摘要：The method is immediately active, and is for the road bed, carrying ballast and rails, esp. of street railways. It utilises the better layers, and uses modified track construction methods, together with at least one tamper press head. Prefabricated concrete posts (8) with reinforcements, are placed into every sleeper section (18) near the rails (16), in track sections to be renewed, dependant upon the condition of road bed and superstructure. The posts are placed through the bed (13), vertically or at an angle, into the ground. ADVANTAGE - Requires no work on ground or road bed.
