Description
Technical Field
The utility model relates to a marine large-scale artificial floating island and platform field, especially a marine city platform mooring system.
Background
A lot of marine urban groups are urgently needed to be built in the south China sea. One of the important factors of ocean currents is whether to successfully construct an offshore city group, and under the condition of storm, the horizontal thrust of the ocean currents to the offshore city is very large, the mooring and positioning mode of the traditional ship or ocean platform cannot stably and safely realize the mooring and positioning of the offshore city,
in the south sea area, coral reefs are numerous, reef plates formed by the coral reefs are calcified by dead bone of live corals, the main component is calcium carbonate, and the surface hardness of the calcium carbonate is lower than that of rocks but is greatly higher than that of gravel and soil. After the surface of the coral reef is broken, the bottom of the coral reef is not provided with bedrock, so only friction piles can be driven, but the coral reef hardly has tension on the surface of the pile, namely the pile fixing capability is poor, so that the conventional slide pile is formed, so that if a common friction pile is adopted as an anchoring structure at the sea bottom, the conventional slide pile is difficult to be qualified for strong horizontal thrust of a marine city,
in order to better construct an offshore urban platform, a method or apparatus that can solve the above problems is urgently needed.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit is applicable to the marine city platform mooring system of coral reef dish anchor.
The technical solution of the utility model is that: an offshore city platform mooring system, characterized in that: the system comprises a plurality of steel cylinder piles 1 surrounding a reef disc, each steel cylinder pile 1 is connected with at least two anchor chains 2, the other ends of the anchor chains 2 are connected with the inner sides of square offshore urban platforms 3, anchor connection points between the anchor chains 2 and the offshore urban platforms 3 are uniformly distributed,
Compared with the prior art, the utility model, have following advantage:
the offshore city platform mooring system with the structure is simple in structure, ingenious in design and reasonable in layout. It is poor to traditional friction stake solid stake ability when bottom reef dish is the coral reef, the problem of easy swift current stake, design out a special construction's steel cylinder stake, this steel cylinder stake is behind pouring expansion cement, expansion cement can drive its inside a plurality of steel cone needles outwards stinging, and prick on the coral reef, utilize these steel cone needles of embedding in the coral reef to form powerful frictional force, thereby guarantee that the steel cylinder stake can connect firmly on the reef dish, the phenomenon of swift current stake can effectively be prevented from appearing. The steel cylinder pile is matched with a plurality of anchor chains to be anchored in the square offshore urban platform, so that the mooring and positioning problems can be well solved.

Fig. 2 is a schematic structural diagram of a steel needle assembly part in the embodiment of the present invention.
Fig. 3 is a schematic view of the connection state of the steel cylinder pile and the reef disc in the embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1, 2, and 3: a mooring system of an offshore city platform comprises a plurality of steel cylinder piles 1 surrounding a reef disc, each steel cylinder pile 1 is connected with at least two anchor chains 2, the other ends of the anchor chains 2 are connected with the inner side of a square offshore city platform 3, anchor connection points between the anchor chains 2 and the offshore city platform 3 are uniformly distributed,
The utility model discloses marine city platform mooring system's working process as follows: firstly, a plurality of steel cylinder piles 1 are driven around a coral reef disc, the number and the specific distribution condition of the steel cylinder piles 1 can be determined according to the actual conditions of the shape, the size and the like of the reef disc, and the method can be realized by a person skilled in the art; after all the steel cylinder piles 1 are constructed, at least two anchor chains are arranged on the steel cylinder piles, the other ends of all the anchor chains 2 are connected with the inner side of the square offshore city platform 3, and all the anchor nodes need to be uniformly distributed in consideration of stability.
When the steel cylinder pile 1 is constructed, firstly, a cylinder barrel part of the steel cylinder pile 1 penetrates through a coral reef, then expansion cement is poured into a cavity inside the steel cylinder pile 1, the expansion cement can generate huge outward expansion force when being solidified, the expansion force pushes all steel cone needles 6 to slide in a needle base 5, conical pointed parts 7 of all the steel cone needles 6 penetrate out of through holes 8 and are embedded into the coral reef, and after limiting parts 9 on the steel cone needles 6 are contacted with steps 10, the steel cone needles 6 cannot continue to advance; after the expansion cement is solidified, all the steel conical needles 6 on the steel cylinder pile 1 extend out, and the steel conical needles 6 are in contact with the surrounding coral reefs in the circumferential direction, so that the steel cylinder pile 1 and the coral reefs are firmly and stably connected.
