Mountainous area soft earth highway tunnel entrance semi-light and semi-dark entering-hole construction method
The invention relates to a mountainous area soft earth highway tunnel entrance semi-light and semi-dark entering-hole construction method and relates to the field of highway tunnel construction. The mountainous area soft earth highway tunnel entrance semi-light and semi-dark entering-hole construction method comprises the steps of tunnel foundation treatment, specifically, brush slope processing is performed on a tunnel, and a bias-voltage wall is cast in the tunnel; construction of an A segment of protection arch, specifically, one steel frame is erected at an A segment of the tunnel, and onefeet-lock small guide pipe is set, meanwhile, one concrete protection arch is cast, and one large pipe shed guide pipe is pre-buried; construction of a B segment of protection arch, specifically, onesteel frame is erected at a B segment of the tunnel, one feet-lock small guide pipe is set, meanwhile, one concrete protection arch is cast, and one large pipe shed guide pipe is pre-buried; sleeve arch construction, specifically, the steel frames are erected at the A-segment protection arch and the B-segment protection arch, and one pipe shed guide pipe is buried, meanwhile, one concrete sleevearch is cast, and one large pipe shed guide pipe is pre-buried; arch top backfill, specifically, cement-stabilized macadam soil backfill is performed on the A-segment protection arch, the B-segment protection arch and the sleeve arch segment; and one large pipe shed is set up. The mountainous area soft earth highway tunnel entrance semi-light and semi-dark entering-hole construction method has theadvantages of high safety performance and less influence by the rising water level of rivers and gullies in the high water period.
本发明涉及一种山区中软土公路隧道进口半明半暗进洞施工方法，涉及公路隧道施工领域。它包括处理隧道地基，对隧道进行刷坡处理，在隧道内浇筑偏压墙；施作A段护拱，在隧道的A段架设钢架，并设置锁脚小导管，同时浇筑混凝土护拱，并预埋大管棚导向管，施作B段护拱，在隧道的B段架设钢架，设置锁脚小导管，同时浇筑混凝土护拱，并预埋大管棚导向管；施作套拱，在A段护拱和B段护拱上架设钢架，并埋设管棚导向管，同时浇筑混凝土套拱，并预埋大管棚导向管；拱顶回填，对A段护拱、B段护拱及套拱段进行水泥稳定碎石土回填；搭设大管棚。具有安全性能高、受丰水期河流及溪沟水位上涨的影响较小的优点。
