Full control of the surveying job with Leica iCON soil compaction solution

Author:Arne Forsell

We are at PEAB’s site office in Tollarp south of Kristianstad, Sweden. A fenced area at the outskirts of the forest with several red container offices placed along the fence. Storehouses, materials, machines and cars fill up the remaining space. This is a place vibrating with activity, and it is the very heart of the new highway project PEAB is working on.

“我认为这是当今可用的土壤压实机的最佳机器控制系统。我们将其用于几乎所有的土壤压实物，并且对解决方案非常熟悉。Leica图标压实解决方案包含我们需要的所有功能，”PEAB首席测量师Fredrik Larsson说。

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。

一切都从这里进行管理和控制：建造了16公里长的双向高速公路，穿过瑞典东南部地区的肥沃农田，被26个不同的桥梁交叉，并被许多石栅栏边界，并在此期间再次拆除并再次放回原处。施工阶段。该项目涉及广泛的环境考虑因素，例如该项目在施工过程中必须保护的脆弱地表水道。

“我have full control of my work.”

你可以称这个项目“working on a knife’s edge because it contains a lot of potentials but can also provoke nervous sweating from many of the responsible persons involved,”解释说拉尔森。

在他在Hässleholm的家中，距离酒店有45分钟的车程，他喜欢与家人共度时光。如果剩下任何空闲时间，他将与自行车俱乐部的朋友一起在周围的森林中经营山地自行车。“我used to run a lot ofcycling tours when I was younger,”拉尔森说：“但是有一天，我的膝盖结束了这一点，从那以后，我开始骑自行车，主要是山地自行车。”It is a nice hobby for someone who works on large heavy construction projects.

In this part of the highway project E22, Larsson works as chief surveyor, a job that requires a lot of as-built checks and data analyses. But Larsson is confident in his work, and one of the reasons for that is because he is supported by the Leica iCON soil compaction solution.

与人体对人体的重要性一样重要，建筑项目中填充材料的压实也是必不可少的。要完全了解项目的各个阶段以及露台和向上的所有图层，以实时查看所有值并与数据一起工作非常重要，而Larsson可以依靠解决方案。他和他的员工已经测试了几种机器控制解决方案以进行压实。尽管如此，他仍然知道，当他从Leica Geosystems提供解决方案时，他已经找到了正确的解决方案，并且他经历了他对如何微调解决方案的想法和要求。

“With iCON soil compaction, I have full control of my work. It is so easy to handleit. Any of our foremen can work with the solution and easilyoversee工作流程并在压实中找到弱点。所有值和数据均由土壤压实器的压实表值传感器注册，并无线传输。参与该项目的每个人都可以从他们的computers,”says Larsson.

E22项目是自2000年Malmö周围旁路道路建设以来的最大公路建设项目。该项目的预算约为6.7亿欧元，对于Larsson及其同事来说，它涉及100万立方米的EarthMoving材料。这个规模的项目需要正确的技术设备，E22项目的首席测量师发现了这一点。

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.

“Looking在使用解决方案的结果中it is not hard to understand what it means for time and costs savings,”says Larsson.

It was easy right from the beginning

Seated on the vibration soil compactor, a 12 tonnes Dynapac CA 3500D, machine operator Edis Mazlovic has full control of his work thanks to the crisp clear MCP80 panel placed in the right side of his windscreen. He can monitor the passes he has made, how the soil has been compacted under his machine and how he can avoid over or under compaction. Mazlovic can detect the weak spots early in the process and ensure that the compaction work is done as cost-efficiently as possible. The data is continuously transferred in real time to the office where Larsson receives it.

“学习系统很容易，”says Mazlovic.“我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.”

检测土壤中的弱点de by the iCON compaction solution has also changed the work of the geotechnicians testing the weak spots. Only two compaction tests are now required on the areas identified as weak by the machine control solution. The workflow has been streamlined, resulting in significant costs and time savings.

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:“this solution is the best on the market!”
