A concrete block construction method, including: manufacturing a plurality of concrete blocks each having a vertical guide hole formed in a vertical direction; preparing a guide member for installing the concrete blocks; forming a lower concrete block structure by installing at least one of the concrete blocks; placing the concrete block subject to be installed on the lower concrete block structure by inserting the installation guide pole into the vertical guide hole of the concrete block subject to be installed; and separating and recovering the guide member for installing the concrete block from the concrete block subject to be installed, after placing the concrete block subject to be installed.

A seawall constructed to provide an improved installation method and further provide a more resistant structure wherein the elements of the present invention are combined with an ultra high performance concrete to create the seawall of the present invention. The seawall includes a plurality of wall panel members wherein the wall panel members have a plurality of cells formed therein wherein the cells are hollow and extend between the upper edge and lower edge of the wall panel member. Wall panel connection members are configured to mateably couple adjacent wall panel members. The present invention further includes piling members configured to be journaled into the cells of the wall panel members and penetrate the ground underneath the wall panel member. A sub-cap member is superposed the wall panel member and is integrally formed therewith subsequent pouring of concrete. A top cap member is operably coupled to the sub-cap member.

A seawall may have an articulated sea-facing surface that forms pockets, tunnels, and other irregular surfaces that provide habitat for aquatic life. The seawall may be formed from panels of cast concrete, with the panels having protrusions extending from the sea-facing side. Extensions may be affixed to cast panels to further enhance the habitat created by the seawall and to attenuate incident waves.

A wall system includes a counterfort retaining wall forming at least one tier of the wall system, the counterfort retaining wall including counterfort beams and wall panels. The wall system further includes a mechanically stabilized earth (MSE) wall, the MSE wall positioned above the counterfort retaining wall. A bottom layer of the MSE wall is positioned above the counterfort beams of the counterfort retaining wall. The wall system further includes a plurality of fascia panels spaced horizontally from a face of the MSE wall and the wall panels of the counterfort retaining wall.

The invention relates to a retaining work (12) in ground (S), the work having a vertical front portion and separating a first portion of ground (S1) from a second portion of ground.

The front portion (14) is in the form of juxtaposed arched walls (16), each arched wall (16) presenting a concave side facing the first portion of ground and a convex side facing the second portion of ground, and the retaining work (12) further includes a rear portion (20) comprising a plurality of wall elements (22) having their largest faces extending vertically in the second portion of ground (S2), each wall element (22) being arranged between two adjacent arched walls (16) and extending transversely relative to the front portion (14).

The present disclosure relates to methods of stabilizing a seawall and reducing erosion around a seawall. Disclosed herein are methods of reducing erosion around a seawall, comprising injecting an amount of a sealing material to an injection depth at each of a plurality of spaced locations along a landward side of a new seawall. Also disclosed herein are methods for forming a chemical footer for a seawall comprising injecting a polymeric material to an injection depth from 1 foot to 3 feet below the mudline at each of a plurality of spaced locations along a landward side of a seawall. Additionally described herein are methods for reinforcing a seawall, comprising injecting a polymeric material to an injection depth at a plurality of spaced locations along the landward side of the seawall, wherein the injection depth is substantially at the vertical midpoint between the mudline and the top of the seawall.

This invention relates to nearshore solutions comprising: a plurality of bottom sitting infrastructure modules defining a boundary of the nearshore solution, and forming a lagoon: each of the plurality of bottom sitting infrastructure modules is adapted to transfer loads of the bottom sitting infrastructure modules to a seabed and withstand surrounding water pressure. The nearshore solutions further comprise general purpose modules which can be either bottom sitting or floating as well as the floating infrastructure modules are arranged within the boundary or seawall. Floating infrastructure module is designed to allow lighter infrastructure services, and for transport network such as vehicles to travel through or park connectors. General purpose modules are designed for live, work, play; to accommodate residential, office and recreational facilities, etc. The bottom sitting general purpose modules are designed to cater for heavier topside structures and the floating general purpose modules to cater for higher topside structures.

A quay wall absorption block includes a back wall, a cap, and a half columnar wall extending between the back wall and cap. The half columnar wall defines a plurality of chamber surfaces and mating surfaces on opposite sides thereof such that the chamber surfaces define portions of a plurality of closed-end flow chambers on opposite sides of the half columnar wall when the mating surfaces are in contact with corresponding mating surfaces of other quay wall absorption blocks. The half columnar wall also defines a plurality of flow paths that extends therethrough to fluidly connect the plurality of closed-end flow chambers on opposite sides of the half columnar wall.

Disclosed is a removable erosion-control and fencing (REAF) system for shoreline preservation along a line defined by a plurality of posts. An exemplary REAF system comprises first and second post clamp pairs mounted to adjacent posts. Each post clamp pair sandwiches a post and is fixedly attached to the post by virtue of fasteners that lock one half of the post clamp pair to its other half. In this way, the post clamp pair hugs the post and is secured thereon without having to be permanently fixed to the post or damaging the structural rigidity of the post. Each post clamp pair includes a substantially vertical wall slot such that one or more cross-members may be received into the walls slots to form a wall section in a space defined between the adjacent posts.
