Abstract
この物品は、トンネル内の両側あるいは片側のトンネル側壁に該トンネル側壁と間隔を有して敷設される通路壁用ブロックに関するものである。トンネル側壁と通路壁用ブロックの間の空間にはケーブルなどの収納部が形成され、上面には通路が形成される。該通路壁用ブロックは、略垂直に立ち上がる通路壁部と、該通路壁部の下端よりトンネル側壁側に向かって略直角方向へ折曲し、かつ略水平方向に向けて延出する通路壁固定部とにより略Ｌ字状をなして構成されている。通路壁用ブロックは、トンネル側壁と間隔をあけてトンネルの側壁側に向かって通路壁固定部が延出するよう敷設される。また、通路壁部の長手方向両端側からは通路壁固定部の延出方向と同じ方向に向かって突出する一対のアンカーボルトが設けられ、前記通路壁部の先端側からは、通路壁部の長手方向に向かって間隔をあけて７本の小アンカーボルトが前記通路壁固定部の延出方向と同じ方向に向かって突出するよう設けられている。This article relates to passage wall blocks which are laid on both sides or one side of a tunnel with a gap therebetween. A storage space for cables and the like is formed in the space between the tunnel side wall and the passage wall block, and a passage is formed on the upper surface. The passage wall block includes a passage wall portion that rises substantially vertically, and a passage wall fixing portion that is bent substantially perpendicularly from the lower end of the passage wall portion toward the tunnel side wall and extends substantially horizontally. It is configured in a substantially L shape by the portion. The passage wall block is laid so that the passage wall fixing portion extends toward the side wall of the tunnel with a gap from the tunnel side wall. Further, a pair of anchor bolts projecting in the same direction as the extending direction of the passage wall fixing portion is provided from both longitudinal direction end sides of the passage wall portion, and the passage wall portion extends from the tip end side of the passage wall portion. Seven small anchor bolts are provided at intervals in the longitudinal direction so as to protrude in the same direction as the extending direction of the passage wall fixing portion.
