Prefabricated tunnel steel arch frame with monitoring equipment

The utility model belongs to the technical field of tunnel engineering, and particularly relates to a prefabricated tunnel steel arch frame with monitoring equipment. According to the utility model, an existing design arch frame is adopted; pre-integrated various monitoring devices, the stress and distribution characteristics of the primary support structure can be truly obtained, meanwhile, construction stagnation caused by field installation of various devices is avoided, the surrounding rock pressure borne by the section of the bottom layer lining structure, the radial internal force, the axial internal force and the steel arch internal force of the primary support structure can be systematically measured, and an accurate result is obtained. In addition, the requirements of different arch frames can be met by adjusting installation equipment, and the application range of the device is enlarged. 本实用新型属于隧道工程技术领域，尤其涉及一种带有监测设备的预制隧道钢拱架。本实用新型通过在一个既有设计拱架上，预先集成各类监测设备，可以在真实的得到初期支护结构受力大小及分布特征的同时，免去了现场安装各类设备导致的施工停滞并能
