Formwork (1) for the construction of railway platforms, comprising: a container (2) in which building material to be shaped and subjected to hardening for the construction of a railway platform can be compacted; at least one fixed crossbeam (3) located at the bottom of the container (2); at least one movable crossbeam (4) provided with at least one pair of fastening imprints (5) arranged symmetrically and configured to model the material to form a pair of fastening seats apt to position the rails on the railway platform; placed side by side with the fixed crossbeam (3) and defining therewith an impression surface on which said material can be molded for the construction of said railway platform; said movable crossbeam (4) being rotatable and/or translatable with respect to said fixed crossbeam (3), the configuration being such that different rotations and/or translations correspond to different positions in the container (2) of the fastening imprints (5) and different impression surfaces.

Various embodiments of an adjustable mold and method for making precast concrete traffic barrier panels with different geometries are disclosed. The panels are used for creating a continuous traffic barrier by placing the panels in a contiguous side-by-side arrangement adjacent a roadway atop a modular earth retaining wall. Each traffic barrier panel has a body with at least front, back, top, bottom, left, and right sides. The mold body has a plurality of walls that define an interior chamber, a door opening to the interior chamber, and a concrete inlet to the interior chamber. The door is designed to be installed on and to be uninstalled from the mold body to respectively close and open the door opening. The door has left side and right side forming panels that are designed to define respectively a left side two-dimensional geometry and a right side two-dimensional geometry of the left and right sides respectively of a traffic barrier panel to be made. The left side and right side two-dimensional geometries are changeable by interchanging the door with differently oriented forming panels or by adjusting two-dimensional orientations of each of the left side and right side forming panels on the existing door. The interior chamber of the mold body in combination with an interior side of the door define an outer surface geometry of the front, back, top, bottom, left, and right sides of the traffic barrier panel to be made.

A molded concrete U-wall construction block including a molded concrete U-wall construction block structure formed from cured concrete poured about a block cage made from reinforcing material during a block manufacturing process. The block cage includes an open aperture formed in each of its stem reinforcing portions. During the block manufacturing process, the first and second support members of a support mechanism are inserted within the open apertures formed in the stem reinforcing sections of the block cage, and cooperate with the open apertures of the block cage so as to (i) support the block cage when being loaded into a block manufacturing machine, (ii) define central apertures molded in each stem portion of the concrete U-wall construction block structure, and (iii) lift the molded concrete U-wall construction block when being unloaded from the machine.

Void former assembly for casting facing elements for reinforced earth. Anchoring recesses are cast into its rear face so that earth-reinforcing strips can be looped through. The anchoring recesses are each formed as a loop channel having a convex inner surface and a concave outer surface, at least one of which has a radius of curvature which increases from the deepest part of the recess towards the rear face. A removable void former assembly and method for casting such facing elements are also described. Because of the varying radius of curvature of the surfaces of the channel, and the rotational and translational withdrawal path of the void formers, the channel can be cast deeper, and with openings which are closer together, than has hitherto been possible using removable void formers.

A machine for and method of manufacturing concrete U-wall type construction blocks by molding each concrete u-wall construction block from concrete poured about a block cage made from reinforcing material while said block cage is loaded within the machine. The method involves providing a system of molding jacket panels, including a core molding assembly having a pair of inside stem jacket panels that are adjustably supportable in a substantially parallel manner during a molding process, and arranged is such a manner that the front wall portion is molded in downwardly facing direction toward a horizontal support surface and completely enclosed in one or more molding jacket panels. Before block molding operations, the thickness of the front wall portion of the U-wall construction block is set by determining the thickness of a front wall surface liner and installing the front wall surface forming liner within the system of molding jacket panels.
