Title:
CONCRETE SAMPLING APPARATUS AND METHOD
Document Type and Number:
Japanese Patent JP2018012255
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete sampling apparatus capable of sequentially sampling concrete for examination to confirm progress of deterioration of a concrete roof.SOLUTION: A concrete sampling apparatus 2 comprises a support body 3 detachably arranged on a concrete roof 1 so as to extend from the upper side 101 to the lower side 102 of the concrete roof 1 through a through hole 1a of the concrete roof 1, a core bit 4a, a driving device 5, and a feeding device 6. The core bit 4a is for sampling a concrete core 1x by drilling a back surface 1b of the concrete roof 1 and is supported by the support body 3 on the lower side 102 of the concrete roof 1. The driving device 5 is operated from the upper side 102 of the concrete roof 1 to impart a rotational force to the core bit 4a. The feed device 6 is operated from the upper side 101 of the concrete roof 1 to move the core bit 4a forward and backward with respect to the concrete roof 1.SELECTED DRAWING: Figure 2
