Embodiment 1

[0033] Put the center of gravity measuring instrument on the structural surface flat on the structural surface, and when the instrument is stable, the position of the south needle 7 and the position of the central partition 1

[0034] Such as Figure 4 As shown, the relative angle scale pointed by the south needle 7 in the figure is 80 degrees, that is, the true inclination azimuth is 80 degrees.

[0035] After the instrument is stabilized, the relative position relationship between the spherical shell and the middle plane 4 is as follows: Figure 5 As shown, at this time, the middle plane 4 corresponds to the scale line with an inclination angle of 20 degrees, so the true inclination angle of the structural surface is 20 degrees.

Embodiment 2

[0037] Put the center of gravity measuring instrument on the structural surface flat on the structural surface, and when the instrument is stable, the position of the south needle 7 and the position of the central partition 1

[0038] Such as Figure 6 As shown, the relative angle scale pointed by the south needle 7 in the figure is 210 degrees, that is, the true inclination azimuth is 210 degrees.

[0039] After the instrument is stabilized, the relative position relationship between the spherical shell and the middle plane 4 is as follows: Figure 7 As shown, at this time, the middle plane 4 corresponds to the scale line of the inclination angle of 40 degrees, so the true inclination angle of the structural surface is 40 degrees.

[0040] Such as figure 1 and figure 2 As shown, the center of gravity type structural surface occurrence measuring instrument of the present application includes a frame 3, a central partition 1, and a spherical compass 2. The frame 3 includes ...

Abstract

The invention relates to a structural surface occurrence measuring method and a gravity center type structural surface occurrence measuring instrument, and in particular relates to a structural surface occurrence measuring method and a gravity center type structural surface occurrence measuring instrument which are applied to the field of civil engineering. The invention provides a gravity center type structural surface occurrence measuring instrument which is convenient to use, free of instrument level adjustment and capable of rapidly and accurately measuring structural surface occurrence. The gravity center type structural surface occurrence measuring instrument comprises a frame, a central partitioning plate and a spherical compass. The invention further provides a structural surface occurrence measuring method which comprises the following steps: A, placing the instrument on a structural surface horizontally; B, after the position of the central partitioning plate is stabilized, measuring a true dip direction angle; and C, measuring a true dip angle of the structural surface. By adopting the instrument and the method provided by the invention, the situation that a spirit level bubble is centralized while a compass edge is tightly close to the structural surface is not needed, or the dip angle does not need to be measured by adjusting a tubular spirit level or suspending hammer. The technical scheme of the invention is slightly affected by measurement environments and artificial factors, so that the measurement can be relatively accurately and rapidly implemented.

Description

technical field [0001] The invention relates to a method for measuring the occurrence of a structural surface and a center-of-gravity type measuring instrument for the occurrence of a structural surface, in particular to a method for measuring the occurrence of a structural surface and a center-of-gravity type measuring instrument for the occurrence of a structural surface applied in the field of civil engineering. Background technique [0002] In the field of civil engineering, structural planes refer to cracked and easily cracked surfaces in rock bodies, such as layers, joints, faults, schistoses, etc., also known as discontinuous surfaces. The occurrence of the structural surface refers to the extension orientation of the structural surface in space. Contains three elements, namely trend, inclination and inclination. Among them, azimuth: azimuth, also known as horizontal longitude (Azimuth (angle) abbreviated as Az), is one of the methods to measure the angle difference ...
