Measuring device and differential settlement real-time detection system

Abstract

The invention provides a measuring device and a differential settlement real-time detection system. The measuring device comprises a liquid container, a liquid level sensor, an electric lifting unit and a measure and control unit, wherein the liquid container comprises a liquid accommodating cavity; the liquid level sensor is arranged inside the liquid accommodating cavity, and is used for collecting liquid level data inside the liquid accommodating cavity; the electric lifting unit is used for lifting the liquid container; the measure and control unit is fixedly connected to the liquid container, and is in communication connection with the liquid level sensor through a first communicator so as to collect liquid level data; and the measure and control unit is further in communication connection with external equipment through a second communicator so as to transmit liquid level data. The system utilizes a plurality of measuring devices, so that an ordered lifting motion is carried outbetween the communicated liquid containers at adjacent measuring points, the liquid level data under the lifting motion is collected respectively, the result whether differential settlement exists between the measuring points is obtained through comprehensive calculation additionally, high-precision, automatic, real-time and continuous monitoring for differential settlement of rails, tunnels, dams, bridges and the like is realized, and powerful technological support is provided for operation safety.

Description

technical field [0001] The invention relates to the technical field of soil settlement measurement and monitoring, in particular to a measuring device and a real-time detection system for uneven settlement. Background technique [0002] Rail transit is favored by the society for its advantages such as fast speed, large transport capacity, and less pollution. Many cities already have urban rail transit, and more urban rail transit is under planning and construction. An urban rail line generally includes different line laying forms such as underground lines, elevated lines and ground lines. Underground structures include circular tunnels constructed by shield tunneling, rectangular structures constructed by open-cut construction, and horseshoe-shaped structures constructed by underground excavations; elevated lines have different structural forms such as continuous beams, simply supported beams, and steel-concrete composite beams; ground line foundations There are constructio...

Problems solved by technology

The manual detection method has the following disadvantages: (1) There are large errors in manual detection, poor continuity and comparability of data before and after, and it is difficult to ensure data stability, especially in bad weather and environments; (2) It is difficult to fully cover the monitoring points (3) On-site maintenance is far away, consuming manpower and material resources, and a large workload; (4) The labor cost rises rapidly, and the labor cost is high; (5) The amount of data is too small, and the test data is difficult to comprehensively evaluate the health of the structure; (6) Difficult to implement when the on-orbit operation time is tight

[0008] The existing static level products are relatively simple to measure and install. The range of measurement is wide, and the accuracy of a single point is generally high, but the accuracy of measuring uneven settlement above 10 meters is low, which cannot meet the technical requirements of construction and maintenance. It is greatly affected by environmental vibrations and is not suitable for vehicles. Real-time detection during motion, easy to damage when overloaded; existing photoelectric detection products are expensive, difficult to install and maintain, not suitable for long-term on-site, when the light is not good, the measurement effect is poor, installation and debugging are complicated, and professionals are needed; existing GNSS products, limited by satellite signals, cannot be used in subways and tunnels, and the accuracy cannot meet the requirements of construction and maintenance standards
