Let it flow

水力发电是水为水燃料的明显能源。

The Santo Antonio Hydroelectric Plant is a domestic source of energy able toprovide electricity to about 45 million Brazilians。根据国际水力发电协会（IHA）评估，位于亚马逊的中心，是巴西的第四大工厂，可持续性排名第一。

To build a project of this endeavour, water needs to be enclosed with cofferdams to create a dry environment for the major construction work to proceed. Upon competition of the hydroelectric plant, Grupo Toniolo Company had thecritical task to remove the downstream cofferdamso the Madeira River could flow freely through the turbines to generate electricity.

为了达到水力发电厂的全部潜力，Grupo Tonilo Company有90天以去除33,000平方米的固体岩石，紧凑的土壤和组成Cofferdam的粘土。

With the commissioning of Consórcio Construtor Santo Antônio (CSAC), Grupo Toniolo geared up for this challenging project and set up the excavators with the Leica Geosystems 3D excavator machine control solution. The challenge of this project, however, didn’t only reside on the magnitude of the cofferdam’s volume – excavators had to be mounted on two barges to extract the material from the opaque waters of the Madeira River.

No more guesswork

Excavating with zero visibility through waterwith maximum performance and efficiency was possible for this project thanks to theLeica IXE3 3D系统。Instead of relying on the operators’ guess to remove the cofferdam material, the information on the iXE3 panel allowed the operator to know with total accuracywhere to dig and how deep.

“借助Leica的3D挖掘机控制解决方案，我们确切地知道Cofferdam在哪里以及从哪里开始删除材料。操作员got it right on the first time和easily achievedvery good resultsGrupo Toniolo的所有者JohnisToníolo说。“没有Leica的Icon IEX3，我们将无法运行此类项目。就像一个盲人再次看到。”

Based on the bathymetric survey of the riverbed channel provided by CSAC, Grupo Toniolo designed aCAD 3D model to guide the excavationas per the referenced design. With the iEX3 3D/2D panel view, operators had full information to operate the excavator and were also able to:

• 可视化精确定位of the cofferdam without external survey support. The iEX3 screen shows the operator the cut and fills areas in the colour map.
• Avoid overloading.The system tells the correct position of the bucket allowing blind and submerged cuts.
• 消除开挖。如果达到所需的深度，则控制面板屏幕中的颜色图更改为绿色

No more rework

根据3D CAD模型，可以在马德拉河中快速准确开挖，从而导致saving time and costs。消除年级检查和返工使公司可以完成这项复杂的工作准时。Additionally, the skilled team of operators just neededfew hours of training要开始操作挖掘机，没有任何外舱指示，请在棍子上标记或水位

“借助Leica的Icon IEX3解决方案，挖掘机的停机时间减少了50％，我们第一次完成了工作，因此不需要返工。使用该系统将我们的产量提高了40％，”GrupoToníolo生产工程师Frederico Martins说。

幕后

现场成功也取决于数据的准备，传输和处理。

TheLeica ConX和iCON office由3D挖掘机系统支持的解决方案启用了import and export of data from the office to the field和empoweredremote access from the field手术

Thanks to these software technology solutions Grupo Toniolo was able to:

• Control the progress on-site，检查操作小时，并使用Icon远程信息处理从其基地的数字模型更新数字模型(CONX).
• Verify and record excavation progress直接在机器屏幕和办公室上，带有图标远程信息处理（CONX).
• Share with their customerall on-site data, calculate volume analysis, and generate various reports with the use of iCON office.

敢digitalise

For this particular project, Grupo Tonilo dared to go digital with Leica’s 3D excavator machine control solution to以更快，更高效，更准确的方式自动化流程。

“By using Leica’s iCON iXE3 3D system, our company benefited for the first time from 3D CAD models and state-of-the-art GNSS technology to guide an excavator machine,”马丁斯说。与Leica的3D挖掘机控制系统的首次接触意味着完整new workflowfor Grupo Toniolo – from the design to the operation, this project represented aninnovationon how they do business.
