摘要
结合甘肃省张掖市集中供热工程直埋单式轴向型膨胀节施工实践体会,从安装前的检查、安装中的重点要求、系统试压与清洗、管路保温、回填等方面介绍了其安装施工要点。4个供暖期的正常供热运行证明该种施工技术具有合理性和可行性。
Based on the construction experience of directly buried single axial expansion joints in central heating project at Zhangye city in Gansu province, presents the construction essentials including the examination before installation, crucial requirements during installation, pressure test and cleanout, pipe insulation, and backfill. The normal running of four heating periods proves that the construction technique is reasonable and feasible.
