Description
Technical Field
The utility model relates to a steady pile platform, especially a stable pile frame of seat bottom pile inserting formula single pile.
Background
Wind energy is a renewable clean energy, and wind turbines are generally adopted to collect wind energy in the prior art. Due to the large amount of space available in the sea and the high wind power, more and more wind farms are built offshore. The wind turbine generator set in the prior art mostly adopts a single-pile structure, the single-pile foundation structure is the current mainstream offshore wind turbine foundation structure type in the world and the country, the single-pile foundation in the country mostly adopts a transition flange-free structure, the verticality requirement of a single pile is extremely high, and therefore pile stabilizing equipment is required to be adopted to assist pile sinking when the single pile is installed, so that the verticality requirement of the pile is met. There are many different types of pile-stabilizing platforms in the prior art, and for example, chinese patent publication No. CN207829001U discloses a pile-stabilizing positioning platform for offshore wind power single-pile foundation, which includes: the pile feeding port is arranged at the bow part of the main platform; the pile embracing mechanism is arranged at the bow part of the main platform and is matched and connected with the single pile foundation; the pile punching system is arranged on each platform pile leg; each lifting system is correspondingly arranged at the joint of one platform pile leg and the main platform; the two rudder propeller systems are arranged at the stern part of the main platform; four sets of anchor winches are symmetrically arranged at the fore/aft positions of the port and the starboard of the main platform. The pile stabilizing and positioning platform positions the single pile through the pile feeding port on the main platform, and because only one main platform is arranged, when the lower part of the single pile is subjected to water flow impact and other factors to be cut obliquely, the single pile feeding port cannot effectively play a limiting role, so that the verticality of single pile installation is influenced; and taking and placing the single pile through the pile feeding port is troublesome; meanwhile, a plurality of other mechanisms are arranged on the pile stabilizing positioning platform, and due to the corrosivity of seawater, the pile stabilizing positioning platform needs to be maintained frequently, so that the maintenance cost is high.
In the prior art, a wind power deepwater underwater jacket is mostly adopted to build an offshore wind power generator set, a foundation steel pipe pile of the underwater jacket type fan is constructed by sinking a pile by using a hydraulic hammer, and the elevation control deviation of the pile top is large. Under the conditions that the water depth is deeper and the sea condition is worse, the pile position deviation of the hydraulic hammer pile sinking is larger. In the marine piling process, due to the fact that the construction area is wide, the working face is large, the construction environment and the weather condition are poor, pile position deviation control cannot meet requirements according to a conventional measurement positioning mode. If no special construction process and control measures are adopted, the relative position error of the pile top cannot meet the design requirement. In order to ensure that the pile sinking precision of the underwater steel pipe pile meets the requirements, a complete pile sinking control process must be developed to control the pile sinking of the steel pipe pile.
