Description

Technical Field

[0001] This invention belongs to the field of soft soil reinforcement technology, specifically relating to a soft soil reinforcement device and method based on microwave reinforcement. Background Technology

[0002] The underlying layer is the foundation soil located below the bearing layer and within the compressibility layer or the depth that may be sheared. If its strength is lower and its compressibility is higher compared with the bearing layer, it is called a weak underlying layer. Its existence often threatens the safety of the superstructure. Therefore, it must be calculated for bearing capacity and settlement during the design. Appropriate methods should be used to reinforce the underlying layer. Existing microwave reinforcement equipment is difficult to process in zones according to the actual underlying layer structure and conditions. When the humidity and other conditions are uneven, it is difficult to achieve a relatively balanced and stable reinforcement effect. Summary of the Invention

[0006] A column is fixedly installed in the middle of the sleeve, and multiple movable bodies are movably installed on the column. At least one side of each movable body is meshed with a gear II. A push rod is movably installed on one side of each movable body. A push head is fixedly installed on one side of the push rod. A transmission shaft is fixed in the middle of the multiple gear IIs on one side and extends to the top of the column. A transmission assembly is connected to the outside of the column. The push rod and the movable body are elastically connected, and a pressure sensor is installed at the connection point. The multiple pressure sensors are electrically connected to multiple heating devices respectively.

[0007] Preferably, the transmission assembly includes a driven gear fixed to the top of the transmission shaft, and a motor is fixedly connected to the driven gear.

[0008] Preferably, the transmission assembly includes a driven gear fixed to the top of the transmission shaft, a timing belt is meshed with one side of the driven gear, and a motor is drivenly connected to the timing belt.

[0009] Preferably, a timing belt is fitted onto the output shaft of the motor, and a large gear is fitted onto one side of the timing belt and mounted on the central shaft of the large gear.

[0010] Preferably, a small gear is meshed with one side of the large gear, and a rotating shaft is connected to the bottom of the small gear through a one-way damping bearing. The rotating shaft is movably fixed to the inner wall of the sleeve through a fixed connection. The bottom of the rotating shaft is movably connected to a housing through a sealed bearing. The housing is fixedly connected to the inner wall of the sleeve through a connecting rod. A spiral blade is movably connected to the outer side of one end of the rotating shaft extending into the housing, and negative pressure is generated by the rotation of the spiral blade. Conveying pipes are provided at the top and bottom of the housing, with the bottom conveying pipe extending between the insulating layer and the metal sheet, and one end of the top conveying pipe extending to the outer side.

[0011] Preferably, the insulating layer is provided with multiple water-resistant elastic fabrics, and each of the multiple water-resistant elastic fabrics corresponds to a multiple pushing head.

[0012] Preferably, a second gear is fixed to one end of the drive shaft extending to one side of the moving body, and the second gear meshes with the moving body to drive the moving body to move.

[0013] Preferably, the transmission assembly includes a gear three that meshes with a rack, a long shaft that is fixedly connected to the middle of the gear three, the long shaft extending to the outside of the frame, a synchronous belt that is sleeved between multiple gear threes and moves synchronously with each other through the synchronous belt, and a motor two that is drivenly connected to one of the long shafts.

[0014] A reinforcement method for soft soil based on microwave reinforcement equipment, the specific steps of which are as follows:

[0015] S1. Move the frame to the appropriate position, and then start motor two to drive multiple gears three to rotate, which in turn drives the rack and the entire microwave reinforcement assembly to move up and down.

[0016] S2. After the microwave reinforcement component is inserted, the motor one is started to rotate intermittently in both forward and reverse directions, which drives the driven gear to rotate. Finally, the gear two rotates, causing the moving body to move back and forth. During the back and forth movement of the moving body, the push head is driven to continuously hit the water-proof elastic cloth, causing the water-proof elastic cloth to deform and push the corresponding metal sheet to expand outward. Then, based on the feedback from the pressure sensor inside the push rod at different positions, the working power of multiple heating devices is automatically adapted.

[0017] S3. When the motor rotates in both directions, the one-way damping bearing between the pinion and the shaft causes the shaft to rotate intermittently in one direction. During the rotation, the spiral blades rotate to generate negative pressure, and the liquid flowing between the insulating layer and the metal sheet is sucked out through the delivery pipe until it is discharged.

[0018] The technical effects and advantages of this invention are as follows: During the back-and-forth movement of the moving body, the push head continuously impacts the waterproof elastic cloth, causing deformation and pushing the corresponding metal sheet outwards. Then, based on feedback from the pressure sensors inside the push rods at different positions, the invention automatically adapts to the operating power of multiple heating devices. During the forward and reverse rotation of the motor, a one-way damping bearing between the pinion and the shaft causes the shaft to rotate intermittently in one direction. This rotation drives the spiral blades to generate negative pressure, which is then pumped out through the delivery pipe, drawing liquid between the insulating layer and the metal sheet. This process allows for targeted, zoned curing, with different curing powers for varying humidity levels at different depths, achieving overall uniform curing. Furthermore, the use of multiple metal sheets prevents interference between monitoring values ​​at different depths. The insulating layer ensures absolute isolation between the microwave-hardened component and the external environment. The waterproof elastic cloth prevents mutual elastic interference during monitoring. The entire process results in more uniform curing, higher efficiency, higher automation, and ease of use.

The insulating layer 107 provides absolute isolation between the microwave-hardened component 1 and the external environment. The use of the waterproof elastic cloth 106 prevents mutual elastic interference during monitoring due to the insulating layer 107. The entire process results in more uniform curing, higher efficiency, higher automation, and ease of use.
