Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pipe segment prefabrication, in particular to a new CT pre-embedded connector fixing device for a tunnel pipe segment. Background Art

[0002] In the current tunnel construction, the shield machine is used to dig the tunnel, while the segment assembly machine is responsible for splicing the prefabricated segments one by one into a ring structure. During the prefabrication process of the tunnel segments, the connectors need to be installed on the mold end plates through bolts and fixings.

[0003] However, the current fixing method has many limitations: First, the poor accuracy of the fixing position makes the prefabricated segments extremely easy to be damaged when assembled in the tunnel. Secondly, the poor sealing of the fixing device makes it easy to leak slurry when pouring the segments, which in turn causes the connectors to stick together, and the concrete in the inner cavity of the connectors is difficult to clean, seriously affecting the assembly of the segments. Finally, during the pre-embedded installation of the connectors, multiple people are required to work together, which is time-consuming and labor-intensive. In addition, the connectors are installed from the inner cavity of the mold after the steel cage is placed, and the space is small, resulting in a long installation time. For this reason, a new CT pre-embedded connector fixing device for tunnel segments is proposed. Utility Model Content
