Technical Field
[0001] The utility model relates to the technical field of double-hole drilling machines, in particular to a double-hole drilling machine for reinforcing bar anchoring of a ballastless track of a high-speed railway. Background Art
[0002] Rebar anchoring refers to drilling holes in concrete, wall rock and other base materials, then injecting high-strength rebar anchoring glue, and then inserting steel bars or profiles. After the glue solidifies, the steel bars and the base material are bonded together. It is a commonly used construction engineering technology in the reinforcement industry. Therefore, drilling is a pre-step for rebar anchoring. Drilling refers to the operation of using a drill bit to make a hole in a solid material. Drilling machines are often used for drilling operations in engineering. Drilling machines include single-hole drilling machines, double-hole drilling machines, etc.

For this reason, we propose a double-hole drill for high-speed railway ballastless track rebar anchoring. Utility Model Content
