Description

Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaic power generation, in particular to a cross-pile anchoring structure for offshore suspended photovoltaics. Background Art

[0002] After years of research on offshore photovoltaic support structures, it has become an industry consensus to adopt large-span structures and reduce the use of pile foundations. Among large-span structures, cable-suspended structures have gradually developed into a new type of offshore photovoltaic structure with a broad application market due to their low steel usage, good economy, convenient construction, and short construction period.

[0003] Traditional offshore photovoltaic cable-stayed structures can be anchored with a single pile anchor structure or a precast concrete cap anchor structure. However, in a single pile anchor structure, due to the influence of water depth and wave factors, the pile foundation structure is often a high cantilever, and the top is subjected to a large horizontal force from the cable, which will form a large bending moment at the bottom of the pile foundation, resulting in the need for a large pile body section to resist the horizontal force on the top of the pile. The precast concrete cap anchor structure has improved bearing capacity compared to the single pile due to the use of inclined piles, but there are problems such as excessive concrete consumption, unreliable grouting structure, and complex construction procedures for connecting anchor points. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide a cross-pile anchoring structure for offshore suspension photovoltaics, which can solve the problems of large amount of concrete used and unreliable grouting structure in the existing inclined pile anchoring structure.

[0005] To this end, the utility model adopts the following technical solutions:

[0006] A cross-pile anchoring structure for offshore suspended photovoltaics includes a first anchoring pile and a second anchoring pile. The first anchoring pile is fixedly connected to a guide tube, the guide tube is obliquely inserted into the interior of the first anchoring pile, both ends of the wire tube are connected to the outside, and the second anchoring pile is arranged in the guide tube.

[0007] On the basis of adopting the above technical solutions, the present invention can also adopt the following further technical solutions, or use these further technical solutions in combination:

[0008] The upward end of the guide tube is located outside the first anchor pile, and the upward end of the guide tube is provided with a guide ring expanding outward from bottom to top, and the guide ring is funnel-shaped.

[0009] An annular limiting block is fixedly connected between the second anchor pile and the guide ring.

[0010] A through reserved hole is provided at the upper end of the first anchor pile, a pull plate is fixedly connected inside the first anchor pile, the pull plate is vertically installed and located in the middle of the reserved hole, and a hanging point is provided at the lower part of the pull plate near the reserved hole.

[0011] The position of the hanging point is higher than the lower end point of the reserved hole.

[0012] The plane where the pulling plate is located coincides with the plane of the inclination direction of the guide tube.

[0013] The upper end of the second anchor pile is higher than the upper end of the guide tube.

[0014] The second anchor pile is welded to the annular limit block, and the annular limit block is welded to the guide ring.

[0015] The hanging point is arranged on one side of the pull plate close to the lower end of the second anchor pile.

[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects: by setting a cross-pile anchoring structure, the horizontal bearing capacity is improved, the horizontal force on the anchoring structure is converted into the pressure of the second anchoring pile and the pulling force on the first anchoring pile, so as to maximize the bearing capacity of the pile body; the pile bodies are connected by welding, so as to reduce the amount of concrete used, and eliminate the offshore grouting process; the first anchoring pile is firstly sunk to ensure simple and accurate positioning; due to the setting of the guide pipe, the second anchoring pile is easy to install, and the same pile sinking mechanism as the first anchoring pile can be adopted, so as to avoid the problem of using special pile sinking equipment, save the cost of pile sinking construction, simplify the offshore construction process, improve the construction efficiency, and shorten the offshore construction operation time.
