复合土工膜冬季施工措施

时间:2019-12-19已阅读过: 19次

        施工环境温度在 5—40℃为宜,由于HDPE土工膜具有热胀冷缩的特性,因此在温度低的时候,铺设HDPE防渗膜是要紧一些;而温度高时铺设要松一些;需要注意的是夏天铺设HDPE防渗膜是要避开中午高温的时候施工。随着填埋深度的增加,在垃圾填埋场边坡上使用的土工布将承受长时间的沿着织物方向的应力。在这种情况下,若土工布发生蠕变便会降低其各项技术指标。由于纤维结构的原因,长丝土工布的抗蠕变性能明显优于短丝土工布。以上就是关于土工膜的焊接要从哪个方向进行的介绍,希望对大家有所帮助。如果您还有其他的问题或疑问欢迎拨打我们的热线电话或给我们留言!

       复合土工膜冬季施工措施必须掌握工程项目概略,工程勘察施工工地,当场机器设备驱动力物品的供求平衡,讨论工程施工方法,当场试焊质量检测。 复合土工膜在标准的工作温度下是可以工程施工的,因本身具备优秀的抗寒性,其应用工作温度为高溫110℃/超低温-70℃ .复合土工膜在铺设完成后,会存在一些施工缺陷,包括在焊接时由于局部接缝不当,造成一定长度的窄缝在搬运过程中产生的损坏由于施工机械和工具而刺破基础不均匀沉降使膜撕裂过高水压造成的膜局部 刺 穿这些缺陷主要是施工操作造成的,也是难免的。
