description	The invention provides an assembly type prestressed arch plate foundation pit supporting system and a construction method thereof.The assembly type prestressed arch plate foundation pit supporting system comprises a plurality of parallel supporting stand columns, the supporting stand columns are vertically inserted into the boundary of a foundation pit, arch baffles are fixedly installed between the adjacent supporting stand columns, the camber direction of the arch baffles faces the outside of the foundation pit, and prestressed steel cables penetrate through the arch baffles; the prestress steel cables are used for providing prestress for the arched baffles. The supporting stand columns are inserted into the soil firstly, the supporting stand columns are smaller than reinforced concrete sheet piles in size, a static hydraulic pile driver can be adopted when the supporting stand columns are inserted into the soil downwards, construction noise is low, the supporting stand columns are inserted into the soil do
