The trenching shovel 4007 can be fixed to the drum tamping machine support frame 1109 by the trenching shovel fixing bolt 1112. When the drum tamping machine chain shaft driving motor 1106 fixed to the drum tamping machine chain shaft driving motor fixing seat 1107 rotates, the drum tamping machine chain shaft 4001 is driven to rotate in the drum tamping machine chain shaft supporting frame 1108, and then the drum tamping machine upper chain 4002 is driven to rotate, and the drum tamping machine lower chain 4003 is driven to rotate through the drum tamping machine chain transmission shaft 1110, thereby driving the drum tamping machine shaft 4004 to rotate in the bearing hole provided at the bottom end of the drum tamping machine support frame 1109, and then driving the drum tamping machine 4005 and the eccentric block 4006 of the drum tamping machine to rotate simultaneously, thereby realizing the rammed soil consolidation function. The upper end of the trenching shovel 4007 is provided with a plurality of screw holes, which can adjust the trenching depth and is fixed by the trenching shovel fixing bolts 1112 .

[0060] like Fig.11 As shown, the soil moisture detection structure 5000 is installed below the chassis structure 1000 and is located in front of the rotary tillage structure 2000. It is composed of a soil moisture rapid detector primary pneumatic push rod 5001, a soil moisture rapid detector secondary pneumatic push rod 5002 that is telescopic in the soil moisture rapid detector primary pneumatic push rod 5001, and a soil moisture rapid detector 5003. The soil moisture rapid detector primary pneumatic push rod 5001 can be fixed in the screw holes uniformly distributed on the pneumatic push rod fixing seat 1113 by bolts. The end of the soil moisture rapid detector secondary pneumatic push rod 5002 is connected to the soil moisture rapid detector 5003. The end of the soil moisture rapid detector 5003 is a hard metal probe. When the cylinder 1105 drives the soil moisture rapid detector secondary pneumatic push rod 5002 to extend, the hard metal probe at the end of the soil moisture rapid detector 5003 can be inserted into the soil to measure the soil moisture.

[0061] Specifically, when the soil moisture rapid detector 5003 detects soil moisture data, it can be converted into soil looseness and rammed earth consolidation strength through an algorithm.

[0062] The volumetric moisture content of the soil can be calculated using the following formula:

[0063]

[0064] In the formula, θ v is the soil volume moisture, V W is the soil water volume (m 3 ), V T is the total soil volume (m 3 ).

[0065] The tamping force is positively correlated with the soil volume humidity. The higher the soil volume humidity, the greater the tamping force needs to be. This can be obtained by the following formula:

[0066]

[0067] Where F is the tamping force (N), and K is a constant that is determined according to the specific soil type. For clay soil with a high water content, the K value is larger.

[0068] The looseness of the soil can be measured by its compaction, which can be calculated using the following formula:

[0069]

[0070] In the formula, ρ w is soil moisture (kg / m 3 ), M w is the total mass of wet soil (kg), V is the total volume of wet soil (m 3 ), ρ d is the actual dry density (kg / m 3 ), ρ max is the maximum dry density (kg / m 3 ), D is the compaction degree. Soil moisture is obtained by soil moisture rapid tester 5003, and the maximum dry density is obtained by compaction test results.

[0071] According to the above formula, the appropriate tamping force and soil looseness can be estimated according to the numerical value measured by the soil moisture rapid detector 5003, so as to achieve precise control of soil drainage and soil consolidation by adjusting the extension and retraction of the secondary pneumatic push rod 2008 and the rotation speed of the roller tamping chain shaft drive motor 1106.

[0072] The present invention provides a method for consolidating and draining rammed earth, using the above-mentioned consolidating and draining rammed earth device, comprising the following steps:

[0073] Before the device is operated, the soil moisture rapid detector secondary pneumatic push rod 5002 located in the soil moisture rapid detector primary pneumatic push rod 5001 can push the soil moisture rapid detector 5003 to be inserted into the soil to measure the soil moisture. Subsequently, according to the built-in algorithm and program, the compaction degree D and the tamping force F are obtained, and then converted into the soil penetration depth of the rotary tillage structure 2000, that is, the extension of the secondary pneumatic push rod 2008. The secondary pneumatic push rod 2008 finally pushes the rotary tillage structure 2000 to rotate into the soil, thereby achieving the soil loosening and drainage functions.

[0074] The discharged water flows into the drainage ditch opened by the trenching shovel 4007 fixed on the drum tamping support frame 1109. The loosened soil is initially ironed by the ironing structure 3000.

[0075] Then, the rotating drum tamping structure 4000 performs compaction, and the tamping force F can be converted into a speed signal of the drum tamping chain shaft driving motor 1106 through a program, thereby driving the rotation of the drum tamping structure 4000. Since the drum tamping 4005 has a drum tamping eccentric block 4006 inside, when the drum tamping 4005 rotates, the speed is proportional to the tamping force, thereby achieving tamping of different forces. Finally, the drainage, tamping and consolidation process of the cohesive soil or the soil with a large water content is achieved.

[0076] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be understood by anyone familiar with the technology within the technical scope disclosed by the present invention should be included in the scope of the present invention.
