Device and method for real-time monitoring of road and bridge concrete structures

Abstract

The invention relates to a device and a method for monitoring the concrete structure of a road or a bridge in real time. The device comprises a container and a pipe, wherein the container is arranged in the concrete structure and is internally filled with gas; one end of the pipe is connected with the container, and the other end of the pipe extends out of the concrete structure along the horizontal direction; after the other end of the pipe extends out of the concrete structure, part of the pipe body extends along the horizontal direction, and part of pipe body extends downward vertically at the rear end of the part of the pipe body extending along the horizontal direction; a liquid column is arranged in the middle of the pipe; the liquid column is arranged in the part of the pipe vertically extending upwards; the part of the pipe vertically extending upwards is also provided with a scale lower limit and a scale upper limit.

Description

technical field [0001] The invention relates to a real-time monitoring method and device, in particular to a real-time monitoring device and method for concrete structures of roads and bridges. Background technique [0002] With the deepening of my country's reform and opening up and the sustained and high-speed development of the economy, highway bridges, as a key investment and construction industry in my country's economic construction, are developing at an unprecedented scale and speed. Concrete is the main material of modern civil engineering. It can be poured at the construction site according to the design of civil engineers to form any specific shape of the building structure. [0003] Due to various factors such as mistakes in the design, construction and maintenance of highway bridge structures, natural defects in engineering materials, changes in the external environment, increasing traffic volume and load capacity, etc., the bearing capacity of concrete will be s...

Problems solved by technology

However, the real-time monitoring device in this invention also has deficiencies: on the one hand, because its liquid column pipeline is an upward opening, rainwater easily enters during rainfall, causing the impact on the liquid column, and if the opening is closed, the space above it will If the volume is too small, when the liquid column rises, the pressure will increase rapidly, resulting in too little rise and change of the liquid column, making it difficult to observe; Changes in the height of the liquid column will also lead to changes in the height of the liquid column, especially in different seasons, such as summer and winter, the volume change of the gas in the container due to thermal expansion and contraction will also affect the change in the height of the liquid column, thereby affecting the monitoring results
