Description

Technical Field

[0001] The invention relates to the technical field of engineering detection, and in particular to a toilet waterproof layer structure and a method for detecting leakage points thereof. Background Art

[0002] The three major waterproofing projects in construction projects are basement waterproofing projects, roof waterproofing projects, and kitchen and bathroom waterproofing projects. Among them, the bathroom is a frequent site for leakage problems and is closely related to people's lives. However, the leakage problem of the bathroom waterproof layer cannot be determined by the common listening method. It is often necessary to solve it by redoing the bathroom waterproof layer, which is time-consuming and costly. So far, no reasonable and effective method has been found to solve the leakage problem of the bathroom waterproof layer. Therefore, how to effectively find the leakage point of the bathroom waterproof layer is particularly important.

[0003] Most of the existing methods and equipment for bathroom penetration points require the destruction of the floor ply structure, resulting in high detection and maintenance costs, low detection accuracy, and easy errors. In addition, most ground structures are installed with steel bars, which makes detection inconvenient, time-consuming and labor-intensive. Summary of the invention

[0004] The purpose of the present invention is to provide a method for detecting a bathroom waterproof layer structure and its leakage points in view of the defects and shortcomings of the prior art. The waterproof layer structure itself does not include a steel structure, and a potential measurement method can be used to detect the penetration point. The detection method is low-cost, fast, effective, highly accurate and safe, and can greatly reduce the maintenance cost of the bathroom.

[0005] To achieve the above object, the present invention adopts the following technical scheme: the bathroom waterproof layer structure comprises a fine stone concrete layer 1, a waterproof layer 2, a cement mortar cushion layer 3, a pure cement slurry bonding layer 4, and floor tiles 5;

[0006] The waterproof layer structure is laid on the surface of the original concrete floor layer 8 below the bathroom 6 and the external house 7. The fine stone concrete layer 1 is laid on the bottom layer of the bathroom 6 and adheres to the original concrete floor layer 8, and the fine stone concrete layer 1 is a pure cement slurry layer; the waterproof layer 2 is adhered to the fine stone concrete layer 1, and the waterproof layer 2 is laid from the leftmost side of the upper surface of the fine stone concrete layer 1 to the leftmost side of the bottom layer of the external house 7, and is fixed by the cement mortar cushion layer 3 laid on the upper surface of the waterproof layer 2; the pure cement slurry bonding layer 4 is laid on the upper surface of the cement mortar cushion layer 3, and the upper surface of the pure cement slurry bonding layer 4 is laid with floor tiles 5, and a threshold stone 9 is arranged between the floor tiles 5 laid in the bathroom 6 and the floor tiles 5 laid in the external house 7;

[0007] The method for detecting the penetration point includes the following steps: First, before the test, the bathroom floor needs to be covered with a layer of water about 2 mm thick, and then Figure 2As shown, the negative electrode of the 100V-250V adjustable boost power supply (voltage UE) is in good and close contact with the water leakage point under the floor, the positive electrode is connected to the positive electrode of the high-sensitivity potentiometer (voltage U meter), and the negative electrode of the high-sensitivity potentiometer is connected to the detection rod. The detection rod is immersed in the bathroom floor covered with water to scan from outside to inside and from left to right to detect the water leakage point. Because the cement mortar cushion layer and the floor are homogeneous, the resistance is evenly distributed. According to the resistance formula Rwater=ρ*Lwater / Swater, the greater the distance Lwater between the detection rod and the water leakage point, the greater the resistance Rwater formed between the detection rod and the water leakage point. According to Kirchhoff's voltage law (KVL) and Ohm's law, it can be obtained that: Umeter=UE-I*Rwater. According to the high-sensitivity potentiometer Umeter, the larger the Umeter, the smaller the Rwater, and the smaller the distance Lwater between the detection rod and the water leakage point, the closer it is to the leakage point in the bathroom.

[0008] The fine stone concrete layer 1 is a C20 fine stone concrete layer. The C20 fine stone concrete layer is sufficient for paving the surface cushion of an ordinary residence.

[0009] The ratio of cement to sand in the cement mortar cushion layer 3 is 1:2. Using the 1:2 cement mortar cushion layer as the adhesive for the waterproof layer 2 and the pure cement slurry bonding layer 4 can make the waterproof performance of the overall structure more stable.

[0010] The threshold stone 9 is a stone threshold. The stone threshold can prevent the moisture in the toilet 6 from penetrating into the external house 7 through the surface gap.

[0011] The working principle of the present invention is that each layer in the waterproof structure is laid in a direct bonding manner, replacing the traditional steel bar and cement fixing method, and the potential measurement method can be used to detect the leakage point. When the leakage point is detected by the method of the present invention, the leakage point resistor R1 under the floor slab, the detection rod resistor R2, the switch K, the boost power supply UE, and the voltmeter V form an electrical circuit. The distance between the detection rod and the leakage point is judged by the resistance formed between the detection rod and the leakage point. The greater the resistance, the greater the distance. Conversely, the smaller the resistance, the smaller the distance.

[0012] After adopting the above technical scheme, the beneficial effects of the present invention are as follows: the waterproof layer structure itself does not include a steel structure, and a potential measurement method can be used to detect penetration points. This detection method is low-cost, fast, effective, highly accurate and safe, and can greatly reduce the maintenance cost of the bathroom. BRIEF DESCRIPTION OF THE DRAWINGS
