Pile sinking construction method for fixed arm type frame crane ship

Abstract

The invention discloses a pile sinking construction method for a fixed arm type frame crane ship. The pile sinking construction method comprises the following steps that S1, the crane ship travels to be close to a construction machine position, and anchoring and positioning are conducted; S2, a guide pipe frame transport ship correspondingly loaded with a guide pipe frame and a single pile transport ship travel to be close to the construction machine position, anchoring and positioning are conducted to be parallel, and the guide pipe frame transport ship, the single pile transport ship and the crane ship are arranged in a T shape; S3, the guide pipe frame is hoisted to the position below the mud face of the construction machine position through the crane ship to be fixed; and S4, the single pile is hoisted to the guide pipe frame through the crane ship, and pile inserting and pile sinking construction are conducted. The fixed arm frame type crane ship is adopted as construction hoisting equipment, an existing common hoisting ship is fully utilized, and the input cost is saved; anchor point coordinates of the crane ship and the transport ships are calculated and planned according to the specific position of the construction machine position, ship positioning errors are prevented, and the construction operation efficiency is improved; the levelness of the hoisting guide pipe frame is measured in real time, the guide pipe frame is adjusted in time to keep horizontal, the vertical accuracy of subsequent pile sinking is improved, and the pile sinking operation efficiency and precision are improved; and the coordination of the overall construction process is good, the construction process is safe, and the operation efficiency is high.

Description

【Technical field】 [0001] The invention belongs to the technical field of offshore wind power engineering, and in particular relates to a pile sinking construction method of a fixed arm type crane ship. 【Background technique】 [0002] The wind power on the ocean is fast, making full use of ocean wind resources to generate electricity can provide a part of the city’s electrical energy and relieve the city’s power supply pressure. The construction of wind power projects on the ocean is complicated and difficult. The single pile foundation is one of the most common structures for offshore wind turbine foundations. First, the current construction is difficult and the efficiency is low. The construction of offshore wind farms is too slow, and the efficiency is not directly proportional to the investment. 【Content of invention】 [0003] In order to solve the existing problems in the background technology, the present invention provides a pile sinking construction method of a fixe...
