Underwater positioning pile sinking system for jacket foundation and process of underwater positioning pile sinking system
The invention discloses a jacket foundation underwater positioning pile sinking system and process. The jacket foundation underwater positioning pile sinking system comprises a self-elevating platform, an upper guide pipe, a jacket foundation body, a lower guide pipe and a lifting assembly. Upper guide pipes are symmetrically arranged in a U-shaped opening of the self-elevating platform in a diagonal crossing mode, a jacket foundation body is horizontally arranged in the U-shaped opening of the self-elevating platform relative to the lower portions of the upper guide pipes, and lower guide pipes are symmetrically and horizontally arranged on the outer side faces of the periphery of the jacket foundation body in a diagonal crossing mode. The upper guide pipes and the corresponding lower guide pipes are vertically aligned, and guide blocks are horizontally clamped in the upper guide pipes and the lower guide pipes in the length directions of the upper guide pipes and the lower guide pipes; the jacket foundation body vertically moves up and down along a U-shaped opening of the self-elevating platform through the lifting assembly, and then after underwater positioning is conducted, guiding positioning is conducted on pile sinking of a steel pipe pile through matched use of the lower guiding pipe, the upper guiding pipe and the guiding block. According to the invention, rapid underwater positioning is realized, and the guiding precision is high.
本发明公开了一种导管架基础水下定位沉桩系统及其工艺，包括自升式平台、上部导向管、导管架基础本体、下部导向管和升降组件；在所述自升式平台的U型口内呈对角线交叉对称设有上部导向管，且在其U型口内相对于上部导向管下方水平设有导管架基础本体，并在导管架基础本体的四周外侧面呈对角线交叉对称水平设有下部导向管，上部导向管均与对应下部导向管上下对齐设置，且在上部导向管和下部导向管内还沿其长度方向水平卡接设有导向块；导管架基础本体通过升降组件沿自升式平台的U型口进行竖直上下运动，进而在水下定位后，通过下部导向管、上部导向管以及导向块的配合使用，对钢管桩沉桩进行导向定位。本发明实现快速水下定位，且导向精度高。
