Embodiment Construction
[0024] The following is attached Figure 1-8 The specific implementation manners of the present invention are further described in detail.
[0025]When this embodiment is in use, the support seat 1 of the experimental device is first placed on a horizontal hard ground, and at this time, the hydraulic jack 2 is adjusted to raise the right end of the settlement simulation box 3 to the angle required for the experiment. 3 The angle pointer 5 fixedly connected to the left side of the lower end surface and the rotating connection part of the support seat 1 on the protruding part of the front side indicates the inclination angle of the settlement simulation box 3 at this time, and then stops the hydraulic jack 2 after the pointer indicates the required angle And make the hydraulic jack 2 keep the original position, now adjust the threaded adjustment rod 18 on the tilt angle adjusting device on the left side of the left inclined plate 11, so that the inclined angle of the inclined pl...
