[0003] A kind of acoustic measuring pipe is disclosed in Chinese patent with announcement number CN209412881U, and its technical scheme points are that at least two sections of pipe body are connected to constitute, two sections of pipe body are first pipe body and second pipe body with same pipe diameter, adjacent first pipe body and second pipe body are sealed and connected by pipe joint, and outer end is sealed by sealing cover, pipe joint includes: inner sleeve, first outer sleeve and second outer sleeve.Technical effect is that first pipe body and second pipe body can be butt-jointed by pipe joint, without changing the structure of pipe body, using pipe joint avoids the phenomenon of slurry leakage and pipe blockage, pipe joint is connected by screw thread, manual rotation when butting, construction installation is very convenient, reduces the time of field installation.

[0004] The end of the acoustic measuring pipe is sealed by the sealing cover, and in actual construction, since the concrete is not smooth, the sealing cover can be pierced when the pipe body is buried, so that the sealing environment of the whole acoustic measuring pipe is damaged, and the detection result of the pile is affected. UTILITY MODEL CONTENT

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a plastic alloy acoustic measuring pipe, to enhance the bottom structure of the acoustic measuring pipe, reduce the phenomenon of internal sealing damage of the acoustic measuring pipe, and improve the detection accuracy of the pile.

[0006] The above technical purpose of the utility model is realized by the following technical scheme:

[0007] A plastic alloy acoustic measuring pipe comprises a plurality of groups of first pipe bodies and second pipe bodies connected adjacent to each other by pipe joints, the end of the first pipe body away from the pipe joint at the bottom end of the embedding direction is connected with a bottom sealing cover, the end of the second pipe body away from the pipe joint at the top end of the embedding direction is connected with a top sealing cover, the end of the first pipe body close to the bottom sealing cover is provided with a reinforcing cover, the reinforcing cover comprises an extension pipe abutting against the inner wall of the first pipe body, a flange fixedly connected to the end of the extension pipe and abutting against the flat surface of the pipe wall of the first pipe body, and a sealing cover fixedly connected to the inner wall of the extension pipe.

[0008] The above technical solution involves installing a reinforcing cap at the end of the first pipe body near the bottom seal during installation. The flange and sealing cap together create a seal at the bottom of the first pipe body, thereby strengthening the internal seal of the sonic logging pipe. If the bottom seal breaks during installation, the reinforcing cap can also provide sealing protection for the sonic logging pipe, enhancing the bottom structure of the sonic logging pipe, reducing the risk of damage to the internal seal, and improving the accuracy of pile detection.

[0009] Furthermore, a buffer cavity is formed between the end face of the flange away from the pipe joint and the end face of the sealing cap away from the pipe joint, recessed towards the pipe joint.

[0010] Through the above technical solution, when the bottom cover is punctured by concrete or other foreign objects, the buffer cavity buffers the damage to the bottom cover, improves the sealing tightness of the reinforcing cover, and reduces the damage to the reinforcing cover after the bottom cover is damaged.

[0011] Furthermore, several reinforcing ribs connected to the sealing cap and the flange are provided inside the buffer cavity.

[0012] The above technical solution increases the overall structural strength of the reinforcing cover by reinforcing ribs, making the sealing of the first pipe body by the reinforcing cover more tight and reliable.

[0013] Furthermore, the end face of the reinforcing rib on the side away from the pipe joint is flush with the end face of the flange on the side away from the pipe joint.

[0014] By using the above technical solution, the flange is set flush with the flange, so that the entire end face has higher stress continuity while having strong structural strength, and reduces the deformation caused by the cross-sectional wind force compression caused by the stepped surface.

[0015] Furthermore, the end face of the bottom cover is set as a curved surface, and transitions in an arc away from the first tube body in the direction of the first tube body axis.

[0016] By using the above technical solution, the bottom cover is made curved, which makes it easier to reduce resistance when the sonic logging pipe is pre-embedded, and also makes it easier to guide and peel away concrete or other foreign objects, reducing the damage caused by the squeezing between concrete or other foreign objects and the bottom cover.

[0017] Furthermore, the bottom cover is provided with several reinforcing ribs.

[0018] The above technical solution uses reinforcing ribs to improve the structural strength of the bottom cover and reduce damage to the bottom cover.

[0019] Furthermore, the pipe fitting includes a first outer sleeve fitted onto the end of the first pipe body away from the bottom cap, an inner sleeve passing through the first outer sleeve and connected to the second pipe body, and a second outer sleeve fitted onto the inner sleeve and threadedly engaged with the first outer sleeve. The first outer sleeve has an external thread section, and the second outer sleeve has an internal thread section that engages with the external thread section. A dust cover covering the cavity of the first pipe body is connected to the external thread section.

[0020] The above technical solution connects the first pipe body and the second pipe body by connecting the first outer sleeve, the inner sleeve, and the second outer sleeve. This allows for adjustments to the length of the first pipe body and the second pipe body, or the addition of the number of the first pipe body and the second pipe body, according to actual construction needs.

[0021] Furthermore, the dust cover facilitates temporary sealing of the first pipe body during transportation, packaging, and construction, reducing the occurrence of concrete or other impurities falling into the sonic logging pipe.

[0022] Furthermore, the dust cover has several snap-fit ​​protrusions inside that correspond to the external thread section.

[0023] The above technical solution enables a quick connection between the dust cover and the first outer sleeve through the snap-fit ​​protrusions inside the dust cover.

[0024] Furthermore, the end of the inner sleeve away from the top cover is fitted with a limiting sleeve that is threadedly engaged with the internal thread section.

[0025] Furthermore, the limiting sleeve includes a connecting pipe sleeved on the outer wall of the inner sleeve, a limiting ring fixedly connected to the end of the connecting pipe away from the second pipe body and abutting against the inner sleeve wall plane, and a connecting external thread fixedly connected to the outer wall of the connecting pipe and cooperating with the internal thread section.

[0026] The above technical solution reduces the impact damage to the inner sleeve during transportation by using the limiting sleeve, and facilitates the positioning and locking of the second outer sleeve at one end of the second tube body, thereby facilitating a quick connection between the second outer sleeve and the first outer sleeve during construction.

[0027] In summary, this utility model has the following beneficial effects:

[0028] By reinforcing the cover, the sealing of the entire sonic logging tube is further strengthened and protected, the bottom structure of the sonic logging tube is enhanced, the phenomenon of internal seal damage to the sonic logging tube is reduced, and the accuracy of pile detection is improved.

[0029] The connection between the first and second pipe bodies is achieved through pipe fittings, which facilitates the adjustment of the length of the sonic logging pipe according to construction needs, thus meeting construction requirements. Furthermore, the dust cover and limiting sleeve reduce the impact of concrete or foreign objects falling into the sonic logging pipe on the test results, and facilitate efficient installation of the sonic logging pipe.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] A type of plastic alloy acoustic logging tube, such as Figure 1 As shown, the system includes several hollow cylindrical first pipe bodies 1 and second pipe bodies 2, with pipe joints 3 connecting adjacent first pipe bodies 1 and second pipe bodies 2. By connecting the first pipe bodies 1 and second pipe bodies 2 through the pipe joints 3, the length of the sonic logging pipes can be spliced ​​according to construction requirements, which facilitates production, transportation and installation.

[0041] The diameters of the first pipe body 1 and the second pipe body 2 can be the same. It can be understood that the first pipe body 1 and the second pipe body 2 refer to two pipe bodies connected on both sides of the pipe joint 3. In this embodiment, the pipe body located at the bottom end in the burial direction is the first pipe body 1, and the pipe body located at the top end in the burial direction is the second pipe body 2. Therefore, several pipe bodies located at the non-end of the sonic logging pipe can be either the first pipe body 1 or the second pipe body 2, with the corresponding pipe joint 3 used to distinguish the two connected pipe bodies.

[0042] The first pipe body 1 located at the bottom end of the burial direction is connected to a bottom cover 4. The bottom cover 4 is located at the end of the first pipe body 1 away from the pipe joint 3. The bottom cover 4 is connected to the outer wall of the first pipe body 1 by an interference fit.

[0043] like Figure 2 As shown, the end face of the bottom cover 4 is curved and transitions in an arc away from the axis of the first tube 1. Furthermore, the bottom cover 4 contains several reinforcing ribs 12.

[0044] The bottom cover 4 is designed as a curved surface to reduce resistance during the pre-embedding of the sonic logging pipe and to facilitate the diversion and removal of concrete or other foreign objects, thus reducing damage caused by compression between the concrete or other foreign objects and the bottom cover 4. The reinforcing rib 12 is used to improve the structural strength of the bottom cover 4 and reduce damage to the bottom cover 4.

[0045] like Figure 1 As shown, a top cover 5 is connected to the second pipe body 2 located at the top of the burial direction. The top cover 5 is located at the end away from the pipe joint 3. The top cover 5 is detachably connected to the top of the second pipe body 2. The connection method can be interference fit, adhesive, etc.

[0046] The bottom cover 4, several first pipe bodies 1 and second pipe bodies 2 connected by pipe joints 3, and the top cover 5 form a sealed pipe structure, which facilitates the vacuuming of the pipe body when the sonic logging pipe is working. At the same time, the top cover 5, which is detachably connected to the end of the second pipe body 2 located at the top of the burial direction, meets the requirements for multiple operations inside the pipe body.

[0047] like Figure 2 and Figure 3 As shown, in order to reduce the phenomenon of damage to the sealing structure inside the pipe caused by the bottom end of the sonic logging pipe being broken during installation, a reinforcing cover 6 is provided at the end of the first pipe body 1 near the bottom cover 4.

[0048] The reinforcing cover 6 includes an extension tube 7 that abuts against the inner wall of the first tube body 1, a flange 8 that is fixedly connected to the end of the extension tube 7 and abuts against the wall plane of the first tube body 1, and a sealing cover 9 that is fixedly connected to the inner wall of the extension tube 7.

[0049] A reinforcing cap 6 is installed at the end of the first pipe body 1 near the bottom seal 4 during installation. The flange 8 and the sealing cap 9 together seal the bottom of the first pipe body 1, thus strengthening the internal seal of the sonic logging pipe. If the bottom seal 4 cracks during installation, the reinforcing cap 6 can also provide sealing protection for the sonic logging pipe, enhancing the bottom structure of the pipe, reducing the likelihood of internal seal damage, and improving the accuracy of pile detection.

[0050] A buffer cavity 10 is formed between the end face of the flange 8 away from the pipe joint 3 and the end face of the sealing cap 9 away from the pipe joint 3, recessed towards the pipe joint 3. Several reinforcing ribs 11 are provided in the buffer cavity 10, connecting the sealing cap 9 and the flange 8.

[0051] When the bottom cover 4 is punctured by concrete or other foreign objects, the buffer cavity 10 cushions the damage to the bottom cover 4, improving the sealing tightness of the reinforcing cover 6 and reducing the damage to the reinforcing cover 6 after the bottom cover 4 is damaged. The reinforcing ribs 11 increase the overall structural strength of the reinforcing cover 6, making the sealing of the first pipe body 1 by the reinforcing cover 6 more tight and reliable.

[0052] The end face of the reinforcing rib 11 away from the pipe joint 3 is flush with the end face of the flange 8 away from the pipe joint 3. Setting the flange 8 flush with the end face makes the entire end face have higher stress continuity while having strong structural strength, and reduces the deformation caused by the cross-sectional wind force compression caused by the stepped surface.

[0053] like Figure 4 As shown, the pipe fitting 3 includes a first outer sleeve 13 sleeved on the end of the first pipe body 1 away from the bottom cap 4, an inner sleeve 14 passing through the first outer sleeve 13 and connected to the second pipe body 2, and a second outer sleeve 15 sleeved on the inner sleeve 14 and threadedly engaged with the first outer sleeve 13. The first outer sleeve 13 has an external thread section 16, and the second outer sleeve 15 has an internal thread section 17 that engages with the external thread section 16.

[0054] The first outer sleeve 13 is fixedly connected to the end of the first tube body 1, which can be glued. The second outer sleeve 15 can slide along the axis of the second tube body 2 and can rotate relative to the second tube body 2. The inner sleeve 14 can be fixedly connected to the end of the second tube body 2, which can be glued. The inner sleeve 14 has a stepped surface, which limits the second outer sleeve 15 fitted outside the second tube body 2, thereby preventing the second outer sleeve 15 from detaching from the second tube body 2.

[0055] When the second outer sleeve 15 is threadedly connected to the first outer sleeve 13, the adjacent first tube body 1 and second tube body 2 are connected and fixed, and the inner sleeve 14 achieves a seal at the connection between the first tube body 1 and the second tube body 2.

[0056] The sonic logging tube is located in the pipe body at a position other than the two ends. The bottom end of the same pipe body in the burial direction is provided with a second outer sleeve 15, while the top end is provided with a first outer sleeve 13.

[0057] like Figure 5 and Figure 6 As shown, when the external thread section 16 is not threadedly engaged with the internal thread section 17, a dust cover 18 covering the cavity of the first pipe body 1 is connected to the external thread section 16. The dust cover 18 has several snap-fit ​​protrusions 19 corresponding to the external thread section 16 inside.

[0058] The snap-fit ​​protrusion 19 can be a threaded section or protrusion that is set on the inner wall of the dust cover 18 and can be embedded in the groove of the external thread section 16. The dust cover 18 is made of an elastic material, such as plastic, so the snap-fit ​​fixation between the dust cover 18 and the first outer sleeve 13 can be achieved through its own elasticity.

[0059] The dust cover 18 and the first outer sleeve 13 are quickly connected by the snap-fit ​​protrusion 19 inside the dust cover 18. The dust cover 18 is placed over the opening of the first tube 1 to facilitate temporary sealing of the first tube 1 during transportation, packaging and construction, reducing the occurrence of concrete or other impurities falling into the sonic logging tube.

[0060] like Figure 7 and Figure 8 As shown, the end of the inner sleeve 14 away from the top cover 5 is fitted with a limiting sleeve 20 that is threadedly engaged with the internal thread section 17.

[0061] The limiting sleeve 20 includes a connecting pipe 21 sleeved on the outer wall of the inner sleeve 14, a limiting ring 22 fixedly connected to the end of the connecting pipe 21 away from the second pipe body 2 and abutting against the wall plane of the inner sleeve 14, and a connecting external thread 23 fixedly connected to the outer wall of the connecting pipe 21 and mating with the internal thread section 17. The connecting external thread 23 can be a continuous thread end or an intermittent thread section.

[0062] The limiting sleeve 20 reduces the impact damage to the inner sleeve 14 during transportation and facilitates the positioning and locking of the second outer sleeve 15 at one end of the second tube body 2, thereby facilitating a quick connection between it and the first outer sleeve 13 during construction.

[0063] The dust cover 18 and the limiting sleeve 20 can be used temporarily during transportation and installation, and must be removed when the acoustic logging tube is finally installed.

[0064] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
