AI Technical Summary

Technical Problem

The existing construction methods of point-supported prefabricated floating plate tracks are cumbersome, resulting in low construction efficiency, and the stress state of the elastic components of the vibration isolator is not intuitive, which is prone to empty hanging, affecting the track state and maintenance efficiency.

Method used

A new construction method is adopted, including foundation measurement and installation, substrate construction, vibration isolator installation surface detection and adjustment, vibration isolator installation, prefabricated floating plate laying and rail installation. By setting the initial heightening gasket and elastic components on the installation surface of the vibration isolator and checking the installation height for adjustment, ensure that the vibration isolator is in a good stress state, and then directly laying the prefabricated floating plate to avoid multiple hoisting.

Benefits of technology

The construction process is simplified, construction efficiency is improved, high-quality construction of the track is ensured, and through intuitive stress status monitoring, the space for post-maintenance adjustment is reduced.

Abstract

The invention provides a point-supported prefabricated floating slab track and a construction method thereof, and the construction method comprises the steps of foundation mark measuring and setting, foundation construction, vibration isolator mounting surface detection and adjustment, vibration isolator mounting, prefabricated floating slab laying, steel rail and buckle fitting mounting and limiting boss construction, due to the fact that the vibration isolator is of the structure that the initial height adjusting gasket is arranged between the base and the elastic assembly, an outer sleeve of the vibration isolator is not arranged in the prefabricated floating slab any more, the force bearing plate is pre-buried at the bottom of the slab, and the structure that the elastic assembly is externally arranged is adopted; in the construction process, the mode that the installation height of each vibration isolator is detected and adjusted firstly, and then the prefabricated floating slab is laid is adopted, so that the situation that the prefabricated floating slab is jacked for multiple times to install and adjust the vibration isolators in a traditional construction method can be avoided, a straight laying type construction method without jacking is formed, and the construction efficiency is improved. The working procedures of the point-supported prefabricated floating slab track are greatly simplified, and the construction efficiency is improved.
