Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a device for detecting the thickness of sediment during foundation engineering construction. Background Technology

[0002] In foundation engineering construction, pile foundations are a common form of deep foundations. The construction quality of pile foundations directly determines the stability and safety of the superstructure, and the thickness of sediment at the bottom of the pile hole is one of the key indicators affecting the bearing capacity of the pile foundation.

[0003] Currently, the commonly used methods for detecting sediment thickness in the industry mainly include the traditional hammer method, borehole sampling method, and early laser detection method. However, these methods all have significant defects in practical applications and are difficult to meet the requirements of modern engineering for detection accuracy, efficiency, and adaptability. The traditional hammer method has significant limitations: this method relies on manual operation to lower the hammer to the bottom of the pile hole and judge the sediment thickness by the feel of the hammer when it contacts the sediment or by rope markings. The operation process is highly dependent on human experience. Inconsistent control of the hammer's lowering speed and force can easily cause the hammer to collide with the side wall of the pile hole or sink too deep into the sediment layer, resulting in measurement errors. Moreover, each detection takes a long time, which seriously affects the construction progress. Furthermore, if there is sewage in the pile hole, it will affect the vision and further affect the measurement accuracy.

[0004] The adaptability and accuracy of laser detection methods are insufficient: Although existing laser detection devices can achieve non-contact detection through the principle of laser ranging, their structural design has obvious defects: First, the support structure has poor stability, and most of them use fixed brackets, which cannot flexibly adjust the height and level on uneven construction sites, resulting in the laser emitter tilting and the detection data being distorted; Second, there is a lack of effective light protection, and strong light in outdoor construction will interfere with the laser signal reception, reducing the detection accuracy; Third, the extension structure lacks flexibility, and it is impossible to flexibly adjust the horizontal position of the laser emitter according to the pile hole spacing and location, especially for some larger pile holes, where it is dangerous for workers to stand on the edge during detection.

[0020] Preferably, the light-shielding frame can move the light-shielding cloth to the rear, left, and right sides of the detection frame.

[0021] The present invention proposes a device for detecting the thickness of sediment in foundation engineering construction. Compared with traditional methods such as manual hammer testing and manual handheld laser testing, the advantages of the present invention are as follows:

[0022] 1. Offers both excellent stability and flexibility, making it suitable for complex construction sites.

[0023] This invention features an adjustable support structure. On one hand, the extension length of the outriggers can be adjusted by pulling the lever to adapt to construction surfaces with varying flatness, allowing for flexible adjustment of the support height. On the other hand, the symmetrical support units on the four sides form a stable support structure, preventing the device from tipping over and providing a solid foundation for subsequent testing, thus solving the problems of "unstable support and easy deviation" in traditional testing methods.

[0024] 2. Highly convenient for storage and expansion, reducing handling and operation costs.

[0025] The extended structure design of this invention has the dual characteristics of "retractable + extendable": when idle, the first extension arm can slide along the locking block through the slide rail and be stored in the main seat, and the second extension arm is inserted back into the first extension arm to achieve parallel and compact storage and reduce storage space; when in use, the first extension arm is flipped to a vertical state on the locking block through the expansion groove, and the extension length of the second extension arm is adjusted by the second screw to quickly form an extendable hanger support, without complicated assembly, solving the problems of "scattered parts, difficult storage, and time-consuming assembly" in traditional testing.

[0026] 3. Wide adaptability and precise angle adjustment, covering multiple testing scenarios.

[0027] The detection component of this invention has two advantages: First, it has wide adaptability. By using the third screw and rubber pad in the mounting frame, it can hold different models of laser detector bodies without replacing the entire detection structure. Second, it has precise angle adjustment. The motor drives the mounting frame to rotate around the shaft, which can precisely adjust the laser detection orientation according to the pile hole position requirements, avoiding errors caused by manual adjustment and solving the problems of "narrow adaptability and difficult angle control" in traditional detection.

[0028] 4. Automated level adjustment reduces reliance on human experience.

[0029] This invention utilizes a collaborative design of electric push rods, universal joints, and a level detector. The level detector senses the tilt state of the detection components in real time. After the signal is transmitted to the main body of the power supply control box, the three electric push rods automatically extend and retract in coordination. The universal joint drives the stabilizing plate to adjust the levelness without manual intervention, thus achieving automated level adjustment and solving the problem of traditional detection methods that "rely on human experience and have large level adjustment errors".

[0030] 5. Strong anti-interference capability under strong light, ensuring stable detection accuracy.

[0031] The light-shielding component of this invention specifically addresses the problem of strong light interference: First, the light-shielding frame can move along the sleeve arm, causing the light-shielding cloth to switch to the rear, left, or right side of the detection frame to adapt to strong light from different directions; second, the expansion range of the light-shielding cloth can be adjusted by moving the curtain seat to ensure that strong light is effectively blocked; and the light-shielding frame can be quickly fixed in position by tightening screws, making operation convenient and ensuring that the laser detector body can still output accurate data in strong light environments, solving the problems of "strong light interference and unstable accuracy" in traditional laser detection.

[0032] 6. Construction safety is significantly improved, and personnel risks are reduced.

[0033] This invention uses a hanger with an extended structure to support the detection components above the pile hole. Operators do not need to approach the edge of the pile hole; they can operate the system from the touch screen of the power supply control box next to the main control unit. This spatially isolates personnel from the danger zone, significantly reducing the risk of falls and solving the problem of traditional detection methods where "personnel are close to the pile hole, posing a significant safety hazard."

A pair of springs 158 are symmetrically arranged on both ends of the pull seat, and the other end of the springs 158 is fixedly connected to the card holder 156. The locking rod 159 is fixedly arranged in the middle of the pull seat, and one end of the locking rod 159 is movably inserted into the locking hole 6 of the support leg 153. The support leg 153 is supported by the flip arm 151, and the connecting arm 154 is supported by the flip seat 152. The connecting arm 154 and the support leg 153 are movably connected by the movable rod 155 to form a triangular support, and can be displaced according to the flip of the support leg 153 to adjust the locking position of the locking rod 159 on the card holder 156.

[0049] More specifically, the support unit 15 provides stable support for the support structure 1 through a triangular connection, and achieves height adjustment and locking through the linkage of "hand-pulled seat 157-spring 158-locking rod 159". It is easy to operate and adaptable to construction sites with different flatness, providing a reliable support foundation for the accurate detection of the entire detection device.

[0050] As a preferred embodiment, the extension structure 2 further includes a first extension arm 21, a pair of second screws 22, a second extension arm 23, a pair of fixing bolts 24, a bearing plate 25, three electric push rods 26, three universal joints 27, a stabilizing plate 28, and a sleeve 29.

[0051] One end of the first extension arm 21 movably passes through the main pipe seat 11, and the middle of the left and right side walls of the first extension arm 21 is provided with a slide rail that fits into the locking block 12. One end of the slide rail is provided with an expansion groove 8. The slide rail of the first extension arm 21 is fitted onto the locking block 12, and one end of the first extension arm 21 is flipped on the locking block 12 through the expansion groove 8.

The first extension arm 21 is raised from inside the main pipe seat 11. Then, with the help of the expansion groove 8 at the end of the slide, the first extension arm 21 is flipped on the locking block 12. That is, the first extension arm 21 is flipped at the flipping opening 16, making the first extension arm 21 perpendicular to the main pipe seat 11. Then, the first extension arm 21 passes through the flipping opening 16 of the main pipe seat 11 and is positioned by the first screw 13. The extension length of the second extension arm 23 inside the first extension arm 21 is adjusted by the second screw 22. The second extension arm 23 supports the bearing plate 25. The tilt of the stabilizing plate 28 is adjusted by the telescopic control of the electric push rod 26, keeping the detection component 3 installed on the sleeve 29 horizontal.

[0052] More specifically, the extension structure 2 achieves flexible adjustment of the detection position through "two-stage telescopic + vertical flipping" and achieves automatic calibration of the levelness through "three-point support + electric control". The structure is compact and easy to operate, which can not only adapt to the detection needs of foundation pile holes with different diameters and depths, but also effectively eliminate the impact of uneven construction site on detection accuracy, providing reliable transmission and support guarantee for accurate detection of sediment thickness.

[0053] As a preferred embodiment, the detection structure further includes a detection component 3 and a light-shielding component 4. The detection component 3 is fixedly mounted on the sleeve 29, and the light-shielding component 4 is detachably mounted on the detection component 3 and can rotate on the detection component 3. The detection component 3 is used to detect depth distance by laser, and the light-shielding component 4 is used to block strong external light, so that the wall surface will not cause the laser equipment to detect inaccurately due to external light.

[0054] As a preferred embodiment, the detection component 3 further includes a detection frame 31, two pairs of mounting tubes 32, a motor 33, a horizontal detector 34, a mounting frame 35, a pair of third screws 36, a pair of rubber pads 37, a laser detector body 38, and three sleeve arms 39.

The two ends of the shafts movably pass through the left and right side walls of the detection frame 31, and one shaft is connected to the drive end of the motor 33. A pair of third screws 36 are respectively screwed into the middle of the front and rear side walls of the mounting frame 35. A pair of rubber pads 37 are respectively movable.

Three sleeve arms 39 are fixed at one end to the other end of three mounting tubes 32, and are located on the left, right, and rear sides of the detection frame 31. The other end of each sleeve arm 39 has a T-shaped structure with an arc-shaped wall. The mounting tubes 32 connect to the sleeves 29, and also support the motor 33. The motor 33, when activated, causes the mounting frame 35 to rotate, adjusting the ray direction of the laser detector body 38 within the mounting frame 35. The three sleeve arms 39 are positioned on the three side walls of the detection frame 31, facilitating the movement and reversal of the light-shielding component 4. The tilt is automatically sensed by the horizontal detector 34, and the electric push rod 26 is activated to adjust the level.

[0056] More specifically, the detection component 3 achieves the functions of "adjustable angle, controllable level, and accurate detection" through modular design. It can not only adapt to the detection of sediment in foundation pile holes of different depths and diameters, but also eliminate the impact of uneven construction site on detection accuracy through level monitoring and automatic calibration. At the same time, the detachable design of the laser detector body 38 facilitates maintenance and replacement, and the T-shaped structure of the arc end face of the sleeve arm 39 provides flexible adaptation for the light-shielding component 4. The overall structure is compact and easy to operate, meeting the actual needs of on-site detection in foundation engineering.

[0057] As a preferred embodiment, the light-shielding component 4 further includes a light-shielding frame 41, a tightening screw 42, several curtain bases 43, and a light-shielding cloth 44.

[0058] The light-shielding frame 41 is an H-shaped semi-circular slide rail, and rotating grooves 102 are provided in the middle of both the outer and inner walls of the light-shielding frame 41. The light-shielding frame 41 is movably fitted onto the other end of one of the sleeve arms 39 through the rotating grooves 102 on the inner wall. The tightening screw 42 is movably screwed onto the middle of the upper wall of the light-shielding frame 41, and the tightening screw 42 can fit against the sleeve arm 39. Several curtain seats 43 are respectively movably embedded in the rotating grooves 102 on the outer wall of the light-shielding frame 41, and the curtain seats 43 are... 3. The curtain base 43 is fixed at one end near the light-shielding frame 41 by bolts, and one end of the light-shielding cloth 44 is fixedly connected to the curtain base 43. The arc-shaped light-shielding frame 41 can slide on the sleeve arm 39 to realize the position adjustment of the light-shielding frame 41 to block the rear, left, or right sides. The light-shielding frame 41 is fixed on the sleeve arm 39 by the tightening screw 42. The light-shielding cloth 44 can be folded and stored or opened by the curtain base 43 sliding in the rotating groove 102.

[0059] More specifically, the light-shielding component 4, through the design of "reversible light-shielding frame 41 + retractable light-shielding cloth 44", achieves flexible adjustment of the direction and range of strong light blocking, adapting to the complex lighting environment in outdoor construction; at the same time, it adopts lightweight and wear-resistant materials to ensure the durability of the component on the construction site; it is easy to assemble and operate, and can complete the reversal and light-shielding adjustment without professional tools, providing reliable light protection for the accurate detection of the laser detector body 38.

[0060] As a preferred option, the blackout fabric 44 is further folded or opened by moving the curtain base 43.

[0061] As a preferred option, the light shield 41 can further move the light shield 44 to the rear, left and right sides of the detection frame 31.

[0062] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0063] Working principle:

[0064] S1. When using the equipment, by holding the bracket 156 in the support unit 15 and suspending the fingers on the pull seat 157, by making a fist, the pull seat 157 is pulled by the fingers, causing the pull seat 157 to move in the pull groove 7 of the bracket 156 and compressing the spring 158. At this time, the locking rod 159 disengages from the locking hole 6 of the support leg 153, and can then apply force to drive the support leg 153 to rotate between the flip arms 151. At the same time, the rotation of the support leg 153 will drive the connecting arm 154 to rotate on the flip seat 152, and one end of the connecting arm 154 slides in the moving groove 5 on the side wall of the support leg 153 by means of the movable rod 155. As the support leg 153 rotates and adjusts its position, the locking rod 159 is finally inserted into the locking hole 6 by the force of the spring 158 to lock and fix it, so as to achieve stable support of the support leg 153, the connecting arm 154 and the main pipe seat 11 forming a triangular connection.

[0065] S2. After opening the support leg 153, the support structure 1 can be placed on the ground, and the extension structure 2 can be opened; that is, manually pull the first extension arm 21 upward, the first extension arm 21 slides in the main pipe seat 11, causing the end expansion groove 8 to move to the locking block 12. With the help of the space of the expansion groove 8, the locking block 12 can be flipped in the expansion groove 8, that is, the first extension arm 21 is moved to the top of the main pipe seat 11 and then flipped 90 degrees. When the first extension arm 21 is perpendicular to the main pipe seat 11, the first extension arm 21 passes through the flip opening 16. At this time, the first extension arm 21 can be tightened and fixed by the first screw 13.

[0066] S3. Secondly, according to usage requirements, the extension length of the second extension arm 23 within the first extension arm 21 can be adjusted to adjust the overall length of the support, and the second extension arm 23 is fixed by the second screw 22;

[0067] S4. Then, install the corresponding laser detector body 38 in the detection assembly 3, embed the laser detector body 38 into the mounting frame 35, and clamp and fix it with the rubber pad 37 by rotating the third screw 36; then connect the motor 33, the horizontal detector 34 and the electric push rod 26 to the power supply control box body 14 through the second adapter cable 101 and the first adapter cable 9 respectively, and the laser detector body 38 can be opened for measurement.

[0068] S5. During measurement, the laser detector body 38 can be positioned above the pile hole after the internal sewage has been drained, supported by the main structure and extended by the extension structure 2. The laser detector body 38 illuminates the internal surface to achieve a measurement distance of L. The thickness of the sediment can be obtained by subtracting L from the depth Y of the pile hole.

[0069] S6. If there is strong external light interference, the sunlight can be blocked by installing a light-blocking component 4. That is, an arc-shaped light-blocking frame 41 is installed by the sleeve arm 39, and the curtain seat 43 moves in the rotation groove 102 of the light-blocking frame 41 to open or fold the light-blocking cloth 44. The light-blocking frame 41 can be rotated by the sleeve arms 39 which are set at equal intervals, so that the light-blocking frame 41 is located on the rear side or the left and right sides, and is fixed by the tightening bolts to adjust the direction of light blocking.

[0070] S7. During measurement, if the level detector 34 on the mounting tube 32 detects that the detection frame 31 is not level, the electric push rod 26 on the bearing plate 25 will be activated to extend and retract, and with the help of the flip-out effect of the universal joint 27, the tilt of the upper stabilizing plate 28 will be adjusted, thereby adjusting the level of the detection component 3 set through the sleeve 29.

[0071] S8. During the detection process in a horizontal state, the motor 33 can also be started to drive the mounting frame 35 to rotate, and adjust the laser detector body 38 to irradiate and detect different orientations and angles inside the pile hole.

[0072] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
