Abstract

The invention provides a tensioning mechanism with pre-tension torque adjustable, an inclinometer device and a usage method thereof, belongs to the field of building construction control, and aims at solving the problem that the inclinometer device cannot adapt to different inclinometer pipe diameters. The inclinometer device comprises at least one probe, a steel wire cable and a measuring and reading instrument, and each probe comprises an upper instrument cavity body, a lower cavity body, a middle connection rod and two sets of guide wheel tensioning mechanisms; the tensioning mechanism with the pre-tension torque adjustable comprises a piston, an inner sleeve, an outer sleeve, a spring and an adjustment cap; the piston comprises a cylindrical table and a cylindrical pin, the inner sleeve is provided with linear guide grooves, the outer sleeve is provided with symmetrical spiral guide grooves, the cylindrical pin penetrates through the linear guide grooves firstly and then the symmetrical spiral guide grooves, and the spring is arranged in the inner sleeve and located between the cylindrical table and the adjustment cap. Through the tensioning mechanism with the pre-tension torque adjustable, the friction force between guide wheels of the inclinometer device and a guide groove of an inclinometer pipe is always within an appropriate range, the adaptability of the inclinometer device is improved, and the construction monitor cost is effectively saved.

Description

technical field [0001] The invention relates to the field of building construction control, in particular to an inclinometer with an adjustable pre-tightening torque tensioning mechanism and a method for using the same. Background technique [0002] With the rapid development of the city, the number and scale of foundation pits are increasing year by year, especially the large and deep foundation pits have grown geometrically in recent years. Therefore, the safety and stability of deep foundation pits have become the first priority in the construction process. One of the important factors to consider. Because the foundation pit construction technology is to dig out the rock and soil in a certain local area, which destroys the balance of the original rock and soil structure, the rock mass around the foundation pit will affect the structural wall of the foundation pit enclosure wall (referred to as the foundation pit enclosure wall) , such as the underground diaphragm wall) a...
