The invention provides a digital geological logging system, which belongs to the technical field of geological logging, and comprises an early-stage geological management system, a data server system and a geological construction real-time logging system, and the early-stage geological management system and the geological construction real-time logging system are both connected with the data server system. The early-stage geological management system is used for inputting early-stage geological engineering information and carrying out early-stage management and planning on geological engineering, the geological construction real-time logging system is used for collecting, recognizing and logging geological construction site data, and the geological construction real-time logging system has offline recognition and logging caching functions. The data server system is used for storing and verifying geological information. Early-stage data of geological engineering are managed in real time and bound with later-stage construction engineering, data support is provided for later-stage construction, real-time datamation of the geological engineering is achieved, management is convenient, working efficiency is improved, and data errors are avoided.

This utility model belongs to the field of hole-opening tool technology, specifically relating to a hole opener, including a connecting rod and a central drill bit; characterized in that at least two centering rings are provided on the connecting part of the central drill bit, and the connecting rod is provided with a shaft hole to accommodate the connecting part of the central drill bit; the centering rings are inserted into the shaft hole with an interference fit, realizing the connection between the central drill bit and the connecting rod. This hole opener does not require the use of screws to tighten the central drill bit during installation, making installation and disassembly extremely convenient, and ensuring coaxiality to avoid damage to the central drill bit caused by wobbling.
