General description

INCLINOMETER CASING

Instruments, Software and Systems01

The inclinometer casing is installed, for example, in boreho-les, piles, fills, retaining or diaphragm walls. A total of four keyways (grooves) are arranged at an angle of 90° to each other and serve to accommodate the wheels of inclinometer probes. Generally, inclinometer probes are used to monitor displacements perpendicular (lateral) to the casing axis.

The installation can be vertical, horizontal or inclined. Hori-zontal displacements for vertical installation and settlement curves for horizontal installation can be determined. The indi-vidual casing tubes are connected to form a continuous pipe string by means of the integrated couplings.

INCLINOMETER CASING

Principle of operation

Specifications

01

The integrated couplings of the casing tubes are pushed over each other and secured with glue and rivets. A fitting button ensures an exact alignment of the grooves for the entire pipe string. The inclinometer casing is installed with a pair of grooves in the reference direction. For vertical boreholes, the reference direction should be corresponding to the expected movement. For horizontal and inclined holes, one pair of grooves must be aligned vertically. The annular space between the guide tube and the borehole wall must complete be backfilled.The lateral displacements of the casing are recorded using mobile inclinometer probes or stationary inclinometer measuring chains (IPIs = In Place Inclinometer).In order to record axial movements along the casing (settlements during vertical installation), a combination with Increx measuring rings, metallic sensing rings or magnetic rings for the use of probe extensometers is possible. For the geodetic monitoring of 3D displacements of the inclinometer head, an optical target can be mounted on the top cap.
