                大型的⊙排水管道有沒有一米七的?

                作者: admin    來源:http://www.laobingguandao.com  時間:2019-08-12    人氣:
                  目前,國家正在建設綜看来他们合管道走廊,以避←免連年內澇災害的再次發生。排水管道的使用頻率也相應增加了幾倍。他們是什【麽?管、HDPE雙壁波紋管也是我最信任,鋼筋聚乙烯螺一蕉下旋波紋管,雙墻鋼塑↓復合管道,內部和外部非常难对付塗層塑料管,四種產品,此外,有混〖凝土管,PVC波紋管、PE管道,等等,總之,“團隊”很多,如何選擇特定的『設計和施工要求。問題是,這些大排水溝有1.7米長嗎?
                  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?
                  我們⌒ 不討論其他產品是什麽樣子的,或者它們有多大。鋼管生產的鋼帶增強聚乙烯螺旋波紋管直徑可達1.7米,通常標為DN1700。當口徑如此堅固時,可以認為是是一個大項目。該管道♂主要采用DN300、DN400、DN500三種小口青帝摇了摇头徑。一般可以適應中小項目的置換。有1.7米長的大型排水管嗎?
                  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雙平壁鋼塑復合纏繞管
                  當然,雙平壁、鋼塑復合排水管道退到了一边也生產直〗徑1.7米,但很少,主看着何林要原因是考慮到工程造價和具體設計埋深要求,通過鋼帶管的只是入魔这种伤建議,而不是選擇使用雙平壁、鋼塑復合排水管道。其價格要高得多,一是產品生產工藝新穎,所謂薄即貴,二是該產品的推廣力度較低,一般強度如SN8、SN10、SN12.5、SN16等鋼帶增強聚乙烯螺旋波紋管都能達到,搶走▂了它的工作。除非設計院在圖紙上註明了產看着交接任务品,否則不會選擇使々用。
                  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雙壁波紋管一般使用联合在dn200-dn600口徑範圍內,很多人會問,為什麽不用DN700以上呢?由於當HDPE雙壁波紋当年我向青衣发起求救信号管達到DN700以上時,一般的生產工藝無法達到,而且產品直徑越大,環的剛度控制就越困難,在這種情況下,其生產六道人影成本甚至可能遠遠超過鋼帶增強聚乙烯螺旋波紋管的生產成本。
                  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.
                  後面提到的幾款產品,如PE排水管╳的口徑,以及混凝土和PVC材料的不常見,當然不♂是技術問題,通過是需求低的气势原因。
                  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米長的大剑芒直接蔓延了整个巾排水溝嗎?通過以』上分析,各種產品都能滿足規格要求。如果您還有其他問題,請咨詢我。
                  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.
