Method for mounting pile-stabilizing positioning platform

Abstract

The invention discloses a method for mounting a pile-stabilizing positioning platform. The method includes the steps that A, multiple GPS moving stations are mounted on a floating crane; B, a ship board connecting edge used for constructing a supporting leg bracket of the pile-stabilizing positioning platform is attached and fixed to the ship board outer edge of the floating crane, and an inner frame of the supporting leg bracket is adaptive to the outer diameter of each engineering pile; C, the relative position relations between the GPS moving stations and the center point of the inner frame of the supporting leg bracket are detected and calculated out; D, lofting coordinates corresponding to each GPS moving station are calculated out through the coordinates of a center point of each actual engineering pile sinking position according to the relative position relations between the GPS moving stations and the center point of the inner frame of the supporting leg bracket; and E, the floating crane is moved until the actually-measured coordinates of each GPS moving station are consistent with the corresponding lofting coordinates. The method has the advantages that operation is simple, and positioning is accurate.

Description

technical field [0001] The invention relates to the field of engineering pile stabilizing piles, in particular to a method for installing a stabilizing pile positioning platform. Background technique [0002] When building foundation wind turbines in the middle of the river or on the seabed, it is necessary to sink a number of engineering piles to the bottom of the river or the seabed. At this time, the engineering piles must be lifted to the pile sinking point by hoisting first, and then the piles should be sunk. In order to ensure that the verticality of the pile body is within 3‰ during the process of inserting the engineering pile into the mud and driving the pile smoothly, it is often necessary to use the pile stabilization platform to stabilize the engineering pile. The pile-stabilizing platform generally includes outriggers. In the prior art, the outriggers are often fixed and built at the point to be built. The disadvantages are as follows: 1. On-site outriggers in o...

AI Technical Summary

Problems solved by technology

The pile-stabilizing platform generally includes outriggers. In the prior art, the outriggers are often fixed and built at the point to be built. The disadvantages are as follows: 1. On-site outriggers in offshore waters During construction, the construction is easily restricted by unfavorable conditions such as monsoons, gusts of wind, rainstorms, cold waves, sea fog, and swells. Especially in unsheltered offshore waters, the risk of on-site construction of outriggers is relatively high and the accuracy is difficult to grasp; 2. Adopt the method of fixing and building at the same time. If there is a problem of displacement of the outrigger during the construction process, the original part must be removed and re-built, which is cumbersome and inefficient; 3. The operation is complicated
