The embedded channel is the component supporting the catenary in the construction of high-speed railway, which is used in the tunnel engineering of high-speed railway. The channel is embedded into the concrete to fix the catenary, communication signal and power equipment. The high-speed railway has high requirements on the compressive capacity and corrosivity of the channel. The channel with zinc spot has hidden danger. The support force of the rusty channel is insufficient. The catenary may fall on the running train due to the insufficient support of the channel.
