A Texas construction worker plummeted 30 feet to his death down a shaft — with cops suspecting he may have been pushed while fighting wth a co-worker.

Married father of three Lorenzo Gonzalez, 46, died at a site in Sheldon, east of Houston, at 7:45 a.m. Monday, KRIV reported.

Gonzalez “was in a physical altercation with a co-worker when he fell 30 feet into an underground well station,” Harris County Sheriff Ed Gonzalez said, saying it was “possible [he] was pushed.”

However, no arrests have been made as the investigation continues, cops said.

Gonzalez was a “loving husband, devoted father and proud grandfather who meant the world to his family,” his loved ones said in a fundraiser.

“He was one of the hardest-working people we knew and always put his family first, working tirelessly to provide for them,” they said.
