An axial reinforcement system is disclosed that provides a shell (i.e., a form or jacket) that protects a weight-bearing member (e.g., a cement column) from a corrosive environment and which also substantially increases the structural capacity of the weight-bearing member. The shell is integrated with “positioners” and reinforcing elements, the combination of which offers several advantages over conventional shells. The positioner is attached directly to the shell and the positioner is, in turn, secured to a reinforcing element, which can be a reinforced steel, such as rebar, or a carbon fiber reinforced polymer material. The axial reinforcement system has been found to substantially increase the structural rigidity of the weight-bearing member, while at the same time protecting the weight-bearing member from corrosion and is also simple to install.

A method of rehabbing reinforced concrete pilings while in service and without the requirement to demo or otherwise gain access over the ends of an existing column. Design adopts modern environmentally responsible fiber reinforced polymer rebar and other FRP stirrups uniquely shaped into spiral sections requiring only side access for placement, designed to permanently encase the piling with a totally non-rusting non-metal reinforcement lateral containment cage featuring preformed circumference stirrups that mechanically interlock vertically and lateral adjustability to control density. The spiral stirrups extending fully 360-degrees around an existing piling with an additional overlap of at least 45 degrees.

The invention relates to a foundation pile comprising a stabilization device that is located within the foundation pile and is connected to at least two inner surface sections of the foundation pile; the stabilization device allows compressive and/or tensile forces to be transmitted such that the stabilization device counteracts lateral deformation and/or torsional deformation of the foundation pile.

The present disclosure relates to a prop (10) comprising a first tube (14) and a second tube (16). The first tube (14) is telescopically connected to the second tube (16) for axially displacing the second tube (16) between a retracted position and an extended position. The first and second tubes (14, 16) each comprise a loading end for receiving an axial load from opposing load surfaces (62, 64) in the extended position. The first tube (14) and the second tube (16) are made from a plastics material.

A sheet pile of concrete comprising a reinforcement (1) which is produced from composite material comprising fibres and a concrete casting (2) which extends between a first lateral end (3) thereof and an opposite second lateral end (4) thereof, the reinforcement (1) being embedded in the concrete casting (2). The sheet pile further comprises a terminal element (6) which is produced from a polymer material and which comprises a connection element (7) which is embedded in the concrete casting (2) and an engagement element (8) of the sheet pile (100) which is connected to the connection element (7). The connection element (7) and the engagement element (8) extend along a longitudinal axis (X) of the sheet pile, in which the engagement element (8) has a practically C-shaped cross-section and projects from the first lateral end (3) of the concrete casting (2). The second lateral end (4) of the concrete casting (2) comprises a concrete joint (9) which extends longitudinally along the longitudinal axis (X) and which is shaped so as to be connected in an interlocking manner to the engagement element (8) of a second sheet pile.
