Bridge pile foundations are constantly subjected to the scouring action of water flow, which may lead to the loss of soil around the pile foundations and a reduction in the embedment depth of the pile foundations, thereby affecting the stability of the overall bridge structure. According to relevant statistics, bridge safety accidents caused by pile foundation scour occur frequently, causing serious losses to transportation and people's lives and property.

[0025] The present invention provides a bridge pile foundation scour safety monitoring device, including a main body 101 and a precise monitoring component. The precise monitoring component includes a cavity 102, a vertical hole 106, a longitudinal hole 107, a monitor 103, a monitoring rod 104, a fixing bracket 105, a connecting column 108, a water level detector 109 and a monitoring hole 110. Through the foregoing solution, the problems that the direct measurement method is limited by the complex underwater environment, has high operation risk, and cannot perform real - time continuous monitoring, while the indirect measurement method is affected by various factors and is difficult to accurately reflect the actual scour condition of the pile foundation are solved. It can be understood that the foregoing solution is applicable to the bridge pile foundation scour monitoring scenario and can effectively solve the drawbacks existing in the traditional monitoring methods.

[0026] For this specific embodiment, the cavity 102 is fixedly connected to the main body 101 and is located on one side inside the main body 101. The vertical hole 106 is fixedly connected to the main body 101 and is located on one side of the main body 101, and the vertical hole 106 is arranged on one side of the cavity 102. The longitudinal hole 107 is fixedly connected to the main body 101 and is located on one side inside the main body 101, and the longitudinal hole 107 is arranged on one side of the cavity 102. The longitudinal hole 107 is also perpendicular to the vertical hole 106. The monitor 103 is arranged inside the main body 101 and is also arranged inside the cavity 102. The monitoring rod 104 is fixedly connected to the monitor 103 and is located on the side of the monitor 103 close to the longitudinal hole 107, and the monitoring rod 104 is also arranged inside the longitudinal hole 107. The monitoring rod 104 is also perpendicular to the vertical hole 106. The longitudinal hole 107 and the vertical hole 106 are perpendicular to each other. These holes provide a structural basis for the installation and arrangement of the monitoring rod 104 and facilitate the flow of water at the same time. The monitoring rod 104 can transmit relevant information to the monitor 103 according to the changes in the soil around the pile foundation, so as to realize the accurate monitoring of pile foundation scouring.

[0027] Among them, the fixing frame 105 is detachably connected to the main body 101 and is located inside the main body 101. The fixing frame 105 is arranged inside the cavity 102 and is also arranged on the outer surface of the monitor 103. The fixing frame 105 is used to stabilize the monitor 103 and ensure its stable working state in a complex underwater environment.

[0028] Secondly, the connecting column 108 is detachably connected to the main body 101 and is located below the main body 101. The connecting column 108 is perpendicular to the main body 101. The connecting column 108 connects the main body 101 and the water level detector 109, playing a role of structural support and connection.

[0029] At the same time, the water level detector 109 is detachably connected to the connecting column 108 and is located below the connecting column 108.

The monitoring hole 110 is perpendicular to the water level detector 109. The water level detector 109 is used to monitor the water level change in real time, and the function of the monitoring hole 110 is to allow water to pass through so that the water level detector 109 can detect the water level more accurately.

[0030] When using the present invention to monitor a bridge, the monitor 103 and the monitoring rod 104 work together to be able to sense in real time the changes in the soil around the pile foundation, such as information on soil displacement, pressure, etc., and convert this information into electrical signals or other detectable signals and transmit them to the monitor 103 for processing. The water level detector 109 monitors the water level change in real time, providing important data support for comprehensively analyzing the scour situation of the pile foundation. The overall precise monitoring component can relatively accurately obtain the data related to the scour of the pile foundation without relying on underwater operations of divers, solving the problems of danger and inconvenience of the traditional direct measurement method. At the same time, compared with the indirect measurement method, it can more accurately reflect the actual scour condition of the pile foundation.
