浅谈绳锯法拆除上跨铁路营业线明洞技术

On the Technology of Overcrossing Railway Business Line Open Cut Tunnel Demolition with Wire Saw Method

铁路营业线上拆除既有构筑物施工最主要的考虑因素是保证铁路营业线运营秩序和施工中既有设备安全防护,为了满足上述两个主要条件,本文研究解决了在不影响既有铁路设备安全和不干扰铁路营业线运营的前提下,安全拆除上跨铁路营业线明洞施工方法,有效利用较短的维修天窗点分阶段拆除上跨铁路营业线明洞,解决了营业线行车干扰、夜间施工噪音污染、保证了铁路运营设备安全等问题,为今后上跨铁路营业线构筑物拆除提供了有益借鉴。

In the construction of the demolition of existing structure on railway business lines, the main consideration is to ensure the operating order of the railway business line and the safety protection of the existing equipment. In order to meet the two main conditions, this paper studies the construction method of the demolition of the overcrossing railway business line open cut without affecting the safety of the existing equipment and disturbing the operation of the railway business line. The short maintenance skylight point is effectively used to remove the overcrossing railway business line open cut. The problems like business line traffic interference, night construction noise pollution and railway operating equipment safety are solved. It provides helpful reference for the demolition of overcrossing railway business line structure in the future.
