1) The initial positioning error of the bolt is primarily due to the sagging of the rope used during construction and measurement. 2) When pouring concrete, the main ribs connected to the structure are subjected to impact loads, causing them to sink and subsequently pull the bolts downward. To address this, strict construction measures must be implemented following the fundamental principle of early control. Careful adjustments should be made to the results of the control measurements to ensure precision.
The accuracy of the bolt positions is ensured through a series of well-controlled construction processes. Each stage must be executed with attention to detail and adherence to specifications.
During line laying, it is essential to maintain accuracy at every step. Baselines required for precise alignment must be established promptly. Additionally, to ensure accurate measurement of the layout lines, on-site surveying personnel must be properly trained in the correct use of instruments and steel rulers. Instruments should be calibrated regularly as per regulations, and steel rulers should be verified to guarantee reliable measurement results.
The steel bar project strictly controls the dimensions of the rebars to ensure that the binding forms are accurate. Experienced personnel should be assigned to oversee the processing, and regular or random sampling should be conducted. A clear reward and punishment system should be implemented to maintain high-quality standards in steelwork. To prevent the displacement of equipment bases, preventive measures must be taken, including crack-resistant techniques. In cast-in-place concrete structures, a "post-pouring strip" is often installed to reduce temperature stress and shrinkage deformation during construction, ensuring long-term structural integrity.
In summary, maintaining precision throughout the entire construction process requires careful planning, skilled execution, and continuous quality control. Every step, from initial setup to final inspection, plays a critical role in achieving the desired outcome. By adhering to best practices and ensuring that all personnel are properly trained, construction teams can significantly minimize errors and improve overall project quality.
