单线铁路隧道仰拱曲模选型及施工线型质量控制

Selection of Curved Form of Inverted Arch and Quality Control of Construction Line Type for Single Track Railway Tunnel

以衢宁铁路庆元隧道出口仰拱施工为背景,探讨单线铁路隧道仰拱曲模选用拼装式曲模适用性、实用性,以及对仰拱线型质量控制方法和施工技术。现场经使用效果良好,适用于小断面单线铁路隧道,能够确保施工质量,降低工程成本,实用性很强。

Based on the construction of the inverted arch at the exit of Qingyuan tunnel of Quning railway, this paper discusses the applicability and practicability of the selection of the assembled curved arch for the single track railway tunnel, as well as the quality control method and construction technology for the inverted arch line. It is suitable for small section single track railway tunnel, can ensure the construction quality, reduce the project cost, and has strong practicability.
