    管道疏通办法及施工流程
    Pipeline dredging method and construction process
    1.查看清洗对象;宾馆.饭店.住所等洗浴间的浴池.喷头.盆池等衔接的下水管道;厕所内的大便池.小便池及其衔接的管道;厨房用的洗菜池.地漏及其衔接管道以及它们衔接室外污水井的管道等。在清洗之前,首要应弄清楚管道的架构,并了解其运用年限以及运用情况.阻塞情况.埋入和显露部分有无损坏等问题。假如发现设备和管线现已损坏要先替换,方可进行清洗作业。在查询设备管线的一起要了解到管线的原料中除了铸铁和陶瓷外,是否还含有其他的原料,如有水泥等结构资料的设备和管道,清洗时最好与体系离隔,防止腐蚀。
    1. Check cleaning objects; hotels, hotels, residences, bathrooms, showers, basins and other connected sewers; toilets, urinals, urinals and their connecting pipes; kitchen sinks, floor drains and their connecting pipes and their connecting pipes to outdoor sewage wells. Prior to cleaning, it is important to understand the structure of the pipeline, its service life and usage, blockage, buried and exposed parts are not damaged. If it is found that the equipment and pipelines are damaged, they must be replaced before they can be cleaned. In the inquiry equipment and pipelines together to understand the raw materials of the pipeline in addition to cast iron and ceramics, whether there are other raw materials, such as cement and other structural data equipment and pipelines, cleaning is best separated from the system to prevent corrosion.
    2.分段;在清洗前先将需要清洗的管线分红若干个清洗段。关于不同的建筑物,不同楼层数.单元数的下水道和设备容积也不尽相同。将管道分红几个小的清洗段也是为了愈加便利的清洗,可以根据下水道的容积.楼层的凹凸.清洗是否便利,以及分段的可能性来进行分段。一般以一个单元内的三.四层楼为一段较合理。

    2. section; before cleaning, divide the cleaned pipeline into several cleaning sections. For different buildings, the number of floors and the number of units of sewer and equipment are also different. Dividing pipes into smaller sections for easier cleaning can also be done according to the size of the sewer, the concavity and convexity of the floor, the convenience of cleaning, and the possibility of segmenting. Generally, a three - four storey building in one unit is more reasonable.

    3.堵;清洗中的重要一环。首要将自上而下的榜首个分段处堵死,此分段处一般在管道干线的调查孔(手孔)处。然后将其他并联管线和与大气相通的管道通口堵死,只留下榜首个分段最上方的两个通口:一个口用来注入清洗液,一个口用来扫除气体。堵口处应能接受1—2公斤/厘米2的压力,不然清洗时注入的清洗液会压破管道。堵口处若有阀门,最好不完全依托阀门堵口,由于运用长远的阀门不易关严。
    3. block; an important part of cleaning. The first section of the top-down list will be blocked, this section is generally in the main pipeline survey hole (hand hole). Then the other parallel pipelines and the atmospheric pipelines were blocked, leaving only two openings at the top of the first section: one for injection of cleaning fluid, and one for gas removal. The plug should be able to withstand pressure of 1-2 kg/cm 2, or the cleaning fluid injected during cleaning will break the pipe. If there is a valve at the plug, it is better not to rely entirely on the valve plug, because long-term use of the valve is not easy to close.
    4.试漏;堵口作业结束后,要进行必要的试漏。试漏的办法是这样:从该段最上方的进液口处向里加水至加满停止,并调查水位是否下降,若下降,查找漏处并补好漏口;若能坚持水位,即可进行下一步操作。
    4. leak test; after plugging operation, necessary leak test is necessary. The method of leak test is as follows: add water from the top inlet to the filling stop, and investigate whether the water level drops, if it drops, find the leak and fill the leak; if the water level can be maintained, the next operation can be carried out.
    5.清洗;依照以上过程对所分段顺次进行清洗,加酸的办法同试漏加水的办法相同,一般选用浸泡式清洗。若清洗速度过慢或没到达清洗要求时,可适当替换清洗液继续清洗,直至洗净。榜首段洗净后,依照同样的办法清洗,第二段并一起翻开榜首段的堵口,使清洗液流入第二段清洗,在清洗液浓度不够的时候可替换部分清洗液进行清洗,直至洗净。第三段.第四段顺次进行。一个单元清洗结束后翻开一切的堵口,然后放入很多的水冲刷,使体系康复正常。
    5. Cleaning; according to the above process, the stages are cleaned sequentially. The method of adding acid is the same as the method of leaking test and adding water. Generally, soaking cleaning is chosen. If the cleaning speed is too slow or does not reach the cleaning requirements, can be properly replaced by cleaning fluid to continue cleaning, until the cleaning. After the first section of the list is cleaned, follow the same method to clean, the second section and together open the plug in the first section of the list, so that the cleaning fluid into the second section of the cleaning, when the concentration of the cleaning fluid is not enough, can replace part of the cleaning fluid for cleaning, until the cleaning. The third paragraph. Fourth paragraphs proceed sequentially. After a unit is cleaned, open all the plugs, and then put a lot of water to wash away, so that the system is back to normal.
