When you are planning a project, it is necessary to take into account how you will retain excavation. Depending on the area, you will need to use different techniques to protect against the danger of cave-ins. In some cases, it is even required to stabilize the areas around structures. There are several options available, which include using a retaining wall or a pillar.
To create a retaining wall, a steel bar is inserted into the soil near the ground. This void is filled with grout and then a bearing plate is inserted into the center. Once the bearing plate is secured, a wire mesh reinforced shotcrete facing is added land clearing. The height of the soil nail wall can be up to six feet in increments of five feet. Each stage is completed until the final excavation depth is reached.
How Do You Retain Excavation?
Before excavation, it is important to identify the types of utilities that are present in the area. Moreover, it is essential to have a good knowledge of the area’s groundwater levels. If there is the high water table, your retaining structure will be ineffective. A geotechnical engineer will be able to assess the ground conditions and recommend an appropriate approach for your project. You can also get the services of an excavation specialist for your project, who will help you determine the best method to retain your excavation.
Another way to protect the areas around your excavation is to use benching. There are several types of benching available, such as simple benching and multiple-level benching. Both forms can serve to protect against cave-ins. However, you should ensure that you are not working underneath heavy equipment or in an environment with a high level of atmospheric deterioration.
Regardless of the method you choose to protect your excavation, you should always make sure that you have an exit route. Also, you should avoid working with heavy machinery at the sides of the trench. Otherwise, you may be trapped in the void.
