[0025] Further Figure 1-3As shown, it is worth explaining in detail that in order to be able to adjust the supporting height of the I-shaped plate frame 3 according to the foundation pit body 1 of different depths, a height-adjustable supporting structure 4 is set, including two symmetrically arranged supporting outer plates 41 fixed at the bottom end of the I-shaped plate frame 3, and the movable channels arranged at the bottom ends of the supporting outer plates 41 are slidably connected with movable inner plates 42 with I-shaped cross-sections, and the threaded channels arranged on the movable inner plates 42 are threadedly connected with screws a43, and the top ends of the screws a43 are rotatably connected to the inner top wall of the threaded channels and extend to the top of the supporting outer plates 41, and are fixed with pulleys 44, and a transmission belt 45 is transmission-connected between the two pulleys 44, and a handle a is also fixed to the top extension of one of the screws a43.

[0026] The handle a rotates the screw a43, and the two pulleys 44 are connected by a transmission belt 45, so that the two screws a43 rotate in the same direction. Since the screws a43 are threadedly connected to the movable inner plate 42, the two movable inner plates 42 move up or down synchronously. Figure 2 Visible in.

[0027] Further Figure 1-3 As shown, it is worth explaining in detail that, in order to facilitate the support of the two supporting formworks 2 in the foundation pit body 1 of different widths, a support structure 5 is provided, including a C-shaped seat 51 fixedly connected to the middle part of the outer side of the I-shaped plate frame 3, and the top of the C-shaped seat 51 is rotatably connected to a screw b52, and the top of the screw b52 is fixedly connected to a handle b, and the outer side of the screw b52 is threadedly connected to a movable block 521, and both ends of the movable block 521 are rotatably connected to push-pull rods 53, and the ends of the two push-pull rods 53 that are away from each other are hinged to the top of the support plate 54, and two symmetrically arranged guide strips 55 are fixedly connected to the opposite side walls of the two support plates 54, and the guide strips 55 slide in the guide grooves arranged on the outer side of the I-shaped plate frame 3, and the vertical cross-sections of the guide strips 55 are convex structures.
