Description

Hot-wire induction drainage method in tunnels and underpasses

The present invention relates to a heat-guided drainage method in tunnels and underground roadways that prevents water flowing out from expansion joints, cracks, and induced drainage of tunnels and underground roadways to freeze at sub-zero temperatures. The present invention relates to a heat-guided drainage method in tunnels and underground roadways to prevent freezing of spilled water and to safely move to drain pipes and to secure the running of road structures and vehicles.

In general, tunnels and underground roadways have a form in which a vehicle travels inside a structure whose front section is formed in a □ shape or a ∩ shape, and a expansion joint, a crack part, an induced drainage part, etc., due to the performance deterioration and structural failure of the structure. Leakage section is installed to prevent the freezing by installing induction drainage means and to act as an induction drainage.

In the tunnels and underground roads, when the front section is constructed in the shape of □ or ∩, water flows out of the aging and expansion joints, cracks, induction drainage, etc., and the water flows and the temperature drops to below zero. As the ice is frozen, tunnels and underground cars also form ice walls on the walls, which reduces the traffic area, threatens the safety of vehicles and pedestrians moving inside due to falling ice, and frequently causes safety accidents. In order to manage the situation, the person in charge had to continuously remove the ice, and accordingly, there was a problem in that a continuous maintenance cost was incurred.
