Description

Technical Field

[0001] The utility model belongs to the technical field of measurement assistance, and particularly relates to a geological compass auxiliary device for measuring the attitude of rock mass structural planes, which is used for measuring the attitude of rock mass structural planes. Background Technique

[0002] An existing device for measuring the attitude of rock mass structural planes can measure the attitude in geological conditions where it is not convenient to directly measure with a geological compass. However, it does not effectively solve the problem that the random rotation when using a geological compass to measure the dip angle makes the measured dip angle prone to be a false dip angle. There is also a device for measuring the attitude with a geological compass. Although this device can realize the extension and indirect measurement of the structural plane, and solve the problem that the exposed interface of the linear outcropping structural plane is small, resulting in the compass being unable to fit and large measurement errors, it does not effectively solve the problem that the random rotation when using a geological compass to measure the dip angle makes the measured dip angle prone to be a false dip angle. Content of the Utility Model

The technical problems to be solved are: solving the problems of difficult measurement, inaccurate measurement results, and limited applicable sites for rock mass structural planes with insufficient exposed space in the work of measuring rock mass structural planes with a single geological compass in the past; and also solving the problem that the measured dip angle of the rock mass structural plane is prone to be a false dip angle.

[0004] To solve the above technical problems, the utility model provides a geological compass auxiliary device for measuring the attitude of rock mass structural planes, which is characterized in that: it includes a structural plane alignment plate, a measurement carrier plate, a dip angle measurement groove, and a strike measurement groove; the ends of the structural plane alignment plate and the measurement carrier plate are rotationally connected and are all in one plane. The shape of the measurement carrier plate is circular, which is used to assist the geological compass to measure the attitude of rock mass structural planes with insufficient exposed space, and is provided with a dip angle measurement groove and a strike measurement groove on it.

[0005] Beneficial Effects: The utility model extends the rock mass structural plane with insufficient exposed space to expand the measurement space, so as to assist the geological compass to measure the attitude of rock mass structural planes with insufficient exposed space in geotechnical engineering, including three attitude elements such as dip angle, strike, and trend; at the same time, this auxiliary device can solve the problem that the measured dip angle of the rock mass structural plane is prone to be a false dip angle, making the measured dip angle closer to the true dip angle.

[0006] In summary, this auxiliary device can overcome the defects of difficult measurement, inaccurate measurement results, and limited applicable sites of rock mass structural planes with insufficient exposed space in the work of measuring rock mass structural planes with a single geological compass in the past, so as to achieve the purpose of better measuring rock mass structural planes and mastering the stability of rock masses.

[0010] To make the objectives, content, and advantages of the present utility model clearer, the following further describes in detail the specific embodiments of the present utility model.

[0011] A geological compass auxiliary device for measuring the attitude of rock mass structural planes proposed by the present utility model includes a structural plane alignment plate 1, a No. 1 rotary button 2, a measurement carrier plate 3, a dip measurement groove 4, a No. 2 rotary button 5, and a strike measurement groove 6;

[0012] This device is made of a thin and light plate-shaped rigid material with a smooth surface treatment.

[0013] The structural plane alignment plate 1 is in the shape of an equilateral triangle and is used for parallel contact with the rock mass structural plane 7 with insufficient exposed space; the rock mass structural plane is the rock mass joint, usually the crack of the exposed rock mass; multiple groups of rock mass structural planes will be formed on the exposed rock mass. The bottom edge of the structural plane alignment plate 1 is inserted into the rock mass structural plane to achieve parallel contact.

[0014] The No. 1 rotary button 2 is used to rotatably connect one corner of the structural plane alignment plate 1 and the end of the measurement carrier plate 3, so that both are in the same plane, and the measurement carrier plate 3 can rotate a certain angle in a narrow measurement space, facilitating measurement;

[0015] The measurement carrier plate 3 is in the shape of a circle and is used to assist the geological compass in measuring the attitude of the rock mass structural plane 7 with insufficient exposed space, and is provided with a dip measurement groove 4 and a strike measurement groove 6 thereon;

[0016] The No. 2 rotary button 5 is used to rotatably connect the measurement carrier plate 3 and the dip measurement groove 4;

[0017] The dip measurement groove 4 is used to measure the dip angle of the rock mass structural plane 7 with insufficient exposed space, and it can rotate freely by 360° around the No. 2 rotary button 5, facilitating the measurement personnel to find the true dip line during the process of freely rotating the geological compass by 360° with the No. 2 rotary button 5 as the center, overcoming the obstacle that the rotation randomness in the past when using the geological compass to measure the dip angle makes the measured dip angle easy to be a false dip angle, and making the measured result closer to the true dip angle;

[0018] The inclination measuring groove 6 is used to measure the inclination of a rock structure surface 7 with insufficient exposed space (note: the strike and the inclination are always perpendicular, and the strike can be obtained based on the inclination).

[0019] Preferably, the device is made of a thin and light plate-like rigid material to avoid deformation due to force during the measurement process, which may lead to inaccurate measurement results; its surface is smoothed so that the device can better contact with the rock structure surface in parallel.

[0020] Preferably, the connection strength of each rotating button should be tighter so that the connected objects are all on the same plane. At the same time, it can avoid rotation after the angle is set during the measurement process, which affects the measurement efficiency.

[0021] Preferably, the structure surface alignment plate is in the shape of an equilateral triangle, so as to facilitate parallel contact with the rock structure surface with insufficient exposed space.

[0022] Preferably, the measuring carrier plate is circular in shape, and is used to assist the geological compass in measuring the occurrence of rock structure surfaces with insufficient exposed space.

[0023] Working principle: In geotechnical engineering 9, there are usually certain rock structure surfaces 7 distributed. The rock structure surface 7 is directly related to the stability of the geotechnical engineering 9. Therefore, it is necessary to measure the occurrence (including dip, inclination and strike) of the rock structure surface 7 to better evaluate its stability.

[0024] First, according to the results of the on-site investigation, the rock structure surface 7 with insufficient exposed space is found, and the structural surface alignment plate 1 of the device is placed on the rock structure surface 7 with insufficient exposed space, in parallel contact with it, and at the same time, the measuring carrier plate 3 and the structural surface alignment plate 1 are both on the same plane; turn the 1# rotating button 2 so that the measuring carrier plate 3 can be rotated and adjusted to a certain angle in the narrow measuring space, which is convenient for subsequent measurement; the measuring carrier plate 3 is used to assist the geological compass in measuring the occurrence of the rock structure surface 7 with insufficient exposed space, and it mainly includes a dip measuring slot 4 and a dip measuring slot 6 connected by a 2# rotating button 5, which are respectively used to measure the dip and dip of the rock structure surface 7 with insufficient exposed space.

[0025] according to Figure 1 , 2 As shown, the geological compass is placed in the inclination measuring slot 4, and the inclination measuring slot 4 is freely rotated 360° with the 2# rotating button 5 as the center to find the true inclination line, and the movable wrench at the bottom of the geological compass is turned to make the bubble in the long level centered, and the inclination result measured by the geological compass is read, which is the true inclination of the rock structure surface 7 with insufficient exposed space, which can solve the problem that the inclination measured by a single geological compass in the past is easy to be a false inclination;

[0026] Then place the upper housing of the geological compass in the dip measurement groove 6, close to the measurement carrier plate. Rotate and adjust its lower housing through the connecting hinge on the geological compass to make the bubble in the circular level centered. Read the dip result measured by the geological compass, which is the dip of the rock mass structural plane 7 with insufficient exposed space, and thus obtain its strike (note: the strike is always perpendicular to the dip, and the strike can be obtained based on the dip).

[0027] The principle and structure of the present utility model are simple, the cost is low, the operation is convenient, and the practicability is strong. It can assist the geological compass to measure the occurrence of the rock mass structural plane with insufficient exposed space in geotechnical engineering, including three elements of occurrence such as dip angle, dip, and strike. At the same time, it can solve the problem that the measured dip angle of the rock mass structural plane is easily a false dip angle in the previous structural plane measurement work, make the measured dip angle closer to the true dip angle, and the measurement result is more accurate, so as to achieve the purpose of better measuring the rock mass structural plane and mastering the rock mass stability.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
