With the rapid development of the aviation industry, there is an increasing demand for safe apron operations and support capabilities. As a key facility in the apron fuel supply pipeline network, the performance and stability of the fuel hydrant well are crucial.
However, the traditional repair and replacement process for fuel hydrant wells faces challenges, including lengthy construction times and significant impacts on airport operations. To address these issues, this article proposes a prefabricated refueling hydrant well technology, aimed at achieving rapid replacement of hydrants under non-stop construction conditions. Through on-site experiments, we have verified the feasibility of this prefabricated fuel hydrant well technology, determined the minimum dismantling boundary, and studied the rapid dismantling process, prefabricated pavement structure and installation process, as well as the application of self-compacting and fast-setting high-strength wellbore filling materials. The experimental results demonstrate that this technology can complete all processes within 12 hours and 34 minutes, including cutting the pavement, breaking the pavement, dismantling the old fuel hydrant well, installing a new type of hydrant well, installing prefabricated pavement, grouting, and filling joints, etc., without affecting oil pressure. The grouting material and the strength of the prefabricated pavement meet the design requirements, and the grouting effect is satisfactory. The connection between the fuel hydrant well and the pavement meets the operational requirements. This study provides a new technical solution for the repair and replacement of fuel supply hydrant wells in civil airports, which is expected to significantly enhance the safety guarantee capability of fuel supply in civil airports.
