Frequent bridge construction accidents are shocking and may be different. The geological, survey, design, construction, supervision and other processes may cause safety accidents in every aspect, but one thing is certain, accident refraction The shortcomings of the safety construction monitoring techniques and means, as well as the lack of construction safety management and supervision. The high-tech content and high-risk nature of bridge construction does not require strong safety awareness, careful safety management and strict safety supervision. Bridge engineering is largely a project to test safety management. Accidents such as collapse are frequent, not only technical mistakes, but also the collapse of security awareness.
1. Regular periodic inspection: including bridge deck inspection, superstructure inspection, and substructure inspection.
Second, the structure of regular inspection: including concrete strength testing, concrete carbonation depth detection, steel bar location and concrete protective layer thickness detection.
Third, underwater component testing: the underwater pile foundation concrete shedding, cracks, exposed ribs, voids, mechanical damage and other diseases were explored and videotaped.
IV. Carrying capacity identification: It is judged whether the bearing capacity of the bridge at this stage can meet the design requirements through the bearing capacity identification.
V. Long-term monitoring point layout and first observation: In order to observe the displacement of the bridge pier and the main beam under the action of the vehicle for a long time, the safety of the bridge is analyzed, the monitoring points are arranged at the key positions of the bridge, and the monitoring points are carried out. First observation.
