Abstract: An integrated system comprising a barrier, such as a weir with movable gates, controllably blocks water flow in a natural or concrete lined channel. Without substantially impeding flow in normal conditions, the barrier is configured to back up flood waters to spill into an upstream prepared detention basin. Water is thus kept from downstream areas until subsequently drained through a controlled spill. Multiple units installed in a watershed can store significant amounts of flood water, e.g., during a hurricane, protecting life and property downstream. The electromechanically-operated gates can be operated locally or from a remote control center. Gauges and sensors positioned near the weir and/or throughout the watershed can provide data used to control one or more barriers in the watershed, and the data may be used to train a machine learning model to control the system.

Abstract: A static floodwall system that includes at least one floodwall section, and may include an access gate. The access gate may include a motor, control box, and drive system for moving a gate panel between open and closed positions. The static floodwall system may further include a plumbing system for transporting rain water from a dry side to a wet side. The floodwall system may be installed such that it is surface mounted, requiring minimal excavation. Methods of installing the floodwall system include creating a shallow excavation, adding compact fill and a top layer to the excavation site, and installing the floodwall section(s) on the top layer.

Abstract: The present invention relates to a retractable floodwall unit that comprises a foundation unit having a plurality of guide tracks along side walls of the foundation unit, a floodwall panel stowed in the foundation unit; a power system for raising and lowering the floodwall panel, and a plumbing system. The plumbing system is configured to remove ground water from a dry-side of the floodwall unit and flood water that becomes located in the floodwall unit.

Abstract: A trailer-mounted system and apparatus are provided to improve safety at road construction sites and other locations by allowing drivers to be signaled, and one or more lanes of traffic blocked, without having a flagger stand in or immediately adjacent to a road that is carrying traffic. The system and apparatus may have extensive data and audio and video networking capabilities to allow for remote control of the system and/or observation of the construction site. These networking capabilities may allow the system to further serve to enhance collaboration among remote worksites. A variant apparatus may be mounted on a highway divider such as a K-rail instead of a mobile trailer. Another variant provides a portable kiosk containing apparatus to supply the data networking and collaboration functions without the mechanical apparatus used to block traffic.

Abstract: A floodwall system comprises a plurality of wall panels detachably attached to a plurality of columns that are anchored to the ground. The plurality of wall panels include a plurality of chambers that receive water through perforations to increase the mass of these wall panels.

Abstract: A cover system for covering an entrance of an underground structure. The cover system comprises a frame structure attached to a foundation of the entrance; and a seal gasket configured to provide a seal between the frame structure and the foundation and between the frame structure and a panel of the cover system. The panel further includes a plurality of engagement members that engage the panel with the frame structure.

Abstract: A cover system for covering an opening, e.g., to an underground facility, watertight, includes one or more waterproof panels and a seal gasket for each panel, or a seal gasket common to a plurality of panels, configured to extend peripherally relative to the panel(s) and the opening, and adapted to be positioned between the panel(s) and the periphery of the opening, and one or more clamping devices for each panel which engage the respective panel and the periphery of the opening and/or structure extending over and attached to the opening to clamp the respective panel over the opening and compress the respective seal gasket.

Abstract: Disclosed anti-ram systems comprise at least one bollard section comprising a base of limited height and a plurality of spaced bollards extending upwardly from the base, which may be erected or installed on a paved surface such as asphalt, concrete, paver stones, etc., or on an unpaved surface such as soil, and need not be partially of fully buried, and yet can qualify for Department of State crash ratings previously assigned to buried bollard systems. Disclosed anti-ram systems also comprise a plurality of bollard sections and one or more connectors for interconnecting two or more of the bollard sections, and may also include an anchor or anchor system engaging at least each end of a bollard section not connected to another bollard section. The bollard sections may be filled with ballast and high friction structure may be attached to the bottom of the bollard sections to resist sliding after impact.

Abstract: An anti-ram system and method of construction having a shallow mounted base pad from which extend a plurality of bollards. Very little or only a shallow excavation is required for the base of the bollard system, which can be partially or fully assembled prior to bringing it to the installation site. The shallow mounting pad or base of the bollard system of this invention may be formed or constructed in various ways and of various materials, and in various configurations. The shallow mounting pad or base is constructed so as to have considerable mass.
