Description

Technical Field

[0001] The present application relates to the technical field of pipeline support, and in particular to a sliding pier suitable for underground pipelines. Background Art

[0002] The integrated pipe gallery, also known as the underground urban pipeline integrated corridor, is to build a tunnel space underground in the city, concentrate various underground engineering pipelines in it, and implement unified planning and unified management. The construction of pipelines in the corridor is an indispensable part of the construction of the integrated pipe gallery, and the pier is an indispensable component in the construction of pipelines in the corridor. The pier refers to the pedestal built to prevent the displacement of the joints of water pipe fittings caused by the water pressure in the pipe. Concrete piers are the most commonly used.

[0003] The patent document with the published announcement number CN220131927U provides a steel sliding support for corridor pipelines. It includes a basic support and a pipe clamp; the pipe clamp is connected into a ring by multiple arc-shaped pipe supports; the basic support includes multiple rows of support rods in the same direction as the pipeline axis, and the top of the middle row of support rods is a support groove that matches the shape of the connection position of the pipe clamp; the support rod can be adjusted in height individually. The overall curvature formed by connecting multiple arc-shaped pipe supports can be adjusted according to the size of the pipeline, and can be matched with pipelines of different diameters and curvatures.

[0004] The advantage of the above device is that it can slide and be assembled on site to achieve mass production, but its key component, the arc-shaped steel plate, is welded to the partition after being rolled and pressed. The degree of deformation during the process is difficult to control, and it is difficult to overlap well with the underground pipeline it supports. In addition, the height of the U-shaped steel plate is fixed, making it difficult to adjust the height of the entire pier. The height of the pipeline supported by the adjacent pier is also difficult to adjust, making it difficult to splice the pipeline and difficult to control the construction accuracy.
