Abstract

易焊接甩边糙面土工膜，包括土工膜本体，土工膜本体上下表面交错设置若干防滑点，土工膜本体上下表面上设置防滑点的区域纵向两侧为光面焊接边，光面焊接边与土工膜本体为一体式结构，防滑点为具有弧形表面的防滑凸点或防滑凹点。本发明在土工膜本体纵向两侧设置光面焊接边，这样在施工过程中土工膜就无需打磨破坏变薄后再焊接，不但省时省力，而且提高了焊接质量，同时防滑点的吸盘式结构也有助于提高土工膜防滑效果，具有结构简单、使用方便的优点。

Description

易焊接甩边糙面土工膜
技术领域
本发明涉及防水材料技术领域，具体涉及一种易焊接甩边糙面土工膜。
背景技术
土工膜以塑料薄膜作为防渗基材，与无纺布复合而成的土工防渗材料，它的防渗性能主要取决于塑料薄膜的防渗性能。目前，国内外防渗应用的塑料薄膜，主要有聚氯乙烯（PVC）和聚乙烯（PE）、EVA（乙烯/ 醋酸乙烯共聚物），隧道应用中还有设计使用ECB（乙烯乙酸乙烯改性沥青共混土工膜）的，它们是一种高分子化学柔性材料，比重较小，延伸性较强，适应变形能力高，耐腐蚀，耐低温，抗冻性能好。
但是目前的土工膜在以往垃圾填埋场、工业防渗、铝厂赤泥堆场等防渗项目应用中经常出现坡面滑坡现象，一方面影响工程的质量和进度，一方面影响土工膜的设计和应用。为了解决这个问题，国外最先采用了糙面膜，但是现有的糙面膜在使用过中发现糙面膜破坏性糙面，影响材料总体性能，而且不能直接焊接，需要打磨破坏变薄后焊接，焊缝强度严重不足，造成工程渗漏隐患，而且现有的糙面膜防滑效果也不尽理想。
发明内容
本发明提供了一种易焊接甩边糙面土工膜，以解决现有技术存在的不能直接焊接和防滑效果差的问题。
本发明包括土工膜本体，解决其技术问题所采用的技术方案是土工膜本体上下表面交错设置若干防滑点，土工膜本体上下表面上设置防滑点的区域纵向两侧为光面焊接边，光面焊接边与土工膜本体为一体式结构，防滑点为具有弧形表面的防滑凸点或防滑凹点。
优选的，上述土工膜本体上面的防滑点为防滑凸点，土工膜本体下面的防滑点为防滑凹点，防滑凹点表面的类似吸盘的结构有助于土工膜与被覆盖物的连接强度。
本发明在土工膜本体纵向两侧设置光面焊接边，这样在施工过程中土工膜就无需打磨破坏变薄后再焊接，不但省时省力，而且提高了焊接质量，同时防滑点的吸盘式结构也有助于提高土工膜防滑效果，具有结构简单、使用方便的优点。
