Pile position positioning steel plate for down-the-hole machine

The utility model relates to the technical field of building construction equipment, in particular to a pile position positioning steel plate for a down-the-hole machine, which comprises a steel plate, the steel plate is divided into a splice plate I and a splice plate II which are symmetrically arranged along a center line, a circular limiting hole is formed in the middle of the steel plate, positioning holes are formed in four corners of the steel plate, and sand filling holes are formed in two sides of the limiting hole in the steel plate. The utility model has the beneficial effects that by arranging the positioning steel plate, the down-the-hole position of the down-the-hole machine can be limited, the down-the-hole precision can be improved, the pile insertion position of a subsequent precast pile can be limited, the insertion precision can be improved, the construction efficiency of the precast pile can be effectively improved, and the installation stability of the precast pile can be improved; the per
