When the gas pipeline vibrates, the heavy hammer fixed at the lower end of the elastic body also vibrates, the force sensor measures the vibration speed of the heavy hammer, and the vibration speed of the gas pipeline is indirectly measured:
assuming that the result monitored by the force sensor is F (t) and the mass of the weight is m, then:
F(t)＝m×a(t)。
in the formula, a (t) is the vibration acceleration of the weight. This value indirectly reflects the vibration acceleration to which the gas pipe is subjected. Integrating the vibration acceleration a (t) over time, the resulting change in vibration velocity to the gas pipeline over time is as follows:

If the time required for the light to travel back and forth between the laser emitting module and the laser receiving module at a speed c in the air is t, the distance D between the two points can be expressed by the following formula:
D＝c×t/2
in the formula, D is the distance between the laser emitting module and the laser receiving module; c is the speed of light; t is the time required for the light to make one round trip.
After the settlement detection module is installed, initial measurement is carried out to obtain the distance D between the laser emission point and the laser receiving point0Along with the construction of the bridge pile foundation, the gas pipeline is downwards settled, and the distance between two points of the laser emission point and the laser receiving point is changed into D after settlementi(i＝0…n)，Di-Di-1The amount of settlement of the gas pipeline per time, Di-D0Is the total settling volume that occurs in the gas pipeline.
The host computer calculates the settlement amount of the available gas pipeline under the construction vibration of the bridge pile foundation through the data signal sent by the settlement detection module, and the real-time monitoring of the settlement amount of the gas pipeline is realized.
In order to accurately monitor the settlement of the gas pipeline, the mean value of the two groups of laser emitting modules and the laser receiving modules is taken as the settlement of the gas pipeline.
(3) The host computer sends the data signal after calculation processing to the removal display end, can look over the settlement volume and the vibration speed of gas pipeline in the bridge pile foundation work progress at any time through removing the display end, reaches real-time supervision's purpose. When the settlement amount and the vibration speed of the gas pipeline reach a certain threshold value, the host immediately sends out early warning to the mobile display end to remind constructors, and the construction safety is further ensured.
