综合管廊通风分区长度的研究
Length of ventilation compartment of utility tunnels
摘要:
按入廊管线要求的通风性质将综合管廊分为不同类别舱室,按管廊运营中要求的通风应对措施将通风模式分为不同工况。通过对不同长度通风分区的综合管廊的通风系统计算,从通风效果、消防安全、景观效果、投资造价等多角度进行分析,认为综合管廊合理的通风分区长度可以超过传统综合管廊设计的200 m制约,以减少风亭数量,提升道路景观整体协调性。
Abstract:
According to the ventilation characteristics required by the entrance pipelines, divides the utility tunnel into different types of cabins. Divides the ventilation mode into different conditions based on the ventilation countermeasures required in the operation of tunnels. Through calculating the ventilation system of utility tunnels with different length of ventilation compartments and performing the analyses from the perspectives of ventilation effect, fire safety, landscape effect and investment cost, considers that the length of ventilation compartment can exceed the 200 m restriction of the traditional utility tunnel design, which can reduce the number of air pavilions and enhance the overall coordination of road landscape.
