Description

Technical Field

[0001] This application relates to the field of foundation pile construction, and in particular to a foundation pile acoustic logging system. Background Technology

[0002] In engineering practice, using metal acoustic logging tubes as ultrasonic testing channels for concrete cast-in-place piles to test the integrity of the piles is a mature and stable construction technique in the current infrastructure field. The acoustic logging tubes are arranged vertically along the entire length of the pile foundation reinforcement cage, and the number of acoustic logging tubes is evenly distributed according to the pile diameter. The acoustic logging tubes are independent of each other. After the concrete is poured to form the pile, a water pipe is inserted into the bottom of the acoustic logging tube to change the water. After the test, the acoustic logging tube is filled with cement slurry and sealed in the same way.

[0003] When sonic logging tubes are installed on the reinforcing cage, they are arranged independently and longitudinally inside the cage. Insufficient constraint at the ends of the cage makes the tubes prone to bending, deformation, and displacement. This is particularly common at the lower auxiliary cage section of long friction piles, leading to abnormal or incomplete ultrasonic testing data at the pile bottom. Furthermore, water needs to be added individually to each tube as the ultrasonic testing coupling medium to prevent pressure differences between the inside and outside of the tube, which could cause deformation. The water level changes in each tube are observed to determine if there are any abnormalities such as disconnection, leakage, or blockage. This process is labor-intensive, and installation abnormalities are often overlooked by technicians. After the concrete has set, workers use rigid plastic water pipes inserted into the bottom of each tube to pressurize and inject water until all rust, sludge, and other impurities are flushed away and replaced with clean water. The sonic logging tubes, unobstructed and filled with clean water coupling medium, serve as the vertical channel for ultrasonic testing of the pile foundation. The number of rigid plastic pipes increases with the pile length, increasing the workload and time required for workers. Utility Model Content

[0004] The purpose of this application is to address the problems mentioned in the background art, such as the tendency of sonic logging pipes to bend, deform, and shift, the large workload of adding water to each sonic logging pipe individually as a coupling medium for ultrasonic testing, and the large workload of workers inserting rigid plastic water pipes into the bottom of each sonic logging pipe for pressurized water injection and cleaning. This application provides a sonic logging pipe system for foundation piles.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A pile sonic logging system includes an annular sonic logging tube, on which several circumferentially distributed tee connectors are fixed, and vertical sonic logging tubes are fixed on the tee connectors. Several auxiliary reinforcement mechanisms are provided on the annular sonic logging tube.

[0007] By adopting the above technical solution, the annular sonic logging tube, the vertical sonic logging tube, and the reinforcing cage are tied together with steel wire. Then, the annular sonic logging tube is connected using an auxiliary reinforcement mechanism, and then fixed to the bottom of the reinforcing cage using the auxiliary reinforcement mechanism. This allows for timely detection of abnormalities in the sonic logging tube system, timely cage lifting and correction, and convenient removal of debris from the annular and vertical sonic logging tubes. At the same time, it improves the stability of the connection between the annular sonic logging tube and the reinforcing cage and reduces the possibility of displacement and deformation between the annular sonic logging tube and the reinforcing cage.

[0008] Furthermore, the auxiliary reinforcement mechanism includes a reinforcement block, a connecting component is provided between the reinforcement block and the annular acoustic tube, a reinforcement plate is provided on the reinforcement block, and a limit head is fixed at one end of the reinforcement plate.

[0009] By adopting the above technical solution, the connecting components on the reinforcing block are connected to the annular sonic logging tube, and then the reinforcing plate and limiting buckle on the reinforcing block are fastened to the steel cage, thereby improving the stability of the connection between the annular sonic logging tube and the steel cage and reducing the possibility of misalignment between the annular sonic logging tube and the steel cage.

[0010] Furthermore, a movable threaded rod is threadedly connected to the reinforcing block, and the movable threaded rod penetrates the reinforcing block.

[0011] By adopting the above technical solution, the movable threaded rod moves on the reinforcing block, and the movable threaded rod drives the reinforcing plate to move, thereby making it easy for the reinforcing plate and the limiting head to be fastened to the steel cage.

[0012] Furthermore, the connecting assembly includes a fixing buckle one fixed to the reinforcing block, and a fixing buckle two rotatably connected to the fixing buckle one.

[0013] By adopting the above technical solution, fixing buckle one and fixing buckle two can be fastened to the annular sonic logging pipe, thereby making it easy to fix the reinforcing block to the annular sonic logging pipe.

[0014] Furthermore, both the first and second fixing buckles have two symmetrical fixing holes.

[0015] By adopting the above technical solution, after the first and second fixing buckles are fastened together, the first and second fixing buckles are fixed by passing a steel wire through the fixing hole, which makes it easy to fix the first and second fixing buckles together.

[0016] In summary, this application includes at least one of the following beneficial effects;

[0017] 1. This application utilizes a method where, during the installation of vertical sonic logging pipes section by section, one pipe is filled with clean water. Due to the principle of communicating vessels, the water head pressure and water level are the same in all vertical sonic logging pipes. If the water level does not drop, it indicates that the sealing of the installed sections of sonic logging pipes meets the requirements. If the water level drops due to leakage in a vertical sonic logging pipe, it indicates an abnormality in the installation of the previous section. This allows for timely detection of installation abnormalities and prompt reinstallation of the sonic logging pipes. After the concrete has set, there is no need to insert the water pipe into the bottom of the sonic logging pipes. Instead, the water pipe is connected to one of the sonic logging pipe openings for water injection. Under the interconnected effect of the annular sonic logging pipes at the pile bottom, rust and sludge are discharged from the other sonic logging pipes and replaced with clean water for ultrasonic testing. For impurities that are difficult to remove, multiple inlets and one outlet, or one inlet and one outlet with the other outlets closed, can be used to conveniently discharge debris from the annular and vertical sonic logging pipes. After the ultrasonic testing of the pile foundation is completed, there is no need to insert the grouting pipe into the bottom of the sonic logging pipe. Instead, the grouting machine is connected to the opening of one or more sonic logging pipes. With the bottom of the pipes connected, cement grout is injected into the pipe opening and clean water is discharged from the other sonic logging pipe openings. After the clean water is drained, the grouting and sealing of the sonic logging pipe is completed, reducing the possibility of rust in the sonic logging pipe system.

[0018] 2. In this application, when using the pile sonic logging system, the annular sonic logging tube is first assembled, and several T-joints are fixed on the annular sonic logging tube. Then, a vertical sonic logging tube is fixed on the T-joints. The annular sonic logging tube, the vertical sonic logging tube and the reinforcing cage are tied together with steel wire. Fixing buckles one and two are fastened to the annular sonic logging tube. Then, the moving threaded rod is rotated, and the moving threaded rod moves on the reinforcing block. The moving threaded rod drives the reinforcing plate, and the reinforcing plate drives the limiting head, so that the reinforcing plate and the limiting buckle are fastened to the reinforcing cage from the outside of the reinforcing cage. The reinforcing plate and the limiting head are fastened to the reinforcing cage, and the annular sonic logging tube and the reinforcing cage are further fixed together. Then, the annular sonic logging tube and the vertical sonic logging tube are entered into the pile hole along with the reinforcing cage. This can improve the stability of the connection between the annular sonic logging tube and the reinforcing cage and reduce the displacement deformation between the annular sonic logging tube and the reinforcing cage.

[0019] 3. In this application, after the first and second fixing buckles are fastened together, a steel wire is used to pass through the fixing hole to fix the first and second fixing buckles, thereby achieving the purpose of easily fixing the first and second fixing buckles together.

[0025] The following is in conjunction with the appendix Figure 1 —3 provides further detailed description of this application.

[0026] This application discloses a pile acoustic logging system.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A pile sonic logging system includes an annular sonic logging pipe 1, a plurality of circumferentially distributed tee connectors 3 fixed on the annular sonic logging pipe 1, a vertical sonic logging pipe 2 fixed on the tee connectors 3, and a plurality of auxiliary reinforcement mechanisms 4 provided on the annular sonic logging pipe 1.

[0028] When using this pile sonic logging system, first assemble the annular sonic logging tube 1 and fix several T-connectors 3 on the annular sonic logging tube 1. Then fix the vertical sonic logging tube 2 on the T-connectors 3. Use steel wire to tie the annular sonic logging tube 1, the vertical sonic logging tube 2 and the reinforcing cage together. Then use the auxiliary reinforcement mechanism 4 to connect the annular sonic logging tube 1. Then use the auxiliary reinforcement mechanism 4 to fix and connect to the bottom of the reinforcing cage. The auxiliary reinforcement mechanism 4 increases the stability of the connection between the reinforcing cage and the annular sonic logging tube 1, which can improve the stability of the connection between the annular sonic logging tube and the reinforcing cage and reduce the displacement deformation between the annular sonic logging tube and the reinforcing cage. The annular sonic logging tube 1 and the vertical sonic logging tube 2 are lowered into the pile pit along with the reinforcing cage. During the installation of the vertical sonic logging tube 2 section by section, one of the tubes is filled with clean water. Due to the principle of communicating vessels, the water head pressure and water level are the same in all vertical sonic logging tubes 2. If the clean water level does not drop, it indicates that the sealing of the installed section of sonic logging tube meets the requirements. If the vertical sonic logging tube 2 leaks or the water level drops, it indicates that there is an abnormality in the installation of the previous section of sonic logging tube. If the problem is found in time, the cage can be lifted and the sonic logging tubes can be reinstalled until the requirements are met. Then, the remaining vertical sonic logging tubes 2 are installed, and the water pipe is connected to one of the exposed vertical sonic logging tube 2 openings. Connect the pipes and inject clean water from top to bottom into the sonic logging pipes. With the connection at the bottom of the pile, impurities such as rust and sludge in the hole are discharged through other vertical sonic logging pipes 2 and replaced with clean water for ultrasonic testing. For impurities that are difficult to remove, multiple pipes can be used for water inlet and one pipe for water outlet, or one pipe for water inlet and one pipe for water outlet with the other pipes closed. Pressurization can be used to remove blockages in the pipes, making it easier to remove debris from the annular and vertical sonic logging pipes. After the annular sonic logging pipe 1 and the vertical sonic logging pipe 2 are used up, grout is injected into the vertical sonic logging pipe 2 and the annular sonic logging pipe 1 to reduce the possibility of corrosion and damage to the annular sonic logging pipe 1 and the vertical sonic logging pipe 2.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The auxiliary reinforcement mechanism 4 includes a reinforcement block 41, a connecting component 45 is provided between the reinforcement block 41 and the annular acoustic tube 1, a reinforcement plate 42 is provided on the reinforcement block 41, and a limit head 43 is fixed at one end of the reinforcement plate 42.

[0030] In addition, a movable threaded rod 44 is threadedly connected to the reinforcing block 41, and the movable threaded rod 44 passes through the reinforcing block 41.

[0031] Furthermore, the connecting component 45 includes a fixing buckle 451 fixed to the reinforcing block 41, and a fixing buckle 452 rotatably connected to the fixing buckle 451.

[0032] Furthermore, both the first fixing buckle 451 and the second fixing buckle 452 have two symmetrical fixing holes 453.

[0033] After the annular sonic logging tube 1, the vertical sonic logging tube 2, and the reinforcing cage are tied together with steel wire, fixing buckles 1 (451) and 2 (452) are fastened onto the annular sonic logging tube 1. Then, steel wire is passed through the fixing holes 453 on fixing buckles 1 (451) and 2 (452) to fix them together. Then, the movable threaded rod 44 is rotated to move on the reinforcing block 41, which in turn moves the reinforcing plate. 42. The reinforcing plate 42 drives the limiting head 43, allowing the reinforcing plate 42 and the limiting buckle to be fastened to the reinforcing cage from the outside. The reinforcing plate 42 and the limiting head 43 are fastened to the reinforcing cage, further fixing the annular sonic logging tube 1 to the reinforcing cage. By using the reinforcing plate 42 and the limiting head 43 fixed on the annular sonic logging tube 1 to be fastened to the reinforcing cage, the stability of the connection between the annular sonic logging tube 1 and the reinforcing cage can be improved, and the possibility of displacement and deformation between the annular sonic logging tube 1 and the reinforcing cage can be reduced.

[0034] Working principle: When using this pile sonic logging system, first assemble the annular sonic logging tube 1, and fix several T-connectors 3 on the annular sonic logging tube 1. Then fix the vertical sonic logging tube 2 on the T-connectors 3. Use steel wire to tie the annular sonic logging tube 1, the vertical sonic logging tube 2 and the reinforcing cage together, so that fixing buckle one 451 and fixing buckle two 452 are fastened on the annular sonic logging tube 1. Then use steel wire to pass through the fixing holes 453 on fixing buckle one 451 and fixing buckle two 452, and use steel wire to... Fix the first fixing buckle 451 and the second fixing buckle 452 together, then rotate the movable threaded rod 44 to move it on the reinforcing block 41. The movable threaded rod 44 drives the reinforcing plate 42, which in turn drives the limiting head 43, allowing the reinforcing plate 42 and the limiting buckle to fasten onto the reinforcing cage from the outside. This further secures the annular sonic logging tube 1 to the reinforcing cage. Then, the annular sonic logging tube 1 and the vertical sonic logging tube 2 move with the reinforcing cage. During the installation of the vertical sonic logging pipes 2 section by section into the foundation pile pit, one pipe is filled with clean water. Due to the principle of communicating vessels, the water head pressure and water level are the same in all vertical sonic logging pipes 2. If the water level does not drop, it indicates that the sealing of the installed sections of sonic logging pipes meets the requirements. If the vertical sonic logging pipe 2 leaks and the water level drops, it indicates an abnormality in the installation of the previous section of sonic logging pipe. If the problem is detected in time, the cage can be lifted and the sonic logging pipe reinstalled until the requirements are met. Then, the remaining vertical sonic logging pipes 2 are installed, and the water pipes are connected to them... One of the external vertical sonic logging pipes 2 is connected to the pipe. Clean water is injected into the pipe from top to bottom. With the connection at the bottom of the pile, impurities such as rust and sludge in the hole are discharged through other vertical sonic logging pipes 2 and replaced with clean water for ultrasonic testing. For impurities that are difficult to remove, multiple pipes can be used for water inlet and one pipe for water outlet, or one pipe for water inlet and one pipe for water outlet with the other pipes closed. The pressure is increased to remove the blockage in the pipe. After the annular sonic logging pipe 1 and the vertical sonic logging pipe 2 are used up, grout is injected into the vertical sonic logging pipe 2 and the annular sonic logging pipe 1.
