The rectangular pipe jacking machine occupies a small area during the initial excavation. It is suitable for shallow soil covering and short-distance excavation. It is more economical and applicable than shield machine and has high construction efficiency. During the construction process, technical measures such as attitude measurement and adjustment of pipe jacking machine, surrounding rock grouting and friction reduction can effectively ensure the smooth construction of pipe jacking machine, and provide reference for large section pipe jacking machine in shallow soil construction.展开更多

Due to the complicated constraints after the construction project is put into operation, the TD auxiliary switchyard still needs to continue the hoisting of auxiliary equipment. Large-scale equipment hoisting is a technically difficult project. In the construction process, hoisting equipment, hoisting accessories, hoisting tools, etc. need to be done well to improve the efficiency of equipment hoisting construction. This paper will explore the method of hoisting construction of large equipment.展开更多
