In particular, under extreme events such as floods, the ability of bridge piers to resist lateral effects decreases, which will endanger the safety of bridges. Generally, for the scouring detection of bridge piers, manual detection is often carried out by using a probe with a camera device to go deep underwater to record image data. However, since most bridges are built in places with complex and changeable terrain, there will be many loopholes in manual detection, especially for cross-river bridges and mountain bridges trapped by natural environmental factors. Some locations are difficult to reach during manual collection, there are many blind spots, and the collection is not comprehensive. Due to the turbidity of the river or the small number of data collection points, the collected information is single and most of them cannot be used as the basis for evaluation, so the value is low.

[0080] See also Figure 4 , Figure 4 A schematic flow chart of another method for detecting bridge pier scour provided in an embodiment of the present application.
[0081] Exemplarily, after the step of S400: generating a bridge pier over-scour detection result according to the scour depth data and / or the internal flow velocity characteristic value of the river, the method further includes:

[0085] Exemplarily, based on the opening position data of the water flow opening and the water flow velocity data, the force data on the bridge pier to be inspected can be calculated and obtained, and then the pier stability detection result can be obtained based on the force data, so as to judge whether the bridge pier to be inspected is in danger of instability according to the pier stability detection result.
[0086] Exemplarily, S400: the step of generating a bridge pier over-scour detection result according to scour depth data and / or a characteristic value of flow velocity inside a river includes:
[0087] If the scour depth data or one of the scour depth data is greater than a preset threshold, it is determined that the bridge pier over-scour test result fails;
[0088] If the scour depth data and the scour depth data are both less than or equal to the preset threshold, the bridge pier over-scour test result is judged to have passed.
[0089] Exemplarily, the step of obtaining the characteristic value of the flow velocity inside the river based on the float position data and the water level data under the bridge, the calculation formula of the characteristic value of the flow velocity inside the river is:

[0091] Among them, V is the characteristic value of the flow velocity inside the river, H is the water level data under the bridge, Q is the float position data, and g is the gravitational acceleration.
[0092] Exemplarily, the scouring depth of bridge piers and abutments is within a controllable range, which is a prerequisite for ensuring bridge safety; thus, the bridge pier and abutment scouring detection device provided by the embodiment of the present application is arranged on the bridge piers and abutments at the maximum scouring position and nearby, so that the scouring speed of the bridge piers and abutments can be monitored efficiently and at low cost, and the water flow speed at a fixed position can be observed at the same time, so as to provide an early warning for the risk of bridge scouring;
[0093] In the bridge pier scouring detection device provided in the embodiment of the present application, the measuring tube 20 is fixed on the bridge pier 50 to be detected by a circular hoop (ring 41), and can move freely vertically. An end plate mechanism 23 is provided at the bottom, which can be supported or buried in the riverbed. When the riverbed is scoured, the end plate mechanism 23 falls with it;
[0094] A water head sensor (flow rate tube) is arranged on the measuring tube 20 to monitor the flow rate of the river at a relatively fixed depth;
[0095] The development trend of river scouring is monitored by riverbed height, water level and flow rate. When scouring exceeds the predetermined position and the flow rate is fast, an alarm can be issued in time based on the scouring test results of the bridge pier and the stability test results of the bridge pier.
[0096] In some implementation scenarios, combined with Figures 1 to 4 As shown, the bridge pier scour detection method provided by the embodiment of the present application, wherein the measuring tube 20 is installed in the vertical direction of the bridge pier 50 to be detected, and passes through a plurality of collars 41 fixed to the bridge pier 50 to be detected; the measuring tube 20 is located on the riverbed, or partially pre-buried in the riverbed; optionally, the tail wing mechanism 30 is located below the lowest collar 41, and a reflective platform is provided on the top of the measuring tube 20, so that the distance measuring sensor (measuring tube position sensor 12) can measure the pipeline elevation;

[0099] The specific implementation steps are as follows:
[0100] 1. During the sampling period, the data of the float position, the measuring tube position and the water level under the bridge are averaged;
[0101] For example, within a period of time, a series of float position data Q, measuring tube position data G, and underbridge water level data H can be obtained, and sliding averages can be performed respectively to obtain processed float position data Q, measuring tube position data G, and underbridge water level data H;

[0107] Wherein, G is the position data of the measuring tube, L is the length of the measuring tube 20, and D0 is the reference height from the detection component 10 to the riverbed.
[0108] 4. Determine whether the bridge piers are over-scoured and need to be reinforced;
[0109] Set the corresponding depth threshold and flow rate threshold respectively. After the detection result is calculated, if the scour depth data exceeds the depth threshold or the characteristic value of the flow rate inside the river exceeds the flow rate threshold, an alarm will be triggered immediately.
[0110] 5. Determine whether the bridge pier is in danger of instability;
[0111] See also Figure 5 , Figure 5 A schematic diagram of force data calculation provided in an embodiment of the present application, wherein d represents the length between the water flow opening 22 and the bottom of the measuring tube 20, D0 represents the reference height from the detection component 10 to the riverbed, Q represents the position data of the float, v represents the water flow velocity data obtained by the flow tube detection, and d corresponds to v;
[0112] Among them, d corresponds to v, and the water flow velocity at various locations of the bridge pier 50 to be inspected is proportional to the water depth, so the water flow velocity at various locations of the bridge pier 50 to be inspected can be inferred based on d and v; further, based on d, v, D0-Q, the impact force of the water flow on the bridge pier 50 to be inspected can be calculated, and then the corresponding force data can be obtained, and the pier stability detection result can be obtained based on the force data, so as to judge whether the pier is in danger of instability based on the pier stability detection result.
