I have a tunnel construction under a river project. My site conditions of water table depth 2 meters below riverbed. Soil type is sandy gravel with high permeability and the tunnel depth is 10 meters below riverbed. And my dewatering objective for lower the table by 5 meter's to allow safe tunnel excavation.So what will be of my dewatering method, design and operation for this to minimize risk of water 🌊 inflow and flooding. 1. How many deep well system, diameter and it's deepth s 2. Pump Capacity etc.

It's design and construction are truly inspiring for 192 concrete piles, 43 meters long and 1.5 meters in diameter, extend into the ground to transfer the load to the bedrock.
“The construction of the Burj Khalifa’s basement involved advanced deep piling techniques to ensure the stability of the world's tallest skyscraper. These deep piles were meticulously designed and installed to support the immense load of the building and withstand environmental stresses such as heavy winds and potential overloads. This foundational approach ensures long-term stability and safety, preventing any risk of structural failure due to these factors.” Certainly! Here’s a more detailed explanation of the real-world techniques and considerations involved in the basement construction of the Burj Khalifa: 1. Site Preparation and Excavation Geotechnical Analysis: Detailed geotechnical surveys provided crucial data about the soil composition, groundwater levels, and bedrock depth. This information was essential for designing the foundation system. Massive Excavation: Excavating the site involved removing approximately 60,000 cubic meters of earth. The excavation extended down to the bedrock, creating a large and deep pit. 2. Secant Pile Wall Construction: To support the excavation and prevent soil collapse, a secant pile wall was installed. This method involves drilling overlapping concrete piles into the ground, creating a solid barrier around the excavation site. Purpose: The secant pile wall helped to retain the surrounding earth and control groundwater ingress during construction. 3. Deep Pile Foundations Pile Design: The foundation utilized a combination of bored piles and a raft foundation. Bored piles, ranging from 1.5 to 2 meters in diameter and extending up to 50 meters deep, were drilled into the bedrock to anchor the building. Raft Foundation: Above the piles, a massive reinforced concrete raft, approximately 3.7 meters thick, was constructed. This raft distributes the building’s load evenly across the piles. 4. Reinforcement and Concrete Reinforcement: High-strength steel rebar was used extensively to reinforce the concrete, ensuring structural integrity under the immense load of the Burj Khalifa. Concrete Quality: High-strength concrete was used to withstand the significant forces applied by the building and the environmental conditions. 5. Waterproofing Membranes and Coatings: Advanced waterproofing membranes and coatings were applied to protect the basement from groundwater infiltration. This was crucial given the high water table in Dubai. Drainage Systems: A comprehensive drainage system was installed to manage any water that might seep into the basement, further safeguarding the structure. #BurjKhalifa #DeepPiling #FoundationEngineering #SkyscraperConstruction #StructuralStability #HighRiseBuilding #AdvancedEngineering #BuildingTheFuture #ConstructionInnovation #MegaStructures

Here are some key things to consider before finalizing a dewatering pumps solution: 1. *Flow rate and pressure requirements*: Determine the required flow rate and pressure to effectively dewater the area. 2. *Water table depth and soil conditions*: Understand the depth of the water table and soil conditions to select the appropriate dewatering method. 3. *Water quality and contamination*: Test the water for contaminants and consider treatment options if necessary. 4. *Power supply and fuel availability*: Ensure a reliable power supply or fuel availability for the pumps. 5. *Noise and environmental considerations*: Consider noise restrictions and environmental regulations when selecting pumps and designing the dewatering system. 6. *Maintenance and repair requirements*: Choose pumps with easy maintenance and repair access. 7. *Budget and rental options*: Consider the budget and explore rental options for dewatering pumps and equipment. 8. *System design and engineering*: Ensure proper system design and engineering to prevent issues like overpumping or underpumping. 9. *Monitoring and control*: Implement a monitoring system to control the dewatering process and prevent potential issues. 10. *Local regulations and permits*: Obtain necessary permits and comply with local regulations. By considering these factors, you can select the most appropriate dewatering pumps solution for your specific needs.

Here are some common formulas used for dredging site work: 1. *Dredging Volume (V)*: V = L x W x D (Length x Width x Depth) 2. *Dredging Rate (Q)*: Q = V / T (Dredging Volume / Time) 3. *Sediment Transport (Qs)*: Qs = Q x (1 - p) (Dredging Rate x (1 - Porosity)) 4. *Dredging Efficiency (E)*: E = (Qs / Q) x 100 (Sediment Transport / Dredging Rate) 5. *Cutter Suction Dredging Production (P)*: P = Q x (1 - p) x (1 - c) (Dredging Rate x (1 - Porosity) x (1 - Cutter Loss)) 6. *Hydraulic Dredging Production (P)*: P = Q x (1 - p) x (1 - h) (Dredging Rate x (1 - Porosity) x (1 - Hydraulic Loss)) 7. *Dredging Area (A)*: A = L x W (Length x Width) 8. *Dredging Path (DP)*: DP = L / (2 x sin(θ/2)) (Length / (2 x sine of half the included angle)) 9. *Dredging Time (T)*: T = V / Q (Dredging Volume / Dredging Rate) 10. *Sediment Density (ρ)*: ρ = M / V (Mass / Volume) Where: - L = Length of dredging area - W = Width of dredging area - D = Depth of dredging area - T = Time - p = Porosity of sediment - c = Cutter loss (percentage of sediment lost during cutting) - h = Hydraulic loss (percentage of sediment lost during transport) - θ = Included angle of dredging path - M = Mass of sediment - V = Volume of sediment Note: These formulas are simplified and may require additional factors and variables depending on the specific dredging project.
