Abstract

The invention relates to the technical field of underground engineering settlement deformation observation, and discloses a convenient-to-install real-time tunnel stratum settlement detecting device.The device comprises an initial support steel frame, a tunnel beam is fixedly connected to the outer side of the initial support steel frame, the middle portion of the initial support steel frame is sleeved with anchor rods, and snap rings are fixedly connected to the ends, close to the top of the initial support steel frame, of the anchor rods. The convenient-to-install real-time tunnel stratum settlement detecting device has the advantages of being convenient to install through installation bases, second springs, clamping plates, buffering pads and adjusting bolts; the direct clamped connection with the initial support steel frame can be achieved through U-shaped clamping grooves formed in the installation bases, the initial support steel frame is clamped and fixed through the adjustingbolts and the clamping plates, and the buffering pads can fill cooperation gaps of the clamping plates and the initial support steel frame so that the clamping plates can fully fit the initial supportsteel frame; the installation bases and the initial support steel frame have a certain buffering amount through the second springs, and the influence of excessive impulses on the observation of pressure boxes is avoided.

Description

technical field [0001] The invention relates to the technical field of underground engineering settlement deformation observation, in particular to an easy-to-install real-time tunnel stratum settlement detection device. Background technique [0002] With the development of industrial technology, tunnel excavation technology is becoming more and more mature. Most of the tunnels pass through rocky mountains. In the rock-soil medium, engineering geological conditions and hydrogeological conditions are complex and have many uncertainties. The increase of the operation period or other specific factors will lead to excessive settlement deformation and secondary damage. Tunnels generally use natural foundations, and the settlement deformation is relatively large, and it lasts for many years or even decades, especially in soft soil areas. Perform real-time monitoring. [0003] The structure of tunnel settlement monitoring devices in the prior art is relatively complicated. Some of...
