　　A few days ago, the Shanghai Rail Transit Line 18 10 bid project undertaken by the China Railway 14th Bureau Shield Company was invited to participate in the S26 highway into the city section (G15 highway to Jiamin Elevated) co-sponsored by the Shanghai Municipal Transportation Commission and the Transportation Construction Engineering Management Center Engineering assembly technology application promotion observation meeting, and demonstrated the actual application of assembly technology in project construction. This meeting is also the first publicity of the project after it was listed as a pilot project of assembly technology in the urban rail transit industry in July Debut.

　　At the meeting, the project technicians introduced advanced construction techniques such as chipping treatment at the joint between the cap and the column, grouting at the root of the column, hanging installation of the column, and sleeve grouting to the experts and leaders, and combined the actual application of the project technology. The detailed summary report received extensive attention from the participants and provided detailed and reliable basic information for the application of assembly technology in the field of urban rail transit, and provided strong technical support for subsequent such constructions.

　　It is understood that in recent years, the Shanghai Municipal Transportation Commission has comprehensively promoted the application of prefabricated technology in accordance with the work requirements of the "Shanghai Transportation Construction Prefabricated Technology Application Promotion Plan (2016-2018) (Trial)", and gave full play to the use of prefabricated applications. It has advantages in component production, construction energy saving and environmental protection, safety risk, project quality, etc.

　　Fangxin Road Station is surrounded by residential and industrial mixed areas, with dense buildings and many underground pipelines. Compared with traditional cast-in-place concrete structures, the advantages of prefabricated technology are more prominent. The Shanghai Municipal Transportation Commission comprehensively considered the comparative advantages of the project's surrounding environment, technology application, and the comprehensive strength of China Railway 14th Bureau, and finally determined the project as the first batch of pilot projects in the field of Shanghai rail transit.

　　It is understood that the prefabricated technology only needs to transport the “building blocks”-like components to the site for assembly, which can greatly reduce the large number of on-site construction procedures such as formwork and concrete pouring on site, making the construction more convenient and faster, not only Improve labor productivity, solve seasonal construction problems, and can greatly solve the common problems of traditional wet construction (ie on-site pouring) such as noise, dust, and traffic jams. In addition to high efficiency and environmental friendliness, safety and economy are another major advantage of prefabricated technology. On the one hand, prefabrication can reduce the labor intensity of on-site workers and ensure the safe operation of construction personnel; on the other hand, the quality of prefabricated components is good, and the later The maintenance cost is low. Considering the 100-year project life span, it greatly reduces the project's entire life cost.

　　The construction of this pilot project is the first time that the prefabricated technology has been applied to the internal structure of the station and the structure of the top outlet wind pavilion in the field of Shanghai rail transit. The relevant person in charge of the project department stated that in the subsequent construction work, the detailed rules of the Shanghai rail transit promotion plan will be strictly implemented, the prefabricated technology theory and practice will be combined, the control points of the prefabricated technology in the construction will be summarized, and they will be discovered and studied. Existing problems and solutions, improve the technical support system, improve the quality of prefabricated buildings, promote the transformation and development of Shanghai rail transit, and provide a detailed, reliable, and targeted for the development and application of prefabricated technology in the field of urban rail transit The basic information of the company lays a solid foundation for the widespread application of assembly technology in the Shanghai market.
