Disclosed is cast-in-place pile top surface height measuring tool

The utility model relates to the technical field of measuring tools, and discloses a tool for measuring the height of the top surface of a cast-in-place pile, which comprises a measuring rod and a sieve piece, scale marks are marked on the measuring rod, and reading can be directly carried out through the scale marks; the lower end of the measuring rod is connected with the sieve piece, the upperend of the measuring rod extends in the direction away from the sieve piece, and the scale marks extend in the height direction of the measuring rod. A cavity is formed in the sieve piece; the upper part of the cavity is open; the sieve piece is provided with a peripheral side wall surrounding the periphery of the cavity; a plurality of gaps are formed in the peripheral side wall; when measurementis needed, the measuring tool is put down to the pile hole, slurry enters the cavity from the notch and then leaves the cavity from the upper opening, when the abutting part abuts against the top face of the cast-in-place pil
