The invention relates to a sewer and a sewer dredging device. The sewer dredging device is characterized in that multiple sand settling wells are arranged along the sewer and are perpendicular to the sewer, the upper portion of each sand settling well is provided with a water inlet which is flush with or lower than the surrounding ground, the depth of each sand settling well is larger than the depth of the sewer, a sand settling cage is mounted in each sand settling well, the upper portion of each sand settling cage is provided with a fence, the upper edge of each sand settling cage is flush with the corresponding sand settling well or lower than a wellhead of the corresponding sand settling well, the lower portion of each sand settling cage is provided with a sand settling bucket, the sand settling buckets can not leak water or leak a small amount of water, the positions of the sand settling buckets are lower than the bottom face of the sewer, and the sand settling buckets are used for collecting silt and impurities in water; or, a sand settling bucket and a lifting ring are mounted on each sand settling cage; in the dredging process, the sand settling cages are lifted out manually or lifted out of the sand settling wells through a hoisting machine, and the silt in the sand settling buckets is discharged and carried away; or, sand settling pits are dug in the publicly known sewer, and a sand settling cage or a sand settling basket is mounted in each sand settling pit.
