Abstract

The invention discloses a non-contact soft soil large deformation displacement meter, which comprises a pipe body and a gauge head, wherein a rotary potentiometer is arranged in the gauge head. The displacement meter is characterized in that the two sides of a rotating shaft of the rotary potentiometer are provided with counterweights which rotatably and synchronously move with the shaft of the rotary potentiometer and a first synchronous mobile device; the counterweights and the first synchronous mobile device are located in the pipe body; a second synchronous mobile device are further arranged in the pipe body; the second synchronous mobile device is synchronized with the first synchronous mobile device; a push rod is connected with the lower end of the second synchronous mobile device;and the lower end of the push rod is connected with a mounting pawl. The displacement meter disclosed by the invention has the following advantages that the measuring process is free from construction interruption and artificial measuring error, the measuring range is wide (capable of reaching 1.6m), the precision is high, the measurement is convenient, the construction is safe, meanwhile, the cost is low, and the displacement meter is particularly suitable for the area of the soft soil foundation with large deformation of soil body.

Description

Technical field [0001] The invention relates to a non-contact large deformation displacement meter which can measure the settlement of the foundation. It belongs to the technical field of foundation settlement measurement in civil engineering. Background technique [0002] Settlement observation is widely used in civil engineering construction. The conventional method of foundation settlement observation is mainly to use settlement indicators and precision levelers for manual observation. Manual monitoring methods have disadvantages such as being affected by the construction process and human error. The settlement of the soft soil foundation is large, and the existing deformation sensor has a small range, which cannot meet the needs of settlement observation in the soft soil area. Summary of the invention [0003] The present invention proposes an embedded retractable non-contact large deformation displacement meter, and its purpose is to overcome the above-mentioned defects in ...
