Underground pipeline installation centering device for hydraulic engineering construction

Abstract

The invention discloses an underground pipeline installation centering device for hydraulic engineering construction, and belongs to the technical field of hydraulic engineering construction. The underground pipeline installation centering device for hydraulic engineering construction comprises a pipeline A, wherein a pipeline B is arranged at the right side of the pipeline A; a sliding groove is formed in the right portion of the pipeline A; a fixing ring is arranged in the sliding groove; a plurality of bolt holes are formed in the fixing ring; bolt rods are arranged in the bolt holes; the outer side of the left end of the pipeline B is sleeved with a connecting pipe; a wide-opening groove is formed in the right side of the connecting pipe; a limiting ring is arranged in the connecting pipe; a mounting plate is arranged below the pipeline A; a plurality of sleeves are arranged below the mounting plate; springs A and ground plugs are arranged in the sleeves; two arc-shaped plates are symmetrically arranged above the mounting plate; a threaded rod is arranged below the arc-shaped plates; two sleeve rings are symmetrically arranged on the threaded rod; sliding rods are connected to the upper portions of the sleeve rings; and the sleeves are connected to the upper portions of the sliding rods. By using the underground pipeline installation centering device, a user can conveniently install a pipeline.

Description

technical field [0001] The invention relates to the technical field of water conservancy project construction, in particular to an installation centering device for underground pipelines used in water conservancy project construction. Background technique [0002] The construction of water conservancy projects needs to excavate tunnels and install underground pipes in them. When installing underground pipes, centering treatment is required to ensure that the underground pipes are connected correctly. Some underground pipe centering devices have complicated centering steps and poor practicability. And lack of shock absorption measures, the vibration generated when the underground pipeline is connected will cause some interference to the connection operation, and when the underground pipeline is sent into the tunnel, it needs to use cranes and other equipment to complete the operation, which affects the construction efficiency and increases the construction cost. This type of ...

AI Technical Summary

Problems solved by technology

Although the device has many beneficial effects, the following problems still exist: during the use of the device, due to the frictional contact between the device and the ground, it is easy to be disturbed by external force, which affects the efficiency of pipeline installation

In addition, existing pipe centering devices cannot center pipes of different sizes
