Abstract

The invention belongs to the technical field of bidirectional pretensioning prestressed track slab prefabrication of high-speed railway CRTSⅢ slab ballastless track, and specifically relates to a device and method for detecting deformation of tension beams of CRTSⅢ bidirectional pretensioned prestressed track slabs. It solves the problem of detecting the deformation of the tension beam of the CRTSⅢ bidirectional pretensioned prestressed track slab. A device for detecting the deformation of the tensioned beam of the CRTSⅢ bidirectional pretensioned prestressed track slab includes a tension anchor beam, fixed in the tension The tension jack on the tension anchor beam and the tension beam placed inside the tension anchor beam and parallel to the tension anchor beam, the bottom of the tension beam is fixed, and the two ends of the tension beam are respectively connected and fixed with a tension jack perpendicular to it. Jack, the other end of the tensioning jack is fixedly connected with the tensioning anchor beam, a steel ruler is set on the transverse centerline of the tensioning beam, and a fishing line parallel to the tensioning beam is arranged on the steel ruler, and the tensioning jack oil is corresponding to the tensioning beam. A measuring device is provided at the center of the top.

Description

technical field [0001] The invention belongs to the technical field of bidirectional pretensioned prestressed track slab prefabrication of high-speed railway CRTSⅢ type slab ballastless track, and specifically relates to a device and method for detecting deformation of tension beams of CRTSⅢ bidirectional pretensioned prestressed track slabs. Background technique [0002] CRTSⅢ slab ballastless track is a new ballastless track structure system newly developed in my country with completely independent intellectual property rights. CRTSⅢ pretensioned prestressed concrete track slab is an important part of CRTSⅢ slab ballastless track structure. It is produced in a factory and then laid on site. [0003] In order to ensure that the vertical and horizontal prestressed steel bars in the track slab are stretched to the design value, and at the same time ensure that each prestressed bar is evenly stressed, in addition to the requirements for the tensioning platform, it should have s...
