When Sun Shitong, representative of Doshin Machinery Co., Ltd., and Sun Jinshan, General Manager of China Deep Foundation Engineering Network, met at Jiayou Xincheng, creativity and wisdom burst forth like sparks in their exchange and collision, and will surely ignite fireworks of innovative thinking. Let us look forward together to witnessing the blossoming of a miracle of cooperation!

Jiayou Xincheng — Quality Above All

Beijing Jiayou Xincheng Industry and Trade Co., Ltd. (hereinafter referred to as Jiayou Xincheng) is an enterprise focused on the research and development, production, and trade of foundation engineering equipment and piling tools. Founded in 2003 by the experienced Yang Mingyou, it initially mainly produced piling tools for rotary drilling rigs, such as those of Sany, Xiangyang, XCM, Zoomlion, and Yutong brands. Subsequently, it expanded its business scope to the production of casing oscillators and accessories, including double-wall or single-wall casings, chisels, and grabs. After more than 20 years of exploration and practice in the drilling and foundation industry, Chairman Yang Mingyou is determined to deepen and improve the design of special drilling rigs, enabling the products to win international recognition and acclaim.

Among these, casing drilling equipment and solid mixing equipment have become key equipment for civil foundation engineering and have established a good reputation around the world. Long-term cooperation with domestic professional contractors and overseas enterprises in Asia has secured a place in the international market. Jiayou Xincheng's vision is to become a globally leading foundation equipment manufacturer through continuous innovation, expanded R&D investment, and the development of environmentally friendly equipment. It is committed to providing customers with high-quality products and services and to continuously enhancing its corporate strength, scope of application, and application fields to meet customer needs. At the same time, it emphasizes technological innovation and quality management, continuously improving product technical levels and quality standards to ensure product reliability and stability. Jiayou Xincheng has always adhered to the business philosophy of "sincere cooperation, quality above all," striving to create greater value for customers and to promote the development and progress of the foundation engineering industry.

AFE Series Casing Rotator — Design Features

Jiayou Xincheng's AFE series casing rotator, with its unique three-jaw clamp design, achieves automatic centering of the casing and provides ample clamping force. It adopts advanced computer simulation technology for mechanical and structural optimization design, successfully avoiding structural interference and lifting-impact phenomena during operation and ensuring a stable and reliable construction process. The machine is equipped with two pump station systems—electric motor and diesel engine—for customers to choose flexibly according to their needs. Manual and remote-control operation modes can be easily switched, enhancing operating convenience. It is widely used in urban infrastructure, railways, ports, hydropower, and other fields, successfully handling various complex strata such as cobbles, silt, and quicksand, providing all-round assurance for construction and demonstrating its superior performance and diverse applicability.

AMP Fully Automatic Environmentally Friendly Mud Preparation System — Technical Optimization

The AMP fully automatic environmentally friendly mud preparation system plays multiple key roles in construction. First, as flushing fluid or stabilizing fluid, it stabilizes the borehole wall and carries and suspends drill cuttings, improving work efficiency while protecting the borehole wall. Second, through the cooling and lubricating effects of the mud, the drill bit is protected and wear is reduced. In addition, the mud forms hydrostatic pressure in the hole, stabilizing the borehole wall and preventing collapse. In strata with permeability, the mud can effectively form a filter cake, preventing leakage and achieving a wall-protection effect. At the same time, the circulating mud carries drill cuttings out of the hole, reducing wear on drilling tools and improving drilling efficiency. Finally, the dynamic expansion property of the mud can seal impermeable zones of oil reservoirs, ensuring the smooth passage of the drill bit. These functions demonstrate the multifaceted functions and value of mud.

High-Speed Mixing, Solidification, and Hydraulic Fill of Silt — Treatment Technology

Chemical solidification treatment technology, by adding curing agents, promotes a series of hydrolysis and hydration reactions between the mud and the curing materials to form cementitious substances, enhancing the stability and water stability of silt particles. These hydration products form a network structure that fills pores and gives the silt structural strength, making it an ideal treatment method for organic waste. This method can not only effectively reduce the moisture content of silt and lower the activity of pollutants, but also meet engineering strength and permeability requirements, playing a role in pollution reduction. Chemical solidification treatment technology is suitable for large-scale projects, is simple and quick to construct, and allows the curing agent to be adjusted as needed. In addition, using industrial waste as auxiliary curing material can reduce project costs, achieve energy conservation and emission reduction, and deliver both economic and environmental benefits.

During the visit to Jiayou Xincheng, one deeply felt that Jiayou Xincheng has always upheld a demanding pursuit of quality and innovation. The company not only produces foundation engineering equipment and piling tools, but also focuses on providing customers with outstanding products and services. In exchanges with Senior Engineer Yang Mingyou, it was learned that the company will continue to drive technological innovation and tirelessly improve product quality, aiming to become a globally leading foundation equipment manufacturer. Jiayou Xincheng's persistence and efforts have already gained recognition in domestic and international markets, earning the company a good reputation. This visit not only provided a deeper understanding of Jiayou Xincheng, but also conveyed their steadfast pursuit of and unremitting efforts for industry development. With its continuous pursuit of quality and innovation, Jiayou Xincheng is gradually establishing an internationally leading position and bringing new development opportunities to the foundation engineering industry.
