如果边坡焊接特殊部位要怎样处理土工膜

   2025-05-14 2380

边坡交汇处即坝坡拐弯处,土工膜铺设和焊接均属特殊情况,库区的边坡与库底的交汇处,此处在设计上多有盲沟,要根据实际状况特殊裁剪。

相邻两幅的焊接是先焊接好后,再压往盲沟内。再适宜地调整好管套的位置并用热风焊枪临时固定,和渗沥液穿坝管上,并用不锈钢箍加固。

在此区域内,操作人员要精心测量,先把膜顺着坝面铺设在距盲沟1.5米远以外处再与库底膜相,把土工膜裁剪成上宽下窄的倒梯形。

膜的损坏原因主要就是这些,我们一定要尽量避免造成的损坏现象,没有规定用于保护防渗土工膜的土工织物衬垫材料造成的。

以上就是关于如果边坡焊接特殊部位要怎样处理土工膜的具体说明。
