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, thefoundation must be stabilised with concrete piles cast in the underground。

The Austrian construction companyHilti＆Jehleis contracted for the piling work, which will take approximately six months. Hilti&Jehle,自2013年以来使用机器控制, is using the Liebherr LRB355 machine, a versatile machine重105吨andreaching up to 33,5 metres。This powerful machineis equipped with the newLeica图标iRP3machine control solutionfor drillers and pilers from Leica Geosystems.

“We drill the outer casing into the ground. The auger in the middle removes the soil, then concrete, reinforced with iron casing is poured into the hole，” Hilti＆Jehle项目经理MarkusMähr解释说。

Thejob is also done a lot faster， 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。

“像这样的宽松土壤上使用数字图案的好处之一是，传统的喷雾标记在下雨时很容易丢失，当机器在现场工作时。当然，数字模式不是这种情况,” says Mähr.

Liebherr集成解决方案

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’delivery, where the machine is delivered with all cables from the Liebherr factory and with Liebherr’s own sensors.

“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,Leica Geosystems的技术支持Reto Bardill解释说。

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, which means the as-built information is directly exported to Liebherr’s own data recording and as-built reporting system.

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

Exploring new possibilities with Leica MC1

新软件，Leica MC1,为PILER钻机运营商提供更直观和图形的用户界面。可以为运行屏幕设置气缸视图因此，操作员有一个overview over the ready piles and the remaining ones。

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工具，Leica ConX, allowing users toshare, visualise and report data in real-time。Hilti＆Jehle使用CONX进行模型转移以及remote沟通。Bardill登录到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.
