Construction method for pre-drilling mechanical excavation for stone
The invention discloses a construction method for pre-drilling mechanical excavation for stone, belongs to the field of mechanical engineering, and is used for solving the problems that the construction cost of static blasting is high, the construction speed is slow, and the urban stone excavation efficiency is low. The construction method comprises a construction preparation stage, an excavation route planning stage, a plum blossom pre-drilling stage, a layout guiding gray line stage and a scarifier construction stage. The method adopts a down-the-hole drill for pre-drilling, and pre-drilled holes comprise stress holes and presplit holes. The stress holes are utilized to provide acting points for a scarifier, and meanwhile the presplit holes are distributed in a plum blossom shape and utilized to destroy the rock mass integrity. The construction method has the advantages of being high construction speed, low in construction cost and low in construction noises.
