A closer look at pipe bedding

Gravel | Latest News | Materials

Gravel for pipe bedding, the material laid below a pipe that supports it against the soil load, is a key material produced by wash plant users. We take a closer look.

Pipe bedding is a layer of material that is used to support and stabilise pipes in underground construction projects. It is placed around the pipes to help distribute the load and protect the pipes from external forces such as soil movement, vibration, and changes in temperature. Different grades of pipe bedding are used depending on the type of pipe, the soil conditions, and the load-bearing requirements of the project.

Stored gravel, used for pipe bedding

A number of factors need to be considered when selecting the appropriate grade of pipe bedding for a project. These include: the type of pipe being used, the diameter of the pipe, the soil conditions, and the expected loads on the pipe. Based on these factors, the pipe bedding is classified into one of several grades, each of which has specific requirements for the material, thickness, and compaction of the bedding layer.

In addition, there are also specialised pipe beddings that are used for specific types of pipes or in specific soil conditions.

How the pipe bedding production process works

Usually made of sand, gravel, crushed stone, or other materials that are suitable for the specific soil conditions and load-bearing requirements of the project, pipe bedding material can be produced by a wash plant installation, delivering a clean, graded material.

Raw aggregate is first fed into the wash plant. The aggregate is then washed to remove impurities and to separate the different sizes of material before drying. Once the raw aggregate is inside the wash plant, it is mixed with water and a cleaning solution and is subjected to a variety of physical and chemical processes to remove impurities and to separate the different sizes of material, including scrubbing, screening, and classification.

Once the washed and dried material has been produced, it can be used as the base layer for the pipe bedding.

Depending on the specific requirements of the project, the washed and dried material may be used as is, or it may be further processed to produce a specific size or grade of material. For example, the material may be screened to produce a specific size range or it may be mixed with other materials to produce a custom blend.

Meeting the materials shortage challenge with construction waste recycling

Meeting the materials shortage challenge with construction waste recycling

As the world’s population continues to grow and urbanise, there is a growing demand for building materials such as concrete and aggregates including gravel, crushed stone, sand and slag. This has led to a materials shortage in many parts of the world, resulting in higher prices, as well as a greater strain on the environment. However, there is a solution to this problem: using recycled materials to meet the demand for building materials, including aggregates.
