在Hinkley Point C中驾驶生产力

作者：迈克·詹姆斯

A belief in doing things better continues to drive innovation at Hinkley Point C (HPC), the first of a new generation of European Pressurised Reactor (EPR) nuclear power stations being constructed in the United Kingdom. This vision isn’t simply a throw-away statement but echoes from every corner of one of the largest construction sites in Europe and is ingrained in the makeup of its people.

为了在建设这个大型项目之前获得核心样本并建立安全的基础，岩土钻探was needed. Geared with Leica Geosystems solutions, HPCadapted cutting-edge geotechnical drilling- 英国的第一个方法学阶段是由朱利安·诺斯（Julian North）领导的，朱利安·诺斯（Julian North）是Kier Bam合资企业的前高级岩土工程师。

将机器控制引入岩土钻孔

Geotechnical drilling is performed before construction begins to prepare and analyse the site, determining soil stability and the geology of the site. Complex heavy construction works, like岩土技术钻井可从机器控制中受益匪浅， 哪一个显示和positions tools according to reference, allowing operators to position the bucket or blade between the target grade.

Having overseen the geotechnical drilling operations at HPC, from the early ground works investigation and instrumentation drilling through to the main ground installation, North understands thebenefits of digitalising operations with machine control,“我们研究了潜在的风险，以及如何使每个人都更好地使岩土技术钻探的传统方法 - 机器控制符合这种信念。”

北部发现，位置控制对岩土技术钻探至关重要在现场快速访问某些信息至关重要。“一个大优势是我们不需要进行地形调查。We can go in using an excavation model into an area where we may not have been able to excavate before,”解释了北。“Machine control saves vast amounts of engineering timE并确保更好地优化设备。”

North also highlighted the importance ofbenefits beyond machine optimisation,“健康和安全有一笔巨额的回报。大写遥控系统限制了大型设备的噪音，灰尘和危害的限制。”

针脚钻探以提高生产率

Stitch drilling is the process of钻一系列孔near one another (typically200至250毫米），造成一条弱点。使挖掘机更容易利用任何不连续性并撕掉完整的岩石。这项技术导致更快，更清洁的挖掘，最大程度地减少其余岩石质量的干扰。

Equipped withLeica Icon IRD3在两个钻机中的解决方案，操作员完成了超过40,000 linear metresof stitch drilling. North explained the benefits of this method,“随着岩石自然削弱，您可以使用较小的挖掘机，可用于更深的挖掘部分，在该挖掘中，较大植物的空间受到限制。”

As stitch drilling normally comprises the drilling of large numbers of shallow holes, any decrease in the time taken to set up the drill mast on individual holes had a减少完成指定区域所花费的整体时间的重要意义。指某东西的用途Leica Geosystems机器控制启用了钻机的设置mast at the correct orientation and position, bringing not only significant savings but also reducing labour and engineering resources.

北方目睹了如何well the machine operators adopted Leica Geosystems technology。“一旦他们使用了几天，那就是‘我不能回去。我不能做任何其他方式”。added North.“Themachine operators found the screen ideal for them to set the drill mast up。The engineers also loved it because they didn’t have to be out in a muddy site all the time, we could just drill in a line and didn’t have to worry about losing the finite positions.”

深入挖掘：发掘

指某东西的用途machine control allowed operators to do fewer drilling rigs more efficiently with less downtimewithout waiting for positions to be excavated or marked out. This efficiency released the drilling rigs to complete other drilling activities faster and with less supervision.

The complex components of deep excavation were made up of more than100个不同的施工平台，许多画廊，竖井和污泥。垂直岩石面的高度不到1 m至38 m,所以必须德西边界gned to allow for the difference in elevation.

“所有面孔均用现场生产的钢纤维增强的喷涂混凝土处理发掘的48小时内提供防止风化的保护，”解释了北。“Ground nails [metal bars] are then installed to provide global slope stability for surcharge loads that will be imposed by cranes.”

Geotechnical drilling and beyond

在HPC，数字构造，包括3D modelling of construction sites和visualising end-to-end construction project workflows是工具性的。“检查了Hinkley Point C的每项操作，以使其在安全，质量和生产率方面变得更好，”解释了北。

对于这个施工阶段，将钻机定位以在使用机器控制正确的方向和位置brought大量的时间和资源节省同时减少暴露于灰尘，噪音和设备危害。

根据北部的说法机器控制通过在整个项目周期中转换实践来驱动生产力，例如在斜坡上取出地面指甲，例如铁路插条。“You have avirtual site layout在机器控制系统中举行。也有控制仪器孔进行现场调查的巨大好处。有一个可以使用机器控制的巨大机会。”
