Trench Sheet Piles
Trench sheets are designed to support vertical faces of small to medium excavations. They are widely used in pipeline installation and temporary earth retaining systems, providing a safe working environment and efficient excavation support.
Installation Method
Trench sheets can be installed quickly using excavators equipped with quick release shackles through lifting holes located at the ends of the sheets. This allows fast positioning and removal during construction.
Driving is performed using a driving cap, which protects the sheet from damage during installation. During extraction, specialized clamps are used to prevent deformation and maintain sheet integrity.
Structural Function
Trench sheet piles are primarily used to support earth banks and prevent soil collapse during excavation. They ensure worker safety while maintaining stability in trenching operations.
Due to their structural design, trench sheets are especially effective for:
- Temporary excavation support
- Pipeline trenching
- Waterway bank protection
Reusability & Lifecycle
Trench sheets can be reused multiple times because they can be easily extracted without significant deformation. This makes them a highly economical solution for repeated construction projects.
Actual reuse cycles depend on:Sheet length，Soil conditions，Handling and extraction methods.
Profile Types & Connection
Steel trench sheets are available in different configurations:
- Overlapping trench sheets – without interlocks, simple connection
- Interlocking trench sheets – similar to traditional sheet piles with interlocks
Since trench sheets are produced using cold rolling technology, various profiles can be manufactured, including RC sections and other customized shapes.
Manufacturing & Customization
Trench sheets are manufactured using cold forming processes, allowing flexible production in terms of:Width,Height,Thickness,Length,Steel grade
👉 This flexibility enables precise adaptation to different project requirements.
