Abstract
本实用新型公开了无碴轨道专用高强土工布，包括软质的聚乙烯网和两层加强筋，其特征在于所述加强筋为网格状，软质的聚乙烯网铺设在两层加强筋之间，并连结为一整体。所述加强筋为整体挤压成型的片状网格。所述聚乙烯网和两层加强筋采用超声波焊接成型为一整体。本实用新型的土工布整体强度高，由于加强筋和软质聚乙烯网组合形成的凹凸面增强了土工布和地基的摩擦力，延长了土工布的使用寿命。
Description
技术领域
本实用新型涉及一种复合土工布，特别是涉及无碴轨道专用高强土工布。
背景技术
土工布是应用于铁路一种地基加固材料。主要作用为软基处理、斜坡防护等。目前国内已发明多种复合土工布，目的都是为了增强土工布的抗拉强度、降低延伸率，延长上工布的使用寿命。在无碴轨道斜坡以及坝基斜坡的应用中还是存在易位移等缺陷。
实用新型内容
无碴轨道专用高强土工布，包括软质的聚乙烯网和两层加强筋(1)，其特征在于所述加强筋(1)为网格状，软质的聚乙烯网(2)铺设在两层加强筋(1)之间，并连结为一整体。所述加强筋(1)为整体挤压成型的片状网格。所述聚乙烯网(2)和两层加强筋(1)采用超声波焊接成型为一整体。
本实用新型的有益效果是：本实用新型的土工布整体强度高，由于加强筋和软质聚乙烯网组合形成的凹凸面增强了土工布和地基的摩擦力，延长了土工布的使用寿命。
附图说明
通过下面结合附图对本实用新型进行描述，本实用新型上述特征和优点将会变得更加清楚和容易理解。
图1是本实用新型无碴轨道专用高强土工布的结构示意图；
图2是本实用新型无碴轨道专用高强土工布的顶视图。
图中，1、加强筋；2、聚乙烯网。
具体实施方式
下面结合附图对本实用新型进行详细的描述。
如图所示，无碴轨道专用高强土工布，包括软质的聚乙烯网和两层加强筋1，其特征在于所述加强筋1为网格状，软质的聚乙烯网2铺设在两层加强筋1之间，并连结为一整体。所述加强筋1为整体挤压成型的片状网格。所述聚乙烯网2和两层加强筋1采用超声波焊接成型为一整体。
