Abstract

The invention discloses a high-stability axial connecting component, which comprises a middle sleeve, wherein two ends of the middle sleeve are independently connected with an end part sleeve; the surface of each end part sleeve is sheathed with an anti-skidding sleeve; the end part of each anti-skidding sleeve is provided with an expansion head; the middle sleeve is internally symmetrically provided with two groups of connecting rod mechanisms; the left end and the right end of each connecting rod mechanism are connected with a connecting shaft; the connecting shaft can slide in the end partsleeve; the end part of the connecting part is outwards extruded to form an extrusion part; and the extrusion part is embedded in the expansion head. Compared with traditional bolt locking, the devicerotates a locking bolt to drive the connecting rod mechanisms and the connecting shaft to move in sequence, the extrusion part on the end part of the connecting shaft is used for outwards extruding the expansion head to deform so as to enhance connection intensity between the connecting component and pipe pieces, and finally, the connection intensity between two adjacent pipe pieces can be improved.

Description

technical field [0001] The invention relates to a highly stable axial connection assembly. Background technique [0002] At present, the existing shield tunnels are generally spliced ​​by prefabricated segments of several specifications. When such segments are prefabricated, the connecting bolt holes need to be positioned on the formwork in advance so that the prefabricated segments can be placed in the shield tunnel. When tunneling, special connecting bolts are used for circumferential and longitudinal connection and fastening to form a complete concrete pipeline. However, in the specific use process, it is necessary to solve the problem of circumferential and longitudinal splicing between segments. The present invention solves the problem of connection between longitudinally adjacent segments. The existing segment assembly has slow construction speed and labor intensity. Large, low connection strength, low shear resistance and so on. Contents of the invention [0003] ...
