Problems solved by technology

[0002] Floods, landslides, rolling stones, earthquakes and other natural disasters, fire, blasting, overloading and other man-made damage, as well as design and construction defects, natural aging of structures and other factors lead to serious damage or even destruction of bridges, causing road traffic interruption, and even interruption of post-disaster life passages, seriously Affect post-disaster reconstruction work or normal economic construction
After the accident, in order to ensure that the traffic can be restored in the shortest time after the accident, the method of building temporary bridges is generally adopted in the prior art for emergency response, and the temporary bridges are generally laid with steel beams and steel plates to bypass the accident bridge; The material is laid now, the work efficiency is low, and it is difficult to adapt to the situation of emergency rescue and disaster relief.
As it is positioned as a temporary bridge, its performance requirements are far lower than those of permanent bridges. Therefore, after the original accident bridge is restored to traffic, because the temporary bridge is built according to the site conditions, the components are often not universal, and the temporary bridge is generally dismantled or abandoned. , resulting in a great waste of cost
In addition, it is necessary to repair or rebuild the original accident bridge, resulting in a great waste of manpower and material resources

Abstract

The invention discloses a ready-package emergency bridge and a construction method for changing the same into a permanent bridge. The ready-package emergency bridge comprises at least two longitudinal beams and bridge road steel plates, wherein the at least two longitudinal beams are parallelly laid; the bridge road steel plates are laid on the longitudinal beams and can limit horizontal and longitudinal freedom degrees; each longitudinal beam comprises longitudinal beam segments which are sequentially fixedly connected along a longitudinal direction; the horizontal longitudinal beams are fixedly connected through horizontal linkage; and the bridge road steel plates are laid on the longitudinal beams in segments along the longitudinal direction. The standard longitudinal beam segments can be combined into the longitudinal beams and the longitudinal beams and the standard bridge road steel plates are combined into a temporary bridge when accidents happen so that the bridge can be fast constructed after the accidents and the traffic of roads are restored within a shorter time to ensure that supplement and supply lifeline can be established in time or normal transportation can be restored after a disaster; in addition, after the emergency temporary bridge is open to traffic, the emergency temporary bridge can be changed into the permanent bridge without maintaining or reconstructing the accident bridge under the condition that the transportation is not obviously influenced, therefore period from the accident to the normal traffic of the road is obviously shortened, and manpower and material resource cost is saved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a quick-installed emergency bridge and a construction method for converting it into a permanent bridge. Background technique [0002] Floods, landslides, rolling stones, earthquakes and other natural disasters, fire, blasting, overloading and other man-made damage, as well as design and construction defects, natural aging of structures and other factors lead to serious damage or even destruction of bridges, causing road traffic interruption, and even interruption of post-disaster life passages, seriously Affect post-disaster reconstruction work or normal economic construction. After the accident, in order to ensure that the traffic can be restored in the shortest time after the accident, the method of building temporary bridges is generally adopted in the prior art for emergency response, and the temporary bridges are generally laid with steel beams and steel plates to bypass th...
