Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a rapid testing device for the waterproofing quality of basements in building construction. Background Technology

[0002] Waterproofing is a waterproofing project that ensures the structure of a building (structure) is not affected by water and the interior space is not damaged by water. Basements in shantytown renovation and resettlement projects are prone to water seepage problems, so waterproofing treatment is necessary for the basement walls.

[0003] Currently, the side walls between the load-bearing beams / columns of the basement are the key areas for water seepage, requiring focused waterproofing treatment. After waterproofing, the quality of the waterproofing needs to be tested to ensure its effectiveness. However, the side walls of basements in shantytown renovation and resettlement projects are mostly single-sided walls, meaning that common methods of penetrating water spraying for seepage detection are difficult to implement. For the waterproofing quality testing of such single-sided walls, the usual method is to directly spray water into the inner wall to detect seepage, followed by manual observation of the wall's seepage. This testing method has the disadvantages of being highly subjective, having large errors, and requiring long periods of observation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a rapid testing device for the waterproofing quality of basement in building construction, which has a short testing cycle and high accuracy.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A rapid testing device for waterproofing quality of basement in building construction includes a positioning cylinder, which is placed on a wall and forms a closed cavity with the wall; a stopper disc is provided inside the positioning cylinder, and the stopper disc and the inner wall of the positioning cylinder are sealed together. The stopper disc is driven to move axially along the positioning cylinder by a pressure shaft; a pressure sensor and a humidity sensor are provided on the side of the stopper disc facing the wall. The pressure sensor is used to measure the air pressure in the cavity between the stopper disc and the wall, and the humidity sensor is used to measure the humidity in the cavity between the stopper disc and the wall.

[0006] One end of the positioning cylinder is a blind end and the other end is open, and a sealing ring is provided on the end face of the opening of the positioning cylinder.

[0007] The pressure plate has a mounting groove on one side, and the pressure sensor and humidity sensor are fixedly installed in the mounting groove; the pressure shaft has a wire channel that connects to the mounting groove, and the outer wall of the pressure shaft has a wire hole located outside the positioning cylinder and connected to the wire channel.

[0008] The top of the positioning cylinder is welded with a grooved frame, and a lead screw is threaded through and connected to the top of the grooved frame. The bottom of the lead screw is rotatably connected to the top of the pressure shaft.

[0009] A force-applying rod is welded to the top of the lead screw.

[0010] The outer wall of the positioning cylinder is symmetrically fixed with ear plates, and a screw is threaded through and connected to the ear plates. The screw is parallel to the axis of the positioning cylinder; a suction cup is rotatably connected to the bottom of the screw.

[0011] A screw is welded to the top of the screw.

[0012] This utility model provides a rapid testing device for the waterproofing quality of basements in building construction, which has the following technical advantages: 1) By setting a positioning cylinder and installing an axially movable stopper inside the positioning cylinder, when the opening of the positioning cylinder is in contact with the wall, the air pressure inside the positioning cylinder increases as the stopper moves. At this time, the wall is subjected to extrusion force. Then, a pressure sensor and a humidity sensor are installed on the side of the stopper facing the wall to obtain the magnitude of the extrusion force on the wall, which is convenient for simulating the groundwater pressure environment. The change in humidity inside the positioning cylinder detected by the humidity sensor can be used to determine the waterproof quality of the wall. This detection method has the advantages of short cycle and high accuracy.

[0013] 2) By setting suction cups on the outside of the positioning cylinder to press the positioning cylinder against the wall and screws to adjust the pressing force, the mating surface between the positioning cylinder and the wall is sealed, eliminating the need for manual pressing and saving effort.

[0016] Figure 3 This is a partial main sectional view of the present invention.

[0017] Figure 4 This is a circuit block diagram of the present invention.

[0018] In the diagram: positioning cylinder 1, slotted frame 11, ear plate 12, sealing ring 2, pressure shaft 3, wire channel 31, wire hole 32, plug plate 4, mounting slot 41, display 5, lead screw 6, force rod 61, screw 7, turning plate 71, suction cup 8, pressure sensor 9, humidity sensor 101. Detailed Implementation

[0019] like Figures 1-3As shown, a rapid testing device for waterproofing quality of basement in building construction includes a positioning cylinder 1. One end of the positioning cylinder 1 is a blind end and the other end is open. A sealing ring 2 is provided on the open end face of the positioning cylinder 1. When in use, the open end of the positioning cylinder 1 is attached to the wall to be tested. The sealing ring 2 seals the joint surface between the positioning cylinder 1 and the wall. At this time, the positioning cylinder 1 and the wall form a closed cavity.

[0020] like Figure 1 As shown, a pressure shaft 3 that can slide axially is provided through the blind end of the positioning cylinder 1. One end of the pressure shaft 3 is fixedly connected to a stopper 4 located inside the positioning cylinder 1. The stopper 4 and the inner wall of the positioning cylinder 1 are in a sealed sliding fit. In specific implementation, a sealing ring is sleeved on the outside of the stopper 4. The pressure shaft 3 provides driving force for the axial movement of the stopper 4. When the stopper 4 moves towards the wall, the air pressure between the wall and the stopper 4 increases.

[0021] like Figure 2 As shown, a pressure sensor 9 and a humidity sensor 101 are installed on the side of the stopper disc 4 facing the opening of the positioning cylinder 1. The function of the pressure sensor 9 (model GDY1122) is to monitor the air pressure in the cavity between the stopper disc 4 and the wall in real time, and the function of the humidity sensor 101 (model Si7021) is to monitor the humidity of the air in the cavity between the stopper disc 4 and the wall. If the humidity remains unchanged or changes only slightly during the pressure holding period (e.g., 2 minutes), it indicates that the waterproof quality is high; otherwise, the waterproof quality is poor.

[0022] It should be noted that the pressure in the cavity between the stopper 4 and the wall depends on the actual situation, such as the pressure of the water body corresponding to the depth of the basement. Here, the water body refers to the squeezing force of the water body on the wall when the wall is immersed in water.

[0023] like Figure 1 As shown, a display 5 is further fixedly connected to the top of the positioning cylinder 1. The display 5 is electrically connected to the pressure sensor 9 and the humidity sensor 101. The display 5 is used to display the values ​​measured by the pressure sensor 9 and the humidity sensor 101. In use, a battery pack can be installed outside the positioning cylinder 1 to supply power to the display 5, the pressure sensor 9, and the humidity sensor 101.

[0024] like Figure 2As shown, preferably, a mounting groove 41 is provided on one side of the stopper 4. The pressure sensor 9 and the humidity sensor 101 are fixedly installed in the mounting groove 41. The pressure sensor 9 is a common air pressure sensor. A wire channel 31 is provided inside the pressure shaft 3, which connects to the mounting groove 41. The wire channel 31 is used to accommodate the wires on the pressure sensor 9 and the humidity sensor 101. A wire through hole 32 is provided on the outer wall of the pressure shaft 3, located outside the positioning cylinder 1 and connecting to the wire channel 31. The wire passes through the wire through hole 32 and is connected to the display 5 and the battery pack. Before use, sealant needs to be injected into the wire through hole 32 to prevent leakage.

[0025] like Figure 1 As shown, preferably, the end of the positioning cylinder 1 connected to the sealing ring 2 is a square sleeve structure. The width of the square sleeve is greater than the outer diameter of the positioning cylinder 1. The square sleeve structure makes the area detected by this device on the wall form a square area, which facilitates continuous displacement and coverage detection of the wall. In other words, there are no dead corners between adjacent detection areas. This setting can reduce the number of displacement detections of this device as a whole and improve the detection efficiency.

[0026] like Figure 1 As shown, preferably, a grooved frame 11 is welded to the top of the positioning cylinder 1, and a lead screw 6 is threadedly connected to the top of the grooved frame 11. The bottom of the lead screw 6 is rotatably connected to the top of the pressure shaft 3. When the lead screw 6 rotates, it can move axially, thereby applying an axial driving force to the pressure shaft 3. In use, the number of rotations of the lead screw 6 can be manually controlled according to the pressure value measured by the pressure sensor 9. A force-applying rod 61 can be welded to the top of the lead screw 6. The force-applying rod 61 is an operating component that allows manual hand-holding and twisting of the lead screw 6.

[0027] like Figure 1 As shown, preferably, two symmetrically distributed ear plates 12 are fixedly connected to the outer peripheral wall of the positioning cylinder 1. A screw 7 parallel to the axis of the positioning cylinder 1 is threaded through and connected to one side of the ear plate 12. A suction cup 8 is rotatably connected to the bottom of the screw 7. The function of the suction cup 8 is to fix the positioning cylinder 1 to the wall. The function of the screw 7 is to adjust the squeezing force of the positioning cylinder 1 on the wall, thereby ensuring the sealing between the positioning cylinder 1 and the wall. This setting eliminates the need for the testing personnel to continuously position the cylinder 1 to ensure the sealing, thus saving more effort.

[0028] During use, a rotating disc 71 can be welded to the top of the screw 7. The rotating disc 71 is a handheld component for manually controlling the rotation of the screw 7. In order to improve the sealing between the suction cup 8 and the wall, the suction cup 8 can be designed with a structure incorporating silicone material on its outer edge to adapt to wall surfaces with poor flatness.

[0029] It should be noted that this device can also be used to test the waterproofing quality of the basement floor. Since the floor is level, the waterproofing material will block the seepage and wind suction by its own weight, and the quality of the waterproofing treatment is usually good. Therefore, when testing the waterproofing quality of the floor, this device can be used to randomly select some areas or areas with potential problems for testing.

[0030] Working principle and process: 1) When using, first attach the suction cup 8 to the wall, then rotate the screw 7 by turning the screw plate 71. At this time, the ear plate 12 will drive the positioning cylinder 1 to approach the wall. When the sealing ring 2 presses against the wall, stop rotating the screw 7.

[0031] 2) Then, manually rotate the force rod 61. The lead screw 6 moves axially and drives the pressure shaft 3 to move axially, which in turn drives the stopper disc 4 to move towards the wall. The air pressure between the stopper disc 4 and the wall increases. The pressure sensor 9 reads the pressure value. When the pressure value reaches the required value, stop rotating the lead screw 6.

[0032] 3) Finally, maintain the pressure for several minutes, and then observe the humidity value displayed on monitor 5 and the amount of change. When the humidity does not change or changes only slightly, it indicates that the wall waterproofing quality is high.
