Hello Nandini,
Unfortunately with a rank of 175k in jee main you are not eligible for admission in NIT and many other engineering colleges. It is also difficult to get igdtuw through jac counselling. I would suggest you to apply for colleges through your 12th board result. You  can also write various entrance test to get admission in the respective colleges. If none of them work the only option would be to get admission through management or vacany quota.
