Embodiment Construction

[0034] A method for detecting deformation of CRTSⅢ bidirectional pretensioned prestressed track slab tensioning pedestal. The specific steps are as follows: 1) Install a dial gauge fixing bracket on the inner side of the regular quadrilateral frame anchor beam, and the dial gauge fixing bracket is set on On the concrete ground outside the frame anchor beam, the fixing frame should be set up stably and not in contact with the frame anchor beam. 5 evenly arranged on one side of the frame anchor beam, a total of 20, and the stability should be checked;

[0035] 2) Install all prestressed tendons and connectors;

[0036] 3) Install the dial indicator to the dial indicator fixing frame, check the installation position and stability, take the reading and make a record;

[0037] 4) According to the tensioning procedure of the first tensioning plate, pre-tighten the fixed end according to 30% of the tensioning force;

[0038] 5) After the 30% pre-tightening process is completed, stop...

Abstract

The invention belongs to the technical field of CRTSIII type platy ballastless track bi-directional pre-tensioning method prestress track boards of a high-speed rail and particularly relates to a deformation detection method for a tension table base of the CRTSIII type bi-directional pre-tensioning method prestress track board. The effect of detecting deformation of the tension table base of the CRTSIII type bi-directional pre-tensioning method prestress track board is achieved. The method is used for detecting deformation of the tension table base, the influence on the deformation of the tension table base from effective prestress is determined during control over the prefabricating technical process of the CRTSIII type platy ballastless track bi-directional pre-tensioning method prestress track boards, the strength and the flexural rigidity of each installed tension beam need to be verified, and therefore the tension quality of prestressed tendons of the track board can be ensured.

Description

technical field [0001] 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 deformation detection method for CRTSⅢ bidirectional pretensioned prestressed track slab stretching pedestal. 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 longitudinal and transverse 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, the tensioning platform should have sufficient strength, rigidity and stability, and long...
