[0002] In building construction, due to various reasons, various "joints" need to be left in the structure or other structural levels. These joint parts, as weak links in the waterproof engineering construction, are high-incidence parts of building leakage in the later stage. The traditional waterproof design of construction joints is obsolete. The methods adopted in construction are to set waterstops and expansion rubber strips, etc., but they cannot meet the design requirements. For example, the metal waterstop is offset, the rubber waterstop is bent, etc., and gaps are easily generated at the interface to form a water flow path, directly affecting the waterproof quality and service life of the building. Summary of the Invention

[0015] In summary, due to the adoption of the above technical solutions, the present invention has at least the following beneficial effects: When constructing the waterproof construction joint structure of the basement, by directly chiseling the base surface of the first cast concrete layer into a wavy construction joint structure, the microscopic structure of the base surface of the first concrete layer can be changed, the roughness of the base surface of the first concrete layer can be increased, and capillary-like structures such as small cavities and pores can be extended from the base surface of the first concrete layer into the concrete. After applying the waterproof material on the chiseled concrete base surface to form a waterproof coating layer, the waterproof material can enter the concrete from the base surface of the first concrete layer and react with the chemical substances in the first concrete layer to form small crystals, filling the cavities, pores, etc. in the first concrete layer, further increasing the contact area between the waterproof coating layer and the first concrete layer. The waterproof coating layer can be tightly combined with the first concrete layer to block the seepage channel. After pouring the second concrete layer on the other side of the construction joint, the second concrete layer can further fill the remaining part of the wavy construction joint and chemically react with the active chemical substances in the waterproof coating layer, thereby forming a complete structural system with the waterproof coating layer and the first concrete layer, effectively blocking the seepage channel. Using the active silica self-repairing waterproof coating as the waterproof material not only accelerates the chemical reaction between the special active chemical substances in the active silica self-repairing waterproof coating and the substances in the concrete, but also improves the bonding force between the active silica self-repairing waterproof coating and the concrete joint surface.

[0016] Multiple test blocks made by different processes can produce obvious anti-seepage effects under different pressures. Among them, the test block with wavy chiseling and multi-step multi-layer brushing in the same direction to form the waterproof coating layer has the best anti-seepage effect. It can be seen that when constructing the construction joint of the basement, directly chiseling to form a wavy construction joint structure and using multi-step multi-layer brushing in the same direction at the wavy construction joint to form the waterproof coating layer can effectively prevent groundwater seepage and achieve a good waterproof effect.

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, so that the purpose, technical solution and advantages of the present invention are more clearly understood. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Embodiment 1

[0025] Figure 1 The construction method of the basement waterproof construction joint of an exemplary embodiment of the present invention is shown. The specific construction method includes the following steps: Step 1, pour the first concrete layer on one side of the construction joint; Step 2, roughen the base surface of the first concrete layer into a corrugated shape and perform impurity removal and wetting treatment. Specifically, after the strength of the first concrete layer meets the design requirements: First, directly roughen the base surface of the first concrete layer into a corrugated construction joint structure; Then, remove the floating slurry, oil, grease, demolding agent and other impurities that affect the waterproof effect on the corrugated construction joint structure; Finally, fully wet the base surface of the first concrete layer with clean water (there should be no standing water during construction); Step 3, apply the waterproof material in multiple steps and multiple layers in the same direction to form a waterproof coating layer. The waterproof material is selected as the active silica self-healing waterproof coating. The overall thickness of the waterproof coating layer is 1.5 - 2 mm, and the coating amount is 1.0 - 1.5 kg / square meter. It includes in sequence: Apply the first layer of active silica self-healing waterproof coating, with a coating thickness of 0.8 - 1 mm, and the coating direction should be consistent, uniform and without accumulation; 0.5 hour - 1 hour after the first layer is applied, apply the second layer of active silica self-healing waterproof coating, with a coating thickness of 0.5 - 0.7 mm, and the coating direction should be consistent, uniform and without accumulation; 25 minutes - 50 minutes after the second layer is applied, apply the third layer of active silica self-healing waterproof coating, with a coating thickness of 0.2 - 0.3 mm, and the coating direction should be consistent, uniform and without accumulation; Step 4, check the integrity of the surface of the waterproof coating layer; 15 to 30 minutes after the overall painting is completed, check whether the surface of the waterproof coating layer is flat and smooth, and whether there are defects such as sagging, bubbles, cracking, and peeling. If there are defects, deal with them and supplement the painting of the active silica self-repairing waterproof coating; Step Five, pour the second concrete layer on the other side of the construction joint; Pour the first concrete layer and the second concrete layer according to the design requirements. During pouring, ensure that the vibration is dense to avoid the appearance of hollowing and bubbles. After pouring, carry out maintenance and protection to avoid damage and pollution.

[0026] Using the aforementioned method to construct the basement waterproof construction joint structure, by directly chiseling the base surface of the first poured concrete layer into a corrugated construction joint structure, it can change the microscopic structure of the base surface of the first concrete layer, increase the roughness of the base surface of the first concrete layer, and also form capillary-like structures such as small cavities and pores extending from the base surface of the first concrete layer into the concrete. After applying the waterproof material on the chiseled concrete base surface to form a waterproof coating layer, the waterproof material can enter the concrete from the base surface of the first concrete layer and react with the chemical substances in the first concrete layer to form small crystals, filling the cavities and pores in the first concrete layer, further increasing the contact area between the waterproof coating layer and the first concrete layer. The waterproof coating layer can be tightly combined with the first concrete layer to block the seepage channel; after pouring the second concrete layer on the other side of the construction joint, the second concrete layer can further fill the remaining part of the corrugated construction joint and chemically react with the active chemical substances in the waterproof coating layer, thereby forming a complete structural system with the waterproof coating layer and the first concrete layer, effectively blocking the seepage channel; using the active silica self-repairing waterproof coating as the waterproof material not only accelerates the chemical reaction between the special active chemical substances in the active silica self-repairing waterproof coating and the substances in the concrete, but also improves the adhesion of the active silica self-repairing waterproof coating to the concrete joint surface. Example 2

[0027] This example provides a test method for the basement waterproof construction joint, which specifically includes the following steps: Step A, make test blocks in multiple production boxes using different processes, as Figure 2 shown. The specific steps include: Step A1, pour the first test block in the production box first; Step A2, chisel the base surface of the first test block using different methods. Specifically, after the strength of the first test block meets the requirements, divide the first test block into three groups as a whole, and each group includes one or more first test blocks. Perform ordinary (wavy) chiseling on the first group of first test blocks; First cut the second group of first test blocks into a corrugated shape and then chisel; Perform direct corrugated chiseling on the third group of first test blocks; Step A3: Remove impurities and soak the base surface of Specimen 1. Use an air compressor to blow the head to remove impurities such as floating dust, and soak it with water (but there should be no standing water). Step A4: Apply waterproof materials in multiple steps and multiple layers in the same direction or apply waterproof materials at one time on the base surface of Specimen 1 to form a waterproof coating layer. The applied material is selected as an active silica self-healing waterproof material. Step A5: Pour Specimen 2 on the chiseled side of Specimen 1 after being treated in Step A3 and / or pour Specimen 2 on the surface of the waterproof coating layer of Specimen 1 in Step A4. A construction joint is formed between Specimen 1 and Specimen 2. Step A6: After all specimens meet the strength requirements, cut out an annular groove on the side surface of the specimen along the direction perpendicular to the construction joint. Step A7: Install a sealing ring on the annular groove. In the foregoing steps, Specimen 1 is made of the same material as Concrete Layer 1, and Specimen 2 is made of the same material as Concrete Layer 2 to improve the accuracy of the test results of the basement waterproof construction joint.

[0028] Step B: Place the specimens in the test chamber (the sealing ring on the specimen fits against the inner wall of the test chamber), and conduct a water pressure test on different specimens. The specimens for the water pressure test include: The first specimen with ordinary chiseling without a waterproof coating layer; The second specimen chiseled after being cut into a corrugated shape without a waterproof coating layer; The third specimen with corrugated chiseling without a waterproof coating layer; The fourth specimen with ordinary chiseling with a waterproof coating layer formed by one-time application; The fifth specimen with ordinary chiseling with a waterproof coating layer formed by multiple steps and multiple layers in the same direction; The sixth specimen chiseled after being cut into a corrugated shape with a waterproof coating layer formed by one-time application; The seventh specimen chiseled after being cut into a corrugated shape with a waterproof coating layer formed by multiple steps and multiple layers in the same direction; The eighth specimen with corrugated chiseling with a waterproof coating layer formed by one-time application; The ninth specimen with corrugated chiseling with a waterproof coating layer formed by multiple steps and multiple layers in the same direction; The specific steps of the water pressure test include: Step B1: Keep the pressure unchanged for 8 hours and observe the test effect: There is water seepage in the first specimen; There is infiltration in the second specimen; There is local infiltration in the third specimen; All the other specimens do not have water seepage; Step B2: Pressurize to 1 MPA and maintain for 8 hours, and observe the test effect: There is water seepage in the first test block, the second test block, and the third test block; There is local infiltration in the fourth test block and the sixth test block; All the other test blocks do not have water seepage; Step B3: Pressurize to 2 MPA and maintain for 8 hours, and observe the test effect: There is water seepage in the first test block, the second test block, and the third test block; There is infiltration in the fourth test block; There is local infiltration in the fifth test block, the sixth test block, and the eighth test block; Neither the seventh test block nor the ninth test block has water seepage; Step B4: Pressurize to 5 MPA and maintain for 8 hours, and observe the test effect: There is water seepage in the first test block, the second test block, the third test block, and the fourth test block; There is infiltration in the fifth test block, the sixth test block, and the eighth test block; There is local infiltration in the seventh test block; The ninth test block does not have water seepage.

[0029] Using the foregoing method to conduct a water pressure test on the basement waterproof construction joint, the final test result obtained is that the test block with a corrugated roughening formed by multi-step and multi-layer brushing in the same direction to form a waterproof coating layer has the best water seepage prevention effect. From this, it can be known that when constructing the basement construction joint, directly roughening to form a corrugated construction joint structure and using multi-step and multi-layer brushing in the same direction at the corrugated construction joint to form a waterproof coating layer can effectively prevent groundwater leakage and achieve a good waterproof effect.
