Abstract

The present invention discloses a water seepage detection device for building construction, including a mounting base. Above the support platform, a support hollow column is fixedly installed, and the upper end of the support hollow column is fixedly connected to a suction cup cover. The top edge of the suction cup cover is fixedly connected to a silicone adsorption disc. An air inlet is arranged inside the suction cup cover, and one end of the air inlet is connected to a vacuum suction machine through a pipeline. A water injection port is arranged on the inner wall of the suction cup cover, and one end of the water injection port is connected to a water pipe. Above the suction cup cover, there is a structural member sample; a water pipe is connected to the adsorption cover, and water is injected into the suction cup cover through the water pipe. After water is injected into the suction cup cover, the water will adhere to 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 water seepage test is carried out synchronously on the upper and lower adsorption covers, and the water seepage conditions on the front and back surfaces of the structural member are detected at the same time, improving the multi-facetedness of the detection.

Description

Technical Field

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

[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, the convenience is higher and it is also relatively simple. Therefore, when the structural components enter the construction site, the water seepage detection of the structural components is carried out in advance.

[0003] A Chinese patent discloses a water seepage detection device for bridge construction (publication number CN117825234A). The detection device includes a protective housing. A servo motor is arranged at the top end inside the protective housing, and a lead screw is fixed to the output end of the servo motor. The lead screw is rotatably connected to the upper partition of the protective housing through a bearing. One end of the lead screw extending below the partition is threadedly sleeved with an adjusting sleeve. In the present invention, the lead screw and the sleeve can enable the drill barrel to operate without manual control during use, ensuring the coring accuracy. At the same time, by the method of coring first and then storing water for detection, 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 coring process, resulting in unclear imaging and thus low detection accuracy, is solved. The accuracy of the detection device is improved, and the influence of temperature on the detection accuracy during coring is avoided.

[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, resulting in a relatively large degree of damage. Moreover, once problems are detected, on-site demolition is required, and the subsequent treatment procedures are relatively complex. In addition, the single-sided and unidirectional 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 a prefabricated structural member, and after being transported to the construction site, the structural members are assembled. In this way, the construction efficiency is higher. Before the structural member arrives at 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, so as to control the construction quality. At present, when detecting the water seepage of the structural member, the water seepage 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 insufficiently comprehensive detection direction during the detection, and not considering the water seepage test detection of the structural member under different conditions.

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

A drill bit is installed at the front end of the installation rod, and a water seepage hole is opened on the front end surface of the installation rod. A connecting pipe is connected inside the water seepage hole, and the upper end of the connecting pipe is connected with an injection cylinder.

[0011] As an implementation manner of the present invention, the suction cup cover and the silicone adsorption disc are fixedly connected, and the silicone adsorption disc is closely attached to the surface of the structural member sample.

[0012] 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.

[0013] 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.

[0014] As an implementation manner of the present invention, the mounting rod is meshed with the rotating gear through the tooth alveoli on the surface, and a meshing connection structure is formed between the mounting rod and the node gear, and the node gears are equidistantly distributed and installed along the rotating shaft.

[0017] As an implementation manner 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.

[0018] As an implementation manner of the present invention, the outer edge of the bottom platform is rotatably connected to a carbon steel support frame, and an adjusting rod is rotatably connected to the inner wall of the carbon steel support frame. A nut moving platform is slidably installed on the surface of the lead screw.

[0019] As an implementation manner 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.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 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 suction port is provided inside the suction cup cover, and the air suction port is interconnected with a vacuum air suction machine through a pipeline. The vacuum air suction machine is used to evacuate the inside of the suction cup cover into a vacuum environment. A silicone adsorption disk is integrally provided at the upper edge of the suction cup cover, and the silicone adsorption disk fits the upper and lower ends of the structural member sample. After being evacuated into a vacuum, the silicone adsorption disk 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, so that the surface of the structural member is always in contact with water, and then the surface of the structural member sample is soaked. The suction cup covers are provided on the upper and lower sides to synchronously conduct a water seepage test on the structural member sample from top to bottom. 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 bottom to top. Therefore, single-sided detection is not comprehensive enough. By synchronously conducting a water seepage test using the upper and lower adsorption covers, the water seepage conditions of the front and back of the structural member can be detected simultaneously, improving the comprehensiveness of the detection;

[0022] 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, so as to conduct an inside-out detection of the structural member. 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 water is poured into the inclined holes through the water seepage hole to soak the inside of the structural member. Water will conduct an inside-out water seepage test from the inside of the structural member, thus avoiding the situation of water seepage stratification between the inside and outside of the structural member, resulting in a qualified surface water seepage test of the structural member, but a relatively serious inside-out water seepage situation inside. In this way, the quality of the structural member will still have problems. When conducting an inside-out water seepage detection on the inside of the structural member, it is beneficial to improve the comprehensiveness of the detection direction during detection, considering the water seepage test detection of the structural member under different conditions and improving the detection effectiveness;

[0023] 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.

Detailed implementation manners

[0034] 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.

[0035] Please refer to Figures 1 to 9 , an 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 a suction cup cover 4 is fixedly connected to the upper end of the support hollow column 3. 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 penetrates 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 and one end of the adjusting rod 38 form a rotational connection, and the end of the adjusting rod 38 away from the nut moving platform 39 and the carbon steel support frame 37 form a rotational connection;

[0036] 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 using the cooperation of 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 between the nut moving platform 39 and the carbon steel support frame 37, thereby pulling the carbon steel support frame 37. 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, 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, 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 structural member sample 5 is clamped tightly up and down, facilitating the water seepage detection.

[0037] The top edge of the suction cup cover 4 is fixedly connected with a silicone suction disc 42. An air inlet 41 is arranged inside the suction cup cover 4, and one end of the air inlet 41 is connected with a vacuum 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 with 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 with the silicone suction disc 42, and the silicone suction disc 42 is closely attached to 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 connected with the support platform 2 through the support hollow column 3;

[0038] Specifically, an air inlet 41 is arranged inside the suction cup cover 4, and the air inlet 41 is connected with the vacuum suction machine 40. The inside of the suction cup cover 4 is evacuated by the vacuum suction machine 40. As the evacuation continues, the silicone suction 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, so that the water contacts the surface of the structural member sample 5, realizing the immersion of the structural member sample 5. The water pipe 6 is connected with the water injection port, and the water pipe 6 is hermetically connected with the suction cup cover 4 through a sealing ring. And the water pipe 6 is connected with a water pump to drive water into the inside of the suction cup cover 4. And 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 the front and back surfaces of the structural member simultaneously.

[0039] 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, and above the ultrasonic detector 12, there is a sticker cylinder 13 connected. Inside the sticker cylinder 13, there is a resonance piece 14 mounted. On the left and right sides of the arm rod 8, there are rotatable connections with a second telescopic cylinder 11. On the outer side of the arm rod 8, there is a rotatable connection with a 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 rotating 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 upper end sides of the arm rod 8 and the second telescopic cylinder 11, there is a rotatable connection formed;

[0040] 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 sticker 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, thus accurately positioning the water seepage points.

[0041] A support platform 15 is fixedly installed on the outer edge of the support platform 2, and an adjustment arm 16 is rotatably connected to the upper end of the support platform 15. The upper end of the adjustment 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 adjustment lead screw 19 is installed on the outside of the operation box 20, and an adjustment cylinder 17 is rotatably connected to the outside of the adjustment arm 16. An installation rod 21 is slidably installed inside the operation box 20, and a connection cylinder 25 is fixedly arranged at the left end of the installation rod 21. A tooth groove 26 is fixedly opened on the upper surface of the connection cylinder 25, and a rotating gear 27 is meshingly installed above the tooth groove 26. A rotating shaft 28 is rotatably installed on the outside of the connection cylinder 25, and a node gear 29 is fixedly installed on the surface of the rotating shaft 28. A slave gear 30 is integrally connected to the surface of the node gear 29, and a driving gear 31 is meshingly installed on the outside 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 inside of the toothed belt 32. A drill bit 24 is installed at the front end of the installation rod 21, and a water seepage hole 44 is opened on the front surface of the installation 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 adjustment 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 installation rod 21 is meshingly connected with the rotating gear 27 through the tooth alveolar groove on the surface, and the installation rod 21 and the node gear 29 form a meshing connection structure. The node gears 29 are equidistantly distributed and installed along the rotating shaft 28. The node gear 29 is meshingly connected with the driving gear 31 through the slave gear 30, and the driving gear 31 is interconnected with the driving gear 33 through the toothed belt 32;

[0042] Specifically, inside the operation box 20, a connecting cylinder 25, a rotating shaft 28, and a rotating rod installed 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 installed with the driving gear 31 form a rotating connection with 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 connecting cylinder 25 is driven to rotate by the node gear 29. The connecting cylinder 25 drives the mounting rod 21 to rotate. Thus, the drill bit 24 at the front end of the mounting rod 21 drills holes in the surface of the structural member sample 5. At the same time, the adjusting cylinder 17 is used to adjust the angle of the adjusting arm 16, pushing the adjusting arm 16 upward to rotate. As the adjusting arm 16 continuously rotates upward, the sliding rod 18 on the adjusting arm 16 tilts, and the operation box 20 installed on the sliding rod 18 also tilts accordingly, so as to perform inclined drilling on the surface of the structural member. After the inclined hole 7 is drilled, the injection cylinder 22 injects water into the water seepage hole 44 through the connecting pipe 23. The water seepage hole 44 penetrates the front end of the mounting rod 21. Then, water is poured into the inclined hole 7 through the connecting pipe 23. An electric push rod is installed inside the injection pipe. The electric push rod is used to push the piston, and then the water is injected. 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. The water will perform a water seepage test from the inside to the outside of the structural member, thus avoiding the situation of water seepage 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. An annular tooth groove 26 is arranged on the surface of the connecting cylinder 25. The tooth groove 26 is engaged with the rotating gear 27. The driving device drives the rotating gear 27 to rotate, and then adjusts 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, avoiding affecting the rotation of the connecting cylinder 25 driving the mounting rod 21. The mounting rod 21 is pushed out of the operation box 20, making the drill bit 24 closer to the surface of the structural member sample 5, which is beneficial for the drill bit 24 to drill holes. At the same time, the adjusting lead screw 19 is adjusted to drive the operation box 20 to slide along the sliding rod 18, and cooperate with the extension of the drill bit 24 to approach the structural member sample 5.

[0043] 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.
