The utility model discloses a expansion joint structure of a super long ultra thick anti radiation tunnel roof plate, including a tunnel roof with a telescopic seam. The expansion joint adopts a step type setting. A V type water stop plate is arranged in the middle of each step. The expansion joint is filled with a extrusion plate, and the two sides of the water surface are arranged on both sides of the surface of the expansion joint. The concrete waterproof guide wall, the outer top surface of the concrete waterproof guide wall is closed with stainless steel slider and stainless steel cover plate. This new type of tunnel expansion joint takes into account the radiation prevention technology, sets the expansion joint into a step type, and transversely sets 2 pieces of V type water stop steel plate for waterproof, and the outer side is closed with stainless steel slider and stainless steel cover on the outside. It can prevent water from infiltrating into expansion joints, achieve radiation-proof effect, and satisfy certain decorative effect. It has certain popularization significance.

一种超长超厚防辐射隧道顶板的伸缩缝结构
本技术涉及一种伸缩缝结构,特别涉及一种超长超厚防辐射隧道顶板的伸缩缝结构。
技术介绍
近年来,随着城市化的不断发展,地下结构也越来越多的出现在人们的视线中,但是由于城市环境诸如建筑、地铁线路或其他复杂地形的客观条件的限制,地下结构诸如隧道结构的深度也越来越深,就导致隧道结构往“深厚化”方向发展。特别的对于位于辐射或其他恶劣环境周围建设隧道结构更是要求更高,既要满足防水防渗要求,还要满足方辐射要求,现有的隧道结构的伸缩缝结构已不能满足这种要求。
技术实现思路
本技术的目的在于克服现有技术的缺陷,提供一种集防水、防辐射和装饰于一体的超长超厚防辐射隧道顶板的伸缩缝结构,所述超长超厚防辐射隧道顶板的伸缩缝结构的技术方案是这样实现的:一种超长超厚防辐射隧道顶板的伸缩缝结构,其特征在于:包括设置有伸缩缝的隧道顶板,所述伸缩缝采用台阶型设置,每节台阶的中部横向设置有V型止水钢板,所述伸缩缝内用挤塑板填充,所述伸缩缝迎水面两侧设置有混凝土防水导墙,混凝土防水导墙外侧顶面用不锈钢滑条加不锈钢盖板封闭。进一步的,所述隧道顶板外侧设置有SBS防水卷材,所述SBS防水卷材延伸至所述混凝土导墙顶面并用塑料膨胀螺栓固定。进一步的,所述SBS防水卷材的厚度为3mm。进一步的,所述不锈钢盖板通过与设置在混凝土防水导墙顶面上的不锈钢基座固定相连。进一步的,所述不锈钢盖板中部还设置有防水垫片,所述防水垫片通过不锈钢防水螺栓固定在不锈钢盖板上。进一步的,所述V型止水钢板的厚度为1.2mm。进一步的,所述塑料膨胀螺栓沿伸缩缝方向上按间距500mm设置。进一步的,所 ...
