Description

一种新型土工膜
技术领域
本发明属于土工膜技术领域，具体涉及一种易发现破损和易于修补的土工膜。
背景技术
土工膜以塑料薄膜作为防渗基材，与增强材料复合（一般为尼龙网或无纺布网）而成的土工防渗材料，主要机理是以塑料薄膜的不透水性隔断土坝漏水通道，以其较大的抗拉强度和延伸率承受水压和适应坝体变形。
现有的土工膜在实际使用中存在以下问题：在进行覆盖施工时，很有可能造成的土工膜的损伤，损伤一般分为贯穿性和非贯穿性，非贯穿性的又分上表面损伤和下表面损伤，损伤导致土工膜的防水性大大折扣，需要及时修补，而土工膜一般铺设面积大，且多为黑色，破损尤其是下表面的破损，不容易被发现，而修补后，修补处没有增强材料，使修补处较为脆弱，即使在修补的材料内添加增强结构强度的材料，但该材料本身也与原有的增强材料不连接，使修补处依旧较为脆弱。
发明内容
针对上述问题，本发明提供一种新型土工膜，该土工膜具有破损保护提示的功能，提醒工作人员及时维修，且修补后，修补处强度高，后期不易漏水。
本发明解决其技术问题所采用的技术方案是：一种新型土工膜，包括透明材质的塑料膜层，所述塑料膜层内设有加强层A和加强层B；
所述加强层A为若干高强度软管A交叉编织而成的网状结构，高强度软管A的管壁不透明，高强度软管A内设有线绳A，所述线绳A由高强度纤维绞合而成，自然状态下，线绳A的长度大于高强度软管A的长度，所述线绳A上设有若干隔断，线绳A和高强度软管A之间填充有染色物；
所述加强层B为若干高强度软管B交叉编织而成的网状结构，高强度软管B的管壁透明，高强度软管B内设有线绳B，自然状态下，线绳B的长度大于高强度软管B的长度，所述线绳B由高强度纤维和遇水变色纤维绞合而成，所述线绳B上设有若干隔断，线绳B和高强度软管之间填充有阻水物。
优选的，所述塑料膜层材质为聚丙烯、聚乙烯、和乙烯-醋酸乙烯共聚物中任意一种。
优选的，所述染色物内混合有阻水物。
进一步优选的，所述染色物为朱砂红或草绿。
优选的，所述阻水物为阻水粉或阻水纱。
优选的，高强度软管的材质为尼龙或聚氨酯。
优选的，所述高强度纤维为玄武岩纤维或高密度聚乙烯纤维。
铺设时，加强层A在上，加强层B在下，当出现非贯穿性损伤，如果损伤出现在上表面，由于强度软管A的管壁不透明，染色物会暴露出来会有明显色差，使伤口处容易被发现，如果损伤出现在下表面，变色纤维会吸水变色，透过加强层A的网格看到，阻水物和隔断防止水在高强度软管B中过度蔓延。
针对不同情况采用不同的警示方法，加强层A采用染色物，在土工膜表面无水的情况也可以起到警示的作用，加强层B采用变色纤维，防止下表面水过多稀释掉染色剂，导致警示不明显。
修补方法：当破损处较小时，将破损处清理干净，将伤口两侧加强层内的线绳拉出相连，然后进行修补；当破损处较大时，将破损处清理干净，将加强层内的线绳拉出，选用一样结构的修补块，将修补块上的高强度纤维拉出，与原有的高强度纤维连接，然后进行修补。加强绳上的隔断，可以在加强绳拉出时，带出进水填充物，防止其影响修复。
本发明的有益效果是：具有破损保护提示的功能，提醒工作人员及时维修，针对不同情况采用不同的警示方法，且修补后，修补处强度高，后期不易漏水。
