大型的排水管道有没有一米七的?

作者: admin    来源:http://www.laobingguandao.com  时间:2019-08-12    人气:
  目前,正在建设综合管道走廊,以避免连年内涝灾害的再次发生。排水管道的使用频率也相应增加了几倍。他们是什么?管、HDPE双壁波纹管,钢筋聚乙烯螺旋波纹管,双墙钢塑复合管道,内部和外部涂层塑料管,四种产品,此外,有混凝土管,PVC波纹管、PE管道,等等,总之,“团队”很多,如何选择特定的设计和施工要求。问题是,这些大排水沟有1.7米长吗?
  At present, the state is building comprehensive pipeline corridors to avoid the recurrence of waterlogging disasters in successive years. The use frequency of drainage pipes has also increased several times. What are they? Pipes, HDPE double-wall corrugated pipes, reinforced polyethylene spiral corrugated pipes, double-wall steel-plastic composite pipes, internal and external coated plastic pipes, four products, in addition, concrete pipes, PVC corrugated pipes, PE pipes, etc. In a word, there are many "teams", how to select specific design and construction requirements. The question is, are these big drains 1.7 meters long?
  我们不讨论其他产品是什么样子的,或者它们有多大。钢管生产的钢带增强聚乙烯螺旋波纹管直径可达1.7米,通常标为DN1700。当口径如此坚固时,可以认为是一个大项目。该管道主要采用DN300、DN400、DN500三种小口径。一般可以适应中小项目的置换。有1.7米长的大型排水管吗?
  We don't discuss what other products look like or how big they are. The diameter of strip reinforced polyethylene spiral bellows produced by steel pipes can reach 1.7 meters, usually marked DN1700. When the caliber is so strong, it can be considered a big project. DN300, DN400 and DN500 are mainly used in this pipeline. Generally, it can be adapted to the replacement of small and medium-sized projects. Is there a large drainage pipe 1.7 meters long?
HDPE双平壁钢塑复合缠绕管
  当然,双平壁、钢塑复合排水管道也生产直径1.7米,但很少,主要原因是考虑到工程造价和具体设计埋深要求,通过钢带管的建议,而不是选择使用双平壁、钢塑复合排水管道。其价格要高得多,一是产品生产工艺新颖,所谓薄即贵,二是该产品的推广力度较低,一般强度如SN8、SN10、SN12.5、SN16等钢带增强聚乙烯螺旋波纹管都能达到,抢走了它的工作。除非设计院在图纸上注明了产品,否则不会选择使用。
  Of course, double-flat-wall and steel-plastic composite drainage pipes are also produced with a diameter of 1.7 meters, but very few. The main reason is that, considering the engineering cost and specific design requirements of burial depth, through the recommendations of steel strip pipes, rather than using double-flat-wall and steel-plastic composite drainage pipes. Its price is much higher. First, the production process of the product is novel, so-called thin is expensive. Second, the promotion of the product is low. Generally, the strength of steel band reinforced polyethylene spiral bellows such as SN8, SN10, SN12.5, SN16 can be achieved, which robs it of its work. Unless the design institute indicates the product on the drawing, it will not choose to use it.
  HDPE双壁波纹管一般使用在dn200-dn600口径范围内,很多人会问,为什么不用DN700以上呢?由于当HDPE双壁波纹管达到DN700以上时,一般的生产工艺无法达到,而且产品直径越大,环的刚度控制就越困难,在这种情况下,其生产成本甚至可能远远超过钢带增强聚乙烯螺旋波纹管的生产成本。
  HDPE double-wall bellows are generally used in the range of dn200-dn600 caliber. Many people will ask why not use DN700 or more? Because when HDPE double-wall bellows reach DN700 or above, the general production process can not be achieved, and the bigger the product diameter, the more difficult the rigidity control of the ring is. In this case, the production cost is very high. The production cost of steel reinforced polyethylene spiral bellows may be much higher than that of steel strip reinforced polyethylene spiral bellows.
  后面提到的几款产品,如PE排水管的口径,以及混凝土和PVC材料的不常见,当然不是技术问题,通过是需求低的原因。
  Several products mentioned later, such as PE drain pipe caliber, concrete and PVC materials are not common, of course, not technical problems, through the low demand.
  有1.7米长的大排水沟吗?通过以上分析,各种产品都能满足规格要求。如果您还有其他问题,请咨询我。
  Is there a large drainage ditch 1.7 meters long? Through the above analysis, all kinds of products can meet the specifications. If you have any other questions, please consult me.
