城市综合管廊通风系统关键技术研究

Resistance Analysis of Ventilation System of Utility Tunnel

本文通过对综合管廊工程通风系统的理论分析及实地测试,得出不同舱室通风量的设计标准、不同断面和管线布置形式下的通风阻力的计算以及在电力舱的电缆散热量,避免仅按通风次数造成通风量偏大的现象,实现减少通风系统土建投资及其运行费用,从而减少综合管廊工程的总体运行费用。

Based on the comprehensive utility tunnel construction ventilation system of the theoretical analysis and field testing,it is concluded that different cabin ventilation rate of the design standard,under different section and pipeline layout of ventilation resistance calculation and the electric tank cable heat,avoid only according to the number of ventilation caused the phenomenon of air quantity is big,to reduce the ventilation system construction investment and operation cost,thus reducing the overall operating cost of comprehensive utility tunnel engineering.
