The invention belongs to the field of railway construction equipment and particularly relates to a high-frequency vibrating cart for high-speed railway turnout area roadbed concrete. The invention mainly solves the problems that mid extraction and compacting are difficulty realized, the vibrating efficiency is low and the like when an existing conventional flexible shaft type vibrating rod is usedfor performing low-slump and long-life cast-in-place concrete operation in a turnout area. The high-frequency vibrating cart matched with long-life cast-in-place concrete is optimally selected and isassisted with a spring balancer, a cart body framework and a walking system to reduce the labor intensity of workers on the basis of ensuring the flexibility of the vibrating operation; and meanwhile, the problems that incomplete vibration and the like occur when a traditional manual vibrating mode is adopted are effectively avoided. The high-frequency vibrating cart is beneficial to realizing scale application of long-life concrete in a high-speed railway turnout area, remarkably improves the freeze thawing cycle breaking resistance, the cracking resistance and the peeling pulverization resistance of the turnout area roadbed concrete, and effectively ensures the long-term durability of a turnout area ballastless track. Besides, the equipment has the advantages of simple structure, lightweight and higher operability.
