Offshore water area steel pipe pile lofting method
The invention discloses an offshore water area steel pipe pile lofting method which comprises the following steps: a, placing and fixing a positioning device near a steel pipe pile construction position; b, carrying out coordinate positioning on the positioning device by utilizing a total station; c, according to the relative position of the positioning device coordinates and the steel pipe pile lofting coordinates, the device rotation system angle and the first hydraulic telescopic rod telescopic amount are calculated; and d, the steel pipe pile is hoisted through the positioning device. According to the invention, the coordinates of the offshore wading steel pipe pile can be precisely lofted, so that the horizontal coordinate positioning precision and the perpendicularity positioning precision of the hoisted steel pipe pile are ensured. In the whole operation process, the total station only needs to be used for measurement twice, so that the steps of frequently adjusting the position of the prism and repeatedly using the total station for measurement to ensure the lofting precision in the traditional lofting process are omitted, and the lofting efficiency is improved. The positioning device has the function of adjusting the sag of the steel pipe pile and has high accuracy on horizontal coordinate positioning and perpendicularity positioning of the steel pipe pile.
本发明公开一种离岸水域钢管桩放样方法，包括离岸水域钢管桩放样方法，包括以下步骤：a、将定位装置摆放在钢管桩施工位置附近并固定；b、利用全站仪对定位装置进行坐标定位；c、根据定位装置坐标与钢管桩放样坐标相对位置计算装置转动系统角度和第一液压伸缩杆伸缩量；d、通过定位装置吊放钢管桩。本发明能够精准放样离岸涉水钢管桩的坐标，使得吊放钢管桩的水平坐标定位精度和垂直度定位精度得到保证。在整个操作过程中，仅需要使用2次全站仪测量，省去了传统放样中频繁调整棱镜位置，并多次使用全站仪测量以保证放样精度的步骤，提高了放样效率。定位装置带有钢管桩垂度调节功能，对钢管桩的水平坐标定位和垂直度定位具有较高精确度。
