What is Hand Dug caissons:
- Hand-dug caissons are cylindrical shafts created through manual excavation. They are typically used as foundations for light to medium structures in situations where machine access is limited or where high precision is required.
Why is Hand dug casisson used :
- Hand-dug caissons are particularly suitable when:
- Machine access is restricted: In areas where large machinery cannot be used, manual excavation provides a viable alternative.
- Precision is essential: This method allows for careful, controlled excavation, making it ideal for projects where precision is crucial.
- The project involves light to medium structures, such as small buildings or extensions, where the load-bearing requirements can be met by hand-dug caissons.
How is hand dug caisson executed:
- The process of constructing hand-dug caissons involves several key steps:
- Manual Excavation: Workers manually dig the shaft to the required depth, carefully removing soil and other materials.
- Lining Installation: To prevent the walls of the shaft from collapsing, temporary or permanent linings are installed. These linings provide support and stability during the excavation process.
- Concrete Pouring: Once the desired depth is reached, the shaft is filled with reinforced concrete, creating a strong, stable foundation.
Where:
- North Soil Engineering Sdn. Bhd. has demonstrated its expertise in hand-dug caisson construction through several notable projects, including:
- Additional Classroom Level for Cempaka Group Sdn Bhd in Damansara, Kuala Lumpur: North Soil Engineering successfully completed the hand-dug caisson work for this project, providing the necessary foundation for the additional classroom level of a two-story building. The project required precision and attention to detail, which the company delivered effectively.
- Proposed Caisson Pile at Lot 962 in Mukim Bandar Cheras for Cheras Hong Soon Development Sdn Bhd: This project involved the construction of caisson piles, showcasing North Soil Engineering’s capability to execute hand-dug caisson works even in challenging environments. The company’s expertise ensured the structural integrity and success of the project.
