【摘要】：建筑室内给排水管道支架设计施工,普遍直接套用国标图集而鲜有专门的验算分析。但高铁地下正线区间由于隧道内列车运行速度快,隧道具有风荷载大、不易检修、事故危险性高等特点,在侧壁后锚固安装的给排水管道支架需进行专项验算,以保障结构安全。从工程设计实例出发,在考虑列车风荷载影响下,采用受力分析和数值计算的方法,对在正线区间两侧水平安装的给排水管道支架及锚栓的强度进行了设计验算,并提出提高管道支架结构安全的建议。
[Abstract]:In the design and construction of indoor water supply and drainage pipe support, the national standard atlas is generally applied directly without special calculation and analysis. However, due to the high speed of train running in the underground main line of high-speed railway, the tunnel has the characteristics of large wind load, difficult to examine and repair, and high risk of accident, it is necessary to carry out special checking calculation for the water supply and drainage pipeline support installed after Anchorage on the side wall. To ensure structural safety. Based on the engineering design example and considering the influence of the train wind load, the strength of the water supply and drainage pipe support and the anchor bolt installed horizontally on both sides of the main line section is calculated by using the method of force analysis and numerical calculation. The suggestion of improving the safety of pipe support structure is put forward.
