Description
Technical Field
[0001] This application relates to the field of water plant tank construction, and in particular to a self-healing waterproof water plant tank. Background Art
[0002] As the core structure to ensure water quality safety, the water plant tank has the characteristics of large plane size, large amount of concrete pouring, and high pouring intensity. The water plant tank is prone to large temperature difference between the inside and outside of the concrete due to temperature rise, resulting in concrete cracking, which seriously affects the service life of the water plant tank structure. Improving the crack resistance and waterproof performance of the tank has become a key problem to be solved urgently.
[0003] In the construction of water plant tanks, traditional waterproof methods mainly focus on the application of external waterproof layers, but often ignore the heterogeneity and porous characteristics of the concrete material itself. These characteristics make the concrete prone to form crack channels under the influence of multiple factors such as long-term load bearing, temperature change and structural stress, thus threatening the structural safety. In addition, there are also many problems with external waterproof layers. They may be damaged due to material aging, construction defects or external environmental erosion, ultimately leading to leakage problems. Summary of the Invention
[0004] In order to reduce the probability of leakage of the water plant tank, this application provides a self-healing waterproof water plant tank.
[0005] A self-healing waterproof water plant tank provided by this application adopts the following technical solutions: A self-healing waterproof water plant tank includes a concrete main body, a waterproof layer and a lining layer. The lining layer is fixedly connected to the outer wall of the concrete main body, the lining layer covers the surface of the concrete main body, the waterproof layer is fixedly connected to the outer wall of the lining layer, the waterproof layer covers the surface of the lining layer. The lining layer is set as a penetrating crystalline coating, and the waterproof layer is set as polymer cement waterproof mortar.
[0006] By adopting the above technical solutions, the penetrating crystalline coating generates crystals when encountering water, blocking pores. The waterproof layer and the lining layer provide double and all-round protection for the concrete main body, reducing the probability of leakage of the water plant tank.
[0007] Preferably, it further includes a rubber waterstop tape. The concrete main body includes a pool bottom and a pool wall. The pool wall is fixedly connected to the upper end of the pool bottom. There are multiple pool walls, and the multiple pool walls are arranged in sequence along the edge of the pool bottom. Adjacent pool walls are fixedly connected to each other. The joint between adjacent pool walls is set as the first anti-seepage joint, and the joint between the pool bottom and the pool wall is set as the second anti-seepage joint. The rubber waterstop tape covers the first anti-seepage joint and the second anti-seepage joint.
[0008] By adopting the above technical solutions, after pouring the bottom of the pool, the pool wall is cast in sections, which improves the construction efficiency and quality. The rubber water stop tape covers all joints, reducing the probability of leakage of the water plant pool body.
[0009] Preferably, it further includes a water-swelling water stop strip. One side of the water-swelling water stop strip is fixedly connected to the bottom and the wall of the pool.

The water-swelling water stop strip covers the first anti-seepage joint and the second anti-seepage joint, and the rubber water stop tape covers the first anti-seepage joint and the second anti-seepage joint.
[0010] By adopting the above technical solutions, when the rubber water stop strip is damaged due to the deformation of the concrete main body, as the concrete main body deforms, the joint is prone to water leakage.

At the same time, the expanded part is convenient for the operator to repair the pool.

One side of the elastic sealant is fixedly connected to the bottom and the wall of the pool. The other side of the elastic sealant is fixedly connected to the rubber water stop tape.
[0012] By adopting the above technical solutions, the elastic sealant seals the water-swelling water stop strip between the rubber water stop tape and the concrete main body, reducing the probability of the water-swelling water stop strip contacting water when the concrete main body deforms, and facilitating the realization of the anti-seepage effect when the concrete main body cracks.
[0013] Preferably, the concrete main body further includes polymer microcapsules. The polymer microcapsules include a capsule body and a repair agent. The repair agent is arranged inside the capsule body. There are multiple polymer microcapsules, and the multiple polymer microcapsules are respectively arranged in the first anti-seepage joint and the second anti-seepage joint.
[0014] By adopting the above technical solutions, when the crack expands, the capsule body ruptures to release the repair agent, achieving instant healing and reducing the probability of leakage of the water plant pool body. The material of the capsule body is set as epoxy resin or polyurethane microcapsule.
[0015] Preferably, it further includes a steel reinforcement cage and cooling pipes. The steel reinforcement cage is arranged inside the concrete main body. The cooling pipes are fixedly connected to the steel reinforcement cage. Both ends of the cooling pipes extend out of the concrete main body, and a water inlet and a water outlet are respectively arranged at both ends of the cooling pipes.
[0016] By adopting the above technical solutions, circulating water is introduced into the cooling pipes to reduce the temperature difference between the inside and outside of the concrete main body, thereby reducing the probability of cracking of the concrete main body.
[0017] Preferably, it further includes a water pump. The bottom and the wall of the pool enclose a water storage tank. The water pump is arranged in the water storage tank. The water inlet is communicated with the outlet of the water pump, and the water outlet is communicated with the inlet of the water pump.
[0018] By adopting the above technical solution, the water in the waterworks pool body is introduced into the cooling pipe, reducing the temperature difference between the inside and outside of the concrete main body and reducing the probability of the concrete main body cracking.
[0019] Preferably, the concrete main body includes cement, fly ash, slag, expansion compensator and steel fiber, and the fly ash, slag, expansion compensator and steel fiber are incorporated into the cement.
[0020] By adopting the above technical solution, the fly ash and slag improve the compactness of the concrete main body, reducing the probability of water seepage from the voids in the concrete. The steel fiber improves the structural strength of the concrete main body, and the expansion compensator compensates for the shrinkage stress of the concrete main body, reducing the probability of the concrete main body cracking.
[0021] Preferably, the concrete main body further includes a nutrient source. The nutrient source includes Bacillus and calcium lactate, and the nutrient source is incorporated into the cement.
[0022] By adopting the above technical solution, when cracks occur in the concrete main body or the cooling pipe ruptures, water seeps into the concrete main body, and the nutrient source metabolizes to generate calcium carbonate crystals to seal the cracks.
[0023] Preferably, it further includes an elastic sealing ring and a waterproof sealant. The elastic sealing ring is sleeved on the outer periphery of the cooling pipe. The elastic sealing ring is fixedly connected to the outer wall of the waterproof layer. The waterproof sealant is arranged between the elastic sealing ring and the cooling pipe, and the waterproof sealant is fixedly connected to the elastic sealing ring and the cooling pipe.
[0024] By adopting the above technical solution, the probability of water leakage from the joint between the cooling pipe and the concrete main body is reduced, and the service life of the waterworks pool body is extended.
[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1.

At the same time, the swelling part is convenient for operators to repair the water tank; 3. When cracks occur in the concrete main body or the cooling pipe ruptures, water seeps into the concrete main body, and the nutrient source metabolizes to generate calcium carbonate crystals to seal the cracks.
