Description

Technical Field

[0001] The invention relates to the technical field of waterproof construction detection of building underground structures, in particular to waterproof detection equipment for basement waterproof engineering construction. Background Art

[0002] Today's high-rise buildings have deep foundations. Leveraging this depth to construct basements can significantly improve economic and practical benefits, increasing space efficiency. However, basement exterior walls and floors are buried deep underground, subject to infiltration by soil and groundwater. During the cooling process of the wall concrete pour or due to poor construction quality, tiny cracks may develop in the wall structure. Therefore, moisture and waterproofing are crucial issues to address in basement design. Moisture and waterproofing solutions are generally determined based on the basement's standards, structural form, and hydrogeological conditions. Moisture-proofing treatment is appropriate when the basement floor is above the groundwater level. However, moisture and waterproofing treatment is necessary when there's a risk of the basement floor being submerged in groundwater.

[0003] The existing basement waterproofing measures are to use waterproof membranes to lay on the basement floor and walls, or to add an off-wall inner wall on the inner side of the main wall to achieve a multi-layer waterproofing effect. Although the construction technology is becoming more and more perfect, there is currently no testing equipment for basement waterproofing. For the waterproofing of one or high-rise roofs, a closed water test is used to test the waterproofing effect. The existing basement waterproofing effect testing scheme draws on the roof closed water test measures. By observing the degree of water level reduction, it is reflected whether there are small cracks in the wall or the effectiveness of the waterproofing measures. However, although this method is simple to detect, it not only takes a long time to detect, generally requiring 1-3 days of closed water testing, but also uses a large amount of water, wasting water resources. This method will also be affected by factors such as season and geographical location that affect the evaporation of water. Therefore, the method of detecting the effectiveness of waterproofing measures is not accurate, and it is not easy to judge the existence of small cracks and the waterproofing effect. There is an urgent need for a detection device that is convenient for detecting small cracks and the effectiveness of waterproofing measures during the construction phase. Summary of the Invention

At this time, the auxiliary pull rod 5 and the sealing plate 6 remain fixed under the elastic force of the spring 7, so that a negative pressure state is formed in the main tank body.

[0048] Example 1:

[0049] A waterproof detection device for basement waterproofing construction, the detection method is as follows:

[0050] S1: Select the basement wall testing location and pre-treat the concrete at the testing location. This includes smoothing the wall surface, cleaning the concrete joints, and washing away surface dust with water. Then, use drying, airing, and local heating to remove moisture from the wall surface, ensuring that the concrete within half a meter of the testing area remains dry.

[0051] S2: Select the corresponding connector 4 according to the detection position and connect it to the main tank body. After assembly, place the device at the detection position so that the connector 4 is close to the wall;

[0052] S3: The protective gas is delivered to the interior of the main tank through the vent 12, so that the protective gas fills the main tank and the vent pipe 8, and then the vent 12 is sealed with a plug cap 14. The protective gas is a stable gas. The protective gas is non-flammable and non-explosive, does not react with substances such as P2O5 produced during the electrolysis of H3PO4, and does not chemically react with H2O, ensuring that it does not affect the electrolysis reaction inside the device and block the combustion conditions;

[0053] S4: Apply quick-drying adhesive to the outside of the connection between connector 4 and the wall, and wrap sealing tape around the connection between connector 4 and the main tank to keep the inside of the device sealed;

[0054] S5: By pulling the auxiliary pull rod 5, a negative pressure state is formed in the closed cavity formed by the main tank body and the detection wall through the sealing plate 6. The auxiliary pull rod 5 is rotated to insert the support column 52 into the limiting groove 22, so that the sealing plate 6 remains in a fixed position;

[0055] S6: The internal temperature of the main tank is displayed and adjusted through the display screen 31 and the selection button 32 on the control box 3. The temperature and pressure of the negative pressure cavity inside the main tank are monitored through the temperature sensor 16 and the pressure sensor 24. The magnetic fan 82 is started to make the gas inside the main tank flow. The spiral air guide 81 is energized to electrolyze H3PO4 and measure the moisture content in the main tank cavity. The measurement is performed continuously for 2-5 times, and the data is uploaded to the control center 33 and saved.

[0056] S7: Turn off the magnetic fan 82 and the spiral air guide 81 and cut off the power. The internal temperature of the main tank is made 5°-10° higher than the outdoor temperature through the heating plate 15 and the temperature sensor 16. The internal temperature is kept constant and left to stand for 3-8 hours.

[0057] S8: Restart the magnetic fan 82 and the spiral air guide 81, measure the moisture content 2-3 times continuously to obtain the moisture content data, and upload the data to the control center 33 and save it;

[0058] S9: The control center 33 analyzes and compares the two moisture content data and the internal pressure changes to determine the degree of water seepage on the wall. If the change trend of the multiple measurement results is relatively gentle and stable, the waterproof effect is good. If the multiple measurement results change greatly and the moisture content shows a clear upward trend, and the internal pressure decreases slowly, there are tiny cracks on the wall. If the multiple measurement results change greatly and the moisture content shows a clear upward trend, the internal pressure decreases and is consistent with the external atmospheric pressure, it indicates that the main tank body and the wall are not tightly sealed and need to be reinstalled and measured.

[0059] Example 2:

[0060] A waterproof detection device for basement waterproofing construction, the detection method is as follows:

[0061] S1: Select the basement wall testing location and pre-treat the waterproof membrane at the testing location by sweeping or blowing away the dust on the surface with a broom. Then, air-dry the waterproof membrane to remove moisture from the surface and check the dryness to ensure that the waterproof membrane in the testing area remains dry.

[0062] S2: Select the corresponding connector 4 according to the detection position and connect it to the main tank body. After assembly, place the device at the detection position so that the connector 4 is close to the waterproof membrane;

[0063] S3: The protective gas is delivered to the interior of the main tank through the vent 12, so that the protective gas fills the main tank and the vent pipe 8, and then the vent 12 is sealed with a plug cap 14. The protective gas is a stable gas. The protective gas is non-flammable and non-explosive, does not react with substances such as P2O5 produced during the electrolysis of H3PO4, and does not chemically react with H2O, ensuring that it does not affect the electrolysis reaction inside the device and block the combustion conditions;

[0064] S4: Apply quick-drying adhesive to the outside of the connection between connector 4 and the wall, and wrap sealing tape around the connection between connector 4 and the main tank to keep the inside of the device sealed;

[0065] S5: By pulling the auxiliary pull rod 5, a negative pressure state is formed in the closed cavity formed by the main tank body and the waterproof membrane in the detection area through the sealing plate 6. The auxiliary pull rod 5 is rotated so that the support column 52 is inserted into the limiting groove 22, so that the sealing plate 6 remains in a fixed position;

[0066] S6: The internal temperature of the main tank is displayed and adjusted through the display screen 31 and the selection button 32 on the control box 3. The temperature and pressure of the negative pressure cavity inside the main tank are monitored through the temperature sensor 16 and the pressure sensor 24. The magnetic fan 82 is started to make the gas inside the main tank flow. The spiral air guide 81 is energized to electrolyze H3PO4 to measure the moisture content in the main tank cavity. The measurement is repeated 3-7 times.

[0067] S7: Turn off the magnetic fan 82 and the spiral air guide 81 and cut off the power. The internal temperature of the main tank is made 5°-10° higher than the outdoor temperature through the heating plate 15 and the temperature sensor 16. The internal temperature is kept constant and left to stand for 3-8 hours.

If the multiple measurement results change greatly and the moisture content shows a clear upward trend, and the internal pressure decreases slowly, there are tiny cracks on the wall. If the multiple measurement results change greatly and the moisture content shows a clear upward trend, the internal pressure decreases and is consistent with the external atmospheric pressure, it indicates that the main tank body and the waterproof membrane are not tightly sealed and need to be reinstalled and measured.
