Cold-proof, heat-preservation and drainage structure for shallow-buried and bias-pressure tunnel
The invention discloses a cold-proof, heat-preservation and drainage structure for a shallow-buried and bias-pressure tunnel, and belongs to the technical field of tunnel construction. The tunnel comprises a concealed tunnel section and an open cut tunnel section; a first thermal insulation layer structure is arranged on an arch wall among the hidden hole section, the primary support and the secondary lining; a first arch wall drainage system is arranged on the hidden hole section arch wall, and an internal drainage system is arranged in the hidden hole section tunnel; for the open cut tunnel section, a second heat preservation layer structure is arranged on the outer edge of the arch lining of the open cut tunnel section; a second arch wall drainage system is arranged on the open cut tunnel section arch wall, and the internal drainage system is also arranged in the open cut tunnel section tunnel. According to the method, the waterproof structures and the heat preservation layer structures are arranged on the hidden hole section and the open cut hole section of the tunnel, soil moisture entering the heat preservation layer structures is greatly reduced through the waterproof structures, the soil moisture can be discharged in time once entering the heat preservation layer structures, and the situation that the water enters the heat preservation layer structures, frost heaving damage is caused, the heat preservation layer structures are fractured, and the service life of the heat preservation layer structures is shortened is avoided.
本发明公开了一种浅埋偏压隧道防寒保温、排水结构，属于隧道施工技术领域。所述隧道包括暗洞段和明洞段；对于暗洞段，初期支护和二次衬砌之间的拱墙设置有第一保温层结构；暗洞段拱墙上设置有第一拱墙排水系统，暗洞段隧道内部设置有内部排水系统；对于明洞段，明洞段拱部衬砌外缘设置有第二保温层结构；明洞段拱墙上设置有第二拱墙排水系统，明洞段隧道内部也设置有所述内部排水系统。在本发明中，在隧道暗洞段和明洞段均进行防水结构与保温层结构，通过防水结构极大程度减少土体水分进入保温层结构内，一旦进入也能及时排出，避免水分进入保温层结构，造成冻胀破坏，致使保温层结构压裂，减少保温层结构使用寿命。
