The Haikou overpass is located on the Haikou turntable of Jinshan Avenue. It is a box girder structure and has a variant cloverleaf shape from the outside. There are 6 up and down ramps, nearly 3.7 kilometers. The design speed of the ramp is 40 km/h.
The project adopts KET-SMTB-12 intelligent control synchronous lifting hydraulic system of Canete Company, and is equipped with 36 sets of KET-RSM-1000 ultra-thin hydraulic jacks to meet the continuous synchronous lifting of five spans and one connection on site, so as to realize Synchronous control at 12 o'clock.
