The invention relates to a self-compacting concrete aluminum alloy edge-sealing formwork for a ballastless track. The self-compacting concrete aluminum alloy edge-sealing formwork for the ballastless track comprises two end molds, four standard side molds, two adjusting side blocks, four corner formworks, and four inserting boards, which are symmetrically assembled into the quadrilateral self-compacting edge-sealing formwork, wherein the end mold comprises a panel and upper and lower frame plates, a reinforcing rib is arranged in the middle part of the panel to form a groove shape, and the end mold is integrally molded by extrusion once through an aluminum profile extrusion device; the standard side molds and the adjusting side molds are made of square tube aluminum profiles, and are molded by extrusion once through the extrusion equipment, the corner formworks and the inserting boards are made of arc-shaped aluminum profiles, and are molded by extrusion once through extrusion equipment. The self-compacting concrete aluminum alloy edge-sealing formwork for the ballastless track provided by the invention solves the problems of slow turnover of the formwork, fewer use times, easy deformation, easy rusting, formwork swelling and mortar leakage of self-compacting concrete, poor exhaust effect, uneasy installation, great waste of human resources and the like under construction.
