Geotechnical engineering investigation graph drawing and measuring device

The utility model provides a geotechnical engineering investigation graph drawing and measuring device. The geotechnical engineering investigation graph drawing and measuring device comprises a support, ground nails and a fixing plate. Ground nails are welded to the bottom of the support, and a fixing plate is welded to the middle of the support. A wire coil shaft is welded to the middle of the front side of the fixing plate, and the upper portion of the wire coil shaft is rotationally connected with a wire spool. An operation disc is fixed to the front end of the wire spool through a bolt, and a crank is arranged below the operation disc. The crank is fixed at the front end of the wire spool through a bolt; a steel ruler cable is wound around the upper portion of the wire spool, and the right end of the steel ruler cable is fixedly connected with a measuring head. Two guide mechanisms are arranged on the right side of the wire spool, and the guide mechanisms are arranged in an up-and-down symmetrical mode; t
