Description

Technical Field

[0001] This application relates to the field of sonic logging tube fixing technology, and in particular to a sonic logging tube fixing structure for pile foundation reinforcement cages. Background Technology

[0002] Bridge pile foundations, as the underground load-bearing core of a bridge structure, directly determine the safety and durability of the bridge. Ultrasonic testing is a key method for assessing the quality of pile foundations, and the acoustic logging tube is the propagation channel for ultrasonic waves. The quality of the bottom fixation of the acoustic logging tube, as the channel for sound wave propagation, directly affects the reliability of the test data.

[0003] For fixing the bottom of the sonic logging tube, existing technologies mainly use welding, binding, or steel reinforcement supports. However, manual welding can easily lead to burn-through of thin-walled tubes or weld beads on the inner wall, affecting the propagation of ultrasonic waves; binding fixation may loosen or fall under strong vibration environments. Furthermore, under complex geological conditions (such as karst areas and necked piles), traditional support fixation is susceptible to deformation, falling, and damage to the sonic logging tube due to concrete impact, resulting in distorted test data. Utility Model Content

[0004] To improve the installation quality and fixing reliability of sonic logging tubes, this application provides a sonic logging tube fixing structure for pile foundation reinforcement cages.

[0005] The sonic logging tube fixing structure for pile foundation reinforcement cages provided in this application adopts the following technical solution: A sonic logging tube fixing structure for a pile foundation reinforcement cage includes multiple connecting rods, each connecting rod having an mounting part and a welding part. The same end of the multiple connecting rods is connected to each other through the welding part. The welding part is used to connect with the extended main reinforcement of the reinforcement cage, and the mounting part is used for mounting the sonic logging tube. The inner diameter of the virtual ring formed by the multiple mounting parts is larger than the outer diameter of the sonic logging tube.

[0006] By adopting the above technical solution, before installing the sonic logging pipe, the welded part of the fixed structure is first connected to the extended main reinforcement of the steel cage. Then, the bottom of the sonic logging pipe is placed into a virtual ring formed by multiple connecting rods. A connection is established between the multiple connecting rods and the sonic logging pipe using a binding method. Since there are multiple connecting rods, multiple connection points can be established. Compared with existing technologies, no weld points are generated on the periphery of the sonic logging pipe. Furthermore, by using the fixed structure as a connection medium through multiple connection points, a stable and effective connection is established between the sonic logging pipe and the steel cage, thereby improving the installation quality and fixing reliability of the sonic logging pipe.

[0007] Optionally, the mounting part and the welding part are integrally formed.

[0008] By adopting the above technical solution, the overall strength and stability of the connecting rod can be improved, avoiding the problem of the sonic logging tube not being firmly fixed due to loose connection parts.

[0009] Optionally, there are at least four connecting rods, the number of which is even and symmetrically arranged; each connecting rod is integrally formed with its opposite connecting rod.

[0010] By adopting the above technical solution, the connecting rods can be evenly distributed around the sonic logging tube, which can better support and fix the sonic logging tube. At the same time, the overall strength and stability of the fixed structure are improved by the method of forming the connecting rods in pairs.

[0011] Optionally, the connecting rod is formed by bending a plain round steel bar.

[0012] By adopting the above technical solution, a fixed structure can be made from existing materials without the need for additional customization, thus reducing costs.

[0013] Optionally, it also includes an annular reinforcing member, the periphery of which is used for connection of the mounting parts, and multiple mounting parts are connected to the reinforcing member.

[0014] By adopting the above technical solution, fasteners are used to further establish connections between multiple mounting parts, thereby improving the structural strength and stability of the fixed structure.

[0015] Optionally, the reinforcement is connected to the end of the mounting portion away from the welding portion.

[0016] Optionally, multiple reinforcement components are provided, and the multiple reinforcement components are arranged at intervals along the length direction of the mounting portion.

[0017] By adopting the above technical solutions, the structural strength and stability of the fixed structure can be further improved.

[0018] Optionally, the reinforcing member is welded and fixed to the mounting part.

[0019] By adopting the above technical solution, the reinforcement component and the mounting part are welded together, resulting in a high and stable connection strength.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. A fixed structure is formed by multiple connecting rods. The welded part of the connecting rod is used to weld and fix it to the extended main bar of the steel cage, and the installation part of the connecting rod is used to connect the sonic logging tube. Thus, the fixed structure serves as a connection medium to establish an effective and stable connection between the bottom of the sonic logging tube and the steel cage, thereby improving the installation quality and fixing reliability of the sonic logging tube. 2. The fixing structure includes a reinforcing ring. The ends of the multiple connecting rods that are away from the welding part are welded and fixed to the reinforcing ring, thereby increasing the connection stability between the multiple connecting rods and further improving the installation stability of the sonic logging tube.

[0024] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0025] This application discloses a sonic logging tube fixing structure for a pile foundation reinforcement cage.

[0026] Reference Figure 1 and Figure 2 The fixing structure for the sonic logging tube 3 used in the pile foundation reinforcement cage 4 includes multiple connecting rods 1 and annular reinforcing members 2. Each connecting rod 1 includes an mounting part 11 and a welding part 12, with the same end of the multiple connecting rods 1 interconnected via the welding part 12. The inner diameter of the virtual ring formed by the multiple connecting rods 1 is larger than the outer diameter of the sonic logging tube 3. The welding part 12 connects to the extended main reinforcement of the reinforcement cage 4, and the mounting part 11 is used for installing the sonic logging tube 3.

[0027] In this embodiment, the mounting part 11 and the welding part 12 are integrally formed. Four connecting rods 1 are provided and symmetrically arranged, with two opposite connecting rods 1 integrally formed. In this embodiment, the two opposite connecting rods 1 are formed by bending a single plain round steel bar. Plain round steel bars have good flexibility and strength, making them easy to process into the required shape. Besides plain round steel bars, other metal rods with certain flexibility and strength can also be used, such as ribbed steel bars.

[0028] In other embodiments, the number of connecting rods 1 can also be an even number, such as six or eight. In other embodiments, the number of connecting rods 1 can also be an odd number, in which case the same section of multiple connecting rods 1 can be fixedly connected by welding, forging, or other methods.

[0029] The periphery of the reinforcing member 2 is used for connection to the mounting portion 11, and the ends of the plurality of mounting portions 11 away from the welding portion 12 are all connected to the periphery of the reinforcing member 2. It is understood that in other embodiments, the connection point between the mounting portion 11 and the reinforcing member 2 may also be at the middle position of the mounting portion 11. In this embodiment, the reinforcing member 2 is also formed by bending a plain round steel bar.

[0030] The connection between the reinforcement 2 and the mounting part 11 can be achieved by welding, bolting, or other methods. Welding can make the reinforcement 2 and the mounting part 11 form a whole, improving the stability of the structure; bolting facilitates disassembly and replacement.

[0031] In this embodiment, one reinforcement member 2 is provided. In other embodiments, multiple reinforcement members 2 may be provided, in which case the multiple reinforcement members 2 are arranged at intervals along the length direction of the mounting portion 11.

[0032] The implementation principle of the sonic logging tube 3 fixing structure for pile foundation reinforcement cage in the embodiment is as follows: When making the fixing structure, first cut the plain round steel bars of appropriate length according to the diameter and fixing spacing of the sonic logging tube 3; then use a steel bar bending machine to bend the steel bars into a U-shape, that is, to form two connecting rods 1, and at the same time bend them to form a ring-shaped reinforcement 2.

[0033] Next, the fabricated fixing structure is welded to the position in the reinforcing cage 4 where the bottom of the sonic logging tube 3 will be installed. Then, the bottom of the sonic logging tube 3 is placed into the virtual ring formed by the annular reinforcing member 2 and multiple connecting rods 1, ensuring that the sonic logging tube 3 is parallel and perpendicular to the reinforcing cage 4 during the placement process. Finally, the sonic logging tube 3 is tied to the connecting rods 1 and the reinforcing member 2 with wire to complete the installation of the sonic logging tube 3.

[0034] The above scheme uses a fixed structure as a connecting medium to establish a multi-point uniform stress structure between the sonic logging pipe 3 and the reinforcing cage 4. This avoids stress concentration caused by single-point fixing and effectively prevents the sonic logging pipe 3 from shifting, falling, or bending during the transportation, lowering, and concrete construction of the reinforcing cage 4. Simultaneously, the cage-like shape at the bottom of the fixed structure protects the bottom of the sonic logging pipe 3, ensuring its structural integrity and solving the problem of damage and falling to the bottom of the sonic logging pipe 3 caused by traditional open-bottom structures. This ensures the requirements for full-length impact quality testing.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
