Description

Technical Field

[0001] This utility model relates to the field of acoustic logging pipe technology for pile foundations, and in particular to the installation structure of ultra-long acoustic logging pipes for pile foundations. Background Technology

[0002] In modern large-scale construction projects, bridges and high-rise buildings, the application of ultra-long pile foundations is becoming increasingly widespread. As a key supporting part of the building structure, the quality of ultra-long pile foundations is directly related to the stability and safety of the entire building. Sonic logging tubes are crucial in the quality inspection of ultra-long pile foundations, providing a channel for ultrasonic testing. By detecting the propagation of ultrasonic waves in the pile concrete, it is possible to accurately determine whether there are defects inside the pile.

[0003] However, the traditional installation of ultra-long pile foundation sonic logging tubes mainly includes the sonic logging tube itself, connecting components, and auxiliary positioning devices. During installation, the sonic logging tube is fixed to the outside of the main reinforcement of the steel cage according to the design requirements. It is then firmly fixed to the steel cage by welding the sonic logging tube to the U-shaped steel bar clips before lowering the sonic logging tube. However, the traditional installation method has many drawbacks. The sealing reliability of the connection is poor, which can lead to grout leakage and affect the accuracy of the test results. Existing technologies can achieve a sealed connection through connecting sleeves and sealing rubber rings to prevent grout from seeping in and affecting the test. However, the existing technology uses threaded connections, which requires operators to twist the sleeve to fit the sleeve and the sonic logging tube. This makes installation difficult, cannot achieve rapid installation, has a high dependence on manual operation, low construction efficiency, and makes it difficult to guarantee quality stability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an installation structure for ultra-long pile foundation sonic logging tubes, aiming to improve the problems of high installation difficulty, inability to achieve rapid installation, high dependence on manual operation, low construction efficiency, and difficulty in ensuring quality stability in the existing technology.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an ultra-long pile foundation sonic logging pipe installation structure, including a pile frame and pipes. Multiple fixing sleeves are fixedly connected to the bottom of the inner wall of the pile frame. Multiple pipes on the lower side are fixedly connected to corresponding fixing sleeves.

Two strip grooves are opened on the left and right sides of the inner walls of each sleeve. Trapezoidal blocks are slidably connected to the inner walls of each strip groove. Springs are fixedly connected to the opposite sides of each trapezoidal block. The opposite sides of each spring are fixedly connected to the corresponding strip groove. Adjacent sides of each trapezoidal block are respectively engaged with corresponding retaining rings. A protective mechanism is provided at the top of the inner wall of the pile frame to prevent debris from entering the pipe during operation.

[0007] The protection mechanism includes multiple connecting rods, which are respectively fixedly connected to the top of the inner wall of the pile frame. The same fixing ring 2 is fixedly connected between adjacent connecting rods, and the same fixing ring 1 is fixedly connected to one adjacent end of the multiple connecting rods. A rotating ring is rotatably connected to the top of the inner wall of the fixing ring 1. Multiple fixing rods 1 are fixedly connected around the outer wall of the rotating ring. Multiple shielding covers are fixedly connected to the far ends of the multiple fixing rods 1. The outer walls of the multiple pipes on the upper side are slidably connected to pipe sleeves, and strip rings are fixedly connected to the middle of the outer walls of the multiple pipe sleeves. The strip rings are fixedly connected to the pipe sleeves and connecting rods.

[0008] As a further description of the above technical solution:

[0020] Through the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the fixing sleeve at the bottom of the inner wall of the pile frame is connected to the pipeline, providing a stable bottom support for the sonic logging pipe. The sleeve, retaining ring, rubber ring and trapezoidal locking block components between adjacent pipelines work together.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of an ultra-long pile foundation sonic logging pipe installation structure, including a pile frame 1 and pipes 16. The pile frame 1 is used for the stability of the entire device. Multiple fixing sleeves 15 are fixedly connected to the bottom of the inner wall of the pile frame 1. Multiple pipes 16 on the lower side are fixedly connected to the fixing sleeves 15. This structure is used to stabilize the position of the sonic logging pipe to achieve accurate measurement. A sleeve 3 is provided between adjacent pipes 16. A retaining ring 17 is fixedly connected to adjacent ends of multiple pipes 16. The retaining ring 17 is used to connect the upper and lower pipes 16. A rubber ring 7 is fixedly connected to the middle of the inner wall of the sleeve 3. The rubber ring 7 strengthens the connection between the pipes 16 and the retaining ring 17. For the purpose of interphase fit and stability, two strip grooves 4 are opened on the left and right sides of the inner wall of multiple sleeves 3. Trapezoidal blocks 6 are slidably connected to the inner wall of multiple strip grooves 4. Springs 5 ​​are fixedly connected to the opposite side of multiple trapezoidal blocks 6. Trapezoidal blocks 6 slide inside the strip grooves 4 under the action of springs 5. The opposite side of multiple springs 5 ​​is fixedly connected to the corresponding strip grooves 4. Springs 5 ​​act on trapezoidal blocks 6. The adjacent side of multiple trapezoidal blocks 6 is respectively fitted with the corresponding retaining rings 17. This structure enables adjacent pipes 16 to be interconnected and fixed to the top of the inner wall of the pile frame 1 through sleeves 3, trapezoidal blocks 6 and retaining rings 17.

[0033] Specifically, the structure mainly consists of a pile frame 1 and pipes 16. The pile frame 1 provides a stable foundation for the entire device. Multiple fixing sleeves 15 are fixed to the bottom of its inner wall. The pipes 16 on the lower side are connected to the corresponding fixing sleeves 15, which can quickly and initially position the pipes 16 and stabilize the position of the sonic logging tube. Sleeves 3 are set between the multiple pipes 16. The adjacent ends of the multiple pipes 16 are connected to retaining rings 17. There is a rubber ring 7 in the middle of the inner wall of the sleeve 3. Strip grooves 4 are opened on the left and right sides. Trapezoidal retaining blocks 6 are slidably connected in the grooves. The trapezoidal retaining blocks 6 are away from the center of the sleeve. A spring 5 is attached to one side, and the other end of the spring 5 is fixed to the strip groove 4. When the pipe 16 is installed, the ends of adjacent pipes 16 are close together, and the retaining ring 17 squeezes the trapezoidal retaining block 6. The trapezoidal retaining block 6 squeezes the spring 5 to slide in the strip groove 4 until it is in contact with the retaining ring 17. The rubber ring 7 enhances the stability of the internal structure of the sleeve 3 on the one hand, and makes the components fit more tightly on the other hand. This structure realizes rapid installation and tight fit of the pipe 16, ensuring the stability of the sonic logging tube during use and meeting the requirements of accurate measurement.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The protection mechanism 2 includes multiple connecting rods 201, which are fixedly connected to the top of the inner wall of the pile frame 1 to connect the pile frame 1 and the protection mechanism 2. A second fixing ring 207 is fixedly connected between adjacent connecting rods 201 to fix the connecting rods 201. A first fixing ring 202 is fixedly connected to adjacent ends of the multiple connecting rods 201 to fix the connecting rods 201. A rotating ring 203 is rotatably connected to the top of the inner wall of the first fixing ring 202, and multiple fixing rings are fixedly connected around the outer wall of the rotating ring 203. Rod 204, multiple fixed rods 204 are fixedly connected to multiple shielding covers 205 at opposite ends. Rotating the rotating ring 203 causes the fixed rods 204 to rotate, and the shielding covers 205 are also connected to the fixed rods 204 to rotate. The shielding covers 205 are used to shield the pipes 16 to prevent cement debris from entering. The outer walls of the multiple pipes 16 on the upper side are slidably connected to pipe sleeves 206. The middle of the outer wall of the multiple pipe sleeves 206 is fixedly connected to a strip ring 208. The strip ring 208 is fixedly connected to the pipe sleeve 206 and the connecting rod 201. This structure is used to stabilize the protection mechanism 2.

[0035] Specifically, multiple connecting rods 201 are fixed to the top of the inner wall of the pile frame 1, with adjacent connecting rods connected to fixed rings 207 and one end connected to fixed ring 202. The top of fixed ring 202 is rotatably connected to a rotating ring 203. Multiple fixed rods 204 are fixed around the rotating ring 203. The ends of fixed rods 204 are connected to shielding covers 205. The outer wall of the upper pipe 16 is fitted with a pipe sleeve 206. A strip ring 208 is connected to the middle of the pipe sleeve 206. The strip ring 208 is fixed to the pipe sleeve 206 and the connecting rods 201. When the device is working, if it is necessary to shield the top of the upper pipe 16, the rotating ring 203 is rotated, which drives the fixed rods 204 and shielding covers 205 to rotate, quickly aligning the shielding covers 205 with and covering the top of the upper pipe 16, blocking debris from entering and ensuring normal measurement data.

[0036] Reference Figure 1 , Figure 2 and Figure 3 Laser positioning devices 12 are fixedly connected to the outer walls of multiple pipe sleeves 206. The laser positioning devices 12 are perpendicular to the connecting rod 201 and are used to calibrate the verticality of the pipe 16 in real time. Multiple handles 9 are fixedly connected to the outer walls of the rotating ring 203. The outer walls of the handles 9 are all treated with anti-slip material. The handles 9 make it easier and less strenuous for operators to rotate the rotating ring 203. An indicator light 11 is fixedly connected to the top of the fixed ring 202. Multiple screws 10 are threaded to the four corners at the bottom of the indicator light 11. The bottoms of the screws 10 are threaded to the rotating ring 203. The indicator light 11 is used to detect whether the device mechanism is working properly.

[0037] Specifically, the outer wall of the sleeve 206 is connected to a laser positioning device 12, which is perpendicular to the connecting rod 201 and calibrates the verticality of the pipe 16 in real time. Multiple anti-slip handles 9 are connected around the rotating ring 203 to facilitate the operator's rotation. The top of the fixed ring 202 is connected to an indicator light 11, which is threaded to the rotating ring 203 with screws 10. The indicator light 11 shows whether the device is working properly.

[0038] Reference Figure 1 , Figure 2 and Figure 3 Rubber rings 8 are fixedly connected to the lower outer walls of multiple shielding covers 205. The multiple rubber rings 8 are respectively attached to the corresponding pipes 16, and the rubber rings 8 make the shielding cover 205 and the pipes 16 fit more tightly. A shielding net 14 is fixedly connected to the inner wall of the strip ring 208. The shielding net 14 is fixedly connected to the outer wall of the fixed ring 207. The shielding net 14 is used to prevent the operator from falling during operation. A reinforcing rib 13 is fixedly connected to the outer wall of multiple connecting rods 201. The top of the reinforcing rib 13 is attached to the bottom of the shielding net 14. The reinforcing rib 13 is used to strengthen the stability of the protection mechanism 2.

[0039] Specifically, multiple shielding covers 205 are connected to rubber rings 8 on the lower side of their outer walls. The rubber rings 8 fit with the corresponding pipes 16, making the shielding covers 205 and pipes 16 fit more tightly. The inner wall of the strip ring 208 is connected to a shielding net 14, which is also connected to the outer wall of the second fixed ring 207. During operation, the shielding net 14 can prevent operators from falling and ensure personnel safety.

[0040] Working principle: The pile frame 1 in the structure is the foundation structure of the pile foundation. During operation, multiple fixed sleeves 15 are fixedly connected to the bottom of the inner wall of the pile frame 1. Multiple pipes 16 on the lower side are fixedly connected to the corresponding fixed sleeves 15. The sleeve 3 is lowered from the multiple pipes 16 on the upper side. When the multiple pipes 16 are in contact with each other, they squeeze the rubber ring 7, which strengthens the stability of the contact between the pipes 16 and the retaining ring 17. The retaining ring 17 connecting the multiple pipes 16 between adjacent pipes squeezes the trapezoidal retaining block 6. The trapezoidal retaining block 6 squeezes the spring 5 at the opposite end and slides in the strip groove 4. When the multiple pipes 16 between adjacent pipes are tightly in contact, the compression on the trapezoidal retaining block 6 disappears. Under the action of the spring 5, the trapezoidal retaining block 6 slides to the adjacent side, thus contacting the retaining ring 17. This structure is fixed by the sleeve 3, the trapezoidal retaining block 6 and the retaining ring 17, which enhances the overall stability and integrity of the sonic logging pipe and prevents the sonic logging pipe from shifting or shaking during the pile foundation construction.

[0041] Furthermore, the protective mechanism 2 in the structure serves as the protective mechanism for the pile foundation. During operation, multiple connecting rods 201 are fixed to the top of the inner wall of the pile frame 1, acting as a fixed connection device. When the operator holds the handle 9 and rotates it, the fixed rod 204 is fixedly connected to the rotating ring 203, causing the fixed rod 204 to rotate. The fixed rod 204 is also fixedly connected to the cover 205, causing the cover 205 to rotate as well. When the cover 205 rotates to the top of the upper pipe 16, it is inserted downwards into the top of the pipe 16, making it fit tightly. Through the action of this mechanism, cement dust can be prevented from entering the pipe 16 during operation, affecting the test results and thus improving the test accuracy of the device.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
