滇中新区投建“里子工程”

2017-09-05 09:17:11   中国青年网

总体算来,滇中新区目前在建的3条重点道路的综合管廊共有26.12公里,总造价约12.39亿元,每米投入约4.74万元。

除了建安费用以外,建造综合管廊还需投入大量的人力、物力和时间。工程测算显示,截至目前,空港大道中段项目综合管廊完成约6.7公里,建设期间投入劳动力约120人,各类机械约30台,施工工期约200天,与没有综合管廊的市政道路相比投入大大增加。哨关路、嵩昆路两个工程的建设公司经过测算,综合管廊建造时间约为整个项目建造时间的25%。

综合对比 花12亿元建“里子工程”值得

当前,滇中新区正处于大开发、大建设的关键时期,各方面对资金的需求都很大。新区为何会把12亿元投资在“里子工程”的建设上呢?

相关负责人介绍,滇中新区作为国家级新区,目标是要通过高标准规划、高起点建设,注重科技创新、自主创新,注重经济社会和资源环境协调发展,使新区未来成为具有经济综合实力和竞争力的城市新区。城市综合管廊工程作为地下空间的“生命线”,是城市公共配套的重要组成部分,大力投资合情合理。

每当暴雨来临,因路面、区域严重积水造成生产、生活不便,人们首先诟病的往往是下水道,而地下管廊能有效保障城市地下管线的安全、经济、高效运营,提高城市的管理水平。滇中新区从成立伊始,就高度重视综合管廊的规划建设,并于2016年启动了25公里的地下综合管廊建设。

建设综合管廊,还可以避免“马路拉链”问题对交通和居民出行造成的影响和干扰,降低路面多次翻修的费用和工程管线的维修费用,保持路面的完整性和各类管线的耐久性,便于各种管线的敷设、增减、维修和日常管理,有效利用路下空间,减少架空线与绿化的矛盾,节约城市用地,让城市景观变得更美。

项目建设方负责人告诉记者,综合管廊建设的一次性投资常常高于管线独立铺设的成本。但是,综合管廊的成本效益比,显然不能只看投入多少,要进行系统性、综合性的对比后,才能更好地发现建设综合管廊对城市而言,具有更加长远的经济和社会效益。

未来方向 让智慧综合管廊更上一层楼

近日,国家住建部下发《2017年科学技术项目计划》,滇中新区智慧综合管廊一期工程入列国家科学技术示范(信息化类)项目。

智慧综合管廊可谓是综合管廊的“升级版”。在上述3条道路中,哨关路和嵩昆路综合管廊同时也是新区智慧综合管廊一期工程,合计约18.05公里。其中,哨关路智慧综合管廊全长10.6公里,嵩昆路一期智慧综合管廊总长约7.45公里。管廊内配套有消防系统、给排水系统、通风系统、照明系统、监测系统、电气控制系统等工程,并设置智慧管廊监控室、展示厅等。
