MEASUREMENT AND ITS USING MEASUREMENT METHOD FOR DIRECTION AND ANGLE OF INCLINATION OF GEOLOGICAL STRATUM IN EXPLORATORY HOLE

摘要

An apparatus and method capable of precisely measuring a juhyang and inlined angle of a jeoly which are distributed at a base rock layer in an underground are disclosed. In the apparatus, rods(4) are inserted into a drilling hole(B) and connected to one another by a connecting pin(2). A rubbed copy means(6) is mounted at a final end of the rods(4). A pipe(14) is arranged at a center portion of rubbed copy means(6). A hole(12) is formed at a peripheral surface of the pipe(14). An expanding member(16) and an impression packer(18) are mounted at a peripheral portion of the pipe(14) in the form of double pipes. Upper and lower sides of the expanding member(16) are intercepted by a locking member(20).
