[0031] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0032] The embodiment of the present application discloses a device for sealing reserved holes in civil defense walls and panels.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 A device for blocking reserved openings of civil defense walls and panels includes baffles 1 arranged on both sides of the openings of the wall or panel for blocking the openings. The baffles 1 in this embodiment are 8 mm thick steel plates. A plurality of tension bolts 2 penetrating the wall or panel are installed between the two baffles 1. The plurality of tension bolts 2 are arranged around the center of the baffle 1. A filling material 3 is poured in the opening. The filling material 3 in this embodiment is micro-expansion concrete.

[0035] The implementation principle of Example 1 is: pouring filling material 3 into the hole, filling the hole with micro-expansive concrete, and the two baffles 1 have the effect of blocking the outflow of filling material 3 and protecting the hole. The baffles 1 are installed by tensioning bolts 2. The installation operation is simple. The filling material 3 cooperates with the baffles 1 to improve the sealing of the reserved holes in the civil defense walls and panels.

[0036] Example 2

[0037] Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that, in order to improve the sealing performance, a sealing ring 4 in the shape of a rectangular frame is provided on the side of the baffle 1 close to the hole. The sealing ring 4 is adapted to the size of the hole, and the cross-section of the sealing ring 4 is L-shaped. One side of the sealing ring 4 is bonded to the baffle 1, and the other side of the sealing ring 4 is placed on the side wall of the hole, so that the sealing performance is achieved through the sealing ring 4.

[0038] Reference Figure 3 and Figure 4A grouting hole 10 is provided on the baffle plate 1 near the top of the hole, and an inner sleeve 5 is fixedly connected to the position corresponding to the grouting hole 10. The length of the inner sleeve 5 is less than the length of the sealing ring 4 along the hole direction. The cross section of the inner sleeve 5 in this embodiment is semicircular, and the plane part of the semicircular inner sleeve 5 is located at its top. An outer sleeve 6 is detachably sleeved outside the inner sleeve 5. The shape of the outer sleeve 6 is the same as that of the inner sleeve 5, and the length of the outer sleeve 6 is greater than the length of the sealing ring 4 along the hole direction. A plugging cap 7 for plugging the grouting hole 10 is provided on the side of the baffle plate 1 away from the hole. The plugging cap 7 in this embodiment is threadedly connected to the grouting hole 10.

[0039] The implementation principle of Example 2 is as follows: the setting of the sealing ring 4 enhances the sealing of the connection between the baffle 1 and the hole. When the final stage of pouring is carried out, grouting can be injected into the hole through the grouting hole 10. The detachable design of the outer sleeve 6 and the inner sleeve 5 facilitates the disassembly of the baffle 1 in the later stage. At the same time, the design of the outer sleeve 6 can reduce the risk of slurry overflow. After the grouting is completed, the grouting hole 10 can be sealed by the sealing cap 7. Through the design of the above structure, not only the sealing performance of the hole is improved, but also the filling density of the filling material 3 is improved.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
