The horizontal support plate 19 is mounted on the side beams of a movable trestle 18. A horizontal support frame 2 is provided at the top of the two sets of vertical support frames 1. The horizontal support frame 2 and the two sets of vertical support frames 1 form a portal frame structure. Both the vertical support frame 1 and the horizontal support frame 2 are hollow structures. A first concrete conveying pipe 4 is provided on one side of the portal frame. The bend of the first concrete conveying pipe 4 is connected by an elbow 5. A pipe support plate 3 is provided at the bottom of the first concrete conveying pipe 4, and the pipe support plate 3 is connected to the side beams of the movable trestle 18.

[0028] A rotating seat 6 is provided at the upper middle part of the horizontal support frame 2. The rotating seat 6 is a hollow structure, which is a common hollow rotating structure. A rotating connecting seat 7 is fitted at the center of the rotating seat 6. A connecting support frame 8 is provided at the upper end of the rotating seat 6. A horizontal frame 9 is provided at the upper end of the connecting support frame 8. A counterweight box 10 is provided at one end of the horizontal frame 9.

The second concrete conveying pipe 11 extends downward to one side of the vertical support frame 1, and the bend of the second concrete conveying pipe 11 is connected by an elbow 5.

[0029] The end of the second concrete conveying pipe 11 is equipped with a concrete hose 12, which makes it easier for workers to control the discharge direction of the concrete.

[0030] Both the upper and lower ends of the rotating connecting seat 7 are connected to transition connecting pipes 17, which are connected to the rotating connecting seat 7 by threaded connection.

[0031] The transition connecting pipes 17 at the upper and lower ends of the rotating connecting seat 7 are respectively connected to the second concrete conveying pipe 11 and the first concrete conveying pipe 4.

[0032] like Figure 2 As shown, the support beams on both sides of the cross frame 9 are welded together by several reinforcing rods 16; a central rod 14 is provided in the middle of the support beams on both sides of the cross frame 9, and inclined steel wire ropes 13 connected to the cross frame 9 are provided on both sides of the central rod 14.

[0033] In this embodiment, in order to improve the strength at the center of the cross frame 9, a steel plate is provided at the center of the cross frame 9, and a circular through hole is reserved on the steel plate so that the second concrete conveying pipe 11 can pass through.

[0035] The mounting flange 702 is fixed on the rotating seat 6. In use, rotating the rotating seat 6 will cause the crossbeam 9 to rotate. During the rotation of the crossbeam 9, the rotating hollow tube 703 will rotate, so that concrete can still be pumped even when the crossbeam 9 is rotating.

[0036] In this embodiment, as Figure 4 As shown, the vertical support frame 1 adopts a rectangular hollow iron frame structure welded from angle iron. In order to improve the stability of the vertical support frame 1, a reinforcing support rod 20 is also provided between the vertical support frame 1 and the horizontal support plate 19.

[0037] During use, on the already completed invert arch filled concrete surface, concrete transport vehicles are parked, and concrete pumping equipment is used to pump concrete through the first concrete delivery pipe 4, which is then lifted to a height by the portal frame, passes through the rotating seat 6 above the portal frame, reaches the second concrete delivery pipe 11, and finally reaches the concrete hose 12. Workers can complete the concrete pouring work at any position of the tunnel invert arch by controlling the concrete hose 12 and the rotating seat 6.
