宁波地区广大贫下中农,创造了不少水上施工工具,其中效果较好的是适用于深水拋石的象山大塘港漏底船和适用于浅水抛石的奉化红胜海塘蝴蝶船。这两种水上抛石船都具有结构简单,操作方便,造价低,工效高的特点,不仅能加快工程进度,而且抛石较准,船身较稳,有利于掌握施工质量和安全。现简介于下:一、漏底船:漏底船系木制结构,用人工操作,船身共分三舱,前后两舱是封闭舱,中舱是载荷舱,底部没有封闭(即漏底),用二扇活动铁栅门作为承载负荷。该船载重容量为10.5方,平均 The vast majority of poor and middle-income peasants in Ningbo have created a lot of tools for construction on the water. Among them, the better is the Xiangtan Datang Port Liner and the Fenghua Hongsheng Seashore Butterfly Ship suitable for shallow riprap. Both types of water riprap ships have the advantages of simple structure, convenient operation, low cost and high work efficiency, which can not only speed up the progress of the project, but also ensure that the riprap is accurate and the hull is stable, which is good for grasping the construction quality and safety. Now, briefly below: First, the bottom leakage vessel: leakage bottom of the Department of wooden structure, with manual operation, the hull is divided into three compartments, two compartments before and after the closed compartment, the cabin is the load compartment, the bottom is not closed ), With two activities grille gate as a load bearing. The ship carrying capacity of 10.5 square, average
