HEATING APPARATUS FOR PAVEMENT CONSTRUCTION

摘要

To provide a heating apparatus for pavement construction that can efficiently heat and harden a pavement material when paving around a lid receiver frame of an underground installation; and which can cancel prohibition of traffic early without requiring a long time for hardening of a pavement material even in a winter or low temperature region.SOLUTION: A heating apparatus includes: a hot air generator 17; a hot air blower 20 that is removably attached on the front side of a hot air discharge pipe 18 of the hot air generator 17 and which is mounted on the upper surface of a lid 19 supported by a lid receiver frame 13; a cover body 21 that covers the lid 19, the lid receiver frame 13, and an excavation part 14 from above the hot air blower 20. The hot air supplied from the hot air generator 17 blows out radially from the hot air blower 20 toward the outer periphery of the cover 21 to heat pavement materials 15, 16.SELECTED DRAWING: Figure 4
