BORED PILE HAVING INSERTION PIPE FOR SHOCK ABSORPTION

摘要

The present invention relates to a bored pile having an insertion pipe for shock absorption. The bored pile comprises: a concrete bored pile buried in a bored hole excavated on the ground by an excavation equipment; an insertion pipe coupled to the front end of the bored pile and inserted in the ground under a slime of the bored hole; and an elastic member installed to surround the circumference of the front end of the insertion pipe. The elastic member is installed in the front end of the insertion pipe to absorb impact caused by collision in spite of rocks existed in the ground under the slime of the bored hole when the bored pile vertically falls down to the lower part of the bored hole to be introduced; thereby preventing the insertion pipe and the concrete bored pile from being cracked.;COPYRIGHT KIPO 2016
