Description
Technical Field
The application relates to the field of bridge performance detection, in particular to a simulation acquisition system for disease data of a bridge expansion joint.
Background
Under the action of factors such as temperature, the bridge expands and contracts longitudinally. In order to meet the requirement of bridge deck deformation, expansion joints are usually provided between two beam ends, between a beam end and an abutment, or at the joint position of a bridge. Bridge expansion joints are the major portion of a bridge that is susceptible to failure during use. Therefore, the real-time monitoring of the health state of the bridge expansion joint is extremely important for timely predicting and diagnosing the fault of the bridge expansion joint.
Traditional bridge expansion joint disease monitoring relies on the experience of managers and technicians to a great extent, and due to the lack of scientific system methods, managers and technicians often lack comprehensive grasp and understanding of the conditions of bridge expansion joints, particularly large bridge expansion joints, and field information cannot be fed back in time. Therefore, a real-time monitoring system is needed for monitoring the health status of the bridge expansion joint so as to monitor the failure in time at the initial stage of the failure and provide an alarm. However, a large amount of bridge expansion joint disease data are needed to be used as experimental data for constructing a real-time monitoring system.
At present, one method uses real bridge expansion joint disease data as experimental data. However, the real bridge expansion joint fault is difficult to customize, so that the real disease experiment data is difficult to collect. The other method is to build a bridge model and simulate the fault condition of the expansion joint on the real bridge. However, in the existing bridge model, few designs specially aiming at the bridge expansion joint exist, so that the existing bridge model cannot be used for simulating the acquisition of the disease data of the bridge expansion joint.

The height and the inclination degree of the whole bridge model are controlled by adjusting the height of each adjustable screw rod 21. The first metal gasket 22 is used for simulating a connection part between a bridge body and a bridge pier in a bridge, namely a bridge support. The first metal gasket 22 is used for connecting the adjustable screw rod and the bridge body (the road approach module 3 and the bridge main body module 5) in the bridge model provided by the embodiment. The adjustable screw 21 is used as a support, so that the stability is ensured, and meanwhile, a slope can be simulated, so that the bridge model is wider in application range and can simulate bridges in various situations.

In one implementation, different numbers of weights are hung at two ends of the first metal wire 63 and the second metal wire 64 to control the motion state of the vehicle model 1 on the bridge model.
In another implementation, another power plant may be used to change the motion state by pulling the vehicle model 1 through the first wire 63 and the second wire 64.
The vehicle model 1 is used for simulating a vehicle running on a real bridge. The vehicle model 1 includes a large vehicle model and a small vehicle model. The large-scale vehicle model simulates a large passenger bus or a large truck passing through a bridge, and the small-scale vehicle model simulates a small-scale vehicle such as a sedan, a light truck and the like.

Referring to fig. 2, a vehicle model 1 that can be used in the present embodiment is shown by way of example. The vehicle model 1 shown in fig. 2 can simulate vehicles with different loads on a real bridge by loading and unloading weights. In the embodiment, the total mass of the aluminum alloy plate is far larger than that of the vehicle model 1, and the requirement that the mass difference between the vehicle and the bridge is large under a real condition is met.
In other embodiments, the vehicle model 1 may also be an electric vehicle model, and no external force is additionally provided for traction. The electric vehicle model has different motion states.
In this embodiment, the expansion joint module 4 comprises a flexible structure 41 (a cross-net structure shown at 4 in fig. 1), and a rigid structure 42 (a gray structure shown at 4 in fig. 1) located at the lower side of the flexible structure 41. In this embodiment, the width of the expansion joint module 4 is set to 5 cm.
Referring to fig. 3, a schematic view of the expansion joint module 4 in the system for simulating and collecting disease data of a bridge expansion joint provided in the embodiment of the present application is seen from above.

Referring to fig. 4, an example of the first metal connecting sheet 421 to which the present embodiment is applied is shown.
Any two adjacent first metal connecting sheets 421 are fixedly connected with one second metal connecting sheet 422 through the fastener 423. The second metal connecting piece 422 is arranged in a direction perpendicular to the first metal connecting piece 421.
As the rigid structure 42 for connecting the bridge main body module 5 and the road approach bridge module 3, the longitudinal and transverse structures of the expansion joint module do not have too strong rigidity, so that the expansion and contraction of the expansion joint module are difficult to embody to extrude the bridge main body module, and the bridge main body module is not firm enough to collapse. The rigid structure 42 satisfies the basic function of the expansion joint module to buffer the displacement of the bridge.
In this embodiment, the flexible structure 41 is implemented by using rubber. Although the rigid structure 42 can fulfill the basic function of damping bridge displacements, if the displacements are too severe, damage may occur to the rigid structure 42 itself. In this way, the flexible structure 41 is arranged above the rigid structure 42, so that the bridge model further buffers bridge displacement due to better extension effect.
In this embodiment, the fastener 423 includes a screw and a second metal washer. In other embodiments, the fasteners 423 may be implemented using other work pieces, such as bolts and nuts.

Can be through the accurate simulation to above-mentioned disease in this embodiment, the required disease data of experiment are accurately obtained.
On the basis of the disease simulation, various disease data are collected, so that the collected data have uniform data forms and clear labels, and the collected data and the data collected when no disease occurs are jointly applied to the construction process of the bridge expansion joint real-time monitoring system.
Since noise above the bridge is large, the road surface condition is more complex, and a fault is more easily found when the expansion joint structure is observed from the bottom of the bridge, in this embodiment, the sensing module is disposed below the bridge main body module 5 or the road approach module 3 and at a first distance from the expansion joint module 4; the sensing module is used for collecting real-time sensing information when the vehicle model 1 passes through the expansion joint module 4.
