: 180-6251-5888 When the bridge bearing is damaged, it is usually necessary to replace the bridge bearing
At this time, the beam body needs to be jacked up for replacement
Shijiazhuang 21m bridge inspection car rental divides the whole jacking process of replacement bearing into five steps: pre jacking, weighing, jacking, load holding and beam falling in place 1
Pre jacking Pre jacking is to effectively connect various systems and eliminate the inelastic deformation or settlement of the support itself
During this period, the effective connection of various systems is reflected in these aspects: there is no oil leakage and falling phenomenon of hydraulic cylinder, high-pressure hose and various joints, the main normal indication of instrument section and no abnormal deformation of jacking foundation 2
Weighing Weighing is to determine the practical load pressure required by the jack at each jacking point to ensure the safety of jacking
Due to the influence of swing data, structural part correction and temporary structure, the actual weight of bridge structure is usually quite different from the design value, which will cause safety problems for jacking engineering 3
Jacking Jacking is divided into trial jacking and formal jacking
Trial jacking is to check the safety of the jacking system, the safety of all jacking of the bridge and the authenticity of weighing results
When the No
bearing is replaced, because the displacement of the bearing required to be jacked is not exactly the same, in order to prevent the tilting scene in the jacking process and ensure the stable and safe jacking of the beam, the jacking displacement of the beam body is usually completed gradually according to a certain jacking displacement 4
Load holding Load holding is a situation in which the temporary jacking is maintained due to the construction needs after the jacking is completed, so as to keep the jacking orientation unchanged after the jacking is completed
When the support is replaced, the self-locking organization of the hydraulic system is mainly used to keep the jacking orientation unchanged during the load holding period
The self-locking organization selects the hydraulic one-way valve
The manufacturing accuracy and tightness of the hydraulic components used in the selected hydraulic equipment are the main reasons for determining the load holding accuracy and large load holding time 5
Beam dropping The falling beam can be regarded as the lifting process
Compared with the lifting of bridge beam, the falling beam receives the same load and the lowering method is also similar, but the displacement direction is opposite Xingtai 22 meter bridge inspection car rental company has rich experience in bridge construction, has undertaken large-scale bridge inspection and maintenance projects for many times, and has safe service, which is highly praised by our customers
