让它流动

Hydropower is a clear source of energy fuelled by water.

圣安东尼奥水力发电厂是能够的国内能源来源向约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.

为了建立这项努力的项目，需要用Cofferdams封闭水，以创造一个干燥的环境，以进行主要的建筑工作。在水力发电工厂竞争之后，Grupo Toniolo Company拥有critical task to remove the downstream cofferdam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公司had90 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。IXE3面板上的信息无需依靠操作员的猜测去除COFFERDAM材料，使操作员可以完全准确地知道在哪里挖掘和深入。

“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。操作员第一次做到了并很容易实现很好的结果,” 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模型指导发掘根据引用的设计。借助IEX3 3D/2D面板视图，运营商拥有完整的信息来操作挖掘机，还可以：

• Visualise the precise positioning没有外部调查支持的围堰。这iEX3 screen shows the operator the cut and fills areas in the colour map.
• 避免过载。该系统告诉桶的正确位置，允许盲和淹没。
• Eliminate 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 in节省时间和成本。Eliminating grade checking and rework permitted the company to finish this complex jobon time。Additionally, the skilled team of operators just needed几个小时的训练to 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.

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，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。
• 验证并记录发掘进度直接在机器屏幕上和办公室，带有图标远程信息处理。
• 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 complete新工作流程对于Grupo Toniolo - 从设计到操作，该项目代表了一个创新关于他们如何做生意。
