每个所述分腔体的出口的形状均为圆形。
所述腔体二3具有四个侧壁，每个侧壁均为下部向内凹陷的弧形结构，并在连接处 圆滑过渡。
所述腔体二3的前后两个侧壁的上端间距与下端间距的比值为1.81～2.19。

所述腔体二3的前后两个侧壁的下端切向与竖直方向的夹角均为0°～9°，所述腔体二3的左右两个侧壁的下端切向与竖直方向的夹角均为0°～9°。
所述腔体二3的正上方具有腔体三4，所述腔体三4与腔体二3相连通。
本实施例的具体结构和装配详述如下：
如图1～4所示：一种工程船舶用砂水混合装置1，包括腔体一2、腔体二3、输送管道一27、输送管道二28、输送泵一33、输送泵二34、输送泵三35和输送泵四36；所述腔体一2和腔体二3相连通，腔体一2位于腔体二3的正下方。
腔体一2分为左右对称设置且相互独立的四个分腔体，左侧有两个分腔体，右侧有两个分腔体，当左侧砂源供料时，左侧的两个分腔体用于砂水的混合；当右侧砂源供料时，右侧的两个分腔体用于砂水的混合。
所述腔体一2顶部具有四个入口，即入口一17、入口二18、入口三19和入口四20，所述腔体一2底部具有四个出口，即出口一13、出口二14、出口三15和出口四16；所述入口一17与入口二18的几何尺寸相同，所述入口三19与入口四20的几何尺寸相同。所述入口一17和入口三19的几何形状可以为矩形，也可以为非矩形，例如圆形或者其他多端弧组成的形状，本实施例优选为矩形。所述入口一17、入口二18、入口三19和入口四20的几何形状均为矩形。
所述入口一17正对着出口13，所述入口二18正对着出口14，所述入口三19正对着出口15，所述入口四20正对着出口16。所述入口一17的面积大于出口13的面积，所述入口二18的面积大于出口14的面积，所述入口三19的面积大于出口15的面积，所述入口四20的面积大于出口16的面积，便于砂料的下落和汇集。
所述腔体一的出口一13和出口三15分别通过连接管一23和连接管三25与输送管道一27连接，并互相连通，所述腔体一的出口二14和出口四16分别通过连接管二24和连接管四26与输送管道二28连接，并互相连通；所述输送泵一33位于输送管道一27的入口端，所述输送泵二34位于输送管道二28的入口端，所述输送泵三35位于输送管道一27的出口端，所述输送泵四36位于输送管道二28的出口端。
所述腔体一的出口的形状和连接管的形状对应，连接管一23、连接管二24、连接管三25和连接管四26均为短管，四个连接管横截面的形状可为圆形，也可以为矩形、椭圆形或者其他形状，本实施例优选横截面为圆形的管。所述出口一13的形状为圆形，所述出口二14的形状为圆形，所述出口三15的形状为圆形，所述出口四16的形状为圆形。
所述连接管一23具有阀门一29，所述连接管二24具有阀门二30，所述连接管一 25具有阀门三31，所述连接管一26具有阀门四32。阀门的作用是根据施工的需要进行砂料混合输送的调节。关闭阀门一29，则砂料无法通过连接管一23，这样当砂源量较小时可仅通过一个入口(例如入口三19)进行施工。当砂源量较大时，可两个入口(例如入口一17和入口三19)同时参与施工。同理，左侧的两个入口(入口二18和入口四20)参与左侧的砂水混合作业。
所述腔体一2的入口一17和入口三19在工程船舶的右侧，作业可以在工程船舶的右侧进行，砂料通过所述腔体一2的入口一17和入口三19，然后分别通过连接管一23和连接管三25进入到输送管道一27，在输送泵一33和输送泵三35的作用下进行高效的砂料运送。所述腔体一2的入口二18和入口四20在工程船舶的左侧，作业可以在工程船舶的左侧进行，砂料通过所述腔体一2的入口二18和入口四20，然后分别通过连接管二24和连接管四26进入到输送管道二28，在输送泵二34和输送泵四36的作用下进行高效的砂料运送。能够实现工程船舶两侧的砂料独立作业，增加了施工多样性。
腔体二3为上大下小形式的腔体，所述腔体二3具有侧壁一5、侧壁二6、侧壁三7和侧壁四8四个侧壁，所述侧壁一5为弧形结构，所述侧壁二6为弧形结构，所述侧壁三7为弧形结构，所述侧壁四8为弧形结构。腔体二3的四个侧壁均是弧形结构，利于砂料的下落。当砂料落在侧壁一5、侧壁二6、侧壁三7或侧壁四8时，由于弧形侧壁的结构，砂料在重力作用下快速下落。
所述侧壁一5与侧壁四8的上端间距与下端间距的比值为1.81～2.19，所述侧壁三6与侧壁三7的上端间距与下端间距的比值为1.21～1.39，这样能够保证腔体二3具有一个存储砂料和下落砂料的良好的性能。优选地，当入口五21为矩形形状时，所述侧壁一5与侧壁四8上端的间距基本上就是入口五21的长度，所述侧壁三6与侧壁三7上端的间距基本上就是入口五21的宽度；所述侧壁一5与侧壁四8下端间距基本上就是腔体二3的出口或者腔体一2的入口(入口一17和入口三19长度之和、或入口二18和入口四20的长度之和)的长度，所述侧壁三6与侧壁三7的下端间距基本上就是腔体二3的出口或者腔体一2的入口(入口一17和入口三19宽度之和、或入口二18和入口四20的宽度之和)的宽度。
所述腔体二3的正上方具有腔体三4，所述腔体三4与腔体二3连接，并互相连通。砂料通过腔体二3的上端的入口五21进入到腔体二3，根据施工需要分别进入到所述腔体一2的入口一17、入口二18、入口三19或入口四20，也就汇集到腔体一2中。
砂料通过腔体三4上端的入口六22进入到腔体三4中，然后通过腔体二3的上端的入口五21进入到腔体二3中，实现了砂水的“第一次混合”，然后通过腔体一2的入口一17、入口二18、入口三19和入口四20进入到腔体一2中，实现了砂水的“第二次混合”。砂水混合物进入到输送管道一27和输送管道二28后，在输送泵一33、输送泵二34、输送泵三35和输送泵四36的联合作用下进行高效的输送。
一般地，砂料中可能夹杂有部分黏性颗粒，存在一定的黏附力。当砂料下落困难时，大部分的砂料存储于腔体二3中，砂料以出口中心(出口13、出口14、出口15或出口16)为轴呈现出漏斗状的砂料坡面，砂料坡面与侧壁(侧壁一5、侧壁二6、侧壁三7或侧壁四8)之间就会“滞留”大量的砂料，换言之，砂料下落缓慢，大部分砂料长期存储于腔体二3中，只有少量的砂料能够到达出口(出口13、出口14、出口15或出口16)。本实用新型的弧形侧壁(侧壁一5、侧壁二6、侧壁三7和侧壁四8)能够打破这种静力平衡，砂料因为侧壁的弧形角度原因而不能附着于侧壁(侧壁一5、侧壁二6、侧壁三7和侧壁四8)，也就便于了砂料的疏通和下落。
腔体二3的所述侧壁一5下端切向与竖直方向的夹角为0°～9°，所述侧壁四8下端切向与竖直方向的夹角为0°～9°，所述侧壁二6下端切向与竖直方向的夹角为0°～9°，所述侧壁三7下端切向与竖直方向的夹角为0°～9°，四个侧壁均为弧形结构。弧形结构使得砂料的疏通更加容易，也避免了砂料长期存储于腔体二3中而产生透水困难的问题。本实用新型的弧形侧壁能够让更多的海水参与砂料的混合，以形成良性循环，从而解决了砂料的堵口现象。
与现有技术相比，本实用新型采取前后输送泵(输送泵一33、输送泵二34、输送泵三35和输送泵四36)提供了砂水混合物的水力补偿，输送泵一33和输送泵二34用于提供大量的海水，提供了“送”的水力。
右侧的海水从吸入口一37进入输送泵一33，然后在所述输送泵一33的泵出口一41获得更大的水流速度，然后进入输送管道一27，从连接管一23和连接管三25中下落的砂水混合物被加速，通往所述输送泵三35的所述吸入口三39，在所述输送泵三35的再次加速作用下，砂水混合物在泵出口43获得更大的流速。
左侧的海水从吸入口二38进入输送泵二34，然后在所述输送泵二34的泵出口二42获得更大的水流速度，然后进入输送管道二28，从连接管二24和连接管四26中下落的砂水混合物被加速，通往所述输送泵四36的所述吸入口四40，在所述输送泵四36的再次加速作用下，砂水混合物在泵出口44获得更大的流速。
输送泵三35和输送泵四36提供水力“加油站”，让输送管道一27和输送管道二28中的砂水混合物的速度增加，超过水的携带泥沙速度，使得本实用新型的运送砂料的能力大大提高。
另外地，由于本实用新型的弧形侧壁结构，砂料下砂能力十分显著，砂料的运送能力也会提高。当下砂量过大时，还可使用阀门一29、阀门二30、阀门三31和阀门四32的调节功能，达到一个合理的送砂效果。
本实用新型的工程船舶用砂水混合装置1，具有砂料储存的能力，每次砂源供给可以将砂料存储于腔体二3中，部分砂料存储于腔体一2中，通过阀门一29、阀门二30、阀门三31和阀门四32的调节功能保证了施工送砂连续性。在相邻两次砂源供给期间， 在输送泵一33、输送泵二34、输送泵三35和输送泵四36的作用下，腔体二3中存储的砂料依然可以高效的输送，提高了施工的连续性。
现有的砂水混合装置每次砂料供给都需要精确的定位砂料的料口，让所述料口在入口六22的控制范围内。为减少了砂料供给的料口(砂源砂料的出口)定位时间，本实用新型的工程船舶用砂水混合装置的所述侧壁六10的与侧壁七11的间距基本上等于工程船舶的船宽，砂料从所述料口进入所述工程船舶用砂水混合装置1的入口六22，在供给过程中需要时刻保持所述料口和所述入口六22的配合变得更加容易，料口定位时间能够显著缩短，减少每次砂源的供给时间，从而提高了施工的效率。
由于采用上述技术方案，与现有技术相比，工程船舶用砂水混合装置能够增加砂料的混合流畅性能，减少砂料堵口现象，实现工程船舶的连续性作业。能够实现工程船舶两侧的砂料独立作业，增加了施工多样性。能够提供砂水混合物的水力补偿，减少了料口定位时间，同时本实用新型具有显著的砂料储存功能，提高了砂料的输送效率，并且结构简单，能够明显地减少材料成本和人工成本。
以上所述仅是对本实用新型的较佳实施例而已，并非对本实用新型作任何形式上的限制，凡是依据本实用新型的技术实质对以上实施例所做的任何简单修改，等同变化与修饰，均属于本实用新型技术方案的范围内。
