What is the specific operation process when installing the ultra sleeve anchor

In construction projects, preparatory work before installation is the cornerstone of the entire construction process. Construction personnel need to conduct a comprehensive and detailed inspection of the Ultra Sleeve Anchor and its related accessories. This includes checking the anchor for defects such as rust and cracks, ensuring that the anchor plate is flat and has no deformation, and the anchor head is intact. At the same time, according to the actual project needs, accurately select the appropriate anchor specifications and models to ensure that its bearing capacity meets the design requirements. In addition, construction personnel need to be familiar with the construction drawings and technical requirements, clarify the specific location, direction and depth of the anchor, and conduct on-site surveys of the installation site to evaluate factors such as geological conditions and surrounding environment, so as to develop a scientific and reasonable construction plan.

The drilling process occupies a vital position in the entire installation process. According to the construction drawings, construction personnel need to use precise measuring tools to locate the hole position to ensure that the deviation of the hole position meets the requirements of relevant specifications. It is crucial to choose the right hole-making equipment for different geological conditions and anchoring requirements. When drilling in the soil layer, you can use a survey drill or an anchor bolter; when drilling in the rock layer, you should consider using a down-the-hole hammer drill. During the drilling process, the verticality of the drill rod must be checked at any time, and its inclination must be strictly controlled to be less than the specified value to prevent the anchor hole from being skewed. In addition, construction personnel must pay close attention to the size of the drill bit to ensure that the borehole diameter meets the design requirements to avoid the adverse effects of excessive or small borehole diameters on the installation and anchoring force of the anchor rod. After reaching the designed depth, a thorough hole cleaning operation should be carried out to ensure that the dust and debris in the hole are cleaned up. High-pressure air blowing or water flushing can be used to ensure that the anchor rod can be installed smoothly and exert the best anchoring performance.

The installation and fixing process of the anchor rod must be particularly rigorous. Place the treated anchor rod slowly and steadily into the drilled hole to avoid bending or twisting. During the installation process, it is necessary to ensure that the gap between the anchor rod and the hole wall is uniform to improve the anchoring effect. For anchor rods that need to be grouting fixed, the uniformity of the grouting volume and pressure must be ensured before grouting. Generally speaking, cement or cement mortar of appropriate grades is selected as the grouting material, and the water-cement ratio is controlled within a reasonable range. Grouting operations should be carried out continuously, and the grouting pipe should be pulled out while grouting, and the pulling height should not exceed the slurry surface in the hole to ensure the compactness of the grouting. During the grouting process, construction personnel need to closely observe the grouting situation. If the grouting volume is insufficient or leakage occurs, remedial measures should be taken in time.

Post-installation quality inspection is the last line of defense to ensure the safety and reliability of the anchoring system. Construction personnel should conduct quality inspections such as pull-out tests and torsion shear tests in accordance with relevant standards. The pull-out test applies tension to detect whether the pull-out force between the anchor rod and the surrounding soil or substrate meets the design requirements; while the torsion shear test is used to evaluate the shear resistance of the anchor rod. During the test, various data must be accurately recorded and scientifically analyzed. Only when all test indicators meet the design requirements can the installation of the anchoring system be confirmed to be qualified, thereby providing a guarantee for the safety of subsequent projects. Through the above series of rigorous steps and tests, the efficiency and safety of the anchoring system are ensured, laying a solid foundation for the smooth progress of the project.
