精确地磨substrate as a basis for safe, durable streets

Author: Ilona Bihlmayer

土木工程和道路建设部门面临着越来越多的挑战。在高速公路建设方面，公共当局需要较短的构建时间，以使交通堵塞和交通拥堵最少。其他挑战包括，由于国际商品的流动，通勤交通的增加，道路上的单个汽车数量的总体增加以及这些汽车的大小和重量，重型良好的车辆数量增加。

由于所有这些原因，土木工程和道路建设部门的公司需要特别勤奋，以确保道路更安全，更坚固，并且持续时间更长。从理论上讲，委托构建者提供的道路的计划参数和目标值应确保地表水的最佳径流，良好的负载分配和耐用性。

多亏了数字测量解决方案，这种道路更加艰难，更安全

Using digital measurement solutions in road construction helps to transfer these target values into precise actual values on the ground. For this reason, Mr Stahl, head of the surveying department at LEONHARD WEISS decided to use a digital solution from Leica Geosystems for the milling work on the renovation of the superstructure of the German A70 autobahn (BAB A70), to speed up the work and ensure it is precise.

对于这个项目，巴伐利亚州通过北巴伐利亚高速公路部门在设计指南中为建筑公司提供了计划数据和目标价值。在翻新道路时，铣削现有的表面层是重要的一步。精确铣削的底物是在设计指南中详细介绍的，具有精确的交叉坡度和梯度的详细说明。

数字化应提高效率和精度而不会阻碍进步

“The aim of this project is to use 3D profile milling to create a base with exactly the right profile, which we can then build on,” explains Mr Stahl. He needs a system that is “ready to use quickly, so that the construction process is not brought to a standstill.”

When selecting a measurement system for the team and Stefan Stahl, easy-of-use and minimal effort required in upgrading the milling machine were also important factors.

Leica GeoSystems的入门级，GNSS支持的铣削解决方案满足了所有这些要求，因此Stahl选择了Leica Icon Site磨坊飞行员。

As LEONHARD WEISS was already using the Leica iCON iCG70 and iCG60 construction rovers, the CC80 construction controller, and the iCON site-field software, introducing the Milling Pilot System was seamless. The iCON site software, developed specifically for positioning tasks in the construction industry and which runs on all Leica iCON-GNSS hardware, was particularly helpful here.

“Our team found it easy to operate the Milling Pilot. The software is intuitive, the milling process was displayed graphically and it helped us to set the milling depth accurately,” stressed Stahl. A brief on-site introduction to the system was all that was needed for the entire milling team to be able to use the system.

土木工程和道路建设的全方位数字解决方案

这样的项目越来越多地通过数字方式处理。在这种情况下，现有站点是由工程公司数字化调查的，然后将数据传输到图标软件中。

The target values from the design guide were then loaded into the software, and the delta, the section that needed to be milled away, was calculated. The 2-step preview of the target and cross slope values on the main set points along the road enabled consistent milling with no unevenness.

The software’s visualisation function meant that the error-prone spray-on marking process was not necessary and it saved time and costs compared to the manual preparation process. In road construction, costs are also incurred when additional layers need to be applied if the milling has gone too deep. This is also avoided by the increased precision the system provides.

Simple installation

The iCON site Milling Pilot simply requires an iCON-GNSS smart antenna, a CC80 controller and the relevant software. Positioned on the top of the milling machine, the antenna, in this case the iCON gps 70 T, sends GNSS correction data to the controller. This data is displayed graphically by the software.

Leica Geosystems的令人印象深刻的服务和支持

最初，莱昂哈德·魏斯（Leonhard Weiss）团队租用了该系统，以查看它是否适合他们。此后不久，他们投资了自己的系统。Stahl说：“在测试阶段并安装我们自己的系统时，我们从德国Leica Geosystems团队获得的服务和支持非常有帮助。”

Stahl继续说：“ Leica Geosystems团队为我们建立了一个单独的安装，该系统直接从机器上用电力供电，因此无需为电池充电。”

As a long-standing customer of Leica Geosystems, Stahl knows he can rely on Leica Geosystems for support with a wide range of projects and, in conclusion, said that “he would recommend the iCON site Milling Pilot without hesitation for its precision and ease-of-use. This, and all the other systems from Leica Geosystems that I have used, makes work on the building site easier every day. The Leica service team is always there to answer our questions and help us optimise our processes.”

Within a short space of time the entire milling team at LEONHARD WEISS GmbH & Co. KG was familiar with operating the iCON site Milling Pilot.

ICG70T令人印象深刻，不仅是具有精确GNSS数据的建筑工地漫游器，而且在铣床的顶部。
