Project situation:

Project:Jiaxing-Shaoxing Sea-Crossing Bridge
Users: MBEC Bridge project & CCCC
Quantity:4 sets
Jiaxing-Shaoxing Sea-Crossing Bridge is an cable-stayed bridge with six pylons and with main span 2680M. The bridge is a two-way expressway with 4 lanes each and the width of the bridge is 55.6M.
The geological feature of this area is high-strength sandy soil.
In this project we use the world's largest drilled piles in the bridge.The drilled piles with the Diameter 3.8M were used in large quantities.The depth of the drilled piles driving is 40M.The filling quantity of the single concrete filling pile is more than 1300M3.

Vibratory hammer is designed as per resonance theory.When the pile forcing vibratory is consistent with the soil vibratory frequency,the soil will occur resonance phenomenon.Meanwhile ,the largest amplitude,sufficient vibratory frequency and acceleration will break the cohesion between the soil and pile.In that case the pile will disintegrate from the soil in a short time.Pile-sinking resistance especially side resistance will be reduced very quickly. Then the pile sinks under the gravity.Depend on reducing the friction between the pile and the soil to sinking the pile.So it is effective to extract the pile only using a little more force than the pile self weight.As a result ,the vibratory hammer develops rapidly and broadly used in pile-driving and pile-pulling construction.
