Problems solved by technology

Due to the special underground environmental conditions, it is extremely difficult to directly transmit information under the soil layer to the ground, which leads to the fact that the steel ruler subsidence instrument still occupies a dominant position in the monitoring of soft soil layered settlement, which hinders the automatic monitoring of soft soil layered settlement development of

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing.

[0015] Such as figure 1 As shown, the sinking magnetic ring of the present invention mainly includes a secondary controller, a power supply, a reed switch and a wireless transmitting and receiving module. The power supply supplies power to the components inside the sinking magnetic ring. As a preferred technical solution of this design, the secondary controller selects an MSP430 single-chip microcomputer with ultra-low power consumption.

[0016] Such as figure 2 , as shown in 3 and 4, before measuring the layered settlement of soft soil, drill holes on the ground and bury the settlement conduit 2 and the settlement magnetic ring, for example, the settlement magnetic ring 1a, the settlement magnetic ring 1b, and the settlement magnetic ring 1c are buried , the MSP430 microcontroller inside the sinking magnetic ring is in an ultra-low power sleep state;

Abstract

The invention discloses a soft soil layered settlement magnetic ring and a settlement monitoring method. The soft soil layered settlement magnetic ring mainly comprises a secondary controller, a power source, a reed switch and a wireless transmitting / receiving module. Information is alternatively transmitted through nodes of the soft soil layered settlement magnetic ring, so that measurement information can be prevented from being restricted by the measurement distance in an underground complex environment, and then soft soil layered settlement can be automatically and precisely monitored.

Description

technical field [0001] The invention relates to the field of measurement, in particular to a soft soil layered subsidence magnetic ring and a subsidence monitoring method. Background technique [0002] When high-rise buildings, highways and high-speed railways are built on soft soil foundations, due to the pressure, the soft soil foundations will undergo compression deformation, which can lead to foundation settlement in severe cases. Therefore, it is of great significance to accurately measure the subgrade before construction. [0003] At present, the method used for soft soil layered settlement monitoring is mainly: before the measurement, the settlement conduit and the settlement magnetic ring are buried underground. , the receiving system will be connected, and then the information will be transmitted to the ground and converted into displacement. Due to the special underground environmental conditions, it is extremely difficult to directly transmit information under t...
