A traffic barrier and soundwall system is disclosed having wide-flanged [or H-posts] vertical posts oriented with a flange facing a roadway. Traffic barriers are located between them. The barriers have recesses at the intersection of their backs and ends. An angle bracket is positioned in the recess to separate the post from the barrier. A U-shaped strap has a base and a pair of arms extending from the base. Traffic barriers are positioned against the posts so that the angle brackets in the recesses are adjacent to the road-facing flange of the post. A strap fastener connects an arm of the strap to the recess of each of the adjacent traffic barriers. In this way, the base of the strap surrounds the rearward-facing flange of the post to secure the traffic barriers to the post. Sound barrier panels are located on the top of the traffic barriers, secured between the webs of the neighboring posts.

The present invention discloses a prestressed-bolted dry-assembled segmental precast hybrid tower with grouting-free, comprising a top steel tower tube, a reverse self-balancing steal-concrete transition section, and a prestressed-bolted dry-assembled segmental precast concrete tower with grouting-free dry fast splicing and a gear reinforced wind turbine foundation; the steel tower tube, the steel-concrete transition section, the concrete tower tube and the hollow wind turbine foundation are integrally connected from top to bottom through a prestressed steel strand system to improve the overall bending resistance of the tower; the upper end of the prestressed steel strands is anchored to the steel-concrete transition section, and the lower end is anchored to the bottom face of the wind turbine foundation corbel; the concrete tower tube is composed of a number of segmental tapered precast concrete tower segments, which are grouting free spliced vertically, and the vertical splicing utilizes positioning pins to accurately position the installation position. The prefabricated concrete tower tube segment is formed by a number of circular arc-shaped prefabricated concrete pipe segments with circumferential grouting free dry splicing. The segments are spliced into a whole by prestressed bolts and then installed staggered from top to bottom to enhance the shear resistance.

A wind turbine foundation structure comprising a hollow structural member having a longitudinally extending circumferential wall, the wall being bounded at the top by a top end face and bounded at the bottom by a bottom end face, wherein the wall is formed from a mineral building material and in that a wall thickness of the wall tapers from the top end face towards the bottom end face.

A system for mounting an anchor bolt to formwork or other structures associated with concrete construction includes a main body and latch coupled to the main body. The anchor bolt can pass through the main body and the latch can be moved so that threads formed in the latch engage threads formed in the anchor bolt to secure the anchor bolt in position as concrete is poured around the anchor bolt. The main body and the latch can have through holes for receiving a nail to lock the position of the latch with respect to the main body.

A method of reinforcing the tower base in existing guyed towers. A guyed tower is a tower supported by a base and guy cables. The tower's foundations are Base and Deadman anchors. The base is an isolated spread footing which is pier and pad or pile foundation. This method of reinforcing is a new mechanism to transfer part of the download on base to an alternative mat foundation.

The reason of using this mechanism is that the soil underneath the tower base is getting high stresses above its limit. The soil is getting overstressed due to some reasons that it happens frequently.

The standard procedure is before building any tower, the Geotechnical engineer does test boreholes at the proposed location of the tower foundations (Base Deadman Anchors). The geotechnical engineer provides the soil report with soil parameters at each borehole. The structural engineer designs the guyed tower and get the download on the tower base to design the spread footing (or pile). The download is the result of the dead load (tower own weight, mounts, antennas, microwave dishes, cables & equipment) and live load (wind & ice). The structural engineer designs the base to transfer the download from the tower to the soil safely based on the information that was given by the geotechnical engineer. In the future, if no change in loading, then the base will function well as designed, however the client always changes the dead load (antennas, microwave dishes, cables & equipment) and this is due to the fast-growing telecom technologies and the country needs. So, in most cases the base requires reinforcing.

The nonstandard procedure is to design the tower base, based on normal dry soil. Normal dry soil is a soil with average soil parameters values, this could happen due to short notice given by the client to the geotechnical engineer and the geo couldn't make it before designing the base. In this case the structural engineer designs the base with some assumed soil parameters and increasing the download to cover the absence of soil report (multiply download by factor more than 1.0, usually 1.20). Later after receiving the soil report, sometimes the soil parameters are weaker than the parameters that was used by the structural engineer. Here, the engineer must find the stresses on soil underneath the tower base and compare it with the soil report, if it was above the soil limit then reinforcing the base is required.

Something else which is the ice thickness, and this is defined by the ANSI-TIA-222. Telecommunications Industry Associations reviews the ice records and publish new list of the past 50 years of ice thickness. Also, they provide some changes on ice
