钢 具有与管壁厚度大致相等的外径的润滑剂供给用管13埋设在狭缝12中。圆形壳体10的内表面上没有突出部,能够进行平滑的轴挖掘作业。 在钢管13的两侧,在壳体主体11的管壁的端面上设置焊接上,下钢圆筒状体的焊接金属的切口11a。因此,在将上下壳体 通过焊接,通过焊接来填充切口11a,从而可以防止润滑剂在钢管13的整个端面上扩散,并且可以减少注意润滑剂泄漏的位置的数量。

    • PROBLEM TO BE SOLVED: To provide a liner plate and a deep foundation construction method, which achieves safe work and improves work efficiency.
      SOLUTION: In this liner plate, four supporting parts 53 are inserted into recessed parts 12a of a connection ring 12, respectively, and the upper face of a flange 53a on the upper side is abutted on the rear surface of a flange 12b on the upper side of the connection ring 12 to fix on a frame piece 52. Thus, a liner plate unit 11 is supported by four supporting parts 53 through the connection ring 12. The liner plate units 11, 11 are mutually connected through the connection rings 12, 12 outside a vertical shaft 2.
