Many building and construction projects around the UK (and around the world, for that matter) have been making use of various materials and components for years. Today’s technological advancements have made it a lot easier for architects, engineers, and contractors to create even more robust and durable structures and other building elements, and with the technology we have, construction is faster and even safer as well. But there is one kind of component that is increasingly being used in numerous construction and building projects, and the king post wall has indeed proven its effectiveness in many ways. But what exactly is it, and what can you expect from using such a component? What are its top uses and benefits? Here’s what you need to know about king post walls and how you can maximise their use for your specific project
- The basics on king post walls
King post walls are also referred to as soldier piles, and it may interest you to know that they are one of the oldest kinds of retaining wall systems. They have been used for years, particularly when dealing with deep excavation. In fact, the king post wall has been around since the latter part of the 1800s, and it has been widely used in major cities like London, Berlin in Germany, and New York in the US.
- Their design
The king post wall is an isolated column made of steel, and you can have it installed along the proposed line of your retaining wall system. You can install it at centres with space lengths of between one to three metres, and you can then fill the space in between each king post. The space is filled over the height of the wall with various solutions, including a precast panel made of concrete.
If you are looking for the best king post wall selection that can fit your requirements, make sure it is made according to British standards or Eurocode (7) standards. You can utilise them both temporarily and permanently, depending on the kind of project you may have. King post walls can last for decades – in fact, the lifespan of a king post wall can extend to up to 50 years.
- Their installation
One of the main aspects of king post walls that make them a viable choice is their ease of installation. The method or process involves hole-drilling using a mini piling rig or CFA large-diameter rig. Once the workers drill the holes, you can fill them with concrete and install an H beam. With this, you can have the precast panels inserted or placed in between the H section webs, and upon excavation, you will already have finished and fully embedded walls.
- Their advantages
There are numerous advantages presented by king post walls, one of which is their fast construction, as mentioned. But they are also cheaper compared to other materials or components used for retaining walls such as concrete piled or sheet piled walls.
The process of installing these walls is also versatile, and you can readily make adjustments right on-site to accommodate various changes. You can use your king post walls for different applications that entail retention. They are often the best option if you are dealing with different ground or soil conditions (especially hard or rocky ground).
