城市排水能力如此脆弱的原因有哪些?

作者: admin    来源:http://www.laobingguandao.com  时间:2019-09-23    人气:
  当然,暴雨强度和浓度大,降水超过排水能力是造成严重内涝的主要原因。那么,我们城市排水能力如此脆弱的主观原因是什么呢?
  Of course, heavy rainfall intensity and concentration, precipitation over drainage capacity is the main cause of serious waterlogging. So, what is the subjective reason why our city's drainage capacity is so fragile?
  一是排水系统规划设计不合理。
  First, the planning and design of drainage system is unreasonable.
  由于地方财政的短缺和政府成果观的需要,地方城市的可持续发展能力不强,城市防洪标准过低,市政基础设施水平不先进,前瞻性不强。因此,地方政府更注重建设地面上看得见成效的高层建筑,而忽视了地下排水系统。而很少有城市制定了排水系统规划体系,基本上就是开发一个做一个,缺乏长期规划,没有骨干排水管网,每个社区只能靠自己打,怎么能把水排出去呢?
  Because of the shortage of local finance and the need of government achievement view, the sustainable development ability of local cities is not strong, the standard of urban flood control is too low, the level of municipal infrastructure is not advanced, and the foresight is not strong. Therefore, the local government pays more attention to the construction of high-rise buildings with visible results on the ground, but neglects the underground drainage system. However, few cities have formulated drainage system planning system. Basically, they are developing a drainage system, lacking long-term planning and backbone drainage network. Every community can only fight by itself. How can water be discharged?
  二是排水系统施工质量不达标。
  Second, the construction quality of drainage system is not up to standard.
  城市排水系统不仅要有良好的规划设计,还要有良好的施工质量,才能达到预期的设计效果。排水系统工程的质量直接关系到工程的使用和城市排水的能力。一些施工人员认为,排水系统在地面上,是看不见的工程,不要紧,如排水管道接口不符合要求,把泥浆窖井形成一个虚拟,你说如何能经受住暴风雨的考验?
  Urban drainage system not only needs good planning and design, but also has good construction quality, in order to achieve the desired design effect. The quality of drainage system engineering is directly related to the use of engineering and the capacity of urban drainage. Some constructors believe that the drainage system on the ground is an invisible project, it does not matter, such as the drainage pipe interface does not meet the requirements, the mud pit to form a virtual, you say how to withstand the test of storms?
  第三,排水系统的管理和维护不到位。
  Third, the management and maintenance of drainage system is not in place.

  无论城市排水系统有多好,如果不认真管理和维护,仍然无法达到预期的排水效果。比如,长时间不去检查,长时间不去清理淤泥,长时间不去总结,排水系统怎么能畅通无阻,又怎么能经得起风暴呢?
  No matter how good the urban drainage system is, if it is not carefully managed and maintained, the expected drainage effect can not be achieved. For example, how can the drainage system be unimpeded, and how can it withstand storms without checking for a long time, cleaning up the mud for a long time and summarizing for a long time?
  四是城镇居民综合素质不高。
  Fourth, the comprehensive quality of urban residents is not high.
  在一个城市,只有良好的基础设施如排水系统是不够的,只有合格的质量是不够的,只有专业部门的管理和维护是不够的,而广大居民的关心和爱护,尊重和保护。现在认为,每个城市已成为一个巨大的建筑工地,建筑垃圾随处可见,提高尘飞,街道,环卫工人清理泥浆在路上,甚至简单的图将泥土杂物直接进入CMC,居民的方便了泥浆进入下水道或CMC等内容,清楚地看到CMC覆盖也走了,你能说,排水系统处于很好的状态么?
  In a city, only good infrastructure such as drainage system is not enough, only qualified quality is not enough, only the management and maintenance of professional departments is not enough, and the care, love, respect and protection of the broad masses of residents. Now think that every city has become a huge construction site, construction waste everywhere, improve dust, streets, sanitation workers clean mud on the road, and even a simple map will directly enter the mud debris into CMC, residents facilitate the mud into sewers or CMC content, clearly see the CMC coverage has gone, you can say, drainage system. Are they all in good condition?
