Instrument for automatically measuring layered settlement system and measurement and installation method of instrument

Abstract

The invention discloses an instrument for automatically measuring a layered settlement system. The instrument ascends and descends in a general layered settlement pipe through a layered settlement probe of an automatic control instrument so as to measure the position of an outer settlement ring of the layered settlement pipe relative to a pipe opening and record data in real time, and automatic measurement of the layered settlement system is finished. The instrument provides a direct measurement mode, the layered settlement probe directly enters the pipe for measurement, the measurement data are recorded into a control system in real time, monitoring accuracy and real-time performance can be ensured, and errors caused by indirect measurement are overcome. The instrument is reasonable in design, simple in process, easy to machine and low in price of main accessories, so that the automatic measurement instrument has the high cost advantage and is high in applicability, the data transmission modes are flexible and diverse, and installation is easy and convenient.

Description

technical field [0001] The invention relates to an instrument for automatically measuring layered settlement systems and a method for measuring and installing the same, belonging to the technical field of water conservancy engineering safety monitoring. Background technique [0002] In the field of water conservancy projects, settlement monitoring problems of dams, slopes and embankments are often encountered. For example, the settlement stability monitoring of new breakwaters, dams, tailings ponds, etc., all of which require the installation of layered settlement systems. Monitor the settlement of the project to judge the safety status of the monitoring target and guide the construction and management of the project. [0003] The traditional layered settlement monitoring can be divided into two categories: one type adopts the method of manual reading, that is, the traditional layered settlement system is drilled and buried at the design position first. After the system is i...

Problems solved by technology

The first type of method requires at least two workers for each measurement. The on-site workload is large and the efficiency is low. Often due to the different reading habits of the staff, it leads to large artificial reading errors. From the perspective of field application, the reading accuracy of this method is Poor, human influence factors are large, but because the manual reading method is easy to operate, low in cost, and high in maintainability, it is widely used in domestic and foreign projects

The second type of measurement method is easy to measure and has high precision, but the unit price of the instrument is high, the installation of the instrument is difficult, and the working environment of the instrument is harsh. Due to reasons such as installation and later deformation and corrosion, the monitoring instrument is often damaged, which leads to the failure of the entire measurement point. Normal work, high risk of measurement operation, only small-scale applications in some projects
