Description

TECHNICAL FIELD [0001] The present invention relates to a jig for pile foundation construction including marine green energy generation and a marine foundation structure construction method using the jig for pile foundation construction,

The present invention relates to a foundation structure for wind power generation or solar power generation and a construction method of a bridge foundation structure. More particularly, the present invention relates to a construction method for a foundation structure of a bridge, The present invention relates to a jig for the construction of a pile for green energy generation and a construction method of a marine foundation structure using the jig for facilitating the connection of the foundation file and the jacket by arranging the foundation file on the sea level.

Recently, as the problems of depletion of natural resources and environmental and stability of thermal power and nuclear power generation have been raised, studies on wind energy and solar energy, which are representative green energy, are actively underway.

Generally, a wind turbine generator that generates electricity using wind is constructed so that a blade (or a propeller) is installed on a rotary shaft of a generator to generate power by using rotational force generated by the rotation of the blade by the wind. Such a wind turbine is a device for converting wind energy into electric energy, usually composed of a blade, a transmission, and a generator, and rotates a blade of a wind turbine, and generates electric power by rotating the blade.

Here, the blade is a device for converting wind energy into mechanical energy by being rotated by the wind, and the transmission device transmits the rotational force generated by the blade to the transmission gear through the central rotation axis and increases to the rotation speed required by the generator, The generator is a device that converts the mechanical energy generated by the blade into electric energy.

Such a wind power generation system is easy to operate and manage because it is simple in its structure and installation, and can be unmanned and automated. In the past, wind power structures were mainly located on land, but due to problems such as wind resource capacity, aesthetics, and location constraints, it is in recent trends to build a large scale wind farm on the sea. However, in order to construct a wind turbine structure safely at sea, a safe installation method for a blade and a tower structure to be installed in a high position is required.

In other words, such a wind turbine system is a system configured to convert kinetic energy by wind into electrical energy, and can be divided into onshore and offshore depending on the environmental conditions to be installed. In addition, there are various methods for installing such a pile or pile, such as a pneumatic type, a hydraulic pressure type, a drilling type, and a suction type. In order to install a large diameter pile or a pile,

In order to achieve the target and desired power in such a wind turbine installation, it is the role of the tower and support structure to place the nacelle capable of generating wind power at a predetermined height. These wind towers have steel pipe type and precast concrete type.

The offshore wind power generation structure is roughly divided into a turbine and a support structure. In this case, the support structure is typically a concrete caisson type, a mono-pile type, Jacket type, Tripod type and Floating type are applied in many cases.

The mono file type is the most widely used offshore wind turbine foundation method, and it can be installed at a depth of 25 ~ 30m. It is applied to Horns Rev and North Hoyle offshore wind farms. It is used to fix large diameter piles on the sea floor by hammering or drilling. Mainly it is less than 3Mw of wind power generator, If the condition is good, the economy is good. At this time, the base diameter of the monofile type is often 3 to 5 m.

The jacket type is currently being shown with great interest in the countries with offshore wind farms, and can be installed at a depth of 20 ~ 80m. These jacket types are supported by a jacketed structure and secured to the sea floor by a pile.

Such a jacket type is applicable to various depths of the ocean, has a high performance and high reliability, and is advantageous in that it is economically advantageous when used in a large-scale complex composition like the monophasic type described above.

On the other hand, there is a problem that it is difficult to control the position of the marine support structure due to the influence of waves, algae, etc., when the marine support structure according to the related art, for example, , There is a problem that the construction time is delayed due to a lot of trial and error in order to place the sea support structure at a predetermined position on the sea floor.

Jack-up pants are used as another construction method of the support structure.

In this method, the marine support structure is transported to the installation area using the pants for transport and is mounted on the seabed surface by a plurality of attempts. In order to fix the support structure mounted on the sea floor to the foundation file, Grouting is performed on the connection portion of the structure.

In this case, when grouting is performed on the connection portion between the foundation pile and the support structure, the support structure must be fixed to the large jackup pants for securing the verticality of the support structure, and the support structure to the grouting curing portion must be large jack- It must remain fixed to the crane installed in the crane. That is, the large jack-up pants were fixed on the sea, the marine support structure was placed on the fixed hinge, and the support structure was installed slowly using the crane.

As described above, if difficulty is encountered in controlling the position of the marine supporting structure due to waves, tides, etc., the marine installation work period may be prolonged, Renting costs can be excessive.

In the case of Korea, since the West Sea coast where the government intends to construct a large scale offshore wind farm, the legs of the jack-up pants must be intruded into the soft ground in order to secure the support of the jack-up pants during marine work, When pulling out the legs of the jack-up pants, the safety of the jack-up pants will be lost and the danger of overturning will increase. Therefore, it is very important to minimize the overhead load on the jack-up pants and to take care of lifting the heavy items such as wind power generators and towers.

Patent Document 1 (Japanese Patent Application Laid-Open No. 10-2014-0050186) discloses a method of manufacturing a wind turbine, including: a component transporting step of transporting a turbine, a blade, a tower, and a file of an offshore wind power generator; A file connecting step of inserting a file into the sleeve of the tower; And a file installation step of fixing the file inserted in the sleeve unit to the bottom of the sea. In the sea, only files can be connected to an upper structure assembled on the land, so that installation of an offshore wind power generator However, it is necessary to consider the special manufacturing cost of large-scale jack-up pants and to fix and draw out the jack-up leg due to the weight of the whole body including the wind generator, tower, and sleeve. It is very difficult to secure the workability and stability on the soft ground. In addition, due to the nature of the jack-up pants, it is not possible to secure the horizontal accuracy of itself, and a separate device must be installed to secure the vertical position when piling. On the other hand, when the wind power generator is transported to the target point, the entire wind power generator must be fixed to the jack-up pants and a separate fixing device is required. However, the jack-up pants must be able to withdraw from the file There is a problem that the fixing device bound with the jack-up pants can not be installed under the wind power generator.
