DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a shallow-water pile foundation sinking guide work frame and a method of use to solve the technical problem in the related art that the positioning and measurement of pile foundations of pile-based offshore photovoltaic substructures are difficult due to poor offshore operating conditions.

[0031] It should be understood from the above that during the construction process of the pile foundation fixed offshore photovoltaic substructure, the pile foundation is affected by the effects of sea waves, tides, ocean currents, etc., which leads to inaccurate positioning during the installation process and inconvenient construction, making it difficult to ensure the spacing between the various pile foundations of the photovoltaic substructure. Therefore, the device and construction method of this application are adopted.

[0032] For this purpose, this shallow sea pile foundation sinking guide work frame was invented. Through automatic positioning, real-time display and adjustment and other measures, the measurement and positioning construction efficiency is accelerated. Through the truss structure and guide device between multiple piles, the relative error between multiple piles is ensured to meet the requirements.

[0033] Please refer to Figure 1-Figure 4 , a shallow sea pile foundation sinking guide work frame, comprising:

[0034] A plurality of cross beams 3, both ends of which in the length direction are provided with positioning casings for pipe piles to pass through, and the interior of the positioning casings is provided with axial correction components;

[0035] A plurality of connecting sleeves 4, each having a passage therein for inserting and driving piles, and being fixed on the crossbeam 3, and having lifting lugs thereon;

[0036] The position and posture acquisition component is installed on the crossbeam 3 and is used to detect the position information and horizontal posture information of the positioning casing.

[0037] The shallow-water pile foundation sinking guide frame is lowered by hoisting ears, and the posture and position of the shallow-water pile foundation sinking guide frame are adjusted in real time by the position and attitude acquisition component until the implantation is completed; then the shallow-water pile foundation sinking guide frame is fixed on the seabed by the connecting sleeve 4, and then the pipe pile is put into the positioning casing, and the axial correction component is used to ensure that the inclination of the pipe pile does not exceed the standard, thereby achieving accurate implantation and fixation of the shallow-water pile foundation sinking guide frame, and at the same time providing guidance and positioning for the installation of the pipe pile, avoiding the influence of poor offshore operating conditions on the installation of the fixed offshore photovoltaic substructure pile foundation.

[0038] It should be understood that: to achieve the above basic functions, the number of cross beams 3 is at least one, and the number of positioning casings is two; two pipe piles can be positioned at one time. Of course, as the number of cross beams 3 increases, the number of positioning casings also increases, and the positioning construction of multiple pipe piles can be completed at one time. Figures 1 to 4 The permanent piles 11 to be constructed are the pipe piles described above; the stable steel piles 12 are the driven piles described above.

[0039] In some preferred embodiments, reference Figure 4 , the specific structure of the axial correction component is described in detail:

[0040] The axial correction assembly includes a plurality of radial telescopic members 9, which are divided into a first part and a second part arranged up and down; the plurality of radial telescopic members 9 of the first part are distributed in a circular shape, and the plurality of radial telescopic members 9 of the second part are also distributed in a circular shape;

[0041] One end of each radial telescopic member 9 is connected to the inner wall of the positioning casing, and the other end is provided with a guide roller for sliding contact with the pipe pile.

[0042] The positioning casing is provided with radial mounting holes of the same number as the radial telescopic member 9; the radial mounting holes are threaded holes; the radial telescopic member 9 is a screw rod, and the screw rod is threadedly connected to the threaded hole;

[0043] Of course, the positioning casing may also be provided with radial mounting holes having the same number as the radial telescopic members 9; threaded sleeves may be provided in the radial mounting holes; the radial telescopic members 9 may be screw rods, which are threadedly connected to the threaded sleeves.

[0044] In this embodiment, the guide roller is adjusted and moved by the screw rod to match different pile diameters, and is more conducive to the self-sinking of the pipe pile. The first part and the second part of the double-layer guide can also ensure that the inclination of the pipe pile does not exceed the standard.

[0045] In some preferred embodiments, the position and posture acquisition component is explained as follows:

[0046] A collection device mounting base 7 is provided on the crossbeam 3;

[0047] There are two position and attitude acquisition components, which are respectively located at the two ends of the crossbeam 3 ; the position and attitude acquisition components include a GPS positioning detector and a roll gauge installed on the acquisition device mounting base 7 .

[0048] Among them, the installation base 7 of the collection device has a flange base, which is fixed on the crossbeam 3 connected diagonally to the flange base. The flange base is bolted to the vertical pole. Two GPS positioning detectors and two inclinometers placed on the vertical pole automatically collect data for analysis in real time. The software simulation calculation and the display terminal can display and adjust the position of the shallow sea pile foundation sinking guide work frame in real time. The power supply of the instrument is realized through photovoltaic power generation and batteries installed on the top of the vertical pole.

[0049] In some preferred embodiments, in order to ensure the structural stability of the shallow sea pile foundation sinking guide work frame, there are the following preferred implementation methods, specifically:

[0050] There are two crossbeams 3, and the two crossbeams 3 are cross-connected with their center points as intersections; a cross-connecting beam 6 is provided between the two crossbeams 3 and near the intersections; there are two connecting sleeves 4 on each crossbeam 3, and they are distributed on both sides of the center points; a connecting flat link 5 is provided between two adjacent connecting sleeves 4 or between the parts of the two crossbeams 3 that are close to each other.

[0051] The positioning casing includes a first casing 1 and a second casing 2; the vertical length of the first casing 1 is greater than the vertical length of the second casing 2, and there is one first casing 1 and three second casings 2. With this one-long-and-many-short arrangement, after the single-point long casing enters the seabed, the horizontal position and inclination of the guide frame can be quickly adjusted through displacement and rotation.

[0052] In some preferred embodiments, an anti-sinking plate 10 is provided outside the positioning casing, and the anti-sinking plate 10 includes a circular plate, and a plurality of vertical ribs connected to the positioning casing are provided on the top of the circular plate; and a plurality of through holes are provided on the circular plate. The anti-sinking plate is made of a steel plate with holes, and the elevation position of the anti-sinking plate 10 is basically set at a certain distance below the top elevation of the seabed. The area of ​​the anti-sinking plate 10 is calculated and set according to the overall weight of the guide frame. The area of ​​the anti-sinking plate can be adjusted according to the actual situation during actual use to ensure that the entire guide frame is placed stably and is conducive to pulling out of the seabed.

[0053] Furthermore, a walkway plate 8 for construction workers to walk on is provided on the crossbeam 3. The above components and the components themselves are connected by bolt flanges, which are easy to install and disassemble and can be recycled. The elevation of each component is basically above the average high tide level to reduce the impact of wave force. At the same time, no anti-floating design is required. A walkway plate 8 is provided on the crossbeam 3 to facilitate construction operations. A lifting lug is provided on the connecting sleeve 4 as a lifting point for the guide frame. Steel piles can be inserted into the seabed in the sleeve to enhance the offshore stability of the guide frame.

[0054] The present application also proposes a shallow sea pile foundation sinking method, which comprises the following steps:

[0055] Step 100, according to the construction parameters of the pipe pile, the height and relative spacing of the positioning casing and the area of ​​the anti-sinking plate 10 are obtained, and a shallow sea pile foundation sinking guide work frame is manufactured;

[0056] The above construction parameters are the relative spacing and positioning information between the permanent piles to be constructed, as well as the seabed elevation and tide level, which can ensure that the elevation of each component is basically above the average high tide level to reduce the impact of wave force, and no anti-floating design is required.

[0057] Step 101, hoisting the shallow sea pile foundation sinking guide operation frame to above the operation area, and then lowering it in combination with the position information and horizontal posture information of the positioning casing detected in real time by the position and posture acquisition component;

[0058] Step 102, after being lowered to the seabed, the driven pile is passed through the connecting sleeve 4 and connected to the seabed to complete the temporary fixing operation of the shallow sea pile foundation sinking guide work frame;

[0059] Step 103: Place the pipe pile from the positioning casing to carry out the pipe pile installation operation.

[0060] Among them, the elevation of each component is basically above the average high tide level to reduce the impact of wave force. The specific steps of not requiring anti-floating design are:

[0061] The position information and horizontal posture information of the first casing 1 are detected in real time by the position and posture acquisition component; then the first casing 1 is adjusted to be located directly above its designed installation position;

[0062] The first casing 1 is rotated with the center thereof as the rotation point so that all the second casings 2 are located directly above the corresponding designed installation positions;

[0063] The overall vertical lowering of the shallow sea pile foundation sinking guide work frame.

[0064] This method thus reduces the measurement of the installation position of each positioning casing, reduces the measurement steps, and speeds up the positioning process.

[0065] The above construction process can reduce the impact of the offshore construction environment on the positioning and installation of pipe piles. For specific actual construction steps, please refer to the following embodiments:

[0066] First, according to the construction parameters, a shallow-water pile foundation sinking guide frame of corresponding size is manufactured;

[0067] S1, before the seabed operation, the shallow sea pile foundation sinking guide operation frame is assembled, and according to the design of the pile foundation to be constructed, the pile diameter is adjusted by multiple radial telescopic parts 9, and a certain margin is reserved.

[0068] S2, the steel wire rope under the crane hook passes through the lifting lug set on the connecting sleeve 4, and the guide frame is lifted and placed. Before lifting, ensure that the position and posture acquisition component is turned on and works normally, and can display the real-time position data on the screen.

[0069] S3, the crane ship is hoisted and rotated, and the guy rope is manually pulled to assist in adjusting the position of the guide frame. After the absolute position deviation of the first casing 1 is adjusted to meet the requirements, it is lowered to the seabed. After touching the bottom, the real-time picture on the display screen is used to check whether the horizontal position error of the point is within the required range. If not, it is hoisted to a certain height and fine-tuned to meet the requirements. If the horizontal position error of the point meets the requirements, the crane ship's boom is used to rotate the entire guide frame through this point to the position of the other second casing 2; the horizontal position error is basically consistent with the deviation direction and value of the first casing 1.

[0070] S4, after the horizontal position of the shallow-water pile foundation sinking guide frame is adjusted to meet the absolute horizontal error requirements, the self-sinking guide frame can be lowered. During the self-sinking process, the horizontal position and inclination error of the shallow-water pile foundation sinking guide frame should be paid attention to at any time, and adjustments should be made at any time during the process. After all the first casings 1 and second casings 2 of the guide frame are self-sunk into the mud and are stable, check again whether the inclination exceeds the standard. If it exceeds the standard, it can be adjusted by adding ballast weights to the first casings 1 and second casings 2 or lifting a certain point separately.

[0071] S5, after the installation of the shallow sea pile foundation guide frame is completed and the absolute horizontal position and inclination meet the requirements, the hook is released. To ensure the stability of the guide frame in poor sea conditions, steel piles can be inserted into the connecting sleeve 4 to assist in stabilization. Then the pipe piles are lifted in turn, inserted into the corresponding first casing 1 and second casing 2, and the piles are self-sunk.

[0072] S6, after all the piles are placed, they can be driven into place one by one, and the operator uses the walkway plate 8 to retract the radial expansion member 9 and measure the completion data of the pile position. Finally, the guide frame is lifted to carry out the next cycle of operation.
