DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0036] The present invention proposes a method for rapid prototyping of landforms, such as Figure 1 As shown, the following steps are included:

[0037] Step 1: Analyze the frozen soil composition including soil, rock types and the relative proportions of soil, rock and water.

[0038] Step 2: According to the proportion of frozen soil components, crush limestone, basalt, granite, quartzite and other stones using a crusher to obtain rock particles of different specifications. Specifically, according to the characteristics of frozen soil, a jaw crusher is used to first crush large-size stones, and then a hammer crusher is used for secondary crushing to obtain small-size frozen soil raw materials.

[0039] Step 3: Mix the rocks, soil and water in a specific ratio using a mixer.

[0040] Step 4, determining the target frozen landform structure;

[0041] Determine the target permafrost structure. If the permafrost is flat, sloped or other permafrost, it can be regarded as a regular structure. If the permafrost is undulating or other irregular shapes, it can be regarded as an irregular structure.

[0042] Step 5, constructing frozen landforms;

[0043] When the frozen landform is a regular structure, a frozen landform unit is prepared by using a mold. Then, the frozen landform units are combined to obtain the target frozen landform. The mold includes a ramp mold and a cuboid mold. If the frozen landform is an irregular structure, the frozen soil raw material is surface modified by using an external modification tool, and then frozen in a low temperature environment. The external modification tool includes a shovel, a steel file, etc.

[0044] The inclined plane mold is composed of a first mold body, a first water injection port, a first water outlet and a mold support. The first mold body is a triangular prism structure, the top is not sealed, and the remaining surfaces are made of stainless steel materials to form an internal hollow cavity structure. The mold support support is connected to the first mold body. The first water injection port is located on the left side of the mold body and penetrates the internal cavity structure of the first mold body. The first water outlet is lower than the first water injection port, is located on the right side of the first mold body, and penetrates the internal cavity structure of the first mold body.

[0045] The rectangular parallelepiped mold is composed of a second mold body, a second water injection port, and a second water outlet. The rectangular parallelepiped mold body is a rectangular parallelepiped structure, the top is not sealed, and the remaining surfaces are made of stainless steel materials to form an internal hollow cavity structure. The second water injection port is located on the left side of the mold body and passes through the internal cavity structure of the second mold body. The second water outlet is lower than the second water injection port, is located on the right side of the second mold body, and passes through the internal cavity structure of the second mold body.

[0046] Example:

[0047] like Figure 1 As shown, the rapid prototyping process of frozen landforms in the present invention is as follows:

[0048] Step 1, frozen soil composition analysis;

[0049] By collecting frozen soil in the target area, we can comprehensively analyze the internal components of the frozen soil, including the rock and soil types and average particle size in the frozen soil, and the relative proportions of rock, soil and water.

[0050] Step 2, preparation of frozen soil raw materials;

[0051] The jaw crusher inputs rocks with a feed diameter of less than 220mm, outputs rock particles with a diameter of 10mm-50mm, and serves as the input of the hammer crusher. The hammer crusher then crushes the rock particles with a diameter of 0-3mm.

[0052] As preferred in this embodiment, after the diameter of the rock particles reaches 50 mm after the action of the jaw crusher, the hammer crusher is started to perform secondary crushing, and then the frozen soil raw materials are classified according to the rock type and rock particle size. By setting it in this way, the types of frozen soil raw materials are enriched and the material collection time is saved.

[0053] Step 3, stirring the frozen soil raw materials;

[0054] Prepare frozen soil raw materials according to the frozen soil component analysis results of step 1, stir the rock particles, soil and water through a mixer, and proceed to step 4 after the frozen soil raw materials are evenly mixed.

[0055] Step 4, determining whether the frozen landform is a regular structure;

[0056] If the frozen landform has a regular shape and can be expanded according to a single structural unit, it can be regarded as a regular structure. If the frozen landform does not have a regular shape and cannot be expanded according to a single structural unit, it can be regarded as an irregular structure.

[0057] Step 5, constructing frozen landforms;

[0058] If the target frozen landform has a regular structure, the frozen soil units can be prepared by molds first, and then the formed frozen soil units can be combined and spliced ​​to obtain the overall frozen soil landform.

[0059] Figure 2 The figure shows a bevel mold, which is made of stainless steel and has a triangular prism structure as a whole, and the top is not sealed. It consists of a first water inlet 1, a first water outlet 2, a first upper side plate 3, a first lower side plate 4, a mold support 5, a mold base 6, a first mold cavity 7, and a first molding area 8. Among them, the first water inlet 1 is set on the left side of the bevel mold, and the first drain 2 is set on the right side of the bevel mold. The first water inlet 1 is higher than the first water outlet 2. The first lower side template 4 is located above the mold support 5 and connected to the mold support 5, and the mold support 5 is connected to the base 6. The first upper side plate 3 is parallel to the first lower side plate 4 and has no contact, forming a hollow cavity structure 7. During use, the prepared frozen soil raw material is placed in the first molding area 8, and then the bevel mold is placed in a -10℃ environment and frozen for two hours. After the frozen soil raw material is fully condensed, the bevel mold is transferred to a room temperature environment. Hot water is injected from the first water inlet 1 to fill the first inner cavity 7 of the mold, and discharged from the first water outlet 2 for 5 minutes. This process accelerates the temperature rise of the first upper side plate 3 through the principle of heat conduction, thereby effectively promoting the rapid demoulding of the frozen soil structure in the first molding area 8. After the frozen soil structure is demoulded, the inclined surface mold is inverted to obtain Figure 4 The slope body frozen soil unit is shown.

[0060] Figure 3The rectangular mold is shown in the figure. The material is stainless steel, the whole is a rectangular structure, and the top is not sealed. It consists of a second water injection port 9, a second water outlet 13, a second upper side plate 10, a second lower side plate 11, a second mold cavity 12, and a second molding area 14. Among them, the second water injection port 9 is arranged on the left side of the bevel mold, the second drain port 13 is arranged on the right side of the bevel mold, and the second water injection port 9 is higher than the second water outlet 13. The second upper side plate 10 and the second lower side plate 11 constitute a hollow cavity structure. During use, the prepared frozen soil raw material is placed in the second molding area 14, and then the rectangular mold is placed in a -10℃ environment and frozen for two hours. After the frozen soil raw material is fully condensed, the bevel mold is transferred to a room temperature environment. Hot water is injected from the water injection port 9 to fill the mold cavity 11, and discharged from the water outlet 13 for 5 minutes. This process accelerates the temperature rise of the upper side plate 10 through the principle of heat conduction, thereby effectively promoting the rapid demoulding of the frozen soil structure in the molding area 14. After the frozen soil structure is demoulded, the inclined plane mold is inverted to obtain Figure 5 The rectangular frozen soil unit shown.

[0061] Will Figure 4 The slope frozen landform unit 15 shown is combined and spliced ​​to form Figure 6 The slope body frozen soil combination landform shown in Figure 17. Figure 5 The rectangular frozen landform units 16 shown are combined and spliced ​​to form Figure 6 The rectangular frozen soil combined landform 18 is shown. The combination of frozen soil landform units in the present invention is not limited to the above two. According to the test needs, frozen soil landform units of different thicknesses and inclinations can be prepared, and then the frozen soil landform units are spliced ​​and combined to form a target frozen soil environment.

[0062] If the permafrost landform is an irregular landform, the permafrost raw material in step 3 is externally modified to obtain a permafrost landform of a special shape, including an irregular permafrost pit, a permafrost mound, etc.
