BEDROCK CUTTING METHOD BEFORE BREAKING BEDROCK USING DRILL

摘要

The present invention relates to a bedrock cutting gap forming method before breaking bedrock and, more specifically, relates to a bedrock cutting cap forming method using bedrock drilling equipment and to a continuously drilled hole forming method which enables continuous drilling by preventing a problem with poor constructability as a drilled end portion is constructed in a discontinuously drilled state even if a continuous drilling ground start unit is continuously drilled due to construction error and unevenness of the bedrock when connecting adjacent holes, and continuously drilling the same. To achieve this, in a process of connecting adjacent holes to the bedrock and forming continuously drilled holes, adjacent line location tubes and drilling axis (rod) location tubes of post construction drilling lines are connected to each other with a location connection plate, whereby the post construction drilling lines are always drilled along the drilling lines of adjacent line drilling even if there are construction errors and unevenness of the bedrock to form a bedrock cutting gap by forming continuously drilled holes.;COPYRIGHT KIPO 2017
