"Workers must first sharpen their tools if they want to do their job well". The development and progress of society is accompanied by the progress of the use of tools, from clumsiness to wisdom, from simplicity to integration. Especially in the fields of engineering and construction that are related to people's livelihood. Good equipment and good materials can create better buildings and better roads. At this point, Shantui Jianyou is a "practitioner" who is brave in innovation.

Bai Yu is deservedly deserved

At the "2020 China Construction Machinery Annual Product TOP50 Award Ceremony" held on April 16, Shantui Jianyou UHPC's complete mixing equipment won the "China Construction Machinery Annual Product TOP50 Award", demonstrating the excellent quality of Shantui Jianyou Mixing Station .

As a kind of ultra-high performance concrete, UHPC breaks through many limits of cement-based material performance and application fields, has excellent wear resistance and anti-explosion performance, and is very suitable for large-span bridges, anti-explosion structures and thin-wall structures, etc. It can be called the most durable engineering material. With the increase of national key engineering projects and the local government's great emphasis on project quality, UHPC has become an indispensable element in helping bridges and engineering construction.

Shantui Jianyou UHPC mixing equipment is a complete set of mixing equipment for producing high-quality UHPC materials. It adopts UHPC asymmetry special vertical shaft mixing host, steel fiber conveying and weighing system, and module design, which can realize long-distance monitoring of the entire production process and the situation of each part, and timely tracking and solving problems. It is not only simple and convenient to operate, but also very dexterous in design. The vertical shaft mixer can be installed and arranged on various types of production lines, giving full play to its own advantages.

The most important thing is that Shantui Jianyou UHPC mixer produces ultra-high-performance concrete with controllable mixing uniformity, which has excellent characteristics such as ultra-high strength, high toughness, high elastic modulus and micro-crack self-healing ability. Coordinate with the environment to shorten the construction period and create greater economic benefits for the construction party. This set of equipment not only enables green construction, but also has realized the transformation of UHPC concrete from small batch manual operation to large batch automated production, and has obtained multiple invention and utility model patents.

With these superior technologies, Shantui Jianyou UHPC mixing plant has made great achievements in the construction of Nanjing Five Bridge and Zhengwan Railway, and the Middle Road Dura Project, which has been highly praised by users.

Extraordinary products, take great responsibility

In 2019, the construction of a large-scale bridge project, the Nanjing Yangtze River Five Bridge, began, with a total UHPC consumption of 11,670m³, which is the largest UHPC bridge project in the world to date. In this major project, Shantui Jianyou UHPC mixing equipment is the main force of UHPC quality material manufacturing in this project, which has undertaken a total of 55% of the production capacity, and has carried out UHPC wet joint connection, superimposed connection with steel box beams, etc. Innovation. In this project, Shantui Jianyou ’s UHPC complete mixing equipment produced UHPC components reflecting high automation production levels, production efficiency and quality control capabilities.

In China, steel-UHPC composite decks are widely used. This is because UHPC is used to pave bridges. It is a worldwide approved method of bridge repair and reinforcement. It can improve the strength, stiffness, crack resistance and waterproof characteristics of bridges, thereby improving the service life of bridges. In this respect, Shantui Jianyou UHPC mixing equipment can provide excellent solutions, and the use of Shantui Jianyou UHPC wet joints to connect PC components of prefabricated buildings, bridges or other structures can improve the quality of node connections. , Performance and reliability, to achieve "strong nodes, weak components" assembly structure, and reduce the difficulty and cost of on-site construction, with both technical and economic advantages.

After 20 years of research and application, the application scale of Chinese UHPC in steel bridge deck pavement and steel-UHPC composite bridge has been at the forefront of the world. The steel-UHPC composite beam produced by Shantui Jianyou's complete equipment has also made significant progress in the innovation and application of bridge structures in China, and it has been shown in many national key projects.

Looking into the future, widely used

In addition to the bridge application, Shantui Jianyou UHP mixing equipment has performed well, and in construction projects, especially in the construction of UHPC, such as exterior decoration, stairs, wall panels, prefabricated insulation wall panels, beam-column joints, etc. Brilliant. For example, the thermal insulation wall panel produced by this set of equipment not only has a reasonable design, but also can obtain economic benefits from reducing the weight of components, reducing the overall weight of the building, and reducing the cost of transportation, hoisting, installation and construction. Moreover, the combination of such components and prefabricated steel structure buildings can form a complementary assembly building system.

In addition, reinforcement construction is also a very important application. In many provinces and cities of the country, there are a large number of bridge aging problems. There are also defective or aging concrete structures such as wharfs, tunnels, water conservancy and hydropower, and buildings. Replacement, in these respects, Shantui Jianyou has also carried out research and application of UHPC maintenance and reinforcement.

Many successful application cases show that Shantui Jianyou Ultra High Performance Concrete (UHPC) complete mixing equipment, with high innovative equipment, solid technical background and rich construction experience, can always produce high-quality UHPC according to the requirements of the demand side .

As a material with better performance, UHPC can meet the high requirements of social construction on product quality, engineering durability, maintenance, green and low carbon, and low resource consumption. Shantui Jianyou UHPC's complete set of mixing automation equipment is committed to promoting UHPC's innovation and technological progress, and as a new engine for UHPC's development, it promotes the industry's development in the direction of high quality and environmentally friendly.Editor / Duan Wenyan
