Description

A frame-type track foundation Technical Field

[0001] This utility model relates to a frame-type track foundation. Background Technology

[0002] Currently in China, dynamic track scales or dynamic overload / off-center load detection devices are required to weigh and inspect the loading capacity and quality of freight cars in operation. To ensure detection accuracy, high requirements are placed on the stability and rigidity of the track foundation in the installation section. Previous practices have involved using monolithic concrete foundations or custom-made sleepers connected together to form a single foundation. Monolithic concrete foundations involve excavating a pit on the track bed, laying reinforcing steel, pouring concrete, and curing. Custom-made sleepers (rectangular in shape) are pre-made with embedded steel structural components. These sleepers are then transported to the installation location, replacing existing ordinary sleepers (such as concrete sleepers), and finally connected into a single frame using connectors. All these methods suffer from drawbacks such as long construction time, significant disruption to train operations, and poor economic efficiency. Summary of the Invention
