缆线型综合管廊设计要点探讨

Discussion on Key Design Points of Cable Utility Tunnel

地下综合管廊包括干线型综合管廊、支线型综合管廊和缆线型综合管廊(简称缆线管廊),其中缆线管廊主要负责将市区架空的电力、通信、广播电视等缆线容纳至埋地的管廊中。近几年,地下综合管廊迅速发展,而国内、外研究主要集中在干、支线型综合管廊,对于缆线管廊的研究很少。本文结合国内形势,提出了缆线管廊的优势和建设时机的选择,探讨了缆线管廊在我国的应用前景,并结合国内、外工程经验,介绍了缆线管廊的一般设计原则以及缆线管廊主通道、工作井的几种设计方案,并提出了每种设计方案的适用情况,可供同类工程参考。

Utility tunnel includes arterial utility tunnel, branch utility tunnel and cable utility tunnel, and the cable utility tunnel is mainly responsible for the installation of overhead lines ( electricity, communication, radio and television and other cable lines) in the urban area to the buried pipeline. In recent years, utility tunnel has developed rapidly. Domestic and external researches mainly focus on arterial utility tunnel and branch utility tunnel, and few studies have been done on cable utility tunnel. Combining with domestic situation, this paper puts forward the advantage of the cable pipe rack and construction timing and discusses the application prospect of cable utility tunnel in our country. Combined with engineering experience at home and abroad, this paper outlines the general design principle of cable utility tunnel and several kinds of design scheme. The application of each design scheme is also presented, these conclusions can provide a reference for the similar projects.
