Live report by 'Foundation Engineering' Magazine and Foundation Engineering Network On January 20, 2016, the "Fully Hydraulic Multi-Functional Pile Driver On-site Meeting" organized by Shandong Geological Prospecting Machinery Factory was grandly held in Fenghua. Through on-site observation and exchange meetings, this event perfectly demonstrated the practical application of the LGZ-40 fully hydraulic multi-functional pile driver and led everyone to a deeper understanding of the pile driver expert by your side—Taishan Equipment! 　　This on-site meeting received high attention from industry professionals. Zhang Min, Director of the Construction Division of Shandong Provincial Bureau of Geology and Mineral Resources; Yu Xishun, Director of Shandong Geological Prospecting Machinery Factory; Li Jianguo, Business Director; Hou Qingguo, Chief Engineer; Li Qingbin, Sales General Manager; Miao Hongwen, Project Manager of the Project Department of Zhejiang Xinjie Construction Group; and client representatives of pile foundation construction from all over the country attended and witnessed this grand event.

　　Live Show: Captivating Users' Eyes

 

　　At around 8 a.m. that day, accompanied by leaders and staff of Shandong Prospecting Machinery Factory, all attending representatives went to the construction site for on-site observation and inspection.

　　It is reported that the site is located on Huizheng East Road, Fenghua City, Zhejiang Province, and is a relocation housing project. The proposed main buildings include 11 high-rise residential buildings (11-18 floors), multi-story commercial buildings, a kindergarten, and an overall basement. The site's landform belongs to a coastal alluvial-proluvial plain, and the foundation is below the groundwater level. There are many types of rock and soil, which are relatively uneven and have great property variations. The foundation complexity level is Grade II. The project is contracted by the Foundation Engineering Branch of Zhejiang Xinjie Construction Group.  　　At the site, we saw the Taishan Equipment LGZ-40 fully hydraulic multi-functional pile driver shining under the blue sky, combining good looks with technology. Many users were attracted by such an innovative construction method drilling rig. Some carefully examined the equipment, observing drilling speed, hole formation, and soil output; some consulted in depth with the person in charge of Shandong Prospecting Machinery Factory; some took photos of the construction with their mobile phones... It truly captured the users' eyes!

　　At the same time, attending users fully affirmed and praised the new, more intelligent high-tech products of Shandong Prospecting Machinery Factory.

　　Multi-Function: Leading the Market's High Ground

　　As is well known, pile construction machinery is closely linked to pile foundation construction techniques, and each construction technique requires corresponding equipment to assist in completion. China has a vast territory and diverse terrain, with complex engineering geological and hydrogeological conditions. Various pile types have suitable soil layers and construction needs in China, which provides favorable conditions for the development and innovation of China's pile construction machinery.

　　Under these favorable conditions, in 2009, Shandong Prospecting Machinery Factory actively absorbed and digested domestic new screw pile (HS pile) construction technology, bidirectional short spiral soil-cement injection pile (SDS pile) construction technology, large-diameter long spiral CFG pile construction technology, and large-diameter rotary jet mixing cement-soil pile construction technology. Through independent research and development, the "Versatile Transformer"—the fully hydraulic multi-functional pile driver—matching these technologies came into being and obtained a national invention patent in 2012. After nearly five years of improvement and exploration, the product has become increasingly perfect and mature, and has expanded to various models such as LGZ-25, LGZ-30, and LGZ-40, and is widely used in many engineering projects in Jinan, Dezhou, Fenghua, and other places. 　　The exchange meeting was chaired by Li Jianguo, Business Director of Shandong Prospecting Machinery Factory. Yu Xishun, Director of Shandong Prospecting Machinery Factory; Zhang Min, Director of the Construction Division of Shandong Provincial Bureau of Geology and Mineral Resources; and Miao Hongwen, Project Manager of the Project Department of the Foundation Engineering Branch of Zhejiang Xinjie Construction Group, delivered speeches respectively. 　　Director Yu expressed the hope that users would strengthen exchanges at this meeting, provide valuable opinions and suggestions for the factory, and be full of confidence in making the market bigger and stronger. He said that 2016 is a key year for the factory's development. Our goal is not only to provide the market with machinery products of excellent technology but also to provide customers with the most professional complete solutions for construction technology, maximize satisfaction of customers' demands for construction efficiency and cost control, and truly help customers realize value. 　　Manager Miao introduced that due to the great construction difficulty at this site—10 meters of clay layer and 13-15 meters of pebble layer with a density of 80%—the seven pile drivers initially deployed could only complete 3-4 piles per day on average. The construction effect was not ideal and affected the construction progress. Meanwhile, through various inquiries, the fully hydraulic multi-functional pile driver produced by Shandong Prospecting Machinery Factory can realize the screw pile construction technology. Our side and the factory leaders jointly studied the geological report and believed that the LGZ-40 fully hydraulic multi-functional pile driver was suitable. With the high attention of the factory leaders, the equipment has now been on site for more than 10 days; in the same working time, with a pile depth of 25 meters and a pile diameter of 600 mm, the pile formation efficiency has nearly doubled, effectively ensuring the construction period.
　　In addition, from the comparison of performance characteristics: 1) The power head torque has an absolute advantage; 2) The track width is 900 mm, enhancing balance during construction on soft soil foundations; 3) The electronic control system is simple to operate; 4) Reliable pile quality, no waste soil, no mud circulation, and no influence from groundwater, etc. Therefore, this is the biggest highlight of this on-site meeting.
　　Subsequently, Hou Qingguo, Chief Engineer of Shandong Prospecting Machinery Factory, introduced the technical features of the LGZ-40 fully hydraulic multi-functional pile driver to the users present. He introduced that "this series of pile drivers adopts load-sensitive fully hydraulic transmission, stepless speed regulation, stable transmission, centralized and light operation, safe construction, and high efficiency." These are the most eye-catching performance features. Under the same formation conditions, single-pile hole formation is 15-20 times higher than that of percussion drills and 2-3 times higher than that of rotary drilling rigs. 　　At the meeting, attending users exchanged views on the development direction of pile foundation construction technology and pile foundation equipment, discussed hot issues such as the promotion of screw pile technology and the improvement and upgrading of pile foundation equipment, and proposed cooperation intentions with Shandong Prospecting Machinery Factory. The atmosphere was lively.

　　The successful holding of this fully hydraulic multi-functional pile driver on-site meeting deepened the friendship between Shandong Prospecting Machinery Factory and its users. In the future, the factory will rely on technological innovation that continuously meets market demands, work together with old and new friends, and advance hand in hand to lead the market's high ground!
