Description

Technical Field

[0001] The utility model belongs to the field of building inspection, and particularly relates to a crack repair quality inspection device and an inspection system. Background Art

[0002] Cracks in concrete structures are one of the most common concrete diseases. During the use of various wharf projects, cracks will occur under the influence of temperature or load. Although the occurrence of a small number of cracks has little impact on the structure's load-bearing capacity, the occurrence and development of cracks are likely to cause water to penetrate into the interior of the concrete. For the steel bars inside the concrete, an environment prone to corrosion is formed. After the steel bars are corroded, the reduction of the steel bar diameter will pose a great hidden danger to the structural safety. Therefore, after the wharf maintenance unit discovers cracks in the concrete structure, it usually adopts a repair method to seal the cracks, and the most common one is grouting repair.

[0003] However, at present, there is no special equipment and method for detecting the quality of concrete grouting repair, and it is impossible to judge whether the cracks are completely sealed to prevent water intrusion, thereby reducing the probability of steel bar corrosion. Therefore, it is necessary to detect the quality of crack repair. The existing technology generally detects the quality of grouting repair by opening a pre-drilled hole at the crack and injecting water with a certain pressure into the pre-drilled hole. However, after drilling a pre-drilled hole at the crack, an additional device is needed to remove the dust in the hole before inserting the liquid injection device for detection. Therefore, more devices are required and the operation is not simple. Summary of the Utility Model

[0004] In view of the above problems, the embodiments of the present application provide a crack repair quality inspection device and an inspection system that can complete the dust removal and liquid injection detection of the pre-drilled hole, and the operation is simple.

[0005] In a first aspect, the embodiments of the present application provide a crack repair quality inspection device for being inserted into a pre-drilled hole for testing the crack repair quality. The crack repair quality inspection device includes a first pipe body and a second pipe body. The first pipe body has a first end for air or water to enter its interior and a second end located in the pre-drilled hole for air or water to leave its interior. The circumferential side of the first pipe body has a first through hole. The second pipe body is rotatably sleeved outside the first pipe body. The circumferential side of the second pipe body has a second through hole corresponding to the first through hole. The first pipe body has a first position and a second position, and the first pipe body is configured to: when in the first position, the first through hole and the second through hole are communicated; when in the second position, the pipe wall of the second pipe body blocks the first through hole.

[0006] Specifically, after the pre-drilling hole is drilled, insert the crack repair quality detection device into the pre-drilling hole, and make the second end located in the pre-drilling hole. Then rotate the first pipe body so that the first pipe body is in the second position. Then inject air into the first pipe body through the first end, so that the air only leaves the interior of the first pipe body from the second end, and drives the dust in the pre-drilling hole to leave the pre-drilling hole through the gap between the outer peripheral side of the second pipe body and the hole wall of the pre-drilling hole. Then rotate the first pipe body so that the first pipe body is in the first position. After completing the sealing of the gap between the outer peripheral side of the second pipe body and the hole wall of the pre-drilling hole, inject water into the first pipe body through the first end, so that the water enters the pre-drilling hole from the peripheral side and the second end of the second pipe body, to uniformly increase the pressure in the pre-drilling hole, and complete the quality detection of the repair condition of the crack.

[0007] In the above technical solution, it is possible to complete the dust cleaning and injection pressure of the pre-drilling hole without unplugging and replacing different devices, reducing the number of devices required for crack repair quality detection and simplifying the operation process during crack repair quality detection.

[0008] In some embodiments, the crack repair quality detection device further includes a spring ball pin. The spring ball pin has a fixed end and a ball end. The outer peripheral side of the first pipe body has a blind hole, and the peripheral side of the second pipe body has a third through hole corresponding to the blind hole. The fixed end is arranged in the blind hole. In the first position, the ball end is inserted into the third through hole.

[0009] In some embodiments, the first through holes are multiple and are arranged at intervals along the axial direction of the first pipe body.

[0010] In some embodiments, the crack repair quality detection device further includes an expansion assembly. The expansion assembly is sleeved outside the second pipe body. Along the axial direction of the first pipe body, the first through hole is located between the expansion assembly and the second end. The expansion assembly is used to expand when the first through hole and the second through hole are communicated, so as to block the gap between the second pipe body and the hole wall of the pre-drilling hole.

[0011] In some embodiments, the expansion assembly further includes a rubber gasket and a pressing member. The second pipe body includes a first section and a second section connected to each other. The first section is located on the side of the second section away from the second end. The radial dimension of the second section is larger than that of the first section, so as to form a first stepped surface on the peripheral side of the second pipe body. The rubber gasket is sleeved outside the first section. The pressing member is sleeved outside the first section in an axially adjustable manner. The pressing member moves in the direction close to the second end to press the rubber gasket against the first stepped surface and make the rubber gasket expand, so as to block the gap between the second pipe body and the hole wall of the pre-drilling hole.

[0012] In some embodiments, the pressing member is threadedly connected to the second pipe body.

[0013] In some embodiments, the crack repair quality detection device further includes a pressure detection mechanism for detecting the pressure inside the first pipe body.

[0014] In some embodiments, the crack repair quality detection device further includes a first water stop valve disposed at the first end and configured to open or close the first end.

[0015] In a second aspect, an embodiment of the present application provides a detection system, including the above-mentioned crack repair quality detection device, a pressure pump, a first connection pipe, and a second connection pipe. The pressure pump has an input end and an output end. Two ends of the first connection pipe are respectively communicated with the first end and the output end. One end of the second connection pipe is communicated with a water source, and the other end of the second connection pipe is detachably connected to the input end. When the other end of the second connection pipe is communicated with the input end, the pressure pump is configured to drive water to move through the first connection pipe towards the first end; when the other end of the second connection pipe is not communicated with the input end, the pressure pump is configured to drive air to move through the first connection pipe towards the first end.

[0016] In some embodiments, multiple crack repair quality detection devices are arranged at intervals along the extension direction of the crack. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] Concrete structure cracks are one of the most common concrete diseases. During the use of various wharf 200 projects, cracks will occur under the influence of temperature or load effects. Although the occurrence of a small number of cracks has little impact on the structure's load-bearing capacity, the occurrence and development of cracks are likely to cause water to penetrate into the concrete interior. For the steel bars inside the concrete, an environment prone to corrosion is formed. After the steel bars are corroded, the reduction of the steel bar diameter will pose a great hidden danger to the structural safety. Therefore, after the wharf 200 maintenance unit discovers cracks in the concrete structure, it usually adopts a repair method to seal the cracks, and the most common one among them is grouting repair.

[0025] However, currently, there is no special equipment or method for detecting the quality of concrete grouting repair. It is impossible to determine whether the cracks have been completely sealed to prevent water intrusion, thereby reducing the probability of steel bar corrosion. Therefore, it is necessary to detect the quality of crack repair. The prior art generally detects the quality of grouting repair by drilling pre-holes 210 at the cracks and injecting water with a certain pressure into the pre-holes 210. However, after drilling the pre-holes 210 at the cracks, it is necessary to use additional devices to remove the dust in the holes and then insert the liquid injection device for detection. Therefore, more devices are required and the operation is not convenient.

[0026] To solve the above technical problems, with reference to Figure 1, an embodiment of the present application provides a crack repair quality detection device 10, which is used to be inserted into a pre-drilled hole 210 for testing the crack repair quality. The crack repair quality detection device 10 includes a first pipe body 1 and a second pipe body 2. The first pipe body 1 has a first end 11 for air or water to enter its interior and a second end 12 located in the pre-drilled hole 210 for air or water to leave its interior. A first through hole 13 is provided on the circumferential side of the first pipe body 1. The second pipe body 2 is rotatably sleeved outside the first pipe body 1. A second through hole 21 corresponding to the first through hole 13 is provided on the circumferential side of the second pipe body 2. The first pipe body 1 has a first position and a second position. The first pipe body 1 is configured such that: when in the first position, the first through hole 13 and the second through hole 21 are communicated; when in the second position, the pipe wall of the second pipe body 2 blocks the first through hole 13.

[0027] The first pipe body 1 and the second pipe body 2 are tubular hollow parts.

[0028] The first end 11 and the second end 12 are two open ends of the first pipe body 1 in its axial direction. The first through hole 13 is a through hole provided on the circumferential wall of the first pipe body 1 to communicate the outside with the interior of the first pipe body 1. The second through hole 21 is a through hole provided on the circumferential wall of the second pipe body 2 to communicate the outside with the interior of the second pipe body 2.

[0029] It can be understood that when the first through hole 13 is aligned with the second through hole 21 (i.e., when the first pipe body 1 is in the first position), the water in the second pipe body 2 can enter the pre-drilled hole 210 successively through the first through hole 13 and the second through hole 21.

[0030] In some embodiments, one end of the second pipe body 2 near the second end 12 has a guiding surface, and the guiding surface is used to guide the crack repair quality detection device 10 to be inserted into the pre-drilled hole 210.

[0031] Specifically, after the pre-drilled hole 210 is drilled, the crack repair quality detection device 10 is inserted into the pre-drilled hole 210, and the second end 12 is located in the pre-drilled hole 210. Subsequently, the first pipe body 1 is rotated so that the first pipe body 1 is in the second position. Then, air is injected into the first pipe body 1 through the first end 11, so that the air only leaves the interior of the first pipe body 1 from the second end 12, and drives the dust in the pre-drilled hole 210 to leave the pre-drilled hole 210 through the gap between the outer peripheral side of the second pipe body 2 and the hole wall of the pre-drilled hole 210. Subsequently, the first pipe body 1 is rotated so that the first pipe body 1 is in the first position. After the gap between the outer peripheral side of the second pipe body 2 and the hole wall of the pre-drilled hole 210 is sealed, water is injected into the first pipe body 1 through the first end 11, so that the water enters the pre-drilled hole 210 from the circumferential side and the second end 12 of the second pipe body 2, so as to uniformly increase the pressure in the pre-drilled hole 210 and complete the quality detection of the repair condition of the gap.

[0032] In this technical solution, it is possible to complete the dust cleaning and injection pressure of the pre-drilled hole 210 without unplugging and replacing different devices, reducing the number of devices required for crack repair quality inspection and simplifying the operation process during crack repair quality inspection.

[0033] According to some embodiments of the present application, referring to Figure 1 , the crack repair quality inspection device 10 further includes a spring ball pin 3. The spring ball pin 3 has a fixed end and a ball end. The outer peripheral side of the first tube body 1 has a blind hole, and the circumferential side of the second tube body 2 has a third through hole 22 corresponding to the blind hole. The fixed end is arranged in the blind hole. In the first position, the ball end is inserted into the third through hole 22.

[0034] The spring ball pin 3 is a common positioning pin and may include a pin, a spring, and a ball. One end of the pin is provided with a blind hole. The ball is arranged in the blind hole so as to move axially along the pin, and the radial dimension at the opening of the blind hole is smaller than the radial dimension of the ball, so that the ball cannot leave the blind hole through the opening of the blind hole. The spring is arranged between the bottom of the blind hole and the ball and is used to provide an elastic force to the ball to press the ball against the opening of the blind hole and make a part of the ball located outside the blind hole. In some embodiments, the spring ball pin 3 may also only include a spring and a ball.

[0035] Specifically, when the first tube body 1 is in the second position, the ball is pressed into the blind hole by the inner wall of the second tube body 2, so that the spring is compressed. When the first tube body 1 is in the second position, the blind hole is aligned with the third through hole 22, so that the spring is restored, and a part of the ball is located outside the blind hole and in the third through hole 22 to limit the rotation of the first tube body 1 relative to the second tube body 2.

[0036] In this technical solution, when the second tube body 2 is in the first position, the rotation of the first tube body 1 is restricted to a certain extent by the spring tube cancellation, thereby reducing the risk of the first tube body 1 rotating during the detection process.

[0037] According to some embodiments of the present application, referring to Figure 1 , the first through holes 13 are multiple and are arranged at intervals along the axial direction of the first tube body 1.

[0038] In this technical solution, the first through holes 13 are multiple and are arranged at intervals along the axial direction of the first tube body 1, so that water can enter the pre-drilled hole 210 more evenly, and the pressure in the pre-drilled hole 210 rises evenly, thereby improving the accuracy of the detection.

[0039] According to some embodiments of the present application, referring to Figure 1, the crack repair quality detection device 10 further includes an expansion assembly 4. The expansion assembly 4 is sleeved outside the second tube body 2. Along the axial direction of the first tube body 1, the first through hole 13 is located between the expansion assembly 4 and the second end 12. The expansion assembly 4 is used to expand when the first through hole 13 and the second through hole 21 are communicated, so as to block the gap between the second tube body 2 and the hole wall of the pre-drilled hole 210.

[0040] The expansion assembly 4 is a mechanical structure that expands when the first through hole 13 and the second through hole 21 are communicated, so as to block the gap between the second tube body 2 and the hole wall of the pre-drilled hole 210.

[0041] Exemplarily, the expansion assembly 4 can be an inflatable airbag. When the outside inflates the expansion assembly 4, the expansion assembly 4 expands to block the gap between the second tube body 2 and the hole wall of the pre-drilled hole 210.

[0042] In this technical solution, the gap between the second tube body 2 and the hole wall of the pre-drilled hole 210 is blocked by the expansion assembly 4, so that no other device needs to be installed, simplifying the detection process.

[0043] According to some embodiments of the present application, the expansion assembly 4 further includes a rubber gasket 41 and a pressing member 42. The second tube body 2 includes a first section and a second section connected to each other. The first section is located on the side of the second section away from the second end 12. The radial dimension of the second section is greater than that of the first section to form a first step surface on the circumferential side of the second tube body 2. The rubber gasket 41 is sleeved outside the first section. The pressing member 42 is sleeved outside the first section in an axially adjustable manner along the first tube body 1. The pressing member 42 moves in the direction close to the second end 12 to press the rubber gasket 41 against the first step surface and expand the rubber gasket 41 to block the gap between the second tube body 2 and the hole wall of the pre-drilled hole 210.

[0044] The rubber gasket 41 is a common flexible gasket. The pressing member 42 can be a pressing gasket or other parts.

[0045] In some embodiments, the pressing member 42 can be in interference fit with the first section so that the pressing member 42 can move axially adjustably along the first section.

[0046] It can be understood that when the rubber gasket 41 abuts against the hole wall of the pre-drilled hole 210, the rubber gasket 41 can limit the rotation of the second tube body 2 relative to the pre-drilled hole 210 to a certain extent, thereby facilitating the operator to rotate the first tube body 1 so that the first tube body 1 switches from the second position to the first position to prepare for liquid injection detection.

[0047] In this technical solution, the rubber gasket 41 is pressed against the first step surface by the pressing member 42 and the rubber gasket 41 is expanded to block the gap between the second tube body 2 and the hole wall of the pre-drilled hole 210, and the structure is simple and easy to implement.

[0048] According to some embodiments of the present application, with reference to Figure 1 , the pressing member 42 is threadedly connected to the second pipe body 2.

[0049] In this technical solution, the pressing member 42 is threadedly connected to the second pipe body 2. On the one hand, by rotating the pressing member 42, the rubber gasket 41 can be pressed, and the structure is simple and easy to implement. On the other hand, the threaded connection has a certain self-locking ability, which can reduce the risk of the pressing member 42 not being pressed tightly against the rubber gasket during liquid injection detection, resulting in sealing failure.

[0050] According to some embodiments of the present application, with reference to Figure 1 , the crack repair quality detection device 10 further includes a pressure detection mechanism 6 for detecting the pressure inside the first pipe body 1.

[0051] The pressure detection mechanism 6 can be a pressure gauge, and the test end of the pressure gauge is arranged inside the first pipe body 1 to measure the pressure inside the first pipe body 1 and the pre-drilled hole 210.

[0052] According to some embodiments of the present application, with reference to Figure 1 , the crack repair quality detection device 10 further includes a first water stop valve 5 arranged at the first end 11 and used to open or close the first end 11.

[0053] In this technical solution, by closing the first water stop valve 5, the pressure inside the first pipe body 1 and the pre-drilled hole 210 can be maintained during detection, and the structure is simple and easy to implement.

[0054] According to some embodiments of the present application, with reference to Figure 1 and Figure 2 , an embodiment of the present application provides a detection system 100, including the above-mentioned crack repair quality detection device 10, a pressure pump 20, a first connecting pipe 30, and a second connecting pipe 40. The pressure pump 20 has an input end and an output end. Two ends of the first connecting pipe 30 are respectively communicated with the first end 11 and the output end. One end of the second connecting pipe 40 is communicated with a water source, and the other end of the second connecting pipe 40 is detachably connected to the input end. When the other end of the second connecting pipe 40 is communicated with the input end, the pressure pump 20 is used to drive water to move towards the first end 11 through the first connecting pipe 30; when the other end of the second connecting pipe 40 is not communicated with the input end, the pressure pump 20 is used to drive air to move towards the first end 11 through the first connecting pipe 30.

[0055] The pressure pump 20 can be a manual pump, an electric pump, or an oil pump. With reference to Figure 2 , a manual pump is adopted in this embodiment for easy carrying, and it has a pressing end 21 for driving the pump body.

[0056] The water source includes a water bucket 50 for containing water. Further, a second water stop valve 51 is provided on the water bucket 50. One end of the second connecting pipe 40 communicates with the inside of the water bucket 50 through the second water stop valve 51, and the second water stop valve 51 is used to cut off and connect the second connecting pipe 40 and the water bucket 50.

[0057] Still further, the water source further includes an electronic scale 60 for weighing the mass of the water in the water bucket 50.

[0058] Specifically, after the pre-drilled hole 210 is drilled, the crack repair quality detection device 10 is inserted into the pre-drilled hole 210. At this time, the expansion assembly 4 is not expanded, and the first pipe body 1 is in the second position, and the other end of the second connecting pipe 40 is not connected to the input end. At this time, the pressing end 21 of the pressure pump 20 is pressed to supply gas to the first pipe body 1, so that air enters the pre-drilled hole 210 from the second end 12 and drives the dust out of the pre-drilled hole 210.

[0059] Subsequently, the expansion assembly 4 expands to block the gap between the pre-drilled hole 210 and the second pipe body 2, and the first pipe body 1 is in the first position. At the same time, the other end of the second connecting pipe 40 is connected to the input end. At this time, the pressing end 21 of the pressure pump 20 is pressed to supply water to the first pipe body 1, so that air enters the pre-drilled hole 210 from the second end 12 and the first through hole 13. The pressure pump 20 is slightly applied to a water pressure of about 0.05 MPa and left standing for 2 minutes, so that the water can fill the entire pre-drilled hole 210. Then, the pressure is increased in stages at 0.1 MPa. When the pressure reaches 70% of the grouting pressure, the pressure increase can be stopped. The crack grouting repair quality is judged by whether there is water leakage on the crack surface and the stability of the pressure gauge reading.

[0060] According to some embodiments of the present application, a plurality of crack repair quality detection devices 10 are arranged at intervals along the crack extension direction.

[0061] In some embodiments, the first connecting pipe 30 is connected to a plurality of crack repair quality detection devices 10 respectively through a multi-way joint 31.

[0062] In this technical solution, a plurality of crack repair quality detection devices 10 are arranged at intervals along the crack extension direction, so as to facilitate the detection of the repair quality of each part of the crack at one time.

[0063] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0064] The above embodiments are only used to illustrate the technical solutions of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
