Abstract
Description
Technical Field
[0001] The utility model relates to an energy dissipation structure, in particular to an ice-breaking deceleration energy dissipation structure, belonging to the technical field of glacier protection facilities. Background Art
[0002] A glacier is a natural ice body that has existed on the surface of the polar region or high mountains for many years and has a state of moving along the ground. Glaciers are formed from snow that has accumulated over the years through processes such as compaction, recrystallization, and refreezing. Under the action of gravity, ice slowly flows down the mountain slope. During the flowing process, it gradually solidifies and finally forms a glacier. When the density of névé reaches 0.5 - 0.6 g / cm³, the process of névé formation becomes slow. Under the action of its own weight, the névé further compacts or is infiltrated by meltwater and refrozen, and the crystal grains change their size and shape, showing directional growth. When its density reaches 0.84 g / cm³, the crystal grains lose air permeability and water permeability and become glacier ice.
[0003] Moving glaciers bring great disasters to human life. People often feel helpless in the face of moving glaciers. The damage caused by glacier movement to roads and villages is huge. While many scientific communities are studying glaciers, they have not considered how to eliminate the harm caused by glacier activities to humans.
[0004] Therefore, the present invention considers taking certain measures to set up an energy dissipation and deceleration method in front of roads and villages during glacier activities, so that the glacier stops moving within a certain range or breaks into small pieces, thereby reducing or eliminating the destructive force of the glacier and achieving the protection or weakening of the damage to roads and villages. Content of the Utility Model
[0005] The purpose of the utility model is to solve the above-mentioned disadvantages and provide an ice-breaking deceleration energy dissipation structure, which breaks up the moving glacier, reduces the moving range of the broken blocks, buffers the impact of glacier movement, and reduces the destructive force of the glacier.
[0006] The technical solution adopted by the utility model to achieve the above purpose is as follows
[0007] An ice-breaking deceleration energy dissipation structure includes a number of ice-breaking cones horizontally distributed in the direction of glacier movement downward; each of the ice-breaking cones is coated with a protective layer; the protective layer is connected to the ice-breaking cone through a connecting piece; each of the ice-breaking cones is fixed to the ground through an anchor pile; a buffer energy dissipation member is arranged between each of the ice-breaking cones.
[0008] Furthermore, each of the ice-breaking cones includes a reinforced concrete block; the protective layer is a steel plate; the thickness of the steel plate is 5 cm; the connecting piece is a steel bar, a steel strand or a plug rod; the connecting piece penetrates through the steel plate and is inserted into the reinforced concrete block.
[0009] Further, the reinforced concrete block includes a base and a conical end; the conical end is arranged on one side of the base close to the direction of glacier movement; the anchor piles are arranged on both sides of the conical end; the inner contour of the protective layer is consistent with the outer contour of the conical end.
[0010] Further, the buffer energy dissipation member includes a support column arranged between any two ice-breaking cones; the support column is an I-beam; columns are arranged on the outer side of the protective layer.
[0011] Further, the buffer energy dissipation member further includes an energy dissipation rope connected between two columns adjacent to the ice-breaking cones; a load-relieving ring is arranged on the energy dissipation rope.
[0012] Further, the lower end of the support column is inserted into the ground; the upper end of the support column is connected to the energy dissipation rope; the energy dissipation rope is a steel strand or a steel wire rope.
[0013] The utility model has the following beneficial effects: By arranging ice-breaking cones in the direction of glacier movement, the outer surface of the ice-breaking cone body is wrapped with a protective layer, and a reinforced concrete masonry is arranged in the middle to support the protective layer. The steel plate is fixed on the reinforced concrete masonry with steel bars or steel strands (connecting rods) and is buried in the ground not less than 1m as a whole. The reinforced concrete masonry is anchored to the ground with reinforced concrete piles and does not move under the action of the moving glacier, so as to play an ice-breaking role. A buffer energy dissipation member is arranged between the ice-breaking cones, so that the broken glacier stays or weakens the downward movement speed through the support piles and the pulling ropes, achieving the effect of energy dissipation and speed reduction.

[0019] See Figure 1 - Figure 2 ,
[0020] An ice-breaking, decelerating and energy-dissipating structure includes a number of ice-breaking cones horizontally distributed in the direction of glacier movement downward; a protective layer 1 is wrapped around each of the ice-breaking cones; the protective layer 1 is connected to the ice-breaking cone through a connecting member 4; each of the ice-breaking cones is fixed to the ground by an anchoring pile 2; a buffer energy-dissipating member is arranged between each of the ice-breaking cones.
[0021] Furthermore, each of the ice-breaking cones includes a reinforced concrete block 3; the protective layer 1 is a steel plate; the thickness of the steel plate is 5 cm; the connecting member 4 is a steel bar, a steel strand or a plug rod; the connecting member 4 penetrates through the steel plate and is inserted into the reinforced concrete block 3.
[0022] Furthermore, the reinforced concrete block 3 includes a base and a conical end; the conical end is arranged on one side of the base close to the direction of glacier movement downward; the anchoring piles 2 are arranged on both sides of the conical end; the inner contour of the protective layer 1 is consistent with the outer contour of the conical end.
[0023] Furthermore, the buffer energy-dissipating member includes a support column 5 arranged between any two ice-breaking cones; the support column 5 is an I-beam; a pull ring 6 is arranged on the outer side of the protective layer 1.
[0024] Furthermore, the buffer energy-dissipating member further includes an energy-dissipating rope 7 connected between two pull rings 6 of adjacent ice-breaking cones; a load-relieving ring 8 is arranged on the energy-dissipating rope 7.
[0025] Furthermore, the lower end of the support column 5 is inserted into the ground; the upper end of the support column 5 is connected to the energy-dissipating rope 7; the energy-dissipating rope 7 is a steel strand or a steel wire rope.
[0026] Working principle: The basic body of the ice-breaking and energy-dissipating system consists of an ice-breaking cone, a protective layer 1 and an anchor pile 2, which play the role of ice-breaking; the energy-dissipating rope 7, the unloading ring 8 and the support column 5 play the role of energy dissipation and deceleration. The spacing of the ice-breaking cones is set according to the downward movement speed of the ice mass. Generally, a spacing of 10 - 50 m is appropriate. Its height is determined by the thickness of the ice mass. When the thickness is large, the ice-breaking cone is higher. When it is thin, it can be set lower. Generally, when the thickness is between 1 - 3 m, the ice mass can be broken. Although the main ice mass has high stiffness, its brittleness is extremely weak. In general, the ice mass can be broken. The setting range of the ice-breaking cones should cover the downward movement range of the ice mass and extend about 30 m at both ends to avoid omission. Generally, 1 - 3 layers of energy-dissipating ropes are set, 1 - 2 layers when the ice mass is thin, and 3 layers when it is thick. The spacing can be 1 - 3 m. 1 - 3 support columns are set to prevent the ice mass from slipping out and causing harm.
