A barrier member including: a support; a first engagement member coupled to the support; and a translatable column defining a longitudinal axis, wherein the translatable column is rotatably and translatably mounted relative to the support, wherein the translatable column is translatable between: a first position in which the translatable column and the first engagement member are spaced apart from one another such that the translatable column is rotatable about said longitudinal axis; and a second position in which the translatable column and the first engagement member are engaged to prevent rotation of the translatable column about said longitudinal axis.

A protective barrier includes a first end piece including a first opening and a first anchoring member for securing the first end piece to a surface, a second end piece including a second opening and a second anchoring member for securing the second end piece to the surface, a rail extending between the first end piece and the second end piece, the rail having a first end disposed in the first opening of the first end piece and a second end disposed in the second opening of the second end piece, and a cable system including a first fastener coupled to the first anchoring member, a second fastener coupled to the second anchoring member, and a cable having a first end attached to the first fastener and a second attached to the second fastener, the cable extending from the first fastener, through the first opening, through the rail, through the second opening, and to the second fastener.

A structural barrier and energy absorbing device comprises a plurality of structural elements. The structural element alone or in a plurality may serve as a traversal impediment or energy absorbing device, such as a pedestrian barrier, vehicular barrier, anti-tank obstacle, ballistic barrier, or the like. The structural element may be a tetrapod such that it comprises an element body having four extension portions that extend outwardly from the interior center to a distal end, such that the structural element maintains an identical orientation and a low center of gravity in each of four resting positions. The structural element may be a solid-state structural element comprised of a particular material or a portable and collapsible structural element wherein the element body comprises an outer skin defining an interior void space, such that during set-up or installation the interior void space may be filled with a filler substance onsite.

An intelligent vehicle capturing apparatus for a high-pier bridge includes: a double-layer metal protective net, support unit and actuation unit connected thereto. The protective net mounts to a high-pier bridge backside through the support unit. The actuation unit includes a hydraulic link mechanism connected to one end of the protective net. The hydraulic link mechanism unwinds the protective net to capture a vehicle. The apparatus stops a vehicle rushing off a high-pier bridge. Upon completion, a hydraulic system drives a third hydraulic cylinder in a support rod on the high-pier bridge backside driving a rolling shaft rotating, winding and placing a protective net on the high-pier bridge backside. The apparatus has a simple structure, is practical and easily used, useful on hazardous high-pier bridges protecting vehicle passengers and avoiding traffic accidents resulting from vehicles rushing out of the high-pier bridges.

Disclosed herein is a bollard system including an impact receiving post and a foundation cage. The impact receiving post includes an outer surface, a proximal end, and a distal end. The foundation cage defines a three-dimensional lattice structure. The foundation cage is coupled to the proximal end of the impact receiving post and is configured for installation in concrete beneath a ground surface. The foundation cage defines a recess to receive a proximal portion of the impact receiving post. The foundation cage includes a horizontal stop member at least partially extending across the recess and supporting the impact receiving post and preventing the impact receiving post from extending further into the foundation cage before the concrete sets.

A security barrier includes a plurality of barrier islands. Each barrier island has a concrete crash block having at least one pair of opposing side faces and external fixing elements on the opposing side faces. Attachments, which may be flexible attachments, extend between the external fixing elements of adjacent barrier islands of the security barrier. Each barrier island also has one or more load transfer element within the concrete crash block and, under load, the load transfer elements transfer load from the external fixing elements on one side of the concrete crash block to the external fixing elements on the opposing side of the concrete crash block.

A moving energy absorbing component includes an impact head including a base and upright projection. The base includes an axial orifice extending from a downstream entry point to an upstream exit point, through which an upstream terminus of an FTE rail is passed before the FTE rail is directly or indirectly connected to a releasable connection point coupled to a ground anchor. The impact head is connected via at least one beam to a post detacher element located downstream of the impact head a pre-determined distance therefrom.

A crash attenuator system for deployment in front of a fixed structure includes a rail extending along a length of the crash attenuator system and a plurality of diaphragms initially disposed in spaced relation along the length of the rail. Each of the plurality of diaphragms moves along the rail, so that when a front end of the crash attenuator system receives an impact force from a vehicle, a first one of the diaphragms moves rearwardly along the rail and impacts a second one of the diaphragms so that both the first and second diaphragms move further rearwardly along the rail, this process continuing with additional ones of the diaphragms until the impact forces have been fully attenuated. A tearing member on the crash attenuator system engages material forming a tearable member of the crash attenuator system, the tearing member tearing material forming the tearable member to increase attenuation of the impact force.

A concrete-based composite material including iron rich particles is characterized by an iron content greater than 17% by weight of the composite material, can include iron particles which are an iron by-product recovered from iron slag material, can include iron rich particles which have an iron content of at least 60% by weight of the iron rich particles, and/or can include iron particles having a particle size distribution in the range of about −⅜ inch to +60 mesh or in the range of about −20 mesh to about +60 mesh. The composite material can include ground granulated blast furnace slag as a portion of the cementitious component of the composite material. A method of forming a structural element from the composite material includes casting the structural element such that the structural element is characterized by a ballistic performance of Level 10 as defined by Underwriters Laboratories standard UL752.

A crash cushion includes a number of spaced-apart supports or bulkheads; energy absorbing modules positioned between the supports; overlapping side panels that interconnect the supports and envelop the energy absorbing modules; front and rear fixed anchors; and reinforcing cables extending between the anchors. The cables extend through cable guides formed in the supports so as to stabilize the supports and facilitate controlled collapse of the supports during vehicle impacts.
