Embodiment Construction

[0020] A new method of monitoring the strain in the shallow crust is to bury the stress sensor in the sand in the shallow crust instead of installing the stress sensor in the deep bedrock borehole or directly burying the stress sensor in the shallow crust in soil or rocks.

[0021] The technical scheme adopted in the present invention ( figure 1 ):

[0022] First dig a deep pit on the surface (1-1) soil layer (1-2), and build a safety protection shaft (1-3) in the pit. The safety protection shaft (1-3) is used to prevent water seepage into the well and prevent the shaft from The side walls collapsed. The stress sensor (1-5) is buried in the sand (1-4) under the safety protection shaft (1-3).

[0023] Safely protect the wellhead of the well shaft (1-3), leave an entrance and exit for maintenance, prevent wind and rain, prevent water ingress, and build a well room or well cover.

[0024] The requirements for the soil layer are: ① the soil layer below the permafrost layer, ② ...

Abstract

The invention provides a novel method for monitoring strain on an earth crust shallow layer. Practice proves that the strain on the earth crust shallow layer is related to an earthquake precursor, so that the method is a novel method for monitoring the earthquake precursor. By the method provided by the invention, the characteristics of particle media are used, a stress sensor is not arranged in a drill hole of a bed rock on an earth crust deep layer but is embedded in sand of the earth crust shallow layer, and water around the stress sensor is displaced into clean water for washing sand in spite of an earth surface soil stratum or an earth surface bed stratum. The stress sensor is buried below a frozen soil layer and above an underground water level.

Description

technical field [0001] The invention provides a new method for monitoring the strain in the shallow layer of the earth's crust. Practice has proved that the shallow crustal strain is related to earthquake precursors, therefore, it is a new method for monitoring earthquake precursors. Background technique [0002] my country is one of the earthquake-prone regions in the world, and the earthquake has caused great losses to the lives and properties of our people. [0003] The current theory of earthquake genesis holds that the earth’s crust is composed of the lithosphere, which is divided by several major plates. Due to the movement of plates, a large amount of energy is accumulated (or accumulated) in the lithosphere, and the force generated by this energy causes the lithosphere to deform. , Earthquakes are caused when the lithosphere fails to withstand the enormous force and ruptures. According to the current theory, the deformation of the lithosphere can only be better tra...
