AI Technical Summary
In existing technologies, the construction of drainage ditches for high-speed railway subgrades suffers from high construction costs, slow construction progress, and difficulty in quality control. Defects in mechanical material placement require waiting for the concrete to solidify before they can be remedied, which prolongs the construction time.
A roadbed drainage ditch slipform machine was designed, comprising an operating platform, an outer edge forming section, a winch, a hopper, a discharge port, and a die-casting section. It allows construction personnel to perform real-time inspection and repair during the material placement process and is equipped with a vibrator and rollers to ensure uniform concrete distribution and quality control.
It enables real-time repair of defects during construction, reduces secondary construction, improves construction efficiency and quality control, and lowers construction costs.
