Description

Technical Field

[0001] The invention relates to a concrete rigid self-waterproofing performance testing device under high water pressure and a manufacturing method thereof, belonging to the technical field of waterproofing performance testing. Background Art

[0002] In the current construction projects in my country, whether it is public buildings, civil residential buildings or municipal projects, waterproof leakage is common, and waterproof leakage in basements is particularly serious. The waterproof performance of construction projects needs to be paid attention to and effectively optimized and improved. For a long time, my country's construction projects have mainly adopted flexible waterproof systems, mainly relying on multi-layer rolls or coating waterproof layers on the outside of the structure for waterproofing. This flexible waterproof system has low construction tolerance, difficult finished product protection, and short material life, which causes serious leakage. Therefore, it is of great practical significance to adopt a rigid self-repairing waterproof system that is in line with international standards to achieve the same level of anti-leakage effect as developed countries. The rigid self-repairing waterproof system is a cement-based self-repairing permeable crystalline waterproof material that bases the prevention and control of leakage on the structural self-waterproofing construction method to build a long-term waterproof system.

[0003] Generally, concrete test bodies for studying waterproof leakage phenomena are filled with water in an open concrete box for research and observation, and water pressure is basically not considered. The test results of this test body have great limitations, and it is impossible to verify the effectiveness of self-repairing permeable crystalline waterproof materials under high water pressure conditions in deep foundation pit underground projects and their performance such as sealing and sealing. Since most building basements are below the groundwater level, the basement floor and side walls are under the pressure of groundwater to varying degrees. Therefore, in order to more accurately study and verify the waterproofing effect of new self-repairing waterproof materials in weak waterproofing locations such as concrete basement post-casting strips and construction joints under pressure working conditions, and make the test conditions closer to engineering practice, it is urgent to develop a concrete rigid self-waterproofing performance test device under high water pressure. Summary of the invention

[0004] In view of the above existing technical problems, the present invention proposes a test device and manufacturing method for the rigid self-waterproof performance of concrete under high water pressure. The concrete box is equipped with construction joints, post-casting strips, and wall-penetrating pipes, and the concrete is cast according to the construction steps. Before each step of concrete casting, a new self-repairing waterproof material is added to the concrete according to the proportion. This is used to more accurately study and verify the waterproof effect of the new self-repairing waterproof material in the weak waterproof positions such as the post-casting strips and construction joints of the concrete basement under pressure working conditions, so that the test conditions are closer to the actual project.

[0015] S2. Reserved post-casting strip on the bottom plate: There is a post-casting strip on the bottom plate of the test device. Before pouring concrete, the side of the post-casting strip needs to be fixed with a wire mesh to completely restore the construction process of the post-casting strip in the actual project;

[0016] S3. Self-repairing waterproof material is added when mixing concrete: C30 commercial concrete is used, and self-repairing waterproof material is added;

[0031] Furthermore, in step S9, the lower end of the drain pipe should be flush with the bottom surface of the top plate and cannot exceed the concrete surface to prevent the air in the fully enclosed concrete box from being unable to be completely exhausted during the subsequent pressurized water delivery, thereby affecting the test results.

[0032] Furthermore, in step S14, when the water flow debugging of the test device is carried out, it is necessary to keep the drain pipe valve in an open state to inject water into the test device, and then close the drain pipe valve after there are no bubbles in the drain pipe and water is discharged evenly, and then observe the intelligent pressure monitoring and control device, and use a pressure pump to pressurize the test body to a water pressure not exceeding 0.3Mpa and then close the water inlet pipe valve; after the debugging is completed, the leakage of the traditional waterproof weak points such as the bottom plate post-casting strip, side wall post-casting strip, top plate post-casting strip, construction joint, water inlet pipe and drain pipe under a high water pressure environment is observed, and the waterproof effect of the dense crystallization of the concrete with self-repairing waterproof material added in the later stage is observed.

[0033] Furthermore, the intelligent pressure monitoring and control device has the function of intelligently monitoring and automatically adjusting the test pressure inside the test device.

Water inlet pipes and drainage pipes are pre-buried in the side walls and top plate of the box. Switches and intelligent pressure monitoring and control devices are installed on the water pipes. Traditional concrete test bodies for studying waterproof leakage phenomena are filled with water in a concrete box with an open top for research and observation. The present invention realizes a concrete test body for detecting the performance of self-repairing concrete waterproof materials under high water pressure working mode through these processes, which solves the experimental limitations of traditional test bodies working without water pressure. At the same time, the problem of being unable to set leakage test observation data under different pressures is solved.

[0036] 2. A test device and manufacturing method for the rigid self-waterproofing performance of concrete under high water pressure is invented. The intelligent pressure monitoring and control device has the function of intelligent monitoring and automatic adjustment of the test pressure in the test box. When the water pressure inside the box drops to a certain range, the pressure pump can be automatically adjusted to fill the water tank with water and pressurize it, which solves the problem that the test box cannot maintain a constant high pressure state for a long time during the test.

[0044] Example 1

[0045] like Figure 2-6 As shown, a concrete rigid self-waterproofing performance testing device under high water pressure of the present invention comprises a fully enclosed concrete box and a water supply and drainage device.

[0046] The fully enclosed concrete box includes a bottom plate 11, a bottom plate post-casting strip 12, a side wall 13, a side wall post-casting strip 14, and a top plate 15 and a top plate post-casting strip 16.

The water inlet pipe 21 is provided with an intelligent pressure monitoring control device 22 and a water inlet pipe valve 23, and the outer end of the water inlet pipe 21 is connected to a pressure pump 24. The top of the drainage pipe 25 extends out of the top plate 15, and a drainage pipe valve 26 is arranged at the top.

[0048] The fully enclosed concrete box is made of waterproof concrete with self-repairing waterproof materials. The bottom plate, side wall and top plate of the fully enclosed concrete box are 100mm thick and use C30 commercial concrete. The round steel with a diameter of 8mm is arranged in double layers and in two directions with a spacing of 200mm.

[0050] Example 2

[0051] like Figure 1 As shown, the method for manufacturing the concrete rigid self-waterproofing performance test device under high water pressure working of the above-mentioned embodiment 1 includes the following steps:

[0052] S1. Figure 2 As shown, the bottom plate 11 of the fully enclosed concrete box is partially supported by formwork and reinforced with steel bars: according to the construction process, the formwork of the bottom plate 11 is first made, and then the steel bars are tied.

[0053] S2. Reserved post-casting strip on the bottom plate 11: There is a post-casting strip on the bottom plate 11 of the test device. Before pouring concrete, the side of the post-casting strip needs to be fixed with a wire mesh, completely restoring the construction process of the post-casting strip in the actual project.

[0054] S3. Self-repairing waterproof material is added when mixing concrete: C30 commercial concrete is used, and self-repairing waterproof material is added. Self-repairing waterproof material is a cement-based permeable crystalline waterproof material. It is an intelligent self-repairing system formed by compounding active components in traditional concrete components. When cracks or damage occur in concrete materials, the repair reaction is automatically triggered. The active chemical substances contained in the active siliceous repair material use water as a carrier to penetrate and fill the micropores and capillaries of the concrete, allowing the free ions to crystallize again to form dendrite-like crystals, thereby repairing concrete defects, completely cutting off the seepage path, and making the building itself permanently immune to water, achieving the purpose of permanent waterproofing, anti-seepage, reinforcement, and protection of steel bars.

[0055] In this embodiment, the cement-based penetrating crystalline waterproof material is Tongtai active siliceous self-repairing waterproof agent, 3 kilograms of which are added per cubic meter of concrete, accounting for 0.8% of the concrete cementitious material.

[0056] S4. Pouring waterproof concrete for the bottom plate 11: vibrate the concrete during pouring, and perform maintenance after pouring to form the bottom plate 11.

[0057] S5. Figure 3 As shown, the surface of the bottom plate side wall and the construction joint 17 at the bottom plate post-casting strip 12 are cleaned and roughened: one week after the concrete pouring of the bottom plate 11 is completed, the mold is removed, and the bottom plate side wall and the construction joint 17 at the bottom plate post-casting strip 12 are cleaned and roughened.

[0058] S6. Pre-embedded water inlet pipe 21 in side wall 13: When pre-embedded, water inlet pipe 21 is directly pre-embedded without taking traditional waterproof measures such as water stop strip.

[0059] S7. Pour waterproof concrete into the bottom slab post-cast strip 12 and the side wall 13 of the fully enclosed concrete box: The waterproof concrete shall be C30 ordinary commercial concrete mixed with self-repairing waterproof materials, and shall be properly vibrated and maintained.

[0061] S9. Figure 4 As shown, the top plate 15 is pre-buried with a drainage pipe 25: the drainage pipe 25 is directly pre-buried without taking the traditional waterproofing measures of a water stop. The lower end of the drainage pipe 25 should be flush with the bottom surface of the top plate 15 and should not exceed the concrete surface to prevent the air in the fully enclosed concrete box from being exhausted during the later pressurized water delivery, thereby affecting the test results.

[0062] S10. Pour waterproof concrete into the side wall post-casting strip 14 and the top plate 15: The waterproof concrete shall be C30 ordinary commercial concrete, mixed with self-repairing waterproof materials, and vibrated and maintained.

[0065] S13. Figure 6 As shown, the drainage device 2 is installed: the installation process of the intelligent pressure monitoring control device 22, the water inlet pipe valve 23, the pressure water pump 24, and the drainage pipe valve 26 is completed.

[0066] S14. After the construction of the entire test body is completed, the water pressure test begins. In step S14, when the test device is debugged through water, it is necessary to keep the drain pipe valve 26 open to inject water into the test device, and then close the drain pipe valve 26 after there are no bubbles in the drain pipe 25 and the water is discharged evenly, and then observe the intelligent pressure monitoring and control device 22, and use the pressure pump 24 to pressurize the test body to a water pressure not exceeding 0.3Mpa, and then close the water inlet pipe valve 23.
