Shanghai Zhenzhong Vibration Hammer: Assisting in the Deep Foundation Treatment Project of Dalian Jinzhou Bay International Airport

Project Overview:

The terminal area of Dalian Jinzhou Bay International Airport is 500000 square meters, with 198 parking spaces on the civil aviation apron; The north runway is 3600 meters long and 45 meters wide, while the south runway is 3400 meters long and 45 meters wide; It can meet the demand for an annual passenger throughput of 43 million, a cargo and mail throughput of 550000 tons, and 328000 aircraft takeoffs and landings; It is a 4F international airport and regional aviation hub. The construction process of Dalian Jinzhou Bay International Airport, as an important transportation hub in Northeast China, has attracted much attention. Among them, deep foundation treatment engineering (terminal area) is a key link to ensure the stable operation of the airport.

Project Introduction:

Project Name: Dalian Jinzhou Bay International Airport Deep Foundation Treatment Project (Terminal Area)

Construction Unit: Dalian International Airport Group Co., Ltd

Construction Unit: Joint Venture of China Construction Eighth Engineering Division Co., Ltd., China Construction Infrastructure Co., Ltd., and Shanghai Port Infrastructure (Group) Co., Ltd

Construction content: Deep foundation treatment of terminal area

Deep foundation treatment area: approximately 800000 square meters

Construction technology: Vibration immersed gravel pile

Pile diameter: 1.2 meters

Pile length: 30 meters

Geology: 20-26-meter backfill and riprap layer

Construction equipment used: resonance free electric drive large eccentric moment vibration hammer with walking pile frame

Equipment models: EP550C/JZB270 and EP320T/JZB240

EP550C main parameters: motor power: 400kW, eccentricity: 400kg. m, vibration impulse: 30150N. s

EP320T main parameters: motor power: 240kW, eccentricity: 250kg. m, vibration impulse: 17270N. s

As an advanced foundation treatment equipment, Shanghai Zhenzhong resonance free electric drive large eccentric moment vibration hammer provides strong support for the foundation treatment of Dalian Jinzhou Bay International Airport with its efficient and precise operational performance. During the construction process, the vibration hammer was successfully applied to compact and reinforce the deep backfill and stone layer, effectively improving the bearing capacity and stability of the foundation. This application not only demonstrates the outstanding performance of Shanghai Zhenzhong vibration hammer in large-scale engineering projects, but also further proves its leading position in the field of foundation treatment. With the continuous advancement of the Dalian Jinzhou Bay International Airport project, we will continue to provide reliable technical support for more similar projects and help promote the sustainable development of China's transportation infrastructure construction.
