NANJING WANHUI NEW MATERIAL TECHNOLOGY CO.LTD

Our company is an integrated high-tech enterprise, which manufactures various types of Cold formed steel sheet piling, and brings R&D, production, sales, construction and rental altogether. Our products are widely used domestically and overseas including key national projects, which have received good receptions from construction, and practical applications.

Sheet piling consists of a series of panels with interlocking connections, driven into the ground with impact or vibratory hammers to form an impermeable barrier

The following are some of the more common geotechnical and environmental applications in which sheet piling is extremely effective.

Ø         Cofferdams

Ø         Ground Water Diversion/Control

Ø         Barrier for Ground Water Treatment Systems

Ø         Retaining Walls

Ø         Containment Walls

Ø         Flood Protection

Ø         Coastal Protection

There are a number of ways to install sheet piles. The methods are

1.   Using a vibratory hammer

2.   Hydraulic powered drop hammer

3.   Diesel power drop hammer

4.   Hammering with the bucket of an excavator (Not recommended as this can damage the sheet piles and the excavator bucket)

Starting with the vibratory hammer, the sheet piles are first grabbed with the hammer jaws. Once in position, the sheet piles are installed using vibration.

The vibration produced by the vibratory hammer is used to loosen the soil and allowing the installation of the sheet pile through penetration into the ground with it’s own and the hammer’s weight.

The vibratory hammer is usually powered by large electric motors. The vibratory hammer is usually hoisted using a crane. Sammler vibratory hammer can be adapted to an excavator boom.

Sometimes for short length sheet piles of about 6 to 8 meters can be installed using a small hydraulic powered vibratory hammer attached to a heavy excavator. The bucket of the excavator had been removed and in its place a vibratory hammer is placed. It will be powered by the hydraulic system of the excavator.
