Emergency support unloading and overhauling integrated machine for bridge and construction method

Abstract

The invention discloses an emergency support unloading and overhauling integrated machine for a bridge. The integrated machine comprises a supporting mechanism and a moving mechanism; the supporting mechanism comprises a longitudinal beam, a pair of first transverse beams and two pairs of vertical telescopic supporting columns; the longitudinal beam is arranged in the axis direction of the bridgeto be constructed; one pair of first transverse beams is arranged at the upper part of the longitudinal beam at intervals in the direction perpendicular to the axis direction of the bridge to be constructed; the two pairs of first supporting columns are vertically arranged at the lower parts of the two ends of the longitudinal beam separately; the moving device can move along a pavement below thebridge to be constructed; a lifting part capable of ascending and descending vertically is arranged at the top of the moving device; the top end of the moving device is detachably connected to the bottom of the longitudinal beam; when the supporting mechanism is located on the moving device, supporting columns can not make contact with the pavement; and the moving device moves to the position below the bridge to be constructed, so that the supporting mechanism jacks and supports the bridge to be constructed. The integrated machine has the characteristics of being low in traffic influence, rapid and safe to assemble and capable of being widely applied to the field of bridge emergency overhauling engineering.

Description

technical field [0001] The invention relates to the field of bridge emergency maintenance engineering. More specifically, the present invention relates to a bridge emergency support unloading and maintenance integrated machine and construction method. Background technique [0002] With the rapid development of my country's transportation facilities, the traffic volume has increased significantly, and the traffic density and vehicle load have become larger and larger, resulting in a reduction in the bearing capacity and durability of bridges in some cities, affecting operational safety, and some structures need to be supported and unloaded before they can be repaired When the bridge is partially damaged due to accidental impact, it also needs quick emergency repair. [0003] At present, the maintenance vehicle under the bridge is a relatively common maintenance equipment, but none of them has the function of supporting and unloading. The bridge maintenance vehicle located on ...

AI Technical Summary

Problems solved by technology

[0003] At present, the maintenance vehicle under the bridge is a relatively common maintenance equipment, but none of them has the function of supporting and unloading. The bridge maintenance vehicle located on the bridge deck is an external load that is unfavorable to the safety of the damaged bridge, and the operation is complicated, which has certain potential safety hazards. ; while the maintenance vehicle operation at the bottom of the bridge needs to interrupt the traffic, and it cannot meet the needs of bridges that need to be supported and unloaded for maintenance; the bridge is supported and unloaded by using jacks to support and unload the bridge, but it takes a long time to erect and needs to be closed to traffic, which cannot be achieved. Rapid and emergency characteristics of bridge maintenance under existing traffic conditions
