On March 1, State Grid Lianyungang Power Supply Company, relying on its self-developed high-performance nanoconcrete materials, developed a porous, lightweight offshore photovoltaic bearing platform that can be applied to offshore photovoltaic projects. This is another achievement of the company in the field of high-performance nanoconcrete lightweight power components development.
For the transmission and distribution project concrete precast components in saline and alkaline land and other environmental applications in the volume of bulky, difficult to maintain, easy to corrode and other issues, since December 2021, Lianyungang Power Supply Company organized equipment, science and technology and other relevant departments and affiliated industry construction, design units, technical backbone, joint colleges and universities, intellectual property rights consulting units, etc., set up a nano-cast precast project research and development team, to The R&D team of nano prefabricated components project was established jointly with universities and intellectual property consulting units to carry out the R&D of high-performance nano prefabricated components in the mode of "industry-university-research-use".
In response to the core problem of raw materials, the R&D team has carried out many rounds of proportioning experiments on a dozen of materials, and comprehensively considered the subsequent production costs, etc., and in September 2022 developed a new high-performance nanoconcrete material that is corrosion-resistant, tough, and green.
According to reports, the material is made of nanoscale active microsilica powder made of cement with minerals, fibers, admixtures, etc. Proportionally mixed to effectively improve the fineness of raw materials and activity, compression of pore space and microcracks, compared with traditional materials with ultra-high strength, high corrosion resistance, low porosity and very low permeability, the industry is called can be applied to the power grid construction project of the "Liquid Metal It is called "liquid metal" in the industry which can be applied to the power grid construction project.
"Prefabricated components made from this new high-performance nanoconcrete material have strength and tensile properties equivalent to four and six times that of ordinary concrete, with an ultimate strength of up to 35 times. At the same time, under the same load-bearing requirements, the weight of the product components can be reduced by more than 75% compared with ordinary concrete." R & D team project implementation full-time Zhai Yong said.
In June last year, located in Lianyungang, a saline land of the Yunting waterfront community substation construction, originally required 15 workers to complete 28 days of on-site pouring of concrete construction changed to prefabricated building assembly method, only 5 workers 12 days to complete. At the same time, thanks to the high-performance nanoconcrete made of lightweight electric components in the cable strip, inspection wells, high-voltage branch boxes and other foundations of the application of the materials used in a single project than the traditional way to reduce the number of about 12 tons.
On March 1 this year, Lianyungang Power Supply Company further innovated and expanded the application scenarios of prefabricated components on this basis, and developed a porous and lightweight offshore photovoltaic bearing platform that can be applied to offshore photovoltaic projects, which can help to solve the problems of concrete pouring and maintenance in offshore photovoltaic projects.
Up to now, the high-performance nanoconcrete lightweight power components developed by the company have been applied in more than 30 power engineering projects such as distribution of agricultural networks, home distribution, users, etc., with an average reduction in the comprehensive cost of the project of about 10%, an overall reduction in solid waste and garbage emissions of about 70%, and a reduction in carbon dioxide emissions of nearly 60%.
