The central drainage ditch and the upper cover-opening type side drainage ditch are both arranged on an inner ring of the secondary support of the tunnel, and the flexible electric heater is coated on the outer walls of the central drainage ditch and the two side drainage ditches.
The anti-icing heat preservation including heat preservation coating and anti-icing coating, the heat preservation coating coat on the inner wall of drainage pipe, central drainage ditch and on uncap formula side drainage ditch inner wall all around, anti-icing coating coat on the heat preservation coating inner wall that corresponds.
A plurality of flexible electric heaters are uniformly distributed on the outer walls of the drainage guide pipe, the central drainage ditch and the two side drainage ditches along the extension direction of the axis of the drainage guide pipe, each flexible electric heater comprises a flexible electric heating sheet and a temperature sensing sensor, and the temperature sensing sensor is connected with an electric control assembly corresponding to the flexible electric heating sheet.
The utility model has the advantages that:
(1) the utility model discloses add and open the formula side escape canal on, be favorable to the tunnel water-logging to discharge rapidly, reduce the icing volume, can artifically uncap simultaneously and remove ice, prevent strictly because of freezing the problem that blocks up the drainage, cause the tunnel damage
(2) The utility model discloses on the outer wall of drainage pipe, all set up flexible electric heater on the periphery of central drainage ditch and both sides escape canal, accomplish the real-time supervision temperature, guarantee that temperature is above freezing point in ditch (pipe), prevent that ditch (pipe) interior water from freezing the jam, causing the tunnel infiltration to freeze and destroying.
(3) The utility model discloses on the inner wall of drainage pipe, central drainage ditch and go up and uncap formula side drainage ditch all set up the heat preservation coating on inner wall all around, prevent that the heat from scattering and disappearing, the anti-icing coating of coating on the heat preservation coating prevents to freeze in escape canal, the drainage pipe, avoids reducing discharge.
