Construction method for treating separated double-hole tunnel water inrush

The invention discloses a construction method for treating separated double-hole tunnel water inrush and adopting the following technical schemes. The construction method comprises the following stepsthat S1, the position of a water inrush breach in a follow-up hole is determined, and the positions of steel pipe walls constructed in front of and behind the water inrush breach are determined according to the construction requirements; and S2, entering the follow-up hole from a first hole through connected holes is conducted, the steel pipe walls are vertically arranged on the set positions infront of and behind the water inrush breach, the upper parts of the steel pipe walls are closely attached to the top wall of the follow-up hole, the left ends and the right ends of the steel pipe walls are closely attached to the left side wall and the right side wall of the follow-up hole, a water inrush body is divided into an independent front water inrush body, an independent middle water inrush body and an independent
