为什么说缠绕管材代替传统管势不可挡?

  hdpe中空壁缠绕管的表面强度和刚度比水泥管,特别是钢筋混凝土管,盘管实际hdpe中空壁属于“软管”,在正确的设计和铺设施工情况下,hdpe中空壁缠绕管和周围的土共同承担荷载,因此,hdpe缠绕管不需要混凝土空心墙“刚性管”,如强度和刚度,能满足埋的机械性能的要求。缠绕管内壁光滑,阻力小,水通量大。在相同直径下,缠绕管的水流速度比混凝土管的水流速度大。当地形有坡度时,绕线管管径可减小,工程量小。
  The surface strength and rigidity of HDPE hollow wall winding pipe are higher than that of cement pipe, especially reinforced concrete pipe. The actual HDPE hollow wall of coil pipe belongs to "hose". Under the correct design and laying construction conditions, HDPE hollow wall winding pipe and surrounding soil bear the load together. Therefore, HDPE winding pipe does not need "rigid pipe" of concrete hollow wall, such as strength and rigidity, It can meet the requirements of buried mechanical properties. The inner wall of the winding pipe is smooth, the resistance is small, and the water flux is large. Under the same diameter, the flow velocity of the winding pipe is higher than that of the concrete pipe. When the terrain has a slope, the diameter of the winding pipe can be reduced and the work amount is small.
  水泥管密封很差,在联合国内平界面混凝土管只有一个环混凝土密封,很难确保无渗漏的施工,结合混凝土管刚性管,一个轻微的动作(如土壤不均匀沉降)会导致关节损伤,此外,水泥管使用硫化橡胶圈密封,绕组与热塑性弹性体密封圈密封管接头,前者比后者的使用寿命短,而缠绕管的连接和密封有一系列严格的要求,保证不会泄漏。
  The sealing of cement pipe is very poor. In the United Nations, there is only one ring concrete seal for the flat interface concrete pipe. It is difficult to ensure the construction without leakage. Combined with the rigid pipe of concrete pipe, a slight action (such as uneven settlement of soil) will cause joint damage. In addition, the cement pipe is sealed with vulcanized rubber ring, and the winding and thermoplastic elastomer sealing ring seal the pipe joint. The former has a shorter service life than the latter, There are a series of strict requirements for the connection and sealing of the winding pipe to ensure no leakage.

  Hdpe空心壁缠绕管是一种内径管;壁厚包括开螺纹的地方,但不仅是这里,还包括壁厚为单层的地方。来料应提供产品检验报告、合格证、安装说明书、抽样试验和主试环刚度。环刚度的选择与埋深的深度有关,但具体多少等级的环刚度的设计应该基于承载力的基础,管道的建设基础,地下水位的高度,道路的材料和埋深的转换。
  HDPE hollow wall wound pipe is an inner diameter pipe; the wall thickness includes the place where the thread is cut, but not only here, but also the place where the wall thickness is single layer. Incoming materials shall be provided with product inspection report, certificate, installation instruction, sampling test and main test ring rigidity. The selection of ring stiffness is related to the depth of buried depth, but the design of ring stiffness should be based on the foundation of bearing capacity, the foundation of pipeline construction, the height of groundwater level, the material of road and the conversion of buried depth.
  中空壁缠绕管缠绕成型,强度,通常是SN8 SN4,每平方米4000 n的压力,PVC双壁波纹管、HDPE材料、中空壁缠绕管是HDPE材料,性价比高双壁波纹管,中空壁缠绕管的成本高。hdpe缠绕管的管座也有一些要求。应铺一层约20厘米厚的沙。这样做的目的是为了增加hdpe缠绕管底部与地面的接触面积,从而有效的保护管道。
  The hollow wall wound pipe is wound and molded, with strength of SN8 Sn4, 4000 n / m2. PVC double wall corrugated pipe, HDPE material and hollow wall wound pipe are HDPE material, with high cost performance ratio and double wall corrugated pipe. The cost of hollow wall wound pipe is high. There are also some requirements for HDPE wound pipe socket. A layer of sand about 20cm thick should be laid. The purpose of this is to increase the contact area between the bottom of HDPE winding pipe and the ground, so as to effectively protect the pipe.
