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.

The invention relates to a cover for use on public roads, comprising an outer body (2) that houses at least one reinforcement (1). Preferably, said outer body (1) is made of a plastic material, e.g. injected plastic material, and said at least one reinforcement (1) is connected by means of said outer body (2) to form a single piece.

The cover according to the invention is lighter than that conventional covers, given that it is made with less metal and with lighter materials. Moreover, the cover cannot be easily recycled and hence is not at risk of theft.

An electrically conductive geosynthetic clay liner incorporating an electrically conductive textile graphene.

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.

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 continuity connection system is disclosed that is highly durable, simple to install, and substantially increases the structural capabilities and weight-bearing capacity of a shell (i.e., a form or jacket). The shell can be used to protect a weight-bearing member (e.g., a cement column) from a degrading environment. The shell can have one or several layers of carbon fiber fabric (e.g., spaced apart longitudinally) wrapped around an interior of the shell or embedded within the shell. The continuity connection system is used to provide continuity between two ends of the carbon fiber layer, and can be made up of the carbon fiber fabric reinforcement layer, two pockets, and a laminate having ends positioned in each pocket. The carbon fiber laminate traverses a seam/separation of the carbon fiber fabric and/or a seam of the shell and can be retained in place within the pockets with an appropriate epoxy, for example.

Geocell structures stabilize water body shorelines and beds, slopes and retaining wall bridge abutments in such areas of construction as the oil and gas, transport and hydraulic engineering industries, amongst others. A blank for producing a weld-free geocell is made from a polymer sheet material having incisions therein in the form of segments of parallel lines. Adjacent incisions in the same row have a distance S between the ends thereof and the relationship S/L=K1, where K1 is from 0.1 to 0.5. The incisions of adjacent rows are at a distance D from each other and have the relationship D/L=K2, where K2 is from 0.1 to 0.7. At the ends of the incisions, there are openings which are oval or circular in shape. A weld-free geocell includes at least one blank stretched in a direction perpendicular to the lines of the incisions to form a three-dimensional cellular structure.

Wall reinforcement systems and methods of reinforcing wall structures are provided. The systems and method include at least one carbon fiber strap (CFS) adhered to a wall structure, in which the CFS and an anchoring pin are configured to form a composite anchor that is secured within a hole located at or proximate a bottom end of the wall and extends into a foundation portion.
