A method for constructing a seawall section includes coupling an end of a substantially-waterproof barrier member to a footing. A concrete form is mounted to the footing such that a top end of the form is higher than an exposed upper surface of the footing. The concrete form defines at least part of a fill volume. Another end of the barrier member is coupled to the concrete form such that the barrier member extends over a side of the concrete form opposite the fill volume. Concrete is then poured into the fill volume and cured to form the seawall section. Prior to the curing, a body of water at the footing may be higher than the upper surface of the footing. However, the barrier member prevents water from entering the fill volume through the concrete form.

In one aspect, a tieback assembly is provided herein for supporting a SOE, the tieback assembly including: at least one anchor; an anchor threaded element extending from an end of the anchor; a tendon for transmitting force between the anchor and the SOE, the tendon including at least one tendon threaded element; and, a coupler having a body with a threaded bore, the tendon threaded element and the anchor threaded element threadedly engaging the threaded bore. Furthermore, the tendon is provided with sufficient length to extend at least from the coupler to externally of the SOE so that a portion of the tendon may be engaged externally of the SOE to allow for disengagement of the tendon threaded element from the coupler. Advantageously, the subject invention allows for at least partial removal of the tendon from a tieback assembly, including removal of the tendon threaded element.

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 structural tensioning system for selective coupling to a pier pipe having an elongate threaded rod and a tensioning device. The tensioning device having an elongate body that is configured receive a treaded end of the threaded rod and defines a slot in a distal end portion, a pair of opposed co-axial elongate openings, and a pair of opposed passages that communicate between respective portions of the slot and respective portions of the pair of opposed co-axial elongate openings. A portion of each elongate opening is configured to receive a bolt that is mounted in the pier pipe when the tensioning device is positioned in a tensioning position and portions of the slot, the pair of opposed co-axial elongate openings and the pair of opposed passages are configured to selectively receive the bolt that is mounted in the pier pipe as the tensioning device is moved to the tensioning position.

A foundation system for the implementation of thermosolar and photovoltaic plants that comprises a component (1) made from reinforced or prestressed prefabricated concrete constituted by a lower slab (2), a longitudinal central rib (3) in the top part and comprising a pillar (4) that emerges from the top part of the central rib. A method for implementing said foundation that comprises the phases: prefabrication (13) of a panel (1) of reinforced or prestressed concrete, the laying-out (14) of a bed of sand (12) over a surface, placing (15) the component (1) on said bed of sand (12), filling (16) with granular material (11) over the lower slab (2) of the panel (1) up to the upper reference mark on the pillar (4), placing (17) a supporting structure (9) inside the pillar (4), wedging (18) of the supporting structure, and filling (19) of the existing hollow using mortar.

A building element for coupling with other building elements to erect a retaining wall. Optionally, the building element can have a modular construction. The building element can have a face panel and a beam member that extends substantially perpendicularly relative to the face panel. The building elements can have a variety of different configurations, providing flexibility in the design of retaining walls. Optionally, each building element can define alignment voids that receive portions of alignment posts for ensuring vertical alignment between adjacent building elements or portions of building elements.

A caisson or casing 107 for installing a sheet 102/103 into a ground or underwater location, the caisson 107 having a shaped wall 107.1, which is open for a predetermined length and is adapted to receive and connect to an excavation means 3 within the confines of the caisson or casing 107. In at least one embodiment, the system includes a drilling assembly 3 for insertion of a caisson or casing 1, the drilling assembly 3 having one or more expanding drill bits 4 which are adapted to be driven by a drilling or rotation motive device 5, the expanding drill bits 4 being adapted to be arranged with respect to the caisson or casing 1 in use, so as form a hole or bore which substantially conforms to, or substantially overlaps with, the shape of the caisson or casing 1.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

A grout plug assembly for use in forming a pipe pile system defining at least one pile assembly inner surface portion comprises a resiliently deformable plug body and a substantially rigid plug cap. The resiliently deformable plug body defining a plug outer surface, a plug inner surface, a first plug end surface, a second plug end surface, where the plug inner surface defines a plug passageway. The substantially rigid plug cap defines a cap outer surface, a cap inner surface, a first cap end surface, and a second cap end surface. The second cap end surface is rigidly secured to the first plug end surface. The plug outer surface is sized and dimensioned to engage the at least one pile assembly inner surface portion of the pipe pile system during formation of the pipe pile system.
