Abstract
The utility model relates to the field of measuring tools, particularly to a survey mark for a metro rail basic control network. The survey mark for the metro rail basic control network is characterized in that the survey mark is composed of an embedded piece and an inserting rod. The embedded piece is fixedly connected with the inserting rod, and a measuring device is fixedly connected with the top end of the inserted rod. The survey mark for the metro rail basic control network has the advantages that the survey mark for the metro rail basic control network has a simple and reasonable structure; by embedding the embedded piece, measurement and acquisition of different data on measuring point can be quickly finished; and machining accuracy of each connecting piece is high, so data acquired from the measurement are high in accuracy. No matter how shallowly or deeply the embedded pieced is embedded, the embedded pieced does not destroy the structure of a rail transportation including a U-shaped beam on ground and segments under ground. When lower portions of a plane rod and an elevation rod are designed as a hexagonal structure, measuring error caused by rotation of a connecting rod in a field process can be effectively avoided.
