[Scope of Claim for Utility Model Registration] (1) A cylindrical wall for lining a drilled hole, which is arranged in a multiple drilled hole and used for lining the drilled hole, which has arc-shaped segments. A plurality of cylindrical main walls assembled in the circumferential direction and having openings along the axial direction are formed, and these main walls are arranged with the openings facing each other, and one end of the openings and the other ends of the openings are connected to each other. In a cylindrical wall body for lining an excavation hole, each of which is connected via a branch segment, a middle pillar is built between these opposing branch segments, and these are further connected in the axial direction. , an opening is formed in the middle pillar and the branch segment in a direction transverse to the cylindrical wall, and a bolt insertion hole passing through between both openings is formed, and the bolt insertion hole is formed in the middle pillar and the branch segment. A cylindrical wall body for lining an excavated hole, characterized in that a middle column and a branch segment are connected by tightening a bolt inserted through the hole with a nut. (2) The branch segment is a steel segment, and the middle pillar is made of steel, and the steel middle pillar and the branch steel segment have openings formed in a direction transverse to the cylindrical wall, and Joint plates for mutual connection are provided, and bolt insertion holes communicating with both openings are formed in these joint plates,
The cylindrical wall for lining an excavated hole according to claim 1, wherein the steel central column and the branch steel segment are connected by tightening the bolt inserted through the bolt insertion hole with a nut. body.
