  • Publication number: 20240141785
    Abstract: A zonal bolt-grouting support device and method for cataclastic rock mass large deformation of a high-stress tunnel, the method includes: drill holes in surrounding rock of a tunnel against a tunnel face after rock mass excavation, install high-strength prestressed anchor members, apply a preload to anchor bolts when expansion anchoring agent is fully expanded and has a certain strength, and zonally grout the surrounding rock after stress adjustment. The high-strength prestressed anchor member comprises an anchor bolt, an expansion anchor agent, a decoupling material, a grouting device, a reverse anti-skid device, etc. The grouting device consists of a shallow grouting steel pipe, a deep grouting steel pipe and a grouting stop valve, and the grouting steel pipe is arranged side by side with the anchor bolt in a drill hole. The technical proposal of the invention effectively inhibits the large deformation of a cataclastic rock mass.

  • Patent number: 7957495
    Abstract: The method obtains an interference detection result by detecting sampled digital signals in real time in a transform domain, then maps the interference detection result into an interference suppression pulse function on the basis of a unit noise pulse function, and carries out interference suppression filtering in the transform domain according to the interference suppression pulse function. The present invention is capable of detecting narrowband interference such as monotone, frequency modulation, and phase modulation interferences in a receive channel adaptively in real-time, and suppressing the interference adaptively according to the quantity, energy and bandwidth of the interference, so as to reduce the influence of the interference. Therefore, the present invention may enhance robustness of the communication system against interference. Moreover, the present invention does not need multiple notch devices, costs low and may be implemented simply and reliably.
