The invention discloses an assembled stratum stress compensation servo steel frame system for controlling large deformation of a tunnel, comprising: a servo support structure and a servo controller; the servo support structure includes: an annular steel arch frame, which is arranged in the tunnel and installed on the The inner bottom of the tunnel; the servo is arranged between the annular steel arch and the initial support, and one end is connected to the initial support, and the other end is installed to the annular steel arch; the servo controller adjusts the servo according to the deformation of the initial support support of the device. The present invention is a prefabricated formation stress compensation servo steel frame system for controlling large deformation of tunnels, which utilizes the mechanical transfer mechanism and the interaction principle to realize the coordinated bearing of formation-structure, and solves the problem of excessive initial support deformation before the implementation of remedial measures. The problem is that the steel frame is formed by assembling the prefabricated steel, which is fast and convenient to install, simple to operate, convenient to construct, and has a good deformation control effect.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to an assembled stratum stress compensation servo steel frame system for controlling large deformation of a tunnel. Background technique [0002] Deep-buried tunnels are usually constructed by underground excavation. After the tunnel is excavated, the stress and displacement of the surrounding rock must be released. While the surrounding rock can exert its own bearing capacity, it is necessary to use the supporting structure to assist the surrounding rock to bear, and then achieve the stratum-structure. balance between them. The initial support is the first line of defense to assist the surrounding rock to bear the load. It bears the surrounding earth pressure and water pressure. According to previous engineering experience, the settlement deformation of the vault and the deformation of the side wall are generally relatively large. Due to the rheological properties of so...
