Description

Technical Field

[0001] The present invention relates to the technical field of civil and hydraulic engineering, and particularly to a continuous steel cage vertical correction and anti-floating device and a using method thereof. Background Technique

[0002] When constructing a steel cage pile foundation in a soft sedimentary stratum at the land-sea interface, it is usually necessary to use a steel cage with a relatively large length. Due to reasons such as limited bearing capacity of the soft stratum, complex geological conditions, and large groundwater pressure, the verticality and stability of the steel cage are easily severely affected during the construction process. When hoisting or inserting it into the construction trench, it is prone to shaking, tilting, or deviation. Due to the poor supporting ability of the stratum, it is difficult for the steel cage to maintain an accurate vertical state. If the deviation of the steel cage is too large during the lowering process, it may not be able to be smoothly inserted into the trench or the deviation is greater than the specification requirements, affecting the construction quality. Moreover, the steel cage is easily affected by the upward buoyancy force, especially during the concrete pouring process, the buoyancy effect of the slurry and concrete increases significantly. If the steel cage floats, it may cause deviation from the designed position, affecting the verticality of the pile body and the overall project quality. Summary of the Invention

[0003] The purpose of the present invention is to provide a continuous steel cage vertical correction and anti-floating device and a using method thereof to solve the problems raised in the above background technique.

[0018] A second arc-shaped tooth plate is inserted on the outer wall of the base, and the inner tooth surface of the second arc-shaped tooth plate is meshed with the other transmission gear.

[0019] Preferably, the airbag is filled with a liquid buffer.

[0020] Preferably, the first arc-shaped tooth plate and the second arc-shaped tooth plate are placed opposite to each other and arranged in a relatively staggered manner.

[0021] Preferably, the power mechanism includes:

[0022] A power cavity is sleeved on the outer wall of the base tube, and the power cavity is communicated with the airbag;

[0023] A power tube is sleeved on the outer wall of the base tube, and the bottom end of the power tube is slidably connected in the power cavity;

[0024] A collar is sleeved on the outer wall of the base tube, and the collar is fixedly connected to the power tube;

[0025] A return spring is arranged on the outer wall of the power tube, and the return spring is located between the collar and the power cavity.

[0026] Preferably, the locking mechanism includes:

[0027] A locking block, the locking block has a triangular structure, the bottom end of the locking block is self-resetting and hinged on the outer wall of the collar, and a through groove is opened at the corresponding position on the outer wall of the collar;

[0028] A top block, the bottom end of the top block is hinged on the top surface of the collar in the upper power mechanism, the top block has a wedge-shaped structure, and the top block abuts against the side wall of the locking block;

[0029] An auxiliary block is arranged on the link mechanism, and the auxiliary block moves in the same rotation plane as the top block.

[0030] Preferably, the elastic force of the return spring is less than the driving force required for the locking block to lock the steel cable.

[0031] Preferably, two groups of elastic protrusions are arranged on the outer wall of the base pipe. The two groups of elastic protrusions are mirror-symmetrically distributed. The elastic protrusion above the airbag is located between the power mechanism and the locking mechanism, and the elastic protrusions below the airbag are mirror-symmetrically arranged with the central plane of the base pipe as the axis of symmetry.

[0032] Preferably, the elastic force of the return spring is less than the force required for the deformation of the elastic protrusion.

[0033] Preferably, the upper end of the base pipe is a variable-diameter structure, and the inner diameter of the upper end of the base pipe is greater than the outer diameter of the lower end of the base pipe.

[0034] A method for using a continuous steel cage vertical correction anti-floating device includes the following steps:

[0035] S1. detachably install the anchoring device on the seabed base, and connect the bottom end of the steel cable to the anchoring device;

[0036] S2. first center the correction device inside the steel cage so that the base pipe is on the axis of the steel cage;

[0037] S3. pass the steel cable through the base pipe, and keep the top end of the steel cable fixed and taut to ensure the vertical state of the device;

[0038] S4. slowly lower the steel cage using a hoisting device, ensuring that the correction device remains vertical and sinks with the steel cage;

[0039] S5. when the steel cage is immersed to the specified depth, the airbag is squeezed, pushing the collar, cooperating with the top block and the auxiliary block, so that the locking block rotates into the inner cavity of the base pipe and abuts against the outer wall of the steel cable, thereby realizing the fixation of the correction device;

[0040] S6. after pouring enough casting material at the bottom end of the steel cage, the anchoring device is separated from the seabed base, control the steel cable to move upward, and the anchoring device moves upward synchronously;

[0041] S7. when the bottom end of the correction device is squeezed upward by the anchoring device, the linkage mechanism flips. While the first arc-shaped tooth plate and the second arc-shaped tooth plate rotate into the base, the base moves downward, and the correction device is separated from the steel cage until the anchoring device and all the correction devices are out of the water surface.

[0042] The continuous steel cage vertical correction anti-floating device and the using method proposed by the present invention have the beneficial effects that:

[0043] The present invention utilizes the synergistic effect of the steel cable and the anchoring device, and precisely vertically pulls and fixes the top end of the steel cable to ensure that the steel cable is always in a taut state in water, thereby providing good axial support and vertical control effects. When the steel cable is in a taut state, even under the interference of water flow, buoyancy or other external forces in the sea, it can still maintain good stability and precise verticality. In addition, the two mirror-distributed link mechanisms in the device, through the mutual cooperation with the first arc-shaped tooth plate and the second arc-shaped tooth plate, accurately install the correction device in the internal structure of the steel reinforcement cage. The symmetric setting of the link mechanism can provide a uniform force distribution, thereby improving the overall stability and control accuracy of the device. During the installation process of the correction device, by setting the base pipe on the central axis of the steel reinforcement cage and making the axis of the base pipe coincide with the axis of the steel reinforcement cage, when the steel cable penetrates the base pipe and the steel reinforcement cage sinks below the sea surface through the hoisting equipment, based on the always-taut state of the steel cable, it can ensure that the steel reinforcement cage sinks in the water at the same inclination angle and movement trajectory as the steel cable. The advantage of this structural design is that whether during the sinking process or after reaching the predetermined depth, the steel reinforcement cage can maintain verticality or the required inclination degree of the design, thereby significantly improving the installation accuracy and correction effect of the steel reinforcement cage.

[0054] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0055] Please refer to Figures 1-9 , the present invention provides a technical solution for a continuous steel reinforcement cage vertical calibration and anti-floating device and its use method. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0056] A continuous steel reinforcement cage vertical calibration and anti-floating device includes: a steel cable 1, an anchoring device 2, and a calibration device 3.

[0057] The steel cable 1 is used to provide penetrating support and vertical traction to ensure that the entire device can maintain an accurate vertical state in water, and to achieve the overall sinking and recovery in cooperation with the anchoring device 2. Through the traction of the steel cable 1, it is ensured that the steel reinforcement cage 4 maintains stability and accuracy during the sinking process in the sea, thereby preventing deviation and inclination. The anchoring device 2 is connected to the bottom end of the steel cable 1, and the anchoring device 2 is detachably connected to the bottom end of the steel cable 1. The anchoring device 2 can be fixed on the seabed and automatically separated from the seabed base 5 by controlling the steel cable 1 after reaching the construction depth. The design of the anchoring device 2 ensures that the steel reinforcement cage 4 can be accurately positioned and maintained at the specified depth, effectively preventing the floating phenomenon caused by buoyancy or water flow. At the same time, the detachable design of the anchoring device 2 enables it to have the characteristic of being reusable, thereby improving the construction efficiency and reducing the cost. The correction device 3 is connected to the outer wall of the steel cable 1. Through the close connection with the steel cable 1, the correction device 3 ensures that the device can maintain the same movement trajectory as the steel cable 1 in water, and makes the steel cable 1 in a taut state by pulling the steel cable 1, thereby enhancing the stability of the correction device 3.

[0058] The correction device 3 includes: a base tube 301, an airbag 302, two power mechanisms 303, a locking mechanism 304, two link mechanisms 305, a base 306, two power gears 307, two transmission gears 308, a first arc-shaped tooth plate 309, and a second arc-shaped tooth plate 310.

[0059] The base pipe 301 is sleeved on the outer wall of the steel cable 1. The base pipe 301 is connected to the steel cable 1 in a sleeved manner and is centrally arranged in the internal structure of the reinforcement cage 4 to ensure that the base pipe 301 is on the axis of the reinforcement cage 4. The setting of the base pipe 301 can provide good support and positioning functions. The airbag 302 is centrally arranged on the outer wall of the base pipe 301. The airbag 302 is used to cause the airbag 302 to deform and be flattened under the continuous action of the external water pressure after the reinforcement cage 4 sinks to an appropriate depth, thereby triggering the pressure-induced flow of the internal filler. Two power mechanisms 303 are mirror-symmetrically arranged at both ends of the airbag 302 to provide balanced power output. The mirror-symmetric structural design can effectively reduce the offset caused by uneven stress. The locking mechanism 304 is arranged on the upper power mechanism 303. The locking mechanism 304 realizes the locking and unlocking operations of the steel cable 1 through cooperation with the power mechanism 303. The locking mechanism 304 can be automatically locked after the device reaches the predetermined depth and can be automatically reset under the control of the power mechanism 303 when unlocking. Two link mechanisms 305 are mirror-connected to the two power mechanisms 303. The base 306 is connected to the distal end of the link mechanism 305 away from the power mechanism 303. The interior of the base 306 has a cavity structure for accommodating and installing a transmission system composed of a power gear 307 and a transmission gear 308, and for limiting the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 to ensure that the movement paths of the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 meet the requirements. Two power gears 307 are coaxially rotatably installed in the inner cavity of the base 306. Two transmission gears 308 are mirror-installed in the inner cavity of the base 306 and are respectively meshed with the two power gears 307. The first arc-shaped tooth plate 309 is inserted on the outer wall of the base 306, and the outer tooth surface of the first arc-shaped tooth plate 309 is meshed with one of the transmission gears 308. The second arc-shaped tooth plate 310 is inserted on the outer wall of the base 306, and the inner tooth surface of the second arc-shaped tooth plate 310 is meshed with the other transmission gear 308.

[0060] The interior of the airbag 302 is filled with a liquid buffer or a high-viscosity filler, such as silicone oil, polymer solution, or a liquid medium with stable flow characteristics. After the device sinks to the predetermined depth, the external water pressure gradually increases to the designed critical value. At this time, the airbag 302 is compressed and gradually deforms and shrinks. However, under the action of the filler, there is a time difference from the initial compression to the complete compression of the airbag 302. This time difference allows the reinforcement cage 4 to completely descend to the required depth. After standing for a certain period of time, the locking mechanism 304 is locked in cooperation with the power mechanism 303 to complete the position fixing of the calibration device 3 and the steel cable 1. Along the axial length of the reinforcement cage 4, several calibration devices 3 are arranged. According to different diving depths, different airbags 302 are selected to change the critical value of the airbag 302 being compressed.

[0061] The first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 are placed opposite to each other and arranged in relative dislocation. The outer shape curvatures of the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 are the same. The inner sides of the arcs of the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 face each other to ensure that a closed space can be formed between the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 and the outer wall of the base 306. This closed space is used to place the steel bars in the horizontal position of the steel reinforcement cage 4, thereby realizing the fixation of the calibration device 3. At the same time, the purpose of the dislocation distribution is that, by the cooperation of the two driving gears 307 and the two transmission gears 308, the opening and closing of the above-mentioned closed space can be realized. At the same time, when the two driving gears 307 and the two transmission gears 308 are allowed to rotate within a certain range, the above-mentioned closed space always remains closed. The end face of the first arc-shaped tooth plate 309 and the end face of the second arc-shaped tooth plate 310 are not in contact, being in a dislocation closed state. In the closed state, hard fixation can be avoided, that is, when the above-mentioned closed space is in the closed state, there is still a movable space between the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310, and there is still the ability of relative movement between the two arc-shaped tooth plates, thereby avoiding part wear or damage caused by hard fixation.

[0062] The power mechanism 303 includes: a power chamber 3031, a power pipe 3032, a collar 3033 and a return spring 3034.

[0063] The power chamber 3031 is sleeved on the outer wall of the base pipe 301 and is communicated with the airbag 302. When the airbag 302 is compressed under the action of water pressure, the internal filler is introduced into the power chamber 3031 through the diversion channel or conduit. The function of the power chamber 3031 is to transfer the pressure of the filler to the power pipe 3032, thereby generating a driving force. The power pipe 3032 is sleeved on the outer wall of the base pipe 301, and the bottom end of the power pipe 3032 is slidably connected in the power chamber 3031. The power pipe 3032 can reciprocate along the axis direction of the base pipe 301 to convert the pressure of the filler into mechanical displacement. The collar 3033 is sleeved on the outer wall of the base pipe 301 and is fixedly connected to the power pipe 3032. The return spring 3034 is arranged on the outer wall of the power pipe 3032 and is located between the collar 3033 and the power chamber 3031. The return spring 3034 can move the collar 3033 away from the airbag 302.

[0064] The link mechanism 305 is used to transfer the movement of the power mechanism 303 to the base 306 and the gear system, thereby realizing the driving of the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310. The link mechanism 305 includes: a first rod 3051, a second rod 3052 and a third rod 3053.

[0065] The first end of the first rod 3051 is hinged to the upper collar 3033. The second end of the first rod 3051 passes through the base 306 and is connected to two power gears 307. A hole slot for the movement of the first rod 3051 is provided on the outer wall of the base 306 (not shown in the figure). The hinged connection provides a rotational degree of freedom of movement, enabling the first rod 3051 to make corresponding angular adjustments according to the movement of the collar 3033. Through the transmission action of the first rod 3051, the two power gears 307 can rotate and mesh synchronously, thereby achieving precise control of the arc-shaped tooth plate. The first end of the second rod 3052 is fixedly connected to the lower collar 3033. The second rod 3052 serves as a fixed support component in the link mechanism 305, providing a stable fulcrum for the third rod 3053. When the collar 3033 moves away from the airbag 302, the second rod 3052 remains in its fixed position. The first end of the third rod 3053 is hinged to the second end of the second rod 3052, and the second end of the third rod 3053 is fixedly connected to the outer wall of the base 306. During the movement of the collar 3033, the angle between the third rod 3053 and the second rod 3052 changes. When the device is in a non-operating state or the pressure of the filler decreases, the elastic force generated by the return spring 3034 pushes the collar 3033 in the direction away from the airbag 302. When the return springs 3034 of the two power mechanisms 303 respectively push the two collars 3033 in the direction away from the airbag 302, the two link mechanisms 305 change. The angle between the first rod 3051 and the third rod 3053 gradually increases. As the angle between the first rod 3051 and the third rod 3053 increases, the movement of the first rod 3051 drives the power gear 307 to rotate. The power gear 307 meshes with the transmission gear 308, driving the synchronous movement of the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310. Through the cooperation of the link mechanism 305 and the gear system, the closing of the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 can be precisely controlled. During installation and disassembly, the two collars 3033 can be moved in the reverse direction to open the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310, that is, the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 move into the inner cavity of the base 306. At the same time, the first rod 3051, the second rod 3052, and the third rod 3053 form a retracting effect similar to an umbrella structure during the movement process, enabling the link mechanism 305 and the arc-shaped tooth plate to be concentrated in a smaller space, facilitating the withdrawal of the device.

[0066] The locking mechanism 304 includes: a locking block 3041, a top block 3042, and an auxiliary block 3043.

[0067] The locking block 3041 has a triangular structure to provide stable locking and unlocking functions.

[0068] The bottom end of the lock block 3041 is connected to the outer wall of the collar 3033 of the base pipe 301 through a hinge structure. The hinge structure is used to enable the lock block 3041 to rotate around its connection point when subjected to an external force. At the same time, a self-resetting member is provided at the hinge structure. This self-resetting member has an elastic recovery function and can automatically restore the lock block 3041 to its initial position after the external force is removed, thereby ensuring that the lock block 3041 has an automatic reset function.

[0069] A through groove is provided at the corresponding position on the outer wall of the base pipe 301. The existence of the through groove provides a rotation space and a movement path for the lock block 3041. When the top block 3042 and the auxiliary block 3043 act on the lock block 3041 together, the lock block 3041 can rotate around the hinge point, thereby realizing the locking function. The bottom end of the top block 3042 is hinged to the top surface of the collar 3033 in the upper power mechanism 303. Through its connection with the collar 3033, the top block 3042 can move synchronously with the movement of the power mechanism 303. When the collar 3033 moves, the wedge-shaped structure of the top block 3042 can generate an increasingly large abutting force, thereby pushing the lock block 3041 to rotate or reset. The top block 3042 has a wedge-shaped structure to facilitate a stable abutting relationship with the side wall of the lock block 3041. The top block 3042 abuts against the side wall of the lock block 3041. The auxiliary block 3043 is arranged on the first support rod 3051 and moves in the same rotation plane as the top block 3042. When the two return springs 3034 are in a natural state, that is, when the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 are in a closed state, the auxiliary block 3043 is located on one side of the lock block 3041. When the top block 3042 moves upward with the collar 3033, the top block 3042 contacts the lock block 3041. Since the bottom end of the top block 3042 is hinged, at this time, the top block 3042 will deflect toward the auxiliary block 3043. When the top block 3042 contacts the auxiliary block 3043, the force is applied to the lock block 3041, which will push the lock block 3041 to rotate inward toward the base pipe 301 until it abuts against the steel cable 1 to complete the fixation. When the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 move to the open state, the link mechanism 305 will be in a retracted state, and the auxiliary block 3043 will move away from the lock block 3041. After the support of the auxiliary block 3043 is missing, the top block 3042 cannot exert a continuous pressure on the lock block 3041. Under its own self-resetting ability, the lock block 3041 will rotate to disengage from the steel cable 1 to complete the separation of the calibration device 3 from the steel cable 1.

[0070] The elastic force of the reset spring 3034 is less than the driving force required for the locking cable 1. The elastic force of the reset spring 3034 causes the first rod 3051 and the third rod 3053 to be in an open state, that is, the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 are in a closed state, fixing the calibration device 3 inside the steel reinforcement cage 4. At this time, the locking mechanism 304 is not operating, and the cable 1 can move freely within the base pipe 301.

[0071] Two groups of elastic protrusions 311 are provided on the outer wall of the base pipe 301. The two groups of elastic protrusions 311 are mirror-symmetrically distributed. The elastic protrusion 311 located above the airbag 302 is between the power mechanism 303 and the locking mechanism 304, realizing the limitation of the position of the collar 3033. When the two collars 3033 are pushed by the two reset springs 3034 to abut against the two groups of elastic protrusions 311, the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 are in a closed state. When the airbag 302 is compressed, the generated driving force will cause the collar 3033 to squeeze the elastic protrusion 311, and when passing through the elastic protrusion 311, the locking mechanism 304 will operate to fix the calibration device 3 and the cable 1.

[0072] The elastic force of the reset spring 3034 is less than the force required for the deformation of the elastic protrusion 311, avoiding the driving collar 3033 from passing over the elastic protrusion 311 under the elastic force of the reset spring 3034, resulting in the operation of the locking mechanism 304 at an inappropriate position.

[0073] The upper end of the base pipe 301 is a variable-diameter structure. The inner diameter of the upper end of the base pipe 301 is greater than the outer diameter of the lower end of the base pipe 301. Since the axial length of the steel reinforcement cage 4 is relatively long, several calibration devices 3 are required. After the installation of the steel reinforcement cage 4 is completed, several calibration devices 3 need to be retracted. At this time, the top end of the base pipe 301 of the calibration device 3 located below can be inserted into the bottom end of the base pipe 301 located above, pushing the corresponding collar 3033 to separate the calibration device 3 from the steel reinforcement cage 4.

[0074] The anchoring device 2 includes: a chassis 201, a plug 202, a riser 203, a sliding ring 204, a support arm 205, an elastic member 206, a clamping plate 207, an upper cover 208, a sealing ring 209, a pressing plate 210, a guide rod 211, a plug rod 212, and a reset member 213.

[0075] The chassis 201 has an open-top disc structure. There are at least three sockets on the vertical outer wall for the insertion and telescoping of the insertion block 202. The chassis 201 provides a stable support structure and forms an integral connection with components such as the riser pipe 203 and the insertion block 202. The insertion block 202 is inserted into the socket of the chassis 201 and can move out or retract under the drive of the slip ring 204. The end of the insertion block 202 has a conical or wedge-shaped structure, which is convenient for inserting into the U-shaped ring 6 or closely contacting the seabed base 5 to achieve a stable anchoring effect. The riser pipe 203 is vertically arranged at the center position of the chassis 201 and is detachably connected to the steel cable 1. The riser pipe 203 provides guiding support for the movement of the slip ring 204 and provides structural support for the entire anchoring device 2. The slip ring 204 is sleeved on the outer wall of the riser pipe 203 and can move up and down along the axial direction of the riser pipe 203. The movement of the slip ring 204 controls the extension and retraction of the insertion block 202, and realizes the control of the anchoring device 2 through cooperation with the insertion block 202. One end of the support arm 205 is hinged to the outer wall of the slip ring 204, and the other end is hinged to the insertion block 202. The support arm 205 swings during the up and down movement of the slip ring 204, thereby driving the telescopic movement of the insertion block 202. The elastic member 206 is arranged on the bottom surface of the slip ring 204 and forms an elastic support structure with the slip ring 204. The elastic member 206 provides a restoring force for the slip ring 204 to ensure that the slip ring 204 can automatically move up and drive the insertion block 202 to retract after the clamping plate 207 is released. The bottom end of the clamping plate 207 is elastically connected to the chassis 201 and has a T-shaped structure. The protruding part of the side wall of the clamping plate 207 abuts against the upper wall surface of the slip ring 204 to limit the movement of the slip ring 204. The top surface of the clamping plate 207 is designed as an inclined surface to facilitate precise cooperation with the inclined surface of the insertion rod 212. The upper cover 208 is arranged on the top surface of the chassis 201 and is aligned with the center of the chassis 201. The top surface of the pressure plate 210 above the upper cover 208 is designed as a conical structure, that is, it gradually expands outward from the center position to form an inclined surface, and its outer diameter gradually increases to form a protruding conical curved surface. This structure is convenient for reducing resistance when pulling out in the grouting material, promoting the natural sliding of the grouting material along the inclined surface, preventing adhesion and blockage. At the same time, a push ring 214 is fixedly arranged at the top end of the upper cover 208, and the push rod 214 moves synchronously with the upper cover 208. The push ring 214 is used to contact the lower sleeve ring 3033 after the anchoring device 2 contacts the base pipe 301, so as to realize the pushing of the sleeve ring 3033. The sealing ring 209 is arranged at the edge of the top surface of the upper cover 208 and forms a circular contact with the pressure plate 210. The function of the sealing ring 209 is to prevent the grouting material from entering the space between the pressure plate 210 and the upper cover 208 and provide an effective sealing effect. The pressure plate 210 is arranged on the sealing ring 209 and is connected to the upper cover 208 through the guide rod 211. The pressure plate 210 provides a pressing and supporting effect on the entire device and cooperates with the reset member 213 for movement. The guide rod 211 is arranged on the bottom surface of the pressure plate 210, and the bottom end of the guide rod 211 penetrates the upper cover 208.The bottom diameter of the guide rod 211 is larger than the upper diameter, forming a limiting structure to ensure that the pressing plate 210 moves along a predetermined path. The guide rod 211 provides guiding and limiting functions for the pressing plate 210, ensuring that the plug rod 212 can accurately cooperate with the clamping plate 207. The plug rod 212 is arranged on the bottom surface of the pressing plate 210 and corresponds to the position of the clamping plate 207. The bottom end of the plug rod 212 is designed as an inclined surface to facilitate precise abutment with the top surface of the clamping plate 207. The upper cover 208 is provided with a socket for the plug rod 212 to insert, ensuring that the movement path of the plug rod 212 is accurate. The reset member 213 is arranged between the upper cover 208 and the pressing plate 210, providing support and automatic reset functions for the pressing plate 210. The function of the reset member 213 is to keep the pressing plate 210 in the upper position by providing an elastic force. When the pressure of the grouting material reaches the set threshold, the elastic force of the reset member 213 is overcome, and the pressing plate 210 moves downward. When the grouting material pressure decreases or is released, the reset member 213 can make the pressing plate 210 automatically reset and return to the original position. The U-shaped rings 6 are arranged on the seabed base 5 to provide a stable anchor point for the anchoring device 2. When the insertion block 202 of the anchoring device 2 is inserted into the U-shaped ring 6, through mechanical connection, the anchoring device 2 can be effectively prevented from sliding or falling off on the seabed base 5. The distribution of the U-shaped rings 6 is usually annular or symmetrically distributed. Multiple U-shaped rings 6 can provide multi-point support and improve the overall stability of the anchoring device 2. In complex seabed terrains, this design can effectively resist displacement or inclination caused by water flow, buoyancy or other external forces.,

[0076] A method for using a continuous steel cage vertical correction anti-floating device includes the following steps:

[0077] S1. Detachably install the anchoring device 2 on the seabed base 5. A plurality of annularly distributed U-shaped rings 6 are preset on the seabed base 5 to provide fixation and stability for the anchoring device 2. The insertion block 202 of the anchoring device 2 is mechanically connected to the U-shaped ring 6, thereby forming a multi-point support structure to prevent the anchoring device 2 from generating lateral sliding or falling off during the installation process. Connect the bottom end of the steel cable 1 to the top of the riser pipe 203 of the anchoring device 2, and realize the quick docking and separation of the steel cable 1 and the anchoring device 2 through a detachable connection mechanism. Through the cooperative action of the elastic member 206 and the sliding ring 204 of the anchoring device 2, the insertion block 202 can automatically insert into the U-shaped ring 6 to achieve preliminary fixation.

[0078] S2. First, centrally arrange the correction device 3 inside the steel cage 4 to ensure that the base pipe 301 is on the axis of the steel cage 4. The base pipe 301 is docked or fixed with the support structure inside the steel cage 4 to ensure that it will not deviate from the center position of the steel cage 4 during subsequent operations. The correction device 3 and the steel cage 4 are positioned through a clamping structure or a clamping connection structure to maintain the stability of the device during the sinking process.

[0079] S3. Thread the steel cable 1 through the base pipe 301, and keep the top end of the steel cable 1 fixed and taut to ensure the vertical state of the device. The top of the steel cable 1 is controlled by a mechanical device or a winch to keep the steel cable 1 in a taut state and ensure its verticality during the entire sinking process. By adjusting the steel cable 1 in real time, ensure that the reinforcement cage 4 is aligned with the seabed base 5 in axis during the entire sinking process.

[0080] S4. Use the hoisting equipment to slowly lower the reinforcement cage 4, ensure that the calibration device 3 remains vertical and sinks with the reinforcement cage 4. During the sinking process of the reinforcement cage 4, the linkage mechanism 305, the base 306 and the arc-shaped tooth plate and other components of the calibration device 3 keep cooperating and operating. By controlling the taut state of the steel cable 1 and the lowering speed of the hoisting equipment, realize the smooth sinking of the reinforcement cage 4.

[0081] S5. When the reinforcement cage 4 sinks to the specified depth, the airbag 302 is gradually squeezed under the action of the external water pressure. The filling materials inside the airbag 302, such as liquid buffer or high-viscosity filler, enter the power chamber 3031 through the conduit, forming a driving force for the power mechanism 303. Under the action of the driving force, the collar 3033 of the power mechanism 303 moves, drives the linkage mechanism 305 to cooperate with the base 306, controls the closing of the arc-shaped tooth plate, and the cooperation of the top block 3042 and the auxiliary block 3043 drives the locking block 3041 to rotate into the inner cavity of the base pipe 301 and abut against the outer wall of the steel cable 1, thereby realizing the fixation of the calibration device 3.

[0082] S6. Pour a sufficient amount of casting material or concrete at the bottom end of the reinforcement cage 4 to ensure the fixation of the reinforcement cage 4 on the seabed. Through the synergistic action of the sealing ring 209 and the pressure plate 210, prevent the casting material from entering the internal components of the anchoring device 2, thereby ensuring the normal operation of the device. When the pressure of the casting material reaches the preset threshold, the pressure plate 210 gradually sinks under the support of the reset member 213, thereby triggering the separation mechanism of the anchoring device 2. By controlling the upward movement of the steel cable 1, the anchoring device 2 moves upward synchronously and disengages from the seabed base 5.

[0083] S7. After the bottom end of the calibration device 3 is upwardly extruded by the anchoring device 2, the linkage mechanism 305 flips, and the first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 rotate into the inner cavity of the base 306 under the cooperation of the power gear 307 and the transmission gear 308. At the same time, the base 306 moves downward to realize the separation of the calibration device 3 from the steel reinforcement cage 4. Under the elastic force of the two return springs 3034, the collar 3033 moves away from the airbag 302, increasing the angle between the first strut 3051 and the third strut 3053, thereby promoting the closing of the arc-shaped tooth plate and the movement of the base 306. The linkage mechanism 305 forms an effect similar to the closing of an umbrella during the movement, concentrating the device in a smaller space, facilitating the withdrawal and reuse of the device. After the recovery of the device, the steel cable 1, the anchoring device 2, and the calibration device 3 can be installed and used again, improving the construction efficiency and economy.

[0084] Working principle:

[0085] In the construction preparation stage, the anchoring device 2 is installed on the seabed base 5. There are several U-shaped rings 6 distributed annularly on the seabed base 5, which are used to provide fixation and support for the anchoring device 2. The insertion block 202 of the anchoring device 2 is inserted into the U-shaped ring 6 through the control of the sliding ring 204, forming a multi-point support structure to prevent the anchoring device 2 from sliding or shifting on the seabed. The calibration device 3 is sleeved on the outer wall of the steel cable 1 through the base pipe 301 and is placed in the internal structure of the steel reinforcement cage 4 in the center, ensuring that the base pipe 301 is on the axis of the steel reinforcement cage 4. Before the construction starts, the steel cable 1 is tightened by the hoisting equipment to ensure that the device maintains an accurate vertical state during the sinking process. The steel reinforcement cage 4 is slowly lowered by the hoisting equipment so that it sinks synchronously with the steel cable 1. During the sinking process of the calibration device 3, through the cooperation of the connecting rod mechanism 305 and the gear system, the relative position with the steel reinforcement cage 4 remains unchanged, thereby ensuring that the steel reinforcement cage 4 always maintains the designed vertical direction during the entire sinking process. When the steel reinforcement cage 4 sinks to the predetermined depth, the external water pressure gradually increases and acts on the airbag 302. The external water pressure causes the airbag 302 to gradually deform and shrink, and the internal filler (such as a liquid buffer or a high-viscosity filler) is squeezed into the power cavity 3031. The filler enters the power cavity 3031 through the conduit, thereby pushing the power pipe 3032 to move upward or downward. Under the driving force generated by the power mechanism 303, the collar 3033 moves, squeezes the elastic protrusion 311, and crosses the elastic protrusion 311. At the same time, the top block 3042 and the auxiliary block 3043 cooperate with each other to generate a force to drive the locking block 3041 to rotate into the inner cavity of the base pipe 301. After rotation, the locking block 3041 contacts the outer wall of the steel cable 1, thereby realizing the locking and positioning of the steel reinforcement cage 4. After the locking mechanism 304 completes the locking, the casting material (such as concrete or slurry) is poured into the bottom end of the steel reinforcement cage 4. The pressure of the casting material gradually increases. When the pressure of the casting material reaches the preset threshold value, the pressure plate 210 gradually sinks under the support of the reset member 213, triggering the separation mechanism of the anchoring device 2. The pressure plate 210 moves downward, the reset member 213 is compressed, the bottom end of the insertion rod 212 abuts against the top end of the clamping plate 207, the clamping plate 207 deflects outward, and the sliding ring 204 moves upward under the action of the elastic member 206, thereby driving the insertion block 202 to move into the inner cavity of the chassis 201. When the casting material reaches the set depth and pressure, the anchoring device 2 is separated from the seabed base 5. The steel reinforcement cage 4 is kept at the specified depth and position under the action of the casting material. After the anchoring device 2 is separated, under the lifting action of the steel cable 1, it moves upward synchronously along the steel cable 1 until it completely detaches from the seabed base 5. During the upward movement of the anchoring device 2, it contacts the bottom end of the lowermost calibration device 3 and upwardly squeezes the collar 3033 below the calibration device 3. The connecting rod mechanism 305 flips, and the angle between the first support rod 3051 and the third support rod 3053 becomes smaller. The first arc-shaped tooth plate 309 and the second arc-shaped tooth plate 310 move into the inner cavity of the base 306.During the movement of the linkage mechanism 305, an effect similar to the closing of an umbrella is formed, enabling the device to be concentrated in a smaller space, facilitating the withdrawal and reuse of the device. The distance between the base 306 and the diameter of the steel reinforcement cage 4 increases. Meanwhile, as the first strut 3051 rotates, the auxiliary block 3043 will separate from the top block 3042. At this time, the locking block 3041 will lack support force, and under the action of its own restoring force, the correction device 3 will separate from the steel cable 1. At the same time, the correction device 3 will rise with the anchoring device 2. Repeat the above steps to recycle several correction devices 3. After the fixation of the steel reinforcement cage 4 is completed, the automatic recycling of the device is achieved by controlling the upward movement of the steel cable 1 and the movement of the linkage mechanism 305. After one construction is completed, through the inspection and maintenance of the device, its reuse in the next construction can be realized. All components of the device are designed to be detachable, facilitating maintenance and replacement. By adjusting the type of the airbag 302 and the characteristics of the filling material, different undersea construction environments and depths can be adapted.,
