Permafrost has high strength and low permeability, but at the same time, it is extremely sensitive to temperature changes. Once disturbed by external heat, the ice in the permafrost will melt, causing the volume of the soil to change, and then causing a series of engineering geological problems such as foundation settlement and slope instability.

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0024] Refer to Figure 1 - Figure 4This utility model provides an embodiment of a support structure for a foundation pit in high-altitude permafrost, comprising a support frame 1, a connecting rod 3 fixedly connected to one side of the outer wall of a plug rod 2, a locking hole 11 inside the connecting rod 3, a locking groove 10 inside the support frame 1, and a snap-fit assembly inside the support frame 1 for conveniently splicing two support frames 1. The snap-fit assembly includes a round rod 9, one side of the outer wall of the round rod 9 fixedly connected to the inside of the support frame 1, and a snap-fit rod 5 slidably connected to the outer wall of the round rod 9. The snap-fit rod 5 has a sliding hole 12 inside. When a pushing member 7 is pulled inward, the pushing member 7 will cause the connecting ring 6 and the snap-fit rod 5 to slide along the outer wall of the round rod 9, and the spring 8 will be compressed. At this time, the snap-fit rod 5 will move out of the connecting groove 4, thereby making the connecting groove 4 unobstructed. The connecting ring 6 is fixedly connected to the outer wall of the snap-fit rod 5. A pusher 7 is fixedly connected to the outer wall of the connecting ring 6, and a spring 8 is sleeved on the outer wall of the round rod 9. A docking groove 4 is opened inside the support frame 1. The docking groove 4 is used to dock with the docking rod 3. After the pusher 7 is pulled to the locking groove 10, the pusher 7 is rotated so that the pusher 7 is locked into the locking groove 10. At this time, the locking rod 5 is kept away from the docking groove 4 to provide space for the insertion of the docking rod 3. Then, the docking rod 3 of the other support frame 1 is aligned with the docking groove 4 inside the support frame 1 and inserted until the docking rod 3 is fully inserted. The pusher 7 is pulled outward again to disengage it from the locking groove 10. At this time, under the restoring elastic force of the spring 8, the locking rod 5 will slide towards the docking groove 4 until the locking rod 5 can be fully inserted into the locking hole 11 inside the docking rod 3, thereby realizing the convenient splicing and fixing of the two support frames 1.
[0025] Reference Figure 1 and Figure 2 A rod 2 is fixedly connected to the lower surface of the support frame 1. When the support frame 1 is in use, the rod 2 is inserted into the permafrost of the plateau, which increases the contact area and friction with the permafrost, thereby improving the stability of the support frame 1 in the permafrost. A connecting plate 13 is fixedly connected to one side of the outer wall of the support frame 1, and a fixing rod 14 is fixedly connected to one side of the outer wall of the connecting plate 13. The combined use of the connecting plate 13 and the fixing rod 14 can further enhance the stability and reliability of the entire foundation pit support system. A connecting frame 15 and a support frame 16 are fixedly connected inside the support frame 1. The connection frame 15 and the support frame 16 are used to further enhance the stability and reliability of the entire foundation pit support system. Furthermore, aluminum alloy was chosen as the material for the connecting frame 15 and the support frame 16. While ensuring that the connecting frame 15 and the support frame 16 have sufficient strength, the weight of the entire support structure can be significantly reduced. In the permafrost region of the plateau, the lighter structural weight can reduce the pressure on the permafrost foundation, which is conducive to maintaining the stability of the permafrost. The surface of the support frame 1 is provided with a galvanized layer, which can resist the erosion of the permafrost meltwater, moisture in the air and other possible corrosive substances, significantly extending the service life of the support frame 1, thereby ensuring the overall stability of the support frame 1 and enabling it to better withstand the pressure of the soil around the foundation pit.
[0026] Working principle: when the support frame 1 needs to be spliced and assembled, first pull the push piece 7 inward, the connecting ring 6 and the clamping rod 5 will slide along the outer wall of the round rod 9 under the action of the push piece 7, and the spring 8 will be extruded and contracted, at this time the clamping rod 5 will move out from the inside of the butt joint groove 4, so that the butt joint groove 4 is in a smooth state, until the push piece 7 is pulled to the position of the locking groove 10, then rotate the push piece 7, make the push piece 7 clamped into the locking groove 10, at this time the clamping rod 5 remains away from the position of the butt joint groove 4, provide space for the insertion of the butt joint rod 3, then insert the butt joint rod 3 of another support frame 1 into the butt joint groove 4 inside the support frame 1, until the butt joint rod 3 is completely inserted into place, pull the push piece 7 outward again, so that it is separated from the locking groove 10, at this time the spring 8 is restored under the action of the elastic force, so that the clamping rod 5 slides to the direction of the butt joint groove 4, until the clamping rod 5 can be completely inserted into the clamping hole 11 inside the butt joint rod 3, so as to realize the convenient splicing and fixing of the two support frames 1;
[0027] When the support frame 1 is used, the insertion rod 2 is inserted into the plateau permafrost, which can increase the contact area and friction with the permafrost, improve the stability of the support frame 1 in the permafrost, and further enhance the stability and reliability of the whole foundation pit support system through the cooperation of the connecting disc 13 and the fixing rod 14, the surface of the support frame 1 is provided with a galvanized layer, which can resist the erosion of permafrost melting water, moisture in the air and other possible corrosive substances, significantly prolonging the service life of the support frame 1, through the setting of the connecting frame 15 and the supporting frame 16, and selecting aluminum alloy as the material for making the connecting frame 15 and the supporting frame 16, the strength of the connecting frame 15 and the supporting frame 16 is guaranteed, and the weight of the whole support structure is significantly reduced, in the plateau permafrost area, the lighter structure dead weight can reduce the pressure on the permafrost foundation, which is conducive to maintaining the stability of the permafrost, thereby ensuring the overall stability of the support frame 1, so that it can better withstand the pressure of the soil around the foundation pit.
