In order to ensure the safety of underground structure construction and the surrounding environment of the foundation pit, the foundation pit needs to be supported, and the support anchor is one of the important components of the foundation pit support structure. During construction, after the support anchor is inserted into the side wall of the foundation pit, before tensioning and locking, it is necessary to apply a rated load to the support anchor on site, and use a displacement sensor to measure its displacement under load.
