AI Technical Summary

Technical Problem

Existing road settlement monitoring devices cannot accurately capture minute settlement changes, nor can they fully reflect the differences in settlement amount and direction at various points on the road surface. In particular, when there is tilt settlement, single-point measurement methods cannot accurately reflect the settlement situation of the road surface.

Method used

By employing a precise combination of springs, fixed columns, and curved grooves, as well as the linkage design of each component, the vertical and inclined settlement of the road surface can be monitored simultaneously through the rotation of the indicator needle. By utilizing the movable connection between the connecting ball and the connecting block and the rolling characteristics of the monitoring ball on the inclined monitoring disk, settlement changes can be accurately captured.

Benefits of technology

It improves measurement accuracy, accurately reflects the differences in settlement amount and direction at various points on the road surface, meets the needs of engineering scenarios with high requirements for settlement accuracy, and breaks through the limitations of traditional single-point measurement.

Abstract

This utility model provides a road surface settlement monitoring device, including a monitor housing. At least three support frames are fixedly connected to the bottom of the monitor housing. A transparent cover with protective function is fixedly installed at the top opening of the monitor housing. A scale is fixedly connected to the inner wall of the monitor housing. An indicator needle is rotatably engaged in the center of the scale, located between the top of the scale and the bottom of the transparent cover. A monitoring plate is provided at the bottom of the monitor housing, and a monitoring component is arranged between the monitoring plate and the indicator needle. Through the movable connection between the connecting ball and the connecting block, and the characteristic that the monitoring ball can roll on the inclined monitoring plate, the device can simultaneously monitor both vertical and inclined road surface settlement. By observing the rotation of the indicator needle, it comprehensively reflects the differences in settlement amount and direction at various points on the road surface, accurately grasping the overall settlement trend, including changes in road slope caused by uneven settlement.
