Looking at your video remonded me of a similar run we did for a client. We had to connect a new building to an existing one woth fiber optic for internet and other thing. It was the length as you but underground and the contractor we hired for laying the pipes didnt do the job right. So, we had 4 90° corner and no pulling spot on a 2200 foot run...We had to dig ourself 4 feet deep to disconnect, the non glued joint, at the corners and other part ti help pulling the cable. A 3 hours job turns out to be a full day...
