Abstract:
A mortarless wall structure (10) comprising a plurality of preformed, stackable blocks (12, 112, 160, 312) with the blocks operatively connected to each other by a plurality of elongated, vertically oriented, support beams (16, 116, 270, 287). The blocks may include one or more channels (140, 142a, 142b, and 144) that are configured and arranged to intercept moisture traversing from the front surface (120) toward the rear face (122) of the block, and to direct the moisture in a predetermined direction that does not intersect the rear face. The wall (10) may be freestanding or operatively connected to a suitable support structure by one or more brackets (18, 19, 200, 230). When used in conjunction with a support structure, the wall may be provided with a sealing element (250) that prevents moisture and debris from being introduced between the wall and the support structure.
Abstract:
Retaining wall systems and methods of making retaining wall systems are disclosed. In one embodiment, the retaining wall system includes a first horizontally-extending course of sand/soil bags and a second horizontally-extending course of sand/soil bags positioned vertically adjacent to the first course of sand/soil bags, with an interconnecting member that attaches the first course of sand/soil bags to the second course of sand/soil bags. The interconnecting member has an upper side and a lower side, wherein at least one of the upper side and the lower side has a first projection that includes a notch therein to engage geogrid.

Abstract:
A retaining wall block system having multiple sizes and shapes of blocks with differently dimensioned, interchangeable front and back faces. The blocks are used to construct an irregularly textured wall having a weathered, natural appearance. Multiple channels in the lower face of the block are used to engage pins in pin -receiving apertures to form an attachment system. Horizontal reinforcing members are also used in the channels and vertical reinforcing members are used in cores of adjacent blocks for reinforcing a wall. Reinforcing geosynthetic materials can also be firmly held in a wall by means of the pins or by connectors adapted to fit in the block channels.
Abstract:
A modular block wall includes dry cast, unreinforced modular wall blocks (40) with anchor type, or frictional type or composite type soil stabilizing elements (42) recessed therein and attached thereto by vertical rods (46) which also connect the blocks (40) together. The soil stabilizing elements (42) are positioned in counterbores or slots in the blocks (40) and project into the compacted soil (48) behind the courses of modular wall blocks (40). Alternative stabilizing element designs may be used with the modular wall blocks (40) and other types of facing elements in a mechanically stabilized earth structure.
Abstract:
The present invention relates to a security barrier (1) for deployment in crowd control and/or containment, the security barrier being capable of adopting at least two configurations. In a first configuration the security barrier is erected for deployment and comprises a compartment bounded at its front by a front panel (5, 6, 7) for providing a barricade, at its rear by a rear panel (12, 13, 14) of lower height than the front panel, at its sides by respective side panels (8, 9, 10, 11) pivotally connecting the rear and front panels, and at its bottom by a bottom panel (15, 16, 17) connected at least two of the front panel, the rear panel, and the respective side panels. In its second configuration the security barrier is collapsed for storage and/or transportation.
Abstract:
The present disclosure concerns methods for constructing a dry-stacked retaining wall that is reinforced to increase the sliding resistance of the wall. In particular embodiments, a concrete footing or base is formed in trench below the lowermost course of retaining wall blocks and extends upwardly into voids in the lowermost course of the wall. The voids can be, for example, chambers or openings defined between adjacent blocks or vertically extending cores formed in the blocks.
Abstract:
A block has a finished surface that provides an attractive appearance. The block is relatively large in size, allowing the quick construction of a wall, such as a retaining wall, using the block. The block includes one or more lift and alignement devices in the block that allow the block to be lifted using a suitable lifting apparatus, such as a crane, forklift, backhoe, etc. The block includes one or more recessed portions in the bottom surface of the block positioned to receive the protruding lift and alignement device of a previously-laid block underneath, thereby helping to align the block with the previously-laid block. The block includes one or more voids that extend from the top surface to the bottom surface of the block, and that align with each other when the blocks are stacked into a wall, thereby allowing fill material to be placed in the voids to strengthen the wall. The preferred embodiments also include a wall system with various different blocks that may be used to built a wall.
Abstract:
The present invention relates to a system and method for constructing a pre-stressed modular construction for supporting or retaining an applied load. In particular, the present invention relates to a system and method for pre-stressed modular retaining walls. The system comprises a plurality of header stacks (101) constructed from a variety of header units (110). The header stacks are coupled by structural members (130). Active reinforcement elements (115) are used to induce a pre-stressing force into the header stacks to support or retain the applied load. A method for constructing the modular construction is provided.
Abstract:
A retaining wall construction comprises modular facing blocks (32) connected by fasteners (36) to anchoring blocks (34) positioned behind the facing blocks (32). The facing blocks (32) are arranged in courses which overlap one another. The facing blocks (32), as well as the anchor blocks (34), have hollow, vertical throughbores (70). This enables interconnection of the back wall (68) of the facing block (32) with the anchor block (34) by means of various types of fasteners (36). The retaining wall construction is especially useful in the construction of low height, gravity type walls.
