Description

Technical Field

[0001] This utility model belongs to the field of tunnel engineering testing technology, specifically relating to a portable grouting effect testing device. Background Technology

[0002] In tunnel construction, when traversing complex geological conditions such as aquifers, fault fracture zones, or karst areas, groundwater seepage and surrounding rock instability are major risks. Curtain grouting technology injects grout into the rock surrounding the tunnel outline to form a ring-shaped water-stopping reinforcement ring, which can effectively seal seepage channels, improve the integrity and impermeability of the surrounding rock, thereby avoiding water inrush and mudslide accidents and ensuring construction safety. However, the grouting effect is significantly affected by the degree of development of stratum fissures, the grout diffusion radius, and construction technology. If there are areas that are not filled densely or not covered, it may lead to local leakage or even structural failure. Therefore, accurate monitoring of the curtain grouting effect is a key link in ensuring project quality.

[0003] Traditional monitoring methods, such as core drilling or borehole imaging, require drilling and sampling after grouting. The effectiveness is assessed through core grout filling rate or video observation. While these methods are intuitive and reliable, they suffer from drawbacks such as cumbersome operation, long detection cycles, high costs, and significant formation disturbance. Furthermore, borehole sampling only reflects local point information, making it difficult to comprehensively evaluate the overall quality of the grout curtain. In recent years, ground-penetrating radar (GPR) has been introduced as a non-destructive detection technology. It rapidly acquires medium distribution information through electromagnetic wave reflection signals, achieving large-scale, high-resolution detection. Existing examples further demonstrate that using GPR to detect the grouting effect in water-rich, fractured surrounding rock is an effective method. In existing technologies, when using geological radar to monitor grouting effects, a detection platform mounted on a loader or a lift vehicle is typically used to transport personnel to the detection point. The worker holds the radar antenna device and places it against the grouting wall in front of the working face. As the loader or lift vehicle moves forward, the radar host acquires the signal transmitted by the radar antenna, thus completing the detection. However, this detection method not only has a low safety factor and low automation, but is also very cumbersome to operate and requires a large amount of manual labor. Furthermore, it is prone to problems such as difficulty in controlling the movement speed and stability, which leads to inaccurate detection data and analysis results that do not match reality, affecting the reliability of the detection results.

[0014] Compared with the prior art, the advantages of this utility model are: 1. This utility model uses a rotating mechanism to drive a lifting mechanism to perform horizontal rotation, which enables the ground radar to perform a circular scan along the working face, covering the outer area at the current height. The detection height is adjusted layer by layer by the lifting mechanism, and the circular scan is repeated after each layer is raised and lowered. The entire coverage detection of the grouting effect at the front of the working face can be completed without the need for an overall moving device. There is no need for manual climbing or external equipment to approach the working face, which reduces the risk of high-altitude operations and avoids the speed fluctuation problem when moving traditional loaders or lifting vehicles. It ensures the stability of radar signal acquisition, reduces manual intervention, reduces the risk of personnel operation, is easy to operate and has high detection efficiency, and improves the comprehensiveness of the overall quality assessment of curtain grouting. 2. This utility model uses an electric telescopic rod to drive the scissor lift to expand / retract, thereby realizing the lifting of the lifting plate. Then, through the superposition of the lifting of the scissor lift and the horizontal rotation of the rotating mechanism, the axial expansion / contraction of the working face can be achieved layer by layer scanning without detection blind spots. The scissor lift structure is stable in lifting and lowering, avoiding the influence of speed fluctuations on radar signal acquisition and improving the accuracy of detection data acquisition. 3. This utility model allows for adaptive adjustment of the distance between the first clamping plate and the elastic spring of the elastic clamping component, thereby quickly clamping the ground penetrating radar. The second clamping plate is driven by a bidirectional threaded rod to provide secondary reinforcement of the ground penetrating radar from the vertical direction. This design can adapt to radar equipment of different sizes and ensure the stability of the ground penetrating radar during the detection process, preventing displacement or detachment during mobile scanning, thus improving the reliability of data acquisition. By setting flexible rubber pads on the inner sides of the first and second clamping plates, the friction between the clamping plates and the ground penetrating radar can be effectively increased and the surface of the equipment can be protected.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0021] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] like Figure 1 and Figure 5As shown, a portable grouting effect detection device includes an integrated ground-penetrating radar 1, a clamping mechanism 2 for clamping and fixing the ground-penetrating radar 1, a lifting mechanism 3 connected to the clamping mechanism 2 and driving the clamping mechanism 2 to move up and down in the vertical direction, an adjustment component 4 set on the lifting mechanism 3 for adjusting the distance between the clamping mechanism 2 and the working face, a rotating mechanism 5 connected to the bottom of the lifting mechanism 3 for driving it to rotate left and right, a cross-shaped base 6 connected to the bottom of the rotating mechanism 5, and moving wheels 7 with brakes set at the four corners of the bottom of the cross-shaped base 6.

[0025] It should be noted that the integrated ground-penetrating radar 1 is a device that integrates the radar antenna and the radar host in the same housing 20. Due to its convenience, it is widely used in the existing technology. When using this device, the appropriate antenna frequency of the ground-penetrating radar 1 can be selected according to the grouting depth to be detected. When using the ground-penetrating radar 1 for detection, a display that is wirelessly connected to it should also be used so that the construction personnel can obtain the detection data in real time. A push rod can be vertically installed on the base plate to facilitate the construction personnel to move the detection device to the corresponding position.

[0026] When testing the effect of tunnel curtain grouting, this device first clamps and fixes the ground-penetrating radar 1 using the clamping mechanism 2. Then, the device is positioned at the axis of the sealing wall in front of the tunnel face. The distance between the clamping mechanism 2 and the sealing wall is finely adjusted by the adjusting component 4 so that the antenna of the ground-penetrating radar 1 is in contact with the sealing wall surface. Then, the lifting mechanism 3 is activated to lift the clamping mechanism 2 to the target height. The rotating mechanism 5 drives the ground-penetrating radar 1 to complete the circular detection at the current height. The lifting mechanism 3 descends to the next height layer, and the circular scan is repeated until the target area is covered, ensuring coverage without blind spots. After integrating the data from multiple circular scans, the curtain grouting quality effect is analyzed by software. This device can complete the full coverage detection of the grouting effect at the front of the tunnel face without the need for the entire moving device. It also eliminates the need for manual climbing or the use of external equipment to approach the tunnel face, reducing the risk of high-altitude operations and avoiding the speed fluctuation problem of traditional loaders or aerial work platforms. This ensures the stability of radar signal acquisition, reduces manual intervention, lowers the risk of personnel operation, is easy to operate, has high detection efficiency, and improves the comprehensiveness of the overall effect evaluation of curtain grouting.

[0027] like Figure 2As shown, the rotating mechanism 5 includes: a first bearing seat 8 respectively disposed on the front and rear upper surfaces of the cross-shaped base 6; a mounting column 9 rotatably connected to the first bearing seat 8 at both ends via bearings; a worm gear ring 10 fixedly sleeved in the middle of the mounting column 9; a worm 11 meshing with the worm gear ring 10; a second bearing seat 12 respectively disposed on the left and right upper surfaces of the cross-shaped base 6; and a power component 13 connected to one end of the worm 11 and driving it to rotate. The two ends of the worm 11 are rotatably connected to the second bearing seat 12 via bearings. The lifting mechanism 3 is connected to the mounting column 9.

[0028] It should be noted that the power component 13 is a commonly used forward and reverse motor in the prior art, and the motor model and power can be selected according to the actual situation; In use, the power component 13 drives the worm gear 11, which meshes with the worm wheel ring 10, causing the mounting column 9 to rotate horizontally around the axis. This drives the lifting mechanism 3 connected to the mounting column 9 to rotate horizontally left and right, meshing with the worm wheel ring 10 for transmission. The high reduction ratio of the worm wheel and worm gear 11 ensures that the rotation speed is controllable, avoiding the deviation of the ground radar 1 due to inertia, thereby improving the accuracy of detection.

[0029] like Figure 3 As shown, the lifting mechanism 3 includes: two sets of symmetrically arranged scissor lifts 14, mounting bases 15 respectively connected to both ends of the mounting column 9 and connected to the scissor lifts 14, lifting plates 16 connected to the top ends of the two sets of scissor lifts 14, connecting rods connected between the two sets of scissor lifts 14, and an electric telescopic rod 17 installed between the two sets of scissor lifts 14 for driving the scissor lifts 14 to expand or retract.

[0030] The upper and lower ends of the scissor lift 14 on the same side are hinged and slidably connected to the mounting base 15 and the lifting plate 16, respectively. The upper and lower ends of the other side are hinged to the mounting base 15 and the lifting plate 16, respectively. The upper end surface of the mounting base 15 and the lower end surface of the lifting plate 16 are provided with a first sliding groove 18. A first slider 19 is slidably connected in the first sliding groove 18. The scissor lift 14 is hinged to the first slider 19.

[0031] The electric telescopic rod 17 drives the scissor lift 14 to extend / retract, realizing the lifting of the lifting plate 16. Then, through the superposition of the lifting of the scissor lift 14 and the horizontal rotation of the rotating mechanism 5, the axial expansion / contraction of the working face is achieved layer by layer, without detection blind spots. The scissor lift 14 has a smooth lifting structure, avoiding the influence of speed fluctuations on radar signal acquisition and improving the accuracy of detection data acquisition. During the extension or retraction of the scissor lift 14, the first slider 19 slides synchronously in the first slide groove 18, reducing the shaking during the lifting process and improving the accuracy of data acquisition.

[0032] like Figure 4 As shown, the clamping mechanism 2 includes: an elastic clamping member and a reinforcing clamping member. The elastic clamping member includes: a hollow housing 20 with one end open, a sliding plate 21 slidably connected to the housing 20 at one end, two opposing first clamping plates 22 respectively connected to the ends of the housing 20 and the sliding plate 21, and an elastic mechanism connected between the housing 20 and the sliding plate 21 for driving the relative distance between the two first clamping plates 22 to shorten. The reinforcing clamping member is fixed on the housing 20.

[0033] Among them, such as Figure 5 As shown, the elastic mechanism includes: a plurality of mounting slots 23 formed on the sliding plate 21 along the sliding direction of the sliding plate 21, and a clamping spring 24 disposed in the mounting slot 23, one end of which is connected to the end of the mounting slot 23 and the other end of which is connected to the housing 20.

[0034] The clamping mechanism 2 can quickly clamp the grounding radar 1 using elastic clamping components, adapting to changes in radar size and providing basic fixation. The reinforcing clamping components can achieve adjustable secondary reinforcement of the grounding radar 1, resisting vibration or inertial displacement during the detection process. The synergistic effect of the elastic clamping components and the reinforcing clamping components achieves stable, efficient, and non-destructive fixation of the grounding radar 1, significantly improving the reliability and ease of operation of tunnel curtain grouting detection.

[0035] When the elastic clamping component is not clamped, the clamping spring 24 is in a naturally extended state, and the distance between the two first clamping plates 22 is the smallest. When the ground-penetrating radar 1 is placed between the two first clamping plates 22, the sliding plate 21 is pushed to slide within the housing 20, stretching the clamping spring 24 and causing the clamping spring 24 to generate a reverse elastic force. The elastic force of the clamping spring 24 drives the sliding plate 21 to rebound, causing the two first clamping plates 22 to automatically and quickly clamp the ground-penetrating radar 1. It should be noted that an appropriate spring stiffness should be selected according to the actual situation to ensure that the clamping force is moderate, so as to prevent damage to the equipment due to excessive tightness and to avoid loosening. The reinforcing clamping component includes: a fixing plate 25 connected to the side of the housing 20 away from the ground-penetrating radar 1; a second sliding groove 26 formed on the side of the fixing plate 25 near the ground-penetrating radar 1; a bidirectional threaded rod 27 rotatably connected at both ends in the second sliding groove 26; a second slider 28 threadedly connected to both ends of the bidirectional threaded rod 27 and slidably connected to the second sliding groove 26; a second clamping plate 35 respectively connected to the second slider 28; and a first rotating knob 29 rotatably fixedly connected to either end of the bidirectional threaded rod 27 through the side wall of the second sliding groove 26. The direction of the second sliding groove 26 is perpendicular to the sliding direction of the sliding plate 21.

[0036] When the reinforcing clamps are not reinforced, the spacing between the second clamping plates 35 is minimal, and they are not in contact with the ground-penetrating radar 1. When fixing the ground-penetrating radar 1, rotating the first knob 29 drives the bidirectional threaded rod 27 to rotate. The reverse threads at both ends of the bidirectional threaded rod 27 cause the two second sliders 28 to move towards each other along the second slide groove 26, thereby driving the second clamping plates 35 to come closer together and clamp the ground-penetrating radar 1. When it is necessary to remove the ground-penetrating radar 1, simply rotate the first knob 29 in the opposite direction. In order to ensure the clamping effect of the clamping plates and protect the surface of the ground-penetrating radar 1, flexible rubber pads 30 are provided on the opposite sides of the two first clamping plates 22 and the opposite sides of the second clamping plate 35. The flexible rubber pads 30 increase the friction between the clamping plates and the ground-penetrating radar 1.

[0037] like Figure 1 As shown, the adjustment assembly 4 includes: a third slide groove 31 formed on the lifting plate 16; an adjusting threaded rod 33 rotatably connected at both ends to the third slide groove 31; a third slider 32 threadedly connected to both ends of the adjusting threaded rod 33 and slidably connected to the third slide groove 31; and a second rotating knob 34 rotatably passing through the side wall of the third slide groove 31 and fixedly connected at either end of the adjusting threaded rod 33; the bottom surface of the fixing plate 25 is connected to the third slider 32.

[0038] In use, adjusting the threaded rod 33 drives the third slider 32 to move, which in turn drives the clamping mechanism 2 to move horizontally along the third slide groove 31, thereby controlling the distance between the clamping mechanism 2 and the sealing wall, so that the antenna of the ground radar 1 is in contact with the sealing wall surface, ensuring the best radar signal reception effect.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail can be made without departing from the spirit and scope of this utility model as defined in the appended claims.
