Tunnel thermal insulation layer structure in seasonal frozen soil area and construction method
The invention relates to the technical field of tunnel heat preservation, and particularly discloses a seasonal frozen soil area tunnel heat preservation layer structure and a construction method, the seasonal frozen soil area tunnel heat preservation layer structure comprises a tunnel open cut tunnel, an inner heat preservation layer and an outer heat preservation layer, backfill soil needs to be used for backfilling above the tunnel open cut tunnel, the inner heat preservation layer is located on the inner wall of the tunnel open cut tunnel, and the outer heat preservation layer is located in the backfill soil; detachable telescopic mechanisms are arranged on the two sides of the open cut tunnel, the other ends of the telescopic mechanisms are connected with protective shells, outer heat preservation layers are arranged in the protective shells, a plurality of anchor rods are arranged below the protective shells, the telescopic mechanisms comprise telescopic rods, the telescopic rods comprise fixed rods and movable rods, the movable rods are installed in the fixed rods in a penetrating mode, and the fixed rods are hinged to connecting sleeves. The movable rod is hinged to the protective shell, and a temporary supporting assembly is arranged between the fixed rod and the movable rod. The technical problem that the service life of the open cut tunnel is shortened due to the fact that the backfill can deviate as time goes on and the protection effect on the open cut tunnel after the backfill deviates is reduced is solved.
本发明涉及隧道保温技术领域，具体公开了一种季节性冻土区隧道保温层结构以及施工方法，包括隧道明洞、内保温层和外保温层，隧道明洞上方需要使用回填土进行回填，内保温层位于隧道明洞内壁，外保温层位于回填土内，隧洞明洞两侧均设置有可拆卸的伸缩机构，伸缩机构另一端连接有保护壳，保护壳内设置有外保温层，保护壳下方设置有若干组锚杆，伸缩机构包括伸缩杆，伸缩杆包括固定杆和活动杆，活动杆穿装在固定杆内，固定杆铰接在连接套上，活动杆铰接在保护壳上，固定杆与活动杆之间设置有临时支撑组件。解决了回填土随着时间的推移，会出现偏移的情况，回填土偏移后对隧道明洞的保护作用降低，从而降低了隧道明洞的使用寿命的技术问题。
