Layfield Geosynthetics’ Post

It's been a heck of a week for me. It's not easy when I’m on site 10 hours+, been working on Saturdays and have assignments due. This week, I worked tirelessly trying to get my assignment in on time, but I somehow did it! 😓 I wrote all about substructures and superstructures, #site investigations, different types of foundations (raft, pile and suspended #concrete), load bearing capacity and soil, carbon fibre, dewatering methods and more. I also went to the tank and learned all about penetrant testing, visual testing and the non destructive ultrasonic machine that the Non Destructive Testing #ndt guys use. It’s been one of those weeks but I got through it all and I’m proud of myself. #structuralengineering #civilengineering #builtenvironment #womeninconstruction #engineeringcareer #constructioncareers #oilandgas #constructionindustry #structuralsteel #concrete #infrastructure #infrastructurebuilding #insitu

📍 MechTest Geomembrane Liner Testing 🌍 Geomembrane liners are used in various applications, including environmental containment systems, water management, and construction projects. 🌍 The integrity of geomembrane liner welds is critical to prevent leaks, maintain environmental protection, and ensure structural stability. Several tests and quality control measures are employed to assess the quality of geomembrane liner welds. 📍 Destructive Testing Destructive testing involves removing samples of geomembrane liner welds for laboratory analysis. Common destructive tests include: 📍 Tensile Test: Like ASTM D638 for plastics, a tensile test can assess the weld's tensile strength and elongation properties. 📍 Contact our expert engineers now! #MechTest #NATAAccredited #MaterialTesting #ProductTesting #ChemicalAnalysis #CorrosionTesting #MetalAnalysis #Compliance #PolymerPropertiesTesting #StateoftheArt #BrisbaneLaboratory  #Safety #MechanicalTesting #Brisbane #Queensland #Engineering #MaterialsScience

You cannot manage what you do not measure Blasting team working together to ensure proper QAQC of the blasting block. In this picture the team is : 1) Measuring the final charged gas height to record the final stemming depth (used for analysis and improvement on future blocks) 2) Using a Varistem stemming device to ensure that all the stemming heights for every blast hole is the same, ensuring better adherence to your planned blast design. Having the data and, actually looking at it, can help you to understand why/what is going on, on your block. ERG Industrial

what is the biggest challenge you may face during construction of underground pipeline? for me it was during Pre-comm phase,,,how to find deffected pipe without using calliper pig also how to find leakage on welds without using leak detection pig

Crosshole Sonic Logging (CSL) for Drilled Shaft Integrity The structural integrity of drilled shaft foundations often involves uncertainties due to subsurface conditions and construction variables. Even with stringent quality controls in place, issues like voids, honeycombing, or inadequate concrete consolidation can occur, compromising structural performance. Crosshole Sonic Logging (CSL) addresses these concerns by providing a non-destructive method to evaluate drilled foundation integrity. Ultrasonic transmitter and receiver probes are inserted into pre-installed access tubes within the concrete. As the probes are simultaneously raised, ultrasonic pulses traverse the concrete between them. By measuring the travel time and amplitude of these pulses, we can detect anomalies that are otherwise unknown. At MC Squared Engineers, we employ advanced analysis techniques to obtain reliable assessments of shaft integrity. Through detailed signal processing and interpretation of shaft installation records, we accurately identify any potential defects, providing contractors with critical information to make well-informed decisions and implement corrective measures that are necessary to enhance structural performance. #Engineering #DataAnalysis

Subsurface injection of remediation substrates is commonly performed with a direct push rig driving vertical injection points. While this method is common, it doesn’t provide a solution for the injection of substrate under obstructions such as roadways or building foundations. Following months of collaboration between Ellingson-DTD and Innovative Environmental Technologies, Inc. (IET), we have designed tooling and methodology for un-screened, direct injection of substrates utilizing horizontal directional drilling methods. Ellingson-DTD/IET crews drilled and injected substrate into 24 horizontal directionally drilled borings under active multi-lane roadways. The total footage was about 3,855’ for an average length of 161’ per bore. Once a boring was completed, the guidance tooling was removed and the direction injection tooling inserted. The injection tooling seals against the horizontal bore hole walls and substrate was injected under pressure into the injection zones. Approximately 1,000,000 pounds of modified permanganate solution for the purpose of mass removal and flux reduction were placed in the subsurface. hashtag #horizontalenvironmental #contamination #groundwater

Cross hole sonic logging (CSL) is a type of #nondestructive testing method used to determine the integrity and quality of concrete within drilled shafts, #piles or other deep foundations. Two or more sonic tubes are installed by being tied to the reinforcement prior to casting of concrete in a bored pile. The cross hole probes / trans-receivers emit ultrasonic pulses and the other probes receive the same simultaneously while the access tubes are filled with water. A device called the CHAMP-Q is being used to provide this service. Cross Hole Analyzer-TM (CHAMP-Q) Consists of the following equipment:  -> A computer-based CSL data acquisition system for display of signals during data acquisition, with a minimum 12-bit A/D converter with a sampling frequency of at least 500,000 Hz and recording of all pulse signals for full analysis and individual inspection. -> Ultrasonic transmitter and receiver probes capable of producing records at a minimum frequency of 40,000 Hz with good signal amplitude and energy through good quality concrete. The probes shall be less than 1.1 inches in diameter and shall freely descend through the full depth of properly installed access tubes in the bored piles. -> Two depth sensors to independently determine transmitter and receiver probe depth. -> Triggering of the recording system time base with the transmitted ultrasonic pulse The limitations of the test are, - Proper installation of the access tubes is essential for effective testing and interpretation. The method does not give the exact type of defect (for example, inclusion, honeycombing, lack of cement particles, etc.) but rather only than a defect exists.  - The method is limited primarily to testing the concrete between the access tubes and thus gives little information about the concrete outside the reinforcement cage to which the access tubes are attached to the inside of the reinforcement cage.
