Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rapid treatment of thermal melt landslide disasters, and in particular to a rapid treatment structure for thermal melt landslide disasters and an implementation method thereof. Background Art
[0002] The permafrost on the Qinghai-Tibet Plateau is extremely sensitive to temperature changes. Under the influence of climate warming, the permafrost around the world has experienced a continuous degradation process in the past few decades. The melting of ground ice caused by the degradation of permafrost will induce a series of thermal thaw phenomena, which are mainly manifested as thermal thaw landslides in slope areas. Thermal thaw landslides refer to the exposure of ground ice caused by human activities or natural factors on slopes with thick layers of ground ice. During the melting season, the ground ice melts, and the upper thawed soil loses support and collapses under its own weight. The collapsed material covers the front edge of the landslide and the exposed ice layer on both sides. At the same time, new ground ice is exposed above, and it melts again to produce new collapses, and this process repeats. The development of thermal thaw landslides not only affects the water environment, ecological environment, and climate environment in cold regions, but also has a destructive effect on infrastructure construction. Therefore, it is of practical significance to carry out research on the rapid treatment technology of permafrost thermal thaw landslide disasters.
[0003] Thermal melt landslide disasters are characterized by rapid occurrence and long development duration. Especially without human intervention, the landslide range will gradually develop towards the top of the slope. At present, the treatment of thermal melt landslide disasters mainly draws on the experience of ordinary slope management projects, and builds gravity retaining walls and anti-slide piles at the front edge of thermal melt landslides to prevent the impact of thermal melt landslides on the front edge engineering structures. However, this method does not fundamentally block the continuous development of thermal melt landslides, especially the engineering facilities built at the rear edge of the landslide, which are potentially threatened by the continuous development of thermal melt landslides.
[0004] Therefore, there is an urgent need for a structure suitable for the rapid treatment of thermal thaw landslide disasters in permafrost areas, which can achieve rapid and low-cost treatment of thermal thaw landslides while ensuring the long-term stability of the disaster treatment point, thereby achieving the effect of treating both the symptoms and the root causes. Summary of the invention
[0005] The technical problem to be solved by the present invention is to provide a rapid treatment structure for thermal melt landslide disasters which is highly practical and simple in structure.
[0006] Another technical problem to be solved by the present invention is to provide an implementation method of the structure for rapidly treating thermal melt landslide disasters.
[0007] In order to solve the above problems, the present invention discloses a rapid treatment structure for thermal melt landslide disasters, which is characterized in that: the structure includes a sunshade structure, an anti-skid structure and a drainage ditch arranged along the moving direction of the landslide; the sunshade structure includes a sunshade cloth arranged on a sunshade cloth bracket; the sunshade cloth bracket is arranged at the rear edge of the thermal melt landslide; the anti-skid structure includes a micro anti-skid pile embedded with a recyclable thermal rod; the micro anti-skid pile is arranged below the sunshade structure at the rear edge of the thermal melt landslide, one end of which is driven into the mountain and the other end is exposed, and a thermal rod fixing clamp is provided at the exposed end; the recyclable thermal rod has a heat dissipation fin on the end exposed to the ground, and a thermal conductive coating is provided on the other end and embedded in the interior of the micro anti-skid pile; backfill soil is paved at the rear edge of the thermal melt landslide.
[0008] The sunshade cloth is provided with a sunshade cloth reserved hole; the sunshade cloth fixing buckles are provided at the node positions of the sunshade cloth bracket; the sunshade cloth is fixed and covered on the sunshade cloth bracket through the sunshade cloth reserved hole and the sunshade cloth fixing buckles.
[0009] The sunshade cloth is a light film material with a reflective coating, the outer contour of which matches the contour of the rear edge of the hot-melt slide, and a reserved hole for the sunshade cloth is provided at the edge.
[0010] The sunshade cloth bracket is made of square steel pipe, and its outer contour matches the sunshade cloth; the vertical legs of the sunshade cloth bracket are driven 50~80cm below the ground surface, and the gap between the upper edge and the natural ground surface is 30~50cm.
[0011] The number and positions of the reserved holes of the sunshade cloth are arranged correspondingly to the fixing buckles of the sunshade cloth.
[0012] The micro anti-slip pile is made of a round steel pipe with a length of 5 to 8 m and an inner diameter of 100 to 200 mm.
[0013] The outer diameter of the recyclable heat rod is 90-190 mm, and is slightly smaller than the inner diameter of the micro anti-slip pile.
[0014] The inner diameter of the hot rod fixing clamp is equal to the outer diameter of the recyclable hot rod.
[0015] The backfill soil is soil taken from the landslide material at the front edge of the thermal melt landslide or native meadow.
[0016] The implementation method of the thermal melt landslide disaster rapid treatment structure as described above comprises the following steps:
[0017] ⑴ After a thermal melt landslide disaster occurs, use a surveying drone to conduct aerial survey of the thermal melt landslide, and determine the size and shape of the sunshade structure, as well as the layout, quantity and depth of the anti-slip structure into the mountain through calculation; according to the aerial survey and calculation results, process the components of the sunshade structure and the anti-slip structure;
[0018] (2) According to the sliding direction, sliding amount, accumulation characteristics of the landslide and its impact on the engineering structure, determine the optimal drainage route and set up several drainage ditches along the optimal drainage route;
[0019] ⑶ Drive the processed micro anti-slip pile into the mountain at the set position, dig out the soil inside the micro anti-slip pile, and install a hot rod fixing clamp at the exposed end of the micro anti-slip pile;

[0022] (6) After the recyclable heat rod causes the underlying soil layer to freeze and stabilize in the cold season, remove the shade cloth and recycle the recyclable heat rod; at the same time, use machinery to collect the landslide materials at the front edge of the thermal melt landslide, and lay them as backfill soil at the rear edge of the thermal melt landslide, and then cover them with the shade cloth again.
[0023] Compared with the prior art, the present invention has the following advantages:
[0024] 1. In the present invention, setting a sunshade structure at the rear edge of the thermal melt landslide is a key step in achieving rapid disaster treatment. The sunshade structure prevents the exposed underground ice from absorbing heat from direct sunlight after the landslide occurs, promotes rapid cooling of the underground ice, slows down the melting rate of the underground ice, and alleviates the trend of further development of the thermal melt landslide.
[0025] 2. In the present invention, drainage ditches are arranged along the creeping direction of the landslide to timely discharge the underground ice melt water, thus laying a foundation for draining the landslide accumulated near the rear edge of the thermal melt landslide.
[0026] 3. The micro anti-slide piles arranged at the rear edge of the thermal melt landslide in the present invention prevent the further development of the disaster, ensure that the landslide will no longer affect the engineering structures at the front edge of the landslide, and at the same time provide a guarantee for the stability of the potential disaster-stricken structures at the rear edge of the thermal melt landslide.
[0027] 4. The recyclable heat rods embedded in the micro anti-slide piles of the present invention promote the refreezing of underground ice and shallow soil at the rear edge of thermal melt landslide in the cold season, avoiding the re-melting of underground ice in the warm season, thus ensuring the long-term stability of the disaster site.
[0028] 5. The present invention has a simple structure and strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The sunshade cloth bracket 32 is made of a square steel pipe, and its outer contour matches the sunshade cloth 31; the vertical legs of the sunshade cloth bracket 32 are driven 50-80 cm below the ground surface, and the gap between the upper edge and the natural ground surface is 30-50 cm.
[0042] The number and positions of the sunshade cloth reserved holes 33 are arranged correspondingly to the sunshade cloth fixing buckles 34 .
[0043] The micro anti-slip pile 41 is made of a round steel pipe with a length of 5 to 8 m and an inner diameter of 100 to 200 mm.
[0044] The outer diameter of the recyclable hot rod 42 is 90-190 mm, and is slightly smaller than the inner diameter of the micro anti-slip pile 41 .
[0045] The inner diameter of the hot rod fixing clamp 43 is equal to the outer diameter of the recyclable hot rod 42 .
[0046] The backfill soil 8 is soil or native meadow taken from the landslide material 2 at the front edge of the thermal melt landslide.
[0047] A method for implementing a rapid treatment structure for thermal melt landslide disasters, comprising the following steps:
[0048] (1) After the thermal melt landslide disaster occurs, use a surveying drone to conduct aerial survey of the thermal melt landslide, and determine the size and shape of the sunshade structure 3, as well as the layout position, quantity and depth of the anti-slip structure 4 into the mountain 1 through calculation; according to the aerial survey and calculation results, process the components of the sunshade structure 3 and the anti-slip structure 4;
[0049] (2) According to the sliding direction, sliding amount, accumulation characteristics of the landslide 2 and its impact on the engineering structure 6, determine the optimal drainage route, and set up several drainage ditches 5 along the optimal drainage route;
[0050] (3) Driving the processed micro anti-slip pile 41 into the mountain 1 at the set position, digging out the soil inside the micro anti-slip pile 41, and installing the hot rod fixing clamp 43 at the exposed end of the micro anti-slip pile 41;
[0051] (4) After the components of the sunshade structure 3 are transported to the site, the sunshade cloth bracket 32 is welded and assembled at the designed position, the sunshade cloth fixing buckle 34 is installed on the sunshade cloth bracket 32, and the sunshade cloth 31 is laid on the sunshade cloth bracket 32, and the sunshade cloth 31 is fixed on the sunshade cloth bracket 32 through the sunshade cloth reserved hole 33 and the sunshade cloth fixing buckle 34, so as to complete the rapid treatment of the thermal melt landslide disaster;
[0052] (5) When the thermal melt collapse tends to stop, a thermal conductive coating 44 is applied to one end of the recyclable hot rod 42, the recyclable hot rod 42 is embedded in the micro anti-slip pile 41, and the recyclable hot rod 42 is fixed by a hot rod fixing clamp 43;
[0053] (6) After the recyclable heat rod 42 causes the underlying soil layer to freeze and stabilize in the cold season, the sunshade cloth 31 is removed and the recyclable heat rod 42 is recovered; at the same time, the landslide material 2 at the front edge of the thermal melt landslide is collected by machinery and laid as backfill soil 8 at the rear edge of the thermal melt landslide, and the sunshade cloth 31 is covered again.
[0054] The working principle of the present invention is:
[0055] After the thermal melt landslide occurs, the drainage ditch 5 set along the sliding direction of the landslide 2 will promptly drain the melted water from the underground ice, thereby promoting the drainage and strength improvement of the landslide 2; secondly, the micro anti-slide piles 41 set at the rear edge of the landslide hinder the further development of the disaster and prevent the landslide 2 from continuing to affect the engineering structure 6; in addition, the sunshade structure 3 set at the rear edge of the landslide effectively blocks the exposed underground ice from direct sunlight, and the gap between the sunshade cloth 31 and the ground surface can provide natural wind convection heat exchange, thereby promoting the rapid cooling of the underground ice, slowing down the melting rate of the underground ice, and alleviating the further development of the thermal melt landslide.
[0056] After the thermal melt landslide stops developing in the cold season, embedding the recyclable heat rod 42 in the micro anti-slide pile 41 promotes the refreezing of underground ice and shallow soil at the rear edge of the thermal melt landslide, prevents the underground ice from melting again in the warm season, and ensures the long-term stability of the disaster site.
[0057] Figure 5 This is an actual photo of a thermal melt landslide on a certain railway before treatment. The incident occurred in June 2024. It can be seen from the figure (the photo was taken on July 10, 2024) that after the thermal melt landslide disaster occurred, the landslide 2 had a certain impact on the railway, especially causing bias pressure on the bridge piers. At the same time, the continued development of the thermal melt landslide posed a potential threat to the potential affected structure 7 located at the rear edge of the landslide.
[0058] Figures 6 and 7 It can be seen from the figure (taken on August 13, 2024) that by setting a drainage ditch in the direction of thermal melt landslide and setting a sunshade structure 3 at the rear edge, the continuous development of thermal melt landslide is prevented, and the impact of thermal melt landslide on the potential disaster-stricken structure 7 at the rear edge is avoided; especially from Figure 7 It can be seen that under the dual effects of the sunshade structure 3 and the drainage ditch 5, the landslide 2 is quickly drained and its strength is improved, thus preventing the landslide 2 from continuously affecting the railway.
