This project is a supporting project for the 2022 International Winter Olympic Games, located in Chongli District, Zhangjiakou City, the 23# building of the community developed by Chongli Shanshui Tourism Development Co., Ltd. The support area is the east, south and southwest side of the 23# building, 5 m away from the 1F gatehouse and about 5 m away from the southwest road. In order to ensure the safety of gatehouse and road, the excavation slope support construction was carried out.
The maximum difference in height of this slope is 30m, and the slope angle is 60~75°. The anchor cable and lattice beam pouring are all aerial work, which makes the construction operation difficult, and at the same time, the lattice beam horizontal and vertical appearance requirements, engineering safety, civilized construction and quality requirements are high. The project started on August 20, 2020 and completed on September 20, 2020. In 32 days, the construction of support area of 1400 m2 was successfully completed with quality, quantity, safety, civilization and efficiency, No quality accidents, no safety accidents, no fire accidents, no traffic accidents, no group health and hygiene incidents, no occupational diseases and environmental pollution accidents.
After the joint acceptance and inspection of the owner, the design organization, the supervision organization and the construction organization, appearance and quality of the project and construction data are in line with the relevant standards, all to pass.
