1. The plan layout of the measured wellbore shall indicate the center coordinates of the wellbore, the elevation of the wellhead, and the orientation of the crosshair. When there is a deviation from the design drawing, the cause shall be indicated; the longitudinal and cross-sectional views of the wellbore shall be measured.
2. Actual hydrological data and geological histogram of the wellbore.
3. Measurement record.
4. Sub-item, division project acceptance record, observation quality acceptance record, and spot check record of main function items.
5. Design change documents, concealed engineering acceptance records, engineering materials and test block test reports; records of major quality accidents.
6. Materials, specifications and other materials for supporting materials such as cement, steel bars, anchors, additives, and admixtures.
7. Wellbore equipment engineering related materials: design and construction drawings and measured completion drawings after installation; main raw material ex-factory certificate or material test report; concealed project acceptance record (beam buried manhole wall depth, beam and nest inner material, fill The concrete strength record of the plugging beam nest; the 11th record of the first layer of the canal beam.

1. Dimensions and deviations of the wellbore built. The existing concrete should not have dimensional deviations affecting the structural performance and the use function; if the part exceeding the allowable deviation is confirmed to be treated, the construction unit shall be responsible for the treatment, and the treatment part shall be re-accepted.
2. The contents of the filling material and filling quality of the block or concrete wall, and the quality of the bolt support.
3. Wall thickness and deviation of cast-in-place concrete shaft wall construction, concrete strength inspection. When the strength data of the concrete wall reserved test block is incomplete or has objection to the quality judgment, the wellbore drilling sampling or non-destructive inspection method (rebound detection) may be used for review, and the structural members shall be condensed according to relevant regulations. If the soil strength is not met, the safety of the completed structure shall be checked. If the minimum safety requirements and functional requirements are not met, the structural reinforcement shall be carried out according to the requirements.
4. The total leakage after completion of the wellbore shall comply with the requirements of the regulations, see Table lG420075.

5. Review of important quality data of wellbore equipment construction: installation of inner beam of the wellbore, installation of pipelines, installation of pipelines and deviations, concrete strength grade of bolting sockets, and anti-corrosion treatment of wellbore equipment materials.

        (3) Important observation quality content and inspection requirements during acceptance of the wellbore project

1. The surface quality inspection of the cast-in-place concrete shaft wall requires no obvious cracks. The serious defects such as honeycombs and holes within 1 m2 shall not exceed 2 places.
2. The exposed parts of the clamps, beams, water pipes, grouting pipes and other facilities buried during the construction of the borehole wall are removed; the abandoned orifices, beam sockets and temporary tung chambers to be abandoned have been panicked by concrete, and the main The concrete strength is not lower than the design strength of the well wall.
