Equal species interspersed glass underground pipe repair method

The present invention discloses a method of repairing an underground path inserted species other glass pipe, both ends of the glass pipe trench excavation and repair segment cut glass steel; Breaking tractor through the glass tube, the glass tube through the axial direction thereof break; broken by pulling the reamer glass pipe, expanded to an inner diameter equal to or greater than the outer diameter of the new pipe; pulling the new tube glass pipe section after the repair into the counterbore. Species present inventors diameter interspersed method for repairing the glass tube has the following advantages: may be a long distance interspersed construction, using equal diameter, and so the pressure levels continuously reinforced plastic composite pipe of the original glass pipe lines and the like path through the replacement, repair pipes while ensuring pipeline technology parameters unchanged, does not affect the flow indicators and cost savings.
