A layered settlement automatic measuring device and its measuring method

Abstract

The invention discloses an automatic layered settlement measuring device and a measuring method thereof. The automatic layered settlement measuring device comprises a settling pipe, a plurality of electromagnetic induction magnetic rings positioned outside the settling pipe, a cable gauge, and an electromagnetic induction probe positioned at the head of the cable gauge. The layered settlement automatic measuring device is characterized by also comprising a measurement control box, a synchronous motor, a transmission case connected with the synchronous motor through a coupler, and a wire spoolconnected with the transmission case, wherein the cable gauge is wound on the wire spool; a guide wheel is arranged at the lower side of the wire spool, and the guide wheel is connected with a rotaryencoder; the measurement control box comprises a measurement control module, a motor control module and a power supply. The automatic layered settlement measuring device provided by the invention canrealize high-frequency timing automatic measurement, and high measurement accuracy, can realize unmanned automatic measurement, and greatly reduce the input of human resources, and has a simple structure, fewer movement mechanisms, relatively low input cost, and better economy.

Description

technical field [0001] The invention relates to the technical field of settlement measurement, in particular to a layered settlement automatic measurement device and a measurement method thereof. Background technique [0002] In the past two decades, my country's hydropower projects have made great progress as the basic construction of the national economy. With the construction of a number of high-dam hydropower stations such as Jinping, Ertan, Three Gorges, Nuozhadu, and Xiaowan, and some high-head pumped storage power stations, the demand for soil settlement monitoring during construction is increasing. [0003] At present, the layered settlement measuring device routinely used is an artificial electromagnetic sedimentation instrument, which mainly includes: a coil, an electromagnetic probe, a steel tape measure, a settlement tube, and a magnetic ring pre-buried outside the tube. A scaled steel tape measure with a cable wire inside is connected to the electromagnetic pro...
