[0015] A casting method described in the present application prefabricates the prefabricated berthing structure in a factory. At the installation site, it is only necessary to open slots on the template, set support structures on both sides of the slots, pass support rods through the corresponding lifting holes, and support the two ends of the support rods on the support structures on the corresponding sides. The prefabricated berthing structure is then extended into the slots. Thereafter, a cast-in-place beam structure is cast based on the template, so that the cast-in-place beam structure on the upper part of the high-pile wharf fixes the high-pile wharf berthing component. There is no need to erect and dismantle non-universal templates for the high-pile wharf berthing components, and only the template for the cast-in-place beam structure needs to be erected, which saves time and effort and reduces construction costs.
[0016] Preferably, the steel bars in the cast-in-place beam structure are connected to the support structure, the lifting lug structure and the support rod, so that the connection between the high-pile dock berthing component and the cast-in-place beam structure is more secure.
[0017] Preferably, the template includes a side template, a bottom template and a lifting structure connected to both ends of the bottom template in the length direction, the side template and the bottom template are connected, the slot is located on the bottom template, the supporting structure is arranged on the bottom template, and the lifting structure can drive the bottom template to rise and fall.
[0018] Preferably, the hoisting structure comprises a lower cross beam, a support leg and at least two suspension rod assemblies spaced apart in the width direction of the bottom mold, the lower cross beam is arranged in the width direction of the bottom mold; the support leg supports the lower cross beam; the suspension rod assembly comprises an upper cross beam and at least two vertical suspension rods spaced apart in the transverse direction, the upper cross beam is located above the lower cross beam, the vertical suspension rod passes through the upper cross beam and the lower cross beam, a jacking device is supported between the upper cross beam and the lower cross beam, the jacking device is located between the two vertical suspension rods, and the vertical suspension rods are threadedly matched with a first fixing nut, A first supporting nut and a second fixing nut, the first supporting nut is supported at the bottom of the upper beam, the first fixing nut is located at the top of the upper beam, and the first fixing nut and the first supporting nut can clamp the upper beam from the upper and lower sides of the upper beam, the second fixing nut is located at the top of the lower beam, and the lower beam can support the second fixing nut, the lower part of the vertical suspension rod is connected to the bottom mold, the upper beam is located above the lower beam, the bottom mold is located below the lower beam, and the vertical suspension rod is vertically limitedly connected to the bottom mold.
[0019] The formwork described in the present application, when the bottom form is in use, the legs support the lower cross beam, and the lower cross beam supports the second fixing nut. Since the second fixing nut is threadedly engaged with the vertical hanger, and the lower part of the vertical hanger is connected to the bottom form, the lower cross beam achieves the purpose of stably setting the bottom form in the construction position by supporting the vertical hanger.
[0020] When the bottom mold needs to be disassembled, the lifting device is first adjusted to the extended state, but there is still a certain lifting space; then the first fixing nut and the first supporting nut are clamped to the upper beam from the upper and lower sides of the upper beam; then the lifting device is lifted to make the upper beam rise a first distance H1, and the lower beam is separated from the second fixing nut, and the two are no longer subjected to mutual force, so that the operator can tighten the second fixing nut with an ordinary wrench; the second fixing nut is turned, and the second fixing nut is raised along the vertical suspension rod by a second distance H2, and the second distance H2 is greater than the first distance H1; then the lifting device The bottom mold is then lowered back until the lower cross beam supports the second fixing nut again. At this time, since the vertical hanger is connected to the vertical limit connection of the bottom mold, the vertical hanger drives the bottom mold to fall. Thereafter, the above process is repeated until the bottom mold falls to the target height. The entire process is completed by the operator screwing the first fixing nut, the first supporting nut and the second fixing nut, and cooperating with the lifting device to lift and lower the bottom mold. The entire bottom mold device can make the bottom mold disassembly process do not require the assistance of a large crane. The hanger assembly has a simple structure and low cost, and is suitable for batch arrangement on high-pile docks. Compared with large cranes, it has lower cost and is more cost-effective.
[0021] Moreover, since the lifting structure can form a stable suspension support for the bottom mold, the work of disassembling the bottom mold does not need to be performed on the floating raft. Compared with the working condition where the floating raft floats with the water, the lifting structure of the present application can form a stable suspension support for the bottom mold, which makes it safer for operators to disassemble the bottom mold.
[0022] Preferably, the bottom of the side mold and the bottom mold are hinged.
[0023] Preferably, the bottom formwork comprises a bottom formwork and a beam structure for supporting the bottom formwork, and the beam structure is vertically limitedly connected to the vertical hanger.
[0024] Preferably, the method further includes the step of disassembling the bottom template:
[0025] C1. Separate the upper part of the side mold from the bottom mold and flip the side mold 180° relative to the bottom mold;
[0026] C2. Using the lifting structure to drive the bottom mold and the side mold to descend;
[0027] C3. When the bottom mold falls to a height M from the floating row, it stops falling, and then the side molds are disassembled, and the disassembled parts of the side molds are placed on the floating row.
[0028] C4. Then continue to lower the beam structure, when the bottom mold falls to a height H from the floating row, stop falling, then decompose the bottom template, and place the decomposed parts on the floating row;
[0029] C5. Then continue to lower the beam structure until the beam structure lands on the floating row, and separate the bottom formwork from the lifting structure.
[0030] A casting method described in the present application, when the bottom form is in use, the support legs support the lower cross beam, and the lower cross beam supports the second fixing nut. Since the second fixing nut cooperates with the vertical hanger thread, and the lower part of the vertical hanger is connected to the bottom form, the lower cross beam supports the vertical hanger to achieve the purpose of stably setting the bottom form in the construction position.
[0031] When the bottom form needs to be disassembled, first separate the upper part of the side form from the bottom form, and flip the side form 180° relative to the bottom form to prevent the problem of difficulty in the formwork falling due to excessive vertical friction between the side form and the side wall of the cast-in-place beam structure; then use the lifting structure to drive the bottom form and side form to descend; when the bottom form falls to a height M from the floating row, stop falling, then disassemble the side form, and place the disassembled parts of the side form on the floating row. Then continue to lower the beam structure, and when the bottom form falls to a height H from the floating row, stop falling, then disassemble the bottom template, and place the disassembled parts on the floating row; then continue to lower the beam structure until the beam structure falls on the floating row, and the bottom form and the lifting structure are separated. The entire disassembly process of the side form and the bottom form does not require the assistance of a large crane. The structure of the suspension rod assembly is simple and the cost is low. It is suitable for batch arrangement on high-pile docks. Compared with large cranes, it is cheaper and more cost-saving.
[0032] Moreover, since the lifting structure can form a stable suspension support for the bottom mold, the work of disassembling the side mold and the bottom mold does not need to be performed on the floating raft. Compared with the working condition where the floating raft floats with the water, the lifting structure of the present application can form a stable suspension support for the bottom mold, which makes it safer for operators to disassemble the bottom mold.
[0033] Preferably, using the hoisting structure to drive the bottom mold and the side mold to descend specifically includes the following steps:
[0034] A1. Rotate the first fixing nut and raise the first fixing nut along the vertical boom for a certain distance;
[0035] A2. Lift the lifting device onto the crossbeam for a certain distance;
[0036] A3. Clamp the upper beam by clamping the first fixing nut and the first supporting nut from the upper and lower sides of the upper beam;
[0037] A4. Continue to lift the lifting device to separate the lower beam from the second fixing nut, and the vertical distance between the lower beam and the second fixing nut is the first distance H1;
[0038] A5. Rotate the second fixing nut and raise the second fixing nut along the vertical boom by a second distance H2, wherein the second distance H2 is greater than the first distance H1;
[0039] A6. The lifting device falls back, so that the vertical suspension rod drives the bottom mold to fall until the lower crossbeam supports the second fixing nut again;
[0040] A7. Repeat A1-A6 until the bottom mold drops to the target height.
[0041] A disassembly method described in the present application is that when the bottom mold is in use, the support legs support the lower cross beam, and the lower cross beam supports the second fixing nut. Since the second fixing nut cooperates with the vertical hanger thread, and the lower part of the vertical hanger is connected to the bottom mold, the lower cross beam achieves the purpose of supporting the vertical hanger to stably set the bottom mold in the construction position.
[0042] When the bottom mold needs to be disassembled, the lifting device is first adjusted to the extended state, but there is still a certain lifting space; then the first fixing nut and the first supporting nut are clamped to the upper beam from the upper and lower sides of the upper beam; then the lifting device is lifted to make the upper beam rise a first distance H1, and the lower beam is separated from the second fixing nut, and the two are no longer subjected to mutual force, so that the operator can tighten the second fixing nut with an ordinary wrench; the second fixing nut is turned, and the second fixing nut is raised along the vertical suspension rod by a second distance H2, and the second distance H2 is greater than the first distance H1; then the lifting device The bottom mold is then lowered back until the lower cross beam supports the second fixing nut again. At this time, since the vertical hanger is connected to the vertical limit connection of the bottom mold, the vertical hanger drives the bottom mold to fall. Thereafter, the above process is repeated until the bottom mold falls to the target height. The entire process is completed by the operator screwing the first fixing nut, the first supporting nut and the second fixing nut, and cooperating with the lifting device to lift and lower the bottom mold. The entire bottom mold device can make the bottom mold disassembly process do not require the assistance of a large crane. The hanger assembly has a simple structure and low cost, and is suitable for batch arrangement on high-pile docks. Compared with large cranes, it has lower cost and is more cost-effective.
[0043] Moreover, since the lifting structure can form a stable suspension support for the bottom mold, the work of disassembling the bottom mold does not need to be performed on the floating raft. Compared with the working condition where the floating raft floats with the water, the lifting structure of the present application can form a stable suspension support for the bottom mold, which makes it safer for operators to disassemble the bottom mold.
[0044] Compared with the prior art, the present invention has the following beneficial effects:
[0045] A high-pile dock mooring component described in the present application is achieved by prefabricating the prefabricated mooring structure in a factory. At the installation site, it is only necessary to open slots on the template and set support structures on both sides of the slots, and pass support rods through the corresponding lifting holes.

[0099] In a specific preferred embodiment of the beam structure 13 , the beam structure 13 is formed by two channel steels back to back and welded together via a third plate, and the vertical hanger 8 is located outside the beam structure 13 .
[0100] In a specific preferred embodiment of the beam structure 13, the legs 5 may be H-shaped steel, I-beam, box beam or rectangular tube structure.
[0101] A specific preferred embodiment of the bottom formwork 12 includes a plate and a plurality of transverse ribs connecting the back of the plate. The front of the plate is relatively smooth and serves as a limiting surface for the cast-in-place beam structure 14. The transverse ribs support the plate and increase the stiffness of the plate. The beam structure 13 supports the plate through the transverse ribs.
[0102] In a preferred manner, the hanger assembly 7 includes a bottom cross beam 15, a third fixing nut 17 and a pressure plate 18. A support portion 16 is provided at the bottom of the vertical hanger 8. The support portion 16 supports the bottom cross beam 15, and the end of the corresponding beam structure 13 passes through the gap between the two vertical hangers 8 of the same hanger assembly 7 and is supported on the bottom cross beam 15. The third fixing nut 17 is threadedly matched with the vertical hanger 8, and the third fixing nut 17 can abut against the pressure plate 18, so that the pressure plate 18 and the bottom cross beam 15 form a vertical limit for the beam structure 13.
[0103] In a specific preferred embodiment of the support portion 16 , the support portion 16 is a truncated cone structure with a diameter greater than that of the vertical suspension rod 8 , and is capable of supporting the bottom cross beam 15 .
[0104] A specific preferred embodiment of the bottom cross beam 15 is that the bottom cross beam 15 is formed by two channel steels back to back and welded together by a fourth plate, a gap is provided between the two channel steels for the vertical hanger 8 to pass through, and fourth plates are provided on both sides of the vertical hanger 8.
[0105] In a specific preferred embodiment of the bottom cross beam 15, the support leg 5 can be a channel steel, a box beam or a rectangular tube structure. In this case, a through hole needs to be opened on the channel steel, the box beam or the rectangular tube structure to allow the vertical hanger 8 to pass through.
[0106] Regarding the formwork described in this embodiment, when the bottom form 1 is in use, the supporting legs 5 support the lower cross beam 4, and the lower cross beam 4 supports the second fixing nut 10. Since the second fixing nut 10 is threadedly matched with the vertical hanger 8, and the lower part of the vertical hanger 8 is connected to the bottom form 1, the lower cross beam 4 supports the vertical hanger 8 to stably set the bottom form 1 at the construction position.
[0107] When the bottom mold 1 needs to be disassembled, the lifting device 6 is first adjusted to the extended state, but there is still a certain lifting space; then the first fixing nut 11 and the first supporting nut 9 are clamped on the upper and lower sides of the upper beam 3; then the lifting device 6 is lifted to make the upper beam 3 rise a first distance H1 [the first time is generally 1-2mm, at this time, the displacement space of 1-2mm is provided by the structural deformation of the bottom mold 1 or the axial structural deformation of the vertical suspension rod 8], the lower beam 4 is separated from the second fixing nut 10, and the two are no longer subjected to mutual force, so that the operator can tighten the second fixing nut 10 with an ordinary wrench; rotate the second fixing nut 10, and make the second fixing nut 10 rise along the vertical suspension rod 8 by a second distance H1. Distance H2, the second distance H2 is greater than the first distance H1; then the jacking device 6 falls back until the lower cross beam 4 supports the second fixing nut 10 again. At this time, since the vertical suspension rod 8 is vertically limitedly connected to the bottom mold 1, the vertical suspension rod 8 drives the bottom mold 1 to fall; then the above process is repeated until the bottom mold 1 falls to the target height. The whole process is completed by the operator screwing the first fixing nut 11, the first supporting nut 9 and the second fixing nut 10, and cooperating with the lifting device 6 to lift and lower the bottom mold 1. The whole bottom mold device can make the disassembly process of the bottom mold 1 do not require the assistance of a large crane. The suspension rod assembly 7 has a simple structure and low cost, and is suitable for batch arrangement on high-pile docks. Compared with large cranes, it has lower cost and is more cost-effective.
[0108] Moreover, since the lifting structure 2 can form a stable suspension support for the bottom mold 1, the work of disassembling the bottom mold 1 does not need to be performed on the floating raft. Compared with the working condition where the floating raft floats with the water, the lifting structure 2 of the present application can form a stable suspension support for the bottom mold 1, which makes it safer for the operator to disassemble the bottom mold 1.
[0109] The vertical suspension rod 8 can be set to a stepped structure with a small top and a large bottom to facilitate the rapid installation of each nut.
[0110] A preferred embodiment further comprises a cast-in-place beam structure 14 and a formwork as described in Example 1, and the legs 5 are connected to the cast-in-place beam structure 14 .
[0111] In a preferred manner, the supporting legs 5 are clamped on the cast-in-place beam structure 14 via a U-shaped member 19 .
[0112] In a preferred embodiment, the support leg 5 cooperates with the cast-in-place beam structure 14 in a lateral swinging manner.
[0113] In a specific preferred manner, a vertical through hole is provided on the supporting leg 5, a connecting bolt 20 passes through the vertical through hole and is connected to the cast-in-place beam structure 14, and the supporting leg 5 can swing laterally around the connecting bolt.
[0114] The cast-in-place beam structure 14 is preferably a convex beam or a strip beam structure.
[0115] like Figure 7-14 As shown, a casting method described in this embodiment also includes a method for disassembling the formwork after casting, which preferably includes the following steps:
[0116] C1. Separate the upper part of the side mold from the bottom mold 1, and flip the side mold 180° relative to the bottom mold 1;
[0117] C2. Using the lifting structure 2 to drive the bottom mold 1 and the side mold to descend;
[0118] C3. When the bottom mold 1 falls to a height M from the floating row, it stops falling, and then the side molds are disassembled, and the disassembled parts of the side molds are placed on the floating row.
[0119] C4. Then continue to lower the beam structure 13. When the bottom mold 1 falls to a height H from the floating row, stop falling, then decompose the bottom template 12, and place the decomposed parts on the floating row;
[0120] C5. Then continue to lower the beam structure 13 until the beam structure 13 falls on the floating row, and the bottom mold 1 and the lifting structure 2 are separated.
[0121] In the above scheme: the side form is flipped 180° relative to the bottom form 1 to prevent the problem of difficulty in the formwork falling due to excessive vertical friction between the side form and the side wall of the cast-in-place beam structure 14.
[0122] A specific preferred embodiment is as follows: the bottom of the side mold is hinged to the end of the bottom mold 1.
[0123] A specific preferred embodiment: M height ≤ 20 cm.
[0124] A casting method described in the present application, when the bottom form is in use, the support legs support the lower cross beam, and the lower cross beam supports the second fixing nut. Since the second fixing nut cooperates with the vertical hanger thread, and the lower part of the vertical hanger is connected to the bottom form, the lower cross beam supports the vertical hanger to achieve the purpose of stably setting the bottom form in the construction position.
[0125] When the bottom form needs to be disassembled, first separate the upper part of the side form from the bottom form 1, and flip the side form 180° relative to the bottom form 1 to prevent the problem of the template being difficult to fall due to the excessive vertical friction between the side form and the side wall of the cast-in-place beam structure 14; then use the lifting structure 2 to drive the bottom form 1 and the side form to descend; when the bottom form 1 falls to a height M from the floating row, stop falling, then disassemble the side form, and place the disassembled parts of the side form on the floating row. Then continue to lower the beam structure 13, when the bottom form 1 falls to a height H from the floating row, stop falling, then disassemble the bottom template 12, and place the disassembled parts on the floating row; then continue to lower the beam structure 13 until the beam structure 13 falls on the floating row, and the bottom form 1 and the lifting structure 2 are separated. The entire disassembly process of the side form and the bottom form 1 does not require the assistance of a large crane, the suspension rod assembly has a simple structure and low cost, and is suitable for batch arrangement on high-pile docks. Compared with large cranes, it is cheaper and more cost-saving.
[0126] Moreover, since the lifting structure can form a stable suspension support for the bottom mold, the work of disassembling the side mold and the bottom mold does not need to be performed on the floating raft. Compared with the working condition where the floating raft floats with the water, the lifting structure of the present application can form a stable suspension support for the bottom mold, which makes it safer for operators to disassemble the bottom mold.
[0127] A specific preferred method: using the lifting structure 2 to drive the bottom mold 1 and the side mold to descend specifically includes the following steps:
[0128] A1. Rotate the first fixing nut 11 and raise the first fixing nut 11 along the vertical boom 8 for a certain distance;
[0129] A2. Lift the lifting device 6 up to the upper beam 3 for a certain distance;
[0130] A3. Clamp the first fixing nut 11 and the first supporting nut 9 from the upper and lower sides of the upper beam 3 to the upper beam 3;
[0131] A4. Continue to lift the lifting device 6 to separate the lower cross beam 4 from the second fixing nut 10, and the vertical distance between the lower cross beam 4 and the second fixing nut 10 is the first distance H1; [the first distance H1 is generally 1-2 mm, and at this time, the bottom mold 1 is deformed or the vertical suspension rod 8 is deformed in the axial direction to provide a displacement space of 1-2 mm];
[0132] A5. Rotate the second fixing nut 10 and make the second fixing nut 10 rise along the vertical boom 8 by a second distance H2, wherein the second distance H2 is greater than the first distance H1;
[0133] A6. The lifting device 6 falls back, so that the vertical suspension rod 8 drives the bottom mold 1 to fall until the lower beam 4 supports the second fixing nut 10 again;
[0134] A7. Repeat A1-A6 until the bottom mold 1 falls to the target height.
[0135] When the bottom form 1 is in use, the supporting legs 5 support the lower cross beam 4, and the lower cross beam 4 supports the second fixing nut 10. Since the second fixing nut 10 is threadedly matched with the vertical hanger 8, and the lower part of the vertical hanger 8 is connected to the bottom form 1, the lower cross beam 4 supports the vertical hanger 8 to stably set the bottom form 1 at the construction position.
[0136] When the bottom mold 1 needs to be disassembled, the lifting device 6 is first adjusted to the extended state, but there is still a certain lifting space; then the first fixing nut 11 and the first supporting nut 9 are clamped on the upper and lower sides of the upper beam 3; then the lifting device 6 is lifted to make the upper beam 3 rise by a first distance H1 [the first time is generally 1-2mm, at this time, the displacement space of 1-2mm is provided by the structural deformation of the bottom mold 1 or the axial structural deformation of the vertical suspension rod 8], the lower beam 4 is separated from the second fixing nut 10, and the two are no longer subjected to mutual force, so that the operator can tighten the second fixing nut 10 with an ordinary wrench; the second fixing nut 10 is turned, and the second fixing nut 10 is raised along the vertical suspension rod 8 by a second distance H2 [the second distance H 2 is generally 200-500mm], the second distance H2 is greater than the first distance H1; then the jacking device 6 falls back until the lower cross beam 4 supports the second fixing nut 10 again. At this time, since the vertical suspension rod 8 is vertically limitedly connected to the bottom mold 1, the vertical suspension rod 8 drives the bottom mold 1 to fall; then the above process is repeated until the bottom mold 1 falls to the target height. The whole process is completed by the operator screwing the first fixing nut 11, the first supporting nut 9 and the second fixing nut 10, and cooperating with the lifting device 6 to lift and lower the bottom mold 1. The whole bottom mold device can make the disassembly process of the bottom mold 1 do not require the assistance of a large crane. The suspension rod assembly 7 has a simple structure and low cost, and is suitable for batch arrangement on high-pile docks. Compared with large cranes, it has lower cost and is more cost-saving.
[0137] Moreover, since the lifting structure 2 can form a stable suspension support for the bottom mold 1, the work of disassembling the bottom mold 1 does not need to be performed on the floating raft. Compared with the working condition where the floating raft floats with the water, the lifting structure 2 of the present application can form a stable suspension support for the bottom mold 1, which makes it safer for the operator to disassemble the bottom mold 1.
[0138] In a preferred embodiment, a steel pipe pile 30 is provided at the lower part of the cast-in-place beam structure 14, and a corbel is detachably connected to the steel pipe pile 30, and the corbel is used to support the bottom form 1. When the bottom form 1 includes a bottom form 12 and a beam structure 13 for supporting the bottom form 12:
[0139] In a preferred embodiment, before step A1, a step of disassembling the corbel is further included: connecting the corbel to the beam structure 13, and then disassembling and separating the corbel from the steel pipe pile 30;
[0140] The corbel is connected to the beam structure 13 to prevent the corbel from falling directly onto the floating row after being disassembled, thereby causing structural damage to the floating row. In addition, the corbel can be slowly lowered along with the bottom form 1 at a later stage, thus omitting the separate corbel lowering step and saving construction time.
[0141] Preferably, the bracket is configured as two semicircular structures, which are connected to the steel pipe pile 30 by bolts. During construction, small holes are provided on the bottom template 12, and the operator inserts a tool (such as a bolt) through the small hole on the bottom template 12, and then removes the bolt.
[0142] Preferably, in A7, when the bottom mold 1 falls to a height H from the floating row, it stops falling, then the bottom mold plate 12 is disassembled, and the disassembled parts are placed on the floating row, and then the beam structure 13 is continued to be lowered until the beam structure 13 falls on the floating row, and the bottom mold 1 and the lifting structure 2 are separated.
