Description

Technical Field

[0002] Anchor cable support is often used in deep foundation pit support projects. The pull-out resistance of anchor cables is the friction between the anchor section and the surrounding soil. In some foundation pit projects, due to the particularity of the soil layer, the silt layer and sand layer are thick and the rock layer is very deep. When rotary bored piles are used in conjunction with anchor cable support, the length of the anchor cable into the rock must reach more than 55 meters. Considering that the prestress loss caused by the excessive length of the anchor cable, the pull-out resistance of the ordinary anchor cable cannot meet the design requirements, and designers mostly use the enlarged head anchor cable support solution to solve it.

In traditional methods, due to the difficulty of construction, errors or time waste may occur during the construction process. The applicability of traditional jet-jet anchor cables may be limited by different geological conditions.

Under the action of four groups of hinge rods, the shock-absorbing blocks form a stable mechanical structure with the external fixing sleeve and the anchor cable, which can effectively relieve vibrations. When the vibrations are transmitted to the inside of the device, the external fixing sleeve slides along the outer wall of the central sleeve through the rotation of the hinge rods.

[0016] 2. The present invention has a quick replacement mechanism: To solve the problem of the reduced effect of the shock-absorbing blocks due to wear during long-term use, a quick replacement mechanism is designed in the solution. This mechanism can quickly disassemble and replace the worn shock-absorbing blocks through a series of ingenious sliding and compressive deformation designs. When the hand-pushing sleeve slides, its additional channel is docked with the movable cone channel, releasing the restriction on the embedded balls, enabling the embedded sleeve to slide freely, so that the shock-absorbing block can be easily taken out and replaced. This design greatly improves the maintenance efficiency and avoids the time cost of equipment shutdown for maintenance.

The present invention has multiple data monitoring and real-time feedback: The system comprehensively monitors the working state of the cable anchor by integrating a variety of sensors and data collection units. These monitoring systems cover multiple key parameters, such as tensile force, dynamic load, internal corrosion condition, displacement, acoustic wave, and electromagnetic data.

[0018] 4. The present invention has data processing and intelligent analysis: Through the sorting and warehousing unit, the system classifies and stores the data collected from each sensor, providing a reliable data source for subsequent data analysis. The data will enter the visual analysis module, and the data is processed through the developed software and algorithms. Specific algorithms include screening out key data from a large amount of data, removing noise to ensure the accuracy of analysis, and setting parameter thresholds to ensure the accurate assessment of the cable anchor state. The algorithm can detect whether there are abnormalities, such as overloading or excessive wear, etc. According to the working conditions of the cable anchor, relevant algorithm formulas are developed and tested to ensure that the algorithm can accurately reflect the actual working state.

The rubber sleeve 43 is fixedly connected to the outer surface of the central sleeve 1, and a circular contact groove 44 is arranged in the middle of the outer surface of the rubber sleeve 43. The docking shock-absorbing mechanism 5 is located on the central sleeve 1 and is on the same central axis as the docking and fixing mechanism 4. It cooperates with the central sleeve 1, the first side-mounted ring seat 2, the first side-mounted ring seat 2, the second side-mounted ring seat 3, the first docking ring sleeve 41, and the second docking ring sleeve 42 to ensure the stability during the installation of the anchor cable and reduce the vibration generated by the outside. The docking shock-absorbing mechanism 5 includes an outer fixing sleeve one 51, an outer fixing sleeve two 52, and a first snap ring 53. The outer fixing sleeve one 51 is slidably connected to the side wall of the central sleeve 1 and is located between the first docking ring sleeve 41 and the first side-mounted ring seat 2. The outer fixing sleeve two 52 is slidably connected to the side wall of the central sleeve 1 and is located between the first docking ring sleeve 41 and the second docking ring sleeve 42. The outer fixing sleeve one 51 and the outer fixing sleeve two 52 are provided with slots opening outward. A first snap ring 53 is arranged inside the outer fixing sleeve two 52 and the outer fixing sleeve one 51 and is sleeved on the outer surface of the central sleeve 1. The side wall of the outer fixing sleeve one 51 facing the outer fixing sleeve two 52 is fixedly connected with circumferentially distributed first hinge shaft seats 54. The outer fixing sleeve one 51 is rotationally connected with a first hinge rod 55 through the first hinge shaft seats 54. The side wall of the outer fixing sleeve two 52 facing the outer fixing sleeve one 51 is fixedly connected with circumferentially distributed second hinge shaft seats 56. The outer fixing sleeve two 52 is rotationally connected with a second hinge rod 57 through the second hinge shaft seats 56. One end of the second hinge rod 57 away from the second hinge shaft seat 56 is hinged to one end of the first hinge rod 55 away from the first hinge shaft seat 54. The central sleeve 1 fixes the central connection structure required for the anchor cable, and the docking shock-absorbing mechanism 5 cooperates with the docking and fixing mechanism 4 to perform structural shock absorption on the placed anchor cable. The outer fixing sleeve one 51 and the outer fixing sleeve two 52 slide in two opposite directions of the central sleeve 1 respectively. The first side-mounted ring seat 2 and the first docking ring sleeve 41 added to the central sleeve 1 directly limit the sliding distance and position of the outer fixing sleeve one 51. The second docking ring sleeve 42 and the rubber sleeve 43 directly limit the sliding distance and position of the outer fixing sleeve two 52. The outer fixing sleeve one 51 docks four rotatable first hinge rods 55 through four circumferentially arranged first hinge shaft seats 54 added. The outer fixing sleeve two 52 docks four rotatable second hinge rods 57 through four circumferentially arranged second hinge shaft seats 56 added. The four second hinge rods 57 and the first hinge rods 55 are also rotationally docked. The shock-absorbing blocks 58 added to all the first hinge rods 55 and the second hinge rods 57 are in direct contact with the placement area.The structure composed of anchor cables is protected by pushing from four directions. When the generated vibration is transmitted to the device, it will cause the displacement of the embedded sleeve 59, the fixed hinge rod one 55 and the hinge rod two 57. A relative rotational movement occurs between the hinge rod one 55 and the hinge rod two 57. The hinge rod one 55 drives the external fixed sleeve one 51 to slide along the outer wall of the central sleeve 1 by rotating the added hinge shaft seat one 54, and the hinge rod two 57 drives the external fixed sleeve two 52 to slide along the outer wall of the central sleeve 1 by rotating the added hinge shaft seat two 56. The snap ring one 53 installed inside the external fixed sleeve one 51 and the external fixed sleeve two 52 also undergoes compressive deformation along with the sliding displacement of the external fixed sleeve one 51 and the external fixed sleeve two 52 and the corresponding restrictions of the side-mounted ring seat one 2, the docking ring sleeve one 41, the docking ring sleeve two 42 and the side-mounted ring seat two 3. Cooperating with the moving external fixed sleeve two 52 and the external fixed sleeve one 51 to form a shock damping effect, the vibration is alleviated, and the anchoring ability of the device in a vibrating environment is improved.

[0023] Please refer to the appendix Figure 1 - appendix Figure 5The wear replacement mechanism 6 is located on the docking damping mechanism 5, and cooperates with the hinged shaft seat 1 54, the hinged rod 2 57 and the embedded sleeve 59 for quickly replacing the damping structure. The wear replacement mechanism 6 includes an access sleeve 61. The number of access sleeves 61 corresponds to the number of hinged rods 2 57 and is fixedly connected to the inner side of the hinged rod 2 57. The outer surface of the access sleeve 61 is slidably connected with a hand push sleeve 62, and the side wall of the access sleeve 61 is slidably connected with a retaining spring 2 63. The side of the access sleeve 61 away from the retaining spring 2 63 is provided with a circumferentially distributed movable cone groove 64, and the movable cone groove 64 is slidably connected with an embedded ball 65. The hand push sleeve 6 The upper part of the inner wall is provided with an additional groove 66, and the embedded ball 65 extends to the inside of the access sleeve 61 through the movable cone groove 64. When the shock absorbing block 58 is highly worn due to long-term use of the device, the shock absorbing block 58 can be quickly disassembled and replaced by using the wear replacement mechanism 6 installed on the hinge rod 1 55 and the hinge rod 2 57. By manually moving the hand push sleeve 62 corresponding to each set of wear replacement mechanism 6, the hand push sleeve 62 slides toward the end of the access sleeve 61. The sliding of the hand push sleeve 62 also drives the installed retaining spring 2 63 to be compressed and deformed. When the hand push sleeve 62 slides, the additional groove 6 installed on it is 6 is docked with the multiple groups of movable conical grooves 64 installed in the access sleeve 61, and the push sleeve 62 is also separated from the compacting contact with the embedded balls 65 sliding inside the movable conical grooves 64, so that each group of embedded balls 65 can slide inside the corresponding movable conical grooves 64. At this time, the protrusion of the embedded sleeve 59 installed on the shock-absorbing block 58 and inserted into the access sleeve 61 also releases the restriction of the protrusion of the embedded balls 65, so that the embedded sleeve 59 can slide freely inside the access sleeve 61. The shock-absorbing block 58 and the embedded sleeve 59 can be taken out, and the shock-absorbing block 58 in good condition can be replaced for installation, and the corresponding embedded The insertion sleeve 59 is inserted into the access sleeve 61, and the lower end protrusion of the embedded sleeve 59 extends below the embedded ball 65. At the same time, the held hand push sleeve 62 is released, and the deformed and compressed retaining spring 63 causes the hand push sleeve 62 to slide upward along the access sleeve 61. The additional groove 66 then disengages from each group of active conical grooves 64, and the hand push sleeve 62 then compacts each group of embedded balls 65 in the active conical grooves 64. The embedded balls 65 extend through the active conical grooves 64 to the protrusion of the access sleeve 61, which also restricts the embedded sleeve 59 in the access sleeve 61, and the shock absorbing block 58 corresponding to the embedded sleeve 59 is also fixed accordingly.

The tension data collection unit 71 measures the tensile force through tools such as a tensiometer and a mechanical sensor to ensure that the anchor cable is within the designed tension range. The dynamic load collection unit 72 monitors the dynamic load borne by the anchor cable by installing a load sensor or an accelerometer. Monitoring the change of the load can judge whether the anchor cable is overloaded or whether there is abnormal mechanical behavior. The acoustic wave data collection unit 73 detects the internal state of the anchor cable through ultrasonic waves or other acoustic wave technologies.

[0027] Working principle: First, the central sleeve 1 fixes the central connection structure required for the anchor cable, and the docking cushioning mechanism 5 cooperates with the docking fixing mechanism 4 to perform structural cushioning on the placed anchor cable, and the external fixing sleeve 1 51 and the external fixing sleeve 2 52 slide in two relative directions of the central sleeve 1 respectively, and the side ring seat 1 2 and the docking ring sleeve 1 41 installed on the central sleeve 1 directly limit the sliding distance and position of the external fixing sleeve 1 51, and the docking ring sleeve 2 42 and the rubber sleeve 43 directly limit the sliding distance and position of the external fixing sleeve 2 52, the external fixing sleeve 1 51 is docked with four groups of rotatable hinged rods 1 55 through four groups of annularly arranged hinged shaft seats 1 54, and the external fixing sleeve 2 52 is docked with four groups of rotatable hinged rods 1 55 through four groups of annularly arranged hinged shaft seats 2 56. The four groups of movable hinged rods 2 57 are also rotated and docked with the hinged rod 1 55. All hinged rods 1 55 and the shock-absorbing blocks 58 installed on the hinged rod 2 57 are in direct contact with the placement area, and the anchor cable structure is protected from top contact from four directions. When the generated vibration is transmitted to the equipment, the embedded sleeve 59 and the fixed hinged rod 1 55 and hinged rod 2 57 will be displaced, and the hinged rod 1 55 and the hinged rod 2 57 will perform relative rotational movement, and the hinged rod 1 55 drives the external fixed sleeve 1 51 to slide along the outer wall of the central sleeve 1 by rotating the installed hinged shaft seat 1 54, and the hinged rod 2 57 drives the external fixed sleeve 2 52 to slide along the outer wall of the central sleeve 1 by rotating the installed hinged shaft seat 2 56. The retaining spring 1 53 installed inside the external fixing sleeve 1 51 and the external fixing sleeve 2 52 also undergoes compression deformation with the sliding displacement of the external fixing sleeve 1 51 and the external fixing sleeve 2 52 and the corresponding restrictions of the side ring seat 2, the docking ring sleeve 1 41, the docking ring sleeve 2 42 and the side ring seat 2 3, and forms a shock-absorbing and damping effect with the moving external fixing sleeve 2 52 and the external fixing sleeve 1 51 to alleviate the vibration and improve the anchoring ability of the device in a vibration environment. When the shock-absorbing block 58 is highly worn due to long-term use of the device, the wear replacement mechanism 6 installed on the hinge rod 1 55 and the hinge rod 2 57 can be used to quickly disassemble and replace the shock-absorbing block 58, and the hand push sleeve 62 corresponding to each set of wear replacement mechanisms 6 can be manually pushed to move the hand push sleeve 62 to the access sleeve 61, the sliding of the hand push sleeve 62 also drives the installed retaining spring 2 63 to compress and deform. When the hand push sleeve 62 slides, the additional groove 66 installed on it docks with the multiple groups of movable conical grooves 64 installed on the access sleeve 61, and the hand push sleeve 62 also breaks away from the compacted contact with the embedded balls 65 sliding inside the movable conical grooves 64, so that each group of embedded balls 65 can slide inside the corresponding movable conical grooves 64. At this time, the protrusion of the embedded sleeve 59 installed on the shock-absorbing block 58 and inserted into the access sleeve 61 also releases the restriction of the protrusion of the embedded ball 65, so that the embedded sleeve 59 can slide freely inside the access sleeve 61, and the shock-absorbing block 58 and the embedded sleeve 59 can be taken out, and the shock-absorbing block 58 in good condition can be replaced for installation.And insert the corresponding embedding sleeve 59 into the access sleeve 61. The lower end protrusion of the embedding sleeve 59 extends below the embedding ball 65. At the same time, release the held hand push sleeve 62. The deformed and compressed second retaining spring 63 causes the hand push sleeve 62 to slide upward along the access sleeve 61. The additional channel 66 then disengages from each group of movable tapered grooves 64. Subsequently, the hand push sleeve 62 compacts each group of embedding balls 65 and locks them in the movable tapered grooves 64. The protrusion of the embedding balls 65 extending into the access sleeve 61 through the movable tapered grooves 64 will also restrict the embedding sleeve 59 within the access sleeve 61. The corresponding shock absorber block 58 of the embedding sleeve 59 is also fixed accordingly, thus achieving the ability of rapid disassembly and replacement. At the same time, the working state data of the anchor cable is collected by the detection and collection element 7. The tension data collection unit 71 measures the tensile force through tools such as a tensiometer and a mechanical sensor to ensure that the anchor cable is within the designed tension range. The dynamic load collection unit 72 monitors the dynamic load borne by the anchor cable by installing a load sensor or an accelerometer. Monitoring the change of the load can determine whether the anchor cable is overloaded or whether there are abnormal mechanical behaviors. The acoustic wave data collection unit 73 detects the internal state of the anchor cable through ultrasonic or other acoustic wave technologies. Ultrasonic technology can help detect whether there are cracks, cavities or other defects inside the anchor cable. The corrosion data collection unit 74 measures the corrosion potential of the anchor cable and evaluates the corrosion situation by using an electrochemical sensor or a current detection instrument. The displacement data collection unit 75 monitors the deformation and displacement of the anchor cable through a displacement sensor. The displacement of the anchor cable can be detected by installing sensors (such as a laser displacement meter, a displacement meter, etc.). The electromagnetic data collection unit 76 evaluates the internal state of the anchor cable by detecting the magnetic field change of the metal part of the anchor cable. This technology is mainly used to detect internal defects (such as cracks, looseness, etc.) of the anchor cable.
