Shanghai Zhenzhong resonance free variable frequency torque vibration pile hammer assists Shanghai Outer Ring Elevated Traffic Function Improvement Project

1、 Project Name: Shanghai Outer Ring Road East Section (Huaxia Middle Road Longdong Avenue) Traffic Function Enhancement Project

2、 Construction site: S20 Outer Ring Road East Section and Huaxia Middle Road Elevated Hub

3、 Construction Overview: In order not to affect normal traffic, a steel access road needs to be built next to the existing elevated road to ensure the normal passage of vehicles. The construction location of the steel access road is small in space and close to the original elevated road. Based on the principle that pile driving construction should not affect the foundation of the original road piers, high requirements are placed on construction safety and environmental protection.

4、 Geological conditions: The soil is composed of clay and silty clay, and the geological conditions within the bottom elevation range are unstable. The depth of pile sinking varies from 35-45m below the surface.

5、 Construction equipment:

truck crane

Shanghai Zhenzhong EP120 resonance free eccentric torque stepless adjustable vibration pile hammer

In the vertical state of the steel pipe pile, the vibration pile hammer is lifted and positioned by a truck crane. As the operator starts the vibration pile hammer control cabinet, the steel pipe pile begins to slowly sink. When the steel pipe pile sinks to the designated elevation, it stops sinking and stands steadily. The entire process of "starting", "sinking", and "stopping" of steel pipe piles has low noise and small vibration. By controlling the infinitely adjustable eccentric torque device, the size and amplitude of the eccentric torque of the resonance free vibration hammer can be easily adjusted, achieving "zero" starting and "zero" stopping, overcoming the resonance damage caused by ordinary vibration hammer starting and stopping. Ensure the safe and reliable use of construction equipment; It also protects the foundation of the existing elevated bridges on both sides, achieving ideal pile forming speed and efficiency, which is both economical and environmentally friendly!

The EP series vibration pile hammer pile sinking construction this time is a construction technology commonly used in Beilei Pian Road and Bridge. Generally, small EP series vibration pile hammers can be used.

Advantages of using EP series resonance free eccentric torque infinitely adjustable vibration pile hammer:

1. High construction efficiency: A steel pile that is 30-40 meters high can sink to the designated elevation in 10-20 minutes. The EP series vibrating pile hammer can easily adjust the eccentric moment to change the amplitude, achieving ideal pile sinking and extraction speed and efficiency according to the requirements of different soil layers.

2. Small site limitations: In limited construction sites, the EP series vibrating pile hammer can be flexibly operated by a truck crane to lift and drive piles quickly and conveniently.

3. Construction economy: The use of EP series vibrating pile hammers can reduce start-up energy consumption and achieve start-up in a "zero" eccentric moment state without the need for a large capacity power supply. ”Zero "start and" zero "stop overcome the resonance generated when starting and stopping with eccentric force distance, avoiding the occurrence of damage to other equipment components caused by resonance, extending the service life of various parts of the equipment, and effectively protecting the crane and existing building foundation.

The resonance free eccentric torque stepless adjustable electric drive vibration pile hammer assists in the construction of the Shanghai Outer Ring Elevated Traffic Function Improvement Project, which is a green city construction project participated by Shanghai Zhenzhong in the municipal engineering construction of Shanghai city. The smooth implementation of the project in the city center is a recognition and support for the performance of our company's products.

Shanghai Zhenzhong will continue to adhere to the spirit of craftsmanship, relying on strong research and development and production capabilities, excellent management and service capabilities, based on scientific research and innovation, and committed to making our products better and stronger, contributing to the country's green and environmental protection construction cause!
