Embodiment
The device of the utility model is used for Shanghai S7 highway new construction, actively visits in the full precast assembly technical field of bridge
Rope makes a breakthrough in the fields such as the high block construction of bent cap and buried anchor technique, abutment precast assembly technology.
Large-scale bent cap is divided into several small-sized segments by the technology, matches prefabricated construction, and Mosaic face uses epoxy glue seam, connects
Slit formula is the vertical piece of corbel type.The miniaturization of segment is readily transported and lifts；Matching prefabricated construction may insure seam
It is uniformly closely connected；Mosaic face can guarantee the quality and rapid construction of seam using performance of epoxy bonded.
