监视克里斯蒂安斯塔德的中央污水处理厂
Case study
Author: Frederick Somerville
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。
To monitor ground movements, the measurement consulting companyMätrix AB在必须将桩驱动到地面时，使用Leica Geosystems的设备进行了监测测量。
距离克里斯蒂安斯塔德（Kristianstad）的治疗厂几百米处，瑞典的最低地点位于海平面2.32米处。“低水平意味着建筑工地的地面条件是瑞典最糟糕的情况之一，”测量顾问，MätrixAB的首席执行官兼创始人Evelina Nilsson说，位于Svängsta。
Because the ground conditions are so poor, nearly 1,500 concrete piles had to be being piled into an area where pipes and piping infrastructure already exists. When such extensive piling is performed, careful checks are required as mass movement in the ground can cause shifts and settlements in the surrounding areas. This can be devastating, racking up large costs and damages.
通过监视，结果高质量
“当我们收到测量分配时，我们评估了许多可能的解决方案，以如何执行监视。我们得出的结论是，与自动监测测量值相比，手动测量不会给出足够的全面结果，因为需要频繁的时间间隔和相对较长的时间内连续监测如此多的测量点。” Evelina解释说。
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 MS50total station, fourLeica 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 GeoMoSwhich controls the measurements and现在，Leica Geomos！to analyse the data.
In addition, a number ofLeica Nivel 220tilt sensors, were mounted on some of the worksite’s surrounding buildings to check for any effects. Being very sensitive sensors, with a tolerance of 0.0047 mm/m, the Nivel 220 gives very early indications if something is happening to the inclination of the buildings on which they are mounted.
“Initially, we measured in the same way around the clock, but when the piling work turned out to be causing too much disturbance in the total station measurements, we chose during the day to only use the tilt sensors. We set them up such that they sent across movement data every three minutes and the tilt sensors provided results and sounded alarms if something was happening outside the limit values” says Evelina.
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。”
What has been the result of monitoring?
“测量结果表明，地面上有动作，但它们是易于管理的，并且不像最初所担心的那样大。但是，如果我们没有进行这些测量，那么没有人会确定并只能做出假设。得益于测量，有可能以受控的方式进行打桩，这也使每个人都感到安全并控制了情况。”
监视测量结果产生的数据也高质量，并提供了很多信息。
“With manual measurement, we were able to measure all points but could only repeat the cycle a few times whereas with automated monitoring, we were able to make many measurements of the same points every night” says Evelina.
现在在Geomos的帮助下！软件，所有捕获的数据都可视化。
“With GeoMoS Now!, graphs and reports can be easily created for everyone involved in the project and used as the basis for a good analysis. This allowed us to come up with improvement proposals and the geo-technicians could also review the data before making any decisions.”
为客户节省了成本
测量的具体和积极作用是可以验证从一开始投射的打桩方法。如果地面移动了很多，可以使用另一种更昂贵的打桩方法。得益于自动监控结果，这得到了避免，从而阻止了成本的增加。
节省成本的另一个例子是确保一条大型1200毫米线，就像颈动脉一样，将所有水从治疗厂的一部分运送到另一部分。
“如果由于定居点而损坏了基础设施，那将是一场灾难，整个工厂都必须关闭。现在，我们的测量可以遵循运动，并表明这种风险不存在。”
屡获殊荣的创新者和年轻测量咨询公司
Mätrix AG is a young company founded by Evelina Nilsson in 2014 when she was just 23 years old. Today, it has five employees and is in the process of recruiting two more. In 2020, Mätrix came in third nationally in the Young Entrepreneurs of the Year competition; organised by the trade association Företagarna.
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。
“客户服务非常重要，我们不断考虑客户的需求。我们希望在传统行业中发挥创新性，并始终努力以正确的质量，正确的范围和正确的时间提供服务。她说：“我们在工作和彼此紧密合作，集思广益的解决方案，想法，并在需要时不断支持。”
Like the accuracy
Mätrix works mainly with measurement assignments in building production and construction projects with concrete; meaning housing, real estate, industrial buildings and sports facilities.
“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（客户服务软件包）支持协议。
“We have chosen to buy everything from Leica Geosystems not only because the equipment is of the highest quality but also because they maintain a very high level of service. I think they have a unique personal approach and they always want to give their utmost to us as a customer, regardless of whether it is about finding new solutions, taking care of support matters or complexities to provide the fastest possible help on site.”
您会继续监视测量吗？
“监视测量在瑞典正在上升。Many believe that projects must be large for it to be useful but I see that there is great added value even in smaller projects” says Evelina. “It is clearly a service that we at Mätrix AB will want to develop further. It is a good complement in the field of control measurement and that is very exciting.”
