摘要

Apparatus for slip-forming concrete to form a path comprising in combination a box having a front wall extending downwardly through the box, and a rear wall extending downwardly at an angle through the box to a location above the front wall, and opposing side walls coupling the front and rear walls extending downwardly to define the closed box having an upper opened end for receiving concrete and a lower opened end with a vertically disposed opened mouth defined by the vertical edges of the side walls and the lower edge of the rear wall, with the lower opened end having a smaller cross-sectional area than the upper opened end, and a screed for slip-forming the concrete, means for removably securing the screed at its edges to the side walls below the rear wall with the forward end of the screed being positioned at the opened mouth of the rear wall.
