当前,我国已成为全球地下管网建设规模最大、速度最快的国家。这张“看不见、摸不着”的地下管网,默默托举着我们习以为常的生活。用一组数字,走近这张隐秘而庞大的网络。

从清晨洗漱、午后喝茶,再到夜晚洗去一身疲惫,每天,119.9万公里的供水管线,默默输送着数百万吨生活用水;在看不到的墙体内,104万公里的燃气管网正安静地把天然气送到燃气灶和热水器,让一顿热饭、一场热水澡变得触手可及。

1月的寒冬里,室温20摄氏度的舒适背后,是54.62万公里的热力管网在昼夜不停地循环。

6月的雨季中,路面积水快速退去,则要归功于99.36万公里的排水管网,默默守护着城市不被“内涝”困扰。

从供水、排水、燃气到热力,这张总规模超378万公里的城市地下管网还在加速扩张。“十五五”时期,我国城市地下管网的投资力度将进一步加大,新增投资需求约5万亿元。

老旧管网加速更新,智慧监测系统也正逐步铺开——一座座城市的地下,一张更安全、更聪明、更有韧性的隐形网正在加速筑牢城市的生命线。
