Deep stabilisation with cast-in-situ piling

作者：Karina Lumholt

In the small village of Aalen in the south-west of Germany, Palm Paper Factory GmbH is building a new paper factory on sanded ground. The project will be finished in 2022 and will contain heavy paper machines in a large building complex. Therefore, the基础必须稳定在地下的混凝土桩。

The Austrian construction companyHilti＆Jehle为打桩工作签约，大约需要六个月。Hilti＆Jehle，working with machine control since 2013，正在使用Liebherr LRB355机器，这是一台多功能机器重105吨和达到33,5米。这台功能强大的机器is equipped with the newLeica Icon IRP3machine control solution适用于Leica Geosystems的钻探器和桩。

“我们将外壳钻进地面。中间的螺旋钻去除土壤，然后用铁壳加固的混凝土倒入孔中,” explains Markus Mähr, project manager at Hilti&Jehle.

The工作的速度也更快， 感谢iRP3’s automatic navigation function。MarkusMähr估计它们是able to pile over 40 piles a day compared to only 30 piles without machine control。

“One of the benefits of using a digital pattern on loose soil like this is that traditional spray markings are easily lost when it is raining and when the machines are working on the site. This is of course not the case with a digital pattern”Mähr说。

A Liebherr-integrated solution

The machine in Aalen is an example of a machine control solution from Leica Geosystems integrated with Liebherr’s own sensor configuration. This is an example of a ‘左撇子’交付，在Liebherr工厂和Liebherr自己的传感器中，机器与所有电缆交付。

“The advantage of having a machine delivered ‘Leica-ready’, is that we can install the machine control solution and then have a fully operational machine within only two hours,” explains Reto Bardill, technical support from Leica Geosystems.

The integration between the Leica Geosystems machine control solution from and the Liebherr piler machine goes even further. TheLeica iRP3 interfaces directly with Liebherr’s Process Data Recording system，PDE，这意味着截止的信息直接导出到Liebherr自己的数据录制和构建的报告系统。

“Installingthe iPR3 solution to the piler was actually recommended by Liebherr,” explains Mähr.

Exploring new possibilities with Leica MC1

堆积为建造新工厂的柔软地面稳定。

新软件，Leica MC1,offers the piler rig operator a more intuitive and graphical user interface。The run screen can be set up forcylinder viewso the operator has an概述现成的桩和其余的桩。

作为Leica Geosystems提供的完整解决方案的一部分，Leica MC1现在支持基于云的合作tool,Leica Conx, allowing users to实时共享，可视化和报告数据。ConX is used by Hilti&Jehle for model transfers, as well as forremote沟通。Bardill登录to ConX from his office in Switzerland to the panel on the machine in Germany for remote training, troubleshooting and communication.

“钻机的新机器控制解决方案提供了新功能，支持Iredes，KOF和LandXLM文件格式，并具有新的，用户友好的3D接口，Leica Conx，” explains Petter Heyerdahl, product manager for rig solutions at Leica Geosystems.
