INSTRUMENT FOR MEASURING FLOW DIRECTION AND FLOW VELOCITY OF GROUND WATER

摘要

PPROBLEM TO BE SOLVED: To provide a ground water flow measuring instrument allowing measurement without being installed to align an axial line of a boring hole with an axial line of a ground water flow direction flow velocity meter, as to the ground water flow direction flow velocity meter of a type of installing, in the boring hole, a "cord or rod" or the like serving as a mark capable of obtaining a motion by a flow direction and a flow velocity of ground water so as to obtain the flow direction and the flow velocity of the ground water indicating a complicated behavior in the boring hole. PSOLUTION: This instrument is the ground water flow direction flow velocity measuring instrument provided with the boring hole, the flow direction flow velocity meter for the ground water, and an attaching member, and not required to be installed to align the axial line of the boring hole with the axial line of the ground water flow direction flow velocity meter, and the flow direction flow velocity meter for the ground water can measure the accurate flow direction and flow velocity of the ground water, without being installed to align the axial line of the flow direction flow velocity meter for the ground water on the axial line of the boring hole.
