Description

Technical Field

[0001] This utility model belongs to the field of tunnel steel canopy construction technology, and provides a movable impact-resistant steel canopy that shortens the later maintenance construction time and reduces the later maintenance cost. Background Technology

[0002] To ensure the safety of tunnels located in high-altitude areas with year-round snow cover, corrugated steel sheet canopies are typically installed at tunnel entrances to prevent blockage during avalanches. Existing corrugated steel sheet canopies generally consist of support columns on a concrete foundation, corrugated steel sheets fixed to the support columns to form the canopy roof and walls, and the corrugated steel sheets are usually fixed to the support columns using structural steel.

[0003] When the aforementioned corrugated steel sheet tunnel structures are used in high-altitude areas with year-round snow cover, they are located in zones affected by modern glaciers. The surrounding glacial pressure causes the corrugated steel sheet tunnels to be compressed and damaged. Furthermore, due to the deep layer of heavy ice beneath the roadbed, long-term ice movement causes relative displacement between the corrugated steel sheet tunnel entrances and the tunnel openings, resulting in misalignment. Over time, this eventually leads to the loss of functionality of the corrugated steel sheet tunnels. This necessitates the dismantling of damaged or misaligned tunnel sections and the reinstallation of new ones, resulting in long maintenance times and high costs for the existing structures. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a movable impact-resistant steel shed that shortens the construction time for later maintenance and reduces the cost of later maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a movable impact-resistant steel tunnel, comprising: at least two longitudinally arranged steel tunnel segments, each steel tunnel segment including at least two longitudinally arranged tunnel support steel sections with the same transverse shape as the tunnel; multiple corrugated steel plates fixed on the tunnel support steel sections, the multiple corrugated steel plates integrally forming a corrugated steel plate layer; a corrugated steel plate roof is provided on the outer wall of the connection between two adjacent steel tunnel segments, and a foamed adhesive filling layer is filled between the corrugated steel plate roof and the corrugated steel plate layer;

[0008] The corrugated steel plate layer, the corrugated steel plate roof and the integral frame structure form an impact-resistant steel shed opening, and a buffer layer is provided on the outer wall of the impact-resistant steel shed opening;

[0009] When in use, the impact-resistant steel shed hole is fixed to the concrete of the area where it is used.

[0010] To ensure waterproofing, the above solution further includes: a geomembrane layer is provided on the outer wall of both the corrugated steel plate layer and the corrugated steel plate roof.

[0013] To ensure the stability of the waste tires on the impact-resistant steel tunnel and to facilitate the loading and unloading of the waste tires, the above solution further includes: the end of the anchor chain is fixed to the lifting ring by a shackle, the lifting ring at one end of the anchor chain is fixed to the web of the H-beam steel, and the lifting ring at the other end of the anchor chain is fixed to the tunnel.

[0014] To facilitate the loading and unloading of the shed support steel, the above solution further includes: the lower part of the shed support steel is fixed to an angle steel by bolts, and the bottom plate of the angle steel is welded to a transverse I-beam.
