Its a complete video explaining scratch from setting out to concreting of Bored cast in-situ Piling. For any person, who doesn't even know about piling also will understand clearly. Thanks for posting
Thank you for your valuable comments. Hope this video is much helpful for fresh graduates as well as for any person who doesn't know about bored piling works.
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.
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.
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?
Hi Ahmed Jameel, Referring to this video, The pile is Tension pile. So that the Rebar cage must be provided from the Toe of the pile. However, the Cut-Off_Level is 2m below the existing ground level. Due to the concrete pouring in a confined space, the rebar may have possibilities to move upwards slightly. So in order to control the slight upward movement, we are welding the rebar cage with casing.
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.

Bored piling works are related to soil profiles. Soft soils have a tendency to collapse during pile boring works. In order to overcome this issues, the stabilizing liquids are used. Bentonite slurry is one of the Stabilizing Liquids.
The vermiculate granules were poured into the pipe, to act as a separator in between the bentonite and the fresh concrete. This is to avoid the contamination of concrete with bentonite.

Love it from the Start to the End of this Video. I Learned many from it. Please accept my deepest Thanks.
Glad you liked it! Thank you so much for your compliments!!!
Thank you for sharing this video.
Thanks for watching!
Most detailed video about piling. Thanks 👍
Glad you liked it
Thank you so much , This video is very informative for me.
Thank you so much for your kind words
I appreciate your efforts ❤
Thank you so much 😀
Your the best
Thank you
So educative video
Very informative and educative. Thank you
Thank you for watching. Kindly recommend our channel if possible.
Very educative
Thank you
Thank you
very use full
Thank you
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.

Okay I get it now. Thank you for sharing 👍🏿
Tnx
Thanks for watching
How long does it take to finish the construction of one bored pile from setting out to concrete pouring?
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?
Thanks for the video. May I ask why does the reo cage welded to the casing? Is it because the bore is deeper than required?

@@ProudtobeaCivilEngineer thanks man
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?

What if the sand content or other viscosity too high?what can we done?air lifting will settle this issue?
If the cleaning bucket cant completely clean the bottom of the bore hole,the other method will be air lifting only?
Hi,any answer?

ayuuuuuun...
What is the purpose of the bentonite slurry?

Ooooo..... So you mean it coats the surface of the bored soil so that it will be stiffer?
@@jaynardmagbanua6595 yeah,
47:14 What is the reason ?
The vermiculate granules were poured into the pipe, to act as a separator in between the bentonite and the fresh concrete. This is to avoid the contamination of concrete with bentonite.
We are looking for Civil Engineers for our upcoming infrastructure projects.
