Construction system and construction method of pile plate type soilless roadbed pile plate connecting structure

According to the construction system and the construction method of the pile plate type soilless roadbed pile plate connecting structure, the welding position of an inner supporting ring and an outer sleeve steel cylinder can be set according to the pile top elevation condition and the beam plate bottom elevation condition through an arranged supporting component, the flexibility is high, and personnel do not need to mount and dismount temporary supporting components at high altitude; the two opposite sides of the supporting component serve as shelving platforms of a beam plate and are connected with a construction platform to facilitate operation of workers, the other two sides are connected with a formwork system, the supporting component and the formwork system can be connected into a whole in advance before construction, then the supporting component and the formwork system are installed on the top of a pile, the trouble of assembling and disassembling a large temporary support is reduced, and constructio
