摘要
文章介绍了在不扰动已经铺设完成的碎石基床条件下,实现水下高精度清除回淤物的装备及方法的设计思路,得出了在风、浪、流条件下,清淤系统运行稳定可靠,并结合工程情况找出了影响基床面清淤施工的关键参数。在外海深水条件下风、浪、流作用下,不扰动已铺设沉管碎石基床面的条件下,进行了基床面水下高精度快速清淤施工。为大型沉管碎石基床清淤施工提供了理论分析依据。
In this paper,the equipment and design ideas of achieving the high precision method for underwater silt removal under the condition of not disturbing the existing gravel bed were introduced. It was concluded that the dredging system was stable and reliable under the combined action of wind,wave and current. And the key parameters affecting the construction of gravel bed were found out. Under the combined wind-wave-current action,dredging system can dredge the silt quickly without disturbing the gravel cushion. The result provides theoretical basis for the gravel cushion dredging of immersed tube tunnel.
