Tunnel portal wall stone facing structure and construction method
The invention discloses a tunnel portal wall stone facing structure and a construction method. The tunnel portal wall stone facing structure comprises a wall surface, an arch ring, a square facing, a strip-shaped facing, an arc-shaped facing, anchor bolts and the like. The tunnel portal wall stone facing structure has the structural advantages that 1, the structural safety is ensured by comprehensively considering the complex stress condition of a traffic tunnel portal wall; 2, according to the stress characteristics of the stone facing, a certain included angle is formed between the anchor bolts and the wall surface, the structural stress is optimized, and anchor bolt holes are obliquely and upwards filled with mortar, so that materials are saved, and filling is dense; 3, connecting pieces are low in price and high in overall stability, water seepage pipes are additionally arranged between the stone facing and the tunnel portal wall for drainage, gaps are filled with self-compacting concrete doped with polypropylene fiber inorganic fibers, and the crack resistance and durability are improved; and 4, the calculation method is clear in principle, practical and easy to implement, and the safety quality performance is improved, so that the structure has the advantages of being simple in structure, convenient to construct, safe, reliable, attractive, practical, capable of saving resources and the like, and the economic benefits and social benefits are remarkable in combination with the corresponding construction method.
本发明公开了一种隧道洞门墙石材饰面结构及施工方法，包括墙面、拱圈、方形饰面、条形饰面、弧形饰面和锚栓等，其结构优点为：一是通过综合考虑交通隧道洞门墙的复杂受力情况来确保结构安全；二是根据石材饰面受力特点，将锚栓与墙面成一定夹角，优化结构受力，且锚栓孔倾斜向上灌注砂浆，既节约材料又灌入密实；三是连接件价格便宜，整体稳定性强，石材饰面与隧道洞门墙之间增设渗水管排水，空隙内又由掺加聚丙烯纤维类无机纤维的自密实混凝土灌实，提高抗裂性和耐久性；四是计算方法原理清晰、实用易行，提高安全质量性能，故该结构具有构造简单、施工便利、安全可靠、美观实用、资源节约等优点，结合相应施工方法，经济效益和社会效益显著。
