Abstract
The invention relates to the field of arch wall and inner wall supporting protection reinforcement members of underground engineering important infrastructures, in particular to a pre-embedded ductile iron frame-reinforced concrete combined tunnel wall plate. The combined tunnel wall plate comprises a ductile iron frame, a steel bar truss combined part and a reinforced concrete member, wherein one side of the ductile iron frame is in connecting combination with the steel bar truss combined part, the combined ductile iron frame and the steel bar truss combined part are placed in a shaping template to be filled with concrete so as to be in health solidification, and then the firmly combined pre-embedded ductile iron frame-reinforced concrete combined tunnel wall plate is formed. The pre-embedded ductile iron frame-reinforced concrete combined tunnel wall plate is a one-time lining arch wall support protective system for mainly reinforcing arch walls of sections with special stresses and unfavorable geology of geological structure faults, quicksand, softness, loess and highland encountered in tunnel construction to solve the problems of low reliability of safety and quality, short service life and low construction efficiency in the traditional reinforced concrete lining arch wall.
Description
technical field [0001] The invention relates to underground projects (including railways, highways, underwater rivers, cities and subsea tunnels, underground oil depots, grain depots, fruit and vegetable depots, parking lots, urban underground public pipelines, protective walls of nuclear power plants, civil air defense projects, shaft projects, concealed projects, Bridge pillars, reservoir dams, etc.) in the field of arch walls and inner wall support protection reinforcement components of important infrastructure, specifically a pre-buried ductile iron frame-reinforced concrete composite tunnel wall plate. Background technique [0002] At present, in China, tunnel design and construction are mainly based on the basic principles of the New Austrian Method, especially for underwater waterways, urban subways, and underground pipeline projects. The blasting method design and construction, its core technology is to use a variety of auxiliary technical measures to first strengthe...
