Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, and in particular to a pile clamping structure. Background Technology

[0002] In the construction of offshore wharves, driving steel pipe piles is a common project. The conventional procedure involves first dredging or clearing the seabed to ensure the steel pipe piles can be driven to the designed depth; then, guide frames or positioning equipment are used to ensure the verticality and accurate positioning of the piles; next, the piles are driven into the seabed surface by their own weight or with light hammering, and then gradually driven to the designed depth using a diesel hammer or hydraulic hammer, while monitoring penetration and verticality. Once the piles have been driven to the designed depth and their verticality, penetration, and bearing capacity are confirmed to meet requirements, the pile caps are installed. However, when the wharf's pile foundation is located primarily on existing land, a reverse construction method, known as "water-to-land" construction, can be adopted for high-pile wharves. This method changes the traditional offshore pile driving process, allowing for pile driving and pile cap pouring on land first, followed by excavator and dredging vessel cleaning between the piles and excavation of the revetment. This reverse construction method avoids the disadvantages of low efficiency and high cost associated with offshore pile driving.

[0003] However, when using this reverse construction method, after the steel pipe piles are driven into the ground and the pile caps are poured, it is necessary to carry out mud cleaning between the piles. During the mud cleaning process, the steel pipe piles may be displaced due to excessive mud cleaning speed, requiring the use of pile clamps. Existing pile clamps, such as the new simplified pile clamping structure disclosed in Chinese Utility Model Patent No. CN222541466U, or the steel pipe pile clamping structure disclosed in Chinese Utility Model Patent No. CN220246920U, are all installed on the main body of the steel pipe pile, which will interfere with the subsequent mud cleaning operation between the piles, making it impossible for excavators and dredgers to enter the area between the piles for mud cleaning. Therefore, they are not suitable for the above-mentioned reverse construction method of pile foundation. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing pile clamping structures, which are all fixed to the main body of steel pipe piles, greatly interfering with the subsequent mud cleaning operation between piles and unable to adapt to the reverse construction method of pile foundation, and to provide a pile clamping structure.

[0005] In a first aspect, the present invention provides a pile clamping structure, comprising a plurality of steel pipe piles, wherein a pile cap is provided on the top of the steel pipe piles, and a fixing frame is also provided, wherein the fixing frame is located on the top surface of the pile cap, and a plurality of clamping components are fixedly connected to the fixing frame, wherein adjacent clamping components are arranged in a mirror image, and the clamping components are used to clamp the pile cap.

[0006] Traditional pile clamping structures are mostly fixed to the main body of steel pipe piles, which often occupies the working space between piles and affects the access of excavators and dredgers to the pile-between area for dredging operations. However, the pile clamping structure provided by this utility model has its fixing frame installed on the top surface of the pile cap, so that the clamping components only act on the pile cap area and do not extend into the pile-between area. This ensures that dredging machinery has sufficient passage space during operation, significantly improving the efficiency and safety of subsequent dredging operations.

[0007] The pile clamping structure provided by this utility model has a fixing frame that clamps the pile cap from the top surface. The mirror-arranged clamping components ensure a balanced distribution of clamping force on the pile cap. This symmetrical design can effectively prevent the eccentric force effect caused by unilateral force. After the silt between the piles is cleared, the steel pipe pile can still maintain stability and prevent the pile from tilting or shifting due to uneven force.

[0008] Preferably, the clamping component includes: at least two uprights, one end of which is fixedly connected to the fixing frame, the other end of which is connected to a diagonal brace, the end of which is away from the uprights and is fixedly connected to the fixing frame, and the uprights are connected to the side wall of the pile cap through a fixing component.

[0009] With this structural setup, one end of the upright is fixed to the fixing frame, and the other end is firmly connected to the side wall of the pile cap through fixing components, ensuring that the steel pipe pile is not easily displaced or deformed when the lateral force changes, thereby maintaining the overall stability of the steel pipe pile.

[0010] The connection between the upright and the diagonal brace forms an oblique load-bearing system. One end of the diagonal brace is connected to the upright, and the other end is fixed to the support frame, forming a triangular load-bearing structure. This design can quickly transfer lateral loads to the support frame through the triangular structure, significantly improving the overall structure's resistance to lateral forces and preventing displacement of the steel pipe piles due to changes in the lateral forces during excavator and dredger operations.

[0011] Preferably, the angle between the diagonal brace and the upright is 40° to 50°.

[0012] The angle between the diagonal brace and the upright is set at 40°~50°. Within this angle range, the triangular support structure formed by the diagonal brace and the upright can more effectively decompose the external force into forces along the direction of the members, thereby evenly transferring the load to the fixed frame and ensuring that the overall structure is reasonably stressed and stable.

[0013] Preferably, the clamping component further includes at least three crossbars, with the two ends of adjacent uprights connected by the crossbars, and the end of adjacent diagonal braces connected to the fixing frame also connected by the crossbars.

[0014] By adding at least three crossbars to the clamping components, these crossbars act as lateral reinforcement members, preventing torsion and deformation throughout the structure. By firmly connecting the components to form a stable, rigid frame, the clamping components effectively resist structural deformation caused by external loads, ensuring that the pile caps and steel pipe piles do not experience adverse displacement or tilting during mud removal operations.

[0015] Preferably, the fixing component includes a bolt, a nut, and a washer. The bolt head abuts against the side wall of the pile cap, the bolt shank is threaded to the upright, the nut is threaded to the shank, the nut is located between the bolt head and the upright, and a washer is provided between the nut and the upright.

[0016] The bolt head directly abuts against the side wall of the pile cap, ensuring stable mechanical support between the pile cap and the upright. A washer is placed between the nut and the upright to distribute the pressure applied when tightening the nut evenly over a large contact area, avoiding localized damage or fatigue of the material due to excessive local pressure. By adjusting the nut, the distance between the pile cap and the upright can be precisely controlled, ensuring sufficient fixation of the clamping components.

[0017] Preferably, the fixing frame includes at least two longitudinal beams, and several crossbeams are fixedly connected between the longitudinal beams.

[0018] The longitudinal beams, as the main load-bearing components, provide the overall skeleton for the fixing frame, while the crossbeams, acting as reinforcements and connections between the two longitudinal beams, form a complete and stable frame. This frame structure effectively prevents local deformation and ensures the stability of the entire pile-clamped structure under external loads.

[0019] Preferably, the fixing frame further includes several reinforcing ribs, which are obliquely intersecting the longitudinal beam.

[0020] The reinforcing ribs are arranged obliquely to the longitudinal beams, and adjacent reinforcing ribs also intersect each other obliquely, forming a triangular support network subjected to multi-directional forces. This triangular support system can significantly improve the overall rigidity of the frame, enabling it to remain stable under lateral forces, vibrations, or torsional loads, preventing structural deformation or loosening.

[0021] Preferably, it further includes a pad located between the fixing frame and the top surface of the pile cap.

[0022] Since there may be slight unevenness or installation errors on the top surface of the pile cap during actual construction, the pads can play an adjustment role to ensure that the fixing frame is level, thereby improving the installation accuracy and stability of the entire structure. On the other hand, as a buffer layer, the pads can absorb the impact and vibration generated during construction, reduce the impact force when the fixing frame acts directly on the pile cap, prevent damage to the surface of the pile cap, and protect the overall stability of the steel pipe pile.

[0023] Preferably, it also includes an operation panel, which is laid on the top surface of the fixing frame.

[0024] The control panel is installed on top of the fixing frame, which not only functions to hold the pile caps but also serves as a temporary passageway on the construction site. Construction workers can pass directly through the top of the fixing frame, facilitating movement between the pile top and the construction area, avoiding detours or the construction of additional temporary passageways, and significantly improving the convenience of on-site construction.

[0025] Preferably, both the fixing frame and the clamping component are channel steel structural parts.

[0026] Channel steel itself possesses excellent strength and rigidity, enabling it to withstand significant loads and external forces. When clamping the pile cap, it can effectively resist the tilting or displacement of the steel pipe pile due to uneven stress caused by lateral force changes during the mud removal process between piles, ensuring the stability and reliable fixation of the steel pipe pile.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] 1. This utility model provides a pile clamping structure, in which the fixing frame is installed on the top surface of the pile cap, so that the clamping component only acts on the pile cap area and does not extend to the area between piles, thereby ensuring that the sludge cleaning machinery has sufficient passage space during operation, and significantly improving the efficiency and safety of subsequent sludge cleaning operations;

[0029] 2. This utility model provides a pile clamping structure, in which the fixing frame clamps the pile cap from the top surface. The mirror-arranged clamping components ensure a balanced distribution of clamping force on the pile cap. This symmetrical design can effectively prevent the eccentric force effect caused by unilateral force. After the silt between the piles is cleared, the steel pipe pile can still maintain stability and prevent the pile from tilting or shifting due to uneven force. Attached Figure Description

[0044] Example 1

[0045] This embodiment provides a clamping pile structure for auxiliary fixing of steel pipe piles after the completion of onshore piling and pile cap pouring during the "water-to-land" reverse construction of a high-pile wharf.

[0046] The pile clamping structure includes several steel pipe piles 100, with pile caps 200 installed on top of each steel pipe pile 100. Figure 1 , Figure 2 For example, Figure 1 , Figure 2 The diagram shows a configuration with seven steel pipe piles 100. The leftmost and rightmost steel pipe piles 100 share the same pile cap 200, while the three middle steel pipe piles 100 have their own independent pile caps 200.

[0047] The pile clamping structure also includes a fixing frame 1, which is located on the top surface of the pile cap 200. The fixing frame 1 is fixedly connected to several clamping components 2, and adjacent clamping components 2 are arranged in a mirror image. The clamping components 2 are used to clamp the pile cap 200.

[0048] Furthermore, in this embodiment, the fixing frame 1 includes at least two longitudinal beams 11, and several cross beams 12 are fixedly connected between the longitudinal beams 11. The fixing frame 1 also includes several reinforcing ribs 13, which are oblique to the longitudinal beams 11.

[0049] by Figure 1 , Figure 2 , Figure 3Taking this as an example, there can be two longitudinal beams 11, which are parallel to each other. Several crossbeams 12 are welded between the two longitudinal beams 11. The crossbeams 12 can be perpendicular to the longitudinal beams 11, and they are also parallel to each other. To further improve the stability of the fixing frame 11, several reinforcing ribs 13 can be set between the longitudinal beams 11. The reinforcing ribs 13 are oblique to the longitudinal beams 11 and also oblique to the crossbeams 12. Furthermore, two reinforcing ribs 13 can be set as a group, and within the same group, the two reinforcing ribs 13 are fixedly connected to the crossbeams 12 at the same point.

[0050] In this structural configuration, the longitudinal beams 11 serve as the main load-bearing components, providing an overall skeleton for the fixing frame 1. The transverse beams 12, acting as reinforcement and connection between the two longitudinal beams 11, form a complete and stable frame. This frame structure effectively prevents local deformation, ensuring the stability of the entire pile-clamped structure under external loads. The reinforcing ribs 13 are arranged obliquely to both the longitudinal beams 11 and the transverse beams 12, forming a multi-directional triangular support network. This triangular support system significantly improves the overall rigidity of the fixing frame 1, ensuring its stability under lateral forces, vibrations, or torsional loads, preventing structural deformation or loosening.

[0051] Furthermore, the clamping component 2 includes: at least two uprights 21, one end of each upright 21 is fixedly connected to the fixing frame 1, the other end of each upright 21 is connected to a diagonal brace 22, the end of the diagonal brace 22 away from the upright 21 is fixedly connected to the fixing frame 1, and the uprights 21 are connected to the side wall of the pile cap 200 through the fixing component. Figure 1 , Figure 3 For example, the same pile cap 200 can be clamped by two clamping parts 2 arranged in a mirror image to ensure that when the steel pipe pile 100 is subjected to uneven lateral force, the force can be smoothly transmitted to the fixing frame 1 located on the top surface of the pile cap 200. The fixing frame 1 can play the role of assisting in fixing the steel pipe pile 100. Figure 3 The clamping component 2 includes two parallel uprights 21. The tops of the two uprights 21 are welded to two longitudinal beams 11, and the bottoms of the two uprights 21 are welded to diagonal braces 22, such as... Figure 3 As shown, the angle between the upright 21 and the diagonal brace 22 is α. In this embodiment or other embodiments, ∠α can be in the range of 40°~50°. The tops of the two diagonal braces 22 are welded to the longitudinal beam 11 respectively.

[0052] With this structural setup, one end of the upright 21 is fixed to the fixing frame 1, and the other end is firmly connected to the side wall of the pile cap 200 through the fixing component, ensuring that the steel pipe pile 100 is not easily displaced or deformed when the lateral force changes, thereby maintaining the overall stability of the steel pipe pile 100.

[0053] The connection between the upright 21 and the diagonal brace 22 forms an oblique force-bearing system. One end of the diagonal brace 22 is connected to the upright 21, and the other end is fixed to the fixing frame 1, forming a triangular force-bearing structure. This design can quickly transfer lateral loads to the fixing frame 1 through the triangular structure, significantly improving the overall structure's resistance to lateral forces and preventing displacement of the steel pipe pile 100 due to changes in the lateral force during excavator and dredger operations. Setting the included angle α between the diagonal brace 22 and the upright 21 to 40°~50°, within this angle range, the triangular support structure formed by the diagonal brace 22 and the upright 21 can more effectively decompose external forces into forces along the direction of the members, thereby uniformly transferring the load to the fixing frame 1 and ensuring reasonable and stable stress distribution of the overall structure.

[0054] Furthermore, the clamping component 2 also includes at least three crossbars 24, with the two ends of adjacent uprights 21 connected by the crossbars 24, so as to... Figure 3 For example, Figure 3 The two uprights 21 are connected to the longitudinal beam 11 via a first horizontal bar 24, and the two uprights 21 are connected to the diagonal braces 22 via a second horizontal bar 24. The ends of adjacent diagonal braces 22 that connect to the fixing frame 1 are also connected via horizontal bars 24. Figure 3 For example, the two diagonal braces 22 are connected to the longitudinal beam 11 via a third crossbar 24. By adding at least three crossbars 24 to the clamping component 2, the crossbars 24 act as lateral reinforcement members, preventing torsion and deformation in the entire structure. By firmly connecting the components, a stable rigid frame is formed, and the clamping component 2 can effectively resist structural deformation caused by external loads, ensuring that the pile cap 200 and the steel pipe pile 100 do not experience adverse displacement or tilting during the sludge removal operation.

[0055] Furthermore, such as Figure 4 As shown, the fixing components include a bolt 231, a nut 232, and a washer 233. The bolt head of the bolt 231 abuts against the side wall of the pile cap 200, and the bolt shank of the bolt 231 is threadedly connected to the upright 21. The nut 232 is threadedly connected to the bolt shank and is located between the bolt head and the upright 21. The washer 233 is placed between the nut 232 and the upright 21. The direct abutment between the bolt head of the bolt 231 and the side wall of the pile cap 200 ensures stable mechanical support between the pile cap 200 and the upright 21. The washer 233 placed between the nut 232 and the upright 21 can evenly distribute the pressure applied when the nut 232 is tightened over a large contact area, avoiding localized damage or fatigue of the material due to excessive local pressure. By adjusting the nut 232, the distance between the pile cap 200 and the upright 21 can be precisely controlled, so that the clamping component 2 achieves sufficient fixing effect.

[0056] Furthermore, in this embodiment, the fixing frame 1 and the clamping component 2 can be formed by welding channel steel commonly used in engineering construction to form a channel steel structure. The channel steel itself has excellent strength and rigidity, and can withstand large loads and external forces. When clamping the pile cap 200, it can effectively resist the lateral force changes of the steel pipe pile 100 during the mud cleaning process between piles, which may cause the pile body to tilt or shift due to uneven force, thus ensuring the stability and fixing reliability of the steel pipe pile 100.

[0057] Traditional pile clamping structures are mostly fixed to the main body of the steel pipe pile 100, which often occupies the working space between piles and affects the access of excavators and dredgers to the pile-between area for dredging operations. However, the pile clamping structure provided in this embodiment has its fixing frame 1 installed on the top surface of the pile cap 200, so that the clamping component 2 only acts on the area of ​​the pile cap 200 and does not extend into the pile-between area. This ensures that the dredging machinery has sufficient passage space during operation, significantly improving the efficiency and safety of subsequent dredging operations.

[0058] The pile clamping structure provided in this embodiment has a fixing frame 1 clamping the pile cap 200 from the top surface. The mirror-arranged clamping components 2 ensure a balanced distribution of clamping force on the pile cap 200. This symmetrical design can effectively prevent the eccentric force effect caused by unilateral force. After the silt between the piles is cleaned, the steel pipe pile 100 can still be kept stable, preventing the pile from tilting or shifting due to uneven force.

[0059] Example 2

[0060] Because slight unevenness or installation errors may exist on the top surface of the pile cap 200 during actual construction, the pile clamping structure provided in this embodiment, based on Embodiment 1, also includes a pad 3, which is located between the fixing frame 1 and the top surface of the pile cap 200. Figure 5 For example, Figure 5 The height of the left and right pile caps 200 is lower than that of the three middle pile caps 200. Therefore, pads 3 can be installed on the top surface of the left and right pile caps 200, and the fixing frame 1 can be placed on the pads 3 to ensure that the fixing frame 1 is horizontal. The pads 3 can play an adjustment role to ensure that the fixing frame 1 is horizontal, thereby improving the installation accuracy and stability of the entire structure. On the other hand, the pads 3, as a buffer layer, can absorb the impact and vibration generated during construction, reduce the impact force when the fixing frame 1 acts directly on the pile cap 200, prevent damage to the surface of the pile cap 200, and protect the overall stability of the steel pipe pile 100.

[0061] Example 3

[0062] Based on Example 2, such as Figure 6As shown, the pile clamping structure provided in this embodiment also includes an operation panel 4, which is laid on the top surface of the fixing frame 1. The operation panel 4 can be a steel plate, a wooden board, or a steel wire mesh. Laying the operation panel 4 on the top surface of the fixing frame 1 allows the fixing frame 1 to not only clamp the pile cap 200, but also serve as a temporary passage on the construction site. Construction personnel can pass directly through the top of the fixing frame 1, facilitating movement between the pile top and the construction area, avoiding detours or the construction of additional temporary passages, and significantly improving the convenience of on-site construction.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
