Urban waterlog test pipe dredging device

The utility model relates to an urban waterlog test pipe dredging device and belongs to the technical field of urban waterlog monitoring. According to the technical scheme, the lower end of the upper portion of a test pipe is in butt joint with the upper end of the lower portion of the test pipe, so that the integrated test pipe is formed. The butt joint position (6) is wrapped inside a connection pipe (3), and the upper portion (1) of the test pipe and the lower portion (2) of the test pipe are equal in outer diameter. The inner diameter of the connection pipe is slightly larger than the outer diameter of the test pipe. A connection pipe locking device (4) is arranged on the outer side of the connection pipe and locks the connection pipe. The upper portion of the test pipe, the lower portion of the test pipe and the connection pipe form a detachable integrated structure by being locked through the connection pipe locking device. When sediments on the lower portion of the test pipe need to be cleaned away, the connection pipe locking device is opened, and cleaning is conducted by taking down the lower portion of the test pipe. The urban waterlog test pipe dredging device has the advantages that the structure is simple, a road water-logging test pipe can be simply cleaned, and therefore the reliability of a waterlog monitoring device is improved.
