A building element for coupling with other building elements to erect a retaining wall. Exemplary building elements have receiving spaces for receiving increased weight of fill material to provide increased stability. Optionally, each building element can have an enlarged face profile that provides efficiency in the shipping and assembly process. 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 void former to form a void in an earth retaining cast block during casting, the void configured to locate a strap for a strap stabilised earth structure.

A retaining wall anchoring system for securing a retaining wall by coupling it to an anchor member via a plurality of coupled pieces of rebar includes a wall structure formed of a plurality of blocks, each block having a passage that aligns with each passage of the other blocks to define a channel. A rigid anchor member is encased in a quantity of a soil. A plurality of pieces of rebar couple the anchor member to the wall structure. A wall piece of the plurality of pieces of rebar extends through the channel, and a wall fill fills the channel, encasing the wall piece and securing it to the wall structure.

Moulding insert (8) for a mould manufacturing a concrete facing block (4) for a reinforced-ground structure (90), said reinforced-ground structure comprising a facing formed by such facing blocks and a fill in which reinforcements connected to the facing are installed, the moulding insert (8) comprising a shell (1), delimiting a general space of a connection connecting a reinforcement (3) to the facing block, a core envelope (2) obtained by moulding the shell separately, the shell having a first lateral face (15) pierced with a first orifice (11), in which a first end portion (21) of the core envelope is fitted, characterised in that the core envelope is in the general form of a truncated cone.

A precast H block (3) interlock each other to form sloping wall and similarly precast Y block (10) interlock each other to form straight wall, both block having a pin hole (4) through side walls. A wire rope (5) passing through said pin hole to make a wall strengthened by nailing horizontally (14) into the earth (8) adjacent to the block and vertically nailing (9) at top and bottom level. As well as wire rope (5) passing through said pin hole (4) of uppermost blocks, from underneath the road, to make a wall/barrier strengthened by nailing vertically (9) into the earth across the road (2).

A winch anchoring assembly includes rack has an anchor portion and an attachment portion. The attachment portion has a first engagement that is attachable to a winch line of a vehicle. A plurality of spikes is coupled to and extends downwardly from a respective one of the anchor portion and the attachment portion of the rack. Each of the spikes is oriented to angle forwardly toward the first engagement on the attachment portion. In this way the spikes sink into the ground when the winch line pulls on the first engagement thereby facilitating the rack to resist being pulled out of the ground when the winch line is pulling the vehicle. A second engagement is coupled to the anchor portion of the rack and an anchoring line can attached to the second engagement thereby inhibiting movement of the rack when the which line pulls on the rack.

An anchoring member (15) capable of being integrated into a facing element (10) for the creation of stabilized earth structures, comprising a shell (21) that defines a recess (18) with a mouth (13). An anchoring bar (20) extends transversely within the recess (18) in such a way that, in use, an elongated stabilizing member for stabilized earth structures, such as a strip or similar, can be made to pass around it by inserting it into the mouth (13).

A peg for securing matting to the ground includes a shaft extending between a first end and a second end along a longitudinal axis, and a head portion extending radially outwardly from the first end of the shaft. The head portion has a contact surface, from which the shaft extends, for contacting the matting and holding the matting against the ground. The shaft has first and second threaded portions and first and second non-threaded portions. Each threaded portion has a screw-thread and is spaced apart from an adjacent threaded portion by a non-threaded portion. The first non-threaded portion extends from the second end and the second non-threaded portion extends between the first and second threaded portions.

A sheet pile retaining wall system employing corrugated sheet piles not requiring temporary shoring to be used when widening and/or stabilization of existing highway embankment. The wall system provides a front face wall having a plurality of resistance fins perpendicularly extending therefrom via three-way connectors. The fin sheet piles first include a brace fin sheet for reducing stresses in the front face wall, then a series of additional resistance fin sheets terminating at an elevation below the face wall for accommodating a pipe drainage/utility cradle. Between the slope of the existing embankment, a temporary excavation bench, an excavation backslope, and the higher front face wall is reinforced concrete backfill for pre-stressing the wall system when fluidand, when set, optionally engaging supplementary structural features within the set concrete backfill such as dowels/tie down anchors.

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.
