监视Kristianstad’s central sewage treatment plant
案例分析
作者：弗雷德里克·萨默维尔
为了使Kristianstad能够增长并满足未来的需求，必须进行市政中央污水处理厂的重大重建和扩展。在正在进行的基金会作品中，存在一些挑战。例如，其中一个是，由于该地区以前是干燥的湖泊，因此工厂中的大多数现有管道和下水道都非常松散。
为了监视地面运动，测量咨询公司MätrixABperformed monitoring measurements with equipment from Leica Geosystems during the period when piles had to be driven into the ground.
A few hundred meters from the treatment plant in Kristianstad stands Sweden's lowest ground point at 2.32 meters below sea level. “The low level meant that ground conditions at the construction site are one of Sweden's worst”, says Evelina Nilsson, measurement consultant, CEO and founder of Mätrix AB, which is based in Svängsta.
由于地面条件是如此差，因此必须将近1,500块混凝土桩堆积到一个已经存在的管道和管道基础设施的区域。当执行如此广泛的堆积时，需要仔细检查，因为地面上的质量运动可能会导致周围地区的转移和定居点。这可能是毁灭性的，增加了巨大的成本和损失。
High quality in the result through monitoring
“当我们收到测量任务,evaluated a number of possible solutions for how the monitoring could be performed. We came to the conclusion that manual measurements would not give a sufficiently comprehensive result as compared to automated monitoring measurements because so many measurement points needed to be monitored continuously, at frequent intervals and for a relatively long period of time” Evelina explains.
在与Leica GeoSystems的Geomatics技术支持的Frederick Somerville咨询后，根据该系统创建了定制的监视解决方案Leica Nova MS50总站，四个Leica Viva GS14Mätrix已经拥有的GNSS天线，这是一种用于数据传输的新雷卡（Leica Combox）和软件Leica Geomos控制测量和Leica GeomosNow!分析数据。
另外，许多Leica Nivel 220倾斜的传感器安装在一些工作地点的周围建筑物上，以检查任何效果。Nivel 220是非常敏感的传感器，耐受性为0.0047 mm/m，如果发生了安装在上面的建筑物的倾向，则会给出很早的迹象。
“最初，我们以相同的方式进行测量，但是当桩工作在整个电台的测量中引起太多干扰时，我们在白天选择只使用倾斜传感器。我们将它们设置为使它们每三分钟发送一次移动数据，并且如果限制值之外发生的事情发生，则倾斜传感器会提供结果并发出警报。” Evelina说。
她补充说：“多亏了解决方案，我们能够满足客户对准确性的要求，并获得自动化的每日报告。”
监视的结果是什么？
“The measurements showed that there were movements in the ground but that they were manageable and not as large as was initially feared. If we had not performed these measurements however, no one would have known for sure and could only have made assumptions. Thanks to the measurements, it was possible for the piling to be carried out in a controlled manner, which also left everyone feeling secure and in control of the situation.”
监视测量结果产生的数据也高质量，并提供了很多信息。
伊维利娜说：“通过手动测量，我们能够测量所有点，但只能重复几次周期，而通过自动监测，我们每晚都能对同一点进行许多测量。”
With the help of the GeoMoS Now! software, all captured data is visualised.
“现在有了Geomos！，可以轻松地为参与该项目的每个人创建图形和报告，并用作进行良好分析的基础。这使我们能够提出改进的建议，而地理技术人员也可以在做出任何决定之前审查数据。”
Saved costs for the customer
A concrete and positive effect of the measurements was that the piling method projected from the beginning could be verified. There was an alternative, more expensive piling method that could have been applied if the ground moved a lot. Thanks to the automated monitoring results, this was avoided, thus preventing any increase in costs.
Another example of saved costs was the securing of a large 1200 mm line which, like a carotid artery, transports all the water from one part of the treatment plant to another.
“If there had been damage to the infrastructure due to a settlement, it would have been a disaster and the entire plant would have had to shut down. Now our measurements could follow the movements and show that that risk did not exist.”
屡获殊荣的创新者和年轻测量咨询公司
MätrixAg是一家年轻的公司，由Evelina Nilsson于2014年成立，当时她只有23岁。今天，它有五名员工，正在招募另外两名员工。2020年，Mätrix在年轻的年轻企业家比赛中排名第三。由贸易协会Företagarna组织。
该公司以高水平的知识，创新和一流的服务来介绍自己。Evelina年轻时从事服务贸易的工作，因此在她身上脱颖而出。
“Customer service is very important and we constantly think about our customers' needs. We want to be innovative in a traditional industry and always strive to deliver services with the right quality, the right scope and at the right time. We have fun at work and work closely with each other, brainstorming solutions, ideas and constantly support each other when needed”, she says.
喜欢准确性
Mätrix主要从事与混凝土建筑生产和建设项目的测量分配；意思是住房，房地产，工业建筑和体育设施。
“我们进行了许多精确的测量，并使自己对精度特别重要且需要一些额外思考的任务感到不安。就我个人而言，我认为这是最有趣的，需要额外的时间才能使一切正确。这确实满足了我的秩序感。”伊夫琳娜说。
Mätrix使用的所有测量设备来自Leica Geosystems，它们也有一个CCP (Customer Care Packages)支持协议。
“我们选择从Leica Geosystems购买所有东西，这不仅是因为设备的质量最高，而且还因为它们保持了很高的服务水平。我认为他们有一种独特的个人方法，他们总是希望将自己的最大程度地献给我们作为客户，而不管是要找到新的解决方案，照顾支持事项还是复杂性，以在现场提供最快的帮助。”
您会继续监视测量吗？
“瑞典的监测测量正在上升。许多人认为，项目必须很大才能有用，但我看到即使在较小的项目中也有巨大的价值。” Evelina说。“这显然是我们在MätrixAB希望进一步发展的服务。这是控制测量领域的一个很好的补充，这非常令人兴奋。”
