在Esbjerg港工作的新挖泥传感器

作者：Karina Lumholt

Esbjerg Port, once the principal fishing harbour of Denmark, has today become the Danish capital of oil and gas and Europe’s leading port for shipping of off-shore wind turbines to the North Sea.

Esbjerg Community is currently extending the harbour with a new urban area and marina with the objective of giving the citizens better access to Esbjerg’s attractive marine and beach area. The new urban space will create close contact between the city centre and the harbour area and establish a centre for maritime leisure activities as well as new commercial and residential areas.

The plan is tocreate a new harbour lagoon with marina, new beach area, and eventually plan for a hotel and an art museum在新滨ar.

Machine control visualises the excavator’s work under water

VGEntreprenørA/S是一家在所有类型的沿海地区项目中具有专业知识的建筑公司，今年夏天开始从事该项目，并计划在2018年底终止。该公司已专门从事沿海保护以及港口和港口。安装。在Esbjerg港，他们的主要工作是在堤防和码头上进行挖掘和石头工作。ClausAggerSørensen担任该项目的每日经理。Claus准备图纸，订购石头，计算卷，分配资源并管理整体物流。

“Right now, we have four excavators working on the site and all of them are equipped with machine control from Leica Geosystems,”克劳斯解释了。“We used to use floats, buoys and stakes for measuring and controlling of the excavation under water. With machine control, it has become much easier when the actual digging under water is being visualised on the in-cabin panel.”

石垫的建造始于其层的绘图。Claus绘制AutoCAD中的配置文件。这些层由沙子或石头的核心，一层较小的滤清器，过滤织物和顶部的一层较大的石头组成。每一层都有一个配置文件文件，该文件被读取到图标Office软件中，它们将转换为3D型号，地形文件和行文件，然后将其读取到计算机上的机器控制解决方案中。这是通过基于Web的服务完成的Leica ConX.

“The Leica ConX tool makes it possible for me to on several projects at the same time,”says Claus.“I can help with a project that takes place in another part of the country at the same time as I am working here in Esbjerg.”

Claus还将使用工作的自动记录到create as-built documentation.

MSS420 dredging sensors

The construction of stone piers is a market niche for VG Entreprenør. It requires specialised machine operators who have the skills and experience to build all the layers and use the excavator to weave them together as a jigsaw puzzle.

For a couple of months, VG Entreprenør has worked with the newLeica MSS420挖泥传感器and has benefitted from the advantages of the new underwater application. The new dredging sensors have pressure tight connectors, robust stainless-steel sensor brackets and rugged cabling. This special design ensures a much longer lifetime of the sensors.

“We are working in a very rough environment with stones, wind and weather. Especially salt water is very hard on the equipment. We are also working on a very tight schedule on this project, and we simply cannot afford long downtime on machines. The Leica MSS420 sensor helps us keep the machines up and running for the planned operations,”Claus continues.

Marcus Grevelshoej, product specialist for excavator and wheel loader solutions, foresees that the new Leica MSS420 dredging sensors will prove to be very useful in many construction projects such asdeepening of harbours, digging of cables underwater, harbour installation, coastal protection, denaturisation and digging in raw material lakes.

“The MSS420 sensor can be programmed to boom 1, boom 2, stick, bucket and even tilt sensor. This makes the changing of sensors very easy, even for less experienced operators on the construction site,”says Marcus.

All excavators equipped with iCON excavate and GNSS can easily be updated to use the new submersible sensors.
