In the near future，The autumn wind is cool，The sky is clear，It is a good day for construction.，At the site of the first phase of Changsha Metro Line 7，Sunward intelligent two-wheel slotting machine is busy working.，This is also the first time that the device“Take command and go to war”。November fifth，Xia Zhihong, General Manager of Sunward、Zhu Zhenxin, General Manager of Basic Equipment Business Department, and his delegation visited the project site.，Understand the construction progress of equipment。

The total length of the first phase of Changsha Metro Line 7 is 16..84 kilometers，The project started on December 24, 2021.，There are 16 stations，Including 9 transfer stations。With the completion of the first floor of the main structure of Changsha Metro Line 7 in mid-October,，Line 7 has officially entered the construction stage of the main structure of the station.，At present, the construction of each node is speeding up.。

The first phase of Changsha Metro Line 7 is an encrypted supplementary line in the main urban area of Changsha.，The engineering geological conditions and environment along the line are relatively complex.。At the Yaoling station，The customers of Shanhe Intelligent Rotary Excavation who participated in the construction encountered technical difficulties in the construction of underground continuous wall.，Resulting in a slowdown in construction.。After learning that the customer is having a problem，Sunward Intelligence called for R & D at the first time、Technology、After-sales、Operators and other personnel，Set up“Yaoling Project Team”，Actively provide solutions for customers——That is to say, the double-wheel slot-milling machine is used to solve the construction problem of underground continuous wall.。

  

Actually，In early 2022，The double-wheel slot milling machine independently developed by Sunward Intelligence has been officially unveiled.，The maximum grooving depth of this equipment is 120 meters.，Grooving precision 1/1000，All technical indicators are in the leading position in the industry.。Out of the pursuit of excellence in quality，After the equipment is offline，Sunward isn't rushing the device to market.，Instead, a period of rigorous in-plant testing was conducted.。

A series of tests and improvements，The performance of the equipment is more perfect.，It also casts the extraordinary quality of Sunward intelligent double-wheel slot milling machine.。SWHCAfter the 120 double-wheel slotting machine enters the construction site,，Even though the construction of the first channel is facing a 50 cm thick layer of untreated reinforced concrete layer of the original Red Flag Canal.，It can also be easily won.。In the subsequent slot segment，Milling speed of 6 meters per hour，Change the original slotting time from 3.5-4 days reduced to 2-3 days。

  

In the process of communication，The customer sent an expert team to Sunward Intelligence to provide technical guidance for the construction project.，Thank you for providing professional solutions and excellent after-sales service.。At the same time，Xia Zhihong also encouraged the intelligent technicians and service personnel stationed in the construction project.，Do a good job of safety protection and epidemic prevention in operation，Make every effort in the construction of key projects，Help the project to be completed efficiently and with high quality。
