An interlock connector interlocks building blocks that are assembled so as to provide a wall structure. The building blocks have respective front surfaces for defining a front façade of the wall structure and respective rear surfaces with at least one respective horizontal groove. The interlock connector comprises first and second bodies. The first body is inserted in the rear surface horizontal groove of a first building block. The second body is inserted in the rear surface horizontal groove of a second building block adjacent the first building block. Insertion of the first and second bodies in the respective rear surface horizontal grooves of the first and second building blocks provides for interlocking the first and second building blocks.

What is provided is a precast hollow block, a precast wall system incorporating the precast hollow block, and forms for manufacturing a hollow block and a coping cap. Accordingly, the precast hollow block and its incorporation into a precast wall system provide solutions to current “level up” block coping techniques, wall flood protection, wall force protection, and the like. Instead of having mismatched or missing face textures on sloped portions of the wall, the precast wall system allows for easier installation of face-textured blocks directly at the top of the wall. As a result, the precast wall system may readily account for slope transitions of a wall, conform to specific Department of Transportation project requirements, accommodate existing wall construction specifications, and be easily customizable for a variety of applications.

A tieback alignment and access device has a hollow core and vertically aligned angled anchor subassemblies that provide attachment points for tieback anchors that pass laterally through the hollow core. The hollow core is configured to allow a cutting tool (e.g., a drill bit) to be inserted therein longitudinally and used to cut the tieback anchors at any time. When cast into a contiguous temporary support-of-excavation wall, the angled anchor subassemblies are set back from an outwardly facing surface of the wall resulting in a smooth surface.

An apparatus includes a monolithic retaining wall formed by combinable modular retaining wall blocks. Each of the combinable modular retaining wall blocks defines (A) vertical grooves extending along a vertical direction, and (B) horizontal grooves extending along a horizontal direction. This is done in such a way that the monolithic retaining wall, which is formed by the combinable modular retaining wall blocks, defines (A) spaced-apart instances of the vertical channels extending vertically through the monolithic retaining wall, and (B) spaced-apart instances of the horizontal channels extending horizontally through the monolithic retaining wall, in which at least some of the spaced-apart instances of the horizontal channels intersect at least some of the spaced-apart instances of the vertical channels.

This disclosure provides methods, systems, and kits for building seawalls using mechanically interlocking blocks. The interlocking blocks have interiors that can be filled with sand, gravel, or cementitious material after formation of a wall. The interlocking blocks that can be connected on any side to form a structure, wall, foundation, floor, building, flotation device, gardening structure, or toy. The interlocking blocks typically comprise center openings and connecting openings on each side and can be connected with hardware through the connecting openings. The center openings allow for materials such as pipes, wires, conduit, and rebar to pass through interlocked blocks. Connected blocks can also be filled with fortifying material to strengthen the structure. Sides of connected blocks can be covered with faceplates to direct flow of fortifying material and aid in the creation of desired configurations. Also provided are connectors for connecting sides of the interlocking blocks.

A multi-part reusable retaining wall and levee bag. The reusable levee bag includes a top bag section and a bottom bag portion removably affixed to the top bag portion. The combined top bag section and bottom bag portion define an interior space within which fillable material may be received to form a levee bag for use in flooding and other installations. The bottom bag section includes a receiving cell for receiving an end of another levee bag to connect multiple levee bags end to end to form a retaining wall with minimal gaps between levee bags. The bottom bag section is made of a biodegradable material while the top bag section is made of an alternative material. The reusable levee bag, once filled, may be disassembled and the top bag section reused while the bottom bag section may remain in place to biodegrade.

A simulated stone or brick column or retaining wall is made up of rows of masonry blocks of generally trapezoidal configuration arranged in end-to-end relation to one another in each row, each block including a recessed portion being aligned with one another in each row and each block having textured wall surfaces simulating the appearance of brick or stone along one or more wall surfaces arranged in different configurations without the necessity of interlocking the blocks together.

A triangle unit assembly block comprises a body portion comprising mutually facing first and second side surfaces and mutually facing third and fourth side surfaces between a upper surface and a lower surface; a first fastening protrusion formed on the first side surface of the body portion; a second fastening protrusion formed on the second side surface of the body portion; a first fastening groove formed on the third side surface of the body portion; and a second fastening groove formed on the fourth side surface of the body portion, wherein the first and second fastening protrusions are disposed to correspond to each other and protrude in mutually opposite directions, and the first and second fastening grooves are disposed to be misaligned with one another to be concave in mutually facing directions.
