[0049] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0050] like Figures 1 to 3 As shown, the present application provides a bottom plate leakage detection method, wherein a concrete surface layer 2 is laid on a bottom plate 1, and the bottom plate leakage detection method comprises:

[0051] An observation port 21 is opened on the concrete surface layer 2, and the observation port 21 vertically penetrates the concrete surface layer 2, so that the bottom plate 1 is exposed at the position of the observation port 21, so as to observe the direction of water leakage at the observation port 21, thereby preliminarily judging the direction of the leakage position 11 of the bottom plate 1.

[0052] Furthermore, in the observation port 21, a detection medium 3 is laid on the bottom plate 1. When the detection medium 3 encounters water, it will be displaced to generate accumulation pores. The position 31 where the accumulation pores are generated in the detection medium 3 is observed, and the direction of the leakage position 11 of the bottom plate 1 relative to the observation port 21 is determined. For example, Figure 3 As shown in Figure 3 At the leftmost side of the observation port 21 , the detection medium 3 generates accumulation pores, the height of the left side of the detection medium 3 decreases, and it accumulates to the right side and pores appear. At this time, it can be determined that the leakage position 11 of the bottom plate 1 is located on the left side of the observation port 21 .

[0053] The above two steps are repeated in the direction of the leakage position 11 of the bottom plate 1 relative to the observation port 21 until it is determined that the leakage position 11 of the bottom plate 1 is located between at least two observation ports 21 at a preset distance. By continuously repeating the above steps, a new observation port 21 is opened in the direction of the leakage position 11 of the bottom plate 1 relative to each observation port 21 until it is determined that the leakage position 11 of the bottom plate 1 is located between at least two observation ports 21 at a preset distance, which is equivalent to defining the area where the leakage position 11 of the bottom plate 1 is located by at least two observation ports 21. At this time, the concrete surface layer 2 is removed in the area between the two observation ports 21 to find the leakage position 11 of the bottom plate 1. There is no need to completely remove the concrete surface layer 2, which can effectively reduce the impact on the normal use of the building when finding and repairing the leakage position 11, and reduce the cost of finding and repairing the leakage position.

[0054] Optionally, before laying the detection medium 3 inside the observation port 21, the base plate 1 is cleaned to remove water and impurities on the base plate 1 to ensure the cleanliness of the base plate 1. After laying the detection medium 3, it can prevent water from interfering with the sedimentation position of the detection medium 3 and impurities from hindering the sedimentation of the sedimentation medium, thereby ensuring the accuracy of the sedimentation position of the detection medium 3 and thus ensuring the accuracy of the detection result.

[0055] like Figure 4 and Figure 5 As shown, the present application provides a bottom plate leakage detection method, wherein the bottom plate leakage detection method comprises:

[0056] At least one first observation port 211 is opened on the concrete surface layer 2, and the first observation port 211 vertically penetrates the concrete surface layer 2; the bottom plate 1 is exposed at the position of the first observation port 211, so that the direction of water gushing out can be observed at the first observation port 211, thereby preliminarily determining the direction of the leakage position 11 of the bottom plate 1.

[0057] Furthermore, in the first observation port 211, the detection medium 3 is laid on the bottom plate 1, the position 31 where the accumulation pores of the detection medium 3 are generated is observed, and the direction of the leakage position 11 of the bottom plate 1 relative to the first observation port 211 is determined; illustratively, as Figure 5 As shown, in Figure 5 The observation port 21 located on the far left and the observation port 21 located on the far right are both first observation ports 211. When the detection medium 3 in the observation port 21 located on the far left generates accumulation pores, the height of the right side of the detection medium 3 decreases and accumulates to the left. When the detection medium 3 in the observation port 21 located on the far right generates accumulation pores, the height of the left side of the detection medium 3 decreases and accumulates to the right. At this time, it can be determined that the leakage position of the bottom plate 1 is located between the two first observation ports 211.

[0058] In the direction of the leakage position 11 of the bottom plate 1 relative to the first observation port 211, a plurality of second observation ports 212 are sequentially opened on the concrete surface layer 2, and the second observation ports 212 vertically penetrate the concrete surface layer 2; similarly, the detection medium 3 is laid on the bottom plate 1 in the second observation port 212, and the position 31 where the accumulation pores of the detection medium 3 are generated is observed, and the direction of the leakage position 11 of the bottom plate 1 relative to each second observation port 212 is determined, until it is determined that the leakage position 11 of the bottom plate 1 is located between at least two second observation ports 212 at a preset distance from each other; by determining the leakage position 11 of the bottom plate 1 relative to each first observation port 21 1, until it is determined that the leakage position 11 of the bottom plate 1 is located between at least two second observation ports 212 that are at a preset distance, it is equivalent to further narrowing the area where the leakage position 11 of the bottom plate 1 is located within the range defined by the first observation port 211 through at least two second observation ports 212. At this time, the concrete surface layer 2 is removed in the area between the two second observation ports 212, and the leakage position 11 of the bottom plate 1 can be found, without the need to completely remove the concrete surface layer 2, which can effectively reduce the impact on the normal use of the building when finding and repairing the leakage position 11, and reduce the cost of finding and repairing the leakage position.

[0059] Alternatively, if Figure 4 As shown, the opening area of ​​the first observation port 211 is larger than the opening area of ​​the second observation port 212. In this way, the leakage position 11 of the bottom plate 1 can be preliminarily determined through the first observation port 211, and the leakage position 11 of the bottom plate 1 can be further accurately determined through the second observation port 212, and the damage caused by the second observation port 212 to the concrete surface layer 2 can be reduced, thereby reducing the amount of restoration work for the concrete surface layer 2 after the bottom plate 1 is repaired.

[0060] like Figure 4 As shown, in the bottom plate leakage detection method provided by the present application, the first observation port 211 is a strip-shaped observation port 21 , and illustratively, can be a long rectangular observation port 21 .

[0061] Two first observation ports 211 are provided; one of the first observation ports 211 extends along a first direction X, and the other of the first observation ports 211 extends along a second direction Y, and the first direction X is perpendicular to the second direction Y.

[0062] The first observation port 211 and the second observation port 212 are roughly matched to form an angle of 90°, and each second observation port 212 is arranged in the angle formed by the two first observation ports 211. It can be understood that one of the first observation ports 211 divides the area of ​​the bottom plate 1 into two halves, and determines that the leakage position 11 of the bottom plate 1 is in one half, and the other first observation port 211 further divides the half of the bottom plate 1 into two halves, and the area of ​​the region where the leakage position 11 of the bottom plate 1 is located is further reduced by detecting the sedimentation position of the medium 3 in the two first observation ports 211. At this time, the second observation port 212 is set in this area, and the second observation ports 212 are arranged at intervals along the first direction X and / or the second direction Y; in this way, the area where the leakage position 11 of the bottom plate 1 is located is further reduced.

[0063] like Figure 5 As shown, the bottom plate leakage detection method provided by the present application, wherein the first observation port 211 is a strip-shaped observation port 21, and two first observation ports 211 are provided;

[0064] Both the two first observation ports 211 extend along the first direction X, and the two first observation ports 211 are arranged at intervals along the second direction Y, and each second observation port 212 is located between the two first observation ports 211. It can be understood that the area of ​​the bottom plate 1 is divided into three parts by two mutually parallel first observation ports 211, and the area of ​​the area where the leakage position 11 of the bottom plate 1 is located is further reduced by the sedimentation position of the detection medium 3 in the two first observation ports 211. At this time, the second observation ports 212 are arranged in the area, and the second observation ports 212 are arranged at intervals along the first direction X and / or the second direction Y; in this way, the area where the leakage position 11 of the bottom plate 1 is located is further reduced.

[0065] For example, the base plate 1 is a basement base plate 1, and the basement floor is divided into a driving lane and a parking space. The first observation port 211 is opened at the edge of the driving lane and / or the parking space line of the parking space. The first observation port 211 cannot cross the driving lane or the parking space to ensure that the road surface of the driving lane and the parking space is flat. After the approximate leakage position 11 of the base plate 1 is determined through the first observation port 211, a second observation port 212 can be opened on the road surface of the driving lane and / or the parking space to further reduce the area where the leakage position 11 of the base plate 1 is located. Since the size of the second observation port 212 is smaller than that of the first observation port 211, the impact on the road surface of the driving lane or the parking space is relatively small.

[0066] like Figure 4As shown, the base plate leakage detection method provided by the present application, wherein the second observation port 212 is a circular observation port 21. Compared with the polygonal observation port 21, the circular observation port 21 is beneficial to optimizing the stress of the concrete surface layer 2 and reducing the cracking of the concrete surface layer 2 caused by uneven stress around the observation port 21.

[0067] The diameter of the circular observation port 21 is greater than or equal to 5 cm, so as to ensure that the second observation port 212 has a sufficient opening area for the staff to clearly judge the sedimentation position of the detection medium 3.

[0068] The preset distance between the second observation ports 212 is greater than or equal to 1 m and less than or equal to 2 m, so as to enhance the reference value of each second observation port 212 and more accurately find the area where the leakage position 11 of the bottom plate 1 is located.

[0069] like Figures 6 to 8 As shown, the present application provides a method for detecting leakage of a bottom plate, wherein an indicator device 4 is provided in the second observation port 212, and the indicator device 4 can display the position of the water level in the second observation port 212, and the direction of the water level relative to the second observation port 212 is the direction of the leakage position 11 of the bottom plate 1 relative to the second observation port 212. Since the size of the second observation port 212 is small, when the leakage of the bottom plate 1 is more complicated, it may cause the medium sedimentation therein to be difficult to observe. At this time, the indicator device 4 can further simplify the difficulty of the staff to observe the detection medium 3 at the second observation port 212, thereby improving the accuracy of the judgment.

[0070] like Figures 6 to 8 As shown, the bottom plate leakage detection method provided by the present application, wherein the indicating device 4 includes an indicating disk 41, a plurality of indicating sliders 42 and a plurality of transmission components 43.

[0071] A plurality of tracks 411 are provided on the indicator disk 41, each track 411 extends from the center of the indicator disk 41 to the edge of the indicator disk 41, and each track 411 is evenly spaced along the circumference of the indicator disk 41; the indicator disk 41 is a circular disk, and each track 411 extends in a radial shape from the center of the indicator disk 41 to the edge of the indicator disk 41.

[0072] An indicating slider 42 is slidably disposed in each track 411 , and each indicating slider 42 has an initial position in the corresponding track 411 . Specifically, the initial position is an end of the track 411 close to the center of the indicating plate 41 .

[0073] One end of each transmission member 43 is rotatably connected to an indicating slider 42, and the other end of the transmission member 43 is inserted into the detection medium 3. When the detection medium 3 remains stationary, each transmission member 43 and the corresponding indicating slider 42 remain stationary, and each indicating slider 42 is located at the initial position. In the process of generating accumulation pores in the detection medium 3, the transmission member 43 can be driven to drive the indicating slider 42 to move along the track 411 in a direction away from the center of the indicating disk 41 to deviate from the initial position. By observing the position of each indicating slider 42 in the track 411, the staff can determine the sedimentation position of the detection medium 3, thereby determining the direction of the leakage position 11 of the bottom plate 1.

[0074] Optionally, a colored coating or mark is provided on the indicating slider 42 to facilitate the staff to accurately find the indicating slider 42 and observe it.

[0075] Optionally, a guide rail is formed on the lower surface of the indicator plate 41 to be connected to the transmission member 43 . The indicator plate 41 is made of a transparent material so that the movement of the indicator slider 42 can be observed through the indicator plate 41 .

[0076] like Figure 7 As shown, the bottom plate leakage detection method provided by the present application, wherein the transmission component 43 includes a first connecting rod 431 and a second connecting rod 432, the first end of the first connecting rod 431 is rotatably connected to the indicating slider 42, the second end of the first connecting rod 431 is rotatably connected to the first end of the second connecting rod 432, and the second end of the second connecting rod 432 is inserted into the detection medium 3.

[0077] The indicating device 4 also includes a support rod 44 and a support plate 45. The support plate 45 is spaced apart on the side of the indicating plate 41 facing the detection medium 3, and the support plate 45 is concentrically arranged with the indicating plate 41. The support rod 44 is vertically connected between the indicating plate 41 and the support plate 45. Each second connecting rod 432 is rotatably connected to the edge of the support plate 45. The connection position between the second connecting rod 432 and the support plate 45 is located between the first end and the second end of the second connecting rod 432.

[0078] By setting the support plate 45 connected to the indicator plate 41 through the support rod 44, a mounting base is provided for the second connecting rod 432 and its movement is limited, so that when the second connecting rod 432 is subjected to external force, it can only swing around the rotation connection between it and the support plate 45.

[0079] During the sedimentation of the detection medium 3, the detection medium 3 moves and pushes the second end of the second connecting rod 432 to move. At this time, the first end of the second connecting rod 432 swings and drives the second end of the first connecting rod 431 to move, thereby pushing the first connecting rod 431 to move as a whole and driving the indicating slider 42 to move along the track 411 to deviate from the initial position.

[0080] like Figure 7 As shown, the bottom plate leakage detection method provided by the present application, wherein the transmission member 43 also includes a force-bearing sheet 433, the force-bearing sheet 433 is connected to the second end of the second connecting rod 432, and when the indicating slider 42 is in the initial position, the force-bearing sheet 433 is perpendicular to the bottom plate 1, and the force-bearing sheet 433 has a force-bearing surface facing the center of the second observation port 212. With such a configuration, during the sedimentation of the detection medium 3, the contact area between the force-bearing sheet 433 and the detection medium 3 can be increased, thereby ensuring that the second end of the second connecting rod 432 is subjected to a thrust during the sedimentation of the detection medium 3, and ensuring that it can move with the movement of the detection medium 3 during the sedimentation of the detection medium 3, driving the indicating slider 42 to deviate from the initial position.

[0081] Optionally, in the base plate leakage detection method provided by the present application, the detection medium 3 is sand particles, the fineness modulus of the sand particles is less than 1.3, and they have good fluidity when meeting water to ensure their sedimentation effect.

[0082] Optionally, in the bottom plate leakage detection method provided by the present application, the laying thickness of the detection medium 3 in the observation port 21 is greater than or equal to 1 cm, so as to ensure that the detection medium 3 can be clearly observed after settling.

[0083] Optionally, the present application provides a method for detecting leakage of a bottom plate, wherein the method for detecting leakage of a bottom plate further comprises defining an apparent leakage range on the surface of the concrete surface layer 2, wherein the first observation port 211 and the second observation port 212 are both opened inside the apparent leakage range. The apparent leakage range is determined based on the area of ​​the surface of the concrete surface layer 2 that is soaked by water. Since when leakage occurs on the bottom plate 1, water is likely to diffuse from the leakage position 11 to the surroundings, and the leakage position 11 is likely to be located within the apparent leakage range, defining the apparent leakage range can effectively reduce the area of ​​the region where the leakage position 11 of the bottom plate 1 is located.

[0084] The base plate leakage detection method provided in the present application, by opening an observation port 21 on the concrete surface layer 2 and laying a detection medium 3 in the observation port 21, can determine the direction of the leakage position 11 of the base plate 1 relative to the observation port 21 according to the position 31 of the accumulation pores generated by the detection medium 3 in the observation port 21, and by continuously repeating the above steps, a new observation port 21 is opened in the direction of the leakage position 11 of the base plate 1 relative to each observation port 21, until it is determined that the leakage position 11 of the base plate 1 is located between at least two of the observation ports 21 with a preset distance, which is equivalent to defining the area where the leakage position 11 of the base plate 1 is located by at least two observation ports 21. At this time, the concrete surface layer 2 is removed in the area between the two observation ports 21, and the leakage position 11 of the base plate 1 can be found without completely removing the concrete surface layer 2, which can effectively reduce the impact on the normal use of the building when finding and repairing the leakage position 11, and reduce the cost of finding and repairing the leakage position.

In the description of this application, unless otherwise specified, "plurality" means two or more.
