渡槽止水结构

Abstract

本实用新型提供了渡槽止水结构，包括聚乙烯嵌缝板A和聚乙烯嵌缝板B，聚乙烯嵌缝板A和聚乙烯嵌缝板B胶合连接，聚乙烯嵌缝板A顶端的中部设置有环形连接垫，环形连接垫顶端的中部固定安装有聚乙烯嵌缝立柱，聚乙烯嵌缝板A顶端的四个边角处均安装有定位块，还包括密封罩体，密封罩体顶端的中部嵌设安装有立柱导向套，密封罩体内腔的四个边角处均安装有定位长条，每个定位长条的内侧均设置有对应定位块的配合凹口。本实用新型在密封罩体顶端的中部嵌设安装立柱导向套，密封罩体内腔的四个边角处均安装有定位长条，每个定位长条的内侧均设置有对应定位块的配合凹口，这样能够取代传统的丙乳砂浆层，降低整个止水结构对渡槽的重力负担。
