Description

Diameter-changing device for concrete jacking pipe

Technical Field

The application relates to a concrete jacking pipe, in particular to a reducing device for the concrete jacking pipe.

Background

The trenchless engineering technology thoroughly solves the problems of damage to urban buildings, road traffic blockage and the like in pipeline embedding construction, and has obvious advantages in soil stabilization and environmental protection. This is very important for cities with heavy traffic, dense population, numerous ground buildings and complex underground pipelines, which will create a clean, comfortable and beautiful environment for the cities. The pipe-jacking construction is a non-excavation construction method, and is a pipeline burying construction technology without excavation or with few excavations. The pipe jacking construction is that the friction force between the pipeline and the surrounding soil is overcome by means of the jacking force generated by jacking equipment in a working pit, the pipeline is jacked into the soil according to the designed gradient, and earthwork is transported away. After one section of pipe is pushed into the soil layer, the second section of pipe is pushed into the soil layer continuously. The principle is that by means of the thrust of the main top oil cylinder, the pipeline and the relay, the tool pipe or the development machine is pushed into the receiving pit from the working pit through the soil layer and is lifted. The pipeline is buried between the two pits after following the tool pipe or the heading machine. However, during construction operation, due to the fact that pipelines of the same specification have various wall thicknesses, the jacking machine head can only be matched with a fixed wall thickness after being manufactured and cannot be matched with other wall-thickness pipes of the same specification, namely, the jacking machine head cannot be installed in place with pipe sockets of other models, and cannot be jacked. In the engineering, the jacking machine head is manufactured again according to the actual wall thickness provided by a pipeline manufacturer, but the cost is high, the period is long, and the resource waste is caused. Or the actual wall thickness's that pipeline manufacture factory provided pipeline socket is filled or grinding treatment according to the aircraft nose size of advancing of having made, nevertheless so make the pipeline impaired, life can greatly reduced, and the construction process axis of advancing simultaneously deflects easily, need constantly rectify a deviation, influences efficiency of construction and safety guarantee. Therefore, a diameter-changing device for a concrete jacking pipe needs to be found to solve the problems.
