Larsen steel sheet piles
Versatile Engineering Applications – Larsen steel sheet piles are widely used as retaining walls for soil, water, and sand in bridge cofferdams, large pipelines, temporary excavations, docks, and embankment protection, making them essential for many construction projects.
Efficient and Cost-Effective Construction – They allow for fast installation with lower construction costs, providing a practical solution for both temporary and permanent structures.
Excellent Environmental and Waterproof Performance – With strong water-sealing ability, these sheet piles are reliable in preventing leakage, while also being environmentally friendly in application.
Flexible Production Options – Available in both cold-formed and hot-rolled types, with cold-formed piles offering greater cost advantages, they can be used interchangeably to meet diverse project requirements.
Larsen steel sheet piles, also known as U-shaped steel sheet piles, are a new type of building material. They are used as retaining walls for soil, water, and sand in bridge cofferdams, large pipelines, and temporary ditch excavations. They also serve as retaining walls, retaining walls, and embankment protection at docks and loading docks, playing a vital role in engineering projects. Larsen steel sheet piles for cofferdams are not only environmentally friendly but also fast and inexpensive to construct, offering excellent waterproofing.
Based on the production process, the product is categorized into two types: cold-formed steel sheet piles and hot-rolled steel sheet piles. Cold-formed steel sheet piles offer a more cost-effective solution in construction projects, and the two types can be used interchangeably.
Steel sheet piles are a type of steel with a locking mouth. Their cross-sections include straight plate, grooved, and Z-shaped, and they come in various sizes and interlocking forms. Common types include Larson type and Lackawanna type. Their advantages are: high strength and easy to drive into hard soil layers; they can be constructed in deep water and, if necessary, can be added with inclined supports to form a cage; they have good waterproof performance; they can be formed into cofferdams of various shapes as needed and can be reused many times. Therefore, they have a wide range of uses. (1) Cold-formed steel sheet piles include non-interlocking cold-formed steel sheet piles (also known as channel plates) and interlocking cold-formed steel sheet piles (divided into L-type, S-type, U-type, and Z-type). Production process: Thinner sheets (usually 8mm to 14mm thick) are continuously rolled and formed in a cold-formed unit. Advantages: Low investment in the production line, low production costs, and flexible product length control. Disadvantages: The thickness of each part of the pile body is the same, and the cross-sectional dimensions cannot be optimized, resulting in an increase in steel consumption. The shape of the locking part is difficult to control, the joints are not tightly locked, and water cannot be stopped. The pile body is prone to tearing during use.
(2) Hot-rolled steel sheet piles The world's hot-rolled steel sheet piles mainly include several major categories and dozens of specifications, such as U-type, Z-type, AS-type, and H-type. The production, processing and installation processes of Z-type and AS-type steel sheet piles are relatively complex and are mainly used in Europe and the United States; in China, U-type steel sheet piles are mainly used. Production process: The piles are formed by high-temperature rolling using a steel rolling mill. Advantages: Standardized dimensions, superior performance, reasonable cross-section, high quality, and the locking joints have strict water-proof properties. Disadvantages: High technical difficulty, high production costs, and inflexible specification series.
Advantages of sheet piles
1. The bearing capacity is strong, the structure is light, and the continuous wall composed of steel sheet piles has high strength and rigidity.
2. The water tightness is good, and the joints of the steel sheet piles are tightly combined, which can naturally prevent seepage.
3. The construction is simple, can adapt to different geological conditions and soil quality, can reduce the amount of earthwork for excavation of the foundation pit, and the operation takes up less space.
4. Good durability, depending on the use environment, the life span can be as long as 50 years.
5. The construction is environmentally friendly, and the amount of soil borrowed and concrete is greatly reduced, which can effectively protect land resources.
6. The operation is efficient, and it is very suitable for the rapid implementation of disaster relief and prevention such as flood control, subsidence, quicksand, and earthquakes.
7. The material can be recycled and used repeatedly. In temporary projects, it can be reused 20 to 30 times.
8. Compared with other single structures, the wall is lighter and has greater adaptability to deformation, which is suitable for the prevention and treatment of various geological disasters.
Larsen steel sheet piles have a wide range of uses. In permanent structural buildings, they can be used for docks, unloading yards, embankment revetments, retaining walls, retaining walls, breakwaters, diversion dikes, docks, gates, etc.; in temporary structures, they can be used for mountain closures, temporary bank expansions, river interruptions, bridge cofferdams, large pipeline laying, temporary ditch excavation, soil, water, and sand retention; in flood control and rescue operations, they can be used for flood prevention, collapse prevention, and quicksand prevention.
