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 u

Example Embodiment

[0036] Example one:

[0037] A method for installing a stable pile positioning platform, A. Install multiple GPS mobile stations 5 on the crane vessel 6;

[0038] B. Fit and fix the shipboard connecting edge of the outrigger 1 with the outboard edge of the crane vessel 6. The outrigger 1 is used to build a stable pile positioning platform, and the inner frame of the outrigger 1 and the engineering pile 3 is compatible with the outer diameter;

[0039] C detects and calculates the relative positional relationship between multiple GPS mobile stations 5 and the center point of the inner frame of the leg frame;

[0040] D. With reference to the relative positional relationship between multiple GPS mobile stations 5 and the center points of the inner frame of the outrigger, the coordinates of each GPS mobile station 5 corresponding to the coordinates of each GPS mobile station 5 are calculated based on the actual sinking center point coordinates of the engineering pile and the coordinates ...

Example Embodiment

[0047] Embodiment two:

[0048] On the basis of the first embodiment, the second embodiment is further improved. There are two GPS mobile stations 5, and the straight line obtained by connecting the centers of the two GPS mobile stations 5 is connected to the crane vessel 6. The outboard edges of the ship are parallel, and the distance between the two GPS mobile stations 5 is greater than the width of the stabilizing platform. The reason for this setting is that the lifting ship and the outrigger are two different objects, and when installed on the lifting ship, increase appropriately The long side distance between GPS mobile stations is beneficial to improve the positioning accuracy of the center of the outrigger frame and reduce errors.

[0049] As long as the relative position relationship between the two GPS mobile stations 5 and the center points of the inner frame of the leg frame is detected and calculated, the stakeout coordinates of the two GPS mobile stations 5 can be cal...

Example Embodiment

[0051] Embodiment three:

[0052] On the basis of the second embodiment, the third embodiment is further improved. After the step A, perform the step A':

[0053] A’1. Draw a horizontal line 4 perpendicular to the center line of the GPS rover at the midpoint of the center line of the GPS rover;

[0054] A’2. Lift and move the leg frame 1, and when the center point of the inner frame of the leg frame is on the horizontal line 4, perform step B.

[0055] The step A'is performed in order to more conveniently detect and calculate the relative position relationship between the two GPS rover stations 5 and the center points of the inner frame of the leg frame in step C. The center point of the inner frame of the leg frame is located on the horizontal line 4, that is, the distance from the center point of the inner frame of the leg frame to the two GPS mobile stations 5 is equal, The center point of the frame and the center points of the two GPS mobile stations 5 form an isosceles triangle,...

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...
