[0032] The outer surface of the L-shaped pipe 203 is fixedly connected with a sealing ring 5, and the bottom end of the sealing ring 5 is fixedly connected to the top end of the storage tank 201. The sealing ring 5 can seal the L-shaped pipe 203 and the storage tank 201, effectively preventing leakage during the concrete transportation process;

[0033] The outer surface of each hydraulic cylinder 213 is fixedly connected with a dustproof housing 8, and the upper surface of each dustproof housing 8 is fixedly connected to the bottom end of the fixing frame 1.

[0039] The specific implementation method of this embodiment is as follows: first, the delivery pipeline 202 is connected to the concrete delivery pump on the external concrete transport vehicle. When it is necessary to pour the pile foundation of the large-span rigid skeleton arch bridge, the concrete in the concrete transport vehicle is first delivered to the delivery pipeline 202 through the concrete delivery pump. The concrete delivery pump continuously delivers the concrete along the pipeline by means of a piston or extrusion. During the pouring of the large-span rigid skeleton arch bridge, it can deliver the concrete from the mixing station to the pouring position over a long distance. For some arch bridge parts that are higher than the ground or far away from the concrete mixing site, the delivery pump can push the concrete over at a certain pressure, and can deliver a large amount of concrete in a relatively short time. The concrete is poured into the L-shaped pipe 203 to ensure the continuity of the pouring construction, which helps to improve the construction progress of the entire arch bridge. The L-shaped pipe 203 is then transported to the L-shaped pipe 203. The inner lining layer of the L-shaped pipe 203 is made of wear-resistant rubber material, which can effectively reduce the wear and blockage of the pipe wall and ensure the quality of concrete transportation. The internal reinforcement layer is composed of multiple layers of steel wire and epoxy resin and other materials, which can withstand high pressure and tension to ensure that no cracks or breaks occur during the transportation of concrete. The outer surface is made of natural or synthetic rubber material, which has multiple properties such as anti-aging, anti-corrosion and anti-ultraviolet radiation, ensuring the durability and service life of the conveying pipe. The concrete is then transported to the storage tank 201 and then discharged through the funnel 207. The concrete falls into the discharge pipe 208 and is then discharged downward, so that the pile foundation of the large-span rigid skeleton arch bridge can be poured. At the same time, the output end of the driving motor 206 is rotated to drive the rotating rod 210 inside the bearing 209 to rotate, thereby driving the spiral stirring rod 211 inside the storage tank 201 to rotate, thereby continuously stirring the concrete in the storage tank 201, so that the concrete inside the storage tank 201 is always kept in a uniform state, thereby enhancing the applicability of the device and avoiding the long length of the large-span rigid skeleton arch bridge pile foundation, which makes it difficult to pour the middle part, and when the concrete is transported to the storage tank 201, the concrete in the storage tank 201 is continuously stirred. When the concrete in the vehicle is transported to the middle part of the pile foundation of the large-span rigid skeleton arch bridge, the concrete inside the concrete pouring pipe is prone to agglomeration, the pouring is not uniform, and the pouring quality is poor, which can easily lead to reduced quality and reduced service life of the large-span rigid skeleton arch bridge. In addition, during the pouring process, the telescopic end of the hydraulic cylinder 213 is extended to drive the sliding plate 204 to move downward, thereby pulling one end of the telescopic pipe 212 to move downward, and the telescopic pipe 212 can be extended downward, which is convenient for the precise pouring of concrete in the storage tank 201, and effectively prevents the concrete from spraying outward during the pouring process, resulting in waste of concrete resources and pollution of the external environment.
