Description
Technical Field
[0001] The invention relates to the technical field of underwater piling, and in particular to an elastic clamp and a pile driving tool for assisting pile driving. Background Art
[0002] During underwater construction, it is often necessary to drive piles into the underwater strata as anchor points to facilitate subsequent construction work. In the prior art, two construction methods are generally used for underwater piling operations:
[0003] First, use an underwater hydraulic hammer to directly sink piles underwater. Although the underwater hydraulic hammer can drive steel sheet piles in seawater environment, long-term immersion in seawater will cause corrosion and wear of the equipment. The salt and minerals in the seawater will chemically corrode the metal parts of the hydraulic hammer, and the tiny particles and impurities in the seawater will cause physical wear on the surface of the equipment. These corrosion and wear phenomena will not only reduce the performance and stability of the equipment, but also shorten its service life. At the same time, the underwater working environment is complex, and the changes in the construction environment and the reduction in equipment stability will further increase the construction risk. These factors will increase the construction cost and construction risk of the project;
[0004] The second method is to use a conventional vibratory hammer for construction. Since a conventional vibratory hammer cannot be extended underwater, one end of the steel sheet pile needs to be extended out of the water and connected to the vibratory hammer, and then the vibratory hammer is used to sink the pile. After the vibratory hammer drives the other end of the pile into the underwater stratum, the excess pile is cut off manually through underwater cutting operations so that the length of the pile can meet the needs of subsequent construction operations. Although this method has low cost, it requires underwater cutting operations, which not only complicates the construction process but also creates greater construction risks. Summary of the invention
[0005] The purpose of the present invention is to overcome the shortcomings of the prior art that when using conventional vibratory hammers for pile driving operations, underwater cutting operations are required, which not only complicates the construction process but also generates greater construction risks, and to provide an elastic clamp and a pile driving tool for assisting pile driving.
[0006] In a first aspect, the present invention provides an elastic clamp for assisting pile driving, comprising a clamping portion, an elastic member and an adjusting member, the clamping portion comprising a first clamping member and a second clamping member, the first clamping member and / or the second clamping member being connected to the adjusting member, the clamping portion being used to clamp the contact position between the pile body and the connecting rod, the adjusting member being used to make the first clamping member and the second clamping member approach or move away from each other, the adjusting member being connected to the elastic member, and when the clamping portion is in a clamping state, the elastic member is in a compressed state.
[0007] By operating the adjusting member, the first clamping member and the second clamping member are moved away from each other, so that the pile body can be placed in the clamping part. After the pile body is placed in the clamping part, the first clamping member and the second clamping member are moved closer to each other by operating the adjusting member until the first clamping member and the second clamping member are clamped at the position where the pile body and the connecting rod are in contact. At this time, the clamping part is in a clamping state. In the clamping state, the elastic member is compressed by the adjusting member, so that the elastic member applies a pre-tightening force to the pile body through the clamping part, so that the clamping part can clamp the pile body, thereby improving the firmness of the elastic clamp to the pile body, and thus improving the reliability of the elastic clamp when in use.
[0008] The elastic clamp is clamped at the contact position between the pile body and the connecting rod, and the end of the pile body close to the connecting rod can be connected to the connecting rod, and the connecting rod can be connected to the piling equipment. The piling equipment can drive the pile body clamped by the elastic clamp into the anchoring medium by driving the connecting rod. When the pile body is driven into the anchoring medium to a preset depth, the connecting rod is lifted. Since the pile body can meet the pull-out resistance, the elastic clamp can be separated from the pile body and rises with the connecting rod, and the pile body is anchored in the anchoring medium.
[0009] The clamping portion may be a clamping block or a clamping plate, etc., the adjusting member may be a fastening bolt or a positioning pin, etc., and the elastic member may be a fastening spring or an ejector spring, etc.
[0010] With this arrangement, a conventional vibratory hammer can be used to carry out piling operations on the elastic clamp that clamps the pile body. After the piling is completed, it is only necessary to pull out the elastic clamp to separate the elastic clamp from the pile body, eliminating the step of underwater cutting operations and reducing the complexity and risk of construction.
[0011] The first clamping member and the second clamping member may be both connected to the adjusting member, or the first clamping member may be connected to the adjusting member, or the second clamping member may be connected to the adjusting member.
[0012] By setting the first clamping member to be connected to the adjusting member, or setting the second clamping member to be connected to the adjusting member, the adjusting member can drive the second clamping member to be close to or away from the first clamping member, or the adjusting member can drive the first clamping member to be close to or away from the second clamping member, so as to realize the opening or closing of the clamping part. By only changing the relative position of the second clamping member and the first clamping member, or the relative position of the first clamping member and the second clamping member, the complexity of the structure of the clamping part is reduced, thereby reducing the convenience of operating the clamping part and improving the reliability of the elastic clamp.
[0013] The first clamping member includes a clamping plate and a connecting plate, the second clamping member is located between the clamping plate and the connecting plate, the adjusting member is a bolt, the elastic member is a spring, and both the adjusting member and the elastic member pass through the connecting plate to be connected to the second clamping member.
[0014] The adjusting member and the elastic member are both connected to the second clamping member through the connecting plate, so that the second clamping member can move relative to the clamping plate while the first clamping member is immobile, which can increase the overall rigidity of the elastic clamp; at the same time, the second clamping member is arranged close to or away from the clamping plate, which simplifies the operation of the elastic clamp and improves the convenience of using the elastic clamp.
[0015] The second clamping member is a flat plate, and the contact surfaces of the second clamping member and the clamping plate with the pile body are respectively flat.
[0016] By making the contact surfaces of the second clamping member and the clamping plate with the pile body respectively flat, the contact areas of the second clamping member and the clamping plate with the pile body respectively can be increased, thereby increasing the friction between the elastic clamp and the pile body.
[0017] The pile body can also be configured as a cylinder or a prism, etc., and the contact surfaces of the first clamping member and the second clamping member with the pile body are arc surfaces or concave surfaces that can match the surface of the pile body.
[0018] The elastic clamp for assisting pile driving also includes a limiting column, which is sleeved in the spring, with an axial direction of the limiting column parallel to the axial direction of the spring, and the limiting column passes through the connecting plate and is connected to the second clamping member.
[0019] By arranging the limiting column, the ability of the spring to expand and contract along the axial direction of the limiting column is improved, and the stability of the spring during expansion and contraction is improved.
[0020] The limiting column may be coaxially arranged with the spring.
[0021] The elastic clamp for assisting pile driving also includes a connecting piece. The number of the elastic components and the number of the adjusting components are both several. The several elastic components are connected to the connecting piece, and the several adjusting components are connected to the several elastic components through the connecting piece.
[0022] By providing a plurality of elastic components and a plurality of adjusting components, the clamping force of the elastic clamp on the pile body can be improved, and the reliability of the elastic clamp can be improved; by providing a connecting piece, the connecting piece is connected to the plurality of elastic components. When the adjusting component is operated, the adjusting component can drive the plurality of elastic components to compress or extend through the connecting piece, thereby improving the ability of the plurality of elastic components to compress or extend synchronously, making the force of the elastic component applied to the clamping part more uniform, thereby improving the stability of the elastic component.
[0023] The number of the elastic components may be 2, 3, or 4, etc., and the number of the adjusting components may be 2, 3, or 4, etc.
[0024] The connecting member may be a connecting rod or a connecting plate, etc.
[0025] The clamping portion is a rectangular parallelepiped, and the plurality of elastic components and the plurality of adjusting components are arranged along a symmetric axis in the length direction of the clamping portion.
[0026] By arranging the plurality of elastic components and the plurality of adjusting components along the axis of symmetry in the length direction of the clamping portion, the ability of the clamping portion to maintain balance when subjected to force can be improved, and the tilt or deviation caused by asymmetric load can be reduced. At the same time, the elastic components and adjusting components arranged along the axis of symmetry can evenly distribute the force acting on the clamping portion, thereby improving the overall rigidity and reducing the probability of deformation.
[0027] A plurality of the elastic components and a plurality of the adjusting components are arranged alternately.
[0028] By staggering the plurality of elastic components and the plurality of adjusting components, it is helpful to more effectively transmit and disperse the force exerted by the elastic components on the clamping portion, reduce stress concentration, and reduce the probability of local deformation or damage;
[0029] The distance between two adjacent elastic components is equal, and the distance between two adjacent adjustment components is equal.
[0030] By making the distance between two adjacent elastic components equal, and the distance between two adjacent adjustment components equal, it helps to evenly distribute the stress in the elastic clamp, provide more consistent support and bending resistance, and thus improve the overall rigidity and stability.
[0031] The plurality of elastic components and the plurality of adjustment components may also be arranged arbitrarily.
[0032] In a second aspect, the present invention provides a pile driving tool, provided with a connecting rod and the elastic clamp for assisting pile driving, wherein the connecting rod is connected to the elastic clamp for assisting pile driving.
[0033] By setting a connecting rod so that the connecting rod is extended out of the water, the piling equipment transmits the force applied to the connecting rod to the pile body by striking the connecting rod, thereby driving the pile body into the underwater stratum. By setting the connecting rod, the requirements for the working environment of the piling equipment during the piling operation are reduced, and the applicability of the pile driving tool when used is improved.
[0034] The connecting rod may be detachably connected to the elastic clamp for assisting pile sinking, may be fixedly connected to the elastic clamp for assisting pile sinking, or may be integrally formed with the elastic clamp for assisting pile sinking.
[0035] Compared with the prior art, the present invention has the following beneficial effects:
[0036] 1. The present invention provides an elastic clamp for assisting pile driving, comprising a clamping portion, an elastic member and an adjusting member, wherein the clamping portion comprises a first clamping member and a second clamping member, the first clamping member and / or the second clamping member are connected to the adjusting member, the clamping portion is used to clamp the contact position between the pile body and the connecting rod, the adjusting member is used to make the first clamping member and the second clamping member approach or move away from each other, the adjusting member is connected to the elastic member, and when the clamping portion is in a clamping state, the elastic member is in a compressed state. Through this arrangement, the step of separating the clamping portion from the pile body through underwater cutting operations is omitted, reducing the complexity and risk of construction. Through this arrangement, a conventional vibrating hammer can be used to perform pile driving operations on the elastic clamp holding the pile body. After the pile driving is completed, it is only necessary to pull out the elastic clamp to separate the elastic clamp from the pile body, eliminating the step of separating the elastic clamp from the pile body through underwater cutting operations, reducing the complexity and risk of construction.

[0050] Example 1
[0051] like Figure 1-3 As shown, an elastic clamp for assisting pile driving comprises a clamping portion 2, an elastic member 41 and an adjusting member 42, wherein the clamping portion 2 comprises a first clamping member 21 and a second clamping member 22, wherein the second clamping member 22 is connected with the adjusting member 42, the clamping portion 2 is used for clamping the contact position between the pile body 3 and the connecting rod 1, the adjusting member 42 is used for making the first clamping member 21 and the second clamping member 22 approach or move away from each other, the adjusting member 42 is connected to the elastic member 41, and when the clamping portion 2 is in a clamping state, the elastic member 41 is in a compressed state.
[0052] By operating the adjusting member 42, the first clamping member 21 and the second clamping member 22 are moved away from each other, so that the pile body 3 can be placed in the clamping part 2. After the pile body 3 is placed in the clamping part 2, the first clamping member 21 and the second clamping member 22 are moved closer to each other by operating the adjusting member 42 until the first clamping member 21 and the second clamping member 22 are clamped at the position where the pile body 3 and the connecting rod 1 are in contact. At this time, the clamping part 2 is in a clamping state. In the clamping state, the elastic member 41 is compressed by the adjusting member 42, so that the elastic member 41 applies a pre-tightening force to the pile body 3 through the clamping part 2, so that the clamping part 2 can clamp the pile body 3, thereby improving the firmness of the elastic clamp to clamp the pile body 3, and thereby improving the reliability of the elastic clamp when in use.
[0053] The elastic clamp is clamped at the contact position between the pile body 3 and the connecting rod 1. The end of the pile body 3 close to the connecting rod 1 can be connected to the connecting rod 1. The connecting rod 1 can be connected to the piling equipment. The piling equipment can drive the pile body 3 clamped by the elastic clamp into the anchoring medium by injecting the connecting rod 1. When the pile body 3 is driven into the anchoring medium to a preset depth, the connecting rod 1 is lifted. Since the pile body 3 can meet the pull-out resistance, the elastic clamp can be separated from the pile body 3 and rise with the connecting rod 1, and the pile body 3 is anchored in the anchoring medium.
[0054] When the clamping part 2 clamps the pile body 3, the clamping part 2 clamping the pile body 3 is lifted until the pile body 3 is suspended in the air. At this time, the pile body 3 is subjected to its own gravity G 桩 and the clamping part 2 applies the same force as G to the pile body 3 桩 Static friction F is equal in magnitude and opposite in direction 夹静 At this time, the pile body 3 is under balanced force, that is, the clamping part 2 can lift the pile body 3 to the suspended state without the pile body 3 falling, and the maximum static friction force between the clamping part 2 and the pile body 3 is set to F 夹静max , so that F 夹静max >G 桩 , which increases the probability that the clamping part 2 can lift the pile body 3 into the air without causing the pile body 3 to separate from the clamping part 2;
[0055] When the pile body 3 is driven into the underwater stratum to a preset depth, the side wall of the pile body 3 abuts against the surrounding medium, so that part or all of the pile body 3 clamped by the clamping part 2 enters the underwater stratum, and the underwater stratum abuts against the outer wall of the pile body 3. When a force is applied to the clamping part 2 to move the clamping part 2 away from the pile body 3, the clamping part 2 tends to drive the pile body 3 to move. The static friction force F between the clamping part 2 and the pile body 3 夹静 will increase, because the pile body 3 abuts against the surrounding medium, the surrounding medium will exert a static friction force F on the pile body 3 to prevent the pile body 3 from moving. 介静 , at this time F 介静 With F 夹静 In the opposite direction, F 介静 With G 桩 The direction of F 介静 +G 桩 =F 夹静 , so that the pile body 3 remains stationary. As the force applied to the clamping part 2 gradually increases, the static friction force applied by the clamping part 2 to the pile body 3 will also become larger and larger. When the static friction force applied by the clamping part 2 to the pile body 3 reaches F 夹静max When F 介静max +G 桩 >F 夹静max At this time, the static friction force exerted by the surrounding medium on the pile body 3 is less than F 介静max , the pile body 3 still remains stationary.
[0056] Continue to increase the force applied to the clamping part 2 until the force is greater than F 夹静max , the friction between the clamping part 2 and the pile body 3 will become a sliding friction, and the sliding friction is smaller than F 夹静max At this time, a relative displacement occurs between the clamping part 2 and the pile body 3, and finally the clamping part 2 is separated from the pile body 3, while the pile body 3 is anchored in the underwater stratum.
[0057] During construction, the clamping part 2 is used to clamp the pile body 3 so that F 夹静max >G 桩 Then, the pile body 3 is driven into the underwater stratum using a pile driving tool so that the contact area between the underwater stratum and the pile body 3 reaches the construction requirements, thereby making F 介静max +G 桩 >F 夹静max Then, a force greater than F is applied to the clamping part 2. 夹静max The force causes the clamping part 2 to move away from the pile body 3, and finally the pile body 3 is anchored in the underwater stratum.
[0058] The clamping portion 2 is a clamping plate, the adjusting member 42 is a fastening bolt, and the elastic member 41 is a fastening spring.
[0059] Through this arrangement, a conventional vibratory hammer can be used to carry out piling operations on the elastic clamp holding the pile body 3. After the piling is completed, it is only necessary to pull out the elastic clamp to separate the elastic clamp from the pile body 3, eliminating the step of underwater cutting operations and reducing the complexity and risk of construction.
[0060] The adjusting member 42 can drive the second clamping member 22 to move closer to or away from the first clamping member 21, so as to realize the opening or closing of the clamping part 2. By only changing the relative position of the second clamping member 22 and the first clamping member 21, the complexity of the structure of the clamping part 2 is reduced, thereby reducing the convenience of operating the clamping part 2 and improving the reliability of the elastic clamp.
[0061] The first clamping member 21 includes a clamping plate 211 and a connecting plate 212, the second clamping member 22 is located between the clamping plate 211 and the connecting plate 212, the adjusting member 42 is a bolt, the elastic member 41 is a spring, and both the adjusting member 42 and the elastic member 41 pass through the connecting plate 212 to be connected to the second clamping member 22.
[0062] The adjusting member 42 and the elastic member 41 are both connected to the second clamping member 22 through the connecting plate, so that the second clamping member 22 can move relative to the clamping plate while the first clamping member 21 is immobile, which can increase the overall rigidity of the elastic clamp; at the same time, setting the second clamping member 22 close to or away from the clamping plate simplifies the operation of the elastic clamp and improves the convenience of using the elastic clamp.
[0063] The second clamping member 22 is a flat plate, and the contact surfaces of the second clamping member 22 and the clamping plate 211 with the pile body 3 are respectively flat surfaces.
[0064] By making the contact surfaces of the second clamping member 22 and the clamping plate 211 with the pile body 3 flat, the contact areas of the second clamping member 22 and the clamping plate 211 with the pile body 3 can be increased, thereby increasing the friction between the elastic clamp and the pile body 3.
[0065] The elastic clamp for assisting pile driving further includes a limiting column 44 , which is sleeved in the spring. The limiting column 44 and the spring are coaxially arranged, and the limiting column 44 passes through the connecting plate 212 and is connected to the second clamping member 22 .
[0066] By providing the limiting column 44, the ability of the spring to expand and contract along the axial direction of the limiting column 44 is improved, and the stability of the spring during expansion and contraction is improved.
[0067] The elastic clamp for assisting pile driving also includes a connecting piece 43 . The number of the elastic components 41 is 3, the number of the adjusting components 42 is 2, the elastic components 41 are all connected to the connecting piece 43 , and the two adjusting components 42 are connected to the three elastic components 41 via the connecting piece 43 .
[0068] By providing three elastic components 41 and two adjusting components 42, the clamping force of the elastic clamp on the pile body 3 can be improved, thereby improving the reliability of the elastic clamp; by providing a connecting piece 43, the connecting piece 43 is connected to the three elastic components 41. When the adjusting component 42 is operated, the two adjusting components can drive the three elastic components 41 to compress or extend through the connecting piece 43, thereby improving the ability of the three elastic components 41 to compress or extend synchronously, making the force of the elastic component 41 on the clamping part 2 more uniform, thereby improving the stability of the elastic component 41.
[0069] The connecting member 43 is a connecting plate.
[0070] The clamping portion 2 is a rectangular parallelepiped, and the three elastic components 41 and the two adjusting components 42 are all arranged along the symmetry axis of the length direction of the clamping portion 2 .
[0071] By arranging the three elastic components 41 and the two adjusting components 42 along the symmetry axis in the length direction of the clamping part 2, the ability of the clamping part 2 to maintain balance when subjected to force can be improved, and the tilt or deviation caused by asymmetric load can be reduced. At the same time, the elastic components 41 and the adjusting components 42 arranged along the symmetry axis can evenly distribute the force acting on the clamping part 2, thereby improving the overall rigidity and reducing the probability of deformation.
[0072] The elastic components 41 and the adjusting components 42 are arranged alternately.
[0073] By staggering the three elastic members 41 and the two adjusting members 42, it is helpful to more effectively transmit and disperse the force applied by the elastic members 41 to the clamping part 2, reduce stress concentration, and reduce the probability of local deformation or damage;
[0074] The distance between two adjacent elastic members 41 is equal, and the distance between two adjacent adjustment members 42 is equal.
[0075] By making the distance between two adjacent elastic members 41 equal, and the distance between two adjacent adjustment members 42 equal, it helps to evenly distribute the stress in the elastic clamp, provide more consistent support and bending resistance, and thus improve the overall rigidity and stability.

[0077] A pile driving tool is provided with a connecting rod 1 and the elastic clamp for assisting pile driving, wherein the connecting rod 1 is connected to the elastic clamp for assisting pile driving.
[0078] By setting the connecting rod 1 so that the connecting rod 1 extends out of the water, the piling equipment transmits the force applied to the connecting rod 1 to the pile body 3, thereby driving the pile body 3 into the underwater stratum. By setting the connecting rod 1, the requirements for the working environment of the piling equipment during the piling operation are reduced, and the applicability of the pile driving tool when in use is improved.
[0079] The connecting rod 1 is fixedly connected to an elastic clamp for assisting pile sinking.
[0080] Example 3
[0081] The difference between this embodiment and the first embodiment is that the pile body 3 and the connecting rod 1 are both I-beams, and the cross section of the pile body 3 matches the cross section of the connecting rod 3 .
