Description

Technical Field

[0001] The invention relates to the technical field of underwater piling, and in particular to a construction method for sinking piles. Background Art

[0002] Pile driving is to drive (press) prefabricated piles into the soil by the impact energy of the pile hammer, so that the soil is compacted to achieve the effect of strengthening the pile body. When sinking piles underwater, hammering is generally used to drive the pile body into the underwater stratum and anchor the pile body in the underwater stratum. In the prior art, two construction methods are generally used for underwater pile driving operations:

[0003] One is to use an underwater hydraulic hammer to directly sink the pile underwater. Although the underwater hydraulic hammer can drive steel sheet piles in a 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 changes in the construction environment and reduced equipment stability will further increase construction risks. 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 pile body 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 body. After the vibratory hammer drives the other end of the pile body into the underwater stratum, the excess pile body is cut off through manual underwater cutting operations so that the length of the pile body can meet the needs of subsequent construction operations. Although this method has low cost, it requires underwater cutting operations, which not only makes the construction process complicated, 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 after completing the underwater pile sinking operation using a conventional vibratory hammer, it is necessary to cut off the excess pile body through underwater cutting, which makes the construction process complicated and creates a greater construction risk, and to provide a pile sinking construction method.

[0006] The present invention provides a pile sinking construction method, comprising the following steps:

[0007] S1: Connect the auxiliary pile driving tool to the pile body;

[0008] S2: sink the pile into water;

[0009] S3: Use the piling equipment to drive the end of the auxiliary pile sinking tool that is exposed above the water surface to drive the pile into the ground;

[0010] S4: moving the auxiliary pile driving tool away from the pile body to separate the auxiliary pile driving tool from the pile body;

[0011] The auxiliary pile driving tool comprises a tool body and a connecting rod, wherein the tool body is connected to the connecting rod, the auxiliary pile driving tool clamps the pile body through the tool body, and the connecting rod is a replacement driving component driven by the pile driving equipment.

[0012] When carrying out construction work, the tool body is used to clamp one end of the pile body. When the tool body clamping the pile body is lifted, the pile body is lifted together with the auxiliary pile driving tool. When the tool body is placed underwater, the end of the pile body that is not clamped by the tool body enters the water first, and the pile body enters the water vertically until the end of the pile body that is not clamped by the tool body contacts the underwater ground. At this time, the end of the connecting part away from the pile body can be exposed to the water surface. The piling equipment is used to hit the end of the connecting part exposed to the water surface, and the connecting part is subjected to a force applied downward perpendicular to the ground. The force is transmitted to the underwater ground through the connecting part and the pile body. The underwater ground is squeezed to produce cracks and deformation, so that the pile body can enter the underwater stratum. When the depth of the pile body driven into the stratum reaches the preset burial depth, the connection part is stopped, and the auxiliary pile driving tool is moved in a direction away from the pile body to separate the auxiliary pile driving tool from the pile body. At this time, the pile body is anchored in the underwater stratum, and the underwater pile driving operation is completed.

[0013] With this arrangement, since one end of the connecting portion is exposed above the water surface, a conventional vibratory hammer can be used to strike the end of the connecting portion that clamps the pile body and is exposed above the water surface. After the piling is completed, the auxiliary pile driving tool is moved away from the pile body to separate the auxiliary pile driving tool from the pile body, thereby eliminating the step of separating the auxiliary pile driving tool from the pile body through underwater cutting operations, thereby reducing the complexity and risk of construction.

[0014] The piling equipment may be a vibratory hammer or a pile driver, etc.

[0015] The step S2 comprises:

[0016] S21: Locate the coordinates of the area to be piled;

[0017] S22: moving the auxiliary pile driving tool to the coordinate position of the target area;

[0018] S23: vertically sink the pile into the water;

[0019] S24: Make the end of the pile body away from the auxiliary pile driving tool contact the underwater ground and make the end of the connecting part away from the pile body emerge from the water surface.

[0020] When placing the auxiliary pile driving tool underwater, first use the coordinate positioning tool to locate the coordinates of the area to be piled to improve the accuracy of the construction operation, and then move the tool body holding the pile body to the coordinate position of the target area, with the end of the pile body not clamped by the tool body facing downward. At this position, the pile body is vertically sunk into the water until the end of the pile body not clamped by the tool body contacts the bottom of the water. At this time, the end of the connection part away from the pile body can be exposed to the water surface.

[0021] The coordinate positioning tool may be a GPS or a positioning guide frame, etc.

[0022] The tool body is an elastic clamp, which includes an adjusting member, an elastic member and a clamping portion. The adjusting member is connected to the clamping portion, and the adjusting member is used to open or close the clamping portion. The clamping portion is used to clamp the contact position between the pile body and the connecting rod. When the clamping portion is in a clamping state, the elastic member is in a compressed state.

[0023] By operating the adjusting member, the clamping portion is opened, so that the pile body can be placed in the clamping portion. After the pile body is placed in the clamping portion, the clamping portion is closed by operating the adjusting member until the clamping portion is clamped at a position where the pile body and the connecting rod are in contact. At this time, the clamping portion 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 portion, so that the clamping portion can clamp the pile body, thereby improving the firmness of the elastic clamp to the pile body, and thereby improving the reliability of the elastic clamp when in use.

[0024] The step S1 comprises:

[0025] S11: operating the adjusting member to open the clamping portion;

[0026] S12: placing the pile body into the clamping portion, and making the pile body contact with the connecting rod;

[0027] S13: operating the adjusting member to close the clamping portion, wherein the clamping portion is clamped at a position where the pile body contacts the connecting rod.

[0028] The clamping part 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 with the connecting rod. 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 rise with the connecting rod, and the pile body is anchored in the anchoring medium.

[0029] The clamping portion includes a first clamping member and a second clamping member, the second clamping member is connected to the adjusting member, and the adjusting member is used to make the second clamping member approach to or move away from the first clamping member.

[0030] By arranging a second clamping member to be connected with the adjusting member, the adjusting member can drive the second clamping member to be close to or away from the first 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, 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.

[0031] 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.

[0032] 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.

[0033] The tool body is a hydraulic clamp.

[0034] The step S4 is replaced by comprising:

[0035] S41: releasing the grip of the auxiliary pile driving tool on the pile body;

[0036] S42: moving the auxiliary pile driving tool in a direction away from the pile body.

[0037] By releasing the clamping force of the hydraulic clamp on the pile body, that is, the hydraulic clamp does not apply a clamping force to the pile body, when the auxiliary pile driving tool moves away from the pile body, the auxiliary pile driving tool will not cause the pile body to move in the same direction as the auxiliary pile driving tool, thereby achieving separation of the auxiliary pile driving tool from the pile body, and the pile body can be anchored in the stratum, thereby improving the convenience of construction.

[0038] The hydraulic clamp is provided with a driving device, and the driving device is used to drive the hydraulic clamp to open or close. The driving device comprises an opening and closing signal receiving module and a driving control module.

[0039] When the hydraulic clamp is used to clamp the pile body, an opening signal is sent to the opening and closing signal receiving module, and the opening and closing signal receiving module sends the signal to the drive control module. After receiving the instruction, the drive control module controls the drive device to open the hydraulic clamp so that the state can be placed in the hydraulic clamp, and then a closing signal is sent to the opening and closing signal receiving module, and the opening and closing signal receiving module sends the signal to the drive control module. After receiving the instruction, the drive control module controls the drive device to close the hydraulic clamp. Through this setting, the operator can remotely operate the hydraulic clamp on the shore, which improves the convenience of construction.

[0040] The driving device may be a hydraulic valve, a hydraulic cylinder or a hydraulic motor.

[0041] The contact surface between the tool body and the pile body is a plane.

[0042] When the cross-section of the pile body is rectangular, by making the tool body contact two opposite side surfaces of the pile body, that is, the contact surfaces of the pile body and the tool body are also planes, the contact area between the tool body and the pile body can be increased, thereby increasing the friction coefficient between the tool body and the pile body, and further increasing the maximum static friction between the tool body and the pile body.

[0043] The pile body can also be set as a cylinder or a prism, etc., and the contact surface between the tool body and the pile body is a curved surface or a concave surface that can match the surface of the pile body;

[0044] The connecting part is a connecting rod, and the connecting rod is used to be connected to the piling equipment.

[0045] The connecting rod may be detachably connected to the tool body, may be fixedly connected to the tool body, or may be integrally formed with the tool body.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. The present invention provides a construction method for pile driving, comprising: connecting an auxiliary pile driving tool to a pile body; sinking the pile body underwater; using a pile driving device to hit the end of the auxiliary pile driving tool that is exposed to the water surface, and driving the pile body into the stratum; moving the auxiliary pile driving tool in a direction away from the pile body, so that the auxiliary pile driving tool is separated from the pile body; the auxiliary pile driving tool comprises a tool body and a connecting rod, the tool body is connected to the connecting rod, the auxiliary pile driving tool clamps the pile body through the tool body, and the connecting rod is a replacement hitting component for the pile driving device to hit. Through this arrangement, since one end of the connecting part is exposed to the water surface, a conventional vibrating hammer can be used to hit the end of the connecting part that clamps the pile body that is exposed to the water surface, and after the pile driving is completed, the auxiliary pile driving tool is moved in a direction away from the pile body to separate the auxiliary pile driving tool from the pile body, thereby eliminating the step of separating the auxiliary pile driving tool from the pile body through underwater cutting operations, and reducing the complexity and risk of construction.

[0064] Example 1

[0065] As attached Figure 1-6 As shown, this embodiment provides a pile driving construction method, comprising the following steps:

[0066] S1: Connect the auxiliary pile driving tool 2 to the pile body 3;

[0067] S2: sinking the pile body 3 into water;

[0068] S3: using the piling equipment 1 to drive the end of the auxiliary pile driving tool 2 exposed above the water surface, so as to drive the pile body 3 into the stratum;

[0069] S4: moving the auxiliary pile driving tool 2 away from the pile body 3, so that the auxiliary pile driving tool 2 is separated from the pile body 3;

[0070] The auxiliary pile driving tool 2 includes a tool body 22 and a connecting rod 21 . The tool body 22 is connected to the connecting rod 21 . The auxiliary pile driving tool 2 clamps the pile body 3 through the tool body 22 . The connecting rod 21 is a replacement component for the pile driving device 1 .

[0071] When the pile body 3 is lowered to the bottom of the water, the pile 3 is lowered to the bottom of the water, and the pile body 3 is lowered to the bottom of the water.

[0072] With this arrangement, since one end of the connecting portion is exposed above the water surface, a conventional vibratory hammer can be used to strike the end of the connecting portion that clamps the pile body 3 and is exposed above the water surface. After the piling is completed, the auxiliary pile driving tool 2 is moved away from the pile body 3 to separate the auxiliary pile driving tool 2 from the pile body 3, thereby eliminating the step of separating the auxiliary pile driving tool 2 from the pile body 3 through underwater cutting operations, thereby reducing the complexity and risk of the construction.

[0073] The pile driving equipment 1 is a vibratory hammer.

[0074] The step S2 comprises:

[0075] S21: Locate the coordinates of the area to be piled;

[0076] S22: moving the auxiliary pile driving tool 2 to the target area coordinate position;

[0077] S23: vertically sinking the pile body 3 into the water;

[0078] S24: Make the end of the pile body 3 away from the auxiliary pile driving tool 2 contact the underwater ground and make the end of the connecting part away from the pile body 3 emerge from the water surface.

[0079] When the auxiliary pile driving tool 2 is placed underwater, the coordinates of the area to be piled are first located using a coordinate positioning tool to improve the accuracy of the construction operation. Then the tool body holding the pile body 3 is moved to the coordinate position of the target area, with the end of the pile body 3 not clamped by the tool body facing downward. At this position, the pile body 3 is vertically sunk into the water until the end of the pile body 3 not clamped by the tool body contacts the bottom of the water. At this time, the end of the connection part away from the pile body 3 can be exposed above the water surface.

[0080] The coordinate positioning tool is a positioning guide frame.

[0081] The tool body is an elastic clamp 4, which includes an adjusting member 41, an elastic member 42 and a clamping portion 43. The adjusting member 41 is connected to the clamping portion 43. The adjusting member 41 is used to open or close the clamping portion 43. The clamping portion 43 is used to clamp the contact position between the pile body 3 and the connecting rod 21. When the clamping portion 43 is in the clamping state, the elastic member 42 is in a compressed state.

[0082] By operating the adjusting member 41, the clamping portion 43 is opened, so that the pile body 3 can be placed in the clamping portion 43. After the pile body 3 is placed in the clamping portion 43, the clamping portion 43 is closed by operating the adjusting member 41 until the clamping portion 43 is clamped at the position where the pile body 3 and the connecting rod 21 are in contact. At this time, the clamping portion 43 is in a clamping state. In the clamping state, the elastic member 42 is compressed by the adjusting member 41, so that the elastic member 42 applies a pre-tightening force to the pile body 3 through the clamping portion 43, so that the clamping portion 43 can clamp the pile body 3, thereby improving the firmness of the elastic clamp 4 clamping the pile body 3, and thereby improving the reliability of the elastic clamp 4 when in use.

[0083] The step S1 comprises:

[0084] S11: operating the adjusting member 41 to open the clamping portion 43;

[0085] S12: putting the pile body 3 into the clamping portion 43 and making the pile body 3 contact with the connecting rod 21;

[0086] S13 : operating the adjusting member 41 to close the clamping portion 43 , so that the clamping portion 43 is clamped at a position where the pile body 3 contacts the connecting rod 21 .

[0087] The clamping portion 43 is clamped at the contact position between the pile body 3 and the connecting rod 21, and the end of the pile body 3 close to the connecting rod 21 can be connected to the connecting rod 21. The piling equipment 1 can drive the pile body 3 clamped by the elastic clamp 4 into the anchoring medium by injecting the connecting rod 21. When the pile body 3 is driven into the anchoring medium to a preset depth, the connecting rod 21 is lifted. Since the pile body 3 can meet the pull-out resistance, the elastic clamp 4 can be separated from the pile body 3 and rises with the connecting rod 21, and the pile body 3 is anchored in the anchoring medium.

[0088] The clamping portion 43 includes a first clamping member 44 and a second clamping member 45 . The second clamping member 45 is connected to the adjusting member 41 . The adjusting member 41 is used to make the second clamping member 45 approach to or move away from the first clamping member 44 .

[0089] By setting the second clamping member 45 connected to the adjusting member 41, the adjusting member 41 can drive the second clamping member 45 to approach or move away from the first clamping member 44, so as to realize the opening or closing of the clamping part 43. By only changing the relative position of the second clamping member 45 and the first clamping member 44, the complexity of the structure of the clamping part 43 is reduced, thereby reducing the convenience of operating the clamping part 43 and improving the reliability of the elastic clamp 4.

[0090] The first clamping member 44 includes a clamping plate 441 and a connecting plate 442, the second clamping member 45 is located between the clamping plate 441 and the connecting plate 442, the adjusting member 41 is a bolt, the elastic member 42 is a spring, and both the adjusting member 41 and the elastic member 42 pass through the connecting plate 442 to be connected to the second clamping member 45.

[0091] The adjusting member 41 and the elastic member 42 are both connected to the second clamping member 45 through the connecting plate 442, so that the second clamping member 45 can move relative to the clamping plate 441, while the first clamping member 44 is immobile, which can increase the overall rigidity of the elastic clamp 4; at the same time, the second clamping member 45 is set close to or away from the clamping plate 441, which simplifies the operation method of the elastic clamp 4 and improves the convenience of using the elastic clamp 4.

[0092] The contact surface between the elastic clamp 4 and the pile body 3 is a plane.

[0093] The cross section of the pile body 3 is rectangular. By making the elastic clamp 4 contact two opposite side surfaces of the pile body 3, that is, the contact surfaces of the pile body 3 and the elastic clamp 4 are also planes, the contact area between the elastic clamp 4 and the pile body 3 can be increased, thereby increasing the friction coefficient between the elastic clamp 4 and the pile body 3, and thereby increasing the maximum static friction between the elastic clamp 4 and the pile body 3.

[0094] The connecting portion is a connecting rod 21 , and the connecting rod 21 is used to connect with the piling equipment 1 .

[0095] The connecting rod 21 is fixedly connected to the elastic clamp 4 .

[0096] Example 2

[0097] As attached Figure 7-8 As shown, the tool body is a hydraulic clamp 5.

[0098] The step S4 is replaced by comprising:

[0099] S41: releasing the grip of the auxiliary pile driving tool 2 on the pile body 3;

[0100] S42: moving the auxiliary pile driving tool 2 in a direction away from the pile body 3.

[0101] By releasing the clamping force of the hydraulic clamp 5 on the pile body 3, that is, the hydraulic clamp 5 does not apply a clamping force to the pile body 3, when the auxiliary pile driving tool 2 moves away from the pile body 3, the auxiliary pile driving tool 2 will not cause the pile body 3 to move in the same direction as the auxiliary pile driving tool 2, thereby achieving the separation of the auxiliary pile driving tool 2 and the pile body 3, and the pile body 3 can be anchored in the stratum, thereby improving the convenience of construction.

[0102] The hydraulic clamp 5 is provided with a driving device 51, and the driving device 51 is used to drive the hydraulic clamp 5 to open or close. The driving device 51 includes an opening and closing signal receiving module and a driving control module.

[0103] When the hydraulic clamp 5 is used to clamp the pile body 3, an opening signal is sent to the opening and closing signal receiving module, and the opening and closing signal receiving module sends the signal to the drive control module. After receiving the instruction, the drive control module controls the drive device 51 to open the hydraulic clamp 5 so that the state can be placed in the hydraulic clamp 5, and then a closing signal is sent to the opening and closing signal receiving module, and the opening and closing signal receiving module sends the signal to the drive control module. After receiving the instruction, the drive control module controls the drive device 51 to close the hydraulic clamp 5. Through this setting, the operator can remotely operate the hydraulic clamp 5 on the shore, which improves the convenience of construction.

[0104] The driving device 51 is a hydraulic cylinder.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
