The invention provides a device and system for measuring internal displacement of concrete and an installation method of the system. The device comprises a casing, a spring, a probe and a bushing, the fixed end of the spring is connected with the casing, gaps exist between the first and second sides of the spring and the casing respectively, the first and second sides are provided with foil gauges respectively, the foil gauges are close to the fixed end of the spring, the position, corresponding to a free end, of the casing is provided with a first through hole whose internal diameter is larger than the bushing, the probe is connected with the free end, one end of the probe extends out of the casing via the first through hole, and the bushing sleeves the probe movably. The device is high in sealing performance, and long in service life. The system for measuring the internal displacement of concrete comprises the devices, and the devices are connected via conduits, and the system is high in precision. An installation method of the system comprises that a template supports the probe so that the probe has a certain precompressed amount, the bushing makes contact with the template, and bidirectional displacement can be measured.
Description
technical field [0001] The invention relates to the field of concrete internal displacement measurement, in particular to a device, system and installation method for measuring concrete internal displacement. Background technique [0002] On the high-speed rail ballastless track, the relative displacement between the limit boss at the bottom of the track slab and the surrounding structure will occur. Therefore, continuous observation of the service state of the ballastless track is required to provide measurement data for the evaluation of the state of the ballastless track, so as to improve the ballastless track. Ballast track maintenance and repair efficiency. [0003] At present, when using a displacement measuring device to measure the displacement occurring inside a concrete structure, it is difficult to replace other devices for measuring the internal displacement of the concrete after the concrete sets, so the measuring device is required to have a long life and not b...
