[0011] The present invention provides a frozen soil subgrade structure and its construction equipment based on the thermal-mechanical coupling effect, and has the following beneficial effects:

[0012] 1. For the frozen soil subgrade structure and its construction equipment based on the thermal-mechanical coupling effect, by providing heat pipes and light-colored coatings, through the combination of heat pipes and light-colored coatings, the temperature rise can be prevented from causing the foundation to melt. Through the heat pipes, heat can only be transferred from the lower end of the ground to the upper end of the ground and cannot conduct heat in the reverse direction, which can effectively reduce the underground temperature of the frozen soil.

[0013] 2. For the frozen soil subgrade structure and its construction equipment based on the thermal-mechanical coupling effect, by providing bucket teeth and a top plate, during excavation construction, the bucket that can only be used for excavation can be deformed, and the bucket teeth can be lengthened, so that the bucket teeth can be used for frozen soil loosening work. By continuously impacting downward when the top plate and the bucket teeth are inserted into the soil, the top plate and the bucket teeth can be inserted into the soil for loosening work. When excavation is required, the top plate and the bucket teeth can be reset, and excavation work can be carried out by using the bucket teeth, the bucket and the bucket cavity.

[0014] 3. The frozen soil subgrade structure and its construction equipment based on the thermal-mechanical coupling effect are provided with an installation box and an ejection bladder. When the bucket teeth and the top plate are obliquely inserted into the soil, the ejection bladder can be inflated, and the soil on the surface of the top plate can be loosened by the ejection bladder, avoiding the deformation and fracture of the top plate when the top plate ejects the soil block.

[0015] 4. The frozen soil subgrade structure and its construction equipment based on the thermal-mechanical coupling effect are provided with a winding roller, a worm gear and a traction belt. During the process of inserting the top plate and the bucket teeth into the soil, the ejection bladder is wound around the outside of a winding roller, thereby preventing the friction suffered by the ejection bladder during insertion and wearing out the ejection bladder. Then, after inserting into the soil, the ejection bladder is released, and the soil loosening work is carried out through the inflation of the ejection bladder. Description of the Drawings

[0037] Wherein, one side of the support arm 2 is fixedly connected with a liquid tank 39. The surface of the liquid tank 39 is fixedly connected with a first liquid pump 40.

Then, the oil liquid inside the scraping liquid sac 38 is pumped out through the seventh elastic tube 37, and then the oil liquid inside the seventh elastic tube 37 is pumped out and discharged into the liquid tank 39 through the seventh elastic tube 37, the three-way joint 45 and the third liquid pump 42 for collection and storage, so that the scraping liquid sac 38 contracts and returns to its original position.

[0038] In summary, for the frozen soil subgrade structure and its construction equipment based on the thermal-mechanical coupling effect, when excavation is required during use, due to the hard frozen soil geology, which causes inconvenience in excavation, the oil liquid inside the liquid tank 39 can be pumped out by the first liquid pump 40 and discharged into the first elastic tube 11, and enter the second liquid sac 10 through the first elastic tube 11, so that the second liquid sac 10 expands. The oil liquid inside the fifth elastic tube 33 and the first liquid sac 9 is pumped out by the second liquid pump 41, and then the sucked oil liquid is discharged into the liquid tank 39 by the second liquid pump 41, so that the first liquid sac 9 contracts. At this time, the moving block 6 pushes the top plate 7 and the bucket teeth 8 to extend, and the extended bucket teeth 8 are used to loosen the ground. When inserting into the ground, the bucket teeth 8 can be driven to expand and contract by continuously driving the top plate 7, and hydraulic impact is applied to the ground, so that the bucket teeth 8 can be inserted into the soil. After being inserted into the soil;

[0039] Then, the oil in the liquid tank 39 is sucked in by the fifth liquid pump 44, and then the oil is discharged into the fourth elastic tube 30 through one end of the fifth liquid pump 44, and is discharged into the fourth liquid sac 29 through the fourth elastic tube 30, causing the fourth liquid sac 29 to expand. The oil in the third elastic tube 26 and the third liquid sac 25 is sucked out by the fourth liquid pump 43, causing the third liquid sac 25 to contract. At this time, the push block 27 drives the rack 28 to move into the driving cavity 24, so that the rack 28 drives the drive gear 23 to drive the rotating shaft 21 to drive the bevel gear 22 and the transmission rod 17 to rotate through the drive gear 23. The transmission rod 17 drives the two winding rollers 13 to rotate in the opposite direction through the two worm segments 18 and the worm wheel 14, so that one winding roller 13 releases the traction belt 15, and the other winding roller 13 winds up the traction belt 15, causing the ejecting liquid sac 16 to move to the surface of the mounting box 12. Then, the fourth liquid pump 43 discharges the oil in the liquid tank 39 into the three-way joint 45, enters the sixth elastic tube 36 through the opened switch valve, so that the oil in the sixth elastic tube 36 enters the hose 35 through the rotary joint 34, and then enters the ejecting liquid sac 16 through the hose 35, causing the ejecting liquid sac 16 to expand, lifting the soil above the top plate 7, thereby loosening the frozen soil of the road surface. Then, the fourth liquid pump 43 sucks out the oil in the sixth elastic tube 36, the rotary joint 34, the hose 35 and the ejecting liquid sac 16, then sucks it into the fourth liquid pump 43 through the three-way joint 45, and then discharges the oil into the liquid tank 39 for storage through the other end of the fourth liquid pump 43, causing the ejecting liquid sac 16 to contract. Then, the fourth liquid pump 43 sucks the oil in the liquid tank 39, and then discharges the oil into the third elastic tube 26 through the fourth liquid pump 43, enters the third liquid sac 25 through the third elastic tube 26, causing the third liquid sac 25 to expand. The oil in the fourth elastic tube 30 and the fourth liquid sac 29 is sucked out by the fifth liquid pump 44, causing the fourth liquid sac 29 to contract. At this time, the push block 27 moves the rack 28 upward, enters the mounting box 12 through the driving groove 20, so that the rack 28 drives the drive gear 23 to drive the rotating shaft 21, the bevel gear 22, the transmission rod 17, the worm segment 18, the worm wheel 14 and the winding roller 13 to rotate back to their original positions, so that one winding roller 13 winds up the traction belt 15, and the other winding roller 13 releases the traction belt 15, winding the ejecting liquid sac 16 on the outside of one winding roller 13, so that one traction belt 15 is located outside the mounting box 12;

[0040] When the top plate 7 needs to be stored, the second liquid pump 41 pumps out the hydraulic oil inside the liquid tank 39, then discharges it into the fifth elastic tube 33, and then enters the first liquid sac 9 through the fifth elastic tube 33, causing the first liquid sac 9 to expand. The first liquid pump 40 pumps out the hydraulic oil inside the moving block 6, and then discharges the hydraulic oil into the liquid tank 39 through the other end of the first liquid pump 40 for storage, causing the second liquid sac 10 to contract, causing the moving block 6 to drive the top plate 7 and the bucket teeth 8 into the bucket 3, and causing the top plate 7 and the bucket teeth 8 to be retracted.
