At the start of the new year, all things take on a new look. The 2017 National Science and Technology Awards Conference opened at the Great Hall of the People, where Party and state leaders attended and presented awards to researchers who received the State Preeminent Science and Technology Award, the State Natural Science Award, the State Technological Invention Award, the National Science and Technology Progress Award, and the International Science and Technology Cooperation Award. A total of 271 projects and 9 science and technology experts were selected at the conference. 　　As a main completer and completing unit of this award, Shanggong Machinery first thanks the expert team that jointly participated in this technological research and development for its leadership, and all major foundation construction units for their joint efforts. The achievements are the crystallization of everyone's collective wisdom. 　　As the scale of underground space development grows larger, deeper, tighter, and more complex and changeable, it provides a broad stage for the application of new support technologies in deep foundation pit engineering. The steel-reinforced cement-soil mixing pile (wall) support structure must meet the needs of "depth, speed, and strength," cut off or partially cut off the hydraulic connection between confined aquifers and deep foundation pits, control excessive ground settlement caused by foundation pit dewatering, ensure the safety of deep foundation pits and the surrounding environment, and solve the difficult problem of constructing cement-soil mixing piles in confined aquifer depth ranges and dense sand layers in deep foundation pits.
TRD construction method technology has become a new foundation pit support construction technology available for selection. 　　As a domestic professional manufacturer of TRD construction method equipment, Shanggong Machinery has two models, TRD-D and TRD-E. Choosing Shanggong TRD construction method machines can meet the following requirements: (1) Energy-saving and environmentally friendly. While ensuring the same wall thickness and depth, cement consumption is saved by about 15%, and the overall project budget cost is reduced by 18%. Under the same conditions, the spacing of inserted core materials can be set arbitrarily, achieving efficient savings. (2) Good wall quality. Compared with traditional methods, the TRD construction method machine performs all-round mixing to form a continuous equal-thickness cement wall of uniform quality. In the depth direction of the wall, the cement-soil is uniformly mixed, with high strength, small discreteness, and good seepage resistance. (3) Wide application. Compared with traditional methods, the TRD construction method machine has a lower body height, can be constructed adjacent to buildings, has small vibration amplitude, high safety, and good passability.
　　In summary, the Shanggong Machinery TRD construction method machine is green construction method equipment for sustainable development and a circular economy.
　　In addition, the Shanggong Machinery TRD maintenance agreement provides one-stop service: patrol maintenance during TRD on-site construction to ensure normal equipment operation; overhaul and maintenance after project completion to lay a good foundation for the next new project; leak-checking and gap-filling maintenance during equipment relocation to help the equipment eliminate hidden dangers and ensure immediate construction at the new site; even if the equipment is completely normal, engineers from the technical service department will also make regular visits to help customers eliminate all potential risks and ensure that customers can have complete peace of mind at every moment they own the equipment!
