测量的完全控制job with Leica iCON soil compaction solution

作者：Arne Forsell

我们在瑞典Kristianstad以南的Tollarp的Peab现场办公室。森林郊区的一个围栏区域沿着篱笆放置了几个红色容器办公室。仓库，材料，机器和汽车充满了剩余的空间。这是一个充满活性的地方，它是PEAB新公路项目的核心。

“I think this is the best machine control system for soil compactors that is available today. We use it for almost all of our soil compactors, and we are very familiar with the solution. The Leica iCON compaction solution contains all the functions that we need,”says Fredrik Larsson, chief surveyor at PEAB.

拉尔森（Larsson）靠在椅子的座位上，看着工人的会议室。他考虑了墙上贴上的印刷建筑计划。一条绿线从一个计划到另一个计划作为蠕虫。它表明了拉尔森（Larsson）从事的项目已经工作了几年，他和他的同事期望在2020年圣诞节左右完成。该项目是塞塔尔·瓦（Sätaröd-Vä）E22高速公路的建设。

Everything is managed and controlled from here: the construction of a 16-kilometre-long double-tracked highway through fertile farmland in the southeast region of Sweden crossed by 26 different bridges and bordered by numerous stone fences that are removed and placed back again during the construction phase. The project involves extensive environmental considerations such as fragile surface watercourses that the project must protect during the construction process.

“I have full control of my work.”

You could call this project“在刀的边缘上工作，因为它包含许多潜力，但也可能引起许多涉及的负责人的汗水，”explains Larsson.

In his home in Hässleholm, located a 45 minutes’ drive away, he enjoys spending time with his family. If there is any free time left, he runs his mountain bike in the surrounding forests together with his friends from the cycling club.“I used to run a lot ofcycling tours when I was younger,”says Larsson, “but one day my knees put an end to that, and I have taken up cycling and mainly mountain biking since then.”对于从事大型重型建筑项目的人来说，这是一个很好的爱好。

在Highway Project E22的这一部分中，Larsson担任首席测量师，这项工作需要大量的检查和数据分析。但是拉尔森对他的工作充满信心，原因之一是因为他得到了Leica Icon土壤压实解决方案的支持。

Just as important as the heartbeat is for a human body, so is the compaction of the filling material in a construction project, it is essential. To have the complete insight into the various stages of the project and all the layers from the terrace and upwards, to see all the values and work with the data in real-time is of great importance, and Larsson can rely on the solution. He and his employees have tested several machine control solutions for compaction. Still, he knew that he had found the right solution when he was presented with the solution from Leica Geosystems, and he experienced that his ideas and requirements on how to fine-tune the solution were being heard.

“通过图标土壤压实，我可以完全控制自己的工作。很容易处理它。我们的任何人都可以与解决方案一起工作，并轻松overseethe workflows and find the weak spots in the compaction. All the values and data are registered by the soil compactor’s Compaction Meter Value Sensor and transmitted wirelessly. Everybody involved in the project can monitor the workflow in detail from theircomputers,”says Larsson.

Project E22 is the largest highway construction project since the construction of the bypass road around Malmö was completed in 2000. The budget for the project was around 67,000 million Euro, and for Larsson and his colleagues, it has involved earthmoving of 1 million cubic meters of material. A project of this scale requires the right technical equipment, and the chief surveyor on Project E22 has found it.

Larsson does not need to go to the physical construction site that often, and it is not because he is afraid of leaving the office chair and go out in the real world. He receives continuous updates on his computer on how the compaction process is going. The data is shown with colour codes. Every movement that the soil compactor makes is displayed, and the colour codes are reflections of the variation in soil stiffness. Exact measurement indications along the line show the exact location of weak spots, so you don’t have to look for them. This results in higher quality of the work and lower operational costs.

“看着at the results of using the solution,不难理解这对时间和成本节省的意义，”says Larsson.

It was easy right from the beginning

机器操作员Edis Mazlovic坐在振动土壤压实器上，这是12吨Dynapac CA 3500D，这要归功于他的工作，这要归功于他挡风玻璃右侧的清晰清晰的MCP80面板。他可以监视他所做的通行证，如何在机器下压实土壤，以及如何避免过度或下面的压实。Mazlovic可以在此过程的早期检测到弱点，并确保压实工作尽可能高效。数据将不断地实时传输到Larsson接收到的办公室。

“学习系统很容易，”says Mazlovic.“I have only worked with soil compactors for a couple of months, but I haven’t had any problems with the program. It was easy right from the beginning.”

图标压实解决方案制造的土壤中弱点的检测也改变了测试弱点的岩土技术人员的工作。现在，通过机器控制解决方案确定为弱的区域，仅需要进行两次压实测试。工作流程已经简化，从而节省了大量成本和时间。

Efficient, accurate, easy-to-use as well as cost-efficient. These are the keywords for the Leica iCON soil compaction solution, which is why chief surveyor at PEAB has found his favourite solution and dares to say:“该解决方案是市场上最好的！”
