Pile holding frame, and high-rise pile cap foundation installation system suitable for very shallow water areas

Abstract

The invention relates to the technical field of wind power generation equipment, and specifically relates to a pile holding frame, and a high-rise pile cap foundation installation system suitable forvery shallow water areas. The pile holding frame comprises a base body, and several guide cylinders and negative pressure cylinders respectively arranged on the base body, wherein the negative pressure cylinders are located under the guide cylinders and arranged in a staggered form with the guide cylinders. In use, the pile holding frame provided by the invention is integrally fixed through the negative pressure cylinders, after the negative pressure cylinders fix the pile holding frame well, the guide cylinders can be used for installing steel piles and so on, thus, a positioning function forpile sinking in the high-rise pile cap foundation can be realized, and construction of the high-rise pile cap foundation is facilitated.

Description

technical field [0001] The invention relates to the technical field of wind power generation equipment, in particular to a pile holding frame and a high pile cap foundation installation system suitable for extremely shallow waters. Background technique [0002] At this stage, the development and construction of domestic offshore wind power is gradually entering the fast lane, and some offshore wind power projects need to face the problem of deep or even extremely shallow water (ships can only enter the construction site during the tide and need to sit on the beach for construction). Especially in some areas of offshore wind power geology, the soil cover layer is shallow and there are rock formations below. At present, for this geological situation with rock formations below, the most mature foundation solution for offshore wind power is the high pile cap foundation. [0003] However, the pile sinking of the high pile cap foundation in extremely shallow waters requires the us...

Problems solved by technology

The hull structure of traditional piling ships is single-layer bottom (that is, there is only one layer at the bottom of the ship). If the bottom of the ship is leaked by obstacles (such as rocks), the consequences will be serious, and it will cost a lot to transform it into a double bottom.

In addition, piling ships generally have a relatively deep draft, and some places with shallow water depths (about 2m) cannot take advantage of the tide to enter
