A support structure is installed on the upper wall surfaces of the two load-bearing frames 3, and a load-bearing structure is installed on the inner wall surfaces of the two load-bearing frames 3. A support structure is installed on the upper end surface of the support structure. Four guide rods 4 are installed in the mobile frame 1, and guide wheels 5 are respectively installed on the outer end surfaces of the four guide rods 4; the support structure includes: a number of load-bearing rods 6, a number of cross beams 7, a number of inclined beams 8, a number of support screws 9 and a number of support load-bearing seats 10; the number of load-bearing rods 6, the number of cross beams 7 and the number of inclined beams 8 are respectively connected by a disk buckle type. A number of support screws 9 are respectively installed on the lower end surfaces of the number of load-bearing rods 6, and a number of support load-bearing seats 10 are respectively installed on the lower wall surfaces of the number of support screws 9; the load-bearing structure includes: a number of hydraulic cylinders 11, a number of threaded sleeves 12, a number of load-bearing screws 13 and a number of auxiliary load-bearing seats 14; the number of hydraulic cylinders 11 are respectively installed on the inner wall surfaces of the two load-bearing frames 3, the number of threaded sleeves 12 are respectively installed on the upper wall surfaces of the two load-bearing frames 3, the number of load-bearing screws 13 respectively pass through the two load-bearing frames 3 and are installed in the number of threaded sleeves 12, and a number of auxiliary load-bearing seats 14 are respectively installed on the lower wall surfaces of the number of load-bearing screws 13.

[0020] Please refer to Figure 1 , a number of structural reinforcing ribs 21 are installed between the number of threaded sleeves 12 and the two load-bearing frames 3. In this embodiment, the stability of the two load-bearing frames 3 can be enhanced by the number of structural reinforcing ribs 21.

[0021] Please refer to Figure 3 , an anti-slip pad can be installed on the lower wall surface of the number of auxiliary load-bearing seats 14. In this embodiment, the friction with the ground can be increased by installing the anti-slip pad, and the stability can be improved.

[0022] In this embodiment, when several load-bearing rods 6 are moved to the construction site, the operator starts several hydraulic cylinders 11. The several hydraulic cylinders 11 drive the built-up disk buckle scaffold to move upward through two load-bearing frames 3 until the I-beam 23 supports the top formwork of the culvert. At this time, the operator stops the several hydraulic cylinders 11, and the several moving units 2 are separated from the ground. At this time, the operator rotates several load-bearing screws 13 around several threaded sleeves 12 respectively, and drives several auxiliary load-bearing seats 14 to descend through the several load-bearing screws 13 until the several auxiliary load-bearing seats 14 support the ground, bearing the pressure for the several hydraulic cylinders 11 to prevent the disk buckle scaffold from collapsing when the several hydraulic cylinders 11 are damaged.

[0023] Specifically, the operator builds several load-bearing rods 6, several cross beams 7 and several diagonal beams 8 in a disk buckle manner on two load-bearing frames 3 to form a disk buckle scaffold. Then, the operator holds several load-bearing rods 6 and pushes forward, driving the moving frame 1 to move forward through several moving units 2. When the several load-bearing rods 6 move to the construction site, four guiding wheels 5 are used to ensure the linear movement of the several moving units 2, increasing the construction accuracy. When the several load-bearing rods 6 move to the construction site, the operator starts several hydraulic cylinders 11. The several hydraulic cylinders 11 drive the built-up disk buckle scaffold to move upward through two load-bearing frames 3 until the I-beam 23 supports the top formwork of the culvert. At this time, the operator stops the several hydraulic cylinders 11, and the several moving units 2 are separated from the ground. At this time, the operator rotates several load-bearing screws 13 around several threaded sleeves 12 respectively, and drives several auxiliary load-bearing seats 14 to descend through the several load-bearing screws 13 until the several auxiliary load-bearing seats 14 support the ground, bearing the pressure for the several hydraulic cylinders 11 to prevent the disk buckle scaffold from collapsing when the several hydraulic cylinders 11 are damaged. Finally, several support screws 9 are rotated respectively to drive several support load-bearing seats 10 to move downward until the several support load-bearing seats 10 contact the ground to support the disk buckle scaffold, further reducing the pressure of the several hydraulic cylinders 11.

[0024] Embodiment 2, please refer to Figure 4 , the support structure includes: several load-bearing hinge seats 15, several spring shafts 16, several limit sleeves 17, several auxiliary grips 18, several guide rods 19, several positioning sleeves 20 and several limit grooves 22; several load-bearing hinge seats 15 are respectively installed on the outer wall surfaces of several load-bearing rods 6, several spring shafts 16 are respectively installed on the inner wall surfaces of several load-bearing hinge seats 15, several limit sleeves 17 are respectively sleeved on the outer wall surfaces of several spring shafts 16, several auxiliary grips 18 are respectively installed on the lower end surfaces of several limit sleeves 17, several guide rods 19 are respectively installed on the upper end surfaces of several load-bearing rods 6, several positioning sleeves 20 are respectively sleeved on the upper ends of several guide rods 19 and are threadedly connected with several guide rods 19, and several limit grooves 22 are respectively opened on several load-bearing rods 6.

[0025] Please refer to Figure 1, the upper wall surfaces of several positioning sleeves 20 are respectively installed with I-beams 23. In this embodiment, the box culvert top form is supported by the I-beams 23.

[0026] In this embodiment, by clamping several limit sleeves 17 in several limit grooves 22, the positions of several guide rods 19 can be quickly adjusted. Then, by rotating several guide rods 19 to rotate several positioning sleeves 20, the positions of the positioning sleeves 20 can be precisely adjusted, realizing the quick and accurate adjustment of the height of the positioning sleeves 20.

[0027] Specifically, when the operator installs several I-beams 23, first hold several auxiliary grips 18 on the load-bearing rod 6 and drive several limit sleeves 17 to rotate outward around several spring shafts 16 respectively. Then, the operator uses the other hand to hold several guide rods 19 and pull them out along the load-bearing rod 6. When the position is appropriate, the operator releases the hand holding several auxiliary grips 18, and several spring shafts 16 reset, driving several limit sleeves 17 to insert into the corresponding several limit grooves 22. At this time, the guide rods 19 cannot move in the load-bearing rod 6. Then, the operator rotates the positioning sleeve 20 around the guide rod 19 to make the positioning sleeve 20 move up and down along the guide rod 19 for fine adjustment. When several positioning sleeves 20 are adjusted, the I-beams 23 can be inserted into several positioning sleeves 20 to complete the installation.
