There are five basic requirements for the acceptance of the tunnel engineering. Combined with the characteristics of the shaft engineering, it can be summarized as:
   2. Complete the quality control information.
   3. The divisional engineering inspection data concerning the safety and main function of the roadway engineering should be reviewed and approved, which is the importance attached to the safety of the roadway engineering and the main function inspection. The inspection should first confirm that the information is complete and complete, and there should be no missing items; then the sample inspection report at the time of acceptance of the division project is reviewed, indicating that the implementation process of the sampling inspection is correct, the content is complete, and the qualified conclusion is reasonable.
   4. The main function should be qualified. The sampling test of the main function is the comprehensive inspection of the wellbore and roadway unit project, and it is also the most concerned content of the construction unit. Therefore, it is necessary to re-examine the important quality content of the unit project on the basis of the sub-item and the division project acceptance. . The sampling test is carried out on the basis of the inspection data file. The sampling test project is agreed upon by the participating parties, and the inspection site is determined by the sampling method of measurement and counting. All inspection results should meet the requirements of the design and specifications.
   5. Appreciation quality acceptance of the tunnel engineering. Generally, the quality of the roadway engineering is measured by visual inspection and observation, and the quality score is given by comprehensive evaluation. The quality of perception is generally judged by the subjective impression of the inspector, so the examination emphasizes comprehensive evaluation. For inspection points that do not meet the requirements, it is advisable to carry out remedial treatment through rework or other means.
