A project which demonstrates that when the client and specialist contractor are prepared to work together as a team installation issues and setbacks can be overcome. This project found the ground to have a STP-N above 50 which required both parties agree to a change to the method of installation and introduce engineered designed tooling to allow the pilot head to be steered and the auger head to cut through the strong layered mudstone. This design change combined with changes to the installation procedure as increased the confidence for the use of guided auger boring in challenging ground conditions. Trenchless Solutions Limited have the capabilities due to the strong supply chain and installation equipment to be able to deliver projects utilising multiple pipe materials.

🚧 Project Update: Opal Drive Pump Station 🚧 The March Construction team, including Sujeet Meti, Jonas Taite, and Jeremia Christianto Tjandra Tjandra, are making great progress with the piling for the Opal Drive Pump Station in Papamoa, Tauranga. This project for Fulton Hogan involves constructing 4nr 800mm diameter and 9nr 1200mm diameter piles, reaching depths of 35m to 38m. Technical Challenges and Solutions: Ground Conditions: Located within 1km of Papamoa beach, the site consists mostly of loose and dense sand and water. Drilling deep holes in these conditions presents challenges such as sand and water running into the hole and the risk of collapse. Rotary Bored Piling Technique: To tackle these challenges, we adopted the rotary bored piling technique. Using our 100-tonne Liebherr LB28 hydraulic drill rig, we drill a pilot bore and screw down a temporary steel casing to maintain ground stability. We then auger out the pile using a rotary boring tool to the required depth. Managing Earth and Hydrostatic Pressures: Drilling piles involves forces exerted on the excavation walls due to earth and hydrostatic pressures, risking wall collapse. Counteracting these forces is crucial for excavation stability. Bentonite Support Fluid: To prevent wall collapse, we use Bentonite slurry support fluid. Our on-site Bentonite batching plant includes silos, tanks, a Desander unit, mixers, and pumps. The Bentonite slurry is pumped into the hole to maintain stability. Once the target depth is reached, we clean the base, insert a reinforcing cage, and use a tremie pipe to pour concrete, displacing the Bentonite slurry. Bentonite's high water-absorbent properties and cations (Na+) bring stability to the boring soil surface, forming a barrier coat and maintaining concrete quality in the pile foundation.

It pays to get a second opinion. A Client was looking at options to support its proposed design for a three leg jacket and topsides wellhead platform in a challenge to reduce time and installation (T&I) costs and, specifically, looking at traditional driven pile foundation verses suction can piled foundations. ICON verified the input data, such as geological conditions, water depth, type of offshore platform, meteorological conditions, topside and jacket structure, construction equipment and lifting crane. We then proposed a varied substructure concept design including the suction pile foundation. This also came with strategies for reducing installation risks. Crucially, the study showed not all proposed locations had soils that were technically feasible for suction can foundations. Additionally, if a two-piece substructure was used, the Client could employ cost saving, innovative jackup rig transportation and installation techniques. Interestingly, ICON found its suction can foundation design concept could be extended to the Client’s range of larger jacket designs. ICON’s experience in designing and installing suction piled foundations allowed the Client to add value to its existing WHP designs with a credible and robust engineering solution in a technically suitable location.

Bored piles, also known as drilled shafts, are a type of deep foundation element used to transfer loads from a structure to a deeper soil layer or rock. They are constructed by drilling a hole into the ground and filling it with concrete, often with a reinforcing cage. Characteristics: - Large diameter (typically 300mm to 3000mm) - Depth can range from 5m to 100m or more - Can be constructed in a variety of soil and rock conditions - Can be used for both compression and tension loads Advantages: - High load-carrying capacity - Reduced settlement - Improved stability - Can be used in challenging soil conditions - Low noise and vibration during construction Construction process: 1. Site preparation 2. Drilling the hole using a rotary drilling machine 3. Installing the reinforcing cage 4. Pouring concrete into the hole 5. Curing the concrete Common applications: - High-rise buildings - Large commercial and industrial buildings - Bridges - Dams - Offshore structures - Foundation repair and retrofitting Bored piles are a popular choice for deep foundations due to their versatility, high load-carrying capacity, and ability to be constructed in a variety of soil and rock conditions.

Choosing the right size generator for a construction site is crucial to ensure smooth operations and avoid downtime. Here, we'll explore the key considerations and steps to determine the optimal generator size for your construction needs.

D Wall Anchor Drilling Process: Anchor are what ensures that these diaphragm walls are sturdy enough to keep these structures intact is Anchoring. All diaphragm wall construction companies will unanimously agree that Anchoring is one of the most important aspects of diaphragm wall construction. Here’s how we drill into… A drill rig is used to drill boreholes of 150 to 180 mm, at 15 to 30 degrees and the anchor tendon is put into the hole in the center. Upon completion of boring, the borehole is cleaned through compressed air. A low relaxation prestressed steel (LRPC) strand as per approved design is inserted into the bore and the anchor is grouted. The anchor is usually 15 meters, of which an approximate 10 meters are considered to be bonded length, and the remaining is called Unbonded or free length. An Emery paper is used to clean the steel tendons first. The Araldite and hardener is applied on to it, followed by quad sand before the tendons dry up, so that the sand sticks to it. The free length area is then covered with a sheath. HDPE pipe or duct is added inside the sleeve before Grouting. The anchor head is then pre-tensioned by jacking after 5-7 days, and the anchor heads are set in place. The anchor is later distressed after the slab casting is done.

"Building Strong Foundations: Secant Pile Walls in Construction" Drilling with casing for secant pile walls is a specialized construction method used to create strong and interconnected reinforced concrete piles. This technique is crucial for building robust retaining walls and foundations, especially in challenging soil conditions. It begins with placing a steel casing into the ground, matching the diameter of the secant piles to stabilize the borehole. Once secured, drilling commences, facilitated by the casing which prevents the borehole from collapsing and maintains its integrity as the drill progresses through different soil layers. After drilling, the casing may remain in place or be partially removed while concrete is poured into the hole. This process forms the secant piles, which interlock with each other to create a continuous and durable wall structure. Secant piles provide excellent structural support, mitigate soil movement, and are ideal for stabilizing excavations and preventing groundwater ingress. This method ensures the reliability and longevity of construction projects, particularly in areas where conventional methods may not suffice. video rights : Respective owners DM for removal /credits #secantpile #piling #engineering #civilengineering #construction #civilconstruction #engenharia #engenharicivil #geotechnical #technology
