Abstract: 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.

Abstract: A sound barrier wall has a plurality of footings spaced apart and vertical “I” beam wall stiffeners mounted to the footings. Alternatively, the vertical wall stiffeners are mounted to a crash barrier. A horizontal wall stiffener can be disposed between the adjacent vertical wall stiffeners. A plurality of wall panels is vertically stacked between adjacent vertical wall stiffeners. Each wall panel includes a sound insulating block, and plurality of support members disposed on opposite sides of the sound insulating block for providing structural support. Each support member has a head portion in contact with a surface of the sound insulating block and a stem portion extending into the sound insulating block. An “I” beam can be disposed between the vertically stacked wall panels. A top cap is mounted over the vertically stacked wall panels and protective layer is formed over the wall panels and vertical wall stiffeners.

Abstract: Extendable trailer apparatus includes a fixed frame and a frame slidably connected to the fixed frame and movable relative to the fixed frame for lengthening and shortening the trailer apparatus. The movable rear frame includes an axle and wheels secured to it, and a load is secured to the fixed frame. The two frames are movable for adjusting the weight of the load on trailer axles including axles secured to the fixed portion of the trailer and an axle or axles secured to the movable frame. One embodiment of the apparatus includes an end dump bed with tapered sides and a sloping bottom for enhancing the dumping capabilities.
