Embodiment Construction

[0021] The embodiments of the present invention are described in detail below. Based on the premise of the technical solution of the present invention, the present embodiment provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0022] Such as figure 1 As shown, it is a structural schematic diagram of the monitoring device adopted in this embodiment. In this embodiment, the structural shape of the container 1 is a hollow tube, which is placed inside the concrete structure to be monitored; the hollow tube is filled with gas, and the hollow tube is filled with gas. An extension tube 5 is arranged outside the tube, one end of the extension tube 5 is sealingly connected with the hollow tube, and the other end is an open end, and a liquid column 2 is arranged in the extension tube. The overhanging tube 5 is provided with a scale upper limit 3 and a scale lower limit 4 .

Abstract

The invention discloses a real-time monitoring method and device used for a concrete structure. A container is arranged at the inner part of a concrete structure to be monitored; an outward extending tube is arranged on the container, the container is connected with one end of the outward extending tube in a sealing manner, the other end of the outward extending tube is opened, and gas is introduced in the outward extending tube by the opened end; certain amount of liquid is filled from the opened end of the outward extending tube so as to form a liquid column in the outward extending tube; when the inner part of the concrete structure is subjected to strain, and the volume of the container can be changed, so that the pressure in the tube can be changed, and the liquid column of the outward extending tube ascends or descends finally caused by the change of the pressure in the tube, and the whole changing condition of the structure can be judged according to the up and down floating condition of the liquid column. The invention provides the simple and intuitive monitoring method and device, so that the complicated data collection and analysis can be avoided, and the real-time monitoring expense can be reduced greatly.

Description

technical field [0001] The invention relates to a method in the technical field of civil engineering, in particular to a piezometer for real-time monitoring of concrete structures and a monitoring method. Background technique [0002] Concrete structures need to be inspected or monitored regularly to ensure the safety of the structure. Large strains, large cracks, partial crushing, etc. usually occur before concrete failure, and the detection and monitoring of structures are usually based on the above conditions. At present, most of the instruments used for concrete structure monitoring are monitoring instruments including sensor systems, data acquisition and processing systems, data analysis systems, early warning systems, etc. These instruments are complex and expensive to use, and tiny components, such as Strain gauges are easily damaged under the long-term dynamic load of the bridge, and the signal is easily disturbed and disordered. [0003] Such as the Chinese invent...
