The invention discloses an intelligent axial force instrument capable of being recycled, wherein the intelligent axial force instrument is used for measuring the axial force of a steel support. The intelligent axial force instrument comprises a support and an intelligent axial force instrument body installed on the support. The intelligent axial force instrument body is fixedly connected with the connection end of the steel support through the support. The intelligent axial force instrument body comprises a cylinder body, a vibration wire type axial force sensor arranged inside the cylinder body, a frequency reader and a data receiver, wherein the frequency reader protrudes out of the cylinder body and is embedded into the cylinder body. A data output line of the vibration wire type axial force sensor is connected with the frequency reader, and the frequency reader is connected with the data receiver in a wireless communication mode. The automatic data collecting and transmitting technology is adopted, the problem that due to the fact that a data cable is cut off, an axial meter is scraped or cannot measure the data is solved, meanwhile, the intelligent axial force instrument has the advantages of being convenient to mount and dismount, capable of being recycled and the like, and usage cost is reduced.
Description
technical field [0001] The invention relates to a test device in the technical field of construction engineering, in particular to a recyclable intelligent axial force meter for measuring the axial force of steel supports in deep foundation pit support engineering. Background technique [0002] In the deep foundation pit support structure engineering, steel support has become a commonly used method due to its advantages of small weight, convenient installation and disassembly, reusable, digging and support, pre-tightening force, and shortened construction period. Support form. At present, the device used to measure the axial force of steel supports in foundation pit monitoring is mainly an axial force meter. When installing the axial force meter, the axial force meter is often directly welded to the steel support structure. This installation method has the following defects: 1) The section of the axial force meter is much smaller than the steel support. When the axial force...
