Inclination measuring device and measuring method of sunk well

The invention provides an inclination measuring device of a sunk well, which is a measuring system for fast monitoring of inclination of the sunk well during the construction period, and mainly consists of a rectangular annular communicating water pipe, a square vertical pipe, a liquid medium and a high-precision water level gauge mounted in the vertical pipe. The inclination measuring device is mounted and embedded in concrete of a well wall (periphery) of the sunk well, thereby determining the inclination of a well body before, after and during the sinking construction process of the sunk well by monitoring the relative liquid level and the change of liquid in the square vertical pipe of the sunk well and providing necessary actual measurement data for controlling and guiding the sinking construction of the sunk well for studying the design of the sunk well and the well sinking method construction. The inclination fast measurement of the sunk well adopts the automatic continuous detection way and can automa
