Problems solved by technology

At present, the more common practice is to monitor the stress and strain of the soft soil foundation before and during the construction process manually, so as to find potential safety hazards.
The inventors found that due to the unpredictability and randomness of the occurrence time of geological disasters and the long-term potential of site hazards, long-term field observations on the site are susceptible to external interference and are time-consuming and laborious. The errors in the observation data are relatively large. make it quite difficult to realize

Embodiment 2

[0042] Such as Figure 4-Figure 5 As shown, the present embodiment discloses a behavior monitoring system for muddy soft soil foundation of coastal highway, including a plurality of monitoring devices for muddy soft soil foundation of coastal highway described in Embodiment 1, the pore water pressure sensor, earth pressure Sensors, resistive displacement sensors and inclination sensors are connected to the data acquisition terminal. The data acquisition terminal can be an existing data acquisition terminal. The data acquisition terminal is based on GPRS, CDMA, 3G / 4G, satellite and other wireless communication networks to realize remote The intelligent terminal equipment for data collection and transmission can easily realize the connection of things or human-computer interaction, and has the functions of data storage, comparison, analysis and processing, and is widely used in remote measurement and control systems. Preferably, the data collection terminal adopts AX-F60(EX) dat...

Embodiment 3

[0046] This embodiment discloses the working method of the muddy soft soil foundation performance monitoring device of coastal highway described in embodiment 1, including the following steps:

[0047] Embed the support pipe and the base in the soil. During the embedding process, the support pipe and the surrounding soil have a set distance of 2cm-3cm to reduce the system error caused by friction. The end of the settlement mechanism is buried in the In the soil, the settlement mechanism can move synchronously with the soil.

[0048] When the soil layer settles, the settlement mechanism slides down along the support tube with the settlement of the foundation soil, driving the resistance probe connected to the sliding part of the settlement mechanism to slide down on the resistance bar. The resistance bar is inside the support tube and only through the resistance The probe is connected to the subsidence mechanism, and the subsidence mechanism slides down along the support pipe w...

Abstract

The invention relates to a performance monitoring device, system and method for muddy soft soil foundation of coastal highway, including a support pipe, which is connected to the base in rotation, and the support pipe is equipped with an inclination detection piece, a resistive displacement sensor, and a resistance bar of the resistive displacement sensor Extend into the inside of the support tube and contact the resistance probe, the resistance probe is fixedly connected with the settlement mechanism, the settlement mechanism includes a sliding part located inside the support tube and the diameter is smaller than the inner diameter of the settlement tube, the sliding part is provided with multiple ends, and the ends pass through The guide groove provided by the support tube protrudes to the outside of the support tube and is equipped with a pressure detection part. The width of the guide groove is larger than that of the end part. The monitoring device of the present invention saves time and effort, and the monitoring result is accurate.

Description

technical field [0001] The invention relates to the technical field of monitoring equipment, in particular to a monitoring device, system and method for muddy soft soil foundation properties of coastal roads. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The silty soft soil of the coastal road has the characteristics of high compressibility, low strength and poor water permeability. Therefore, when building roads in this area, how to accurately grasp the real-time behavior of the roadbed is of great importance to ensure safe construction, post-construction settlement and safe operation of the road. significance. At present, the more common practice is to monitor the stress and strain of the soft soil foundation before and during the construction process manually, so as to find potential safety hazards. The inventors found that due to the unpred...
