Large thin-wall drainage tunnel built on side slope and construction method of large thin-wall drainage tunnel
The invention discloses a large thin-wall drainage tunnel, particularly discloses a large thin-wall drainage tunnel built on a side slope and a construction method of the large thin-wall drainage tunnel, and belongs to the technical field of design and construction of water conservancy and hydropower construction engineering structures. According to the large thin-wall drainage tunnel built on the side slope and the construction method of the large thin-wall drainage tunnel, surrounding rock stability and excavation forming in the construction period are facilitated, and combined stress with a lining layer in the tunnel is achieved. The large thin-wall drainage tunnel comprises a drainage tunnel body, the large thin-wall drainage tunnel further comprises an unsymmetrical pressure strengthening anchoring system, and the bearing capacity of rock mass, located on one side of a slope, of the drainage tunnel body is enhanced through the unsymmetrical pressure strengthening anchoring system. The construction method comprises the steps that firstly, the outer anchoring layer is fixed to a stable side slope through the outer anchoring layer base and the crown anchor cable, then the suspended ceiling anchor rods and the outer anchoring layer anchor rods are constructed, finally, the large drainage tunnel is excavated layer by layer, and the in-tunnel supporting system and the in-tunnel consolidation drainage system are constructed layer by layer while the large drainage tunnel is excavated layer by layer.
本发明公开了一种大型薄壁泄水隧洞，尤其是公开了一种建于边坡上的大型薄壁泄水隧洞及其施工方法，属于水利水电建设工程结构物设计建造技术领域。提供一种利于施工期围岩稳定及开挖成型，与洞内衬砌层联合受力的建于边坡上的大型薄壁泄水隧洞及其施工方法。所述的大型薄壁泄水隧洞，包括泄水隧洞本体，所述的大型薄壁泄水隧洞还包括偏压加强锚固系统，泄水隧洞本体位于边坡一侧的岩体通过偏压加强锚固系统增强其承载能力。所述的施工方法为先通过外锚固层基座和冠顶锚索将外锚固层固定在稳定的边坡上，然后施工吊顶锚杆和外锚固层锚杆，最后逐层开挖大型泄水隧洞，并在逐层开挖大型泄水隧洞的同时逐层进行洞内支护系统与洞内固结排水系统施工。
