Kind Reader, do you know what construction walers are? If you’re not in the construction industry, you might not be familiar with this term. In simple terms, construction walers are horizontal beams that provide support to vertical piles during excavation. They are essential components in any excavation project and play a crucial role in ensuring a stable and safe working environment for workers. In this article, we will explore construction walers in detail and understand their importance in construction projects.
What are Construction Walers?
Construction walers are horizontal members that provide resistance to the lateral pressure exerted by soil or other structures. They are often used in conjunction with soldier piles, sheet piles, or shoring systems to support vertical or near-vertical excavations. Construction walers can be made from a variety of materials, including wood, steel, or precast concrete. They are commonly used in construction projects where deep excavations are required, such as basements, underground car parks, or tunnels.
Types of Construction Walers
Construction walers can be classified into two main types:
- Timber Walers: These are wooden members that are often used in conjunction with soldier piles. They are typically 6-12 inches wide and 12-24 inches deep. Timber walers are inexpensive, easy to handle, and can be cut to size on site. They are also easy to replace if they become damaged.
- Steel Walers: These are steel members that are commonly used in conjunction with sheet piles or shoring systems. They come in a variety of shapes and sizes, including H-beams, channels, and angles. Steel walers are stronger than timber walers and can span longer distances without the need for support. They are also more durable and can be reused on multiple projects.
Functions of Construction Walers
Construction walers serve several important functions, including:
- Providing Lateral Support: Construction walers are used to provide lateral support to the excavation. They resist the lateral pressure exerted by soil or other structures and prevent the excavation walls from collapsing.
- Distributing Loads: Construction walers distribute the load evenly across the excavation walls and prevent any one section from being overloaded.
- Transferring Loads: Construction walers can also be used to transfer loads from the excavation walls to other supporting structures, such as soldier piles or sheet piles.
- Providing a Work Platform: Construction walers can be used to provide a work platform for workers to stand on while working inside the excavation. This makes it safer and easier for workers to move around and perform their tasks.
Factors Affecting the Design of Construction Walers
The design of construction walers depends on several factors, including:
- Excavation Depth: The deeper the excavation, the larger and stronger the walers need to be.
- Soil Condition: The type and condition of soil surrounding the excavation can affect the design of walers. For example, if the soil is soft or has a high water content, larger and stronger walers may be needed to provide the necessary support.
- Structural Requirements: The design of walers must meet the structural requirements of the project, including any imposed loads or safety factors.
Types of Construction Walers
Depending on the specific use case, there are different types of construction walers that are commonly used in the industry. Here are some of the most popular types:
1. Single Waler
A single waler, also known as a single plate, is the most basic type of waler. As the name suggests, it consists of a single piece of timber or metal that is attached to the sheet piles or soldier piles. It provides a single point of contact to transfer the load from the soil to the wall system. Single walers are generally used in small-scale projects where load transfer requirements are minimal.
2. Double Waler
A double waler is similar to a single waler but consists of two pieces of timber or metal attached to the sheet piles or soldier piles. The top waler is usually placed further from the excavation, while the bottom waler is placed closer to the excavation. This results in a larger span, enabling it to provide greater stability to the retaining wall system. Double walers are commonly used in medium to large-scale projects where load transfer requirements are high.
3. Box Waler
A box waler is a type of waler that consists of a box-shaped cross-section. It is made up of two side plates and a top plate that are welded together to form a hollow box. Box walers are generally used in large-scale projects where heavy loads need to be supported by the retaining wall system.
4. Channel Waler
A channel waler is similar to a box waler but has a U-shaped cross-section instead of a box. It provides greater bending strength and torsional rigidity, making it suitable for larger, more complex projects that require greater load transfer capabilities.
5. I-Beam Waler
An I-beam waler is made up of a steel I-beam that is attached to the sheet piles or soldier piles. It is commonly used in large-scale projects such as bridges, highways, and high-rise buildings. It provides excellent bending stiffness and load-carrying capabilities, making it a popular choice for heavy-duty applications.
