Description

Technical Field

[0001] This invention relates to a method for constructing a pile stabilization platform, belonging to the field of wind power equipment manufacturing. Background Technology

[0002] In recent years, wind power development in emerging markets has been rapid. Supported by national policies and facing tight energy supplies, China's wind power industry, particularly its wind turbine equipment manufacturing sector, has also risen rapidly, becoming one of the most active wind power hubs globally. This rapid growth in the wind turbine equipment manufacturing industry necessitates the development of fast and efficient methods for constructing stabilization platforms to meet the installation needs of wind turbine equipment.

[0003] The pile stabilization platform is a pile-driving auxiliary equipment tailored for offshore wind turbine foundation construction and installation projects. This platform has a steel structure base, with the top layer serving as the operating platform, the bottom layer as the anti-sinking platform, and four limiting sleeves in the middle. It is a supporting platform for driving the piles of the offshore four-pile jacket foundation (hereinafter referred to as "engineering piles"). The main structure is based on a pipe frame, mainly composed of four auxiliary pile sleeves, four engineering pile limiting sleeves, and a truss. The center-to-center and left-to-right spacing of each auxiliary pile sleeve is 21m; the outer diameter of the four engineering pile limiting sleeves is φ3300mm, and the center-to-front and left-to-right spacing of each limiting sleeve is 30m. Currently, pile stabilization platforms generally adopt a stacking assembly method during final assembly, followed by extensive high-altitude scaffolding work to complete the assembly of all components. This construction method is not only inefficient but also increases the risk of high-altitude operations during installation, places excessive demands on the site's lifting equipment, and is not conducive to the construction of taller and larger pile stabilization platforms. Summary of the Invention

[0004] This invention provides a pile stabilization platform and its construction method to overcome the shortcomings of existing pile stabilization platforms, which are not only inefficient but also pose risks of high-altitude operations.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] This invention discloses a pile stabilization platform, including a top platform, with a plurality of auxiliary pile sleeves arranged in parallel below the top platform, and adjacent auxiliary pile sleeves are reinforced by supporting steel pipes. Limiting cylinders are provided on both sides of the middle part, and an anti-sinking platform is provided below. Auxiliary piles are connected to the bottom of the anti-sinking platform through the auxiliary pile sleeves.

[0007] The top platform includes a central platform, and the central platform is provided with top platform arms A, B, C and D around its perimeter.

[0008] Furthermore, the limiting cylinder includes limiting cylinder A located around the auxiliary pile sleeve, limiting cylinder B, limiting cylinder C, and limiting cylinder D.

[0009] Furthermore, the auxiliary pile sleeves include auxiliary pile sleeve A, auxiliary pile sleeve B, auxiliary pile sleeve C and auxiliary pile sleeve D located around the perimeter below the top platform.

[0010] Furthermore, the auxiliary piles include auxiliary pile A, auxiliary pile B, auxiliary pile C, and auxiliary pile D, which are matched with the auxiliary pile sleeve.

[0011] Furthermore, the supporting steel pipes include auxiliary pile supporting steel pipe A, auxiliary pile supporting steel pipe B, auxiliary pile supporting steel pipe C and auxiliary pile supporting steel pipe D located between any two auxiliary pile sleeves.

[0012] Furthermore, the anti-sinking platform includes a left panel and a right panel.

[0013] Its construction method adopts a vertical assembly, with the intermediate panels being prefabricated and erected symmetrically, including:

[0014] Step 1: Identify the major components, which include: top platform arm A, top platform arm B, top platform arm C, top platform arm D, top platform middle platform, limiting cylinder A, limiting cylinder B, limiting cylinder C, limiting cylinder D, auxiliary pile sleeve A, auxiliary pile sleeve B, auxiliary pile sleeve C, auxiliary pile sleeve D (each auxiliary pile sleeve is manufactured separately in sections), auxiliary pile A, auxiliary pile B, auxiliary pile C, auxiliary pile D, auxiliary pile support steel pipe A, auxiliary pile support steel pipe B, auxiliary pile support steel pipe C, auxiliary pile support steel pipe D, left anti-sinking platform piece, and right anti-sinking platform piece;

[0015] Step 2: Fabricate large components and install lifting lugs on them, including the following steps:

[0016] Step 1: Assemble the anti-sinking platform in the workshop. The platform is manufactured as a whole, with the left and right sections manufactured separately and simultaneously. On both the front and back sides of the left and right anti-sinking platforms, arrange a pair of 80t main lifting lugs and a pair of 40t auxiliary lifting lugs. The pair of 80t main lifting lugs are located on the inner reinforcing plate of the auxiliary pile sleeve section, and the pair of 40t auxiliary lifting lugs are located on the inner reinforcing plate of the auxiliary pile sleeve section on the other side. On the back side of both the left and right anti-sinking platforms, arrange a 20t auxiliary assembly lifting lug, located on the outer reinforcing plate of the auxiliary pile sleeve section.

[0017] Step 2: Fabricate auxiliary pile sleeves A, B, C, and D. The bottom 2500mm and top 2180mm+10900mm of the four sleeves are fabricated separately. For ease of transportation, the middle section of 47920mm is fabricated in two sections of 24080mm and 23840mm in the workshop.

[0018] Step 3: Fabricate the limiting cylinder. The limiting cylinder is fabricated as a whole, and the limiting pins are installed in place. The connecting plate between the limiting cylinder and the auxiliary pile sleeve is installed on the limiting cylinder, and the connecting steel pipe is also pre-installed on the limiting cylinder. Install three 30t lifting lugs and one 16t lifting lug on the side of the top conical section of the limiting cylinder, and insert a φ80 shackle pin into each of the pin holes of the two limiting pin boxes on the side where the complete support pipe is installed.

[0019] Step 4, Phase 1: Top Platform Assembly. After the middle platform of the top platform is completed, four 16t lifting lugs are welded to the ends of the two intersecting φ700x14 steel pipes. The middle platform is then lifted onto a flatbed truck and transferred to the top platform assembly area. Phase 2: After the top platform booms A, B, C, and D are completed, they are welded to the top 2180mm sleeve. Two 20t lifting lugs and two 16t lifting lugs are welded to each of the four booms. The 20t lifting lugs are welded outwards on both sides of the auxiliary pile sleeve, and the 16t lifting lugs are welded to the outer sides of the boom support pipe. Lifting lugs are welded to all four booms. Complete this step, and then transfer the top platform arms to the middle platform area in the order of top platform arm A, top platform arm B, top platform arm C, and top platform arm D respectively. The arms are then positioned and welded to the middle platform in sequence. In the third stage, after the top platform is closed, the 2180mm sleeve and the 10900mm sleeve are closed in place, and the support steel pipe between auxiliary pile sleeve A and auxiliary pile sleeve B is installed. The support steel pipe connected to auxiliary pile sleeve C and auxiliary pile sleeve D is only welded to the top platform, leaving a loose opening at the bottom. An 80t lifting lug is installed on the outside of auxiliary pile sleeve A and auxiliary pile sleeve B at a position 9500mm away from the top platform.

[0020] Step 5: For ease of transportation, auxiliary piles A, B, C, and D are fabricated in four sections of 20020mm + 21600mm + 21800mm + 21580mm. After the 20020mm section is fabricated, the hole is drilled and the accessories are installed. After the bottom three sections are assembled, the hole is drilled and the accessories are installed.

[0021] Step 3: Construct the large, assembled gantry bench and place it in place:

[0022] Step 1: Make 8 170t gantry benches;

[0023] Step 2: Two 170t gantry benches are arranged as a group. The gantry benches in the group are arranged with a horizontal spacing of 1570mm. Two 16mm thick ring plates are placed on top of the gantry benches, and the two gantry benches are connected with H-beam scraps below the ring plates.

[0024] Step 3: Arrange the gantry benches at 21000mm intervals, and spot weld the gantry benches to the ground after leveling the ground;

[0025] Step four: The anti-sinking platform is flipped over and the gantry bench is closed.

[0026] Step 1: Inside the span, the completed anti-sinking platform is flipped over using a set of 80t lifting lugs on the front and a set of 40t lifting lugs on the back, and then loaded onto a modular trolley for transport to the 1000t assembly site.

[0027] Step 2: The anti-sinking platform below 1000t is lifted and placed on the gantry bench using the front lifting lugs, with the auxiliary pile sleeve position corresponding to the gantry bench position;

[0028] Step 3: After the anti-sinking platform 6 is adjusted, it is spot-welded to the gantry bench.

[0029] Step 5, intermediate sheet production:

[0030] Step 1: Arrange two sets of saddles at 21000mm intervals on the open field. Arrange 5 saddles horizontally within each set. Level the saddles using the jig template to ensure that the center height of the template is at the same height.

[0031] Step 2: After the saddle is leveled, transfer the two sections of auxiliary pile sleeve A and auxiliary pile sleeve B, 24080mm and 23840mm respectively, to the formwork and join them together. After the auxiliary pile sleeve A and auxiliary pile sleeve B are connected and welded in place, the stiffening plate is also welded.

[0032] Step 3: Auxiliary pile sleeve C and auxiliary pile sleeve D are manufactured symmetrically with auxiliary pile sleeve A and auxiliary pile sleeve B, repeating steps 1 and 2.

[0033] Step 6: The limiting cylinder and the intermediate plate are joined together.

[0034] Step 1: Limiting cylinders A, B, C, and D are flipped over and lifted in sequence to the 1000t intermediate sheet area;

[0035] Step 2: The limiting cylinder on one side is joined with the auxiliary pile sleeve on one side of the middle piece. The limiting cylinder A corresponds to the auxiliary pile sleeve A, the limiting cylinder B corresponds to the auxiliary pile sleeve B, the limiting cylinder C corresponds to the auxiliary pile sleeve C, and the limiting cylinder D corresponds to the auxiliary pile sleeve D. After positioning, add support at the appropriate position of the limiting cylinder and spot weld the welding position to fix it.

[0036] Step 3: Repeat steps 1 and 2 on the other side of the limiting cylinder;

[0037] Step four: Welding of the two side limiting cylinders is complete;

[0038] Step 5: Repeat steps 1, 2, 3, and 4 for the other piece.

[0039] Step 7: The intermediate sheet is joined to the anti-sinking platform.

[0040] Step 1: Secure the guy rope to the pipe with a rope clamp. Thread steel wire ropes through the upper 700mm pipe and the lower 800mm pipe of the middle section. Insert pins into the two pin holes at the bottom of the two limiting cylinders facing upwards, and pre-thread steel wire ropes or 100T slings into the pins. Suspend them on the upper and lower trolleys respectively. Lift the middle section simultaneously, raising it to the upper position of the bottom anti-sinking platform. Stop the lower trolley and continue to rise and stretch until the steel wire rope of the lower trolley is no longer under tension. Slowly release the hook from the lower trolley and suspend the upper trolley until the middle section is stable.

[0041] Step 2: Secure the wind rope to the pipe with a rope clamp. Thread steel wire ropes through the upper 700mm pipe and the lower 800mm pipe of the middle section. Insert pins into the two pin holes at the bottom of the two limiting cylinders facing upwards, and pre-thread steel wire ropes or 100T slings into the pins. Suspend them on the upper and lower trolleys respectively. Lift the middle section simultaneously, raising it to the upper position of the bottom anti-sinking platform. Stop the lower trolley and continue to rise and stretch until the steel wire rope of the lower trolley is no longer under tension. Slowly release the hook from the lower trolley and suspend the upper trolley until the middle section is stable.

[0042] Step 3: After the middle section is vertical, pull the guy ropes and install the diagonal brace connecting the bottom to the anti-sinking platform. Then, in the shortest possible time, arrange for the other section to be installed in the same way as Step 1 and Step 2. After the two sections are installed, install the auxiliary pile sleeve support steel pipe B and the auxiliary pile sleeve support steel pipe D in the shortest possible time to ensure the overall closing accuracy.

[0043] Step 8: Top-level platform integration:

[0044] Step 1: The top platform is constructed in sections. All accessories are installed before closure. Except for the closure section, the paint is finished on other parts. The water level marks on the sleeve are marked from top to bottom. The water level marks within 1 meter of the closure position will be marked after closure.

[0045] Step 2: After all the top-level platform structures are installed in place, transport them to the 1000t area below for assembly. After confirming the positions of auxiliary pile sleeves A, B, C, and D, install the upper and lower trolley hooks in place, lift them vertically to a height exceeding the assembly position, and then move them horizontally to the final assembly position. Adjust the upper and lower trolleys to ensure that the entire assembly is in place. After spot welding the assembly position, arrange for welding to be completed to ensure the center positioning of the top-level platform's boom.

[0046] Step 3: After welding the closing position and adjusting the dimensions, weld the previously reserved support opening into place;

[0047] Step nine: After all structural welding is completed, the paint repair of all joined parts is completed;

[0048] Step 10: Check the overall dimensions of the pile stabilization platform and the installation integrity of the remaining auxiliary components.

[0049] The beneficial effects achieved by this invention are as follows: Based on the symmetrical structure of the pile stabilization platform, multiple structures are symmetrically manufactured, symmetrical parts are manufactured simultaneously, and the final components are assembled, which greatly reduces the component manufacturing time. The intermediate auxiliary pile sleeve part is manufactured in sections. Except for the top platform and the anti-sinking platform, the rest are manufactured as a whole to reduce the amount of intermediate welding work. Only the auxiliary pile sleeve part needs to be scaffolded to facilitate the assembly of the top platform and the welding of the supporting steel pipes between the panels, which greatly reduces the overall amount of scaffolding work. Through the saving of construction time in the construction process of each part and the precision control of each component in the construction process, not only is the quality of the structure guaranteed, but the construction efficiency of the pile stabilization platform is also greatly improved, providing strong support for the subsequent construction of wind power piles.

[0082] Auxiliary pile 4 includes auxiliary pile A41, auxiliary pile B42, auxiliary pile C43 and auxiliary pile D44 that match the auxiliary pile sleeve 3;

[0083] The supporting steel pipe 5 includes auxiliary pile supporting steel pipe A51, auxiliary pile supporting steel pipe B52, auxiliary pile supporting steel pipe C53 and auxiliary pile supporting steel pipe D54 located between any two auxiliary pile sleeves 3;

[0084] The anti-sinking platform 6 includes a left piece 61 and a right piece 62.

[0085] The construction method of the stabilizing platform adopts a vertical assembly, with the intermediate panels prefabricated and erected symmetrically. It includes:

[0086] Step 1: Identify the major components, which include: top platform arm A11, top platform arm B12, top platform arm C13, top platform arm D14, top platform middle platform 15, limiting cylinders A21, B22, C23, and D24, auxiliary pile sleeves A31, B32, C33, and D34. Each auxiliary pile sleeve is manufactured separately in sections. Auxiliary piles A41, B42, C43, and D44, auxiliary pile support steel pipes A51, B52, C53, and D54, left piece 61, and right piece 62.

[0087] Step 2: Fabricate large components and install lifting lugs on them, including the following steps:

[0088] Step 1: Assemble the anti-sinking platform in the workshop. The platform is made in reverse as a whole, with the left section 61 and the right section 62 manufactured separately and simultaneously. On both sides of the anti-sinking platform, a pair of 80t main lifting lugs and a pair of 40t auxiliary lifting lugs are arranged. The pair of 80t main lifting lugs are located on the inner side of the reinforcing plate of the auxiliary pile sleeve section, and the pair of 40t auxiliary lifting lugs are located on the inner side of the reinforcing plate of the auxiliary pile sleeve section on the other side. On the reverse side of the anti-sinking platform, a 20t auxiliary assembly lifting lug is arranged on the outer side of the reinforcing plate of the auxiliary pile sleeve section.

[0089] Step 2: Fabricate auxiliary pile sleeves A31, B32, C33, and D34. The bottom 2500mm and top 2180mm+10900mm of the four sleeves are fabricated separately. For ease of transportation, the middle section of 47920mm is fabricated in the workshop in two sections of 24080mm and 23840mm.

[0090] Step 3: Fabricate the limiting cylinder. The limiting cylinder is fabricated as a whole, and the limiting pins are installed in place. The connecting plate between the limiting cylinder and the auxiliary pile sleeve is installed on the limiting cylinder, and the connecting steel pipe is also pre-installed on the limiting cylinder. Install three 30t lifting lugs and one 16t lifting lug on the side of the top conical section of the limiting cylinder, and insert a φ80 shackle pin into each of the pin holes of the two limiting pin boxes on the side where the complete support pipe is installed.

[0091] Step 4, Phase 1: Top Platform Assembly. After the middle platform 15 of the top platform is fabricated, four 16t lifting lugs are welded to the ends of the two intersecting φ700x14 steel pipes. The middle platform 15 is then lifted onto a flatbed truck and transferred to the top platform assembly area. Phase 2: After the top platform booms A11, B12, C13, and D14 are fabricated, they are welded to the top 2180mm sleeve. Two 20t lifting lugs and two 16t lifting lugs are welded to each of the four booms. The 20t lugs are welded outwards on both sides of the auxiliary pile sleeve, and the 16t lugs are welded to the outer sides of the boom support pipe. All four booms are then assembled. Do not transport the top platform arms A11, B12, C13, and D14 in that order to the middle platform 15 area of ​​the top platform. The arms are then positioned and welded to the middle platform 15 in sequence. In the third stage, after the top platform is closed, the 2180mm sleeve and the 10900mm sleeve are closed in place, and the support steel pipe between the auxiliary pile sleeve A31 and the auxiliary pile sleeve B32 is installed. The support steel pipe connected to the auxiliary pile sleeve C33 and the auxiliary pile sleeve D34 is only welded to the top platform, leaving a loose opening at the bottom. Install an 80t lifting lug on the outside of the auxiliary pile sleeve A31 and the auxiliary pile sleeve B32 at a position 9500mm away from the top platform.

[0092] Step 5: For ease of transportation, auxiliary piles A41, B42, C43, and D44 are fabricated in four sections of 20020mm + 21600mm + 21800mm + 21580mm. After the 20020mm section is fabricated, the hole is drilled and the accessories are installed. After the bottom three sections are assembled, the hole is drilled and the accessories are installed.

[0093] Step 3: Construct the large, assembled gantry bench and place it in place:

[0094] Step 1: Make 8 170t gantry benches;

[0095] Step 2: Two 170t gantry benches are arranged as a group. The gantry benches in the group are arranged with a horizontal spacing of 1570mm. Two 16mm thick ring plates are placed on top of the gantry benches, and the two gantry benches are connected with H-beam scraps below the ring plates.

[0096] Step 3: Arrange the gantry benches at 21000mm intervals, and spot weld the gantry benches to the ground after leveling the ground;

[0097] Step four: The anti-sinking platform is flipped over and the gantry bench is closed.

[0098] Step 1: Inside the span, the completed anti-sinking platform is flipped over using a set of 80t lifting lugs on the front and a set of 40t lifting lugs on the back, and then loaded onto a modular trolley for transport to the 1000t assembly site.

[0099] Step 2: The anti-sinking platform below 1000t is lifted and placed on the gantry bench using the front lifting lugs, with the auxiliary pile sleeve position corresponding to the gantry bench position;

[0100] Step 3: After the anti-sinking platform 6 is adjusted, it is spot-welded to the gantry bench.

[0101] Step 5, intermediate sheet production:

[0102] Step 1: Arrange two sets of saddles at 21000mm intervals on the open field. Arrange 5 saddles horizontally within each set. Level the saddles using the jig template to ensure that the center height of the template is at the same height.

[0103] Step 2: After the saddle is leveled, transfer the auxiliary pile sleeves A31 and B32, and the two sections of the auxiliary pile sleeves 24080mm and 23840mm respectively, to the formwork for assembly. After the auxiliary pile support steel pipe A51 between the auxiliary pile sleeves A31 and B32 is connected, weld it in place, and the stiffening plate is also welded.

[0104] Step 3: Auxiliary pile sleeves C33 and D34 are manufactured symmetrically with auxiliary pile sleeves A31 and B32, repeating steps 1 and 2.

[0105] Step 6: The limiting cylinder and the intermediate plate are joined together.

[0106] Step 1: Limiting cylinders A21, B22, C23, and D24 are flipped over and lifted in sequence to the 1000t intermediate sheet area.

[0107] Step 2: Close the limiting cylinder on one side with the auxiliary pile sleeve on one side of the middle piece. The limiting cylinder A21 corresponds to the auxiliary pile sleeve A31, the limiting cylinder B22 corresponds to the auxiliary pile sleeve B32, the limiting cylinder C23 corresponds to the auxiliary pile sleeve C33, and the limiting cylinder D24 corresponds to the auxiliary pile sleeve D34. After positioning, add support at the appropriate position of the limiting cylinder and spot weld the welding position to fix it.

[0108] Step 3: Repeat steps 1 and 2 on the other side of the limiting cylinder;

[0109] Step four: Welding of the two side limiting cylinders is complete;

[0110] Step 5: Repeat steps 1, 2, 3, and 4 for the other piece.

[0111] Step 7: The intermediate sheet is joined to the anti-sinking platform.

[0112] Step 1: Secure the wind rope to the pipe with a rope clamp. Thread steel wire ropes through the φ700 pipe at the top and the φ800 pipe at the bottom of the intermediate section. Insert pins into the two pin holes at the bottom of the two limiting cylinders with the bottom facing upwards. Pre-thread steel wire ropes or 100T slings into the pins. Suspend them on the upper and lower trolleys respectively. Lift the intermediate section simultaneously. Raise the intermediate section to the upper part of the bottom anti-sinking platform. Stop the lower trolley. Continue to lift the upper trolley until the steel wire rope of the lower trolley is no longer under tension. Slowly release the hook from the lower trolley. Suspend the upper trolley until the intermediate section is stable.

[0113] Step 2: Secure the wind rope to the pipe with a rope clamp. Thread steel wire ropes through the φ700 pipe at the top and the φ800 pipe at the bottom of the intermediate section. Insert pins into the two pin holes at the bottom of the two limiting cylinders facing upwards, and pre-thread steel wire ropes or 100T slings into the pins. Suspend the intermediate section on the upper and lower trolleys respectively. Lift the intermediate section simultaneously. Raise the intermediate section to the upper part of the bottom anti-sinking platform. Stop the lower trolley and continue to rise and stretch until the steel wire rope of the lower trolley is no longer under tension. Slowly release the hook from the lower trolley and suspend the upper trolley until the intermediate section is stable.

[0114] Step 3: After the middle section is vertical, pull the guy ropes and install the diagonal bracing that connects the bottom to the anti-sinking platform. Then, in the shortest possible time, arrange for the other section to be installed in the same way as Step 1 and Step 2. After the two sections are installed, install the auxiliary pile support steel pipes B52 and D54 in the shortest possible time to ensure the overall closure accuracy.
