[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0023] The pile foundation installation device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0024] like Figure 1 As shown, the pile foundation installation device 100 according to an embodiment of the present invention includes a floating component 1, a positioning component 2, and a pile clamping component 3.
[0025] Floating component 1 is used to float on the sea surface and for transporting pile foundations. Specifically, such as... Figure 1 As shown, the floating component 1 can float on the sea surface, and the pile foundation can be placed inside the floating component 1, so that the floating component 1 can transport the pile foundation to the pile driving area.
[0026] Positioning element 2 is mounted on floating element 1 so that it moves with floating element 1. When floating element 1 moves to a preset position, the pile foundation passes through positioning element 2 and is embedded in the seabed surface to position floating element 1. Specifically, as follows... Figure 1As shown, the positioning component 2 can be a positioning ring. The positioning component 2 is fixedly installed on the outer circumferential surface of the floating component 1. The floating component 1 can be transported to the pile driving area with the positioning component 2. The pile foundation is a positioning pile. The upper end of the positioning pile passes through the positioning component 2, and the lower end of the positioning pile passes through the seabed surface, so that the positioning pile positions the floating component 1 through the positioning component 2.
[0027] The pile clamping component 3 is mounted on the floating component 1 so that the floating component 1 can move the pile clamping component 3. The pile clamping component 3 is used to install the pile foundation. Specifically, as shown... Figure 1 As shown, the pile clamping component 3 is set on the outer circumference of the floating component 1 and is transported to the pile driving area along with the floating component 1. The pile foundation is transported to the pile clamping component 3, and the pile foundation is positioned by the pile clamping component 3. During the pile driving process, the pile clamping component 3 tightly clamps the pile body of the pile foundation through a mechanical arm or hydraulic system to ensure that the pile body does not shift or tilt when driven into the soil or rock layer, and to prevent the pile body from deviating from the predetermined position due to external forces during construction, thus ensuring the quality and stability of the pile foundation.
[0028] The pile foundation installation device 100 of this invention includes a floating component 1, a positioning component 2, and a pile clamping component 3. The floating component 1 moves the pile foundation to the construction area, and the positioning component 2 positions the floating component 1, fixing it in the construction area. The pile clamping component 3 ensures the installation efficiency and stability of the pile foundation. Compared with related technologies, it eliminates the need for an offshore platform, reducing the cost of pile foundation installation. Furthermore, the floating component 1 can be moved according to the actual conditions of the construction area, improving the installation flexibility of the pile foundation.
[0029] In some embodiments, the positioning element 2 includes a first positioning element 21 and a second positioning element 22, both of which are disposed on the floating element 1 and along both ends of the floating element 1, so that when the floating element 1 moves to a preset position, the pile foundation passes through at least one of the first positioning element 21 and the second positioning element 22 into the seabed surface to position the floating element 1. Specifically, as Figure 1 As shown, the first positioning element 21 and the second positioning element 22 are respectively arranged at the left and right ends of the floating element 1 and are spaced apart from each other in the left and right direction, so that the positioning pile is positioned by the first positioning element 21 and the second positioning element 22.
[0030] In some embodiments, there are multiple pile-holding members 3, and the multiple pile-holding members 3 are spaced apart along the width direction of the floating member 1 (e.g., Figure 1 The front-to-back direction (as shown) is arranged as a first row and a second row, with the first row located on one side of the float 1 and including several rows along the length direction of the float 1 (e.g., Figure 1 The pile-holding members 3 are spaced apart in the left-right direction (as shown). The second row is located on the other side of the floating member 1 and includes several pile-holding members 3 spaced apart along the length of the floating member 1. Specifically, as shown... Figure 1 As shown, the first row is set on the front side of the floating component 1, and the second row is set on the rear side of the floating component 1. The first and second rows include pile clamping components 3 arranged at equal intervals in the left and right directions. Thus, multiple pile foundations can be positioned by multiple pile clamping components 3, which improves the installation efficiency of the pile foundation installation device 100.
[0031] In some embodiments, the pile clamping member 3 includes a first pile clamping member 31, a second pile clamping member 32, a third pile clamping member 33, and a fourth pile clamping member 34. The first pile clamping member 31 and the second pile clamping member 32 are located on one side of the floating member 1 and are spaced apart along the length direction of the floating member 1. The third pile clamping member 33 and the fourth pile clamping member 34 are located on the other side of the floating member 1 and are spaced apart along the length direction of the floating member 1. The first pile clamping member 31 and the third pile clamping member 33 are spaced apart and opposite to each other along the width direction of the floating member 1. The second pile clamping member 32 and the fourth pile clamping member 34 are spaced apart and opposite to each other along the width direction of the floating member 1. Thus, by using the first pile clamping member 31, the second pile clamping member 32, the third pile clamping member 33, and the fourth pile clamping member 34, four pile foundations are installed in the pile driving area, making the pile foundation installation device 100 more rationally configured.
[0032] In some embodiments, the floating component 1 is a barge. Because barges have a large displacement, they can remain stable at sea or in rivers, unaffected by waves and currents. Barges can carry a large amount of construction equipment and materials, and thus, pile hammers, vibratory hammers, and pile foundations can be transported by barges.
[0033] In some embodiments, the pile gripper 3 is a pile clamp. Thus, during the pile driving process, the pile clamp is used to firmly hold the pile body by means of a mechanical arm or hydraulic system, ensuring the verticality and positional accuracy of the pile body.
[0034] In some embodiments, the length of the floating component 1 is greater than 18.4m, and the width of the floating component 1 is less than 7.8m. Therefore, the barge's size design ensures sufficient stability and load-bearing capacity during construction, while avoiding compromising flexibility due to excessive size, making the placement of the floating component 1 more reasonable.
[0035] In some embodiments, the outer peripheral surfaces of the float 1 and the pile clamp 3 are coated with an anti-corrosion material. Specifically, the outer peripheral surfaces of the float 1 and the pile clamp 3 are painted, which can effectively prevent corrosion, extend the service life of the float 1 and the pile clamp 3, and reduce maintenance costs.
[0036] In some embodiments, the pile foundation installation device 100 further includes a crane vessel located on one side of the floating member 1, which is used to lift the pile foundation. Thus, the pile foundation is lifted by the crane vessel so that it is installed within the positioning member 2 and the pile clamping member 3.
[0037] In some embodiments, the pile foundation installation device 100 further includes a measuring and positioning element 2, which is disposed on the floating element 1 and is used to detect the position of the floating element 1. Thus, the measuring and positioning element 2 is a GPS locator, which is used to locate the position of the floating element 1 and ensure that the floating element 1 moves into the pile driving area.
[0038] According to the pile foundation construction method of the present invention, using the pile foundation installation device 100 of any of the above embodiments, the method includes steps S1-S3:
[0039] S1: The pile foundation is placed inside the floating component 1 of the foundation installation device, and the floating component 1 carries the pile foundation to the pile driving area. Thus, the floating component 1 carries the pile foundation to the pile driving area.
[0040] S2: The pile foundation is lifted by a crane ship. The pile foundation penetrates the seabed by its own weight through the positioning piece 2. The pile hammer is lifted to the top of the pile foundation by the auxiliary hook of the crane ship. The pile foundation is driven by vibration. The pile foundation penetrates into the seabed to a certain depth.
[0041] Specifically, the main hook and auxiliary hook of the crane vessel "Ruihang 09" are used to lift and turn the steel pipe piles. The lifting point of the main hook is 5.2m from the top of the pile, and the lifting point of the auxiliary hook is 5.2m from the bottom of the pile. When the pile is lifted, the main hook and auxiliary hook are lifted at the same time. When the pile is more than 2m away from the deck, the main hook of the upper lifting point is pulled back with force to slowly erect the pile until the pile foundation is basically vertical. Then, the crane boom is rotated to feed the pile into the positioning piece 2. The auxiliary hook lifting point is released, and the pile hammer (vibratory hammer) is lifted to the top of the pile by the auxiliary hook of the crane vessel for vibratory pile driving. During this process, the verticality of the pile foundation is controlled by two 90° intersecting theodolites, and the elevation of the pile top is controlled by a level, so that the pile foundation is installed in the positioning piece 2 to position the floating piece 1.
[0042] S3: The pile foundation is lifted by a crane ship into the pile clamp 3 of the foundation installation device. The pile foundation penetrates into the seabed by its own weight. The pile hammer is lifted to the top of the pile foundation by the auxiliary hook of the crane ship. The pile foundation is driven by vibration. The pile foundation penetrates into the seabed to a certain depth.
[0043] Specifically, the main hook and auxiliary hook of the crane vessel "Ruihang 09" were used to lift and turn the steel pipe piles. The lifting point of the main hook was 5.2m from the top of the pile, and the lifting point of the auxiliary hook was 5.2m from the bottom of the pile. When lifting the pile, the main hook and auxiliary hook were lifted simultaneously. When the pile was more than 2m away from the deck, the main hook at the upper lifting point was pulled back with force to slowly erect the pile until it was basically vertical. Then, the crane boom was rotated to feed the pile into the pile gripper's opening. The auxiliary hook lifting point was released, and the pile gripper's hydraulic cylinder was adjusted to coordinate with the lifting of the crane boom to adjust the pile foundation in the opening to meet the verticality requirements. The auxiliary hook of the crane vessel was used to lift the pile hammer (vibratory hammer) to the top of the pile for vibratory pile driving, so that the pile foundation was installed in the seabed.
[0044] The pile foundation construction method of this invention has the advantages of simple steps, convenient construction, and high pile foundation installation efficiency, with steps S1-S3.
