Description

Technical Field

[0001] The utility model relates to the technical field of deep-buried structure construction, in particular to an anti-blocking pipe device for an acoustic detection pipe. Background Art

[0002] In the construction of deep buried structures, in order to detect the construction quality of the structure, it is necessary to install an acoustic detection tube in the structural steel grid before pouring the structure, and then pour cement. For example, acoustic detection tubes are often used in the construction of underground continuous walls, and the acoustic detection tubes will be buried as a whole in the structure casting. After the coagulation strength of the poured concrete reaches the standard, the over-poured concrete on the top of the structure is usually broken mechanically to expose the top of the acoustic detection tube, and then a detection instrument is placed in the acoustic detection tube to detect the construction quality of the structure. However, during the construction process, the acoustic detection tube is easily damaged and broken in the process of mechanically breaking the concrete on the top of the structure. The concrete debris generated during the breaking will fall into the acoustic detection tube through the damaged part, seriously blocking the inner cavity of the acoustic detection tube, making it difficult to lower the detection instrument to the bottom of the acoustic detection tube. Therefore, there is an urgent need for an anti-blocking pipe device for the acoustic detection tube. Utility Model Content

[0023] Example: See Figure 1 and Figure 2 As shown, an anti-blocking pipe device for an acoustic detection tube of an embodiment is shown, which includes a capsule air bag 1 that can be loaded into the acoustic detection tube and can be expanded along the radial direction of the acoustic detection tube; an inflation core tube 5 that is detachably installed in the capsule air bag 1; and an inflation hose 9 that is detachably installed with the inflation core tube 5 that is exposed from the capsule air bag 1.

[0024] In this embodiment, the capsule air bag 1 includes an air inlet pipe 2 , in which a first internal thread 4 communicating with the interior of the capsule air bag 1 is provided, and a wristband 3 is installed on the air inlet pipe 2 .

[0025] In this embodiment, Figure 2 As shown, the inflatable core tube 5 is hollow and has a first external thread 6 and an outwardly protruding closed structure at both ends. The side wall of the inflatable core tube 5 has an air outlet 8, and a belt ring 7 is protruding outward in the middle peripheral direction of the inflatable core tube 5.

[0026] In this embodiment, Figure 3 As shown, the inflatable hose 9 is hollow and has a second internal thread 12 and a second external thread 11 at both ends. The inflatable core tube 9 is connected to the air inlet pipe 2 through the first external thread 6 and the first internal thread 4. The inflatable core tube 5 is also covered with a rubber cover (not shown) for sealing, and the rubber cover at least covers the outer convex closed opening, the air outlet 5 and the belt loop 7. The air outlet holes 8 are arranged in pairs at opposite positions on the side wall of the inflatable core tube 5, and the inflatable hose 6 is connected to the inflatable core tube 5 through the second internal thread 12 and the first external thread 6.

[0027] In this embodiment, the maximum outer diameter of the belt ring 7 is greater than the outer diameter of the inflation core tube 5 .

[0028] The characteristics and functions of the present invention can be further understood through the following description.

[0029] The main body of the anti-blocking pipe device of this embodiment is a capsule air bag 1 with a capsule shape, which can be inflated inside and expand evenly along the four sides, and the material has a certain strength. An air inlet pipe 2 is provided at one end of the capsule air bag 1; a wristband 3 is provided on the top of the air inlet pipe 2, and the wristband 3 is a soft belt for conveniently pulling the capsule air bag 1; a first internal thread 4 is provided inside the air inlet pipe 2, and after the external inflation core tube 5 is inserted into the air inlet pipe 2, the first external thread 6 at the end of the inflation core tube 5 is screwed and connected with the first internal thread 4 of the air inlet pipe 2.

[0030] The inflatable core tube 5 is hollow inside, one end is open and provided with a first external thread 6 on the outside, and the other end is convex and closed. When inflating, the gas enters the capsule air bag 1 through the air outlet 8 provided in the middle of the inflatable core tube 5. In order to ensure that the gas in the capsule air bag 1 will not overflow through the inflatable core tube 5 after the inflation is completed, a rubber sleeve (not shown) is covered on a section of the closed end of the inflatable core tube 5 during use. The length of the rubber sleeve covers the air outlet 8 and at least covers the belt loop 7 provided in the middle of the inflatable core tube 5. The cross-sectional size of the belt loop 7 is larger than the inflatable core tube 5, and partially protrudes from the outer surface of the inflatable core tube 5, so as to restrain the rubber sleeve and prevent it from falling off easily.

[0031] The length of the first external thread 6 at the end of the inflation core tube 5 exceeds the length of the first internal thread 4 of the air inlet pipe 2. After the first external thread 6 is tightened with the first internal thread 4, the exposed section of the first external thread 6 can be screwed and connected with the second internal thread 12 at the end of the inflation hose 9; the inflation hose 9 has a certain length, the end 10 is provided with a second internal thread 12, and the other end is provided with a second external thread 11. The end 10 can be connected to the inflation core tube 5 of the capsule air bag 1 to pressurize and inflate the capsule air bag 5; when the length of the inflation hose 9 is insufficient, the other end of the inflation hose 9 is connected to the end 10 of another inflation hose 9 to extend the inflation hose.

[0032] In actual use, the capsule air bag 1, the inflation core tube 5 (covered with a rubber sleeve), and the inflation hose 9 are first connected and assembled, and the assembled, uninflated capsule air bag 1 is inserted into the acoustic detection tube to a certain depth, so that its position elevation is lower than the design elevation of the structure to be broken. Before pouring concrete and before temporarily blocking the end of the acoustic detection tube, the exposed inflation hose 9 is used to pressurize and inflate the capsule air bag 1 to expand it. The inflated capsule air bag 1 completely blocks the acoustic detection tube below its elevation, and then the exposed inflation hose 9 is bent back and inserted into a section of the acoustic detection tube that is about to be temporarily blocked. Finally, after the end of the acoustic detection tube is sealed, the structural concrete is poured.

[0033] After the structural end is broken, for the damaged acoustic detection tube, it is only necessary to clean the concrete rubble above the elevation of the capsule air bag 1. The concrete rubble cannot pass through the capsule air bag 1 and fall into the bottom acoustic detection tube; after the cleaning is completed, remove the inflation core tube 5, release the gas in the capsule air bag 1, and then the capsule air bag 1 can be easily taken out.

[0034] Another usage scenario: When the end of the structure is broken, to ensure that the acoustic detection tube is not damaged, or is rarely damaged, the inflatable core tube 5 of the capsule air bag 1 can be connected to the external thread of the inflatable hose 9, and the inflatable core tube 5 (covered with a rubber sleeve) is connected to the internal thread of the inflatable hose 9, and the inflating device sequentially passes the pressurized gas through the inflatable core tube 5 and the inflatable hose 9 into the capsule air bag 1. When the acoustic detection tube is not damaged, the capsule air bag 1 can be deflated at the exposed end of the inflatable hose 9 to facilitate the removal of the capsule air bag 1 from the undamaged acoustic detection tube.

[0035] To sum up, the utility model achieves the sealing of the part below the breaking structure of the acoustic detection tube before the acoustic detection tube is sealed through the mutually detachable capsule air bag, inflation core tube and inflation hose, so as to prevent the broken stones from falling into the acoustic detection tube and clogging the inner cavity when the acoustic detection tube is broken, making it difficult to lower the detector to the bottom of the acoustic detection tube, thus affecting the detection.
