It is crucial to choose the right shoring system if you are involved with an excavation project. There are many shoring options available. Each one serves a different purpose. The best shoring system for you depends on many factors such as the soil conditions and how deep/larger your excavation will need to be. We will explain the different types of shoring systems as well as how they work to help you decide the best option for your needs.
Shoring
Shoring in excavation refers to the construction of temporary or permanent supports that are attached to an excavation’s sides. This is done to stabilize it and allow workers access. It depends on the depth of the excavation, soil type and purpose. Shoring can include installing wood braces or large steel walls. Shoring protects against cave-ins that can occur if the soil surrounding the excavation is not sufficiently supported. It also provides safe access for workers.
Shoring helps prevent cave-ins by keeping soil from rolling into excavations and providing additional support for heavy machinery used in excavation. Shoring is an essential part of any excavation project. It must be planned carefully and performed with care to ensure a safe and successful end result.
There are many types of shoe systems
Shoring is part a support system to trench faces. It prevents soil, underground utilities and roadways from moving. When it is impossible to slope back to the maximum allowed slope due to the depth or location of the cut, shoring or shielding may be used. Shoring is made up of posts, struts and sheeting. Two types of shoring exist: timber and aluminum hydraulic.
1. Hydraulic Shoring
Hydraulic Shoring is a prefabricated strut or wale system that is made of aluminum and steel. Hydraulic shoring is safer than timber shoring in that workers don’t have to go into the trench to install or take out hydraulic shoring.
The following are some other benefits of hydraulic systems:
- It is light enough to be easily installed by just one worker
- To ensure an even distribution of pressure along trench lines, the gauge is regulated
- Can their trench faces be “preloaded” so that the soil’s natural cohesion is used to stop movement
- It can be easily adapted to different trench depths and widths
All shoring should go from the top and be removed from the bottom. Hydraulic shoring should always be checked for leakage hoses or cylinders, cracked connections, bent bases and any other defective or damaged parts at least once per shift.
2. Pneumatic Shoring
Pneumatic shoring is similar to hydraulic shoring. Pneumatic shoring uses pressure from air, not hydraulic pressure. You will need an air compressor if you use pneumatic shoring. Air shoring uses compressed air to move the trench jacks.
Pins can be used to lock the jacks using the air type system. Air is injected into the Jacks to expand them in order to remove the trenching system. This allows for the removal of the pin. These jacks are more popular than hydraulic ones because they are less likely to leak fluids or cause other problems.
Other Protective Systems
Employees who work in the trench must be protected against cave-ins, as we mentioned previously. Contractors should excavate a larger area than the minimum. This creates a more pleasant working environment for the workers in the trench. Workers may be able to use this extra area to escape unexpected crises like falling objects or debris.
Shoring Contractors Los Angeles must also limit the number of workers allowed in the trench at any given time to reduce risk. Only those necessary to complete the task should be allowed into the trench. The braces and planks may be removed once the trench has been backfilled. Trench braces and vertical planks can be reused multiple times if properly installed and removed.
