城市管道疏通需要的不仅仅是技术?

排水管道淤积污垢淤积效果:排水污水含有大量的悬浮固体,在材料的相对密度大于1固体材料,属于固体杂质的沉降,大颗粒泥沙等有机残留物,金属粉末,等等,沉降速度和沉降取决于固体颗粒的相对密度和粒径的侵入,侵入性的流速和流量,所以需要专业人员来疏通。流量小、流量大、相对密度和粒径大的可沉降固体杂质沉降速度和沉降量大,意味着固体杂质在管道中积累快。在一起,因为管道中的流速不能维持一个恒定的理想自洁流速或设计流速,此外,也有一些抵抗管道及其附属结构的变化,如管道方向盘,突然增加管径,等等,这些变化越大,局部阻力越大,局部水头损失越大。因此,管道内淤积污泥是不可避免的。
  Sedimentation and fouling effect of drainage pipeline: drainage sewage contains a large number of suspended solids. When the relative density of the material is greater than 1 solid material, it belongs to the settlement of solid impurities, organic residues such as large particles of sediment, metal powder, etc. the settlement speed and settlement depends on the relative density of solid particles and the invasion of particle size, invasive flow rate and flow rate, so it needs professional personnel to dredge. Small flow, large flow, large relative density and particle size of the settleable solid impurities, which means that the solid impurities accumulate quickly in the pipeline. Together, because the velocity in the pipeline cannot maintain a constant ideal self-cleaning velocity or design velocity, in addition, there are some changes that resist the pipeline and its auxiliary structure, such as the steering wheel of the pipeline, sudden increase of pipe diameter, etc., the larger these changes, the greater the local resistance, and the greater the local head loss. Therefore, it is inevitable to deposit sludge in the pipeline.

  城市排水管道清理和维护方法的分类和原则:城市排水管道清理和维护方法分为清理和疏浚两大类。
  Classification and principle of cleaning and maintenance methods of urban drainage pipeline: cleaning and maintenance methods of urban drainage pipeline are divided into two categories: cleaning and dredging.
  (一)城市排水管道养护的清洗原则:
  (1) Cleaning principle of urban drainage pipe maintenance:
  也就是说,增加管道的水头差,加上水流压力,增加流量,流量清洗管道的积累,也就是说,大流量松懈或冲走的污水管道可以把积累,更大流量交通暂停的污水可以积累材料。这类清洗包括城市排水管道清除维护方法有:水力冲蚀、机械冲蚀。
  That is to say, increase the head difference of the pipeline, plus the flow pressure, increase the flow, and clean the accumulation of the pipeline with flow. That is to say, the sewage pipeline with large flow slack or washed away can accumulate materials, and the sewage with larger flow and traffic suspension can accumulate materials. This kind of cleaning includes the cleaning and maintenance methods of urban drainage pipes: Hydraulic Erosion and mechanical erosion.
  (2)当管道淤积过多,甚至形成淤塞时,清洗方法无法处理,则需要疏通管道,清除淤塞。
  (2) When the pipeline is silted up too much or even silted up, the cleaning method can not deal with it, so it is necessary to dredge the pipeline and remove the silted up.
  清理及维修市区排水管道的疏浚原则:
  Dredging principles for cleaning and maintenance of urban drainage pipelines:
  也就是说,机器直接作用于堆积,使其通过污水输送或人工直接清除出管道。这类疏浚方法包括人工疏浚、竹(玻璃纤维竹)疏浚、绞车疏浚和钻杆疏浚。
  That is to say, the machine acts directly on the accumulation, making it directly clear of the pipeline through sewage transmission or manual. Such dredging methods include manual dredging, bamboo (fiberglass bamboo) dredging, winch dredging and drill pipe dredging.
