摘要
新型管材HPDE双壁波纹管施工采用热熔连接工艺,实施中通过创新改进工艺,保证了波纹管接口严密牢固,在密闭性检验中,渗水量达到最严格美国检验标准。
The new type HPDE double-wall corrugated pipe construction uses the hot melt connection craft,in the implementation through the innovation improvement craft,had guaranteed ripple pipe interface close firmly,in the confined tests,the seep quantity achieves the strictest US inspection standards.
