[0002] Offshore pile foundation construction refers to the installation of pile foundation facilities at sea to fix buildings or bridges and bear the loads transferred to them.

[0003] The existing offshore pile foundation driving methods are mainly divided into floating pile stabilization platform, bottom-seated pile stabilization platform and negative pressure bucket pile stabilization platform. The floating pile stabilization platform adopts a pile stabilization platform with auxiliary piles and platform separated, which are connected as a whole through welding after erection; the bottom-seated pile stabilization platform is based on the original traditional independent pile stabilization platform, and the limit sleeve is extended to the seabed surface and a dustproof plate structure is set, so the overall rigidity of the platform is large; the negative pressure bucket pile stabilization platform is an offshore platform with a closed upper end and an open bottom end, which is suitable for engineering areas where the shallow soil is clay.

[0004] However, the construction of fixed offshore photovoltaic piling is limited by the "shallow" construction waters. When using a floating pile stabilization platform, the operating vessel can only work during the tide, and it is difficult to complete the construction within the effective tide period; the use of a bottom-mounted pile stabilization platform requires larger lifting equipment for construction, but due to the "shallow" water, it is impossible to use construction vessels with a larger draft for operation; the negative pressure bucket pile stabilization platform, because its operating principle is to form negative pressure by pumping water, it sinks to the designed depth under the action of its own gravity and water pressure, but due to the "shallow" water, it is difficult to sink to the required depth.

[0005] Therefore, there is an urgent need for a stable pile positioning platform that can be used for efficient piling in shallow water conditions. Utility Model Content

Among them, the fixed base includes a plurality of fixed piles 1 arranged at intervals along the circumference, and the positioning frame 2 is provided with a plurality of lifting members 3 arranged at intervals along the circumference. The plurality of lifting members 3 are arranged on the plurality of fixed piles 1 one by one, and each lifting member 3 is adjustable relative to the position of the corresponding fixed pile 1 in the vertical direction; the plurality of pile holding frames 4 are arranged on the side of the plurality of lifting members 3 away from the positioning frame 2 one by one, and each pile holding frame 4 is provided with a fixed channel 40; the plurality of guide cylinders 5 are detachably arranged in the fixed channel 40 one by one, and each guide cylinder 5 is provided with an installation channel 50 for allowing the pile foundation to pass through. By adjusting the vertical position of the lifting member 3 relative to the fixed pile 1, the position and horizontality of the guide cylinder 5 arranged on the pile holding frame 4 are adjusted, thereby ensuring the accuracy of subsequent piling. In addition, the piling construction of multiple pile foundations can be carried out simultaneously, which is conducive to improving the working efficiency. In addition, the guide cylinder 5 is detachably disposed in the fixed channel 40 , and guide cylinders 5 of different sizes can be replaced according to the size of the pile foundation to improve the applicability of the positioning platform.

[0044] For example, in this embodiment, four fixed piles 1, four lifting members 3 and four pile-holding frames 4 are provided; the number in other embodiments can be set as required.

[0045] Specifically, Figure 1 As shown, each fixed pile 1 is provided with a plurality of reinforcing plates at intervals along the circumference to improve the stability of the fixed pile 1 supported on the seabed mud layer.

The positioning frame 2 and the pile holding frame 4 are both connected to the outer wall of the lifting sleeve. The above arrangement not only drives the lifting member 3 to adjust its position relative to the fixed pile 1 in the vertical direction, but also has a certain protective effect on the jacking mechanism 7, so that it is protected from the invasion of waves, thereby extending the service life and reducing the maintenance frequency.

[0050] Specifically, two door-shaped members 30 are arranged between the lifting mechanism 7 and the lifting sleeve, and the two door-shaped members 30 are arranged in a "cross" shape.

The tapered portion 52 is connected to the cylinder body 51, a first connecting hole is provided on the tapered portion 52, a second connecting hole is provided on the pile holding frame 4, and the connecting piece is passed through the first connecting hole and the second connecting hole to realize the detachable connection between the guide cylinder 5 and the pile holding frame 4, and then the guide cylinder 5 of the corresponding size can be installed on the pile holding frame 4 according to the pile foundation of different sizes to ensure the accuracy of the pile foundation piling construction.

[0063] Exemplarily, one of the first connecting hole and the second connecting hole is a threaded hole, and the other is a through hole; the connecting member is a bolt or a screw commonly used in the art.

[0064] Furthermore, a plurality of stoppers 6 are provided between the side wall of the cylinder 51 and the side wall of the fixed channel 40. The stoppers 6 may be Figure 5 The stiffening ribs shown in the figure are in contact between the cylinder 51 and the fixed channel 40 to fix the guide cylinder 5 in the fixed channel 40; or the stopper 6 is as shown in the figure. Figure 6 The flexible member shown is sandwiched between the cylinder 51 and the fixed channel 40. In addition, the side of the flexible member that abuts against the side wall of the fixed channel 40 is provided with an oblique opening.
