大连这次暴雨排水压力有多大?

2017-08-07 21:35:01   中国青年网

8月2日至4日,大连迎来几十年未见的特大暴雨,给市内道路交通带来不小压力,给城市基础设施造成一定损害。这场暴雨虽未造成人员伤亡,但在不少方面,也给城市提了醒。

降水量第十强

据气象部门统计

市区平均降水量超过130毫米 是有历史记录以来的第十强

恰逢海水涨潮

8月4日

雨量最大时段恰逢海水涨潮

潮水顶托使各河道水位暴涨 河道沿线暗渠 排水管线饱和

管网超期服役

据市排水处介绍 这次大规模降雨强度超过排水设施受纳能力 导致设施短时排水不及 很多管网“超期服役” 使用多年后管道疏松 造成管道堵塞

排水设施堵塞

各种杂物涌入排水设施 造成排水井和排水管线堵塞 尤其山洪携带大量碎石 泥沙 树枝树叶全部涌向市政道路 造成排水不及 排除时间增加

提醒

人为因素影响

必须有所改变

规范企业排放

部分企业排放的酸碱盐没有达标 造成排水管线腐蚀

管理餐饮排污

有些饭店酒店不按规范设置隔油设施 或者隔油设施清理不及时 直接将污物 油脂排放到城市排水管网 吸附在管壁上 使管内空间越来越小

完善小区设施

部分物业小区自管排水设施失养失修 小区道路雨水井失去收水功能 下雨时雨水直接流到下游的市政道路上 同时垃圾和杂物将排水井盖堵塞 致使路面积水

更加科学施工

部分施工单位在施工过程中将排水管线损坏 造成排水不畅导致积水 路面拓宽改造维修也造成了新的低洼点 道路上行驶的车辆荷载最多5吨 而现在最重达四五十吨 导致排水管道不堪重负

实施雨污分流

市排水处相关负责人表示 我市很多泄洪沟河仍然承担着排放污水的任务 没有实行雨污分流 既影响城市的环境 又影响汛期泄洪 因此必须对排水设施进行增容改造 逐年实施雨污分流

推荐海绵城市

大连计划于2018年完成试点区域的“海绵城市”建设 试点区内75%的雨水将实现就地吸纳和利用 到2020年全市及所辖区市县城市建成区20%以上达到“海绵城市”建设标准 到2030年城市建成区80%以上达到“海绵城市”标准(据大观新闻、新商报)
