Automatic electric measurement type layered settlement instrument

Abstract

The invention discloses an automatic electric measurement type layered settlement instrument. The layered settlement instrument comprises a spliced firm guide rod, wherein multiple grooves are formed in the outer surface of the guide rod; transmission steel wire ropes are laid in the grooves; multiple settlement rings are arranged outside the guide rod; hinges and four anchoring iron sheets are uniformly distributed on the outer sides of the settlement rings; the bottom ends of the transmission steel wire ropes are connected onto the settlement rings respectively; a thin adhesive tape is also arranged on the outer surface of the guide rod; a measurement box is arranged at the top end of the spliced guide rod; a settlement amount electric measurement device and a signal processing and wireless data transmission device are arranged in the measurement box; and the signal processing and wireless data transmission device is connected with a radio transceiver antenna through a feed line and connected with a handheld monitoring instrument through a signal line. The automatic electric measurement type layered settlement instrument is simple in structure; and settling volumes measured by the multiple settlement rings are converted into angular displacements, so that the measurement precision and accuracy are improved. The monitoring precision and sensitivity are high, a signal can be wirelessly transmitted, the transmitted signal is good in anti-jamming capability and high in stability, the numerical values of the settling volumes can be intuitionally displayed in real time, and the layered settlement instrument is simple and convenient to mount and low in use cost.

Description

technical field [0001] The invention belongs to a civil engineering quality monitoring instrument, in particular to a subsidence instrument for long-term monitoring of layered settlement of land soft soil foundation - an automatic electrical measurement type layered settlement instrument. Background technique [0002] In port construction, soft-foot settlement meters are usually used to monitor the layered settlement of soft soil foundations. The working method of the soft ruler settlement instrument is: pre-embed the settlement tube made of PVC material in the soft soil foundation to be tested, and set the settlement magnetic ring in sections outside the settlement tube, and the settlement magnetic ring will settle with the soil layer to be tested. There is a magnetic induction sensor at one end of the tape, and it is connected to the receiver at the other end of the tape through the signal line attached to the tape. There is a buzzer in the receiver, and the scale is marke...

Problems solved by technology

This method requires full manual operation, reading, and recording of measured values.

Therefore, the efficiency is low, observation errors are prone to occur, the measurement accuracy is low, and the data needs to be manually recorded and archived.
