Architectural Tension Bar For Construction High Strength Steel Tie Rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650.

Hunan Yueyang verifies Dongting Lake’s recent death is actually 6 heads of finless porpoise
Hunan Yueyang verified that the recent death of the finless porpoise in Dongting Lake was actually 6 diesel generators | Diesel Generator Price / 2012-04-20
According to an anatomy survey conducted by the Institute of Hydrobiology, Chinese Academy of Sciences, the cause of regional continuous death of finless dolphins in Dongting Lake has been partially identified. In the next step, Yueyang will select specific areas of Dongting Lake that are in good ecological condition and suitable for the survival of finless porpoises, and explore measures for ex situ conservation of finless porpoises.
Recently, the relevant media reported that a continuous finless porpoise death occurred in Dongting Lake since March. The number of finless porpoises that died in the waters of Dongting Lake was verified by the fishery authorities of Yueyang City.
The six finless porpoises that died were: On April 9th, a finless porpoise was found lying across the waters of Lusheng Farm, the old port of Lujiao, Yueyang County. The finless porpoise has now been dissected and refrigerated. On April 13, a dead finless porpoise was found in the waters of Yanzizhou, Lujiao County, Yueyang County, and it has now been refrigerated. On April 14th, 3 finless porpoises were found in the waters below Taipingzui and North Gate crossing in Yueyang County (after anatomy, one of the female finless porpoises was found to harbor a finless porpoise), and two of them have been dissected and buried, and the other one has been carried out. refrigeration. On April 15, a dead finless porpoise was found in the waters of Yanzizhou, Lujiao County, Yueyang County, and it has now been refrigerated.
On the afternoon of April 16, Yueyang City transported two finless porpoises that died on April 14 and 15 and an angling fin on April 9 to the Institute of Hydrobiology (Wuhan) of the Chinese Academy of Sciences for anatomical investigation of the cause of death.
On the morning of the 17th, the Institute of Hydrobiology, Chinese Academy of Sciences (Wuhan), autopsied and dissected two of the dead finless porpoises. The anatomical report concluded that the skull on the left side of the left side of a finless porpoise was clearly cut by sharp instruments, and it was speculated that it might be hit by a propeller and cause death. In the other body, no obvious injuries were found on the body surface. The main internal organs such as the liver and lungs were rotted. No obvious pathological changes were visible. The cause of death was temporarily unclear. Whether there was a possibility of death caused by pesticide poisoning or water pollution still remained. Tissue samples of pesticides and heavy metals were monitored.
Yueyang City Animal Husbandry and Aquatic Products Bureau stated that in the next step, Yueyang will organize scientific research on finless porpoise conservation, select specific areas of Dongting Lake that are in good ecological condition and suitable for the survival of finless porpoises, implement ex situ conservation programs for finless porpoises, and preserve and expand the population of finless porpoises. In addition, the protection of the finless porpoise will be further strengthened from the aspects of strengthening the protection function of the finless porpoise, strictly controlling the fishing intensity of the fishery, advancing the comprehensive management of the Dongting Lake, and strengthening the law enforcement management of the fishery team.
