We will use our professionalism to help our customers and friends solve the problems of bridges, so the rental of Jinzhou 18m bridge inspection car is yours Bridge bearing is an important structural component connecting the superstructure and substructure of the bridge
It is located between the bridge and pad stone
It can transfer the load and deformation (displacement and angular rotation) borne by the superstructure of the bridge to the substructure of the bridge
It is an important force transmission device of the bridge
Matters needing attention when replacing the bridge bearing Boshi Equipment Leasing Co
, Ltd
has sorted out the following: 1
Place sleepers into a platform
All sleepers shall be of uniform size and staggered so as to bear uniform force
The bearing platform shall be fully paved on the bearing platform surface, and the tie beam shall be mainly expanded to the soil surface layer at the tie beam
It shall be widened outside the column to ensure that there is enough position for jacking equipment at the upper part 2
Before the replacement of bridge bearings, the temporary stress structure shall be considered according to the actual geological conditions of each pier (abutment), and the earthwork stacked on the bearing platform and lower tie beam shall be excavated manually with a small excavator, so that the bearing platform and tie beam can be exposed and the support can be erected; There is no available cushion cap and tie beam
When the geology is good, the temporary bearing foundation can be built
When the geology is poor, the column can be used as the temporary bearing structure 3
During jacking, the local concrete of the beam body will not be damaged
When jacking the beam body, the jacking force generated by the large tonnage jack applied due to the self weight of the beam body will be greater than the compressive strength of the concrete on the local unit area of the beam body, so it will cause local crushing of the concrete and affect the integrity and quality safety of the beam body 4
After the support, working platform and Jack are installed, the roof test shall be started after the temporary load-bearing foundation meets the requirements; The jacking test is mainly to eliminate the inelastic deformation or settlement of the support itself
It can be stopped when the main beam has not been officially jacked up and parked for 2 hours for observation
The overall jacking can be started only after there is no change
The stress direction of the jack must be perpendicular to the hollow slab surface 5
Establish the observation system
The jacking system is simpler and more intuitive than a single mechanical model, so the stress-strain gauge is not used for monitoring, but two personnel must be sent to observe the beam body during the jacking process
Once a problem is found, the jacking shall be stopped immediately, and the jacking shall be carried out after the problem is solved 6
Prevent the damage between members caused by the longitudinal sliding of the beam body
Due to the small scale of the bridge, the bridge deck system will not be affected when the bridge support is replaced according to the guidance of the bridge construction party Jinzhou 18m bridge inspection car rental shall try to meet the inspection needs of the construction unit within the scope of operating procedures and use requirements, and provide a fast and convenient operation platform for the majority of bridge inspection and measurement units, bridge and tunnel construction units and maintenance units
