Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic detection products for cast-in-place piles, in particular to a plastic alloy ultrasonic detection tube. Background Art

[0002] The ultrasonic detection tube is made of plastic alloy and is pre-buried in the pile. It is the channel for the probe to enter the pile body when the ultrasonic detection method is used for cast-in-place piles. It is an important component of the ultrasonic detection system for cast-in-place piles. The quality of the pile can be detected using the ultrasonic detection tube.

[0003] For example, a Chinese patent with the announcement number CN209412881U discloses an acoustic detection pipe, the technical solution of which is mainly composed of at least two sections of pipe bodies connected together, the two sections of pipe bodies are the first pipe body and the second pipe body with the same pipe diameter, the adjacent first pipe body and the second pipe body are sealed and connected by a pipe joint, and the outer end is sealed by a sealing cover, and the pipe joint includes: an inner sleeve, a first outer sleeve and a second outer sleeve. The technical effect is that the first pipe body and the second pipe body can be docked by using the pipe joint without changing the structure of the pipe body, and the phenomenon of leakage and pipe blockage can be avoided after docking by using the pipe joint. The pipe joint adopts a threaded connection, and when docking, it is manually rotated, which is very convenient for construction and installation, reducing the time of on-site installation.

[0004] The ends of the acoustic detection tube are sealed by sealing covers. However, in actual construction, due to the non-smooth concrete, the sealing covers may be punctured when the tube body of the acoustic detection tube is buried, thereby destroying the sealing environment of the entire acoustic detection tube and affecting the detection results of the piles. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a plastic alloy sonic detection tube, strengthen the bottom structure of the sonic detection tube, reduce the phenomenon of internal seal damage of the sonic detection tube, and improve the detection accuracy of piles.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A plastic alloy acoustic detection tube comprises a plurality of groups of first tube bodies and second tube bodies adjacently connected by pipe joints, wherein the end of the first tube body located at the bottom in the burying direction away from the pipe joint is connected to a bottom sealing cover, and the end of the second tube body located at the top in the burying direction away from the pipe joint is connected to a top sealing cover, and a reinforcing cover is provided at the end of the first tube body close to the bottom sealing cover, and the reinforcing cover comprises an extension tube abutting against the inner wall of the first tube body, a flange fixedly connected to the end of the extension tube and abutting against the plane of the tube wall of the first tube body, and a sealing cover fixedly connected to the inner wall of the extension tube.

[0007] Through the above technical scheme, by arranging a reinforcing cover at the end of the first tube body close to the bottom cover when the first tube body is buried, the bottom of the first tube body is sealed by arranging the flange and the sealing cover, so that the reinforcing cover can strengthen the internal seal of the acoustic detection tube. If the bottom cover is broken during the burying process, the sealing protection of the acoustic detection tube can also be completed by the reinforcing cover, the bottom structure of the acoustic detection tube can be strengthened, the phenomenon of the internal seal of the acoustic detection tube being damaged can be reduced, and the detection accuracy of the pile can be improved.

[0008] Furthermore, a buffer cavity recessed toward the pipe joint is formed between the end surface of the flange away from the pipe joint and the end surface of the blocking cover away from the pipe joint.

[0009] Through the above technical solution, when the bottom cover is punctured by concrete or other foreign objects, the damage of the bottom cover is buffered by the buffer cavity, thereby improving the sealing tightness of the reinforced cover and reducing the damage to the reinforced cover after the bottom cover is damaged.

[0010] Furthermore, a plurality of reinforcing ribs connected to the blocking cover and the flange are arranged in the buffer cavity.

[0011] Through the above technical solution, the structural strength of the overall reinforcement cover is increased by the reinforcement ribs, so that the sealing of the first tube body by the reinforcement cover is tighter and more reliable.

[0012] Furthermore, the end surface of the reinforcing rib away from the pipe joint is flush with the end surface of the flange away from the pipe joint.

[0013] Through the above technical solution, the flange is set flush with the flange, so that the entire end face has higher force continuity while having strong structural strength, reducing deformation caused by the force extrusion of the cross-section in the wind direction caused by the stepped surface.

[0014] Furthermore, the end surface of the bottom cover is configured as a curved surface, and transitions in an arc from the direction of the axis of the first tube body to the direction away from the first tube body.

[0015] Through the above technical solution, the bottom cover is set as a curved surface, which is convenient for reducing resistance when the acoustic detection pipe is pre-buried, and is convenient for diverting and stripping concrete or other foreign matter, thereby reducing damage caused by squeezing between concrete or other foreign matter and the bottom cover.

[0016] Furthermore, a plurality of reinforcing ribs are arranged inside the bottom cover.

[0017] Through the above technical solution, the reinforcing ribs are used to improve the structural strength of the bottom cover and reduce the damage of the bottom cover.

[0018] Furthermore, the pipe joint includes a first outer sleeve sleeved on the end of the first tube body away from the bottom sealing cover, an inner sleeve inserted through the first outer sleeve and connected to the second tube body, and a second outer sleeve sleeved on the inner sleeve and threadedly matched with the first outer sleeve, the first outer sleeve having an external threaded section, the second outer sleeve having an internal threaded section matching with the external threaded section; a dust cover covering the tube cavity of the first tube body is connected to the external threaded section.

[0019] Through the above technical solution, the connection between the first tube body and the second tube body is achieved through the connection and cooperation of the first outer tube, the inner tube and the second outer tube, so that the length of the first tube body and the second tube body can be adjusted according to actual construction requirements, or the number of the first tube body and the second tube body can be superimposed.

[0020] The dust cover facilitates temporary sealing of the first tube body during transportation, packaging and construction, thereby reducing the phenomenon of concrete or other impurities falling into the acoustic detection tube.

[0021] Furthermore, a plurality of snap-fitting protrusions corresponding to the external thread segments are arranged inside the dust cover.

[0022] With the above technical solution, a quick connection between the dust cover and the first outer sleeve is achieved through the snap-fitting protrusions in the dust cover.

[0023] Furthermore, the end of the inner sleeve away from the top cover is provided with a limiting sleeve which is threadably matched with the internal thread section.

[0024] Furthermore, the limiting sleeve includes a connecting tube sleeved on the outer wall of the inner sleeve, a limiting ring fixedly connected to the end of the connecting tube away from the second tube body and abutting against the plane of the inner sleeve wall, and a connecting external thread fixedly connected to the outer wall of the connecting tube and cooperating with the internal thread section.

[0025] Through the above technical solution, the limiting sleeve is used to reduce the damage to the inner sleeve during transportation, and the positioning and locking of the second outer sleeve at one end of the second tube body is facilitated, thereby facilitating the quick connection with the first outer sleeve during construction.

[0026] In summary, the present invention has the following beneficial effects: The sealing of the entire acoustic detection tube is further strengthened and protected by reinforcing the cover, thereby enhancing the bottom structure of the acoustic detection tube, reducing the phenomenon of damage to the internal seal of the acoustic detection tube, and improving the accuracy of pile detection.

[0027] The connection between the first pipe body and the second pipe body is achieved through a pipe joint, which makes it easy to adjust the length of the acoustic detection pipe according to construction requirements, meets construction requirements, and through the provision of a dust cover and a limit sleeve, reduces the impact of concrete or foreign objects falling into the acoustic detection pipe on the detection results, and facilitates efficient installation of the acoustic detection pipe.

DETAILED DESCRIPTION

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] A plastic alloy acoustic detection tube, such as Figure 1 As shown, it includes a plurality of first tube bodies 1 and second tube bodies 2 arranged in a hollow cylinder, and a pipe joint 3 is connected between adjacent first tube bodies 1 and second tube bodies 2. By connecting the first tube body 1 and the second tube body 2 through the pipe joint 3, the length of the acoustic detection tube can be spliced ​​according to construction requirements, which is convenient for production, transportation and installation.

[0032] The diameters of the first tube body 1 and the second tube body 2 may be the same. It can be understood that the first tube body 1 and the second tube body 2 refer to two tube bodies connected at both sides of the pipe joint 3, and in this embodiment, the tube body located at the bottom side of the burial direction is the first tube body 1, and the tube body located at the top side of the burial direction is the second tube body 2, so the several tube bodies located at the non-ends of the acoustic detection tube can all be the first tube body 1 or the second tube body 2, and the corresponding pipe joints 3 connected are used to distinguish the two connected tube bodies.

[0033] The end of the first tube body 1 at the bottom of the embedding direction is connected with a bottom cover 4, which is arranged at the end of the first tube body 1 away from the pipe joint 3, and is connected to the outer wall of the first tube body 1 by interference fit.

[0034] like Figure 2 As shown, the end surface of the bottom cover 4 is set as a curved surface, and the end surface transitions in an arc from the axis direction of the first tube body 1 to the direction away from the first tube body 1. A plurality of reinforcing ribs 12 are set in the bottom cover 4.

[0035] The bottom cover 4 is set as a curved surface to reduce resistance when the acoustic detection pipe is pre-buried, and to facilitate the diversion and stripping of concrete or other foreign matter, thereby reducing the damage caused by the squeeze between the concrete or other foreign matter and the bottom cover 4. The reinforcing ribs 12 are used to improve the structural strength of the bottom cover 4 and reduce the damage of the bottom cover 4.

[0036] like Figure 1 As shown, a top sealing cover 5 is connected to the second tube body 2 at the top in the burying direction. The top sealing cover 5 is arranged at the end away from the pipe joint 3. The top sealing cover 5 is detachably connected to the top of the second tube body 2. The connection method can be interference fit, bonding, etc.

[0037] A closed tube body structure can be formed by a bottom cover 4, a plurality of first tube bodies 1 and second tube bodies 2 connected by pipe joints 3, and a top cover 5, which is convenient for evacuating the tube body when the acoustic detection tube is working. At the same time, the top cover 5 detachably connected to the end of the second tube body 2 at the top end in the burial direction can meet the needs of multiple operations in the tube body.

[0038] like Figure 2 and Figure 3 As shown, in order to reduce the phenomenon that the sealing structure in the tube body is damaged due to the bottom end damage of the acoustic detection tube when buried, a reinforcement cover 6 is provided at the end of the first tube body 1 close to the bottom cover 4.

[0039] The reinforcing cover 6 includes an extension tube 7 abutting against the inner wall of the first tube body 1 , a flange 8 fixedly connected to the end of the extension tube 7 and abutting against the tube wall plane of the first tube body 1 , and a blocking cover 9 fixedly connected to the inner wall of the extension tube 7 .

[0040] A reinforcing cover 6 is arranged at the end of the first tube body 1 near the bottom cover 4 when it is buried. The flange 8 and the plugging cover 9 are arranged to seal the bottom of the first tube body 1, so that the reinforcing cover 6 plays a reinforcing role in the internal seal of the acoustic detection tube. If the bottom cover 4 is broken during the burial process, the reinforcing cover 6 can also be used to complete the sealing protection of the acoustic detection tube, strengthen the bottom structure of the acoustic detection tube, reduce the phenomenon of the internal seal of the acoustic detection tube being damaged, and improve the detection accuracy of the pile.

[0041] A buffer cavity 10 is formed between the end surface of the flange 8 away from the pipe joint 3 and the end surface of the blocking cover 9 away from the pipe joint 3. A plurality of reinforcing ribs 11 connected to the blocking cover 9 and the flange 8 are arranged in the buffer cavity 10.

[0042] When the bottom cover 4 is punctured by concrete or other foreign matter, the buffer cavity 10 buffers the damage of the bottom cover 4, thereby improving the sealing tightness of the reinforcement cover 6 and reducing the damage to the reinforcement cover 6 after the bottom cover 4 is broken. The reinforcement ribs 11 increase the structural strength of the overall reinforcement cover 6, so that the reinforcement cover 6 seals the first tube body 1 more tightly and reliably.

[0043] 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. The flange 8 is arranged flush with the flange 8, so that the entire end face has a higher force continuity when having a strong structural strength, and the deformation caused by the force extrusion of the cross section in the wind direction caused by the stepped surface is reduced.

[0044] like Figure 4 As shown, the pipe joint 3 includes a first outer sleeve 13 sleeved on the end of the first tube body 1 away from the bottom cover 4, an inner sleeve 14 passed through the first outer sleeve 13 and connected to the second tube body 2, and a second outer sleeve 15 sleeved on the inner sleeve 14 and threadedly matched 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 matched with the external thread section 16.

[0045] The first outer sleeve 13 is fixedly connected to the end of the first tube body 1, which may be fixed by bonding, and the second outer sleeve 15 can slide along the axial direction of the second tube body 2, and the second outer sleeve 15 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 may be fixed by bonding, and the inner sleeve 14 has a stepped surface, which acts as a limit on the second outer sleeve 15 sleeved outside the second tube body 2, thereby preventing the second outer sleeve 15 from being separated from the second tube body 2.

[0046] 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 is used to seal the connection between the first tube body 1 and the second tube body 2 .

[0047] The acoustic detection tube is located in a tube body at positions other than the two ends. The second outer sleeve 15 is provided at the bottom end of the same tube body in the burying direction, and the first outer sleeve 13 is provided at the top end.

[0048] like Figure 5 and Figure 6As shown, when the external thread segment 16 is not threadedly matched with the internal thread segment 17 , a dust cover 18 covering the tube cavity of the first tube body 1 is connected to the external thread segment 16 , and a plurality of snap-fit ​​protrusions 19 corresponding to the external thread segment 16 are arranged inside the dust cover 18 .

[0049] The snap-fit ​​protrusion 19 can be a threaded section or protrusion 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 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.

[0050] The dust cover 18 and the first outer sleeve 13 are quickly connected by the snap-fitting protrusions 19 in the dust cover 18. The dust cover 18 is arranged on the opening of the first tube body 1 to facilitate temporary sealing of the first tube body 1 during transportation, packaging, and construction, and to reduce the phenomenon of concrete or other impurities falling into the acoustic detection tube.

[0051] like Figure 7 and Figure 8 As shown, the end of the inner sleeve 14 away from the top cover 5 is sleeved with a limiting sleeve 20 threadably matched with the internal thread section 17.

[0052] The limiting sleeve 20 includes a connecting tube 21 sleeved on the outer wall of the inner sleeve 14, a limiting ring 22 fixedly connected to the end of the connecting tube 21 away from the second tube body 2 and abutting against the tube wall plane of the inner sleeve 14, and a connecting external thread 23 fixedly connected to the outer wall of the connecting tube 21 and matched with the internal thread section 17. The connecting external thread 23 can be a continuous thread end or an intermittent thread section.

[0053] The limiting sleeve 20 can reduce the damage to the inner sleeve 14 during transportation and facilitate the positioning and locking of the second outer sleeve 15 at one end of the second tube body 2, thereby facilitating the quick connection with the first outer sleeve 13 during construction.

[0054] The dust cover 18 and the limiting sleeve 20 can be used temporarily during transportation and installation, and need to be removed when the installation of the acoustic detection tube is completed.

[0055] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
