Description

Technical Field

[0001] This utility model specifically relates to a water erosion inspection device for basement floor slabs, belonging to the field of building inspection. Background Technology

[0002] In modern buildings, basements are often situated in environments with high groundwater levels, where the interface between the concrete slab and the underlying subbase is continuously soaked by capillary water and stagnant water. Moisture erosion of the structure often begins in the relatively porous and low-strength subbase, then gradually migrates upwards along construction cold joints, structural joints, or micro-cracks. Due to its porous nature and low density, the subbase often becomes the first area to become damp and continuously retain water. The process of moisture spreading laterally within the subbase can last for months, during which time there are often no signs of leakage on the slab surface. By the time damp stains or standing water appear on the slab surface, the internal reinforcing steel has often de-passivated, and the alkaline environment of the concrete has been damaged, leading to a severe decrease in structural durability and a significant reduction in service life.

[0003] Currently, detection technologies for this type of hidden water erosion still have significant limitations. On the one hand, the absence of water stains on the exterior of the structure does not necessarily mean that the internal subfloor is dry. Conventional infrared thermography or conductivity testing responds very weakly to microcracks less than 0.2 mm wide and to subfloor layers in a saturated state, making early and effective identification difficult. On the other hand, existing electronic sensor monitoring methods generally rely on power and signal cables, but the high humidity and frequent electromagnetic interference in basement environments result in poor long-term equipment stability and a high failure rate, making long-term reliable monitoring of hidden water erosion difficult.

[0004] Therefore, there is an urgent need to develop a new detection technology that can identify moisture inside the base plate at an early stage, in order to make up for the shortcomings of existing methods in monitoring hidden water damage. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a basement floor water erosion inspection device is provided to solve the above problems.

[0006] A basement floor water erosion inspection device includes a transparent PC container, a breathable cap, a multi-layer dyed component, and a positioning component. The bottom of the transparent PC container is fitted with a breathable cap, the transparent PC container contains a multi-layer dyed component, and the transparent PC container is fitted with a positioning component. The multi-layered dyed part includes a mesh tube, a bottom microcapsule membrane, a middle microcapsule membrane, a top microcapsule membrane, a handle, a green drying dye, a yellow drying dye, and a red drying dye. The mesh tube is placed inside a transparent PC container, and a handle is provided at the open end of the mesh tube. The bottom microcapsule membrane, the middle microcapsule membrane, and the top microcapsule membrane are arranged sequentially inside the mesh tube. The bottom microcapsule membrane contains the green drying dye, the middle microcapsule membrane contains the yellow drying dye, and the top microcapsule membrane contains the red drying dye.

[0007] As a preferred embodiment: the transparent PC container includes a transparent PC cover, a transparent PC cylinder, and a rubber ring. A mesh cylinder is provided inside the transparent PC cylinder. Multiple strip holes are machined along the circumference of the sealing end of the transparent PC cylinder. A vent cap is fitted onto the sealing end of the transparent PC cylinder and completely covers the multiple strip holes. An internal thread groove is machined on the inner wall of the open end of the transparent PC cylinder. An external thread is provided on the transparent PC cover. The external thread is threaded to the internal thread groove. An arc groove is machined along the circumference of the external thread. A rubber ring is fitted inside the arc groove. A diffuse reflection ring is machined along the circumference of the exposed end face of the transparent PC cover. A transverse screwing component is provided on the exposed end face of the transparent PC cover.

[0008] As a preferred option, the inner wall of the transparent PC tube is processed with three sets of stepped grooves. The three sets of stepped grooves are distributed circumferentially along the inner wall of the tube and are distributed in a stepped manner along the axial direction, forming a stepped sequence from low to high. The three sets of stepped grooves correspond to the positions of green drying dye, yellow drying dye and red drying dye, respectively.

[0009] As a preferred option: each set of stepped grooves includes three sub-grooves, which are distributed circumferentially along the inner wall of the pipe and in a stepped manner along the axial direction, forming a stepped sequence from low to high.

[0010] As a preferred embodiment: a positioning component is fitted onto the transparent PC cylinder. The positioning component includes a collar, a T-ring, multiple barbs, multiple sliding parts, and multiple hanging rings. Multiple barbs are provided on the upper end of the collar along its circumference, and a T-ring is fitted on the lower end of the collar along its circumference. Multiple sliding parts are slidably arranged on the T-ring along its circumference, and each sliding part is provided with a hanging ring.

[0011] The beneficial effects of this utility model are as follows: This invention divides a transparent PC container into three areas using green, yellow, and red drying dyes. As the water level rises, the dyes in the corresponding areas dissolve, forming colored water columns. By observing the color of the transparent PC container, the water level can be directly determined, enabling early identification of the water level. This invention also uses positioning components to firmly anchor the device within the base plate, avoiding buoyancy and lateral displacement during concrete pouring and vibration, thus ensuring accurate device positioning.

Detailed Implementation

[0014] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0015] Specific implementation method one: Combining Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9This embodiment describes a basement floor water erosion inspection device, which includes a transparent PC container 1, a breathable cap 2, a multi-layer dyed component 3, and a positioning component 4. The bottom of the transparent PC container 1 is fitted with the breathable cap 2, the transparent PC container 1 is provided with a multi-layer dyed component 3, and the transparent PC container 1 is fitted with the positioning component 4. The multi-layer dyed component 3 includes a mesh tube 3-1, a bottom microcapsule membrane 3-2, a middle microcapsule membrane 3-3, a top microcapsule membrane 3-4, a handle 3-5, a green drying dye 3-6, a yellow drying dye 3-7, and a red drying dye 3-8. The mesh tube 3-1 is placed inside a transparent PC container 1. A handle 3-5 is provided at the open end of the mesh tube 3-1. The bottom microcapsule membrane 3-2, the middle microcapsule membrane 3-3, and the top microcapsule membrane 3-4 are arranged sequentially inside the mesh tube 3-1. The bottom microcapsule membrane 3-2 contains the green drying dye 3-6, the middle microcapsule membrane 3-3 contains the yellow drying dye 3-7, and the top microcapsule membrane 3-4 contains the red drying dye 3-8.

[0016] The bottom microcapsule membrane 3-2, the middle microcapsule membrane 3-3, and the top microcapsule membrane 3-4 are all made of water-soluble material, preferably ethyl cellulose. The bottom microcapsule membrane 3-2, the middle microcapsule membrane 3-3, and the top microcapsule membrane 3-4 respectively seal the corresponding green drying dye 3-6, yellow drying dye 3-7, and red drying dye 3-8 to prevent condensation from wetting the green drying dye 3-6, yellow drying dye 3-7, or red drying dye 3-8, which could lead to misjudgment by the observer.

[0017] When the water level stabilizes and the bottom microcapsule membrane 3-2 is submerged for an extended period, the membrane gradually dissolves, and the green drying dye 3-6 is soaked in water, resulting in a green color inside the transparent PC container 1. When an external light source shines from the top of the transparent PC container 1, the highly transparent material refracts the green color upwards, allowing the observer to directly see the green ring, thus confirming that the water level has reached the bottom layer. Similarly, as the water level continues to rise to the middle microcapsule membrane 3-3 or the upper microcapsule membrane 3-4, the membranes dissolve sequentially, and the yellow or red drying dye is soaked in water, resulting in a yellow or red color inside the container, thus achieving a continuous, graded, and intuitive display of low, medium, and high water levels.

[0018] After the water in the bottom plate 5 is treated and the water level drops to the normal range, the transparent PC container 1 can be opened. The mesh tube 3-1 can be taken out through the handle 3-5. After replacing the bottom microcapsule membrane 3-2, the middle microcapsule membrane 3-3, and the top microcapsule membrane 3-4 in the mesh tube 3-1, it can be put back into the transparent PC container 1 to achieve rapid replacement of the green drying dye 3-6, the yellow drying dye 3-7, and the red drying dye 3-8.

[0019] The vent cap 2 is made of sintered bronze, which has the characteristics of being permeable to water but not to air. During the pouring of the base plate 5, it can effectively block cement mortar from entering the bottom opening of the transparent PC container 1, preventing the bottom opening of the transparent PC container 1 from being blocked by the mortar, thereby ensuring that groundwater can smoothly seep into the container.

[0020] Specific Implementation Method Two: This implementation method is a further limitation of Specific Implementation Method One. The transparent PC container 1 includes a transparent PC cover 1-1, a transparent PC cylinder 1-2, and a rubber ring 1-3. A mesh cylinder 3-1 is provided inside the transparent PC cylinder 1-2. Multiple strip holes 1-21 are machined along the circumference of the sealing end of the transparent PC cylinder 1-2. A vent cap 2 is fitted onto the sealing end of the transparent PC cylinder 1-2 and completely covers the multiple strip holes 1-21. An internal thread groove 1-22 is machined on the inner wall of the open end of the transparent PC cylinder 1-2. An external thread 1-11 is provided on the transparent PC cover 1-1. The external thread 1-11 is threadedly connected to the internal thread groove 1-22. An arc groove 1-13 is machined along the circumference of the external thread 1-11. A rubber ring 1-3 is fitted inside the arc groove 1-13. A diffuse reflection ring 1-12 is machined along the circumference of the exposed end face of the transparent PC cover 1-1. A transverse screwing part 1-14 is provided on the exposed end face of the transparent PC cover 1-1.

[0021] The rubber ring 1-3 effectively seals the gap between the transparent PC cover 1-1 and the transparent PC cylinder 1-2, ensuring the initial sealing performance of the transparent PC cover 1-1 and the transparent PC cylinder 1-2. Water enters the transparent PC cylinder 1-2 through multiple strip holes 1-21, soaking the multi-layer dyed parts 3. Thus, depending on the water level, the transparent PC cylinder 1-2 is dyed with different colors. Since both the transparent PC cover 1-1 and the transparent PC cylinder 1-2 are transparent, when light shines through them, the color of the dye in the transparent PC cylinder 1-2 is refracted onto the transparent PC cover 1-1, allowing for a direct observation of the water level and thus determining the water level position on the bottom plate 5. The exposed end face of the transparent PC cover 1-1 is machined with a diffuse reflection ring 1-12 along its circumference. The diffuse reflection ring 1-12 diffuses the color reflected by the light, improving the observation effect. The transparent PC cover 1-1 can be rotated by the transverse screw 1-14, thereby opening the transparent PC cover 1-1 and facilitating the removal and replacement of the multi-layer dyed parts 3 as a whole.

[0022] Specific Implementation Method 3: This implementation method is a further limitation of Specific Implementation Method 1 or 2. The inner wall of the transparent PC cylinder 1-2 is processed with three sets of stepped grooves 1-23. The three sets of stepped grooves 1-23 are distributed circumferentially along the inner wall of the tube and are distributed in a stepped manner along the axial direction, forming a stepped sequence from low to high. The three sets of stepped grooves 1-23 correspond to the positions of green drying dye 3-6, yellow drying dye 3-7 and red drying dye 3-8, respectively.

[0023] Green drying dye 3-6, yellow drying dye 3-7, and red drying dye 3-8 correspond to the three sets of stepped grooves 1-23, respectively. Viewed from above the transparent PC cover 1-1, the three sets of stepped grooves 1-23 do not overlap, and the green, yellow, and red coloring areas are arranged sequentially from low to high. Observers can intuitively determine the specific area where the water level falls without shifting their line of sight, achieving a rapid water level assessment.

[0024] Specific Implementation Method Four: This implementation method is a further limitation of Specific Implementation Method One, Two or Three. Each set of stepped grooves 1-23 includes three sub-grooves 1-23-1. The three sub-grooves 1-23-1 are distributed circumferentially along the inner wall of the pipe and are distributed in a stepped manner along the axial direction, forming a stepped sequence from low to high.

[0025] The three sub-tanks 1-23-1 are arranged in a stepped pattern, further subdividing the corresponding dyeing area into low, medium, and high levels. As the water reaches different heights, the dyed water sequentially enters the corresponding sub-tank 1-23-1. Looking down from the transparent PC cover 1-1, one can intuitively determine which level the water level is at, achieving a rapid water level assessment. Because the dyed water enters the sub-tank 1-23-1, when the light source refracts the color upwards, the color in the corresponding observation area is more concentrated, enhancing the local observation effect.

[0026] Specific Implementation Method 5: This implementation method further defines Specific Implementation Methods 1, 2, 3, or 4. A positioning component 4 is fitted onto the transparent PC cylinder 1-2. The positioning component 4 includes a collar 4-1, a T-shaped ring 4-3, multiple barbs 4-2, multiple sliding parts 4-4, and multiple hanging rings 4-5. Multiple barbs 4-2 are provided on the upper end of the collar 4-1 along its circumference. A T-shaped ring 4-3 is fitted on the lower end of the collar 4-1 along its circumference. Multiple sliding parts 4-4 are slidably arranged on the T-shaped ring 4-3 along its circumference. Each sliding part 4-4 is provided with a hanging ring 4-5.

[0027] During the pouring of the base plate 5, multiple barbs 4-2 are simultaneously embedded in the concrete, significantly increasing the bonding force between the device and the base plate 5, effectively preventing loosening or detachment after pouring; multiple sliding parts 4-4 can slide freely on the T-shaped ring 4-3, allowing the hanging rings 4-5 on them to move to the required position, facilitating the binding straps to fix the entire device to the steel reinforcement frame of the base plate 5 through the multiple hanging rings 4-5, thereby ensuring a firm installation and accurate positioning, and preventing the device from shifting due to the impact of mortar during pouring.

[0028] Working principle: The vent cap 2 can be made of sintered bronze, which has the characteristics of being permeable to water but not to air: during the pouring of the base plate 5, it can effectively block cement mortar from entering the bottom opening of the transparent PC container 1, prevent the groove from being blocked by the mortar, and thus ensure that groundwater can smoothly seep into the container.

[0029] Positioning component 4 can firmly anchor this device to the steel reinforcement frame of the base plate 5, preventing it from floating or shifting during pouring and vibration.

[0030] When water enters the transparent PC container 1 through the vent cap 2 via capillary and siphon effects, it successively soaks multiple layers of dyed parts 3 according to the water level. The bottom microcapsule 3-2, middle microcapsule 3-3, and top microcapsule 3-4 contain three drying dyes: green drying dye 3-6, yellow drying dye 3-7, and red drying dye 3-8, respectively. Continuous water immersion causes the microcapsules to dissolve sequentially, releasing the dyes, resulting in different colors appearing from bottom to top within the transparent PC container 1. Observers can visually determine the water level level through the transparent area at the top of the transparent PC container 1, achieving rapid and accurate water level identification.
