Slurry Shield Method of Constructing Underwater Slope Foundation
In the past few years, the slurry shield method has become increasingly popular with engineers constructing underground slope foundations. This method, also known as sprayed concrete or shotcrete, uses a pressurized series of pumps to apply a slurry of concrete to the surface of the exposed foundation. As the concrete dries, it bonds and forms a strong, solid foundation.
The main advantage of using slurry shields is the cost efficiency. Slurry shields take substantially less time to apply than conventional methods, such as using concrete blocks. The cost savings can often more than make up for the higher initial cost of using pumps and special concrete mixes. They also offer greater safety and consistency when constructing underground slope foundations.
In addition, slurry shields are relatively intuitive to operate. For example, experienced engineers can operate a single pump to apply multiple layers of concrete, up to a specified thickness, at a fairly consistent rate. During the application process, the engineer can carefully inspect the foundation and make any necessary adjustments to ensure a secure and even foundation.
The slurry shield method is also well-suited to a variety of conditions. It works best in medium-sized projects that have tight access requirements, or when soil can’t be stabilized via traditional methods. The installation process also requires minimal manpower, despite its complexity.
Given its versatility and cost efficiency, the slurry shield method is quickly becoming a go-to choice for engineers constructing underground slope foundations. In many cases, engineers are required to use slurry shields for projects that require an underground foundation, such as bridges and tunnels. As the method continues to evolve, its efficacy and cost-effectiveness will likely make the slurry shield the standard for constructing underground slope foundations.
