Description of the Invention: [Technical Field] The present invention relates to a method for detecting the depth of a bridge foundation, and more particularly to a non-invasive manner of using at least one sensor at a relevant position of a bridge base And with the artificial source to generate down-seismic waves and reflected waves to calculate the depth of the bridge base, to achieve the function of easy to implement, to avoid damage to the bridge base and reduce equipment costs. « [Prior Art] According to the general method for detecting the depth of a bridge foundation, a plurality of parallel holes are drilled at equal distances in the axial direction of one of the side walls of the bridge base, and then most of the sensors are fixedly embedded in each In the hole, an artificial seismic wave is input to the top of the bridge base by using the sag, so that the seismic wave is transmitted to the interface between the base material (concrete) and the ground layer of the bridge foundation, so that the reflected wave is generated due to the change of the impedance. The direct and reflected wave trains estimate the starting position of the reflected wave, thereby estimating the depth of the bridge base by using the waveform change. _ However, the detection method of the conventional method is to fix a plurality of sensor bores in the side wall of the bridge foundation seat, so that the difficulty of construction is improved, and the damage of the structure of the bridge wire base is easy to be caused. Moreover, since the sensors are solidly embedded in the holes, the sensors are often damp due to the change of the river water or the influence of the external environment, which leads to the accuracy of the sensor, and then the accuracy of the sensor is poor. When the detection of the application is applied, it is necessary to sense with a plurality of sensors, and each sensor is costly, thereby causing an increase in equipment costs. SUMMARY OF THE INVENTION The main object of the present invention is to use at least one sensor to be placed at the relevant position of the bridge foundation seat in a non-invasive 201219744 manner, and to generate a downward seismic wave and a reflected wave with the artificial source to calculate the bridge. The depth of the base seat is achieved by the ease of application, avoiding damage to the bridge base and reducing equipment costs. In order to achieve the above purpose, the present invention is a method for detecting the depth of a bridge foundation, comprising the steps of: taking at least one sensor, and placing the sensor on a bridge base, on the side of the bridge base The artificial source is input at different positions, so that the artificial seismic sources respectively generate a downward seismic wave transmitted to the bridge foundation seat, the formation interface, and the downward seismic wave generates a reflected wave due to the group resistance change, and the sensor receives each downlink seismic wave and each The reflected wave is used to estimate the starting position of the reflected wave to calculate the depth of the bridge base. In one embodiment of the invention, the sensor system can be a seismic sensor. In an embodiment of the invention, the sensor can be placed on the ground and in close proximity to the side wall of the bridge base. In one embodiment of the invention, the sensor can be placed on top of the bridge base. In one embodiment of the present invention, two sensors can be further used for use, one sensor is placed on the ground and is closely attached to the sidewall of the bridge base, and the other sensor is set on the bridge. The top of the base. In an embodiment of the invention, the artificial source is generated by a hammer striking an external force of the bridge base. In an embodiment of the present invention, the sensor is further connected to a processing mechanism for performing the calculation of the depth of the beam base after receiving the downlink seismic waves and the reflected waves as the sensor. In an embodiment of the invention, the processing mechanism includes a display unit and an operation unit connected to the display unit. 201219744 [Embodiment] Referring to the "i, 2, and 3", it is a schematic diagram of the basic architecture of the present invention, a schematic diagram of the state of use of the present invention, and a block diagram of the present invention. As shown in the figure: the method for detecting the depth of the bridge foundation of the present invention comprises at least the following steps: 〃 Step-: Take at least - H i, u know ", and the sensor 1 can be further connected - Processing means 2, which comprises a display unit 2 χ and an arithmetic unit 2 2 connected to the display unit 2. Step 2: The sensor 1 is placed on the bridge base 3, and the setting = system can set the sensing Hi on the ground and close to the side of the bridge base 3 i or the sensor i is located at the top of the bridge base 3, and can be taken in two steps! In the system, the sensor i is placed on the ground and the tight shell occupies the side wall of the bridge base 3, and the other sensor i is placed on the top of the bridge base Z. Step 2. At the different positions on the side of the base of the shai bridge, the base 4 is used as the input of the artificial source, and the descending seismic wave is transmitted to the bridge base. 3 The interface with the stratum, and due to the change of the city, the reflected wave is generated by the downward seismic wave. Step 4. The sensor i receives each of the downlink seismic waves and the reflected waves, and transmits the brakes and the reflected waves to the processing mechanism 2, so that the processing mechanism 2 uses the motion=single 2 1 to estimate the reflected waves. The starting position is used to calculate the ice degree of the bridge foundation ^f and the related information of each of the descending seismic waves and the waveform partial state of each reflected wave, the depth of the bridge soil base, and the like are displayed by the display unit 22. In this way, the above steps can be used to replace the conventional detection method with a small number of sensors 1 in conjunction with the 201219744 hammer 4, thereby achieving easy operation, avoiding damage to the bridge base and reducing equipment. The cost of the effect.
