Inclined angle type scouring sensor and manufacture and installment method thereof

Abstract

The invention discloses an inclined angle type scouring sensor and a manufacture and installment method thereof. The inclined angle type scouring sensor comprises a fixing plate, a U-shaped ring, a chain, an upper shell body, a lower shell body, a guide line, an inclined angle sensing module, a base plate, a sealing plate, a cushion block and a clump weight. In a scouring environment, changes of water flow can drive the inclined angle type scouring sensor to shake, measured inclined angle data change constantly, the state of soil mass is relatively stable, and the measured inclined angle data of the inclined angle type scouring sensor in soil almost do not change. A plurality of inclined angle type scouring sensors are mounted on different depth positions in the same place respectively according to certain intervals, and inclined angle data measured by the sensors are used for distinguishing a water body and the soil mass to determine the position of a mud surface. The position of the mud surface is judged by means of rangeability and frequency of the inclined angle data, and thus the method is not disturbed by temperature variation and other factors. The inclined angle type scouring sensor is simple in structure and convenient to mount, and can change measurement precision and the range of the measurement depth according to using conditions and requirements. Monitoring devices of the inclined angle type scouring sensors are mounted on multiple monitoring places to achieve regional scouring monitoring.

Description

technical field [0001] The invention relates to a water conservancy project monitoring device, in particular to an inclination angle type scour sensor and a manufacturing and installing method thereof. Background technique [0002] In projects such as water conservancy, water intake and drainage, sea and river bank dam protection, bridges, and offshore platforms, it is quite common for structures to be damaged by the erosion of water flow. The strength of the foundation of structures is often reduced due to the erosion of water flow, which brings hidden dangers to the safety of structures. Because the scouring of water is underwater, it is generally difficult to find it in time, and once the structure is damaged due to scouring, it often leads to vicious accidents such as collapse, endangering the property and life safety of the general public. [0003] The current scour monitoring methods mainly include artificial depth gauge, sonar, radar and time domain reflectometer (TD...

The strength of the foundation of structures is often reduced due to the erosion of water flow, which brings hidden dangers to the safety of structures

Because the scouring of the water flow is under the water, it is generally difficult to find it in time, and once the structure is damaged due to scouring, it often leads to vicious accidents such as collapse, endangering the property and life safety of the general public

[0003] The current scour monitoring methods mainly include artificial depth gauge, sonar, radar and time domain reflectometer (TDR), etc., but these methods have great limitations in practical engineering applications, such as offline, low precision, poor stability, cost, etc. It is difficult to monitor the scour status of pile foundation and embankment in real time and accurately
