Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for hoisting and placing acoustic pipes for diaphragm walls of plain ground. Background Art

[0002] An acoustic pipe is a tubular device used for ultrasonic detection in concrete structures. It evaluates the quality and integrity of concrete through the propagation characteristics of sound waves. Its working principle is based on the propagation characteristics of ultrasonic waves in a medium. When a transmitter sends ultrasonic waves and transmits them through the acoustic pipe, the sound waves will propagate inside the concrete. When encountering different media or internal defects, phenomena such as reflection, refraction, or attenuation will occur. The receiver captures these reflected sound wave signals and converts them into electrical signals. By analyzing these signals, the internal condition of the concrete, such as cracks, cavities, or other abnormalities, can be inferred.

[0003] Acoustic pipes are particularly important in the field of civil engineering. Especially during the construction of large building structures such as bridges, tunnels, and dams, they help engineers detect internal defects in concrete and ensure the safety and stability of the structure. In addition, in pile foundation testing, acoustic pipes can detect the integrity of the pile body and prevent potential safety hazards.

[0004] The Chinese utility model patent with the authorization announcement number CN210166348U discloses a structure for detecting the quality of diaphragm wall joints, including a diaphragm wall and a detector. Reinforcing cages are inserted and cast at the inner edges on both sides of the diaphragm wall. Acoustic pipes are inserted into the diaphragm wall inside the reinforcing cages. A connection seam is formed at the connection of the two diaphragm walls. A transmitting transducer is movably inserted into one acoustic pipe, and a receiving transducer is inserted into the adjacent acoustic pipe on the other side. The transmitting transducer and the receiving transducer are connected to the lower end of the detector. A flatness measuring instrument is clamped and connected to the diaphragm wall at the lower end of the detector. A horizontal measuring plate is driven and connected to the lower end of the flatness measuring instrument. A limiting hole is opened in the middle of the horizontal measuring plate. The lower end of the detector is inserted into the limiting hole. The beneficial effects are as follows: The quality detection is fast and convenient. The position of the defect can be predicted before excavation, problems occurring in the diaphragm wall can be prevented, and the safety of the diaphragm wall foundation pit construction is significantly improved.

[0005] In the initial departure and reception of existing shield tunnels in water-rich strata, a diaphragm wall of plain ground is generally used as a water-stop curtain. Since no reinforcing cage is set, it is difficult to lower the acoustic pipes for detecting the diaphragm wall of plain ground. On-site, the sonic transmission method is often abandoned for detecting the diaphragm wall of plain ground, resulting in poor detection effect of the diaphragm wall of plain ground.

[0029] Please refer to the appendix Figure 1-7 , a device for hoisting a sonic logging pipe for a diaphragm wall of plain ground, comprising a diaphragm wall guide wall 4 of plain ground. A guide wall embedded steel plate 5 is arranged inside the diaphragm wall guide wall 4 of plain ground close to the outer wall. Sonic logging pipe fixing members 3 are arranged on the outer walls of both sides of the diaphragm wall guide wall 4 of plain ground. The guide wall embedded steel plate 5 improves the construction efficiency and structural safety, making the cooperative connection between the sonic logging pipe fixing members 3 and the diaphragm wall guide wall 4 of plain ground more stable. A sonic logging pipe hoisting device 2 is fixedly installed between the plurality of sonic logging pipe fixing members 3. The sonic logging pipe hoisting device 2 is not easily detached through the plurality of sonic logging pipe fixing members 3. A sonic logging pipe 1 is installed inside the sonic logging pipe hoisting device 2.

[0030] The sonic logging pipe 1 comprises a sonic logging pipe body 11 and a sonic logging pipe joint expansion head 12. The sonic logging pipe body 11 is divided into a plurality of sonic logging pipe joints. A sonic logging pipe joint expansion head 12 is installed at each sonic logging pipe joint. The sonic logging pipe joint expansion head 12 has a three-lobe structure.

[0031] The sonic logging pipe hoisting device 2 comprises a hoisting device body 21 and hoisting device teeth 22. The hoisting device body 21 is divided into a plurality of hoisting device joints. The size of the hoisting device body 21 is larger than that of the sonic logging pipe body 11. Hoisting device teeth 22 are provided at each hoisting device joint. The inner side of the hoisting device teeth 22 has a three-lobe structure. The sonic logging pipe joint expansion head 12 corresponds to the hoisting device teeth 22 one by one and is dimensionally matched.

[0032] During use, since both the sonic logging pipe joint expansion head 12 and the hoisting device teeth 22 have a three-lobe structure, when the sonic logging pipe 1 is lowered, the sonic logging pipe joint expansion head 12 within the range of the hoisting device 2 does not overlap with the hoisting device teeth 22. When the sonic logging pipe 1 is fixed after being lowered, the sonic logging pipe joint expansion head 12 within the range of the hoisting device 2 overlaps with the hoisting device teeth 22. The above operations are repeatedly performed multiple times to gradually hoist a plurality of sonic logging pipe joints, solving the problems of anti-floating and deflection during the lowering of the sonic logging pipe, which has positive significance for promoting the detection of the diaphragm wall of plain ground by the sonic wave transmission method.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
