A noise abating wall including piers with integral column members, columns each including two laterally extending wing walls, and a spandrel panel. The piers are secured in spaced ground holes with column members extending vertically from the pier securing the columns in a vertical orientation with the wing wall outer sides having a selected spacing from one wing wall of an adjacent column. The spandrel panels are wider than the selected spacing of wing walls of adjacent columns whereby the spandrel panel sides overlap the sides of adjacent wing walls. First connectors on the spandrel panel front face adjacent both of the panel opposite sides and second connectors on the wing wall rear faces adjacent the wing wall outer sides connect together to secure the overlapping walls and spandrel panels in substantially face to face contact.

The present invention corresponds to a device for deflecting and decelerating a flow comprising a deflecting surface, a support structure connected behind the deflecting surface and a vortex generator connected on the deflecting surface, where the vortex generator generates two turbulent flow zones, a first low pressure zone below the vortex generator and a second high pressure zone above the vortex generator, and where the deflecting surface is concave in the direction of the incident flow, and the vortex generator is on the concave part.

The sound absorbing board includes a body and multiple sound absorbing elements. The body has a first side surface and a second side surface. The multiple sound absorbing elements are formed on the body at spaced intervals, and each one of the multiple sound absorbing elements has a protrusion, a groove, and two sound absorbing openings. The protrusion is formed on the first side surface of the body. The groove is formed on the second side surface of the body and has multiple concave portions and at least one convex portion. The multiple concave portions are formed on a bottom surface of the groove. The at least one convex portion is formed on the bottom surface of the groove, and is formed between two adjacent ones of the multiple concave portions. The two sound absorbing openings are formed on the two opposite side surfaces of the protrusion, respectively.

A pre-cast concrete column with cast in place footing and a sound barrier made using the same.

Systems and methods are disclosed for a highway sound wall system comprising a sound wall panel assembly filled with loose foam glass aggregates. The highway sound wall may further comprise a pair of spaced apart vertical members. The vertical members may be H-beams having a flange portion and a body portion. The highway sound wall may further comprise a pair of spaced apart mesh members extending between and retained within the vertical members, thereby forming the sound wall panel assembly. Each of the vertical members may have at least one stop block attached to the flange portion and at least one stop block attached to the body portion. At least one vertical edge of the mesh members may have an attached bar which engages both stop blocks. The sound wall may be temporary or permanent.

Airborne acoustic absorbers include periodic arrays of Helmholtz resonators that are covered and/or partially filled with an acoustically absorptive material, such as a thermoplastic foam. The combined structures have much broader frequency ranges of high acoustic absorption than do structures having only Helmholtz resonators or acoustically absorbing foam.

A barrier wall has a first vertical support and a second vertical support. A first wall panel is disposed between the first vertical support and second vertical support. A second wall panel is disposed between the first vertical support and second vertical support over the first wall panel. An I-beam is disposed between the first wall panel and second wall panel. The I-beam includes a first flange and second flange extending into the first wall panel and second wall panel. A cable is disposed between the first wall panel and second wall panel. The I-beam includes a ridge around the cable. A grounding cable is attached to the I-beam. The first wall panel includes a first channel extending for a length of the first wall panel. A first sound absorbing material strip is disposed in the first channel. A traffic barrier is disposed under the first wall panel.

A barrier wall has a first vertical support and a second vertical support. A first wall panel is disposed between the first vertical support and second vertical support. A second wall panel is disposed between the first vertical support and second vertical support over the first wall panel. An I-beam is disposed between the first wall panel and second wall panel. The I-beam includes a first flange and second flange extending into the first wall panel and second wall panel. A cable is disposed between the first wall panel and second wall panel and attached to the first vertical support.

A wall support system is provided and includes an adjustable bracket system that attaches a bracket support beam to one or more of the traffic barriers. The adjustable bracket system includes two bracket members spaced apart by a top connecting member; where the top connecting member supports the bracket assembly straddled overtop the bracket support beam which is laid transversely atop one or more barriers. The bracket members are fastened to the barrier and tightened to the bracket support beam. This creates an adjustable system that can accommodate barriers of various cross-sectional widths and wall angles, to form a strong connection between a framework and the barriers.

Disclosed is an impact resistant traffic noise barrier system. The system includes a traffic barrier that is designed to be placed adjacent a roadway and next to a flow of traffic. The design and weight of the traffic barrier permit it to withstand a variety of vehicle impacts. As part of the system, a sound wall is installed along the top of the traffic barrier. The sound wall includes a series of beams that are secured to the traffic barrier via anchor plates. Acoustic panels are secured between adjacent beams. An anchor cable extends from an anchor post, to a first post, and along a number of intermediate posts. The anchor cable is thus suspended above the traffic barrier with the anchor cable being connected to the beams. As such, the anchor cable suspends the beams in the event they become separated from the traffic barrier.
