Wastewater collecting device for core drilling machine

The utility model relates to the field of road surface sampling, in particular to a waste water collecting device for a core drilling machine, which comprises a cylindrical structural member, a sealing member is arranged at the bottom of the cylindrical structural member and used for abutting against a road surface, and a pile core operation space is formed in the cylindrical structural member. The cylindrical structural member is provided with a drainage pipeline communicated with the pile core operation space; by arranging the cylindrical structural member, sewage generated by the core drilling machine is collected and discharged, so that the pollution area caused in the sampling process is controllable, the road surface cleaning time is shortened, the amount of water used for cleaning the road surface is reduced, the water stability damage of an asphalt surface layer is reduced, the working efficiency is improved, and the road surface cleaning cost is saved. 本实用新型涉及路面取样领域，特别涉及一种用于钻芯机的废水收集装置，包括筒状结构件，所述筒状结构件
