Anti-freezing heat preservation structure of large-section tunnel deeply-buried central ditch in alpine region
The invention belongs to the technical field of tunnel engineering, and particularly relates to an anti-freezing heat preservation structure of a deep-buried central ditch of a large-section tunnel in an alpine region, the anti-freezing heat preservation structure comprises a concrete base, and a drainage pipeline is fixedly mounted on the surface of the concrete base; a heat preservation layer is fixedly connected to the outer surface of the drainage pipeline, and a fine sand cushion layer is arranged on the outer surface of the heat preservation layer. The outer surface of the drainage pipeline is fixedly connected with an annular pipeline, the outer surface of the annular pipeline is fixedly connected with a plurality of center pipes, and the center pipes are arranged on the outer surface of the annular pipeline in a circumferential array mode; a first drainage cold-proof seat is arranged on the outer surface of the drainage pipeline; the surface of the first drainage cold-proof base is fixedly connected with a connecting pipe arranged corresponding to the annular pipeline. The anti-freezing heat preservation structure can prevent water flowing slowly for a long time from being frozen in the ditch in the hole. Ice in the trench is prevented, and the durability of the tunnel is improved to a certain extent.
本发明属于隧道工程技术领域，具体的说是一种高寒地区大断面隧道深埋中心水沟的防冻保温结构，包括混凝土基座，所述混凝土基座的表面固定安装有排水管道；所述排水管道的外表面固定连接有保温层，所述保温层的外表面设置有细砂垫层；所述排水管道的外表面固定连接有环形管道，所述环形管道的外表面固定连接有中心管，所述中心管的数量设置多个，且呈圆周阵列设置在环形管道的外表面；所述排水管道的外表面设置有第一排水防寒座；所述第一排水防寒座的表面固定连接有与环形管道呈对应设置的接管；此防冻保温结构能避免长时间下缓缓流动的水冻结在洞内水沟；防止沟内结冰，在一定程度上提高了隧道的耐久性。
