TECHNICAL FIELD
[0001] The utility model relates to the technical field of airport runway pavement construction under non-stop flight, and particularly relates to an assembled airport runway pavement panel. BACKGROUND
[0002] In the field of non-stop flight construction of civil aviation airport, the construction of runway and taxiway is facing severe challenges. In view of the characteristics of concrete itself and a series of steps and procedures that must be followed in pavement construction, it is often difficult to fully meet the time arrangement. Concrete has specific time requirements in each link from mixing, pouring to maintenance during the construction process. Each procedure of pavement construction, such as base treatment, formwork installation, concrete paving, vibration compaction, finishing and light receiving, is crucial and requires a certain amount of time to ensure construction quality. However, under the restriction of non-stop flight construction, these time requirements often cannot be properly met, which can easily lead to a series of quality problems of pavement, such as insufficient strength, uneven surface, crack generation, etc., thereby posing a potential threat to the safe operation of the airport. When carrying out pavement paving and pavement maintenance work in the non-stop flight construction area of the airport, only the short time after the end of the flight can be used, which is generally about 2 hours.

[0024] The utility model will be further explained in detail in combination with the drawings, the described embodiment is only a part embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope of protection of the utility model.
[0025] As Figures 1 to 4 Indicated, the utility model discloses a prefabricated airport pavement panel, including rectangular concrete panel 1 and the embedded pipe that sets up in concrete panel 1, concrete panel 1 has four lateral faces, and each lateral face is provided with an embedded pipe respectively, and the embedded pipe of at least two adjacent lateral faces of concrete panel 1 inserts force bar 2, and the embedded pipe top part sets up grouting mouth 7, and the embedded pipe is used to push the force bar 2 in the inside thereof into another embedded pipe of adjacent concrete panel 1 by grouting to grouting mouth 7.
[0026] The airport pavement panel of the utility model includes two models, is A type and B type respectively, A type as Figure 1 And Figure 2 Indicated, is applicable to the new airport pavement construction, B type as Figure 3 And Figure 4 Indicated, is applicable to the airport pavement repair (change board).
[0027] The structure of A type and B type airport pavement panel is described below respectively:
[0028] As Figure 1 、 Figure 2 、 Figures 5 to 7 Indicated, the embedded pipe in the concrete panel of A type airport pavement panel divides into embedded grouting pipe 4 and embedded empty pipe 5, embedded grouting pipe 4 sets up in the adjacent two lateral faces of concrete panel 1, and the inside of embedded grouting pipe 4 is equipped with force bar 2, and embedded empty pipe 5 sets up in the other two lateral faces of concrete panel 1, and embedded grouting pipe 4 is used to push the force bar 2 in the inside thereof into another embedded empty pipe 5 of adjacent concrete panel by grouting to grouting mouth 7.
[0029] Embedded grouting pipe 4 includes grouting section and multiple installation sections, and grouting mouth 7 sets up in grouting section, and grouting section extends along the direction parallel to the lateral face of concrete panel, and multiple installation sections are vertically arranged along the extension direction of grouting section. Embedded empty pipe 5 includes connecting section and multiple socket sections, and connecting section extends along the direction parallel to the lateral face of concrete panel, and multiple connecting sections are vertically arranged along the extension direction of connecting section, and socket section is empty pipe, and is used to receive the force bar 2 from the installation section of embedded grouting pipe 4.
[0030] To ensure that the dowel bar 2 can be fully inserted into the concrete panel 1 before assembly, the length of the installation section is greater than or equal to the length of the dowel bar 2. To ensure that the dowel bars 2 are evenly distributed within the two adjacent airport pavement panels during assembly, the length of the installation section is twice the length of the socket section.
[0031] In order to enable the force transmission rod 2 to move smoothly, the diameter of the force transmission rod 2 is 2mm smaller than the inner diameter of each section of the pre-embedded pipe, that is, the diameter of the force transmission rod 2 is 2mm smaller than the inner diameter of the pre-embedded grouting pipe 4 and the pre-embedded empty pipe 5 respectively.
[0032] Furthermore, to ensure that the dowel bar 2 can move under the grouting pressure without grout seeping out from the gap between the dowel bar 2 and the embedded grouting pipe 4, an elastic rubber ring 3 is connected to the end of the dowel bar 2 facing away from the concrete panel 1. This elastic rubber ring 3 and the dowel bar 2 move as the grouting pressure inside the embedded grouting pipe 4 increases. The outer surface of the elastic rubber ring 3 is sealed to the inner surface of the embedded grouting pipe 4, preventing grout from seeping out from the gap between the dowel bar 2 and the embedded grouting pipe 4. The outer surface of the elastic rubber ring 3 is coated with lubricating oil, making its movement under grouting pressure smoother.
[0033] The grouting port 7 and the end of the socket section of the pre-embedded hollow pipe 5 are respectively provided with a wooden plug 6 that can be freely inserted and removed. The presence of the wooden plug 6 can prevent foreign objects from entering the grouting port 7 and the pre-embedded hollow pipe 5.
[0034] like Figure 3 and Figure 4 As shown, the difference between Type B and Type A airport pavement panels is that the four embedded pipes on the four sides of the concrete panel 1 are all embedded grouting pipes 4. This is because during airport pavement repair, the dowel bars inside the airport pavement panel around the replaced panel are removed due to the panel replacement, and the old airport pavement panel can no longer be grouted. Therefore, dowel bars 2 and embedded grouting pipes 4 are installed on all four sides of the concrete panel 1.
[0035] like Figure 8 As shown, during the construction of the new pavement, Type A prefabricated airport pavement panels are used. After the Type A prefabricated airport pavement panels are placed in the preset positions, grouting is performed into the grouting ports 7 on the surface of the concrete panel 1. The elastic rubber ring 3 is fixed relative to the dowel bar 2, and its outer surface is coated with lubricating oil to facilitate the sliding of the dowel bar 2 in the pre-embedded grouting pipe. Under the action of liquid pressure, the head of the dowel bar 2 is pushed into the socket section of the pre-embedded pipe 5. When the grouting pressure increases rapidly, and even when grout overflows from the grouting port 7, it indicates that the dowel bar 2 has been pushed into place.
[0036] The overall length of the force transmission rod 2 is 42 cm, and the overall length is in the pre-buried grouting pipe in the initial state. The receiving end of the pre-buried pipe 5 is 20 cm long, and after grouting is completed, the half of the force transmission rod 2 is pushed into the pre-buried pipe 5, the flat seam spacing is 2 cm, the pre-buried grouting pipe 4 and the pre-buried pipe 5 each contain 20 cm force transmission rod, that is, the assembly type airport pavement panel setting is completed.
[0037] As shown in Figure 9 When the pavement repair needs to be replaced, the B type assembly type airport pavement panel is used.
[0038] After cutting off the four edges of the damaged pavement panel to be replaced, the remaining half of the force transmission rod 2 remaining in the normally used pavement panel is taken out. The B type airport pavement panel is buried with a pre-buried grouting pipe 4 with a force transmission rod 2 around, the wooden plug 6 is taken out, and after positioning and leveling, grouting can be carried out, and the force transmission rod 2 around is pushed into the pre-buried grouting pipe 4 and the pre-buried pipe 5 of the four A type airport pavement panels. Because the grout hardens after the grouting construction when the new pavement is built, the pre-buried grouting pipe 4 can receive the force transmission rod with a length of 20 cm, and the pre-buried pipe 5, so the B type pavement panel can complete the reinstallation of the force transmission rod 2 around.
[0039] The above description of the disclosed embodiments can make the professional technical personnel in the art easily realize, and various modifications of the embodiments are obvious to the professional technical personnel in the art, and the general principle defined by the utility model can be realized in other embodiments without departing from the scope of the utility model. Therefore, the utility model is not limited to the embodiments shown in the text, but is consistent with the wider range of the disclosed principles and novel features.
