Method for measuring horizontal displacement of stratum through movable inclinometer and movable inclinometer

Abstract

The invention discloses a method for measuring horizontal displacement of a stratum through a movable inclinometer. The movable inclinometer is used for measuring total horizontal displacement and horizontal shift displacement, and the horizontal displacement of the stratum is calculated according to measurement numerical values. The invention further discloses the movable inclinometer. The movable inclinometer comprises a measurement reader, a GPS position finder, an inclinometer tube, an inclinometer cable, a cable support and a GPS position finder connecting sleeve. The measurement reader is located on one side of the inclinometer tube, the measurement reader and the inclinometer tube are independently arranged, the inclinometer cable is installed on the cable support, the GPS position finder connecting sleeve is fixed to the upper end of the inclinometer tube, one end of the inclinometer cable penetrates through the GPS position finder connecting sleeve and is connected with a movable probe in the inclinometer tube, at least one GPS position finder is arranged on the GPS position finder connecting sleeve, and the cable support is provided with Bluetooth used for transmitting signals received by the inclinometer cable to the measurement reader. By means of the method for measuring the horizontal displacement of the stratum through the movable inclinometer and the movable inclinometer, the drilling depth can be effectively reduced, economic cost can be reduced, the measurement data can better conform to field reality, and a more reliable base is provided for slope and foundation pit retaining and protection construction.

Description

technical field [0001] The invention relates to a movable inclinometer, in particular to a method for measuring stratum horizontal displacement by using the movable inclinometer and the movable inclinometer. Background technique [0002] At present, the inclinometer is an instrument used to measure the top angle and azimuth angle of engineering structures such as boreholes, foundation pits, foundations, walls and dam slopes. The inclinometer mainly includes a probe guide wheel and an inclinometer. The probe and the guide wheel of the measuring head are settled or lifted along the guide groove of the inclinometer guide. The acceleration sensor in the inclinometer guide head can sense the inclination angle of the guide tube at each depth, output a voltage signal, and pass it through a specific sine function. Converted to horizontal displacement. [0003] The existing inclinometer method requires that the horizontal displacement at the bottom of the inclinometer tube be zero w...
