PROBLEM TO BE SOLVED: To reduce temperature of exhaust gas discharged from a drainage tool provided in an exhaust gas treatment device.SOLUTION: In a hydraulic shovel 1, an exhaust gas treatment device 17 is provided for purifying exhaust gas discharged from an engine 7 and for absorbing sound, and on a lower vertical side in an outlet port 22c side of the exhaust gas treatment device 17, a drainage tool 28 is provided for discharging moisture accumulated in the exhaust gas treatment device 17 to the outside of a vehicle body. The drainage tool 28 includes an upper cylindrical body 29 having a bottomed cylindrical shape, and a lower cylindrical body 30 fixed to the lower side of the upper cylindrical body 29. The upper cylindrical body 29 has, on an inner peripheral surface 29D thereof, a partition member 31 for partitioning the upper cylindrical body 29 into an upper side chamber S1 and a lower side chamber S2. The partition member 31 has two communication holes 32 at a position vertically different from an opening 29C provided at a bottom part 29B of a cylindrical part 29A of the upper cylindrical body 29, allowing the upper side chamber S1 and the lower side chamber S2 to communicate with each other. |
