Steel pipe pile construction system and process based on floating pile stabilizing platform

Abstract

The invention discloses a steel pipe pile construction system and process based on a floating type pile stabilizing platform. The steel pipe pile construction system comprises the floating type pile stabilizing platform, a floating type crane ship, a split truss, a compensator and a steel pipe pile. An auxiliary crane is arranged in the middle of the upper surface of the floating pile stabilizing platform, and a main crane is arranged on one side of the upper surface of the floating crane ship. A plurality of compensators are symmetrically arranged on the head side and the tail side of the floating pile stabilizing platform at intervals on the left side and the right side, the compensators are horizontally arranged in the length direction of the U-shaped opening of the floating pile stabilizing platform at intervals, and the adjusting ends of the compensators face the center direction of the corresponding U-shaped opening. The two split trusses are arranged at the corresponding U-shaped openings of the floating pile stabilizing platform correspondingly and horizontally placed on the corresponding compensators correspondingly. And the split truss positioning operation, the steel pipe pile sinking operation and the split truss recycling operation are sequentially carried out through double-crane cross matching of the main crane and the auxiliary crane. An assembly line work mode is formed, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of offshore wind power, in particular to a steel pipe pile construction system and process based on a floating pile stabilization platform. Background technique [0002] Existing wind turbine foundations mostly use a single floating crane ship and a single pile stabilization platform, but a single project generally involves pile stabilization platform positioning, steel pipe pile turning over, steel pipe pile hammer pile sinking, and pile stabilization platform recovery Waiting for operation, this just causes can't realize assembly line operation, and work efficiency is lower. [0003] In addition, the leveling of steel pipe piles generally adopts the method of manual theodolite observation and directing the hydraulic cylinder of the pile stabilization platform to correct; since the theodolite cannot be erected on the floating crane, it can only be erected on the pile stabilization platform, but the pile stabilization...

AI Technical Summary

Problems solved by technology

[0002] Existing wind turbine foundations mostly use a single floating crane ship and a single pile stabilization platform, but a single project generally involves pile stabilization platform positioning, steel pipe pile turning over, steel pipe pile hammer pile sinking, and pile stabilization platform recovery And other processes, which makes it impossible to realize the assembly line operation, and the work efficiency is low

[0003] In addition, the leveling of steel pipe piles generally adopts the method of manual theodolite observation and directing the hydraulic cylinder of the pile stabilization platform to correct; since the theodolite cannot be erected on the floating crane, it can only be erected on the pile stabilization platform, but the pile stabilization platform is affected during the construction process. The impact of vibration is more, so the erection of the theodolite must be completed during the hammering period of the piling hammer, and the theodolite measurement should be erected after the hammer is stopped; moreover, the correction data of the hydraulic cylinder are estimated manually, and the accuracy is poor
