Before installing the ring ditch cover, it is essential to inspect the quality of the cover, particularly its strength class, to ensure it meets the design specifications. The cover should be free from cracks, chipped edges, honeycombing, pockmarks, and straight seams in the middle. A thorough visual inspection is recommended to avoid any potential issues that could compromise the integrity of the system. When it comes to installation, the top surface of the wall must be cleaned thoroughly and moistened before applying the mortar. Two key aspects need to be controlled: the elevation and the alignment of the drainage holes on the cover plates. Proper elevation ensures smooth drainage across the entire field, while aligned drainage holes contribute to the overall aesthetics. To maintain consistency, an elevation control line should be established during installation. Each cover plate must be laid flat, with uniform height and firm placement. After installing the first cover plate, a second one should be placed every 10 meters as a reference or direction control board. By using the central drainage hole of these two plates, a reference line can be pulled to guide the midline alignment. If misalignment occurs, adjustments must be made carefully without displacing the centerline. This process involves four continuous steps: placing, adjusting, aligning, and ensuring the centerline remains accurate. Any deviation outside the cover plate should be minimized, regardless of the workflow errors. The installation of the ring ditch primarily focuses on elevation and centerline alignment, both of which are crucial for the functionality and visual appeal of the site. Additionally, the installation must be stable, with tight joints and properly filled mortar. It’s important to clean the bottom of the trench before placing the cover plates to ensure a solid foundation. The following table outlines the quality requirements for the installation of prefabricated reinforced concrete covers: **Prefabricated Reinforced Concrete Cover Installation Quality Requirements** | Project | Allowable Deviation (mm) | Test Frequency | Testing Method | |--------|--------------------------|----------------|----------------| | | | Range | Points | | | Centerline Offset | ≤5 | 10m | 1 | A small amount of thread | | Height Difference Between Two Adjacent Boards | 3 | 10m | 1 | Using ruler | | Plate Bottom Wall Length | ±10 | 10m | 1 | Use ruler | | Sheet Seam Filling Mortar | Full | 10m | 1 | Observed | *Note: The strength grade of the prefabricated reinforced concrete cover plate must meet the design requirements. The appearance should be free from cracks, chipping, or other defects.* By following these guidelines, the installation will not only meet technical standards but also enhance the overall performance and appearance of the field. Attention to detail throughout the process is vital to ensure long-term durability and compliance with quality expectations.
