Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated pipe segments, in particular to a modular prefabricated pipe segment mould. Background Art

[0002] With the development of domestic transportation systems, the construction of underground urban rails and tunnels through mountains and seas, precast concrete lining segments have been widely used in the construction of modern urban rail transit. Shield tunnel segments have become the main application direction of precast concrete segments. Precast concrete lining segment molds are special equipment for the production of shield tunnel segments. For example, a precast arc-shaped segment forming mold is recorded in the patent with patent announcement number CN220179604U. In the utility model, the column driving mechanism can drive the column to rotate around the vertical axis, so that the operator only needs to stand in one position to complete the fixing of bolts at all positions, which is very convenient; after the concrete slurry is injected into the mold cavity, the swing bracket can be reciprocated around its own axis to make the concrete slurry uniform in the mold cavity and discharge excess gas in the concrete slurry.
