Description

一种PE复合土工膜
技术领域
本发明涉及施工材料技术领域，尤其涉及一种PE复合土工膜。
背景技术
土工膜被广泛用于地铁隧道、垃圾填埋等领域，具有防渗的作用。现有的土工膜排水性能较差。在雨天时，往往容易造成积水，进而造成土工膜的破裂，对土工膜的防渗形成造成破坏。
发明内容
本发明为了解决现有技术上述缺点，提出一种PE复合土工膜。
为实现上述目的，本发明采用如下技术方案：
一种PE复合土工膜，包括主体、基板；主体包括第一层和第二层，第一层设置在第二层的上方，第二层的材质为PE，第一层和第二层之间通过胶水层连接在一起，第一层设置有若干限位槽，限位槽的槽底贯通至胶水层；基板的上侧设置有若干蓄水槽并向下凸出有凸起，凸起至少部分设置在限位槽内，基板和第一层之间形成有第一排水道，基板设置有若干第一落水孔，第一落水孔内设置有滤网，第一落水孔和第一排水道连通。
进一步的，第一层设置有若干第二落水孔，胶水层设置有若干第二排水道，第一排水道通过第二落水孔和第二排水道连通。
进一步的，凸起呈上大下小的圆台形。
进一步的，凸起呈矩阵布置。
进一步的，第二排水道的延伸方向相同。
和现有技术相比，本发明提供的一种PE复合土工膜具有以下有益效果：1.PE材质具备较好的防渗性能和强度；2.第一排水道保证了较好的排水性能；3.结冰时所形成的框型结构有利于增加基板和主体之间的稳定性。
附图说明
图1为本申请的实施例的示意图。
图2为本申请的实施例的图1的A-A剖视图。
图3为本申请的实施例的排水时的示意图。
图4为本申请的实施例的结冰时的示意图。
图中：主体11、第一层111、限位槽1111、第二落水孔1112、第二层112、胶水层113、第二排水道1131、基板12、蓄水槽121、凸起122、第一排水道123、框型结构1231、第一落水孔124、滤网1241。
具体实施方式
下面通过实施例，并结合附图，对本发明的技术方案作进一步具体的说明。
参见图1至图4。一种PE复合土工膜，包括主体11和基板12。主体11包括第一层111和第二层112，第一层111设置在第二层112的上方，第二层112的材质为PE，第一层111和第二层112之间通过胶水层113连接在一起，第一层111设置有若干限位槽1111，限位槽1111的槽底贯通至胶水层113，基板12的上侧设置有若干蓄水槽121并向下凸出有凸起122，凸起122至少部分设置在限位槽1111内，基板12和第一层111之间形成有第一排水道123，基板12设置有若干第一落水孔124，第一落水孔124内设置有滤网1241，第一落水孔124和第一排水道123连通。
第一层111设置有若干第二落水孔1112，胶水层113设置有若干第二排水道1131，第一排水道123通过第二落水孔1112和第二排水道1131连通。
凸起122呈上大下小的圆台形。
凸起122呈矩阵布置。
第二排水道1131的延伸方向相同。
实施例原理：
在使用时，将主体11铺设在地面上，主体11呈倾斜状，从而便于排水。此时，第二排水道1131从上至下倾斜延伸。参见图3。将基板12铺设至第一层111上侧，凸起122嵌入限位槽1111，从而增加基板12的稳定性。基板12的上侧铺设土壤。滤网1241防止土壤流失。当雨天时，雨水先后经滤网1241、第一排水道123、第二落水孔1112、第二排水道1131向下流走，参见图3。雨水积累至蓄水槽121，有利于保持土壤的湿润，从而使得土壤上的植物较好的生长。冬天时，土壤结冰，此时，在第一排水道123、第二落水孔1112和第二排水道1131内残留的水将凝结成框型结构1231，从而增加基板12和主体11之间的稳定性。参见图4。
应当理解的是，对于本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本发明所附权利要求的保护范围。
