[0002] Waterproof membranes are waterproof materials made by impregnating asphalt or polymer waterproof materials onto a substrate and are provided in the form of rolls. Commonly used waterproof membranes can be generally divided into three categories based on the composition of the raw materials: asphalt waterproof membranes, polymer-modified asphalt waterproof membranes, and synthetic polymer waterproof membranes.

[0003] Waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc. to prevent external rainwater and groundwater leakage. As a leak-free connection between the project foundation and the building, they are the first barrier to waterproofing the entire project and play a vital role in the entire project.

[0004] When waterproof membranes are used, their waterproof effect will gradually decrease due to the deformation of walls or roads.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Example 1:

[0038] Reference Figure 1-10 , a sample detection device for preparing waterproof membrane, comprising:

[0039] Detection rack 1;

[0040] Among them, the detection frame 1 is provided with a water storage chamber 101. When the waterproof membrane sample is fixed on the detection frame 1, the water storage chamber 101 starts to store water;

[0041] Four tensioning seats 3 sliding on the detection frame 1 in a cross shape;

[0042] Among them, the tensioning seat 3 is used to clamp the four corners of the waterproof membrane sample, and is located at the four corners of the detection frame 1 after the tensioning seat 3 slides;

[0043] The cover plate 2 is detachably connected to the detection frame 1. Specifically, threaded columns 102 are provided at the upper part of the four corners of the detection frame 1. A nut 201 is provided at the upper end of the cover plate 2. The nut 201 is threadedly connected to the threaded column 102. When the cover plate 2 is inserted into the threaded column 102, the nut 201 is screwed to lock the cover plate 2. Secondly, a sealing strip 202 is fixedly connected to the lower end of the cover plate 2 for sealing the connection between the cover plate 2 and the detection frame 1 when the cover plate 2 is covered on the detection frame 1.

[0044] The cover plate 2 is located at the upper end of the water storage chamber 101 and is provided with a water inlet 203 and an air filling port 204;

[0045] After the waterproof coiled material sample is pulled and stretched, water is injected into the water storage chamber 101 , and then the waterproof test of the stretched waterproof coiled material sample can be performed.

[0046] The tensioning seat 3 is provided with an angle pressure groove 301, in which an angle pressure plate 302 is slidably connected. The tensioning seat 3 is rotatably connected with an adjusting bolt 303, which is threadedly connected to the angle pressure plate 302.

[0047] When the four corners of the waterproof membrane sample need to be fixed, first place the four corners of the waterproof membrane sample into the corner pressure groove 301. At this time, the adjusting bolt 303 can be turned by a hexagonal wrench. Under the action of the thread, the adjusting bolt 303 can adjust the position of the corner pressure plate 302 in the corner pressure groove 301, so that the corner pressure plate 302 presses the waterproof membrane sample to complete the fixation.

[0048] The detection frame 1 is provided with a side pressure groove 103, which is arranged on the same plane as the corner pressure groove 301. A side pressure plate 104 is slidably connected in the side pressure groove 103, and a pressure column 106 is fixedly connected to the side pressure plate 104. The pressure column 106 matches the cover plate 2, and a return spring 105 is sleeved on the pressure column 106. The return spring 105 is used to drive the pressure column 106 to reset when the pressure column 106 is not squeezed. The two ends of the return spring 105 are respectively fixedly connected to the detection frame 1 and the side pressure plate 104;

[0049] The upper end of the pressure column 106 is fixedly connected to a compression spring 107, and the compression spring 107 is located between the pressure column 106 and the cover plate 2;

[0050] When the side of the waterproof membrane sample needs to be fixed, when the four corners of the waterproof membrane sample are opened, the side of the waterproof membrane sample is tightened and enters the side pressure groove 103. At this time, the cover plate 2 is covered. The cover plate 2 will squeeze the pressure column 106 and the side pressure plate 104 downward through the compression spring 107 to fix the side of the waterproof membrane sample.

[0051] The detection frame 1 is fixedly connected to a guide support rod 4 arranged in a cross shape. Specifically, the length of the cross guide support rod 4 is a preset length. The tensioning seat 3 is slidably connected to the guide support rod 4. The center of the cross of the guide support rod 4 is fixedly connected to a middle support plate 307. The middle support plate 307 is fixedly connected to a winch motor 308. The output end of the winch motor 308 is fixedly connected to a capstan 309. The capstan 309 is fixedly connected to a pull rope 304. The other end of the pull rope 304 is connected to the tensioning seat 3 for pulling the tensioning seat 3 to slide.

[0052] When the waterproof membrane sample needs to be pulled open, the winch motor 308 is started, and the winch motor 308 drives the capstan 309 to rotate, so that the pull rope 304 is wound around the capstan 309, and then the other end of the pull rope 304 can pull the tensioning seat 3, so that the tensioning seat 3 slides along the cross-shaped guide support rod 4, so that the four corners of the waterproof membrane sample slide in four directions and are stretched.

[0053] The detection frame 1 is fixedly connected to a reversing wheel 305, a pull rope 304 is attached to the reversing wheel 305, a pulling spring 306 is sleeved on the guide support rod 4, and both ends of the pulling spring 306 are fixedly connected to the middle support plate 307 and the tensioning seat 3 respectively;

[0054] Specifically, the reversing wheel 305 is provided to reverse the pulling direction of the pull rope 304, thereby reducing the overall usage space of the device.

[0055] The cover plate 2 is symmetrically fixedly connected to the partition plate 2. The water storage chamber 101 includes a middle cavity 206 arranged between the two partition plates 205 and side cavities 207 arranged on both sides of the partition plates 205. The middle cavity 206 is connected to the water inlet 203, and the side cavities 207 are connected to the inflation port 204. A through groove is provided on the partition plate 205. The support plate 108 is fixedly connected to the detection frame 1, and the partition plate 205 is located directly above the support plate 108.

[0056] After water is injected, the water level overflows the through groove. At this time, air is inflated into the side cavity 207 through the air inlet 204, which can increase the air pressure in the side cavity 207. This increases the pressure of the water on the waterproof membrane sample, and can realize water seepage detection under different pressure conditions.

[0057] Secondly, the water pressure in the middle cavity 206 is lower than the water pressure in the side cavity 207, so that the waterproof membrane samples in the side cavity 207 are subjected to greater pressure. That is, when the waterproof membrane samples in the two side cavities 207 are pressed downward, they will further pull the waterproof membrane samples in the middle cavity 206 to simulate the waterproof condition of the waterproof membrane when the wall cracks.

[0058] The detection frame 1 is fixedly connected to a detection support plate 503, and the detection support plate 503 is slidably connected to a detection plate 5. The detection plate 5 is located below the waterproof membrane sample. The detection plate 5 is provided with a detection slot 501, and the detection slot 501 is connected to a detection collection rack;

[0059] When the waterproofing membrane leaks water, the water will drip onto the detection and collection rack. At this time, by observing the distribution position of the water on the detection plate 5, the location of the water leakage in the waterproofing membrane can be known.

[0060] The detection collection rack includes multiple groups of detection collection sub-racks 502, and the detection slots 501 pass through the detection plate 5. After one group is detected, the detection collection sub-rack 502 can be pushed out from the bottom of the detection collection sub-rack 502 through the detection slots 501, which facilitates the replacement of the detection collection rack.

[0061] Example 2:

[0062] Reference Figure 1-10 , a sample detection device for preparing waterproof membrane, mainly comprising the following steps:

[0063] Step 1: Fix the four corners of the waterproof membrane sample on the tensioning seat 3, and pull the four corners of the waterproof membrane sample in four directions: Place the four corners of the waterproof membrane sample into the corner pressure groove 301. At this time, the adjusting bolt 303 can be turned by the hexagonal wrench. Under the action of the thread, the adjusting bolt 303 can adjust the position of the corner pressure plate 302 in the corner pressure groove 301, so that the corner pressure plate 302 presses the waterproof membrane sample tightly to complete the fixation;

[0064] The winch motor 308 is started, and the winch motor 308 drives the winch 309 to rotate, so that the pull rope 304 is wound around the winch 309, and then the other end of the pull rope 304 can pull the tensioning seat 3, so that the tensioning seat 3 slides along the cross-shaped guide support rod 4, so that the four corners of the waterproof membrane sample slide in four directions and are stretched;

[0065] Step 2: Fix the side of the waterproof membrane sample on the inner wall of the test frame 1. When the four corners of the waterproof membrane sample are opened, the side of the waterproof membrane sample is tightened and enters the side pressure groove 103. At this time, the cover plate 2 is covered. The cover plate 2 will squeeze the pressure column 106 and the side pressure plate 104 downward through the compression spring 107 to fix the side of the waterproof membrane sample, so that a water storage chamber 101 is formed between the waterproof membrane sample and the test frame 1.

[0066] Step 3: Install the cover plate 2 on the upper end of the test frame 1 to cover the water storage chamber 101. At this time, stop filling the water storage chamber 101 with water through the water inlet 203 and observe whether there is water dripping from the lower end of the waterproof membrane. At this time, the waterproof membrane sample can be tested for waterproofness while being stretched.

[0067] Step 4: Repeat water filling to perform waterproof testing at different water depths and water pressures;

[0068] Step 5: When the water level overflows the through groove, stop filling the water and seal the water inlet 203. At this time, fill the side cavity 207 with air through the air inlet 204 to increase the water pressure, so that waterproof testing can be performed under different water pressures.

[0069] Secondly, the gas in the side cavity 207 will not enter the middle cavity 206, so that the water pressure in the side cavity 207 pressurizes the waterproof membrane sample in the side cavity 207, which produces a pulling effect on the waterproof membrane sample in the middle cavity 206, and performs waterproof testing on the waterproof membrane sample.

[0070] Example 3:

[0071] Reference Figure 1-10 A sample detection device for preparing waterproof membranes is basically the same as Example 2, except that the detection frame 1 is tilted at an angle of 1-10°. When detecting the waterproof condition of the waterproof membrane sample, if the waterproof membrane sample has little water seepage, the seeped water can drip along the tilted waterproof membrane sample to one side of the detection collection frame, so that whether there is water seepage can be observed in a relatively short time.

[0072] The tensioning seat 3 provided in the present invention facilitates pulling the waterproof membrane sample and performing a tensile test on the waterproof membrane sample. At the same time, the water storage chamber 101 provided facilitates water seepage test on the waterproof membrane sample. At the same time, the pressurization method is adopted to test different water pressure conditions, reduce water usage, and expand the test range.

[0073] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
