Disobey of court order

Recently on a survey number agricultural land a person who had permission from an ancestor to build a house on their land and stay for some years without any legal documents or money or anything. And after years stating adverse possession he started renovating or building house even tho told to stop. So a court order was issued for not listening to the owner of the land, who has legal documents in his name. The court sent direct injunction order to stop any activities on the land like construction. Even tho after receiving the order they still haven't stopped and continuously building and may finish the construction before the hearing date. So any suggestions how can I even stop them from constructing. For the notice I have taken pictures of the spot with gps map of each date like the date of petition submitted, the date of issue of order and continuously after that.
