Brief Introduction

  China Railway YanFeng Chengdu Science and Technology Co.,Ltd. invested by China Railway Southwest Research Institute Co.,Ltd which owned by China Railway Group Limited who is a listed company and a fortune global 500 company, is a new- and high-tech enterprise. YanFeng had its origin in a study group of Southwest research institute about Wet Shotcrete technology and was the outcome of transforming scientific and technical achievement into industry.

  The scope of business is engineering mechanism,building materials,environmental protection equipment,electronic product development, production, sales, special professional construction contracting, equipment lease, installation and technical service, technical consultation and technical service for tunnel and underground engineering, test of concrete, selling agent for building materials and electromechanical products.

  Our dominant product is TK series wet rotor piston shotcrete machine and it is very important achievement in scientific research that we entirely hold independent industrial property right. The unique rotor-piston cam feeding system make the continuous feeding and thin flow conveying are available. It won following honors: the 2nd 1998 Science & Technology Advance Prize of the Ministry of Railways, the 3rd 1999 State Technical Invention Prize. In 2010, the TK series wet-shotcrete machines had already been listed among the internal centralized acquisition equipments by China Railway Group Limited Company.

  As the pathfinder of wet shotcrete technology in China,we have talent, product, research, services and so on. The comprehensive advantages can not only provide the after sale service for customer and all-round services including the wet-shotcrete construction technology, proportion of mixture test and optimization, specialized contract.

  In recent years, the company has developed the lining shutter jumbo, full-ring inner-through lining shutter jumbo, inverted arch lining shutter jumbo, stemming machine, concrete admixtures, composit admixture and so on. The main research direction is from the wet-shotcrete technology extended to the tunnel support lining packaged technology.

  Our corporation resolutely adhere to the business principle of |”regarding market demand as the aim, taking innovation as the soul”. We established a domestic unique shotcrete processional laboratory, took dozens of provincial and ministerial level scientific research project, completed a series of sprayed concrete research project, obtained important scientific research achievements in environmental protection type sprayed concrete and high performance sprayed concrete. We have been awarded “advanced high-tech enterprise in Chengdu" in 2002 and awarded "outstanding high-tech enterprise in Chengdu" in 2006. In 2008, we have passed the national high-tech enterprise certification which organized by the Sichuan province.

  Our corporation had achieved certificate of conformity of quality management system certification (ISO9000) in 2003. We promise: YanFeng will develop and product wet shotcrete machine and offer technical service according to quality management system (ISO9001:2008) strictly.
