Description

Technical Field

[0001] The present invention relates to the technical field of composite piles, and particularly to a fiber winding mechanism and a manufacturing device for composite piles. Background Art

[0002] A composite pile is a reinforced pile foundation formed by combining different materials or technologies. For example, the composite piles used in the field of ocean engineering usually include concrete pipe piles, and composite materials such as fibers are wound around the outer periphery of the pipe piles to achieve the performance of the composite piles against seawater impact, corrosion resistance, etc.

[0003] Such composite piles are large in volume and mass. For example, the composite piles used in ocean engineering usually have a length of more than ten meters and a mass of more than 5 tons. There are great difficulties in winding fibers around such large composite piles. If the fiber is to be wound around the outer periphery of the pipe pile, it is necessary to make the winding mechanism connected with the fiber rotate around the pipe pile, or make the pipe pile pass through the winding mechanism and rotate itself to wind the fiber connected to the winding mechanism on the surface of the workpiece.

[0004] However, precisely because of the large volume and mass of such pipe piles, they cannot be clamped by the clamping mechanism and kept rotating, and the fiber cannot be wound by the scheme of the pipe pile rotating itself. Therefore, the existing schemes usually keep the pipe pile fixed, and drive the fiber to be wound around the pipe pile by making the winding mechanism rotate around the pipe pile, and then apply materials such as resin outside the fiber. This method has defects such as uneven resin coating. After the resin is cured, the resin thickness at each position of the fiber layer is uneven, which affects the performance of the composite pile, and there are also defects such as weak bonding between the fiber layer and the pipe pile.

[0005] In summary, how to wind the fiber around a large pipe pile and ensure that materials such as resin are evenly distributed at each position of the fiber is an urgent problem to be solved. Summary of the Invention

[0006] Aiming at the above deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a fiber winding mechanism and a manufacturing device for composite piles, which are used to solve the problems that it is difficult to wind fibers around large pipe piles and ensure uniform resin coating in the prior art.

[0007] The technical solution adopted by the present invention to solve its technical problem is a fiber winding mechanism for winding fibers on the outer surface of a pipe pile. The fiber winding mechanism includes:

[0008] A rotatable rotating ring having a winding hole allowing the pipe pile to pass through;

[0009] The pre - impregnation unit stores pre - impregnation liquid. Fibers can penetrate into the pre - impregnation liquid and then pass through and be pulled to the outer surface of the pipe pile. The pre - impregnation unit is rotatably arranged on the swivel ring and rotates circumferentially along the pipe pile following the swivel ring to wind the fibers onto the outer surface of the pipe pile.

[0010] Wherein, the pre - impregnation unit rotates circumferentially along the pipe pile following the swivel ring, and the pre - impregnation unit can rotate relative to the swivel ring around its own axis, so that the angle between the pre - impregnation unit and the horizontal plane remains constant.

[0011] The present invention has at least the following beneficial effects:

[0012] The pipe pile passes through the winding hole of the swivel ring. The swivel ring rotates and drives the fibers to wind around the outer periphery of the pipe pile. By the pre - impregnation method, the fibers penetrate into the pre - impregnation liquid and then pass through. The pre - impregnation liquid can evenly cover the inner and outer sides of the fibers. When the fibers are wound on the pipe pile, the pre - impregnation liquid on the inner side of the fibers can play a bonding role, so that the fibers are firmly bonded to the peripheral wall of the pipe pile, enhancing the connection strength and improving the corrosion resistance, impact resistance and soil friction resistance of the composite pile. At the same time, the pre - impregnation unit is rotatably arranged on the swivel ring. During the process of rotating around the pipe pile following the swivel ring, the pre - impregnation unit can rotate relative to the swivel ring in the opposite direction, so that the pre - impregnation tank can always remain horizontal or at a constant angle with the horizontal plane, avoiding the leakage of the pre - impregnation liquid.

[0013] Furthermore, it further includes an angle - maintaining unit, which includes:

[0016] Furthermore, the speed - change gear set includes a follower gear meshing with the first gear ring, and the pre - impregnation unit is arranged on the follower gear;

The follower gear at the starting end of the speed - change gear set meshes with the first gear ring, and the pre - impregnation unit is arranged on the follower gear at the end of the speed - change gear set.

[0018] Furthermore, it further includes an angle - maintaining unit, which includes:

[0019] A cage rotatably arranged on the swivel ring, and the pre - impregnation unit is arranged on the cage;

[0021] Further, the prepreg unit includes a guide member having a guide opening through which the fiber can pass and be drawn to the pipe pile by the guide opening;

[0022] The length direction of the fiber between the guide opening and the pipe pile is the winding direction. The projection of the guide member along the winding direction is the first projection, and the projection of the fiber between the guide opening and the pipe pile along the winding direction is the second projection, and the second projection is on the outer edge of the first projection.

[0023] Further, the prepreg unit further includes a fiber storage rack for storing the fiber and a prepreg tank for containing the prepreg solution;

[0024] The upper end of the prepreg tank has an opening provided with a cover plate having an inlet and an outlet. The fiber on the fiber storage rack can penetrate into the prepreg tank through the inlet and penetrate out of the prepreg tank through the outlet.

[0025] Further, the prepreg unit includes a fiber storage rack for storing the fiber, a prepreg tank for containing the prepreg solution, and a guide member;

[0026] The fiber winding mechanism further includes a second driving motor for driving the swivel to rotate so as to pull the fiber on the fiber storage rack to sequentially pass through the prepreg tank and the guide member and wind it onto the pipe pile.

[0027] Further, a plurality of the prepreg units are provided on the swivel, and the plurality of prepreg units are evenly distributed along the circumferential direction of the winding hole.

[0045] Please refer to Figure 2 , this embodiment discloses a fiber winding mechanism 100 for winding fibers 500 on the outer surface of a pipe pile 200. The fiber winding mechanism 100 includes:

[0046] A rotatable rotating ring 120 having a winding hole allowing the pipe pile 200 to pass through;

[0047] A pre-impregnation unit 130 storing pre-impregnation liquid. The fibers 500 can be immersed in the pre-impregnation liquid and then drawn out and led to the outer surface of the pipe pile 200. The pre-impregnation unit 130 is rotatably arranged on the rotating ring 120 and rotates circumferentially along the pipe pile 200 following the rotating ring 120 to wind the fibers 500 onto the outer surface of the pipe pile 200;

[0048] Wherein, the pre-impregnation unit 130 rotates circumferentially along the pipe pile 200 following the rotating ring 120, and the pre-impregnation unit 130 can rotate relative to the rotating ring 120 around its own axis, so that the angle between the pre-impregnation unit 130 and the horizontal plane remains constant.

[0049] Specifically, in this embodiment, a rotating ring 120 is provided, and the pipe pile 200 passes through the winding hole of the rotating ring 120. The rotating ring 120 rotates and drives the fiber 500 to wind around the outer periphery of the pipe pile 200. By means of pre-impregnation, the fiber 500 is immersed in the pre-impregnation liquid and then penetrates out. The pre-impregnation liquid can uniformly cover the inner and outer sides of the fiber 500. When the fiber 500 winds around the pipe pile 200, the pre-impregnation liquid on the inner side of the fiber 500 can play a bonding role, so that the fiber 500 is firmly bonded to the peripheral wall of the pipe pile 200, enhancing the connection strength and improving the corrosion resistance, impact resistance and soil friction resistance of the composite pile.

[0050] It should be noted that the pre-impregnation liquid needs to be placed in the pre-impregnation tank 132, and the fiber 500 needs to enter the pre-impregnation tank 132 to be immersed in the pre-impregnation liquid to achieve pre-impregnation. However, the pre-impregnation tank 132 is usually fixedly arranged on the ground or in the factory building. If the pre-impregnated fiber 500 is wound into a roll, and then the wound fiber 500 roll is loaded into the fiber winding mechanism 100 for winding, the processes of winding, transporting and installing the fiber 500 require a lot of time. The fiber 500 cannot be wound around the pipe pile 200 in time, the pre-impregnation liquid may solidify in advance and cannot fit the pipe pile 200, and the fibers 500 are in contact with each other after winding, and the pre-impregnation liquid is squeezed out, seriously affecting the performance of the composite pile. If the pre-impregnated fiber 500 is directly pulled to the rotating ring 120, the fiber 500 passing through the rotating ring 120 can be wound around the pipe pile 200 orderly, but during the rotation of the rotating ring 120, the fiber 500 that has not passed through the ring cannot cross the pipe pile 200 and wind around the pipe pile 200, and orderly winding cannot be achieved.

[0051] Based on this, in this embodiment, the pre-impregnation unit 130 is arranged on the rotating ring 120 and rotates around the pipe pile 200 together with the rotating ring 120, so as to realize that the fiber 500 is quickly wound around the pipe pile 200 after being soaked in the pre-impregnation liquid in the pre-impregnation unit 130.

[0052] It can be understood that if the pre-impregnation unit 130 is fixedly connected to the rotating ring 120, there will be a problem that must be overcome during its revolution around the pipe pile 200 along with its rotation or understood as the flipping of the pre-impregnation unit 130: the pre-impregnation liquid is stored in the pre-impregnation tank 132. During the flipping process of the pre-impregnation unit 130, the pre-impregnation tank 132 will have a situation where the inclination angle is too large or even inverted. And the pre-impregnation tank 132 needs to allow the fiber 500 to continuously penetrate in and out, and it cannot be completely sealed. Therefore, when the inclination angle of the pre-impregnation tank 132 is too large or inverted, the pre-impregnation liquid will inevitably leak out in large quantities or completely, and continuous pre-impregnation of the fiber 500 cannot be achieved.

[0053] Based on this, in order to overcome the above problems in this embodiment, the impregnation unit 130 is rotatably arranged on the swivel ring 120. During the process of rotating around the pipe pile 200 with the swivel ring 120, the impregnation unit 130 can rotate relative to the swivel ring 120 in a direction opposite to the rotation direction of the swivel ring 120. Furthermore, the impregnation unit 130 can maintain a posture with a constant angle during the process of rotating around the pipe pile 200 following the swivel ring 120, avoiding the leakage of the impregnating liquid, so that this solution can be implemented continuously and smoothly. Among them, the constant angle between the impregnation unit 130 and the horizontal plane means that the angle between a certain component in the impregnation unit 130 and the horizontal plane is always constant and does not change with the rotation of the swivel ring 120. For example, the bottom surface of the impregnation tank 132 used to hold the impregnating liquid in the impregnation unit 130 has a constant angle with the horizontal plane, and this angle can be constantly maintained at 0° or other angles. When the angle is 0°, the bottom surface of the impregnation tank 132 is parallel to the horizontal plane.

[0054] Please refer to Figure 5 , in this embodiment, it includes an angle-holding unit, which includes:

[0055] A fixed ring 110, provided with a first toothed ring 111;

[0056] A variable-speed gear set, which meshes with the first toothed ring 111. The variable-speed gear set includes at least one follower gear 140 with a rotation direction opposite to that of the swivel ring 120, and the impregnation unit 130 is arranged on the follower gear 140.

[0057] Specifically, the fixed ring 110 is fixedly arranged, and the swivel ring 120 is rotatably arranged on the fixed ring 110. When the swivel ring 120 rotates, the variable-speed gear set meshing with the first toothed ring 111 rotates accordingly, and then drives the impregnation unit 130 to rotate self in a direction opposite to the rotation direction of the swivel ring 120, so that the impregnation unit 130 can maintain a posture with a constant angle during the process of rotating around the pipe pile 200 following the swivel ring 120.

[0058] Importantly, the power for the rotation of the follower gear 140 comes from the rotation of the swivel ring 120 itself. That is to say, when rotating the swivel ring 120, the follower gear 140 meshing with the first toothed ring 111 can be synchronously driven to rotate; when stopping the rotation of the swivel ring 120, the follower gear 140 also stops rotating; when the rotation speed of the swivel ring 120 changes, the rotation speed of the follower gear 140 also changes accordingly. That is, the follower gear 140 can follow the rotation, stop and change the rotation speed of the swivel ring 120 to achieve synchronous rotation, thereby ensuring that the impregnation unit 130 is always in a state with a constant angle at any time, and the impregnating liquid in the impregnation tank 132 will not pour out.

[0059] Please refer to Figure 2, in this embodiment, the speed-changing gear set includes a follower gear 140 meshing with the first gear ring 111, and the pre-impregnation unit 130 is disposed on the follower gear 140;

[0060] Alternatively, the speed-changing gear set includes a plurality of follower gears 140 meshing with each other in sequence, and the number of follower gears 140 is an odd number. The follower gear 140 at the starting end in the speed-changing gear set meshes with the first gear ring 111, and the pre-impregnation unit 130 is disposed on the follower gear 140 at the ending end in the speed-changing gear set.

[0061] Specifically, when one follower gear 140 is provided, if the rotating ring 120 rotates clockwise around the pipe pile 200, at this time, the self-rotation direction of the follower gear 140 is counterclockwise, and further drives the pre-impregnation unit 130 on the follower gear 140 to rotate counterclockwise as well, so that the pre-impregnation unit 130 maintains a constant-angle posture.

[0062] When three follower gears 140 are provided, if the rotating ring 120 rotates clockwise around the pipe pile 200, at this time, the self-rotation direction of the follower gear 140 at the starting end meshing with the first gear ring 111 is counterclockwise, the self-rotation direction of the middle follower gear 140 is clockwise, and the self-rotation direction of the follower gear 140 at the ending end is counterclockwise, and drives the pre-impregnation unit 130 disposed thereon to rotate counterclockwise, so that the pre-impregnation unit 130 maintains a constant-angle posture.

[0063] That is to say, setting the number of follower gears 140 in the speed-changing gear set to an odd number is to ensure that when the pre-impregnation unit 130 has a clockwise or counterclockwise self-rotation tendency, the rotation direction of the follower gear 140 at the most ending end in the speed-changing gear set is opposite to the rotation direction of the rotating ring 120, and further drives the pre-impregnation unit 130 to rotate in the reverse direction, so that it is in a constant-angle state.

[0064] In some other embodiments, an angle-holding unit is further included, which includes:

[0065] A cage rotatably disposed on the rotating ring 120, and the pre-impregnation unit 130 is disposed on the cage;

[0066] A first driving motor for driving the cage and the pre-impregnation unit 130 to rotate self in a second direction.

[0067] Specifically, the angle maintaining unit can also drive the pre-impregnation unit 130 to rotate itself through the first driving motor, so as to keep a posture with a constant angle. At the same time, in order to control the speed of the first driving motor to drive the pre-impregnation unit 130 to rotate reversely according to the rotation speed of the swivel ring 120, so that it is in a posture with a constant angle, the control module can be used to control the rotation speed and rotation direction of the first driving motor. For example, a sensor can be set to collect the angular velocity of the swivel ring 120 and send a signal to the control module. The control module calculates the reverse rotation speed required for the pre-impregnation unit 130 to maintain a constant angle posture according to the angular velocity of the swivel ring 120, and the control module controls the first driving motor to drive the pre-impregnation unit 130 to rotate according to the calculated rotation speed of the pre-impregnation unit 130.

[0068] Please refer to Figure 3 and Figure 4 , in this embodiment, the pre-impregnation unit 130 includes a guide member 133. The guide member 133 has a guide port, and the fiber 500 can pass through the guide member 133 and be drawn to the pipe pile 200 through the guide port;

[0069] The length direction of the fiber 500 between the guide port and the pipe pile 200 is the winding direction. The projection of the guide member 133 along the winding direction is the first projection, and the projection of the fiber 500 between the guide port and the pipe pile 200 along the winding direction is the second projection. The second projection is on the outer edge of the first projection.

[0070] Specifically, the unwound fiber 500 is drawn to the pipe pile 200 through the guide port of the guide member 133. In order to prevent the fiber 500 from winding around the guide member 133, in this embodiment, the second projection is on the edge of the first projection, so that the fiber 500 can cross over the guide member 133 and wind around the pipe pile 200 without winding around the guide member 133. Among them, the second projection is the projection of the fiber 500 between the guide port and the pipe pile 200 along its own length direction. This projection forms an image of the cross-section of the fiber, and this cross-section is on the outer edge of the second projection, which can enable the fiber not to pass through the area of the guide member corresponding to the first projection during winding, and then cross over the guide member and wind smoothly on the pipe pile.

[0071] Furthermore, a guide channel allowing the fiber 500 to pass through is provided in the guide member 133. The guide channel can be set as a channel with a constant orientation, or set as a channel formed by multiple channels with different orientations and communicating with each other, or set as a channel that is bent as a whole.

[0072] Please refer to Figure 3, the orientation of the guide member 133 is set to be parallel to the longitudinal direction of the pipe pile 200, or inclined along the longitudinal direction of the pipe pile 200 towards or away from the pipe pile 200. Among them, when the guide member 133 rotates one circle following the rotating ring 120, the fiber 500 also winds around the pipe pile 200 for one circle. At this time, the unwound fiber 500 twists one circle, but can cross over the guide member 133 to prevent the fiber 500 from winding around the guide member 133. At the same time, the fiber 500 wound around the pipe pile 200 is filamentous (although the fiber 500 in Figure 1 is sheet-like as shown for the purpose of more clearly observing the position of the fiber 500, and no limitation is imposed on the shape of the fiber 500). The filamentous fiber 500 winds around the pipe pile 200 after being twisted. The twisting causes the stress of the fiber 500 to disperse axially and circumferentially when stressed, reducing local stress concentration, enhancing its ability to resist impact and soil friction, and can also form a spiral structure during torsional deformation to achieve elastic energy storage and release, absorb more dynamic energy, and enhance seismic or impact performance.

[0073] Of course, in order to prevent the fiber 500 from twisting excessively, the size of the guide channel in the guide member 133 for the fiber 500 to pass through can be set to be slightly larger than the size of the fiber 500, so that the twisting of the fiber 500 can be transmitted to the fiber 500 on the pre-impregnation tank 132 and the fiber storage rack 131 through the guide channel, and then the twisting of the fiber 500 can be dispersed over a larger range.

[0074] Furthermore, the angle of the guide member 133 is adjustable. For example, the guide member 133 has a connection end and an outlet end that are opposite to each other. The fiber 500 extends into the guide member 133 from the connection end or the side and extends out from the outlet end. The connection end is hinged to the pre-impregnation tank 132 or other supporting components. The guide member 133 rotates around the connection end as the axis, so that the outlet direction of the outlet end can be adjusted, and further the angle between the fiber 500 and the surface of the pipe pile 200 during winding can be adjusted.

[0075] In this embodiment, the pre-impregnation unit 130 further includes a fiber storage rack 131 for storing the fiber 500 and a pre-impregnation tank 132 for containing the pre-impregnation liquid;

[0076] The upper end of the pre-impregnation tank 132 has an opening, and a cover plate is provided at the opening. The cover plate has an inlet and an outlet. The fiber 500 on the fiber storage rack 131 can penetrate into the pre-impregnation tank 132 through the inlet and penetrate out of the pre-impregnation tank 132 through the outlet.

[0077] Specifically, a cover plate is provided at the opening, and an inlet and an outlet are provided at the cover plate for the fiber 500 to penetrate into and out of, so as to block the opening to the greatest extent and prevent the pre-impregnation liquid from sloshing and overflowing during the process of the pre-impregnation tank 132 rotating around the pipe pile 200. At the same time, the cover plate can be flipped or removed to open the opening for facilitating the addition of the pre-impregnation liquid.

[0078] In this embodiment, the impregnation unit 130 includes a fiber storage rack 131 for storing fibers 500, an impregnation tank 132 for containing the impregnating liquid, and a guiding member 133.

[0079] The fiber winding mechanism 100 further includes a second driving motor for driving the rotating ring 120 to rotate, so as to pull the fibers 500 on the fiber storage rack 131 through the impregnation tank 132 and the guiding member 133 in sequence and wind them around the pipe pile 200.

[0080] Specifically, the second driving motor is arranged on the rotating ring 120, and a second gear ring 121 is arranged on the fixed ring 110. A gear meshing with the second gear ring 121 is arranged on the output shaft of the second driving motor. When the gear rotates, it can drive the rotating ring 120 to rotate relative to the fixed ring 110; or the second driving motor is arranged on the fixed ring 110, and a second gear ring 121 is arranged on the rotating ring 120. A gear meshing with the second gear ring 121 is arranged on the output shaft of the second driving motor. When the gear rotates, it can drive the rotating ring 120 to rotate relative to the fixed ring 110.

[0081] Importantly, the second driving motor can also pull out the fibers 500 from the fiber storage rack 131, pass them through the impregnation tank 132 and the guiding member 133 in sequence, and then wind them around the pipe pile 200, so as to realize the synchronous progress of impregnation and winding. When the winding speed changes or the winding is paused, the impregnation speed of the fibers 500 also changes or stops accordingly. At the same time, the power source for pulling the fibers 500 for impregnation can also be saved.

[0082] Please refer to Figure 2 , in this embodiment, a plurality of impregnation units 130 are arranged on the rotating ring 120, and the plurality of impregnation units 130 are evenly distributed along the circumferential direction of the winding hole.

[0083] Please refer to Figure 1 , this embodiment also discloses a manufacturing device for a composite pile, which includes at least one fiber winding mechanism 100, and further includes a supporting mechanism for supporting the pipe pile 200. The supporting mechanism includes a first support frame 400 and a second support frame 410 respectively located on opposite sides of the fiber winding mechanism 100.

[0084] The minimum distance from the first support frame 400 to the second support frame 410 is greater than the distance from the center of gravity of the pipe pile 200 to any one of its ends; and / or, both the first support frame 400 and the second support frame 410 are provided with conveyor belts and / or conveyor rollers for driving the pipe pile 200 to pass through the winding hole along the direction from the first support frame 400 to the second support frame 410; and / or, the manufacturing device further includes a curing device. The curing device is arranged between the second support frame 410 and the fiber winding mechanism 100. The curing device includes a heating element and / or a lighting element for curing the impregnating liquid adhered to the fibers 500; the curing device is provided with a curing hole allowing the pipe pile 200 to pass through, and the curing hole is coaxially arranged with the winding hole.

[0085] This embodiment is designed for large pipe piles 200, whose length is usually more than ten meters and the quality is relatively large, so it is impossible to transport the pipe piles 200 by clamping. Based on this, this embodiment supports the pipe piles 200 through the first support frame 400 and the second support frame 410, and the first support frame 400 and the second support frame 410 are respectively arranged on both sides of the fiber winding mechanism 100. Specifically, before winding, the pipe pile 200 is transported to the first support frame 400 by means of a lifting device or the like, and the pipe pile 200 is driven to move along its length direction by a conveyor belt and / or conveyor rollers. The front end of the pipe pile 200 gradually extends out of the first support frame 400 and extends into the winding hole. At this time, the swivel 120 of the fiber winding mechanism 100 starts to rotate and winds the fiber 500 around the pipe pile 200; as the pipe pile 200 moves step by step and the fiber winding mechanism 100 winds synchronously, the front end of the pipe pile 200 reaches the second support frame 410. At this time, the end section of the pipe pile 200 has not yet separated from the first support frame 400, and the first support frame 400 and the second support frame 410 support the pipe pile 200 at the same time; when the end section of the pipe pile 200 separates from the first support frame 400, the second support frame 410 can independently support the pipe pile 200.

[0086] Among them, the distances from the center of gravity of the pipe pile 200 to both ends are greater than the minimum distance between the first support frame 400 and the second support frame 410, so that before the center of gravity position of the pipe pile 200 separates from the first support frame 400, the second support frame 410 has already supported the pipe pile 200; before the pipe pile 200 separates from the first support frame 400, the center of gravity position of the pipe pile 200 has been supported by the second support frame 410; when the center of gravity position of the pipe pile 200 is suspended, the first support frame 400 and the second support frame 410 support the pipe pile 200 at the same time. In this way, it is avoided that the pipe pile 200 falls from the first support frame 400 or the second support frame 410, and then the clamping mechanism is replaced by this support mechanism, solving the problem that the pipe pile 200 cannot be clamped due to its excessive length and mass.

[0087] In this embodiment, the light-emitting component in the curing device is a lighting device that can emit ultraviolet light (UV) or electron beam (EB). The ultraviolet light (UV) or electron beam (EB) triggers the photosensitizer to generate free radicals or cations, causing the prepreg such as resin to polymerize. The heating component includes a heating wire or a heating sheet, and the chemical reaction between the resin and the curing agent is triggered by heating.

[0088] Specifically, the pipe pile 200 sequentially passes through the winding hole and the curing hole during the movement process. The wound fiber 500 can be timely covered by the light-emitting component and / or the heating component in the curing hole to cure the prepreg attached to the fiber 500, and then the fiber 500 is bonded to the outer surface of the pipe pile 200, forming a fiber 500 protection layer on the surface of the pipe pile 200, which plays the functions of anti-impact, anti-corrosion and anti-soil friction.

[0089] Further, a detection mechanism 300 is also provided between the curing device and the second support frame 410 to check whether the fiber 500 is fully laid on the pipe pile 200 after curing, and whether there are bubbles after the prepreg is cured. Among them, the detection mechanism 300 can implement detection by means of visual detection. For example, the distribution of the fiber 500 bundles is scanned in real time through a high-resolution camera or a laser profiler, and the image processing algorithm (such as edge detection, morphological analysis) is combined to judge whether the fiber 500 evenly covers the target area. Of course, detection can also be implemented by technical means such as acoustic wave detection, ray scanning detection, and pressure detection.

[0090] Furthermore, a sensor (such as a distance sensor, etc.) is arranged at the position of the curing device to detect the position of the pipe pile 200. When the front end of the pipe pile 200 reaches the sensor, the curing device is automatically turned on; when the pipe pile 200 leaves, the curing device is automatically turned off. Of course, in order to turn on the curing device in advance before the pipe pile 200 penetrates into the curing hole so that the curing device can have time to reach the best curing state, the sensor can also be arranged at a certain distance from the curing hole. When the pipe pile 200 has not penetrated into the curing hole, the sensor can detect the position of the pipe pile 200 to turn on the curing device in advance.

[0091] The composite pile in this embodiment is applied to fields such as ocean engineering, and the composite pile is required to have the ability to resist seawater corrosion, seawater impact, and soil friction. Based on this, the composite pile includes a centrifugally formed concrete pipe pile 200 and a fiber 500 protective layer wound around the outer peripheral surface of the pipe pile 200. Among them, the fiber 500 is glass fiber 500, carbon fiber 500, basalt fiber 500, etc., and the prepreg soaked by the fiber 500 before winding is epoxy resin, vinyl resin, unsaturated resin, polyurethane, etc. The pipe pile 200 is cylindrical, cuboid or other shapes.

[0092] It should be particularly emphasized that the composite pile in this case winds the fiber 500 on the outer surface of the already formed pipe pile 200, and the fiber 500 is on the outermost side to play a role in protecting the pipe pile 200, which is essentially different from the scheme of winding the fiber 500 around the mold and then pouring concrete to form. For example, in the scheme of winding first and then pouring to form, the fiber 500 is inside the pipe pile 200 after forming to play a role in enhancing the strength of the pipe pile 200, and the fiber 500 cannot be on the outermost side of the pipe pile 200 to play a protective role.

[0093] The above has described the embodiments of the present invention in detail with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
