In recent years, with the development of the national economy, port loading and unloading of large objects gradually increased. Only in 1986, Tianjin Port handled more than 50,000 tons of bulky items for Beijing Capital Steel. In March 1986, a refinery tower made by Japan for Tianjin Petrochemical Company was unloaded at the southern suburbs of Tianjin’s Haihe River. The southern suburbs of the pier design, construction, panel thickness of only 10-12cm, plate force bar for φ9 @ 17cm. In accounting the terminal can withstand 139 tons of heavy-duty trailers and heavy objects 158 tons, the port engineering specifications “JTJ220-82” is not used, but the use of
