钢桩式抓斗船码头前沿施工技术

钢桩定位式抓斗船，由于其定位特点：占用施工水域小、避让影响小、定位精度高，广泛适用于开挖狭窄水域施工以及运营航道拓宽段施工。尤其在狭窄区域，其定位优势明显好于传统的锚缆式定位抓斗船。但抓斗船施工精度控制困难。结合工程实例，解决施工中出现的超深、施工安全以及施工质量等问题，结果比较满意，为工况相近的疏浚工程提供参考。

Wharf frontier construction technology of steel pile type grab dredger

The steel pile positioning grab boat,because of its positioning characteristics,such as small occupancy of construction waters,small impact of avoidance and high positioning accuracy,is widely applicable to the construction of the excavation narrow waters and the operation channel widening section.Especially in narrow areas, its positioning advantage is significantly better than that of the traditional anchor cable positioning grab ship.It is difficult to control the construction accuracy of grab dredger.Combined with engineering examples,the problems of ultra-depth,construction safety and construction quality in construction are solved,and the results are satisfactory and can be used as a reference for dredging projects with similar working conditions.
