摘要
码头清淤尤其是高桩码头平台下桩群间清淤是一个非常特殊的疏浚工程。金塘大浦口集装箱码头从开建至今,码头底下与码头前沿水深可差10 m以上。通过测量可知,码头底下淤厚达10 m以上,严重影响着桩群的安全,因此,急需寻找一合适有效的设备进行码头底下清淤。针对这种清淤设备国内缺稀、国外昂贵的情况,实验室利用自行研制的清淤设备深吸1型取砂装置在大浦口集装箱码头前沿进行清淤试验,为下一阶段码头底下清淤工程提供技术支持。
The wharf dredging is a very special kind of dredging project, especially under the high-piled wharf. The difference of water depth under the wharf and at wharf apron of Jintang Dapukou container dock is now above 10 m. It is known through measurement that the siltation under the pier is over 10 m, which seriously affects the safety of the pile group. Therefore it is urgent to find a kind of device to clear away the silt under the pier. In view of the situation that this device is uncommon in China at present and expensive to import from abroad, the lab carries out an experiment at the wharf apron with the self-developed device deep-suction I to provide technical support for the dredging engineering under the pier.
