A method of disassembling a support column structure can include de-coupling a plurality of first reinforcing bars from a removable portion, lifting the column portion off the removable portion, and de-coupling a plurality of second reinforcing bars from the removable portion. The first reinforcing bars can coupled to and extend from a column portion and can be spaced from a base portion. The second reinforcing bars can be coupled to and extend from the base portion and can be spaced from the first reinforcing bars and the column portion.

The invention provides components, structures, methods, and assemblies for controlling sedimentation and debris flow associated with soil erosion. The invention also provides components, structures, methods, and assemblies that are useful for anchoring fiber rolls along a sloped surface.

It is foreseen that the footing be executed in an excavation, such that a lower concrete slab (2), with its corresponding steel reinforcement, is obtained at the base of the same, and upon which a plurality of prefabricated partitions (3), likewise of concrete, are radially disposed in the shape of a crown at a prefabricated or executed in situ concrete zone (4), such that the spaces defined between these elements are filled with the material (5) obtained by means of the excavation, in order finally to achieve a total or partial upper slab (1) upon this assembly. In this way, and by means of the inclusion of prefabricated elements, the construction works are simplified, which affects favourably both the time frame of execution and the fabrication costs.

Disclosed herein are support column structures which can be used to support bridges, buildings or other structures. In some cases, a support column structure can be deconstructable and include one or more removable elements. In some cases, a support column structure can include shape memory alloy reinforcing bars. In some cases, a removable element of a support column structure can include an engineered cementitious composite. In some cases, a removable element includes one or more sleeves to separate an engineered cementitious composite from one or more shape memory alloy reinforcing bars. Methods include assembling and disassembling a support column structure.

An edge protection safety bund system (10) for use in connection with a rock bund made of rock fill. The edge protection safety bund system (10) comprises a bund module (12) having a barrier wall (14) and a base plate (16). The bund module (12) is preferably one of a plurality of bund modules (12) arranged side by side to form an extended barrier wall (14). The barrier wall (14) of each module (12) extends substantially perpendicularly upwards from the base plate (16), and a support web (18) extends at an angle from a rear face of the barrier wall (14) to an upper surface of the base plate (16). In use, when rock fill is dumped onto the rear of the bund modules (12), and allowed to flow back to its natural angle of repose behind the barrier walls (14), it creates a rock bund (20) with a front face formed by the extended barrier wall (14).

A fatigue resistant gravity based spread footing under heavy multi-axial cyclical loading of a wind tower. The foundation having a central vertical pedestal, a substantially horizontal continuous bottom support slab, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal, ribs and slab forming a continuous monolithic structure. The foundation having a three-dimensional network of post-tensioning elements that keep the structural elements under heavy multi-axial post compression with a specific eccentricity intended to reduce stress amplitudes and deflections and allows the foundation to have a desirable combination of high stiffness and superior fatigue resistance. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

A structural design of a foundation that is configured to reduce size, fabrication time, material usage and installation time by prefabricated machine produced structural cellular and/or volumetric design that distributes and redirects stress loads from the above over extended exterior surface contact areas of a below grade embedded foundation.
