Embodiment Construction

[0025] A method for accurately positioning pile sinking in open sea, the working process of which is as follows:

[0026] (1) Driving the first foundation pile through GPS positioning;

[0027] (2) Install a hydraulic internal expansion base 3 on the top of the first foundation pile 2, and automatically align the first pile through the actions of three sets of fully synchronized pile internal expansion hydraulic cylinders 5 on the hydraulic internal expansion base 3. The center position of the first foundation pile, and adjust the hydraulic internal expansion base to the horizontal state through the electronic level; Planar and mutually parallel laser ranging sensors 4, the lasers emitted by the laser ranging sensors 4 are on the same plane and parallel, refer to the attached figure 1 ,;

[0028] The working principle of the hydraulic internal expansion base is: taking the inner wall of the pile as the reference circle, three hydraulic oil cylinders installed at the corners ...

Abstract

Provided is an offshore sunken pile accurate positioning operation method. The offshore sunken pile accurate positioning operation method comprises the steps that (1) a first foundation pile is installed through GPS positioning in a driven mode; (2) a holder base which can carry out 360-degree rotation is installed in the center of the pile top of the first foundation pile, three laser distance measuring sensors which are arranged on the same plane and are parallel to one another are installed on the holder base, and lasers emitted by the laser distance measuring sensors are located on the same plane and are parallel to one another; (3) the actual position of a second sunken pile is found out through the three laser distance measuring sensors arranged on the first foundation pile, and the second sunken pile is installed in a driven mode; (4) the actual position of a third sunken pile is found out through the three laser distance measuring sensors arranged on the first foundation pile and three laser distance measuring sensors arranged on the second sunken pile, and the third sunken pile is installed in a driven mode; (5) accurate measurement of sunken piles in the whole engineering region is accomplished in an alternate mode. According to the offshore sunken pile accurate positioning operation method, real-time and accurate positioning can be carried out on the positions of the sunken piles, and site operators can have timely and accurate control over the positions of the sunken piles.

Description

technical field [0001] The invention relates to a pile sinking positioning process, in particular to an operation method for accurately positioning pile sinking in open sea. Background technique [0002] At present, the survey and positioning of open sea pile sinking far away from the coastline is based on GPS positioning technology. Because the accurate establishment of open sea reference stations is not easy to achieve, and the use of land reference stations due to the long distance, the signal received by the mobile station on the ship The error is large. Therefore, the measurement and positioning of the relative pile distance of pile sinking in the open sea far away from the coastline are generally realized by auxiliary positioning methods such as on-site cable control and positioning frame control. The disadvantage is that the measurement method is relatively primitive, the process is complicated, and it is not easy to realize when the relative pile distance is large. ...
