Tunnel portal structure of road-tunnel combined section in alpine region
The invention relates to the technical field of tunnel protection, and particularly discloses an alpine region road-tunnel combined section tunnel portal structure which comprises an arch-shaped lining, a road plate and a lifting pile assembly, the arch-shaped lining is detachably connected with the road plate, the lifting pile assembly is arranged on the lower side of the road plate, and the lower side of the road plate is fixedly connected with the upper side of the lifting pile assembly. The arch-shaped lining is separated from the deep soil-containing ice layer through the mode that the arch-shaped lining and the road plate of the open cut tunnel are arranged in a separated mode, the change of the deep soil-containing ice layer cannot affect the arch-shaped lining of the open cut tunnel, the road plate is divided into the upper plate and the lower plate, and the upper plate and the lower plate are connected through the elastic structure; the supporting piles of the road plate penetrate through the deep soil-containing ice layer to be directly driven into the underground soil layer, the supporting piles can stretch out and draw back up and down to enable the road plate to move upwards and descend, the road plate is separated from the deep soil-containing ice layer, the change of the deep soil-containing ice layer does not affect the road plate, and the practicability of the tunnel portal is improved.
本发明涉及隧道防护技术领域，具体公开了一种高寒地区路隧结合段隧道洞门结构，包括拱形衬、路板和升降桩组件，所述拱形衬与路板可拆卸连接，所述升降桩组件设于路板下侧，所述路板下侧与升降桩组件上侧固定连接。本发明通过明洞的拱形衬和路板分离设置的方式使得拱形衬脱离深厚含土冰层，使得深厚含土冰层的变化不会对明洞的拱形衬造成影响，并且路板分为上板和下板，并通过弹性结构来进行连接，并且路板的支撑桩穿过深厚含土冰层直接打入地下的土层，并且支撑桩可以上下伸缩来使得路板上移和下降，使得路板脱离深厚含土冰层，使得深厚含土冰层的变化不会影响路板，增加洞门的实用性。
