Best Piling method for Deep Excavation Projects

Solid Foundations in Challenging Soils: The Art of Bored Pile Construction A bored pile, or drilled shaft, is a deep foundation type created by drilling a hole into the ground and filling it with concrete. This method is ideal for projects requiring strong, stable foundations in challenging soil conditions. The process begins with drilling a cylindrical hole to the required depth. A reinforcement cage is then placed inside, followed by concrete pouring. In waterlogged or unstable soils, bentonite slurry is often used to stabilize the borehole walls. The slurry supports the excavation and prevents collapse until the concrete is poured, often using the tremie method to avoid contamination. Bored piles are commonly used in high-rise buildings, bridges, and heavy structures, providing excellent load-bearing capacity and lateral resistance.

Diaphragm Walls: The Backbone of Deep Excavation Stability Diaphragm walls are robust vertical structures used in deep excavations to provide stability and support. Constructed from reinforced concrete, they are built by excavating a trench and then filling it with concrete, often supported by steel reinforcement. These walls serve as barriers against soil movement and groundwater infiltration, making them essential in projects like underground stations, basements, and deep foundations. They are particularly effective in soft or unstable soil conditions, where traditional shoring methods may be inadequate. Diaphragm walls can be installed using various techniques, including slurry trenching, which helps prevent collapse during construction. Their strength and ability to retain soil and water make them crucial for maintaining excavation safety and integrity. video rights : Respective owners DM for removal/credits #diaphragmwalls #excavation #geotechnical #civilengineering #construction #civilconstruction #civilengineer #engenharia #engenhariacivil #engenheiro #engenheirocivil

Soil nailing is a method used to enhance soil stability in areas prone to landslides. The technique involves inserting steel bars into the soil and securing them to prevent potential slides. The process resembles hammering nails into the ground, with the steel bars acting as the nails. This technique provides support against slope failures and is known for its efficiency in construction. The process begins with drilling into the soil and inserting the steel bar at the specified depth indicated by a geotechnical engineer. The steel bar is then grouted into the soil, creating a structure similar to a gravity wall. To enhance the appearance of the project, a shot Crete layer is often applied as a protective cover for the steel bar, followed by additional finishes for an aesthetic appeal.

Diaphragm walls serve as both static structural elements and barriers against water infiltration. They can be utilized as retaining walls, barriers to prevent water seepage, or as part of a building's foundation. Typically constructed from concrete or reinforced concrete, diaphragm walls are highly resistant to water penetration. The excavation process involves the use of cable excavators equipped with #diaphragm_wall grabs or cutters, while a supporting fluid is utilized to facilitate the process.

#Soil_Collapse During Temporary Works Stage The video highlights a failure of anchored retaining walls, which can occur for several reasons. Common causes include weak anchors, flawed design, or errors in calculations , failure to estimate the temporary construction loads, like those from (crane foundations placed too close to the wall’s crest or underestimation of surcharge due to the use of heavier plant equipment, or even ignoring the fluctuations of water hydrostatic pressure. Generally, anchored soil/walls depend on tiebacks or soil nails to hold back soil pressure, groundwater forces, and additional loads. If the geotechnical analysis or design is insufficient, the wall may tilt, slide, or even collapse, leading to soil movement and potential damage to nearby structures. To prevent such failures, it’s crucial to conduct a detailed soil investigation, select the right materials, and accurately calculate all forces, including temporary loads, to ensure the wall’s stability and structural integrity.
