TUNNEL LINING CONCRETE AND CONSTRUCTION METHOD OF LINING CONCRETE
PROBLEM TO BE SOLVED: To provide a tunnel lining concrete which is hardly gets damaged even when various external forces are applied thereto, and a construction method of lining concrete.SOLUTION: The tunnel lining concrete is formed by sequentially lining concrete on the inner surface of a tunnel wall in an axial direction and which has a joint part on the lining part. The tunnel lining concrete has a joint part in the lining part. The joint part is formed by chamfering an inner edge of the lining plane of an existing concrete and an inner edge in a plane of the newly formed concrete opposing to the lining plane. The chamfered part has a curved surface.SELECTED DRAWING: Figure 2
【課題】覆工コンクリートに様々な外力が作用しても、損傷が生じにくいトンネルの覆工コンクリートおよび覆工コンクリートの構築方法を提供することである。【解決手段】トンネルの内壁面に対して軸線方向に順次、コンクリートを打ち継ぐことにより形成され打継ぎ部に目地部を備えたトンネルの覆工コンクリートであって、前記目地部が、既設コンクリートの打継ぎ面の内縁と該打継ぎ面に対向する新設コンクリートの対向面の内縁にそれぞれ設けられた面取り部により形成され、該面取り部が、曲面を備える。【選択図】図２
