Sheet pile drive

What is a sheet pile?

Sheet piles are a device with a linkage on the edge. Steel sheet pile is a type of steel with a lock. Its cross-sections include straight plate, groove and Z-shaped, etc., and are available in various sizes and interlocking forms. Common ones include Larson steel sheet pile , Lackawanna type, etc. The types of steel sheet piles include cold-formed steel sheet piles and hot-rolled steel sheet piles.

What is the purpose of a sheet pile?

Steel sheet piles are long structures made of steel plates that are used to reinforce and support soil and building structures. Specific functions include:

1. Protect the building structure: Steel sheet piles can protect the foundation of the building from erosion when the building structure is fully fixed.

2. Guide isolation walls, cofferdams, etc.: During the construction process of isolation walls, cofferdams, etc., steel sheet piles are needed to reinforce the soil and prevent cement penetration.

3. Support deep foundations, retaining walls, etc.: In projects such as deep foundations and retaining walls, steel sheet piles are needed to reinforce and support the soil and building structures.

4. Increase the elastic modulus: When fixing buildings, steel sheet piles can increase the elastic modulus of the building, thereby reducing the risk of earthquakes in the building.

What is sheet pile driving?

In order to make the foundation of the building strong, steel sheet piles, etc. are driven into the ground.

What is the sheet pile driving method?

1. Impact piling method

Impact piling method, also known as stamping piling method, is a commonly used steel sheet pile construction method. By using an impactor to continuously impact the steel sheet piles into the ground, the purpose of fixing and reinforcing the soil is achieved. It has the characteristics of fast construction speed and low cost, and is widely used in fields such as house foundations and dam construction.

2. Vibration piling method

The vibration piling method uses a vibrator to vibrate the steel sheet piles so that they gradually enter the ground and achieve the purpose of fixing and reinforcing the soil. This construction method has the characteristics of low noise, low vibration and high construction efficiency, and is suitable for noise-sensitive areas and soft soil layers.

3. Static piling method

Static piling is a common method of driving steel sheet piles. By exerting a certain static force,

The steel sheet piles are gradually driven into the ground. The specific steps are as follows:

1) Dig a hole at the pile location to ensure that the bottom of the hole is flat;

2) Place the steel sheet pile into the dug hole so that it fits closely with the hole wall;

3) Use a large press or hydraulic press to apply appropriate static force to gradually press the steel sheet pile into the

underground;

4) Check the verticality and pile top elevation of the steel sheet pile to ensure it meets the design requirements.
