Supporting frame for preventing tunnel settlement deformation

The utility model provides a supporting frame for preventing settlement deformation of a tunnel, relates to the technical field of tunnel supporting devices, and solves the problems that an existing tunnel anti-settlement supporting frame is tedious in operation and poor in supporting stability and affects the anti-settlement effect during adjustment. Four guide rods are fixedly connected to the tops of the two supporting bottom plates through welding; the tops of the two lower supporting seats are each provided with two main supporting columns, and the outer sides of the two main supporting columns in each set are each provided with a supporting column connecting frame. An upper supporting plate is mounted at the tops of the two groups of main supporting columns; the left side and the right side of each supporting bottom plate are each fixedly connected with three anti-sinking plates. When the device is installed, the length of the supporting column does not need to be adjusted, only the height of the lower
