具体实施方式
为了使本领域技术人员更好地理解本发明的技术方案，下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
如图1-4所示，本实施例中提供了一种船舶支撑工装，具体包括由上到下依次接触设置的墩木1、沙箱2和水泥坞墩4，其中墩木1位于沙箱2顶部，而沙箱2位于水泥坞墩4的顶部，沙箱2与墩木1、水泥坞墩4之间接触设置，所述沙箱2与所述墩木1之间还设置有沙箱盖3，所述沙箱2内用于填充的固体沙料，沙箱盖3能够随沙料高度下降或上升；每个所述侧面板22上均设置有不少于一个的矩形孔221，矩形孔221上设置有侧封板26用于在填充沙料时防止沙料流出，侧面板22上位于矩形孔221的两侧分别设置有第二加强板25；侧封板 26位于两第二加强板25之间；并通过插接在第二加强板25上的所述插销27固定。所述侧封板26通过第二加强板25与插销固定能够便于侧封板26后期打开。
需要说明的是，矩形孔221的数量根据需要设定，当墩木长度为1.8m时，矩形孔数量一般为一个，此时第二加强板25设置在侧面板22的中部，而第一加强板24设置在两个第二加强板25的远离其相对另一个第二加强板25的两侧，但是当墩木长度大于2m时，矩形孔221数量可以为两个或者更多，此时第二加强板25与第一加强板24间隔设置。
上述沙箱2包括底板21、设置在底板21上的两侧面板22以及两端面板23，两所述端面板23相对设置，且两所述侧面板22相对设置，每个所述端面板23均与两侧面板22可拆卸式连接，具体为端面板23插接在两侧面板22之间。其中，每个所述侧面板22上均设置有第一加强板24、第二加强板25。设置第一加强板24以及第二加强板25的目的在于增强侧面板22的强度，当沙料填充在沙箱中时，沙料被夯实的过程中会给侧面板22挤压力，而设置有第一加强板24和第二加强板25的侧面板22则能够承受挤压力，增强该沙箱2的使用寿命。
本实施例中，为了能够便于将端面板23从侧面板22上拆除，所述侧面板22两侧还设置有插销耳板29(参考图3)，所述插销耳板29上设置有用于将端面板23与所述侧面板22紧固连接的插销27。
本实施例中还包括链条28(参考图4)，所述链条28用于将端面板23、侧面板22分别与插销27连接，进而能够防止插销27掉落的情况下不会丢失。
如图5-7所示，沙箱盖3包括沙箱盖顶板34、位于沙箱盖顶板34靠近所述沙箱2的一侧的沙箱盖中间腹板31、位于沙箱盖中间腹板31远离所述沙箱盖顶板34的一侧的沙箱盖底板32，所述沙箱盖中间腹板31侧面上还设置有多个沙箱盖肋板33。其中，沙箱盖3的沙箱盖中间腹板31与沙料接触的一端的面积小 于沙箱2靠近沙箱盖3一端开口面积，该种设置方式能够使所述墩木1与所述沙箱盖3相互接触的侧壁小于所述沙箱盖3与所述墩木1相互接触的侧壁。如图7所示，沙箱盖中间腹板31与沙箱盖顶板34相接触的一端的面积大于另一端远离沙箱盖顶板34的面积，沙箱盖中间腹板31横截面为梯形；或者还可以是沙箱盖中间腹板31两侧开设有凹槽用以减小沙箱盖中间腹板31底端的面积；沙箱盖顶板34四周还设置有沙箱盖侧板35。
上述船舶支撑工装安装步骤如下：
先放置水泥坞墩4，然后放置沙箱2，将侧封板26安装在在矩形孔221的位置处，使用第二加强板25和插销27将侧封板26紧固；将端面板23插于侧面板22两端，使用插销耳板29、插销27紧固，然后将沙料(一般是建筑沙料)填充于沙箱2的箱体内，并夯实；然后将沙箱盖3放置于沙箱2的正上方，然后根据船舶分段外底板与沙箱盖3的距离，放置合适厚度的墩木1，并打紧墩木1，此时船舶支撑工装完成安装。
本实施例中还提供了一种拆除墩木的方法，应用于本实施例中提供的船舶支撑工装；该方法具体包括：将侧封板26、和端面板23从沙箱2中拆除，然后使用高压水柱从端面板23拆除处冲水使沙料流出，沙料流出到能够使沙箱盖3随沙料减少而下降的量时，停止冲水；当墩木1与船舶分段外底板21脱离接触后，将墩木1移出，完成墩木1拆卸。
当然，当侧封板26不存在时，只需要去除端面板23即可。
上述方法能够快速的实现墩木下降，进而能够实现非破坏性拆卸墩木，使拆卸后的墩木能够重复使用，节约成本。
通过将当需要拆除墩木1时，将插销27从第二加强板25和插销耳板29中取出，然后将侧封板26和端面板23取出，然后使用高压水柱往沙箱2两端面 冲水或者从矩形孔221处冲水，使沙料(即黄沙)流出，一定量的沙料流出后，停止冲水，此时沙箱盖3整体随着沙料的减少流出而下降，最上方的墩木1也随着沙箱盖3的下降而下降，墩木1从而与船舶分段外底板脱离接触，即可用人力用锤子敲击将墩木1移除。
注意，以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施方式的限制，上述实施方式和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内，本发明的要求保护范围由所附的权利要求书及其等效物界定。
