In order to ensure the stability of the bottom plate and the side top, a fixed mold is required. However, in order to ensure the stability of the fixed mold for the side top, a baffle bar is required to fix it. The baffle bar needs to be inserted into the bottom plate, thereby destroying the integrity of the bottom plate and requiring subsequent repair. Therefore, a mirror concrete fixed mold for the bottom plate of a horseshoe-shaped tunnel construction is needed to solve the above problems. Utility Model Content

[0025] The supporting mechanism 5 includes a plurality of supporting frames 501 slidably connected in the first frame 1 and the second frame 2. Two sets of sleeve rods 502 are symmetrically arranged on opposite sides of the two supporting frames 501 in the first frame 1 and the second frame 2 respectively. Two sets of connecting rods 503 are movably connected in each set of sleeve rods 502. Two sets of fastening knobs 504 are symmetrically installed on the surface of each set of sleeve rods 502.

This structure can be adjusted according to tunnels of different specifications, greatly increasing the scope of application.

[0027] When in use, the first frame 1 and the second frame 2 together with the fixed mold body 7 at the bottom of the two are placed on the top of the base slab concrete, then all the fastening knobs 504 are loosened, and the support frame 501 is pulled to move outward and abut against the mold surface for fixing the side top, thereby ensuring the stability of the side top fixed mold, eliminating the trouble of using a baffle and effectively ensuring the integrity of the base slab concrete.

[0028] Embodiment 2, by Figure 1-7 It is shown that, on the basis of Example 1, a regional adjustment mechanism 6 is provided in the support mechanism 5, and the regional adjustment mechanism 6 includes two groups of cross frames 601 slidably connected in the support frame 501, and sliders 602 are installed at both ends of each group of cross frames 601, and two groups of screws 603 are threadedly connected in each group of sliders 602, and multiple groups of partitions 604 are commonly connected to the bottom of the two groups of cross frames 601, and an adjusting screw 605 is rotatably connected in each group of partitions 604, and two groups of sleeves 606 are threadedly connected on the surface of the adjusting screw 605, and two groups of fixing rods 607 are slidably connected in each group of partitions 604, and a protrusion 608 is installed at the bottom end of each group of fixing rods 607 and the top of each group of sleeves 606, and a spring 609 is sleeved on the surface of each group of fixing rods 607.
