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.
