In the process of conveying the pipe to a hydraulic reclamation area, a plurality of pipelines are required to be connected, in the process of connecting the pipelines reaching a destination, the pipelines are not all connected in a straight way, for the reason of topography, an elbow joint is often required to butt joint pipelines at two ends when the pipelines are connected at a corner or a climbing, and when a plurality of hydraulic reclamation elbow joints exist, for example, the Chinese patent No. CN114593310A discloses an elbow joint with a wear-resistant lining and a manufacturing method, an inlet end of an elbow body is sleeved with an inlet liner pipe, and an outlet end of the elbow body is sleeved with an outlet liner pipe; the inlet end of the bent pipe body is sleeved and fixed on the first pipeline, and the lining pipe is aligned with the first pipeline; the outlet end of the bent pipe body is sleeved and fixed on the second pipeline, and the inner lining pipe is aligned with the second pipeline; one end of the lining pipe, which is close to the inlet end of the bent pipe body, is a positioning section I, and one end of the lining pipe, which is far away from the inlet end of the bent pipe body, is an antiwear section I; an arc notch I is formed in one side of the wear-resistant section I, which faces the outlet end of the bent pipe body; the lining pipe comprises a positioning section I and an abrasion-resistant section II, and the abrasion-resistant performance of the elbow body is greatly improved and the service life of the elbow joint is prolonged by adding the lining pipe and the lining pipe.
However, in the field of elbow joints for hydraulic filling and conveying, the wear-resistant lining can reduce the loss at the elbow joints, but plays a role of necking, so that the pipeline vibration of a greater degree is caused, and the phenomenon of 'shake of vehicles' is seriously caused.
