一种有效卸载沙粒之平顶驳船(FTB)之卸载系统，包含：(i)一分隔结构，其将FTB之平台分割成复数个舱室，用于盛装沙粒以供卸载至一特定区域；(ii)喷射水管线，供位于每一个舱室之流态化的沙粒或颗粒状类材料用，加压水系经由喷射水管线而被引入至任何选择的舱室中，喷射水管线具有复数个喷嘴以产生泥浆沙粒以供藉由吸入之卸载用；以及一补充水管线以提供额外水给喷射水管线；(iii)吸入管线，具有一吸入支线，吸入支线具有吸入口，该吸入管线系形成于每一个舱室，藉以允许泥浆沙粒经由吸入管线被吸出以供卸载；(iv)一Jacuzzi水坑，形成在舱室之内，复数个Jacuzzi喷嘴形成在Jacuzzi水坑周围，以供区域化搅拌，以使沙粒维持悬浮；以及(v)一泵驳船，包含抽吸机构，其包含复数个安装于其上之喷射水泵、泥浆泵以及补充水泵，其中喷射水管线系连接至喷射水泵，吸入管线系连接至泥浆泵，而补充水管线系连接至补充水泵。本发明亦关于一种从平顶驳船卸载沙粒之方法。; (ii) jetwater line for fluidization of sand or granular like material at each of the compartments, pressurized water being introduced into any selected compartment via the jetwater line having a plurality of nozzles to produce slurrified sand for unloading by suction; and a make-up water line to provide additional water to the jetwater line; (iii) suction line having a suction branch with suction inlets, the suction line being formed at each of the compartments, allowing slurrified sand to be sucked out via the suction lines for unload; (iv) a Jacuzzi sump formed within the compartments, a plurality of Jacuzzi nozzles formed around the Jacuzzi sump for localized agitation to keep the sand in suspension; and (v) a pump barge comprising pumping means including a plurality of jetwater pumps, slurry pumps, and make-up water pumps mounted thereon, wherein the jetwater line is connected to the jetwater pumps, the suction line is connected to the slurry pumps, and the make-up water line is connected to the make-up water pumps. The present invention also relates to a method of unloading sand from flat top barge. |
