? ? ?A worker must first sharpen his tools if he wants to do his job well. Faced with the challenges of working conditions in these complex and narrow spaces, low headroom equipment can specifically address user needs and solve the construction problems of small sites and low construction heights. At present, the height of most low-altitude environments such as bridges and high-voltage lines is about 6 meters. Our company designs and locates the height of low-altitude equipment for this height.

? ?Cement-soil continuous wall—TRD construction method machine equipment: The report explains the TRD construction method construction principle, the TRD construction method construction technology, the advantages of the TRD construction method, and the application fields of the TRD construction method. In 2012,SEMW independently developed the first domestic 61m Construction capability TRD equipment has formed three major series of TRD-60/70/80 (dual power system), among which the TRD-80E (pure electric power drive) construction method machine has created a world record with a maximum construction depth of 86m. The report introduces the core advantages of TRD construction method equipment in the field of cement-soil continuous wall construction through a number of typical construction cases across the country;Soft foundation reinforcement and foundation reinforcement—large-diameter ultra-high pressure jet grouting rig: Large-diameter ultra-high pressure jet grouting rig was developed to solve the problems of slurry pollution and impact on the surrounding environment in horizontal jet grouting construction. Due to its unique advantages and complex engineering If necessary, inclined, horizontal and vertical construction can be implemented. At present, SEMW?SMJ-120 crawler ultra-high pressure rotary jet drilling rig equipment has formed a modular and serialized construction technology. In order to strengthen the wall strength and anti-seepage performance of underground space and underground pedestrian passages, it has taken into account to ensure that the foundation has been excavated. The wall structure of the pit and the light rail structure of the outer wall use the feature of being small to the surrounding environment to achieve the purpose of reinforcement. It is suitable for poor geological conditions, silty clay, typical soft soil, high difficulty in construction, and small construction space. It is adjacent to the foundation pit wall and the other side is a wall. The advantages are fully displayed in the narrow space construction conditions.

? ? A powerful tool for pile workers in complex construction-full-rotation full-turn tube drilling rig: The full-set tube drilling rig is mainly used for the construction of foundation piles of large buildings such as municipalities and bridges, underground diaphragm walls, pile pulling, clearing, steel column insertion, cast-in-place piles, drilling construction, etc. In the report, the application of a full set of pipe drilling rigs in the Zhuhai Hengqin Hui Tianran Anxin Building Project-the application of a full set of pipe technology in the pile foundation project in a deep foundation pit is taken as an example. The pile foundation is crisscrossed and the space is small. With its compact structure, flexible transition, large clamping force, safety and reliability, simple operation and maintenance, and convenience, it satisfies the construction of the project. The specifications and requirements have been unanimously praised by customers.

? ? New product with low headroom-urban renewal equipment

In addition, SEMW?unveiled a series of new products with low headroom: PJR160 mini-pipe jacking rig, PIT pipe rolling machine, SMD low headroom drilling rig, cast-in-place pile drilling rig and other complete sets of new technologies, in order to become an expert in the overall solution of underground foundation construction. For the purpose of vision, we will comprehensively display the pioneering innovation achievements of the new technology of low headroom construction in recent years by SEMW.

? ? In the conference and exhibition area, our booth comprehensively displays the construction technology and research and development results of a series of products such as underground space equipment, building basic equipment, offshore basic equipment, low headroom equipment, etc., and communicates, learns, discusses, and seeks cooperation with the people who stop by the exhibition.

? ? This year marks the 100th anniversary of the establishment of SEMW. On the road of future development, SEMW?will spare no effort to promote the development of pile foundation construction technology. Hundred years of SEMW, craftsmanship and wisdom, SEMW will be grateful, full of confidence, quality ingenuity, and win-win sincerity, with all the colleagues in the underground foundation construction, efficient collaboration, consistent strategy, and promote China's construction machinery to the world First class.
