AI Technical Summary

Technical Problem

The existing precast box girder end anchoring construction is inefficient, and the quality of concrete pouring cannot be guaranteed, which affects the progress of the project.

Method used

An anchor sealing device for precast box girder is adopted, including a lifting platform and an anchor sealing machine. The anchor sealing machine is equipped with a pressure plate and a transition plate that can move linearly, a vibrator and a concrete inlet. The concrete is pressurized and vibrated by a hydraulic or electric linear actuator, and the anchor hole is sealed by a cover to achieve rapid compaction of the concrete.

Benefits of technology

It improves the uniformity and density of concrete, reduces the difficulty of operation and labor intensity, ensures a tight bond between concrete and beam, reduces appearance defects, meets appearance requirements, and eliminates the need for manual application of fine mortar.

Abstract

The application provides a prefabricated box girder anchor hole sealing device, which comprises a lifting platform, and a sealing anchor machine is arranged on the lifting platform. The sealing anchor machine comprises a linearly movable pressing disc and a transition disc. A plurality of vibrating rods are arranged on the transition disc in the circumferential direction. A plurality of through holes are arranged on the pressing disc. Each vibrating rod penetrates through each through hole of the pressing disc. The pressing disc and the transition disc are relatively movable. The problem that the pouring quality of the prefabricated box girder end sealing anchor cannot be guaranteed is solved.
