邻近营业线挡墙顶推施工技术研究

Study on the Construction Technology of the Jacking Construction of Retaining Wall of Adjacent Business Lines

结合郑徐客专徐州枢纽邻近营业线挡墙顶推施工技术展开研究,阐述了郑徐客专徐州枢纽邻近营业线悬臂式挡墙顶推的施工作业方法,因郑徐客专徐州枢纽邻近营业线安全风险大,原位浇筑需在天窗点施工,采用挡墙顶推为为今后邻近营业线挡墙施工提供了一些可借鉴的经验。

Based on the jacking construction technology of the retaining wall of the adjacent business line of Xuzhou Junction of Zhengzhou-Xuzhou passenger dedicated line, this paper expounds the construction method of the cantilever retaining wall jacking. Because of high security risk in construction, the in situ pouring needs to be constructed in the skylight point. The application of retaining wall jacking provides some reference for the adjacent line retaining wall construction in the future.
