[0037] The working principle of the present utility model is as follows:

[0038] In the pouring area, the preliminary construction of the roadbed is carried out to ensure that the moving device 1 can move on the ground. By moving the entire trestle device to the construction area, the construction area can be cleared of muck. Then, a steel mesh or invert formwork is laid in the area, and the concrete is transported to different positions in the construction area through the watering device 3 to realize the construction of the roadbed;

[0039] Among them, the moving device 1 can realize the horizontal or vertical movement of the trestle device through the sliding of the horizontal pulley group 15 and the vertical pulley group 16. One end of the horizontal pulley group 15 and the vertical pulley group 16 can be telescopically connected to the main beam 11, and the other end is rotatably provided with pulleys. The rotation directions of the horizontal pulley group 15 and the vertical pulley group 16 are perpendicular to each other. When horizontal and vertical movement is required, the horizontal pulley group 15 or the vertical pulley group 16 is telescoped until the bottom pulley contacts the ground to realize the movement of the trestle device. After the movement is completed, the top rod group 17 moves down to contact the ground, and the horizontal pulley group 15 or the vertical pulley group 16 is retracted to complete the movement of the trestle device. Since a working space 22 is formed between the two bridge plates 2, during the construction process, the working vehicle can move on the bridge plate 2 to clear and transfer the muck in the construction area, improving the practicability of the trestle device;

[0040] After laying the inverted arch formwork, by conveying concrete into the loading trough 32, the concrete successively passes through the loading trough 32, the output pipe 34, and the guiding trough 35, and finally flows to the pouring ground. Among them, the angular position of the guiding trough 35 can be adjusted. Since the guiding trough 35 is connected to the turntable 33, and the turntable 33 is rotatably connected to the sliding plate 31, the angular change of the guiding trough 35 is realized. At the same time, a hydraulic rod 36 is provided at one end of the guiding trough 35 close to the output pipe 34. The two ends of the hydraulic rod 36 are respectively jointed with the turntable 33 and the guiding trough 35. By the telescopic movement of the hydraulic rod 36, the height of the end of the guiding trough 35 away from the output pipe 34 from the ground can be changed, so as to change the position where the concrete flows out of the guiding trough 35, and realize the pouring and conveying of concrete at different positions within the construction area.
