超越3D机器控制：集成的桩解决方案

作者：Reka Vasszi

The use of pile dwellings and deep foundation techniques to construct houses around the Alps date back to 5000 BC. Prehistoric settlements were built on wooden piles on the edges of lakes, rivers or wetlands. Only in Switzerland, there are 56 archaeological sites where these settlements and ancient construction techniques are exceptionally well-preserved.

Since prehistory, the technology has evolved, tools and machines for piling became larger, more efficient thanks to automation and positioning technology. Deep foundations are vital in many construction projects to strengthen the soil that will support the weight load of the building erected on top of it. When ground conditions are wet, or the project is planned above water, driven piles are crucial for the foundation of a new building.

This is when the Swiss construction company's piling expertise, Birchmeier Spezialtiefbau AG, comes in handy when working on the foundation of a new building for the water police on the shores of Lake Zürich.

Converting a boathouse to a water protection police station

苏黎世的水上警察确保该地区的24小时救援服务，寻找水下的人和物体，保护水免受油和化学物质的影响，管理船上摊位并维护港口。现有的建筑物和60年前建造的船屋将在2022年让位于当代的新建筑中，水警察和环境犯罪专家团体可以共同努力。

新的水上警察局位于一个著名的湖边，与1930年代相邻的受保护的历史建筑。因此，市政当局发起了一项建筑竞赛，以找到与邻近历史建筑相匹配的最佳设计，可持续并符合功能要求。

The jury was impressed by the project called "Coray" with its very clear and compact structure, including a boathouse, offices and a helicopter landing pad on top of the building. Due to the wet ground and weight load of the planned building, Birchmeier Spezialtiefbau AG was contracted to secure the deep foundation of the site.

Integrated technology is key to prepare for the job

Choosing pile foundations were ideal in the case of the new water police station. The waterside building is constructed to allow water underneath for easy access to the boats. In order to start the construction project, more than 150 piles were required to stabilise the ground.

Andreas Gassmann as foremen and Michael Fuchs as pile operator from Birchmeier Spezialtiefbau AG ensured that each pile is at the right location, at the right time.

Fuchs is working as pile operator at Birchmeier Spezialtiefbau AG for 3 years now. He is very fortunate to work on this project as he has the most comfortable seat and the best view over the lake of Zürich from his Liebherr 355 piling rig. Each morning together with Gassmann, they start with site inspection and overview of the daily tasks.

Once Fuchs aligned with the team, he turns on his Liebherr piler installed with the最新的Leica图标IRP3 3D机器控制解决方案. For accurate positioning, he checks the connection to the correction service is on as always. The corrections are needed for precise location and are handled by the machine control panel to the entire system. After the connection is checked, he loads the latest 3D model directly from the office to the machine control panel via the cloud solution,Leica ConX.

机器控制技术，精确的位置数据以及与办公室工作人员通过云的无缝集成使现场团队的每日工作变得更加容易，更快，更高效。

通过3D机器控制节省5分钟

当操作员在驾驶室中完成咖啡时，将3D计划加载到机器控制解决方案中，将位置数据固定，并且可以使用桩机。由于Fuchs正在使用3D机器控制技术，因此他不需要额外的团队成员在现场放置并检查桩的确切位置。

“在使用机器控制之前，我们与一家测量公司合作，找到需要将桩驱动到地面的位置，”福克斯说。“If the markings on the site were removed or disappeared, we had to wait again to recreate those points. With machine control, we always have an updated 3D plan on the panel that automatically guides me to the right location with centimeter accuracy."

通过使用3D机器控制，不仅桩的位置是准确的，而且不需要返工或等待出现。因此，Birchmeier Spezialtiefbau AG可以节省现场一个人的费用。

“With the 3D system, I can save at least 5 minutes per pile, which takes a lot at the end of the day with 20 piles,"reports Fuchs. "但是，通过机器控制，它也变得更加舒适，更容易，更安全。当使用如此大的机器和重堆工作时，周围人民的安全非常重要。现在，我可以相信机器控制的准确性可以指导桩毛的位置，我可以更多地关注其他方面，例如压力较小的安全性。”

测量，检查和验证GNSS智能天线

Swiss precision means: measure, check and verify. In the meantime, Fuchs is working with the piling machine; Gassmann double checks if each pile is in the right location with hisLeica Icon GPS 70 GNSS智能天线according to the plans hanging on the wall in his small field office.

“我最喜欢的产品是GPS Rover，”工长说。“我在GPS控制器上的3D计划与FUCHS在他的机器控制面板上的计划相同。我检查并验证地面上的每个堆，并越过计划中准备好的堆。”

在他以前在建造建筑中的角色中，他使用了莉卡（Leica Icon）GPS漫游者，以快速而精确的利益。由于该团队正在使用3D机器控制技术，因此Gassmann不再需要为操作员的桩子放置桩的位置。他们可以相信3D系统的准确性。

“Working with machine control means time savings and accuracy, which automatically leads to costs savings，”加斯曼说。“I love both products: the gps and machine control; it helps us to get the job done right for the first time,"summarises the foremen.
