Abstract

The invention discloses a bridge safety-appearance sensing monitoring car and a bridge safety assessment method. The monitoring car comprises a walking car and a detection device, wherein the detection device comprises suspension components and three groups of detection assemblies; the detection assemblies comprise girders, front trolley wheels, rear trolley wheels and detection wheel components; and the detection assemblies are arranged on a walking car chassis in parallel along the transverse direction. The monitoring car and the method have the following beneficial effects that: the safety of the bridge structure can be predicted by only monitoring the bridge deck appearance and curvature changes; according to the law that changes of the bridge deck appearance and bridge deck structure curvature are inevitably caused when the conventional girder bridges and arch bridges have the defects endangering the structure safety, the digitalized curvature surfaces of the bridge deck structure in the test area can be obtained by arranging a bridge deck curvature testing device on the walking car; and the safety of the current bridge structure is distinguished by analyzing and comparing the monitored bridge appearance (bridge deck appearance and bridge deck curvature) changes obtained through previous detections.

Description

technical field

[0001] The invention relates to the field of civil engineering, in particular to a bridge safety-facial perception monitoring vehicle and a safety evaluation method thereof. Background technique

[0002] Bridges are essential facilities for road traffic. Among the large number of road bridges, due to economic, technical, personnel, social and other reasons, some bridges have entered the old age ahead of schedule. In view of the current economic conditions and social needs, these old bridges will still be in use for a long period of time in the future. However, effective monitoring and management measures need to be taken to ensure that these bridges prevent major safety accidents during their use. occur.

[0003] In the prior art, bridge inspections are divided into frequent inspections, periodic inspections and special inspections. Periodic and special inspections of bridges usually refer to using scaffolding or special equipment to go under the bridge for...
