Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to geological survey equipment technical field, concretely relates to a geological survey geotechnical depth measuring device. BACKGROUND
[0002] The core of geotechnical engineering investigation is to use professional testing methods and means (such as drilling, in-situ testing, soil test, geophysical exploration, etc.) to conduct detailed investigation, research and analysis on the building site. The goal is first to identify the geological conditions of the proposed engineering area (including stratum structure, geotechnical properties, groundwater conditions and adverse geological effects, etc.), to assess the possible impact of engineering construction on the natural geological environment; secondly, to study the mechanism of building foundation, foundation and superstructure working together, and to propose engineering and technical measures to ensure that the foundation has sufficient strength, stability, and can control deformation within the allowable range; finally, the investigation work needs to accurately provide key design parameters such as foundation bearing capacity, to provide comprehensive and reliable engineering geology and geotechnical engineering basis for the design, construction of foundation and, if necessary, the foundation reinforcement scheme. For example, the prior art such as patent CN222207880 discloses a geotechnical depth measuring device, which realizes the synchronous measurement of the initial value of the distance sensor and the movement of the drill bit to the rock-soil inner wall through the setting of the starting mechanism. This design effectively protects the drill bit while significantly reducing the system error that may be introduced by traditional measurement methods, thereby improving the accuracy of the depth measurement result.
[0003] However, although the above measuring device has made progress in reducing depth measurement error, it still has a significant limitation in actual application scenarios: lack of effective stable support structure. In the process of high-speed rotation and powerful drilling of the drill bit in the rock-soil layer, the entire measuring device will be affected by strong reaction force, vibration and torque. If the device itself is not firmly connected or fixed to the ground or other stable reference, its own structure is prone to displacement, shaking or even overturning. This unstable state not only interferes with the normal operation of precision measuring elements such as distance sensors, causing real-time data distortion, but also directly damages the linearity of the drilling trajectory and the reliability of the measurement reference, thereby seriously reducing the accuracy and repeatability of the final geotechnical depth measurement data. Therefore, improving the overall stability of the device in dynamic drilling operation is the key improvement direction to ensure that its measurement accuracy advantage can be fully utilized.

[0034] In a preferred embodiment, as shown in Figure 1 、 Figure 2 and Figure 3 The fixed mechanism 3 further includes a fixed frame 31 provided on the outer wall of the support 1, the outer wall of the fixed frame 31 is provided with a mounting plate 32, the lower side of the mounting plate 32 is fixedly installed with a motor 33, the output end of the motor 33 is connected with a bidirectional screw rod 34, the bidirectional screw rod 34 is threadedly connected with a threaded block 35, and the outer wall of one end of the threaded block 35 is fixedly connected with a push rod 36.
[0035] In the above description, the motor 33 is rotated to drive the bidirectional screw rod 34 to rotate, and the two push rods 36 are driven to move towards or away from each other by the meshing force between the bidirectional screw rod 34 and the threaded block 35.
[0036] In a preferred embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The top end of the bottom plate of the support 1 is further connected with a spring 37, one end of the spring 37 away from the top end of the support 1 is connected with a force receiving block 38, the bottom end of the force receiving block 38 is provided with a connecting slide rod 39, and the bottom end of the connecting slide rod 39 is connected with the top end of the connecting plate 310.
[0037] In the above description, the two push rods 36 are extruded on the inclined surface of the force receiving block 38 on the side close to the push rod 36, the push rod 36 is extruded downward to make the spring 37 compressed, and then the force receiving block 38 moves downward, and then the connecting plate 310 drives the inserts 311 to move downward and insert into the soil to fix the device.
[0038] Specifically, as shown in Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the force block 38 is provided with a slope near one side of the push rod 36, and the slope is used in cooperation with the push rod 36.
[0039] Specifically, as shown in Figure 1 and Figure 2 , the bottom plate of the support 1 is further provided with a sliding groove 11, and the sliding groove 11 is used in cooperation with the connecting sliding rod 39, so that the connecting sliding rod 39 can slide up and down along the sliding groove 11 during adjustment.
[0040] In a preferred embodiment, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the number of the connecting plates 310 is four, and the connecting plates 310 are symmetrically distributed in pairs below the support 1, so as to uniformly support the support 1 during use.
[0041] In a preferred embodiment, as shown in the tapered insertion pins 311 are uniformly and equidistantly distributed at the bottom end of the connecting plate 310 Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , for inserting the insertion pins 311 into the soil below by adjusting the downward movement of the connecting plate 310 during use. Meanwhile, when the soil is hard and the insertion pins 311 cannot be inserted into the soil below by gravity, the upper end of the force block 38 is provided as a horizontal force receiving part, so that the insertion pins 311 can be inserted into the soil below by external hammering, thereby improving the stability of the device.
[0042] In a preferred embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the support 1 is further provided with a level 5, which is used for indicating the horizontal adjustment of the support 1 during use, so as to ensure the verticality of the drilling and the accuracy of the depth measurement.
[0043] In a preferred embodiment, as shown in Figure 1 and Figure 2 , the moving wheels 4 are symmetrically installed on the lower sides of the four corners of the bottom plate of the support 1, so as to facilitate the movement of the device.
[0044] The implementation principle of the geological exploration rock-soil depth measuring device is as follows:
[0045] After the device is moved to a suitable position, the motor 33 can be started, and the output end of the motor 33 will drive the bidirectional screw rod 34 to rotate. With the rotation of the bidirectional screw rod 34, the two threaded blocks 35 can be relatively moved. At this time, the threaded blocks 35 can drive the two push rods 36 to move synchronously. With the movement of the push rods 36, the stress blocks 38 can be contacted and extruded. The extruded stress blocks 38 can generate a downward moving force, so as to drive the connecting slide rod 39 to move downward. At the same time, the stress blocks 38 will extrude and compress the springs 37 during the downward movement. With the downward movement of the connecting slide rod 39, the connecting plate 310 and the dowel 311 can move downward. With the downward movement of the dowel 311 until the dowel 311 is inserted into the soil, the support 1 can be fixed and positioned by the four surrounding dowels 311, so as to fix and position the overall device. When the soil is hard, the dowel 311 cannot be inserted into the lower soil by gravity. The upper end of the stress block 38 is a horizontal stress part. The dowel 311 can be inserted into the lower soil by external hammering. In this way, the device can be prevented from moving during the soil drilling process by the drill bit, so as to improve the stability of the device and the accuracy of the measurement data.
[0046] After the measurement is completed, the bidirectional screw rod 34 can be reversed, so that the bidirectional screw rod 34 drives the threaded blocks 35 to move close to each other. In this way, the push rods 36 can gradually move away from the stress blocks 38. At this time, the stress blocks 38 lose extrusion and positioning, and can be driven by the rebound of the springs 37 to move upward and reset. With the reset movement of the connecting slide rod 39, the dowel 311 can move upward, so as to leave the soil and release the positioning of the device.
[0047] It should be noted that in the above description, the motor 33 is a prior art known to those skilled in the art, and the specific model can be selected according to the use requirement, which will not be repeated here.
[0048] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application.
