Watch in HD how Transmission Line Foundation are Constructed
Mostly we only recognize pylons and cables when we see a transmission line. This video contains details how the base for the massive structure is constructed.
Foundations of any structure plays on important role in safety and satisfactory performance of the structure as it transmits the loads from structure to earth. The towers legs are usually set in concrete which generally provides good protection to the steel. Without having a sound and safe foundation, structure cannot perform the functions for which it has been designed. Therefore, the importance of foundation needs not to be over emphasized.
The sizes of transmission line tower are increasing because of the present day high, extra high and ultra-high voltage transmission, resulting in heavier loads and as such requiring bigger and heavier foundations. Past records show that failures of tower foundations results in collapse of towers. These failures have usually been associated with certain deficiencies either in the design which or construction of foundation. From engineering point of view, task of design and selection of most suitable type of tower foundation is challenging because of the variety of soil conditions encountered in the transmission line and remoteness of construction sites. The foundations in various types of soil have to be designed to suit the soil conditions of particular type.

Hi Pritam, Could u please help in knowing how the foundation forces are calculated for Transmission Line Towers ?
Excellent work dear. Please keep it up. A great contribution.
This is more useful than any power system book.
PARABÉNS ÓTIMO TRABALHO. 🇧🇷
A lot of hard work. Thanks for sharing.
Thank you!
Wonderful Work
Keep making these sorts of videos they're really useful
excellent, very strong
thank you for this very nice video
Thanks you !!
Good job Pritam..
Bhut badhiya 👌
Excellent
谢谢
very useful and practical for me who is an english translator in the transmission line project.
Useful video
Thank you
Thank you sir
Nice video. keep up the good work
Is it advisable to discharge concrete from that height ? Why not use chutes? Pouring concrete and placing concrete are two different things .
awesome
Great

Please make videos on pit marking in details
Is concrete allowed to free fall from that height? Really surprising to me how engineer-in-charge accepted this. Easy but not right i think.

@M Daud 10:38 That looks like 8+ feet free fall to me, assuming the guy standing is at least 5 and half feet. I am a structural engineer and personally I wouldnt allow this in my projects under my supervision. I generally allow only 3 to 5 feet.

What would happen? Is there anything wrong if it is poured from that height? Just curious.

Prob setting ataa hein bhai @pritam singha roy
Cover block missing under reinforcement after that backfill curring? 😜😜😜
Development length too short.
why the fuck did I watch a robot tell me about stuff I dont care about? All i learned is that they have no harness for being elevated 10+feet in the air. No way they are surviving a fall from those heights!

What about earthing?
@PritamSingharoy

Depending on the soil resistivity, there are two types of earthing generally used in transmission line 1. Pipe Type Earthing 2. Counter-poise Earthing
Thank you
