长距离曲线顶管技术在电力管道工程中的应用

非开挖技术在市政管道铺设中的应用越来越广泛，从直径50mm通讯光缆-直径3000mm混凝土管道，采用非开挖安装各种管道都变得很普遍。同时，鉴于非开挖技术综合效益优越性、环境友好型施工特点，也逐渐被工程建设方、社会所接受和认可。泥水平衡顶管技术是非开挖最为成熟的技术之一，在城市市政设施建设中也起着举足轻重的作用。采用泥水平衡顶管技术进行城市雨污分流改造已经在国内大量城市取得应用，但是，采用泥水平衡顶管在岩层中铺设直径达2000mm埋深在5m电力管道，在国内为数不多，在福建厦门地区也是尚属首次。通过在工程施工中对设备、施工工艺的摸索和改进，最后采用泥水平衡顶管施工技术成功铺设建设方所要求的电力管道。本工程将为在福建地区采用预管技术铺设大口径长距离、曲线管道提供了指导和借鉴。

The Application of Long-distance Curved Pipe Jacking in Power Pipe Construction

At present, trenchless technology is universally recognized by owner and society for its beneficial and environmental friendly character. As one of the most mature trcnchless technology, slurry balanced pipe jacking is playing important role in municipal construction. However, it is the first time for Xiamen to install a power pipe with 2000 mm in diameter and 5 meter in embedding depth using slurry balanced pipe jacking method, which is uncommon even around China. The power pipe was successfully installed after improvement of construction equipment and technology, which can be referenced by other large diameter power pipe construction engineering.
