शिक्षा के इस मुद्दे को उठाने के लिए news 18 और विवेक जी का बहुत-बहुत धन्यवाद. बिहार के शिक्षा व्यवस्था माध्यमिक स्कूल से लेकर कॉलेज, यूनिवर्सिटी तक कहीं भी अच्छी नहीं हैं। जब सरकारी स्कूल सरकार दी ही है तो प्राइवेट की जरूरत क्यों है क्योंकि सरकारी स्कूलों में पढ़ाई नहीं होती मैं अपना नामांकन सरकारी और प्राइवेट दोनों स्कूलों में करवा रखा था लेकिन सरकारी स्कूल में सिर्फ पोशाक के पैसों क लिए जब कभी जाता था और अभी कॉलेज में हूं लेकिन कॉलेज में टीचर कहते हैं पढ़ाने के लिए लेकिन वहां टाइम पर सिलेबस खत्म नहीं होती और सरकारी छुट्टी बहुत होती इसलिए मैं तीनो साल प्राइवेट कोचिंग ही किया
I have a question about this... after completing stressing ,while releasing, master wedges sometimes struck in strands. I saw one worker pulling the master wedges from inside the jack , how could you release the wedges if struck... why dont use the back block ??
Ghulam Murtaza once the ram is retracting it releases the pressure off of the master wedges. If a wedge on the steel head slips or breaks the master wedge will catch the strand then it will be impossible to pull the master wedge off by hand. Instead of destressing though... you cut the strand that is stuck 3 inches long behind the ram/master wedge that’s stuck. Then get a torch and burn the middle wire of the strand (the strand consist of 7 intertwined steel cables one being in the middle the other six around it) so burn the middle one and it will cause the strand to collapse and blow out the back end...( it usually just gets caught with all of the other stressed strand) once you do that. The master wedge that was once stuck will be worthless lolbut the ram will be able to come off of the cables. Tada.

जब सरकारी स्कूल सरकार दी ही है तो प्राइवेट की जरूरत क्यों है क्योंकि सरकारी स्कूलों में पढ़ाई नहीं होती
मैं अपना नामांकन सरकारी और प्राइवेट दोनों स्कूलों में करवा रखा था लेकिन सरकारी स्कूल में सिर्फ पोशाक के पैसों क लिए जब कभी जाता था
और अभी कॉलेज में हूं लेकिन कॉलेज में टीचर कहते हैं पढ़ाने के लिए लेकिन वहां टाइम पर सिलेबस खत्म नहीं होती और सरकारी छुट्टी बहुत होती इसलिए मैं तीनो साल प्राइवेट कोचिंग ही किया

Destress the cable

Y clean with lime water
I think this is at new Mumbai Metro? Post tensioning of Y Blocks(viaduct).
what process is used for removal of entrapped air n water...?
Air you don’t worry to much about because it’ll later get grouted.. but water can be blown out of the grouting holes via air pressure testing
@@anthonyrenemolina grouting means filling slurry into segments rht after allignment done post tensioning
Thank u for giving total detail process

अगर सरकार की दी गई व्यवस्था में अच्छी पढ़ाई होती तो लोग प्राइवेट स्कूल और कोचिंग में अलग से क्यों पैसा खर्च करते
