Half-cut bamboo tunnel portal type
The invention provides a half-cut bamboo tunnel portal type which comprises a ground base body, a mountain body arranged on the ground base body, a concealed tunnel lining and an open cut tunnel lining which are arranged in the mountain body and the ground base body, a cut surface arranged on the open cut tunnel lining, an inverted arch backfilling layer arranged in the concealed tunnel lining and the open cut tunnel lining, and an inverted arch backfilling layer arranged on the ground base body, the half-cut bamboo tunnel portal type comprises an open cut tunnel lining, a portal structure arranged on the front side of the portal structure and arranged outside the open cut tunnel lining, and two protection structures symmetrically arranged on the front side of the portal structure and connected with the open cut tunnel lining, the half-cut bamboo tunnel portal type can effectively protect the portal structure through the arranged protection structures, and is matched with the portal structure to stabilize the open cut tunnel lining, so that the service life of the open cut tunnel lining is prolonged, and the service life of the open cut tunnel lining is prolonged. When the arrangement space of the tunnel portal is insufficient, the height of the retaining wall in the protection structure can be adjusted, so that the cutting starting point of the cutting surface of the lining of the open cut tunnel is synchronously lifted to be flush with the retaining wall, the space required by the arrangement of the portal is reduced, and the problem that the bamboo cutting type portal cannot be adopted due to insufficient space of the tunnel portal in the past is solved.
本发明提供了一种半削竹隧道洞门型式，包括：地面基体，设置在地面基体上的山体，设置在山体与地面基体内的暗洞衬砌与明洞衬砌，设置在明洞衬砌上的削切面，设置在暗洞衬砌与明洞衬砌内的仰拱回填层，设置在地面基体上，并置于明洞衬砌外部的洞门结构，对称设置在洞门结构前侧上，并与明洞衬砌相连的两个防护结构，该半削竹隧道洞门型式通过设置的防护结构，可以有效对洞门结构进行防护，并配合洞门结构，对明洞衬砌进行稳固，在隧道洞门布设空间不足时，可以调整防护结构中挡墙高度，进而使得明洞衬砌削切面的起削点同步抬高与挡墙平齐，降低门洞布设所需空间，解决了以往隧道口空间不足无法采用削竹式洞门的问题。
