Connection and application of portable borehole inclinometer data acquisition instrument and inclinometer probe

 

WIN5/612 Multi function data acquisition instrument is a monitoring type multi-function digital display precision instrument designed for Geotechnical Engineering .

Main uses ： The borehole is inclined in both directions 、 Magnetic azimuth （ azimuth ）、 Measurement of displacement trend and other data . 
Application field ： Deep foundation pit excavation 、 Highway foundation 、 retaining wall 、 Underground Construction Engineering 、 Measurement and monitoring of internal displacement change of soil mass in dam and Landslide Engineering 、 Measurement of drilling quality .

One . Measurement principle
In all applications , Generally, inclinometer pipes should be installed in the boreholes of soil . The inclinometer tube has four notches （ chart 1.2）, To match the pulley of the inclinometer probe （ chart 1.1）, The probe is connected to the data meter by cable , By measuring the vertical inclination of the inclinometer , To detect the inclination caused by stratum movement 、 Pore forming quality 、. The inclinometer probe has two sets of small pulleys , Distance apart 0.5m, With 0.5m Measure the angle of each section in units , The horizontal offset of each segment can be calculated by the inclination angle of each segment , The relative horizontal offset of all survey sections can be integrated to obtain the relative reference point of any point in the borehole （ Hole bottom or hole top ） Horizontal displacement of .

Two 、 Connection and use of angle probe
1 Connection of angle probe
Here's the picture Shown , Assemble the split angle probe with a hexagonal wrench , Check whether the installation position is accurate , Whether the assembly is firm ; The supporting steel wire rope is installed to check whether the connection is tight .

2 Use of angle probe
Probe interface definition ：1： The power input is in normal use , The steel wire we are equipped with must be tied to the lifting ring above , Release probe .

Probe interface definition ：1： Power input 2：RS485A 3：RS485B 4： The power output is in normal use , The steel wire we are equipped with must be tied to the lifting ring above , Release probe .
