Expressway tunnel extension structure and construction method
The invention relates to the field of tunnel construction, and particularly discloses an expressway tunnel extension structure and a construction method.The expressway tunnel extension structure comprises a tunnel lining on an old expressway tunnel and further comprises an upper layer carriageway plate horizontally and fixedly arranged on the lower side of the edge of the tunnel lining; the piles are supported on the lower side of the edge of the tunnel lining, a tunnel circumferential structure is poured between every two adjacent piles, and a lower-layer traffic lane plate is horizontally arranged on each tunnel circumferential structure and located among the piles; and an extended driving space is formed among the piles, the upper-layer traffic lane plate, the lower-layer traffic lane plate and the tunnel peripheral structure. According to the scheme, the tunnel lining on the original old expressway tunnel does not need to be rebuilt, compared with a new tunnel, the operation steps of tunnel lining, excavation and the like in new tunnel building, the construction cost and the use of raw materials can be effectively saved, and the transformation cost can be reduced while transformation can be rapidly completed.
本发明涉及隧道施工领域，具体公开了高速公路隧道扩建结构及施工方法，包括老旧高速公路隧道上的隧道衬砌，还包括：水平固定设置于隧道衬砌边缘下侧的上层行车道板；若干支撑于隧道衬砌边缘下侧的桩柱，相邻两个桩柱之间浇筑有隧道周圈结构，隧道周圈结构上水平设置有下层行车道板，下层行车道板位于若干桩柱之间；桩柱、上层行车道板、下层行车道板和隧道周圈结构之间形成扩展行车空间。本方案中的原有老旧高速公路隧道上的隧道衬砌不需重新建造，相较于新建隧道，能够有效节约新隧道建造中隧道衬砌、开挖等操作步骤和施工成本和原材料的使用，能够快速完成改造的同时降低改造成本。
