The non-woven fabric containing dust, clay, and cement falls from between the fixed plate and the pressure plate into box section II. Activate motor section II, causing the rotating shaft section II to rotate on box section II, driving the blade section II to rotate. The blade section II then pulverizes the non-woven fabric containing dust, clay, and cement, producing arc-shaped blocks containing these components through the discharge port of box section II.

[0084] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0085] A method for preparing a carbonized foamed lightweight soil intermediate matrix for backfilling abutments, in the first embodiment of the present invention, comprises the following steps: 1) preparing a slurry from dust collector ash and clay; 2) injecting the slurry containing dust collector ash and clay into a housing section I81; 3) activating a motor section I84; 4) rotating a rotating shaft section I82 on the housing section I81, driving a blade section I83 to rotate, which in turn agitates the slurry containing dust collector ash and clay; 5) placing nonwoven fabric between a fixed plate section 31 and a pressure plate section 32; 6) rotating a clamping screw section 33 within a threaded hole in the fixed plate section 31, causing the flange of the clamping screw section 33 to act on the outer end face of the pressure plate section 32, thereby pressing the nonwoven fabric... The fabric is installed between the first clamping plate 3 and the second clamping plate 4, causing the swing telescopic cylinder 22 to be in a retracted state, causing the column 21 to swing on the ear seat 13, so that the column 21 is in a horizontal state. Through the telescopic movement of the displacement telescopic cylinder 6, the seat 11 is placed at the upper open part of the box part I81, causing the lifting telescopic cylinder 5 to be in an extended state, driving the first clamping plate 3 and the second clamping plate 4 to move downward, immersing the nonwoven fabric in a slurry containing dust and clay, allowing the dust and clay to enter the nonwoven fabric. After the nonwoven fabric has been immersed in the slurry containing dust and clay, the lifting telescopic cylinder 5 is in a retracted state, driving the first clamping plate 3 and the second clamping plate 4 upward. Move the seat 11 to the upper open end of the powder spraying box 9, extending the lifting and telescopic cylinder 5. Place the non-woven fabric containing dust and clay into the powder spraying box 9, and activate the conveying pump located on the cement storage tank. The powder nozzle of the powder spraying box 9 will spray cement onto the non-woven fabric containing dust and clay. After the cement spraying is completed, retract the lifting and telescopic cylinder 5. Then, place the seat 11 to the upper open end of the cooling box 91, extending the lifting and telescopic cylinder 5. Place the non-woven fabric containing dust, clay, and cement into the cooling box 91, and connect the cooling air nozzle of the cooling box 91 to the cooling air source. The nonwoven fabric containing dust, clay, and cement is initially cooled. After cooling for 1 to 2 minutes, the swinging telescopic cylinder 22 is extended, causing the column 21 to swing in the opposite direction on the ear seat 13, bringing the column 21 into a vertical position. The column 21 acts on the nonwoven fabric containing dust, clay, and cement, keeping it in a corrugated state. The temperature of the cooling box 91 is maintained at -85°C to -95°C to cool the nonwoven fabric containing dust, clay, and cement. After the cooling process is complete, the cold air nozzles and cold air source of the cooling box 91 are turned off.

[0086] With the lifting telescopic cylinder 5 in the retracted state, place the seat 11 on the upper open portion of the heating box 92, extending the lifting telescopic cylinder 5. Place the non-woven fabric containing dust, clay, and cement into the heating box 92, turning on the hot air nozzle and high-temperature argon source of the heating box 92 to begin heating the non-woven fabric. Maintain the temperature of the heating box 92 at 750℃ to 850℃ for the heating treatment of the non-woven fabric containing dust, clay, and cement. After the heating treatment of the non-woven fabric containing dust, clay, and cement is completed, turn off the hot air nozzle and high-temperature argon source of the heating box 92.

[0087] The lifting telescopic cylinder 5 is in the retracted state. The seat 11 is then placed on the upper open part of the box part II 931. The clamping screw part 33 rotates in the opposite direction of the threaded hole of the fixed plate part 31, causing the pressure plate part 32 to separate from the fixed plate part 31. The non-woven fabric containing dust, clay, and cement falls from between the fixed plate part 31 and the pressure plate part 32 into the box part II 931. The motor part II 934 is in the working state, and the rotating shaft part II 932 rotates on the box part II 931, driving the blade part II 933 to rotate. The blade part II 933 crushes the non-woven fabric containing dust, clay, and cement, and the resulting arc-shaped block containing dust, clay, and cement is obtained through the discharge port of the box part II 931.

[0088] One supporting example of the first embodiment of the present invention involves the following steps: A nonwoven fabric containing dust, clay, and cement is placed in a cooling box 91. The cooling air nozzles and the cooling air source of the cooling box 91 are turned on to begin cooling the nonwoven fabric. After cooling for one minute, the swinging telescopic cylinder 22 is extended, causing the column 21 to swing in the opposite direction on the ear seat 13, bringing the column 21 to a vertical position. The column 21 acts on the nonwoven fabric containing dust, clay, and cement, placing it in a corrugated state. The temperature of the cooling box 91 is maintained at -85°C to cool the nonwoven fabric. After the cooling process is complete, the cooling air nozzles and the cooling air source of the cooling box 91 are turned off.

[0089] With the lifting telescopic cylinder 5 in the retracted state, place the seat 11 on the upper open part of the heating box 92, and extend the lifting telescopic cylinder 5. Place the non-woven fabric containing dust, clay, and cement into the heating box 92, and turn on the hot air nozzle and high-temperature argon source of the heating box 92 to start heating the non-woven fabric containing dust, clay, and cement. Maintain the temperature of the heating box 92 at 750℃ to heat the non-woven fabric containing dust, clay, and cement. After the heating treatment of the non-woven fabric containing dust, clay, and cement is completed, turn off the hot air nozzle and high-temperature argon source of the heating box 92.

[0090] The second supporting example of the first embodiment of the present invention involves the following steps: A nonwoven fabric containing dust, clay, and cement is placed in a cooling box 91. The cooling air nozzles and the cooling air source of the cooling box 91 are turned on to begin cooling the nonwoven fabric. After cooling for 2 minutes, the swinging telescopic cylinder 22 is extended, causing the column 21 to swing in the opposite direction on the ear seat 13, bringing the column 21 to a vertical position. The column 21 acts on the nonwoven fabric containing dust, clay, and cement, placing it in a corrugated state. The temperature of the cooling box 91 is maintained at -95°C to cool the nonwoven fabric. After the cooling process is complete, the cooling air nozzles and the cooling air source of the cooling box 91 are turned off.

[0091] With the lifting telescopic cylinder 5 in the retracted state, place the seat 11 on the upper open part of the heating box 92, and extend the lifting telescopic cylinder 5. Place the non-woven fabric containing dust, clay, and cement into the heating box 92, and turn on the hot air nozzle and high-temperature argon source of the heating box 92 to start heating the non-woven fabric containing dust, clay, and cement. Maintain the temperature of the heating box 92 at 850℃ to heat the non-woven fabric containing dust, clay, and cement. After the heating treatment of the non-woven fabric containing dust, clay, and cement is completed, turn off the hot air nozzle and high-temperature argon source of the heating box 92.

[0092] The third supporting example of the first embodiment of the present invention involves the following steps: A nonwoven fabric containing dust, clay, and cement is placed in a cooling box 91. The cooling air nozzles and the cooling air source of the cooling box 91 are turned on to begin cooling the nonwoven fabric. After 1.5 minutes of cooling, the swinging telescopic cylinder 22 is extended, causing the column 21 to swing in the opposite direction on the ear seat 13, bringing the column 21 to a vertical position. The column 21 acts on the nonwoven fabric containing dust, clay, and cement, placing it in a corrugated state. The temperature of the cooling box 91 is maintained at -90°C to cool the nonwoven fabric. After the cooling process is complete, the cooling air nozzles and the cooling air source of the cooling box 91 are turned off.

[0093] With the lifting telescopic cylinder 5 in the retracted state, place the seat 11 on the upper open part of the heating box 92, and extend the lifting telescopic cylinder 5. Place the non-woven fabric containing dust, clay, and cement into the heating box 92, and turn on the hot air nozzle and high-temperature argon source of the heating box 92 to start heating the non-woven fabric containing dust, clay, and cement. Maintain the temperature of the heating box 92 at 800℃ to heat the non-woven fabric containing dust, clay, and cement. After the heating treatment of the non-woven fabric containing dust, clay, and cement is completed, turn off the hot air nozzle and high-temperature argon source of the heating box 92.

[0094] In verifying this invention, the inventors abandoned the existing technical features where the dispersed state of dust collector ash in foamed lightweight soil limited the effect of the foaming agent, thus affecting the foaming effect of the foamed lightweight soil. They first proposed an arc-shaped block feature to improve the distribution of dust collector ash in the foamed lightweight soil, resulting in the first unexpected technical effect: forming pores around the dust collector ash, allowing the foaming agent to enter and increasing the foaming effect; the second unexpected technical effect: pre-setting increased strength for the dust collector ash aggregate; the third unexpected technical effect: preventing environmental pollution during the production of foamed lightweight soil; and the fourth unexpected technical effect: increasing the use of blocky materials in the foamed lightweight soil raw materials, better meeting the foaming conditions of the foamed lightweight soil raw materials.

[0095] In the second embodiment of the present invention, the steps are as follows: the swing column 2, the first clamping plate 3 and the second clamping plate 4 realize the arc-shaped surface distribution of the non-woven fabric containing dust, clay and cement, and the soaking box 8, the powder spraying box 9, the cooling box 91 and the heating box 92 realize the carbonization treatment of the non-woven fabric containing dust, clay and cement.

[0096] The second embodiment of the present invention is based on the first embodiment.

[0097] This invention has the following characteristics:

[0098] 1. Due to the design of the arc-shaped block, the distribution of dust in the foamed lightweight soil is improved. This solves the technical problem that the foaming effect of the foamed lightweight soil is affected by the dispersed state of the dust and the limited effect of the foaming agent. Therefore, the foaming effect of the foamed lightweight soil and its use in backfilling are improved.

[0099] 2. Due to the design of support 1, swing column 2, first clamping plate 3, second clamping plate 4, lifting telescopic cylinder 5, displacement telescopic cylinder 6, support beam 7, soaking tank 8, powder spraying tank 9, cooling tank 91, heating tank 92 and crushing tank 93, the swing column 2, first clamping plate 3 and second clamping plate 4 realize the arc-shaped distribution of non-woven fabric containing dust, clay and cement, and the soaking tank 8, powder spraying tank 9, cooling tank 91 and heating tank 92 realize the carbonization treatment of non-woven fabric containing dust, clay and cement.

[0100] 3. Due to the design of non-woven fabric, it can bear dust, clay and cement.

[0101] 4. Because the design limits the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of this invention, and is not a technical feature obtained by formula calculation or a limited number of experiments. The experiment shows that the technical feature of the numerical range has achieved very good technical effect.

[0102] 5. Due to the design of the technical features of this invention, and the combined effect of the individual and collective technical features, experiments have shown that the performance indicators of this invention are at least 1.7 times that of existing performance indicators, and the invention has been evaluated to have good market value.

[0103] Other technical features that are the same as or similar to those of the arc-shaped blocks used to improve the distribution of dust in foamed lightweight soil are also embodiments of the present invention. Furthermore, the technical features of the embodiments described above can be combined in any way. In order to meet the requirements of the Patent Law, the Implementing Regulations of the Patent Law and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will no longer be described.

[0104] The above embodiments are merely one implementation of the carbonized foamed lightweight soil intermediate matrix, preparation device, and method for abutment backfilling provided by the present invention. Other modifications to the solution provided by the present invention, additions or reductions of components or steps, or application of the present invention to other technical fields similar to the present invention, all fall within the protection scope of the present invention.

Maintain the temperature of the heating box (92) at 750°C to 850°C to heat the nonwoven fabric containing dust, clay, and cement. After the heating treatment of the nonwoven fabric containing dust, clay, and cement is completed, turn off the hot air nozzle and high-temperature argon source of the heating box (92), and retract the lifting telescopic cylinder (5). Then place the seat (11) on the upper open part of the box part II (931) to press the pressure. The screw section (33) rotates in the opposite direction of the threaded hole in the fixed plate section (31), causing the pressure plate section (32) to separate from the fixed plate section (31). This allows the nonwoven fabric containing dust, clay, and cement to fall from between the fixed plate section (31) and the pressure plate section (32) into the box section II (931). This puts the motor section II (934) into operation, causing the rotating shaft section II (932) to rotate on the box section II (931), driving the blade section II (933) to rotate. The blade section II (933) then crushes the nonwoven fabric containing dust, clay, and cement, resulting in an arc-shaped block containing dust, clay, and cement through the discharge port of the box section II (931).

9. A carbonized foamed lightweight soil intermediate matrix for backfilling abutments according to claim 8, characterized in that: An arc-shaped block containing dust, clay, and cement, and carbonized.

10. The carbonized foam lightweight soil intermediate matrix according to claim 9, characterized by: By weight: it contains 70-82 parts dust, 10-24 parts clay, and 6-8 parts cement. Alternatively, the dust collector may be designated as industrial solid waste dust and the cement may be designated as 42.5 ordinary Portland cement.
