Liukukappale

Liukukappale, also known as a slipform or slip mold, is a construction technique used to create large, vertical, and hollow concrete structures. The process involves pouring concrete into a mold that is continuously lifted and moved upwards as the concrete sets, allowing for the creation of a vertical surface. This technique is particularly useful for constructing large-scale structures such as bridges, tunnels, and high-rise buildings.

The slipform process begins with the construction of a temporary formwork, which serves as the initial mold for the concrete. As the concrete is poured, a slipform paver is used to create a smooth, vertical surface. The paver is then lifted and moved upwards, allowing the concrete to set and form the desired shape. This process is repeated until the entire structure is completed.

One of the key advantages of the slipform technique is its ability to create large, hollow structures with minimal material waste. The process also allows for the creation of complex shapes and designs, making it a versatile option for various construction projects. Additionally, slipforming can be used to create structures with a smooth, finished surface, reducing the need for additional finishing work.

However, the slipform technique also has some limitations. The process requires specialized equipment and skilled labor, which can increase the overall cost of the project. Additionally, the technique is best suited for large-scale structures, and may not be practical for smaller or more complex projects. Despite these limitations, slipforming remains a popular and effective construction technique for creating large, vertical, and hollow concrete structures.
