Description

Underwater measurement frame for foundation pipe pile of offshore wind power jacket

Technical Field

The utility model relates to a marine wind power equipment field specifically is a marine wind power jacket foundation pile's underwater measurement frame.

Background

At present, the offshore wind power technology gradually develops to a deep water area, and a foundation pipe pile used for supporting an offshore wind power jacket is gradually changed from a large-diameter single-pile foundation to a multi-pile jacket foundation. Because the actual pipe diameter and relative position of each jacket foundation pipe pile may deviate from the originally designed pipe diameter and relative position due to the influence of water pressure and geological reasons in the process of pouring the jacket foundation pipe piles, the relative position of the underwater jacket foundation pipe pile cannot be confirmed, particularly, seabed geological conditions in Guangdong and Fujian sea areas in China are complex, pile foundation engineering mostly involves weathered rock drilling construction, a 'drilling-drilling' process is usually required in the process of sinking the jacket foundation pipe piles, uncertainty and difficulty of foundation pipe pile construction are high, the actual position of the constructed jacket foundation pipe pile deviates from the originally designed position corresponding to the size of jacket supporting legs, and matching installation may not be performed after the jacket is transported in place. The weight of the whole jacket is very large, usually up to 800-. The transportation cost is greatly increased, the installation efficiency is reduced, and as the jacket has heavy weight and the height of 50-70 meters, the gravity center is very high, the jacket is very difficult to transport in a practical ship, and the jacket is easy to topple over when meeting strong wind, thereby bringing great potential safety hazards.

SUMMERY OF THE UTILITY MODEL

The utility model provides a simple structure, can the accurate measurement go out marine wind power jacket foundation pile's of jacket foundation pile relative position measure frame under water.

Offshore wind power jacket foundation tubular pile's underwater measurement frame, including a plurality of sleeves that correspond with each foundation tubular pile, connect as a whole through steel frame construction in the middle of each sleeve, be equipped with the hoist and mount piece that is used for hoist and mount at steel frame construction top, be equipped with a plurality of measuring orifices that are in same level on the not lateral wall of sleeve co-altitude, telescopic top still is equipped with the backup pad that makes the sleeve bearing in foundation tubular pile top.

Offshore wind power jacket foundation tubular pile's underwater measurement frame, before the installation jacket, through making the underwater measurement frame that the structure is simple relatively, weight is far below the jacket, hoist earlier and mount the underwater measurement frame to the foundation tubular pile on, its backup pad supports in the top limit of foundation tubular pile, the sleeve hangs in the foundation tubular pile, utilize the not co-altitude and the direction measuring aperture of seting up on the sleeve, measure the distance that the sleeve avoids to the foundation tubular pile, calculate out the relative position of each foundation tubular pile, the position and the size of actual measurement's foundation tubular pile before the jacket installation, thereby can be according to actual measurement preparation matched with jacket, make the jacket strictly accord with the assembly demand of foundation tubular pile, thereby ensure the jacket back of taking one's place, can be smooth insert the installation in the foundation tubular pile, the major accident of unable installation after having avoided the jacket transportation to target in place. And the foundation pipe pile measuring frame structure is only composed of the sleeve and the steel frame structure, the structure is simple, the size is small, the repeated use can be carried out, the gravity center is low, the offshore transportation loss can be greatly reduced, the offshore construction process is reduced, the construction cost is greatly reduced, and the method is safer, more economic and more efficient.

Detailed Description

As shown in fig. 1-4, an underwater measurement frame for offshore wind power jacket foundation pipe piles comprises a plurality of sleeves 1 corresponding to the foundation pipe piles, the sleeves are connected into a whole through a steel frame structure 2, a hoisting part 3 used for hoisting is arranged at the top of the steel frame structure, a plurality of measuring holes 4 at the same horizontal height are formed in the side walls of the sleeves at different heights, and a supporting plate 5 used for supporting the sleeves at the top of the foundation pipe piles is further arranged above the sleeves. Offshore wind power jacket foundation tubular pile's underwater measurement frame, before the installation jacket, through making the underwater measurement frame that the structure is simple relatively, weight is far below the jacket, hoist earlier and mount the underwater measurement frame to the foundation tubular pile on, its backup pad supports in the top limit of foundation tubular pile, the sleeve hangs in the foundation tubular pile, utilize the not co-altitude and the direction measuring aperture of seting up on the sleeve, measure the distance that the sleeve avoids to the foundation tubular pile, calculate out the relative position of each foundation tubular pile, the position and the size of actual measurement's foundation tubular pile before the jacket installation, thereby can be according to actual measurement preparation matched with jacket, make the jacket strictly accord with the assembly demand of foundation tubular pile, thereby ensure the jacket back of taking one's place, can be smooth insert the installation in the foundation tubular pile, the major accident of unable installation after having avoided the jacket transportation to target in place. And the foundation tubular pile measuring frame structure is only composed of a sleeve and a steel frame structure, has simple structure, small volume, low gravity center, capability of being repeatedly utilized, capability of greatly reducing the offshore transportation loss and the offshore construction process, greatly reduced construction cost, and higher safety, economy and efficiency.

The bottom of the sleeve is provided with a contracted conical pipe section 11 which can be used for better inserting the guide sleeve into the foundation pipe pile, so that the working efficiency is improved.

The conical pipe section 11 is fixed at the bottom of the sleeve in a welding mode, a plurality of rib plates are arranged on the inner side wall surface of the conical pipe section 11, the rib plates extend from the conical pipe section 11 to the position above the bottom of the sleeve and are welded with the inner wall of the conical pipe section 11 and the inner wall of the bottom of the sleeve, and the rib plates can increase the strength of the conical pipe section.

The backup pad is annular backup pad, and its top sets up a plurality of vertical reinforcing plates 6, and the reinforcing plate welds with backup pad and sleeve lateral wall simultaneously, increases the intensity between sleeve and the backup pad.
