The utility model discloses an anti-blocking device for a drainage pipe for civil engineering construction, relates to the technical field of civil engineering construction, and provides the following scheme aiming at the problems that a pipeline needs to be taken down and is troublesome to clean in the prior art, and the length of a cleaning device is fixed and a longer pipeline cannot be cleaned: the anti-blocking device comprises a pipe, one end of the pipe extends inwards to be provided with an extending mechanism, one end of the extending mechanism is provided with an air blowing mechanism, the air blowing mechanism penetrates through the extending mechanism and extends into the pipe, the outer wall of the extending mechanism is slidably connected with a clamping mechanism, and the clamping mechanism is of a threaded locking type connecting structure. The pipe cleaning device is novel in structure, impurities on the inner wall of a pipe can be pushed away through the device, the impurities can be blown a
