双层多舱综合管廊标准断面及其附属设施设计

Design of Double-layer Multi-compartment Utility Tunnel Standard Section and Its Auxiliary Facilities

以三舱、四舱、五舱等双层多舱形式为例,通过对双层舱室排列组合的分析研究,归纳总结出双层管廊"上下结构""左右结构""一字型""田字型"等多种标准断面形式。双层综合管廊的舱室布置、节点设计更加复杂,详细介绍了下层管廊的逃生、通风、排水、吊装等各种功能节点的设计方法,以确保管廊全寿命周期的安全。

Arrangement and combination of double-layer utility tunnel was analyzed by taking three compartments,four compartments,five compartments and other multi-compartment forms as examples,and standard section forms such as"upper and lower structure","left and right structure","line pattern"and"criss-cross pattern"of double-layer utility tunnel were summarized.Compartment layout and joint design of double-layer utility tunnel were more complicated,and design methods of escape,ventilation,drainage,hoisting and other functional nodes of the lower layer utility tunnel were introduced in detail in order to ensure the safety of the whole life cycle of the utility tunnel.
