问题1与地下直埋管道线相比,地下综合管廊的建设和运营具有哪些特点根据住建部数据,50年地下综合管廊的建设费用为1.2亿元/公里,50年地下直埋管线的建设费用为0.73亿元/公里;50年地下综合管廊的维修运行费为0.4亿元/公里,50年地下直埋管线的维修运行费为0.93亿元/公里。与地下直埋管线相比,新建管廊的初始建设成本较高,但维修运行费用较小。地下综合管廊的经济社会效益随着运营期的增加而逐渐凸显。
Question 1 What are the characteristics of the construction and operation of underground integrated corridors compared with buried underground pipelines? According to the data from the Ministry of Housing and Urban-Rural Development, the construction cost of underground integrated corridors for 50 years is 120 million yuan / km and buried underground for 50 years Construction cost is 73 million yuan / km; 50 years of underground integrated corridor maintenance fee is 40 million yuan / km, 50 years buried underground pipeline maintenance and operation fee of 93 million yuan / km. Compared with the buried underground pipeline, the newly constructed pipe gallery has higher initial construction cost but less maintenance and running costs. The economic and social benefits of the underground integrated pipe gallery gradually become more prominent as the operating period increases.
