谈大口径直埋供热管线施工要点

Discussion on the construction key points of large diameter direct buried heating pipeline

负荷集中,远距离输送的大温差集中供热已经成为现阶段的新型集中供热模式,长输管线基本以直埋敷设为主。结合工程实际经验,从大口径直埋供热管线的安装工艺、流程以及关键节点技术方面进行了详细论述,指导下一步合理组织施工措施,精细化施工管理,有效的减少资源浪费,大大缩减施工工期,提高了工程效率,保证工程质量。

The large temperature difference central heating of load concentration,long-distance transmission had become a new central heating mode at this stage,the long-distance transmission pipeline mainly as direct buried laying,combining with the engineering practical experience,from the installation process,flow and key node technology aspects of large-diameter direct buried heating pipeline made detail discussion,guided next reasonable organization construction measures,fine construction management,effectively reduced the waste of resources,greatly reduced the construction period,improved the engineering efficiency,ensured the engineering quality.
