The design and research of tunnel maintenance lifting platform under the condition of no-traffic
When the diseases of the vault and the waist of the arch occur in the tunnel of the existing express-way,they are limited by the height and often need to occupy the driveway and set up temporary supports to carry out maintenance,but traffic jams often occur in the tunnel,it costs a lot of money and affects people's travel.Based on the working principle of tunnel full-section boring machine and bridge maintenance lifting truss platform,a kind of full-section working platform(referred to as"Maintenance platform")for tunnel maintenance is devel-oped.Through drawing,Solid works,ANSYS and other software,the strength,stiffness and stability characteris-tics of the inspection platform were studied.The results show that the maintenance platform developed in this paper has the following characteristics:first,it has the functions of automatic walking and automatic lifting,and the lift-ing height can be controlled to meet the needs of tunnel daily maintenance,the utility model effectively improves the stability of the maintenance platform and reduces the fear of the maintenance personnel.The second is the light-weight structure,which can be quickly installed and adjusted according to the size of the tunnel structure,bearing capacity is strong,convenient maintenance personnel maintenance,but also improve their personal safety.Third,the road construction,reducing the highway congestion,to better meet the needs of the People's travel.It provides the technical support and the reference for the later popularization and application of the highway tunnel overhaul in our country.
