Tube well filter tube

The utility model relates to the technical field of underground drainage construction, and discloses a tube well filter tube which comprises a metal tube body, a plurality of through holes are formed in the tube wall of the metal tube body, and a filter screen is wrapped on the outer side of the metal tube body. The cylindrical steel reel pipe is used as the metal pipe body, so that the time for prefabricating the concrete well pipe can be saved, transportation and processing are facilitated, compared with the concrete well pipe and the metal pipe body, the wall thickness can be reduced while the strength is guaranteed, and under the same drilling size, the internal space of the metal pipe body is larger, and the drainage efficiency is higher; the two layers of 100-mesh steel wire meshes are adopted as the filter screens to wrap the outer side of the metal pipe body, so that the filter effect is guaranteed, and meanwhile, the filter screens are prevented from being too thick to block the through holes. 本实用新型涉
