Abstract: To solve the problem that the glass curtain wall under the adjacent super high-rise connecting bridge cannot be cleaned and maintained by window cleaning machine directly from the roof due to the existence of connecting bridge above,the suspension track system can be installed by opening holes under the connecting bridge,so as to realize the daily cleaning and maintenance of the glass curtain wall by window cleaning machine. With the help of the suspension basket,the suspension technology and installation technology of the suspension track system are adopted to successfully complete the construction of the suspension track system. The practical results show that the technology can ensure the safety and reliability of the construction process,the quality can be controlled,and the use of large lifting equipment is reduced. It has the advantages of convenience,rapidity,economy and rationality.
