Abstract

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.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a stone veneer structure and a construction method for a tunnel door wall. Background technique [0002] Dry-hanging stone materials for building exterior walls are widely used. Some traffic tunnel projects try to directly transplant them to the stone surface of the tunnel door wall. However, due to certain hidden safety hazards in this method, no substantial progress has been made. The main reason is that traffic tunnels are different from construction projects. The stress on the door walls of traffic tunnels is very complicated. There are not only climatic and environmental influences such as seepage water, ice and snow, and natural wind force, but also external forces such as driving vibration and vehicle piston wind force. Therefore, the stone facing structure of the tunnel door wall needs to comprehensively consider the above factors in order to ensure safe operation of th...
