Description

Technical Field

[0001] The invention relates to the technical field of microbial induced carbonate precipitation, and in particular to a self-repairing microbial induced carbonate precipitation slope reinforcement method and reinforcement device. Background Art

[0002] Microbial induced calcium carbonate precipitation is a biologically induced mineralization process, which includes urea decomposition, amino acid ammoniation, denitrification, reduction of dissimilatory sulfate bacteria, photosynthesis, methane oxidation and other metabolic processes. It is restricted by many influencing factors such as calcium source, temperature, pH conditions, ion concentration and so on, and shows great potential in the field of slope protection and reinforcement.

[0003] A Chinese invention patent with publication number CN117513242A discloses a river bank reinforcement device for water conservancy projects, including: a support frame for support, a reinforcement support assembly is arranged on the support frame, the reinforcement support assembly includes a limit leg arranged on the top of the support frame for support, and a first extension arm with adjustable angle is arranged on the top of the limit leg. The present invention adjusts the length of the extension leg on the limit leg through the corresponding coordinated use of various structures, thereby adjusting the force bearing area of ​​the bottom support of the limit leg, ensuring the stability of the subsequent reinforcement support assembly to reinforce the river embankment, so that the various structures on the first extension arm and the second extension arm are adjusted first, which makes it easy to lie on both sides of the river, and the column is traction-rotated by the extension of the output end of the third hydraulic rod to adjust the angle of the reinforcement support assembly, thereby improving the diversity of the device when in use.

[0004] In addition, since the device achieves reinforcement of river embankments through mechanical structures such as extended legs and hydraulic rods, it is difficult to repair itself when cracks or damage occurs in the slope protection. It is reinforced by increasing the grip between the river channel and the river channel by clamping the gripping plate and the limiting L rod into the embankments on both sides of the river channel, but it cannot fill the pores of soil particles and improve the soil density and strength. If it is exposed to water for a long time, it may rust and corrode, affecting the stability and service life of the device. In addition, the device is used to fix large-area river dams, and the overall fixing effect is poor, and it cannot be reinforced according to the local structure inside the river dam soil. Therefore, the river slope reinforcement device for water conservancy projects disclosed in Chinese invention patent CN117513242A cannot effectively improve the soil density and strength, and cannot ensure the stability of the slope protection structure itself.

Both ends of the spring 30313 are fixedly connected to the storage box 2 3037 and the fixed slot plate 30311, respectively.

[0051] It should be noted that: microbial dormant carriers are stored inside the storage box 3037. During the reciprocating sliding of the storage box 3037 inside the fixed groove plate 30311, the coverage area of ​​the microbial dormant carriers can be expanded according to the degree of soil rupture.

[0052] A self-repairing microbial-induced carbonate precipitation slope reinforcement method comprises the following steps:

[0053] Step 1: Insert the column 101 into the soil to complete the fixing of the device.

[0054] Step 2: The microbial dormant carrier induces the precipitation of carbonates in the soil, initially filling the gaps inside the soil and enhancing soil density.

[0055] Step 3: The memory alloy plate 2039 and the sensor controller 2038 continuously monitor the changes in the internal structure of the soil.

[0056] Step 4: The driving plate 3031 drives the second storage box 3037 to rotate, generating centrifugal force, so that the second storage box 3037 moves to the side away from the driving plate 3031, thereby expanding the spraying range.

[0057] Step 5: According to the looseness of the soil, the spraying frequency and range of nozzle 1 20310 and nozzle 2 3039 are automatically adjusted to ensure continuous reinforcement and repair of the soil.

[0058] The following is the working process and principle of the above embodiment:

[0059] The initial state is as follows: 20313 is in an uncompressed state, and the annular plate 2035 is at the bottom end of the slide groove 2031.

[0060] The working steps are as follows:

[0061] The operator presses down the top of the column 101, so that the column 101 is inserted into the soil, so that the column 101 drives the driving plate 3031 to move synchronously through the sliding groove 301, so that the driving plate 3031 drives the fixed groove plate 30311 to move synchronously close to the soil, so that the fixed groove plate 30311 contacts the slot 2034 to drive the fixed circular plate 1 2032 to move synchronously, so that the fixed circular plate 1 2032 drives the sensor controller 2038 to move to the side close to the soil, so that the sensor controller 2038 drives the memory alloy plate 2039 The synchronous movement enables the memory alloy plate 2039 to drive the nozzle 1 20310 to be inserted into the soil synchronously. At the same time, during the movement of the column 101, the bottom end of the annular plate 2035 contacts the soil, so that the annular plate 2035 slides from the inside of the chute 2033 to the inside of the chute 1 2031 under the action of the soil resistance, until the top end of the annular plate 2035 slides into the top end of the chute 1 2031, the column 101 and the memory alloy plate 2039 are completely inserted into the soil, so that the annular plate 2035 protects the internal equipment.

[0062] When the device is fixed inside the soil, the sensor controller 2038 controls the nozzle 1 20310 to fill the soil with the microbial dormant carrier, so that the microbial dormant carrier induces the precipitation of carbonates in the soil, and after the carbonates are precipitated, the gaps inside the soil are initially filled and fixed. Then the sensor controller 2038 controls the nozzle 2 3039 to start working, so that the nozzle 2 3039 sprays the microbial dormant carrier onto the surface of the soil through the nozzle 2 30310, so that the microbial dormant carrier penetrates into the soil, and induces the precipitation of carbonates inside the soil, thereby achieving the effect of reinforcing the soil surface.

[0063] When the soil is displaced under the action of external force, cracks appear in the soil, and the soil resists the memory alloy plate 2039 to deform, so that the sensor controller 2038 controls the speed of the driving plate 3031 rotating inside the slide groove 301 according to the deformation of the memory alloy plate 2039, so that the driving plate 3031 drives the annular plate 3032 and the annular connecting plate 3033 to rotate synchronously on the outer wall of the column 101, so that the annular plate 3032 drives the fixed groove plate 30311 to rotate synchronously, and the driving plate 3031 drives the fixed groove plate 30311 to rotate synchronously, so that the fixed groove plate 30311 and the guide groove 3035 rotate on the outside of the column 101 in a relatively static state, so that the fixed groove plate 30311 drives the storage box 2 3037 to rotate synchronously. During the rotation of the storage box 2 3037, the storage box 2 3037 is moved inside the fixed groove plate 30311 under the action of centrifugal force. Move to the side away from the driving plate 3031, so that the storage box 2 3037 moves on the outer wall of the sliding rod 2 30312 to the side away from the driving plate 3031, and the storage box 2 3037 squeezes the spring 30313, and at the same time, the storage box 2 3037 drives the guide tube 2 3038 to move synchronously, so that the guide tube 2 3038 drives the nozzle 2 3039 and the nozzle 2 30310 to move synchronously, thereby expanding the area after the nozzle 2 30310 sprays, and the deformation amount of the memory alloy plate 2039 reflects the looseness of the internal structure of the soil, so that the sensor controller 2038 controls the nozzle 1 20310 and the nozzle 2 3039 to spray the microbial dormant carrier into and on the surface of the loose soil, so that the microbial dormant carrier induces the precipitation of carbonate, and then the precipitated carbonate particles enter the inside of the soil cracks, thereby improving the soil density and strength, and thus reinforcing the slope protection. The deformation of the memory alloy plate 2039 reflects the looseness of the internal structure of the soil, so that the sensor controller 2038 controls the rotation speed of the driving plate 3031, so that the driving plate 3031 drives the storage box 2 3037 to rotate through the fixed slot plate 30311 to generate different centrifugal forces, so that the storage box 2 3037 drives the nozzle 2 3039 to move to the side farther from the driving plate 3031 for spraying, thereby expanding the spraying range of the nozzle 2 3039, and thus being able to effectively fix the soil in a large range. The memory alloy plate 2039 and the sensor controller 2038 detect the changes in the internal structure of the soil in real time, so that the device can automatically repair the internal structure of the soil in a timely manner, thereby improving the flexibility of the device.
