铁路地下段范围综合管廊关键节点设计方案探讨

Discussion on Key Nodes Design Scheme of Comprehensive Pipe Gallery in the Underground Section Scope of Railway

根据铁路地下段范围情况,有针对性地对其范围内综合管廊关键节点设计方案进行探讨,全面论述了综合管廊的入廊管线、舱室布置、断面形式以及总体结构布置等内容。根据建设经验以及铁路运维管理要求,对铁路地下段范围综合管廊的连接通道、交叉节点、人员出入口、通风逃生吊装口等关键节点设计方案进行分析,统筹铁路及综合管廊建设要求,利用变换调整节点结构构型的方式,从功能性和实用性角度,提出了优化方法思路和合理的优化方案。

According to the scope of the underground section of the railway,this paper discusses the design scheme of the key nodes of the comprehensive pipe gallery within its scope,and comprehensively discusses the pipeline of utility tunnels,cabin layout,section form and overall structural layout of the comprehensive pipe gallery.According to the construction experience and the requirements of railway operation and maintenance management,the design schemes of key nodes such as connection channel,intersection node,personnel entrance and exit,ventilation and escape hoisting opening of the comprehensive pipe gallery in the underground section of the railway are analyzed.According to the construction requirements of railway and comprehensive pipe gallery,the optimization method and reasonable optimization scheme are put forward from the perspective of functionality and practicability by using the way of transformation and adjustment of node structure configuration.
