Effective Cave-In Protection Cave-ins are a major hazard in trenching operations, posing a significant risk to workers' lives. Effective cave-in protection is crucial to prevent soil collapse and ensure a safe working environment. Here are four methods of effective cave-in protection: ⏩ Shoring Systems Shoring systems are designed to support the trench walls and prevent collapse. They consist of steel plates, beams, or hydraulic shores that are installed in the trench to provide a stable barrier between the soil and workers. ⏩ Trench Boxes (Trench Shields) Trench boxes, also known as trench shields, are protective barriers that are placed in the trench to prevent soil collapse. They are typically made of steel or aluminum and are designed to withstand the weight of the surrounding soil. ⏩ Shielding (Sheet Piling or Soldier Beams) Shielding involves installing a physical barrier, such as sheet piling or soldier beams, to prevent soil movement and cave-ins. This method is particularly effective in unstable soil conditions. ⏩ Sloping and Benching Sloping and benching involve excavating the trench at a safe angle to prevent soil collapse. This method is effective in stable soil conditions and can be used in combination with other methods for added protection. These four methods are effective in preventing cave-ins and ensuring a safe working environment in trenching operations. It's important to assess the soil conditions and trench configuration to determine the most appropriate method or combination of methods to use. Remember, safety is everyone's responsibility! #WorkplaceSafety #ConstructionSafety

Excavation Protection types ? 1. Sloping: Sloping involves cutting back the sides of the excavation at an angle to create a stable slope. The angle of the slope depends on the soil type, depth of the excavation, and other factors. Sloping helps to prevent cave-ins by providing a gradual and stable incline. 2. Benching: Benching is similar to sloping but involves creating a series of horizontal steps or benches in the excavation walls. Each bench provides a level surface with a vertical face, reducing the risk of a collapse. The depth and width of the benches depend on the soil conditions and the requirements of the specific excavation. 3. Shoring: Shoring is the installation of temporary support systems to prevent soil movement and cave-ins. It involves using materials such as timber, steel, or hydraulic supports (shoring jacks) to brace the excavation walls. Shoring systems are designed based on soil conditions, depth of the excavation, and the surrounding environment. 4. Shielding: Shielding involves the use of protective structures or trench boxes to provide a safe working area within the excavation. Trench boxes are made of steel or aluminum and are placed in the trench to protect workers from cave-ins. They are installed in sections as the excavation progresses. 5. Hydraulic Excavation Support Systems: Hydraulic excavation support systems use hydraulic pressure to support the excavation walls. These systems typically consist of hydraulic struts or jacks that exert pressure against the excavation walls to prevent collapse. They are commonly used in situations where space is limited and traditional shoring methods are not feasible. 6. Soil Stabilization: In some cases, soil stabilization techniques may be employed to improve the stability of the excavation. This can involve methods such as soil nailing, grouting, or the use of geotextiles to reinforce the soil and prevent movement. It's important to note that the specific type of excavation protection used will depend on various factors, including soil conditions, depth of the excavation, and local regulations. A qualified engineer or safety professional should assess the site and determine the appropriate excavation protection measures to be implemented. #Constructionsafety #excavationsafety

EXCAVATION: Is a man made Cut or Cavity formed by removal of soil either mechanically or manually. There are many hazards in excavation but today let's focus on Cave- In. Excation/ Cave-In protection methods. 1. Sloping: Involves cutting back the trench walls of an angle inclined away from excavation. 2. Benching: Involves creating a series of benches on the excavation wall. 3. Shoring: Involves installing supports to prevent soil movement. (There are different types of Shoring) ●Hydraulic Shoring: Involves using hydraulic pistons that can be adjusted for tightening. ●Pneumatic Shoring: Similar u Hydraulic Shoring but it Involves using air bags. ●Timber Shoring: Uses timber to create a support system. 4. Shielding: Involves using trench boxes or other types of support to protect workers from cave-in( unlike Shoring which prevents soil movement. Shielding is done to protect workers if a cave in occurs). Before an excavation is carried out a soil stability assessment should be done and the type of soil also known. Types of soil and their safety excavation angle. ▪︎Solid Rock: 90° ▪︎Type A Soil (Clay): 53° ▪︎ Type B Soil ( Sand & Gravel) : 45° ▪︎ Type C Soil ( Loose Soil) : 34°

the risks of working in excavated area are very high. this activity need to be carried out with all required permits and excavation procedures in place.

To understand the ground stability is essential while working on the field, and take preventive measures.

The concrete eaters... A hydraulic concrete crusher excavator attachment is a demolition tool used to break concrete structures. It connects to an excavator's hydraulic system, using the hydraulic fluid to power its jaws. The attachment consists of two jaws: a fixed one and a moving one, which is controlled by the excavator's hydraulics. When the moving jaw closes, it crushes the concrete between the jaws. This tool is effective for demolishing buildings, bridges, and other concrete structures, as it can handle reinforced concrete and other tough materials. Its use improves efficiency and safety on demolition sites by reducing the need for manual labor and providing precise control over the demolition process. video rights : respective owners DM for removal / credits #demolition #concrete #construction #engineering #civilconstruction #civilengineering #engenhariacivil #engenharia

What is relining and is it suitable for your needs? Relining is a method of trenchless repair suitable for virtually all pipe compositions. It allows for the repair of defects without the need to excavate. This method is widely practiced and approved to the highest quality standards. How is it done? Our preferred method is performed by firstly saturating the liner with a resin. We then insert the liner into a device that turns the material inside out as it installed into the pipe inverted. Inversion lining, as opposed to pull through lining means that the liner may be installed through only one opening. Essentially, in the majority of cases, only one manhole need be exposed to install the liner. We can shoot to a stopping point without digging up or accessing the other end. This method is used as installation lengths may be longer than the pull-in-place method. With enough air capacity, you install virtually any length you need. Getting around bends using this method is also more possible than pull-in-place lining. Once the liner is cured with UV light, it is fully hardened. Following this process, we can carry out an integrity test to ensure any prior areas of issue have been fully repaired. If you have any projects you'd like us to review for lining, at no obligation, contact us today on 01 5166537 or info@tankenvironmental.ie

The achievable tolerances of #bearingpiles are strongly related to factors such as ⤵️ ➡️ The accuracy in setting up the #piling equipment ➡️ The accuracy or ‘repeatability’ of the measurement system ➡️ The fixity in machine parts ➡️ Any presence of obstructions in the ground and any variations in the properties of the soil, especially near the point of entry of the pile into the ground surface ➡️ The inclination of the strata ➡️ Operator error
