The present invention relates to soft ground improvement work, especially a track with an excellent load dispersion effect is formed, and a bogie, having a paving means by conveyor, moves back and forth on the track, and said bogie is provided with rotatable bidirectional conveyors, so that the location of sand or debris, which is soil covering material, is adjusted to perform economical and speedy paving According to the soft ground soil covering method and the soil covering apparatus of the present invention using a track of load-dispersing structure and a bidirectional conveyor bogie, it is possible to move the bogie and paving means, which are heavy objects, stably on the surface layer of soft ground having high water content and deformability, and it is possible to load a large quantity of soil covering material by the dispersion effect of concentrated load, so work continuity is excellent In addition, in the present invention the construction is performed to both sides from the central portion of soft ground separated by the track, so settlement and elevation of ground are minimized; and the maximum paving area is secured within a single section of moving back and forth, so the work period can be remarkably shortened so as to be very economical

Method and apparatus for soil covering of soft ground

A banking material paving equipment using the conveyor is provided to have the hopper structure and to transport the banking material to conveyor safely. A banking material paving equipment(10) using the conveyor comprises a car body(2) which is installed on the caterpillar, a leader(3) installed so that the angle adjustment is possible, a conveyor(4) installed along the leader, a hopper(5) which is installed on the car body, and which consists of a top container(5a) and a bottom container(5b) supplying the banking material to conveyor, an auxiliary conveyor(6) in which one end is connected to the top container and a bucket(7) is installed at the other end.
