Description

Technical Field

[0001] The present invention relates to the technical field of building structure detection, and specifically to a water seepage detection device for building construction. Background Art

[0002] In building engineering, concrete is usually used as the base layer, and asphalt is laid on the base layer for vehicles to drive on. During the construction process, prefabricated structural components are transported to the site for installation. In this way, the construction speed is faster and the construction efficiency is higher. Therefore, the water seepage detection of the prefabricated structural components is particularly important. By sampling and detecting the prefabricated structural components, compared with sampling by damaging the construction surface on site, it is more convenient and simpler. Therefore, when the structural components enter the construction site, the water seepage detection of the structural components is carried out in advance.

[0003] The Chinese patent discloses a water seepage detection device for bridge construction (publication number CN117825234A). The detection device includes a protective shell. At the top end inside the protective shell, there is a servo motor, and the output end of the servo motor is fixed with a lead screw. The lead screw is rotationally connected to the upper partition plate of the protective shell through a bearing. One end of the lead screw extending below the partition plate is threadedly sleeved with an adjustment sleeve. In the present invention, through the lead screw and the sleeve, the drill cylinder can be made to not require manual control of the process during use, ensuring the core sampling accuracy. At the same time, by the method of first drilling to take a core and then storing water for detection, it solves the problem that the existing water seepage detection device for bridge construction will cause partial evaporation of the water seepage layer due to the heat during the core sampling process, resulting in unclear imaging and thus low detection accuracy. It improves the accuracy of the detection device and avoids the influence of temperature on the detection accuracy during core sampling.

[0004] In the above technical solution, the materials at the construction site are sampled by on-site drilling for testing. However, during the testing process, the building materials that are already under construction will be damaged, and the damage is relatively large. Moreover, once problems are detected, on-site demolition is required, and the subsequent treatment procedures are relatively complex. In addition, the single-sided and one-way water seepage detection method is still used during the testing, which is not conducive to realizing the two-way water seepage detection inside and outside, and it is easy to have the situation of quality stratification on the same structural member. For example, the external water seepage is qualified, but there are quality problems inside. In the prior art, the structural member is pre-cast and formed into an assembled structural member, and after being transported to the construction site, the structural member is assembled. In this way, the construction efficiency is higher. Before the structural member reaches the construction site, sampling of the structural member is mainly to complete various tests on the structural member, and the water seepage test is very important among them. Through the water seepage test, it is detected whether the structural member will leak water, so as to control the construction quality. At present, when detecting the water seepage of the structural member, the water seepage situation inside the structural member is detected by soaking and watering to penetrate the structural member. However, during the detection process, the water penetration path is all from the external path to penetrate, so as to detect the water seepage situation inside the structural member. During the construction process of the structural member, holes will be drilled and fasteners and other equipment will be driven in. In this way, by sampling the structural member for water seepage detection, only the water seepage situation from the outside to the inside of the structural member can be detected, and the water seepage situation from the inside to the outside is not detected. When water enters the inside of the structural member through cracks and other gaps, the water seepage situation from the inside to the outside of the structural member will also corrode the inside of the structural member, causing damage to the inside of the structural member, resulting in the situation of water seepage stratification between the inside and the outside of the structural member. The water seepage situation from the inside to the outside is relatively serious, while the water seepage from the outside to the inside can be isolated. In this way, the quality of the structural member will still have problems, resulting in an incomplete detection direction during the detection and not considering the water seepage test of the structural member under different conditions.

[0005] Therefore, those skilled in the art have provided a water seepage detection device for building construction to solve the problems raised in the above background technology. Summary of the Invention

On the surface of the node gear, a slave gear is integrally connected, and on the outer side of the slave gear, a driving gear is meshingly installed. On the surface of the driving gear, a toothed belt is provided, and below the inside of the toothed belt, a driving gear is installed. At the front end of the mounting rod, a drill bit is installed, and on the front surface of the mounting rod, a water seepage hole is provided. Inside the water seepage hole, a connecting pipe is connected, and the upper end of the connecting pipe is connected to an injection cylinder.

[0008] As an implementation manner of the present invention, the suction cup cover and the silica gel adsorption disc are fixedly connected, and the silica gel adsorption disc is closely attached to the surface of the structural member sample.

[0009] As an implementation manner of the present invention, the suction cup cover is symmetrically arranged up and down with respect to the symmetry center line of the structural member sample, and the suction cup cover is connected to the support platform through the support hollow column.

[0010] As an implementation manner of the present invention, the adjusting arm and the support table are of a rotating structure, and the operation box and the sliding rod form a sliding structure.

[0011] As an embodiment of the present invention, the mounting rod is meshed with the rotating gear through the tooth grooves on the surface, and the mounting rod and the node gear form a meshing connection structure, and the node gears are equidistantly distributed and mounted along the rotating shaft.

[0012] As an embodiment of the present invention, the node gear forms a meshing connection structure with the driven gear through the driven gear, and the driven gear is connected to the driving gear through a toothed belt.

[0013] As an embodiment of the present invention, the lower end of the arm rod is rotatably connected to the mounting base, and the arm rod and the rotating shaft form a rotating structure.

[0014] As an embodiment of the present invention, a reinforcing base is installed at the bottom of the support platform, and a bottom platform is installed below the reinforcing base. A lead screw passes through the interiors of the bottom platform, the reinforcing base, and the support platform.

[0015] As an embodiment of the present invention, the outer edge of the bottom platform is rotatably connected to a carbon steel support frame, and the inner wall of the carbon steel support frame is rotatably connected to an adjusting rod. A nut moving platform is slidably installed on the surface of the lead screw.

[0016] As an embodiment of the present invention, the nut moving platform is rotatably connected to one end of the adjusting rod, and the end of the adjusting rod away from the nut moving platform is rotatably connected to the carbon steel support frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. Suction cup covers are provided at both the upper and lower ends of the structural member sample. The bottom of the suction cup cover is connected to a support hollow column, and the support hollow column is interconnected with the support platform. The support platform supports the suction cup cover. An air intake port is provided inside the suction cup cover, and the air intake port is interconnected with a vacuum suction machine through a pipeline. The vacuum suction machine is used to evacuate the inside of the suction cup cover to a vacuum environment. A silicone adsorption disc is integrally provided at the upper edge of the suction cup cover, and the silicone adsorption disc fits the upper and lower ends of the structural member sample. After being evacuated to a vacuum, the silicone adsorption disc will tightly adhere to the surface of the structural member sample. In this way, the sealing performance inside the adsorption cover is improved. A water pipe is connected to the adsorption cover, and the water pipe is interconnected with the injection port inside the adsorption cover. Water is injected into the suction cup cover through the water pipe. After water is injected into the suction cup cover, the water will fit the structural member, making the surface of the structural member always in contact with water, and thus soaking the surface of the structural member sample. The suction cup covers are provided on the upper and lower sides, and the upper and lower sides simultaneously conduct a water seepage test on the structural member sample. In this way, the water seepage conditions of the upper and lower parts of the structural member can be detected, rather than simply detecting the water seepage of the upper part of the structural member. Because in actual use, water not only seeps downward from the upper surface, but also flows along the outer wall of the building structure to the back of the structural member and seeps from the bottom up. Therefore, single-sided detection is not comprehensive enough. By simultaneously conducting a water seepage test using the upper and lower adsorption covers, the water seepage conditions of the front and back surfaces of the structural member can be detected simultaneously, improving the comprehensiveness of detection; 2. Inclined holes are drilled on the surface of the structural member sample, so that inclined holes are provided on the surface of the structural member sample. Through the inclined holes, it is convenient to inject water into the inside of the structural member, thereby detecting the structural member from the inside out. A sliding rod is installed at the upper end of the adjusting arm, and the operating box slides along the sliding rod. An installation rod is installed inside the operating box, and a drill bit is connected to the front end of the installation rod. By adjusting the angle of the adjusting arm, holes are drilled on the surface of the structural member sample. The injection cylinder is interconnected with the water seepage hole through a connecting pipe. Water is injected into the water seepage hole through the connecting pipe using the injection cylinder, and the water is poured into the inclined hole through the water seepage hole to soak the inside of the structural member. The water will conduct a water seepage test from the inside out of the structural member, thereby avoiding the situation of water seepage stratification between the inside and outside of the structural member, resulting in a qualified water seepage test on the surface of the structural member, but a serious water seepage situation from the inside out inside. In this way, the quality of the structural member will still have problems. When conducting a water seepage test on the inside of the structural member from the inside out, it is beneficial to improve the comprehensiveness of the detection direction during detection, considering the water seepage test of the structural member under different conditions and improving the detection effectiveness; 3. On the outside of the mounting base, there is an arm rod rotatably connected. An ultrasonic detector is installed at the upper end of the arm rod. A sticker cylinder is connected to the ultrasonic detector and closely adheres to the surface of the structural member sample. By using the ultrasonic detector, ultrasonic detection is carried out on the inside of the structural member sample. By utilizing the difference in reflection signals when sound waves propagate in different media, cracks or water seepage channels inside the structural member concrete are identified. In this way, the water seepage points can be accurately located. Through this method, the water seepage condition of the structural member is detected. In combination with the use of a suction cup cover and internal water injection testing in the inclined holes, through this series of detection steps, the water seepage detection of the structural member sample in building construction can be achieved.

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 to 9 , the embodiment of the present invention provides a water seepage detection device for building construction, including a mounting base 1. A support platform 2 is installed above the mounting base 1. A support hollow column 3 is fixedly installed above the support platform 2, and the upper end of the support hollow column 3 is fixedly connected to a suction cup cover 4. A reinforcement base 34 is installed at the bottom of the support platform 2, and a bottom platform 35 is installed below the reinforcement base 34. A lead screw 36 passes through the interiors of the bottom platform 35, the reinforcement base 34, and the support platform 2. The outer edge of the bottom platform 35 is rotatably connected to a carbon steel support frame 37, and the inner wall of the carbon steel support frame 37 is rotatably connected to an adjusting rod 38. A nut moving platform 39 is slidably installed on the surface of the lead screw 36. The nut moving platform 39 forms a rotational connection with one end of the adjusting rod 38, and the end of the adjusting rod 38 away from the nut moving platform 39 forms a rotational connection with the carbon steel support frame 37; Specifically, a support hollow column 3 is installed on the support platform 2. The center inside the support hollow column 3 is a hollow structure, facilitating the penetration of the upper end of the lead screw 36. A reinforcement base 34 and a bottom platform 35 are installed at the bottom of the support platform 2. By means of the cooperation between the lead screw 36 and the nut moving platform 39, the nut moving platform 39 moves up and down along the lead screw 36. During the up and down movement of the nut moving platform 39, the adjusting rod 38 is pulled. Both ends of the adjusting rod 38 are rotatable structures with respect to the nut moving platform 39 and the carbon steel support frame 37 respectively. Thus, the carbon steel support frame 37 is pulled. When the nut moving platform 39 moves upward, the lower end of the adjusting rod 38 is pulled back, causing the carbon steel support frame 37 to rotate inward towards the vertical direction, thereby lifting the bottom platform 35 and pushing the suction cup cover 4 to fit the surface of the structural member. On the contrary, when the nut moving platform 39 moves downward, the lower end of the adjusting rod 38 is pushed outward, causing the carbon steel support frame 37 to rotate outward towards the horizontal direction, thereby lowering the bottom platform 35 and making the suction cup cover 4 away from the surface of the structural member. The fit degree between the suction cup cover 4 and the structural member is adjusted, and the upper and lower clamping of the structural member sample 5 is realized, facilitating the water seepage detection.

[0030] A silicone adsorption disc 42 is fixedly connected to the top edge of the suction cup cover 4. An air suction port 41 is arranged inside the suction cup cover 4, and one end of the air suction port 41 is connected to a vacuum air suction machine 40 through a pipeline. A water injection port 43 is arranged on the inner wall of the suction cup cover 4, and one end of the water injection port 43 is connected to a water pipe 6. A structural member sample 5 is arranged above the suction cup cover 4, and an inclined hole 7 is arranged on the surface of the structural member sample 5. The suction cup cover 4 is fixedly connected to the silicone adsorption disc 42, and the silicone adsorption disc 42 is in close contact with the surface of the structural member sample 5. The suction cup cover 4 is symmetrically arranged up and down with respect to the symmetry center line of the structural member sample 5, and the suction cup cover 4 is interconnected with the support platform 2 through the support hollow column 3; Specifically, an air suction port 41 is arranged inside the suction cup cover 4, and the air suction port 41 is connected to the vacuum air suction machine 40. The inside of the suction cup cover 4 is evacuated by the vacuum air suction machine 40. As the evacuation continues, the silicone adsorption disc 42 at the upper end of the suction cup cover 4 fits more and more tightly with the surface of the structural member sample 5. Water is injected into the inside of the suction cup cover 4 through the water pipe 6, enabling the water to come into contact with the surface of the structural member sample 5 and soaking the structural member sample 5. The water pipe 6 is connected to the water injection port, and the water pipe 6 is hermetically connected to the suction cup cover 4 through a sealing ring. Moreover, the water pipe 6 is connected to a water pump to drive the water into the inside of the suction cup cover 4. A check valve is used in combination on the water pipe 6 to prevent the water from flowing back and affecting the water seepage test result of the structural member sample 5. The suction cup cover 4 is arranged at the upper and lower ends of the structural member sample 5. In this way, the water seepage detection is carried out on both the front and back sides of the structural member simultaneously.

[0031] On both sides of the mounting base 1, there are rotatably mounted arm rods 8. In the middle of the arm rod 8, there is a rotatable connection with a rotating shaft 9. At the upper end of the arm rod 8, there is an ultrasonic detector 12 mounted. Above the ultrasonic detector 12, there is a connecting paste cylinder 13. Inside the paste cylinder 13, there is a resonance piece 14 mounted. On the left and right sides of the arm rod 8, there are rotatably connected second telescopic cylinders 11. On the outer side of the arm rod 8, there is a rotatably connected first telescopic cylinder 10. Between the lower end of the arm rod 8 and the mounting base 1, there is a rotatable connection formed. And between the arm rod 8 and the rotating shaft 9, there is a rotational structure formed. Between the outer side of the lower end of the arm rod 8 and the first telescopic cylinder 10, there is a rotatable connection formed. And between the two sides of the upper end of the arm rod 8 and the second telescopic cylinder 11, there is a rotatable connection formed; Specifically, by the mutual cooperation between the first telescopic cylinder 10 and the second telescopic cylinder 11, the arm rod 8 is pulled and adjusted. The first telescopic cylinder 10 is rotatably connected to the lower half of the arm rod 8, pulling the lower end of the arm rod 8 to rotate. The second telescopic cylinder 11 is rotatably connected to the upper half of the arm rod 8, and then pulls the upper half of the arm rod 8 and cooperates with the rotation of the rotating shaft 9 to adjust the extension angle of the arm rod 8, facilitating the adjustment of the detection height of the ultrasonic detector 12 at the upper end of the arm rod 8, making the ultrasonic detector 12 close to the outer wall of the structural member sample 5, and the paste cylinder 13 fitting the outer wall of the structural member sample 5. By performing ultrasonic detection on the inside of the structural member sample 5, using the difference in reflection signals when sound waves propagate in different media, the cracks or water seepage channels inside the structural member concrete are identified, so as to accurately locate the water seepage points.

[0032] A support platform 15 is fixedly installed on the outer edge of the support platform 2, and an adjusting arm 16 is rotatably connected to the upper end of the support platform 15. The upper end of the adjusting arm 16 is fixedly connected to a sliding rod 18, and an operation box 20 is slidably installed on the surface of the sliding rod 18. An adjusting lead screw 19 is installed on the outer side of the operation box 20. An adjusting cylinder 17 is rotatably connected to the outer side of the adjusting arm 16. A mounting rod 21 is slidably installed inside the operation box 20. A connecting cylinder 25 is fixedly arranged at the left end of the mounting rod 21. A tooth groove 26 is fixedly formed on the upper surface of the connecting cylinder 25, and a rotating gear 27 is meshingly installed above the tooth groove 26. A rotating shaft 28 is rotatably installed on the outer side of the connecting cylinder 25, and a node gear 29 is fixedly installed on the surface of the rotating shaft 28. An integrated slave gear 30 is connected to the surface of the node gear 29, and a driving gear 31 is meshingly installed on the outer side of the slave gear 30. A toothed belt 32 is arranged on the surface of the driving gear 31, and a driving gear 33 is installed below the toothed belt 32. A drill bit 24 is installed at the front end of the mounting rod 21, and a water seepage hole 44 is formed on the front surface of the mounting rod 21. A connecting pipe 23 is connected inside the water seepage hole 44, and an injection cylinder 22 is connected to the upper end of the connecting pipe 23. The adjusting arm 16 and the support platform 15 are of a rotating structure. The operation box 20 and the sliding rod 18 form a sliding structure. The mounting rod 21 and the rotating gear 27 are meshingly connected through the tooth groove on the surface, and the mounting rod 21 and the node gear 29 form a meshing connection structure. The node gears 29 are equidistantly distributed along the rotating shaft 28. The node gear 29 and the driving gear 31 form a meshing connection structure through the slave gear 30, and the driving gear 31 and the driving gear 33 are interconnected through the toothed belt 32; Specifically, inside the operation box 20, a connecting cylinder 25, a rotating shaft 28, and a rotating rod with a driving gear 31 are installed in parallel at the same time. The connecting cylinder 25 forms a sliding structure with the inside of the operation box 20. The rotating shaft 28 and the rotating rod with the driving gear 31 are rotatably connected to the inside of the operation box 20. The connecting cylinder 25 is fixedly connected to the mounting rod 21, and a set of gears is fixedly arranged at one end of the connecting cylinder 25. The connecting cylinder 25 forms a meshing structure with the node gear 29 through this set of gears. In this way, the driving device drives the gear 33 to rotate, drives the gear 33 to drive the driving gear 31 to rotate through the toothed belt transmission. The driving gear 31 and the driven gear 30 form a meshing structure. The driven gear 30 is fixedly connected to the node gear 29. Then, the node gear 29 drives the connecting cylinder 25 to rotate. The connecting cylinder 25 drives the mounting rod 21 to rotate, so as to realize the drilling of the surface of the structural member sample 5 by the drill bit 24 at the front end of the mounting rod 21. At the same time, the adjusting cylinder 17 is used to adjust the angle of the adjusting arm 16, and the adjusting arm 16 is pushed upward to rotate. As the adjusting arm 16 rotates upward continuously, the slide bar 18 on the adjusting arm 16 is inclined, and the operation box 20 installed on the slide bar 18 will also be inclined accordingly, so as to perform inclined drilling on the surface of the structural member. After the inclined hole 7 is drilled, the syringe 22 is used to inject water into the water seepage hole 44 through the connecting pipe 23. The water seepage hole 44 penetrates through the front end of the mounting rod 21, and then the water is poured into the inclined hole 7 through the connecting pipe 23. An electric push rod is installed inside the injection pipe, and the electric push rod is used to push the piston to inject water. The model of the electric push rod is DT-500-300. The water is poured into the inclined hole 7 to soak the inside of the structural member, and the water will conduct a water seepage test from the inside to the outside of the structural member, so as to avoid the situation of water seepage and delamination between the inside and the outside of the structural member. When performing water seepage detection from the inside to the outside of the structural member, it is beneficial to improve the comprehensiveness of the detection direction. A circular tooth groove 26 is arranged on the surface of the connecting cylinder 25, and the tooth groove 26 is engaged with the rotating gear 27. The driving device drives the rotating gear 27 to rotate, so as to adjust the extended length of the mounting rod 21. The teeth on the surface of the rotating gear 27 are parallel to the tooth groove 26, so as not to affect the rotation of the connecting cylinder 25 driving the mounting rod 21. The mounting rod 21 is pushed out of the operation box 20, so that the drill bit 24 is closer to the surface of the structural member sample 5, which is beneficial for the drill bit 24 to drill. At the same time, the adjusting lead screw 19 is adjusted to drive the operation box 20 to slide along the slide bar 18, and cooperate with the extension of the drill bit 24 to approach the structural member sample 5.

[0033] When using the present invention, firstly, the height of the suction cup cover 4 is adjusted by the cooperation of the screw rod 36 and the nut moving platform 39, so that the suction cup cover 4 can be located directly above and directly below the structural member sample 5, and the nut moving platform 39 moves upward to pull the lower end of the adjusting rod 38 back, so that the carbon steel support frame 37 rotates inwardly and tends to be vertical, thereby lifting the bottom platform 35, pushing the suction cup cover 4 to fit the surface of the structural member, and the nut moving platform 39 below the upper and lower clamping of the structural member sample 5 moves downward, and the movement direction at the top is opposite, and the downward movement can push the suction cup cover 4 above, and then start the vacuum suction machine 40, and evacuate the inside of the suction cup cover 4 through the suction port 41, so that the silicone adsorption plate 42 is closely fitted with the surface of the structural member sample 5, and then start the water pump, and inject water into the inside of the suction cup cover 4 through the water pipe 6, so as to contact and soak the structural member sample 5, and then start the driving gear 33, and drive the driving gear 31 to rotate through the toothed belt 32, and the driving gear 31 drives the slave gear 30 to rotate, and the slave gear 30 drives the node gear 29 rotates, the node gear 29 drives the connecting tube 25 to rotate, and the connecting tube 25 drives the installation rod 21 to rotate, so that the drill bit 24 at the front end of the installation rod 21 drills holes on the surface of the structural member sample 5, and at the same time, the adjusting cylinder 17 is used to adjust the angle of the adjusting arm 16 to perform inclined drilling on the surface of the structural member. After the inclined hole 7 is drilled, the electric push rod inside the injection cylinder 22 is started, and the piston is pushed to pour water into the inclined hole 7 through the connecting pipe 23, and the water seepage test is performed from the inside to the outside of the structural member, so as to avoid the water seepage stratification between the inside and the outside of the structural member, and improve the comprehensiveness of the detection direction during the detection. After the set time of contact immersion is reached, the ultrasonic detector 12 is started to perform ultrasonic detection on the inside of the structural member sample 5, and the difference in the reflected signal when the sound wave propagates in different media is used to identify the cracks or water seepage channels inside the concrete of the structural member, and accurately locate the water seepage point. After the detection is completed, all equipment is turned off, the structural member sample 5 is moved out of the detection area, and the water seepage detection of the structural member sample 5 for construction is completed.
