The total length of the project is 8.6 kilometers and the length of the bridge is 5,126 kilometers. It is expected to be completed in 2024. The project volume is large and the construction period is urgent.
The pile foundation support on the north bank of the Ganjiang River adopts Doosan DX500 excavator and the S650 pile driver produced by our company for construction.During the construction period in July, the local area continued to be hot, with an average outdoor temperature of 38 degrees Celsius, and the surface temperature of the fuselage of the pile driver under the sun was close to 70 degrees Celsius. The average daily working time of the Juxiang pile driver was more than 10 hours. The temperature was not too high during the entire construction period, and the steel plate pile support construction task was completed on time and with quality assurance.
Juxiang S650 pile driver has an excitation force of 65 tons and a rotation speed of 2700 per minute. It has a unique patented heat dissipation design. It has the advantages of stable work, low noise and no high temperature. The soil quality of the pile foundation site on the north bank of the Ganjiang River of Ziyun Bridge is the upper silted sandbar and the lower gravel riverbed. The geology and water content are large. The average time for 9 Milason steel plate piles is about 30 seconds, and the driver can meet the piling intensity by using first-level vibration throughout the process.During this construction, the excellent work performance of Juxiang pile driver was praised by the construction party and Party A.
