Waterstop innovation: new products and technological innovation of the waterproofing revolution
In the field of building waterproofing, waterstop as a key component to prevent water leakage, play a decisive role in ensuring the waterproof performance and durability of the project. With the continuous development of construction technology and the increasingly stringent requirements for waterproofing, waterstop products are also continuing to innovate, a series of new products and technological innovations continue to emerge for various types of construction projects to provide a more reliable waterproofing protection.
New waterstop product characteristics
1. Composite waterstop: This is an innovative product that combines the advantages of a variety of materials. It is usually made of rubber and polymer composite materials, rubber part has excellent elasticity and flexibility, can effectively adapt to the expansion and contraction of the concrete deformation; polymer materials enhance the strength and aging resistance of the waterstop. For example, in some large-scale water conservancy projects, concrete will be due to temperature changes and water pressure to produce large deformation, composite water stopper with its unique combination of materials, in the expansion joints at the close fit, effectively preventing water leakage, significantly extending the service life of the project.
2. Self-healing waterstop: self-healing waterstop is a major breakthrough in the field of material science. It adopts intelligent material technology, when the waterstop is damaged by external forces and tiny cracks appear, the special ingredients inside the material will automatically undergo a chemical reaction to fill the cracks and restore the waterproof performance of the waterstop. This self-healing feature significantly improves the reliability and stability of the waterstop and reduces the late maintenance costs. In subway projects such as subway tunnels, due to the complex construction environment, the waterstop is susceptible to a variety of external interference, self-healing waterstop can automatically repair the damage without interrupting the traffic, ensuring the normal operation of the project.
Application cases of technological innovation
1. Bridge project: In the construction of a cross-sea bridge, it faces strong corrosive seawater environment and frequent temperature changes. The traditional waterstop is difficult to meet the long-term waterproof demand. A new type of corrosion-resistant waterstop came into being, which adopts a specially formulated rubber material with seawater corrosion-resistant additives, and at the same time optimizes the structural design of the waterstop to increase the bonding force with concrete. In practical application, the waterstop successfully resisted the erosion of seawater, effectively prevented leakage at the bridge expansion joints, ensured the safety and stability of the bridge structure, and reduced the economic losses caused by maintenance and repair.
2. Underground comprehensive pipeline corridor: With the advancement of the construction of urban underground comprehensive pipeline corridor, the waterproof performance and installation convenience of waterstop put forward higher requirements. A new prefabricated assembly waterstop technology has been widely used. This kind of waterstop is prefabricated in the factory, and when it is installed on site, it only needs to be accurately docked with the prefabricated pipeline corridor components and fixed by a special connection method. Compared with the traditional on-site casting of waterstop, the construction cycle is greatly shortened and the construction quality is improved. In a city's underground comprehensive pipeline corridor project, the construction efficiency was increased by 30% after the use of prefabricated assembly waterstop, and after long-term monitoring, the waterproof effect is good, without any leakage.
3. sewage treatment plant: sewage treatment plant pools in the long-term in acid and alkali and other corrosive media environment, the chemical corrosion resistance of the waterstop test is great. The new acid and alkali waterstop adopts a special synthetic rubber material, with excellent resistance to acid and alkali corrosion performance. In a large sewage treatment plant upgrading project, the application of this acid and alkali water stop, effectively solve the pool expansion joints at the leakage problem, to ensure the normal operation of sewage treatment equipment, while reducing the risk of pollution of the surrounding environment.
Technological innovation to bring about changes in the industry
Waterstop's new products and technological innovation not only provides better waterproofing solutions for individual projects, but also promotes the transformation of the entire building waterproofing industry. On the one hand, it improves the quality and safety of the project and reduces the structural damage and security risks caused by leakage; on the other hand, it promotes the improvement of the construction process, makes the construction process more efficient and convenient, and reduces the construction cost. At the same time, with the continuous progress of technology, waterstop products are also in the direction of green development, the use of biodegradable materials or reduce environmentally harmful additives, in line with the concept of sustainable development.
New waterstop products and technological innovation for the construction of waterproofing field has brought new vitality and development opportunities. With the continuous progress of science and technology, I believe that in the future there will be more high-performance, intelligent waterstop products, for all types of construction projects to provide a more reliable, long-lasting waterproofing protection.
