DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] See also Figures 1 to 9, a rock and soil foundation pit slope support plate, includes a base, a first rotating rod and a support plate body, one side of the surface of the base is fixedly connected to the first rotating rod, the surface of the first rotating rod is rotatably sleeved with the support plate body, the inner wall surface of the base is rotatably connected to the first screw, the surface of the first screw is threadedly sleeved with a movable plate, the bottom surface of the movable plate is symmetrically fixedly connected to a limited slider, the limited slider and the base are slidably connected, the surface of the movable plate is symmetrically fixedly connected to a first U-shaped seat, the inner wall surface of each first U-shaped seat is rotatably connected to a first threaded cylinder, the surface of the support plate body is slidably connected to an extension plate, the surface of the extension plate is fixedly connected to a docking plate, the surface of the docking plate is symmetrically fixedly connected to a second U-shaped seat, the inner wall surface of each second U-shaped seat is rotatably connected to a second threaded cylinder, and a support rod is threadedly connected between the first threaded cylinder and the second threaded cylinder.

[0036] The surface of the extension plate is symmetrically fixedly connected with threaded columns, the surface of each threaded column is threadedly connected with an adjusting nut, each threaded column is inserted into the surface of the support plate body, and the threaded column and the support plate body are slidably connected.

[0037] The side surface of the docking plate is symmetrically fixedly connected with a second sliding block, the second sliding block is inserted into the surface of the supporting plate body, and the second sliding block is slidably connected to the supporting plate body.

[0038] Telescopic springs are equidistantly fixedly connected between the extension plate and the support plate body.

[0039] One end of the first screw rod extends to the outside of the support plate body and is fixedly connected to a hand wheel arranged on the outside of the support plate body, and a fastening bolt is threadedly connected to the surface of the hand wheel.

[0040] The working principle of this embodiment is as follows: when using this type of protective support plate, first transfer the support plate device as a whole to the inside of the foundation pit, and then adjust the base. After the base is adjusted, the sheath can be loosened in turn to expose the pointed pins, and then the base can be fixed to the inside of the foundation pit by the pointed pins, thereby improving the connection reliability between the base and the foundation pit and ensuring stability during the support process;

[0041] Then, the restriction on the support plate body is released, and the support plate body is rotated so that the support plate body is placed on the slope surface of the slope. Then, the construction workers stand on both sides of the support plate body to observe whether the length of the support plate body meets the support length of the slope. If the length of the support plate body is shorter, the two workers can rotate the adjusting nut at the same time so that the adjusting nut releases the limit on the threaded column. At this time, the extension plate can move outward in the support plate body under the elastic force of the telescopic spring (the telescopic spring is in a compressed state in the initial state) until the length meets the requirement. Then, the position of the extension plate is kept stationary, and the adjusting nut is re-tightened to limit the position of the extension plate, thereby completing the adjustment of the support length of the support plate body. Then, the length of the support rod is adjusted, and then the support rod is respectively connected to the first threaded cylinder and the second threaded cylinder, so that the support plate body can be initially supported.

[0042] During this process, observe the degree of fit between the support plate body and the slope. When the gap between the support plate body and the slope is large, it means that the inclination of the support plate body is not enough. At this time, loosen the fastening bolts and then turn the hand wheel. The rotation of the hand wheel will drive the first screw to rotate, and the rotation of the first screw will drive the movable plate to move, so that the support angle of the support plate body can be adjusted through the support rod to meet different slope support requirements and has a wide range of applications.
