[0001] The utility model relates to a pre-buried support device, and more precisely to a pre-buried support device for suppressing the floating of segment linings. Background Art

[0002] After the installation of tunnel lining segments, gaps are likely to appear between the tunnel lining segments and the tunnel wall. After groundwater enters the gaps, it is easy to cause the tunnel lining segments to float. Therefore, we consider designing a device that can increase the pressure between the pre-buried rod segments and the tunnel wall after the installation of the pre-buried rod segments, thereby improving the stability of the segments and suppressing the floating of the segments. Summary of the Invention

[0003] The purpose of the utility model is to provide a pre-buried support device for suppressing the floating of segment linings, which can combine a pre-buried support for suppressing the floating of segment linings, a jacking device and a pre-buried steel plate device. After the pre-buried rod segments are installed into the tunnel wall, personnel can control the jacking device to jack the middle part of the pre-buried steel plate of the pre-buried steel plate device by rotating the jacking bolt, so that the middle part of the pre-buried steel plate protrudes towards the tunnel wall side, thereby further improving the matching force between the pre-buried rod segments and the tunnel wall, improving the stability of the pre-buried rod segments, and avoiding the floating of the pre-buried rod segments.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions:

One side of the pre-buried steel plate is attached to the outer side of the pre-buried rod segments. Strip-shaped through grooves are opened on both sides of the pre-buried steel plate, and sliding pre-buried components are installed in the strip-shaped through grooves. The sliding pre-buried components include pre-buried rods. One end of the pre-buried rod is pre-buried in the side wall of the pre-buried rod segments, the middle part of the pre-buried rod passes through the strip-shaped through groove, the pre-buried rod is a threaded rod, and the other end of the pre-buried rod is threadedly connected with a nut. The jacking component includes a pre-buried threaded pipe, the pre-buried threaded pipe is pre-buried in the side wall of the pre-buried rod segments, the pre-buried threaded pipe is threadedly connected with a jacking bolt, and the end of the screw rod of the jacking bolt can jack the middle part of the pre-buried steel plate.

[0006] To further achieve the purpose of the utility model, the following technical solution can also be adopted: Three or more pre-buried supports for suppressing the floating of segment linings can be installed on the pre-buried rod segments, and the three or more pre-buried supports for suppressing the floating of segment linings are evenly distributed on the side circumference of the pre-buried rod segments.

[0007] One end of the embedded rod is connected to several arc-shaped embedded rods, which are embedded in the side wall of the embedded rod segment. The direction of the arc of the arc-shaped embedded rod faces the center of the arc surface where the embedded rod segment is located.

[0008] Several reinforcing embedded ridges are connected to the side circumference of the embedded threaded pipe, and the reinforcing embedded ridges are embedded in the side wall of the embedded rod segment.

[0009] An embedded hole is opened on the embedded rod segment. The side circumference of the embedded threaded pipe is matched with the inner wall side circumference of the embedded hole. A space is provided on one side of the embedded hole close to the center of the arc where the embedded rod segment is located. The head of the pressing bolt can be immersed in the space, and the pressing bolt is an internal hexagonal bolt.

[0010] Arc-shaped surfaces are opened on both sides of the embedded steel plate, and the arc-shaped surfaces make the mating surfaces on both sides of the embedded steel plate and the embedded rod segment be arc-shaped surface structures.

[0011] The embedded rod can slide inside the strip-shaped through groove, and the nut cannot pass through the strip-shaped through groove.

[0012] Several square frame-shaped ridges are connected to the side of the embedded steel plate close to the hole wall.
