Let it flow

Hydropower is a clear source of energy fuelled by water.

这Santo Antonio Hydroelectric Plant is a domestic source of energy able to向约4500万巴西人提供电力。Located in the heart of the Amazon, this hydroelectric complex is the fourth largest plant in Brazil and No. 1 in sustainability as per the International Hydropower Association (IHA) evaluation.

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 the删除下游Cofferdam的关键任务因此，马德拉河可以自由流过涡轮机发电。

To reach the full potential of the hydroelectric plant,Grupo Tonilo Companyhad90 days to remove the 33,000 square metres of solid rock, compact soil and clay composing the cofferdam.

随着Consórcio约束者SantoAntônio（CSAC）的调试，Grupo Toniolo为这个具有挑战性的项目做好了准备，并使用Leica Geosystems 3D挖掘机控制解决方案建立了挖掘机。但是，该项目的挑战不仅属于Cofferdam的体积的大小 - 必须将挖掘机安装在两个驳船上，以从马德拉河不透明的水域中提取物料。

没有更多的猜测

通过水的零可见性挖掘由于这个项目，该项目的最高绩效和效率是可以的Leica iXE3 3D System。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 accuracy在哪里挖掘和深入。

“With Leica’s 3D excavator machine control solution, we knew exactly where the cofferdam was and where to start removing the material. The operators第一次做到了and easily achieved很好的结果,” said Johnis Toníolo, owner of Grupo Toniolo. “We cannot run this kind of project without Leica’s iCON iEX3 anymore. It is like a blind man seeing again.”

基于CSAC提供的河床通道的测深调查，Grupo Toniolo设计了CAD 3D模型指导发掘as per the referenced design. With the iEX3 3D/2D panel view, operators had full information to operate the excavator and were also able to:

• Visualise the precise positioning没有外部调查支持的Cofferdam。IEX3屏幕显示操作员的切割，并填充颜色图中的区域。
• 避免过载。该系统告诉桶的正确位置，允许盲和淹没。
• 伊莱minate over excavation.If the desired depth is reached, the colour map in the control panel screen changes to green

没有更多的返工

Allowing a rapid and accurate excavation in the Madeira River based on a 3D CAD model resulted insaving time and costs。伊莱minating grade checking and rework permitted the company to finish this complex jobon time。此外，熟练的运营商团队只需要few hours of trainingto start operating the excavator without any outside cabin indication, mark on a stick, or water level

“With Leica’s iCON iEX3 solution the excavator downtime was reduced by 50 per cent and we got the job done the first time so no rework was needed. Using this system increased our production by 40 per cent,”said Frederico Martins, production engineer at Grupo Toníolo.

Behind the scenes

Success on-site depends also on the preparation, transfer and processing of data.

多亏了这些软件技术解决方案，Grupo Toniolo才得以：

• 控制现场进度, check the operation hours, and update the digital models from their base in Curitiba with iCON Telematics（（ConX）。
• 验证并记录发掘进度directly on the machine screen and on the office with iCON Telematics (ConX）。
• 与客户分享所有现场数据，计算体积分析并使用图标办公室使用各种报告。

敢于数字化

对于这个特定项目，Grupo Tonilo敢于使用Leica的3D挖掘机控制解决方案进行数字化处理automate processes in a faster, more efficient and accurate way。

“通过使用Leica的ICON IXE3 3D系统，我们的公司首次从3D CAD模型和最先进的GNSS技术中受益于指导挖掘机机器，”said Martins. This first contact with Leica’s 3D excavator machine control system meant a completenew workflow对于Grupo Toniolo - 从设计到操作，该项目代表了一个创新on how they do business.
