The beam wheel 3 is a finished trolley wheel 18 with a diameter of 5 cm. The beam girder 2 is slidably connected with the longitudinal track 1 through the beam wheel 3, so as to realize the longitudinal movement of the system. The moving trolley 4 has a length, a width and a height of 1 m, 1 m and 0.5 m respectively. The moving trolley 4 is formed by welding a square steel tube with a size of 40*40*4 and then wrapping a 5 mm steel plate outside. A hole with a diameter of 40 cm is formed in the lower part of the moving trolley 4. The moving trolley 4 moves on the beam girder 2 through the trolley traction rope 5, so as to realize the transverse movement of the moving trolley 4. The trolley door 6 is composed of a steel plate with a diameter of 45 cm and a thickness of 1 cm.

[0027] Please refer to Fig. 3 , as a further embodiment of the beam girder: the beam girder 2 is provided with a beam handle 14 at both ends.

[0028] Specifically, the beam handle 14 is a steel pipe with a length of 50 cm, a diameter of 5 cm and a wall thickness of 3.5 mm. By controlling the beam handle 14, the beam girder 2 can be directly moved, and the movement of the beam girder 2 on the longitudinal track 1 can be controlled.

[0029] Please refer to Fig. 1 , as a further embodiment of the moving trolley: the beam girder 2 is provided with a pulley support 15 at the upper end, and the pulley support 15 is provided with a traction rope pulley 16, which cooperates with the trolley traction rope 5.

[0030] Specifically, the pulley support 15 is a steel pipe with a diameter of 5 cm and a wall thickness of 3.5 mm, and the traction rope pulley 16 is a finished product pulley with a diameter of 10 cm. The traction rope pulley 16 guides the trolley traction rope 5 to stably pull the moving trolley 4 to move.

[0031] Please refer to Figs. 1-3 As a further embodiment of the moving trolley: the upper end of the beam girder 2 is provided with a trolley track 17, and the lower end of the moving trolley 4 is provided with a trolley wheel 18, which cooperates with the trolley track 17.

[0032] Specifically, the trolley track 17 is formed by inverting a 5 cm angle steel, and the length is the same as that of the beam. The trolley wheel 18 is a finished product trolley wheel 18 with a diameter of 5 cm. Through the cooperation of the trolley wheel 18 and the trolley track 17, the moving trolley 4 can stably move on the beam girder 2.

[0033] In summary, when the whole device is in use or operation:

[0034] When using the device, the longitudinal track 1 and the beam girder 2 are laid to make the moving trolley 4 work stably. The longitudinal track 1 supports the beam girder 2, and the beam handle 14 is controlled to directly move the beam girder 2, control the movement of the beam girder 2 on the longitudinal track 1, and the beam girder 2 is in sliding cooperation with the longitudinal track 1 through the beam wheel 3, to ensure smooth movement. The beam girder 2 supports the moving trolley 4 and moves together with the moving trolley 4, realizes longitudinal movement of the system, controls the moving trolley 4 in the working area through the trolley traction rope 5, and makes the trolley traction rope 5 stably move under the guidance of the traction rope pulley 16. The moving trolley 4 is pulled by the trolley traction rope 5 to move, and the moving trolley 4 is in cooperation with the trolley track 17 through the trolley wheel 18, and is guided by the trolley track 17 under the pulling of the trolley traction rope 5, so that the moving trolley 4 stably moves on the beam girder 2, realizes the horizontal movement of the system, and controls the omnidirectional movement of the moving trolley 4 in the working area.

[0035] When the flowable concrete is transported, the trolley door 6 is closed to block the center of the lower opening structure of the moving trolley 4, so that the flowable concrete is stored in the moving trolley 4 and transported by the moving trolley 4. When the flowable concrete is poured, the trolley door 6 is adjusted by the door traction rope 7 to expose the lower opening structure of the moving trolley 4, so that the flowable mixture flows out. The moving trolley 4 is controlled to move longitudinally and transversely by the cooperation of the beam handle 14 and the trolley traction rope 5, so that the material is arranged in the appropriate position and enters the string barrel group 8. The material is discharged by the cooperation of the fixed string barrel section 9 and the plurality of detachable string barrel sections 10. During the process, the lowermost detachable string barrel section 10 is controlled by the string barrel traction rope 13, so that the detachable string barrel section 10 drives the upper detachable string barrel section 10 to deflect by its own structure, thereby controlling the extension direction of the entire string barrel group 8. The deep foundation pit can be backfilled at 360° without dead angle, and the flowable mixture can be poured without segregation.

[0036] In all the above-mentioned solutions, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut cooperation connection, bolt or screw connection or other known connection methods, which will not be described one by one. In the above, when it is mentioned that there is a fixed connection, it is preferred to consider welding, although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
