Transmission Lines | Foundation

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.

Excellent work dear. Please keep it up. A great contribution.

[n.p.]

This is more useful than any power system book.

Is it advisable to discharge concrete from that height ? Why not use chutes? Pouring concrete and placing concrete are two different things .

[numbr]

A lot of hard work. Thanks for sharing.

[talatsonsurong]

Keep making these sorts of videos they're really useful

[LewisWangInfinite]

very useful and practical for me who is an english translator in the transmission line project.

10:40 casting is being done from a height that causes concrete segregation. It'd be better if a sloppy ramp was used.

More useful than any power system textbook.

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.

[rudythamrin]

Trial mix design it is good for make the quality of the foundation transmission

[kylemontaus]

Hello sir can i ask for a copy on your foundation plan?

[maksudalam]

Please make videos on pit marking in details

[satyampatel]

Prob setting ataa hein bhai @pritam singha roy

[samiyapandian]

Cover block missing under reinforcement after that backfill curring? 😜😜😜

[Saki]

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!
