Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of segment mould, especially to a mould capable of producing self-rubbed segments. BACKGROUND

[0002] The segment mould is a special concrete precast mould for tunnel segment production, which is usually composed of a bottom plate, four side plates and two upper covers. These moulds are made of mould steel to ensure high precision and long-term durability. The segment is the main assembly component of shield construction and the outermost barrier of the tunnel, which bears the resistance to soil pressure, groundwater pressure and some special loads. The quality of the shield segment directly affects the overall quality and safety of the tunnel and affects the waterproof performance and durability of the tunnel.

[0003] The existing segment mould is connected by bolt fastening through the turning of the end mould close to the side mould. The use of bolt connection increases the workload and time and effort of the mould closing and opening process, which affects the production efficiency of the segment manufacturing line and increases the construction cost.

[0004] The existing patent (publication number: CN220362748U) discloses a segment mould, which includes a middle mould, two end moulds movably installed at both ends of the middle mould and two side moulds movably installed at both sides of the middle mould. Each of the two side moulds is provided with at least one magnetic box for fixing the side mould and the middle mould. Each of the two end moulds is provided with a fastening assembly for fixing the end mould and the middle mould. The end mould and the side mould are provided with a positioning structure. It first operates the fastening assembly to fix the two end moulds and the middle mould, then operates the side mould to accurately reach the mould closing position through the positioning structure, uses the magnetic attraction force generated by the magnetic box of the side mould to the middle mould to make the two side moulds respectively adsorbed on both sides of the middle mould, and the side mould does not use the traditional bolt connection. The positioning effect provided by the threaded hole in the threaded connection mode is replaced by the positioning structure to guide the magnetic box to accurately adsorb the side mould at the mould closing position, which has the effect of improving the mould closing efficiency of the segment mould.

[0005] In view of the above problems, the scheme given in the existing patent replaces the positioning effect provided by the threaded hole in the threaded connection mode with the positioning structure, which has the effect of improving the mould closing efficiency of the segment mould. However, the inner arc of the segment needs to be rubbed during the production of the shield segment, so that the secondary pouring can be realized in the later period. The produced segment cannot have the rubbing effect, which leads to the need for further processing in the later period, which is troublesome. SUMMARY
