It is obligatory to pray your prayers in the set time. It is recommended to pray these prayers in a mosque. If you are forced to fold your arms, then you should be praying elsewhere. If there is nowhere else to pray then you should pray when you get home as long as it is still in the set time. If waiting till you get home means that you will be praying Qadha then you should find a new job.
I stay in gulf country where our mosques are hardly few and the place where I work is far from our mosque. Can I pray my zohar and Asr at any other mosque with my hands folded (in taqiyah) and will it be counted as a valid prayer and performed at avale waqt or I should have to repeat my prayers once I am back home as per our fiqh (by keeping hands aside and with turbah)?

Yes, you can, but there is no need to fold the hands, as not all other sects fold their hands.
