Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of geotechnical engineering, and particularly relates to a drilling azimuth angle and inclination angle measuring device and a measuring method which can be used in the complex environment of geotechnical engineering such as mines, hydropower stations, railway and highway tunnels, water diversion tunnels and the like. BACKGROUND

[0002] In geotechnical engineering, drilling is often performed to install measuring or monitoring devices, such as microseismic sensors, acoustic emission sensors, disturbance stress meters, multi-point displacement meters and a large number of sensors. These sensors are generally installed at the bottom of a hole or near the bottom of a hole in the hole, and the coordinate position of the sensor in the hole needs to be determined when the installation is performed.

[0003] In most cases, there is no mobile signal and no GPS positioning available in the cavern, and only basic equipment such as a total station can be used to measure the coordinates of the space that can be touched by hand in the cavern. The position of the total station is known, and the prism is placed at the position to be measured, so that the position to be measured can be obtained at the total station. Therefore, only the coordinates of the hole mouth can be measured, and the coordinates in the hole cannot be measured.

[0004] Before drilling, the angle of the drilling hole is estimated or roughly measured, but the accuracy of the measuring equipment of the construction team cannot be guaranteed. The equipment will also produce a certain deviation due to external force when drilling, and the angle needs to be re-measured later. Usually, the coordinates of the hole mouth are measured first, and then the azimuth angle and inclination angle of the drilling hole are measured using a compass and the like, and the distance of the sensor from the hole mouth is determined in advance to calculate the coordinates of the position of the sensor in the hole.

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0042] It should be noted that all directionality indications in the embodiments of the present application are only used to explain the relative position relationship and movement between components in a certain posture, and if the certain posture changes, the directionality indications will also change accordingly.

[0043] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and arrangements of specific examples are described in the following. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the application of other processes and / or the use of other materials.

[0044] In the prior art, the measurement of the azimuth and inclination of the borehole will encounter many problems, which will make the angle measurement inaccurate, which is specifically manifested in:

[0045] First, the angle measuring device, such as a compass, is usually smaller than the borehole diameter, and when measuring the angle, the pointer cannot be consistent with the borehole axis, and the left and right or up and down shaking will cause the angle to deviate.

[0046] Second, when measuring the inclination, it is difficult to make the instrument completely vertical, and the inclination measurement deviates.

[0047] Third, when measuring the azimuth, the compass is held, and it is not easy to stabilize when the compass is horizontal, and the instrument reading is unstable.

[0048] Fourth, there are sometimes live wires or electrical equipment near the hole, and these devices will generate an electromagnetic field near the live state, which will interfere with the azimuth measurement of the compass and other measuring instruments.

[0049] These deviations caused by angle measurement will cause great errors in the calculated sensor coordinates, so it is extremely necessary to invent a device for accurately measuring the azimuth and inclination of the borehole.

[0050] The embodiments of the present application provide a borehole azimuth and inclination measuring device and a measuring method, which aims to at least solve the technical problem that the azimuth and inclination measurement is inaccurate due to the complexity of the chamber in the prior art.

[0051] First, the embodiments of the present application disclose a borehole azimuth and inclination measuring device.

In combination with Figures 1-3 The coupling fixing device, the vertical calibration device and the extension device in the embodiment of the present application all have a first end and a second end. The first end of the coupling fixing device can be fixed in the drill hole 3 to be tested. The second end of the coupling fixing device and the first end of the vertical calibration device are rotatably connected. The second end of the vertical calibration device and the first end of the extension device are telescopically connected. The second end of the extension device is arranged on the instrument platform.

[0054] In combination with Figure 2 and Figure 3 The coupling fixing device in the embodiment of the present application comprises a first rod body 4 and a fixing support 8. The first rod body has a plurality of fixing supports 8 spaced apart on the circumferential surface. The fixing support 8 comprises a support piece, a sliding sleeve 806 and a plurality of connecting rods 805. The connecting rods 805 are sequentially and rotatably connected along the axial direction of the first rod body 4.

Therefore, by controlling the movement of the sliding sleeve 806 on the first rod body 4, the plurality of connecting rods 805 can be extended and retracted, and the radius of the expanded support piece can be controlled. In practice, the expanded support piece can abut against the inner wall of the drill hole 3, so as to fix the coupling fixing device in the drill hole 3.

When the support piece abuts against the inner wall of the drill hole, the support plate 807 of the support piece abuts against the inner wall of the drill hole, so as to fix the coupling fixing device in the drill hole.

[0056] Further, the surface of the support plate 807 of the support piece, which faces away from the first rod body 4, is provided with anti-skid tooth patterns. When the coupling fixing device is fixed in the drill hole, the anti-skid tooth patterns can prevent the support plate 807 of the support piece and the inner wall of the drill hole from sliding or rotating, so as to improve the firmness of the coupling fixing device fixed in the drill hole.

[0057] In combination with Figure 2In the embodiment of the present application, the end of the connecting rod located at the front end of the first rod body 4 can be connected to a fixing sleeve 801, which can be fixedly arranged at the front end of the first rod body 4.

The end of the driving member 9 away from the sliding sleeve is provided with a knob 901. By rotating the knob 901, the driving member 9 can be advanced and retreated along the axial direction of the first rod body 4. That is, the change of the radius of the fixed support 8 can be controlled in a manual manner.

[0059] In combination with Figure 2 And Figure 3 It should be noted that the fixed support 8 in the embodiment of the present application can be arranged at intervals around the axis of the first rod body 4, and preferably three are arranged.

The rear end of the first rod body 4 and the front end of the second rod body 5 can be connected through a fixing screw 12. By adjusting the tightness of the fixing screw 12, whether the rear end of the first rod body 4 and the front end of the second rod body 5 rotate or not can be controlled.
