Hole pile underwater concrete pouring positioning device

The utility model particularly relates to a hole pile underwater concrete pouring positioning device. An in-place prompt sieve is loated at a designed pouring elevation position of underwater concrete in a hole pile, a signal marker is arranged on the in-place prompt sieve, and a plurality of concrete detection boxes are detachably fixed on a steel reinforcement cage simultaneously and are located at the designed pouring elevation position of the underwater concrete. When the underwater concrete is poured to a designed elevation, the in-place prompt sieve can be jacked up, the signal marker is led to the designated position to indicate that the concrete is roughly poured in place, and then samples are taken through the concrete detection boxes so as to detect whether the underwater concrete is completely poured to the designed pouring elevation. The hole pile underwater concrete pouring positioning device has the advantages that the hole pile underwater concrete pouring positioning device is simple in structu
