Embodiment Construction
[0018] The invention provides a pre-embedded device for monitoring the settlement between prefabricated bridge blocks. The pre-embedded device has a compact and reliable structure, can accurately predict different settlement conditions between prefabricated bridge blocks, and has the characteristics of convenient installation and simple use. .
[0019] like figure 1 As shown, this pre-embedded device for monitoring the settlement between prefabricated bridge blocks includes a metal sleeve; elastic deformation membrane chambers are installed at both ends of the metal sleeve (the elastic deformation membrane chambers installed at both ends preferably adopt the same structure form, they are placed in different adjacent bridge blocks during installation). Specifically, an elastic diaphragm is further provided in the elastic deformation membrane cavity, and the elastic diaphragm divides the inner space of the elastic deformation membrane cavity into a measurement chamber close to ...

The invention belongs to the technical field of prefabricated bridge block monitoring, and in particular relates to a pre-embedded device for monitoring settlement between prefabricated bridge blocks. The prefabricated device has a compact and reliable structure, can accurately predict different settlements between prefabricated bridge blocks, and has the characteristics of convenient installation and simple use. A pre-embedded device for monitoring settlement between prefabricated bridge blocks, comprising: a metal sleeve; two ends of the metal sleeve are respectively provided with elastic deformation membrane cavities; an elastic diaphragm is arranged in the elastic deformation membrane cavity, and the elastic membrane will elastically deform The inner space of the membrane cavity is divided into a measurement chamber close to the metal sleeve and a pressure-bearing chamber away from the metal sleeve. The optical fiber pressure measuring probe is fixedly installed in the measurement chamber; the pressure measurement sensing unit is installed inside the metal sleeve, and the pressure measurement sensing unit is installed. Communication connection with the fiber optic pressure measuring probe through optical fiber.
Description
technical field [0001] The invention belongs to the technical field of prefabricated bridge block monitoring, in particular to a pre-embedded device for monitoring settlement between prefabricated bridge blocks. Background technique [0002] Prefabricated bridge assembly construction technology is an emerging bridge construction technology. The main structure of the bridge mainly adopts the construction method of factory prefabrication and on-site assembly. The prefabricated structural parts in the prefabricated bridge are formed in the factory, which ensures the high quality and corrosion resistance of the prefabricated structural parts, and can ensure that the prefabricated structural parts have sufficient maintenance time. In addition, compared with traditional on-site construction bridges, prefabricated bridge assembly also has the characteristics of small on-site construction workload, short construction time, and high-quality construction of the entire bridge. It is w...
