渗水孔 meaning in Chinese

weeper

The special structure of zippered plastic pipe zippered seep holes made a greater seepage quantity on the condition of bare pipe ( no anti - blocking material adopted at the mouth of seep holes ) . so several kinds of anti - seepage material were adopted in the experiment of this part in order to find the proper anti - seepage material ( nonwoven fabrics glued by neoprene ) and working head ( 3m ' s working herd on initial irrigation )
由于拉链式塑料管的独特构造(拉链式渗水孔口) ，裸管(渗水孔口不采用任何防堵材料)情况下渗流量很大，所以本部分试验采用了几种防渗材料试验，最后通过比较分析，找到了合适的防渗材料(氯汀胶粘无纺布)和工作水头(初始灌水时3m工作水头) 。
Negative pressure blockage and biological blockage are two main forms of blockage for the special structure of zippered plastic pipes , so two treatments were made here : ( i ) nonwoven fabrics glued by neoprene and ( ii ) nonwoven fabrics glued by neoprene with a layer of asphalt emulsion applied outside
由于拉链式塑料管的独特构造(拉链式渗水孔口) ，所以它的堵塞主要应是负压堵塞和生物堵塞，为此设2个处理：氯汀胶粘无纺布和氯汀胶粘无纺布并外涂一层乳化沥青进行试验研究。
