Description

Technical Field

[0001] The present invention relates to the technical field of pile driving and positioning in bridge engineering, and in particular to a steel pipe pile driving and positioning frame and a positioning method thereof. Background Art

[0002] During the construction of bridge projects, the fishing method is generally used for steel pipe pile construction. The fishing method generally includes the following contents during the construction process: leveling the site, construction preparation, and advancing the construction from the end of the bridge to the head end; constructing the first span of steel pipe piles, pier caps and steel cap beams (including support pads, etc.) and the tail platform, and then constructing the main body of the bridge; using the first span as the construction platform, constructing the steel pipe piles and steel cap beams (including supports, etc.) of the next span, and then carrying out the corresponding main body of the bridge in sequence.

[0003] When the fishing method is used for steel pipe pile construction, the steel pipe pile is operated in water. The current positioning frame is generally a steel structure body, which is placed in water by hoisting and part of the body is exposed to facilitate the lowering of the steel pipe pile.

[0004] In the prior art, a pile gripper is also used to position the steel pipe pile, so that the steel pipe pile can have a stable positioning effect on the positioning frame.

[0005] The conventional steel pipe pile positioning construction process typically involves a series of meticulous steps. First, specialized measuring instruments are used to precisely determine the pile centerline, which is fundamental to ensuring the stability and accuracy of the entire structure. Subsequently, the steel pipe pile is steadily lowered to the designated location using lifting equipment. Next, measuring tools are used to meticulously inspect the center deviation and inclination of the steel pipe pile. Any deviation is immediately adjusted until all parameters meet design requirements. This process requires a high degree of precision and expertise, as even the slightest deviation can significantly impact subsequent construction and the overall structural safety.

[0006] However, in actual operation, despite the most accurate preliminary measurements, minor deviations may still be found after the steel pipe piles are in place. In this situation, the method commonly used on construction sites is to start a pile driver and use it to fine-tune the position of the pile driver. However, due to the large size of the pile driver and the limited operating space, such fine-tuning is often difficult. Not only is the operation complicated, but it is also inefficient. Sometimes, the final positioning accuracy of the steel pipe pile may even be affected due to inadequate fine-tuning. Therefore, how to improve the efficiency and accuracy of fine-tuning while ensuring safety has become an important issue that needs to be addressed in the current steel pipe pile positioning construction. Based on this, it is necessary to study a steel pipe pile sinking positioning frame and its positioning method. Summary of the Invention

In view of the problem that the current positioning frame has a simple structure and cannot perform buffering positioning of steel pipe piles and correction and detection during the lifting process, this embodiment provides a steel pipe pile sinking positioning frame, which realizes precise positioning and flexible correction of steel pipe piles by configuring leveling, positioning, detection and correction components.

[0056] In specific structures, such as Figure 1 As shown in the figure, a steel pipe pile sinking positioning frame includes a frame 1, a positioning component 4, a correction component 5, a detection component 6 and a leveling component 3.

[0057] The positioning assembly 4 includes a positioning sleeve 42, a positioning rod 43, a locking wire, a push rod 44, a spring 46 and a push wheel 45; the positioning sleeves 42 are distributed on the frame 1 and are evenly distributed on the circumference of the pile sinking space; in a specific embodiment, a center seat 41 is provided at the center of the frame 1, and the center seat 41 is fixed to the frame 1 via a connecting rod. The center seat 41 is a square structure, and the square structure facilitates the arrangement of the positioning sleeves 42. There are four positioning sleeves 42, which are respectively distributed in the middle of the four sides of the center seat, and any positioning sleeve 42 faces the center of the center seat 41. Of course, during implementation, the center seat can also be configured as other equilateral polygonal structures, such as a regular triangle, hexagon, etc., and the positioning assembly 4 is correspondingly configured on each side of the center seat.

[0058] Structurally, in order to achieve the positioning spacing adjustment of the positioning assembly 4, the positioning rod 43 is inserted into the positioning sleeve 42 and can be locked with a lock wire 49, thereby achieving free adjustment of the positioning end support spacing; the top rod 44 is arranged in the positioning rod via a spring 46, so that the top rod 44 is adjustable relative to the positioning rod 43; a top wheel 45 is provided at the end of the top rod 44, and the top wheel 45 is used to adapt and fit with the steel pipe pile 7, and provide support and positioning in a sliding fit manner on the contact surface, thereby forming an adjustable elastic positioning surface of the steel pipe pile 7 on the periphery of the pile driving space.

[0059] In specific structures such as Figure 6 As shown in the figure, the positioning rod 43 is mounted in the positioning sleeve 42, and the push rod 44 is mounted in the positioning rod 43, that is, a buffer inner cavity is provided at the front end of the positioning rod 43, and a spring seat 47 is provided on the push rod 44. The spring 46 is mounted on the push rod 44 and is in the buffer inner cavity. The outer end is limited by the spring seat 47. By mounting an end cap 48 on the outer end of the push rod 44 and threading the end cap 48 on the push rod 44, the elastic telescopic function of the push rod 44 is realized. Through two-stage adjustment, the positioning component 4 can adapt to different outer diameters of the steel pipe pile 7, which can not only provide a certain positioning strength for the steel pipe pile 7, but also adapt to the posture of the steel pipe pile 7.

[0060] like Figure 7 In the structure shown in the figure, the correction component 5 includes a sleeve 55, a correction seat 54, an upper adjusting rod 51 and a lower adjusting rod 52. The ends of the upper adjusting rod 51 and the lower adjusting rod 52 are hinged on two opposite sides of the frame 1. The upper adjusting rod 51 and the lower adjusting rod 52 are both telescopically adjustable and can be locked. They are configured to be tilted upward and downward respectively. During implementation, the upper adjusting rod 51 and the lower adjusting rod 52 can be electric telescopic rods. The electric telescopic rods can be equipped with waterproof properties and can be used for underwater applications.

[0061] The correcting seat 54 is hinged to the other end of the upper adjusting rod 51 and the lower adjusting rod 52, and the clamping sleeve 55 is arranged on the correcting seat 54. The clamping sleeves 55 on both sides are combined to form an adjustable clamping structure that can support the steel pipe pile 7 from both sides; during implementation, one side of the correcting seat 54 is connected to the clamping sleeve 55, and the specific connection method can be a fixed combination of the clamping sleeve 55 connection or an integral fixed connection. The other side of the correcting seat 54 is provided with an articulated seat 53 at the top and bottom, and the upper adjusting rod 51 and the lower adjusting rod 52 are hinged to the upper and lower articulated seats 53 respectively, and the ends of the upper adjusting rod 51 and the lower adjusting rod 52 are hinged to the mounting sleeve 56, and the mounting sleeve 56 is fixed on the frame 1, that is, the upper adjusting rod 51 and the lower adjusting rod 52 are both hinged structures at both ends, and the angle of the correcting seat 54 is adjusted when extended or shortened.

[0062] The detection assembly 6 includes a fixed seat 61, a ball seat 62, a sphere 64, a detection rod 65 and a distance sensor 66; the fixed seat 61 is fixed to the side of the frame 1, the ball seat 62 is fixed to the end of the fixed seat 61, the sphere 64 is hinged in the ball seat 62 and can be locked by a top screw 63 on the side, the detection rod 65 is fixed to the lower part of the sphere 64, and a distance sensor 66 is provided on its side, and the distance sensor 66 faces the center of the pile sinking space, that is, towards the pile sinking center line 9. In this embodiment, the detection rod 65 is further adjusted for verticality on the basis of the frame 1. By utilizing the multi-directional adjustment of the sphere 64, a hanging hammer can be configured at the lower part of the detection rod 65, and the verticality can be adjusted by its own weight. After the fixing is completed, the sphere 64 is locked from the side by the top screw, so that the vertical detection rod 65 can be further configured on the basis of the frame 1, ensuring the accuracy of the detection data and further correcting the verticality of the frame 1.

[0063] In this embodiment, when the structure is leveled, a leg 2 is provided at the lower part of the frame 1, a leveling assembly 3 is provided at the bottom of the leg 2, and a reinforcement rod 21 is provided between the legs. The legs 2 are provided with multiple groups, such as Figure 1 As shown in the structure, this embodiment is provided with 3 groups, which extend downward to support the frame 1 and extend it.

[0064] The leveling assembly 3 includes a leveling seat 31, an oil cylinder 32, a lifting seat 35 and a lifting block 33; there is a lifting chamber inside the leveling seat 31, and a oil cylinder 32 is provided in the middle of the lifting chamber. The lifting block 33 is adapted to be mounted in the lifting chamber and extends outward. A lifting seat 35 is fixed at the bottom of the lifting block 33, and the lifting seat 35 is adapted to be mounted on the outside of the leveling seat 31.

[0065] In this embodiment, a leveling seat 31 is configured at the bottom of the support leg 2. There is an inner cavity in the leveling seat 31, and there is a circular outlet at the lower part of the lifting cavity. The circular outlet is smaller than the inner cavity, and the lifting block 33 is in a sealed state in the lifting cavity, similar to a piston structure. A driving block 34 is provided at the bottom of the lifting block 33, and the driving block 34 is adapted to be assembled in the circular outlet and fixedly connected to the lifting seat. The oil cylinder 32 is used to push and pull, so that the lifting seat 35 is lifted and lowered along the leveling seat 31, so that the height of the four corners and the middle area of ​​the frame 1 can be adjusted to achieve the vertical adjustment of the frame 1, and the position adjustment of the frame 1 can be assisted by external equipment such as a spirit level, coordinate point detection, etc.

[0066] The frame 1 is provided with a water tank, which is connected to a water filling and drainage structure. The water tank is connected to a water pump, which can extract and discharge the water in the water tank. That is, during the adjustment stage, the buoyancy of the water tank can appropriately reduce the weight of the frame 1, which is convenient for position adjustment. After the adjustment is completed, the water tank is used to increase the weight to ensure its stability. During the lifting stage, the water is discharged to reduce the weight, which is convenient for the lifting operation of the frame 1.

[0067] In a specific implementation, the clamping sleeve 55 is a conical structure, and the clamping sleeves 55 on both sides form a clamping structure arranged on both sides of the steel pipe pile 7.

[0068] During implementation, this embodiment can utilize the ferrule 55 structure to use different sizes of steel pipe piles 7. Since the structure is large at the outer end and small at the inner end, combined with the square center frame and the positioning assembly 4 configured thereon, this embodiment can adapt to the position offset of the steel pipe pile 7 to a certain extent. Since the upper adjustment rod 51 and the lower adjustment rod 52 are in the plane passing through the center of the pile and are in a fixed state, during movement adjustment, they can use their inclined surfaces to perform a certain degree of position correction.

[0069] This embodiment also provides a positioning method for a steel pipe pile sinking positioning frame, which is applied to the above-mentioned steel pipe pile 7 sinking positioning frame, comprising the following steps:

[0070] Step 1: Pile sinking

[0074] Step 3: Secure the positioning frame

[0075] Fill the water tank with water to increase the weight of the positioning frame;

[0076] Step 4: Piling

[0077] Use a crane to lower the steel pipe pile 7 so that it passes through the pile sinking space of the positioning frame;

[0078] Step 5: Detection

[0079] Further adjust the verticality of the detection assembly 6 to ensure that the detection rod 65 is in a vertical state, and use two sets of distance measuring sensors 66 spaced apart on the detection rod 65 to obtain the distance between it and the surface of the steel pipe pile 7, analyze the verticality of the steel pipe pile 7, and generate a correction plan;

[0080] Step 6: Correction

[0081] Extend or shorten the upper adjusting rod 51 and the lower adjusting rod 52 to make the clamping sleeve 55 close to the steel pipe pile 7 from both sides, and then synchronously operate the upper adjusting rod 51 and the lower adjusting rod 52 on both sides to adjust the posture of the steel pipe pile in the clamping state;

[0082] Step 7: Secure positioning

[0083] Operate the positioning rod 43 to slide in the positioning sleeve 42 so that the top wheel 45 rests against the surface of the steel pipe pile 7, and then lock the positioning rod 43;

[0084] Step 8: Continuous monitoring and correction

[0085] The distance measuring sensor 66 is used to continuously monitor the posture of the steel pipe pile 7, and the posture information of the steel pipe pile 7 is fed back to the controller, and the controller generates an adjustment strategy based on the posture information.

[0086] This embodiment provides a fully functional steel pipe pile sinking positioning frame and a positioning method thereof, which realizes precise positioning and flexible deviation correction of the steel pipe pile 7 by integrating the leveling, positioning, detection and deviation correction components 5. The positioning frame adopts a frame structure and is provided with multiple pile sinking spaces, which can simultaneously position multiple steel pipe piles 7. The positioning component 4 adapts to the different outer diameters of the steel pipe piles 7 through two-stage adjustment and provides elastic support. The deviation correction component 5 uses an electric telescopic rod and an adjustable clamping structure to achieve precise adjustment of the posture of the steel pipe pile 7. The detection component 6 ensures the verticality of the positioning frame and the steel pipe pile 7 through a vertical detection rod 65 and a distance sensor 66. In addition, the positioning frame is also equipped with a leveling component 3 and a water tank to adjust the level of the frame 1 and increase stability. The positioning method has clear steps, from pile sinking to continuous monitoring and deviation correction, which ensures the accurate positioning and posture adjustment of the steel pipe pile 7.

[0089] There are two groups of correcting components 5, one above and one below, distributed on the left and right sides and the front and back sides of the frame 1 . There are two groups of detecting components 6, which are arranged corresponding to the correcting components 5 .

[0090] During implementation, the positioning component 4 can stabilize the steel pipe pile 7 from the top and bottom.

At the same time, the correction component 5 and the detection component 6 are configured from four directions, so that they can be adjusted synchronously from the front and back directions and the left and right directions, ensuring the verticality of the steel pipe pile 7.
