综合管廊内给水架空钢管支吊架布置设计

Design of Overhead Steel Pipeline Support and Hanger Arrangement for Water Supply in Utility Tunnel

随着综合管廊建设的快速发展,廊内给水管道的建设规模越来越大,但廊内给水管道的设计规范体系相对薄弱,设计人员缺少完善的规范体系作为技术指导。从廊内给水架空钢管管道的特点出发,参考室外给水排水行业及石油化工行业的相关设计规范与技术资料,总结出一套适用于综合管廊内给水架空钢管支吊架布置的设计方法,并从平面设计、竖向设计及特殊节点设计三个方面分别举例阐述了支吊架布置的设计要点,为管道系统的安全运行创造条件。

The rapid development of utility tunnel leads to an increasing scale of the water supply pipeline construction in the utility tunnel.However,standard systems for design of the water supply pipeline in the utility tunnel are limited and imperfect,resulting in the designers lack a systematic standard system as technical guidance.A design method for arrangement of overhead steel pipeline support and hanger for water supply in utility tunnel was summarized according to the characteristics of the overhead steel pipeline for water supply in the utility tunnel and referring to the relevant design specifications and technical data of outdoor water supply and drainage industry and petrochemical industry.In addition,the key points for design of support and hanger arrangement were illustrated from three aspects of plane design,vertical design and special node design to create conditions for safe operation of a pipeline system.
