Description

Technical Field

[0001] The utility model relates to a prefabricated pipeline for municipal engineering pipe jacking engineering, belonging to the technical field of municipal engineering. Background Art

[0002] Pipe jacking construction is an underground pipeline construction method developed after shield construction. It does not require excavation of the surface layer and can pass through roads, railways, rivers, ground buildings, underground structures and various underground pipelines. Pipe jacking construction uses the thrust of the main jacking cylinder and the pipeline relay room to push the tool pipe or tunnel boring machine from the working well through the soil layer to the receiving well for hoisting. At the same time, the pipeline following the tool pipe or tunnel boring machine is buried between the two wells, in order to realize the construction method of trenchless laying of underground pipelines.

[0003] The comparison patent document publication number is: "CN220891266U, a prefabricated pipe for a municipal engineering jacking project, wherein the front and rear fixed frames are connected on all sides by connecting rods, the fixed frame and the connecting rods are filled with concrete retaining walls, expansion joint fillers are installed between the concrete retaining walls, the front and rear fixed frames are installed with fixed ears on all sides, and the prefabricated pipes are connected in sequence through the front and rear fixed ears of the fixing frames, rubber sealing gaskets are installed around the outer sides of the front and rear fixed frames, threaded steel is installed inside the concrete retaining walls, and the front and rear ends of the threaded steel are respectively welded to the inner sides of the front and rear fixed frames, a number of arc-shaped clamps are equidistantly tied to the threaded steel, and the threaded steel and the arc-shaped clamps form a concrete retaining wall skeleton."

When the pressure is too high, it is easy to leak after breaking through this seal, which makes the prefabricated pipe less sealed. Utility Model Content
