Underground pipeline installation centering device for hydraulic engineering construction

Abstract

The invention discloses an underground pipeline installation centering device for hydraulic engineering construction, and relates to the technical field of hydraulic engineering construction. The underground pipeline installation centering device for hydraulic engineering construction comprises a bearing box body; a bearing lifting mechanism is arranged in the bearing box body; a buffering mechanism and a fixing mechanism are arranged on the inner side of the bearing lifting mechanism; a pipe lowering mechanism is arranged above the bearing lifting mechanism; and a supporting mechanism is arranged at the bottom of the bearing box body. According to the underground pipeline installation centering device for hydraulic engineering construction, lower pipe lapping plates are lapped on the two sides of an underground tunnel, constructors can roll an underground pipeline to be butted into a bearing lifting mechanism with the help of the lower pipe lapping plates, so that the operation is simple, labor is saved, the underground pipeline does not need to be hoisted into the underground tunnel with the help of an external machine, the conveying time is saved, the construction efficiency is improved, meanwhile, the construction cost is reduced, vibration generated during connection is relieved, and then a guarantee is provided for the quality of pipeline connection operation.

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 ...

[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 kind of device is inconvenient to move in the tunnel, and it is difficult to meet the requirements of long-distance underground pipeline connection operation. It has poor practicability and is not conducive to promotion and use.
