However, it should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well - known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0015] As Figure 1As shown in the figure, the utility model belongs to a double - box culvert single - aviation oil pipeline protection structure, which includes a bottom cushion layer 1, an aviation oil pipeline protection structure and an aviation oil pipeline support structure. The bottom cushion layer 1 is provided with the aviation oil pipeline protection structure, and the aviation oil pipeline support structure is arranged inside the aviation oil pipeline protection structure. The aviation oil pipeline support structure supports the aviation oil pipeline 6. The aviation oil pipeline protection structure includes a bottom plate 2, wall panels and a cover plate. The bottom plate 2 is arranged on the bottom cushion layer 1. Wall panels are arranged in parallel on both sides of the bottom plate 2, and a cover plate is arranged above the wall panels. The wall panels include an inner wall panel 32 and an outer wall panel 31. The outer wall panel 31 is arranged outside the inner wall panel 32. The aviation oil pipeline support structure is arranged between the inner wall panels 32. A support groove is arranged above the inner wall panel 32, and a support groove is arranged above the outer wall panel 31. The height of the outer wall panel 31 is greater than the height of the inner wall panel 32.
[0016] The bottom cushion layer 1 is a concrete layer, and the thickness of the concrete layer is not less than 100 mm.
[0017] The thickness of the bottom plate 2 is not less than 300 mm. A wall panel is arranged on one side of the bottom plate 2, and wall panels are symmetrically arranged on the other side of the bottom plate 2. The distance from the outer side of the wall panel to both sides of the bottom plate 2 is not less than 300 mm.
[0018] The outer wall panel 31 and the inner wall panel 32 are integrally formed. The inner wall of the outer wall panel 31 is connected to the outer wall of the inner wall panel 32. The sum of the widths of the outer wall panel 31 and the inner wall panel 32 is not less than 500 mm. During the construction of the bottom plate 2 and the wall panels, steel bars are first tied and formwork is set up, and then concrete is poured, so that the bottom plate 2 and the wall panels are integrally formed, increasing the support strength of the wall panels and the bottom plate 2, enabling vehicles to pass above the box culvert without affecting the entry and exit of ground vehicles and facilitating the layout of the pipeline of the aviation oil pipeline 6.
[0019] The cover plate includes a first cover plate 41 and a second cover plate 42. The first cover plate 41 is installed on the support groove of the outer wall panel 31, and the second cover plate 42 is installed on the support groove of the inner wall panel 32. The first cover plate 41 and the second cover plate 42 are arranged in parallel, and the distance between the first cover plate 41 and the second cover plate 42 is not greater than 100 mm.
[0020] The aviation oil pipeline support structure is a pipeline pier 5. The pipeline pier 5 is arranged in the middle of the bottom plate 2. The height of the pipeline pier 5 is 300 - 500 mm. The upper end surface of the pipeline pier 5 is an arc surface. The arc surface at the upper end of the pipeline pier 5 supports the side of the aviation oil pipeline 6. A rubber plate is arranged between the arc surface of the pipeline pier 5 and the aviation oil pipeline 6. The distance between the pipeline pier 5 and the two side inner wall panels 32 is not less than 500 mm. The pipeline pier 5 is arranged on the aviation oil pipeline 6 at intervals of 5 m.
[0021] After the bottom cushion layer 1 is constructed, steel bar binding and formwork support for the bottom slab 2 and the wall panels are carried out on the bottom cushion layer 1, and concrete is poured. The exterior wall panel 31 and the interior wall panel 32 are integrally bound and poured. Then, the construction of the pipeline support module is carried out to support the aviation fuel pipeline 6. After the support of the aviation fuel pipeline 6 is completed, the culvert is backfilled with yellow sand, and then the cover plate is installed to make the aviation fuel pipeline in a closed space, improving the protection of the aviation fuel pipeline. First, the second cover plate 42 is installed, and then the first cover plate 41 is installed;
[0022] After the cover plate installation of the double culvert is completed, the gaps between the cover plate and the support grooves of the two side wall panels are filled with stones to make the cover plate tightly fixed to the two side wall panels. Then, cement mortar is filled to prevent the cover plate from shifting due to the rolling of vehicles passing above the culvert, avoiding damage to the aviation fuel pipeline 6 and improving the protection effect of the culvert.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
