What preventive method should we done if raining during boring of hole and during conreting of bored hole,and is there any effect if the bentonite mix with rain?
@desmondtan780728 күн бұрын
Can i ask when to do the test for bentonite slurry,is it before concreting?or after boring hole work done ?or before boring of the hole?

Thank you for watching our videos. In bored piling works, checking the bentonite slurry is a critical process to ensure the stability of the borehole and the quality of the final pile. Here are the key times when bentonite slurry should be checked: 1) Before pumping into the boredhole: Density: Ensure the density of the bentonite slurry meets the required specifications. Typically, the density should be around 1.03 to 1.10 g/cm³. Viscosity: Check the viscosity using a Marsh funnel. The viscosity should usually be between 28 to 40 seconds for a 1000 ml flow. pH Level: The pH should be between 8.5 and 10.5 to ensure the bentonite is active and will perform effectively. 2) During boring operation: Density and Viscosity: Regularly monitor the density and viscosity of the slurry during the drilling process to ensure consistency and to avoid sedimentation. Sand Content: Check the sand content regularly (typically it should be less than 4%) to prevent excessive wear on the drilling equipment and ensure the slurry can support the borehole walls. 3) Before Concrete Placement: Cleanliness: Ensure the bentonite slurry is clean and free from excessive sand and debris. This may involve desanding operations. Filtrate Loss: Check the filtrate loss of the slurry. This is important to ensure that the slurry does not dehydrate the soil excessively, which could destabilize the borehole walls. Density and Viscosity: Recheck the density and viscosity to ensure they are within the acceptable range for concreting. 4) After Concreting: Displacement Check: Ensure that the bentonite slurry is properly displaced by concrete during the pouring process. Monitor the return slurry for contamination and ensure it is properly disposed of or recycled. Consistent and careful monitoring of the bentonite slurry at these stages helps in maintaining the integrity of the borehole and ensures the successful installation of the pile. Feel free to ask questions! Thanks again. Kindly suggest our content to your friends and colleagues.

Should still be checking the offsets on the auger flights till at least the top of auger.start of true and sets it up for rest of the pile.

I dont understand the last part where they partially lift the casing for top up concrete. I thought its build up for pda but it collapse after they pulled out the whole casing. Great video though, thanks. But, somebody explain the last part pls. Thanks.
@ProudtobeaCivilEngineer3 ай бұрын
Thanks for watching the video. I'm happy to see that you asked a great question. Sometimes, the cut-off level is much deeper compared to near-surface. The sound concrete must be above the cut-off level for the bored piles. The pile cross-section is perfectly circular in drawings, but it's not in reality. This depends on the soil profiles as well as the verticality of the boring rig. Therefore, there are variations in the concrete quantities theoretically and actually. So, in order to ensure that the sound concrete is above the cut-off level, we usually top up the concrete at the end. That's why we lift the steel casing (ensuring that the required length is embedded below the ground) and pour the concrete into the casing. At the end, we remove the steel casing, as it is temporary. I hope this explanation answers your question.

We understand your thoughts. However, in piling, it's tough to stagger the lapping. It's all about practicality, not about practicality. We considered these practical issues in the design of piles.

MPI test purpose for what ?
@ProudtobeaCivilEngineer3 ай бұрын
Magnetic Particle Inspection (MPI), also known as Magnetic Particle Testing (MPT), is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials, such as iron, nickel, cobalt, and some of their alloys. Here's why it's particularly useful for inspecting welding: Detection of Surface and Subsurface Defects: MPI is effective in identifying both surface and just-below-the-surface discontinuities. In welding, this includes cracks, porosity, incomplete fusion, and other inconsistencies that might compromise the integrity of the weld. Immediate Results: MPI provides immediate visual results. The presence of any discontinuities is indicated by the accumulation of magnetic particles at the defect site, which can be seen directly. This immediacy aids in the quick assessment of the welding quality. Minimal Preparation Required: The surface preparation for MPI is relatively simple compared to other methods. The area needs to be clean, but extensive preparation is not necessary, making it a quick and efficient process for weld inspection. Sensitive to Small Defects: MPI is highly sensitive to small surface cracks and other discontinuities that might not be visible to the naked eye or could be missed by other NDT methods. Applicability to Complex Shapes: The method can be applied to complex geometries that are typical in welded structures. The magnetic field and the particles can conform to the shape of the object, making it versatile for inspecting welds in various configurations and positions. Cost-Effective: Compared to some other NDT methods, MPI is cost-effective, especially for the detection of surface and near-surface discontinuities. Its efficiency and speed also contribute to its cost-effectiveness. No Hazard to the Component: MPI is a non-destructive test that does not harm the material's structure or future usability, making it ideal for routine maintenance and inspection. In summary, Magnetic Particle Inspection is a crucial technique in welding to ensure the quality and integrity of welds, particularly in critical structures where strength and safety are paramount.

Actually it's a mock up test and has a much lower percentage of compliance with a real earthquake than the shaking table test. Because in a real earthquake, the movement of the earth exerts the force on the structure, and moving from the roof and connecting the structure to the ground is not suitable forsimulation construction.
