摘要/Abstract

摘要： 在城市地下电缆敷设发展过程中，曲线拉管等非开挖技术在穿越长距离障碍物方面具有对环境影响小、工艺简单、适用性广等特点，得到了越来越广泛的应用。结合曲线拉管施工工程的实际情况，对施工原理、施工注意事项进行了分析，对现场顶进机械的顶进力、场地沉降等数据进行了监测和分析。结果表明，通过监控动态反馈，有效地检验了曲线拉管施工方案，取得了良好的效果，可为其他同类曲线拉管工程的顺利实施提供借鉴和参考。

Abstract: In development of the city underground cable laying, the trenchless technologies, such as the curved tube pulling technology, due to their characteristics of the little influence on the environment, the simple process and the wide usability in laying the line passing through long distance obstacles, are used more and more widely. Combining with the practical situation of curved tube pulling construction project, the principle of the construction and the matters needing attention in the construction were analyzed. The jacking force data of the site jacking machinery and the field settlement data were monitored and analyzed. The result shows that by monitoring and dynamical feedback, the curved tube pulling construction scheme was verified effectively; and the favorable effects were obtained. The scheme provides certain reference for similar curved tube pulling construction projects.
