Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0015] The structure of the magnetic scour sensor is as follows: figure 1 As shown, the sensor includes 1 natural stone or concrete prefabricated block; 2 ferromagnetic material and 3 cement mortar or epoxy resin. The connection and production method between the components of the magnetic scour sensor is as follows: firstly, according to the specific test distance and accuracy requirements, determine the shape and size of the natural stone or concrete prefabricated block and the embedded ferromagnetic material. The ferromagnetic material is a magnetic block or iron One of the blocks; after that, make natural stone or concrete prefabricated blocks, and open a stepped groove with a large surface opening and a small internal opening on the surface of the natural stone or concrete prefabricated blocks. At the same time, grind ...

Abstract

The invention discloses a magnetic prospecting-based erosion monitoring method, which belongs to the technical field of structure safety monitoring. The method is characterized by comprising the following steps of: manufacturing a magnetic erosion sensor with self-sensing features by directly embedding a ferromagnetic substance serving as a sensor element into a natural stone or a concrete precast block and encapsulating the ferromagnetic substance; structuring an erosion monitoring system by compounding the sensor and a magnetometer; when monitoring erosion, prearranging or throwing the magnetic erosion sensor together with protection riprap together in an area of which a structural base is easily eroded; detecting the position change information of the magnetic erosion sensor by adopting the magnetometer; and monitoring the erosion state of the structural base in real time. The method has an effect and an advantage of avoiding an influence on structure erosion monitoring caused by severe environmental factors such as silt stratification thickness, flood and the like, and has the outstanding advantages that the method is simple in operation, the test precision is high, the performance is stable and the like, and can be widely used in structure erosion monitoring and protection of major projects such as reservoir dams, river dikes, bridge and ocean platforms and the like.

Description

technical field [0001] The invention belongs to the technical field of structural safety monitoring, and relates to a method for monitoring erosion of civil engineering structures based on magnetic exploration. Background technique [0002] Scouring is one of the important causes of damage to major engineering structures such as reservoir dams, river embankments, bridges and offshore platforms. Flood disasters are the most harmful and costly disasters in my country's natural disasters. As an important part of the flood control engineering system, the safety status of reservoir dams and river embankment projects is directly related to the safety of people's lives and property along the project, as well as national economic development and social stability. However, due to the limitations of natural, social and economic conditions, the existing reservoir dams and river embankment projects in my country still have shortcomings such as poor dam / dike foundation conditions, serio...
