装配式大截面轻轨方桩施工技术研究

Study on Construction Technique of Assembled Large Cross-section Square Pile for Light Rail Project

随着城市地铁的持续建设和人们对环保意识的不断提高,大型地铁车站或换乘枢纽等深基坑工程越来越多,装配式混凝土大截面方桩的应用也愈来愈普遍。济南地铁近期规划R1~R3线,远期规划M1~M6共9条线,将大量应用预制混凝土大截面方桩,以提升施工现场文明形象,缩短工期,确保施工质量,减少现场环境污染,大幅降低工程成本,减少工程安全隐患,从而创造更多效益。

With the fast construction of urban subway and the increase of people＇s environmental awareness, more and more deep foundation pit projects are constructed, such as large subway station or transfer hub, and application of assembled concrete square pile with large cross section are becoming more and more popular. Precast concrete large cross-section square pile will be comprehensively used in construction of nine subway lines in Jin＇an, including short-term subway lines R1 to R3 and long-term subway linesM1 to M6, to promote the civilization on construction site, shorten construction schedule, ensure construction quality, reduce environmental pollution on construction site and construction cost, prevent potential safety risk and create more benefits.
