Reduce the impact of public travel，Construction is a race against time
In order to improve the living environment of the county and the water quality of Fenhe River.，Implementing the Provincial Party Committee and the Provincial Government“Clear water flows into the Yellow River”A major strategic deployment.，Lingshi County has implemented the comprehensive transformation project of rain and sewage diversion.。
This project is the second phase of rain and sewage diversion reconstruction project in Lingshi County.，The whole project is constructed by Lingshi County Urban Management Bureau.，Shanxi Xingze Road and Bridge Engineering Co., Ltd. undertook the pavement works from Beiwangzhong Bridge to Shuitou Bridge。
The road section where the project is located is one of the main roads in Lingshi County.，It is the gateway road of Lingshi County.，It bears a huge traffic flow every day.。During the reconstruction of this road，The other main road will be under tremendous traffic pressure.。In order to minimize the impact on public travel,，The construction period of the project is crucial.。
The road section to be resurfaced this time is 4 km，The paved area is 65000. ㎡。This means that the construction unit is facing a tough battle.，Construction quality shall be guaranteed，We have to race against time to complete the project.。This is the construction organization ability of the construction unit.、Performance of construction equipment、Considerable demands are placed on efficiency and reliability。
Collaborative work，More efficient
In order to ensure the diversion of rain and sewage and the road upgrading and reconstruction project in Lingshi County，High standards、High quality、Completed efficiently，The construction party, Shanxi Xingze Road and Bridge Engineering Co., Ltd., is equipped in the field of road construction and maintenance.，Wirtgen Group, which has a good reputation for its performance and construction quality, is the main construction fleet of pavement equipment.。
A total of 14 sets of Wirtgen Group pavement equipment have been invested in the whole project.，These include the Wirtgen Milling Machine.、Fogler Paver、Humvee roller。Multi-type professional equipment performs its own duties，Synergy，Adopt the concept of rapid maintenance of urban roads，Race against time，Win with professionalism and detail，The construction task was successfully completed.。
At the project construction site，The efficient coordination and fine construction between the equipment of Wirtgen Group is a highlight.。
Early stage of the project，Two Wittgen large Milling Machines were used by the construction party in advance.，Milling removal of old road surface。Wirtgen 2m gear large Milling Machine，Equipped WIDRIVE Intelligent milling system，Through LEVEL PRO PLUS Millimeter-level automatic leveling system，Achieve high flatness of the milling surfaces，Lay a good foundation for the flatness of subsequent paving operation。At the same time, two small milling machines are also used.，It's like a micro-plastic scalpel.，To the edge of the road、Flexible removal of corner areas around the manhole cover，Labor saving and higher efficiency。
At the 2-day paving construction site，A Wittgen half-meter milling machine is responsible for cutting the road.；Vogler's rubber-tyred Paver is responsible for paving complex working conditions such as forks.，Pave more efficiently while ensuring flexibility；
The Hummer small roller cooperates with the large roller on the road edge and the transition surface.、Areas such as the edge of the manhole cover shall be compacted.，Ensure that there are no dead corners in the compacted area，The flatness and compactness of the whole surface layer are better。
Among them, the key part of the whole construction schedule is the large area of asphalt pavement.，By Vogler Medium Paver Super 1680 Li Super 1900, a large paver commonly used for high-grade roads-3 L；Super 2100 -3 L Three-machine laying in parallel，Share the burden。
The brilliant performance of Wittgen Group's multi-equipment collaborative operation has also won the unanimous recognition of the construction unit personnel.：“The synergy between Wirtgen Group's brand equipment is very good.，Be in step，Very efficient construction，65000 m² The construction area was completed on schedule in only two days.。“
Strength escort，Quality Engineering
It is worth mentioning that，Vogler's new medium paver Super 1680 working in the field Li ，The appearance size is compact，Strong mobility，Maximum paving width up to 7.8 m。Up to 15 t The large hopper is easily matched with various types of skip cars on the construction site.，Standard lifting auger lifting function。Adjustment range of auger up to 15 cm, The position and height of the cloth packing auger can be adjusted synchronously according to the change of the paving thickness.，Always ensure a stable, full-width spread feed，Reduce material segregation，Ensure ideal paving quality。This medium-sized paver can not only be easily competent for urban road maintenance and reconstruction construction，It can also cooperate with large pavers to expand operations.。
At the project site，Paving by three pavers，Adopt“Heat on heat”Paving process，A continuous line is paved over the entire paving width、Seamless finish。Super 1680 Li The paved surface layer maintains the same high quality level as the other two large pavers commonly used in expressways in terms of flatness and pre-compaction.。
The subsequent compaction work was carried out by four large Hummer double steel wheels.。It is worth mentioning that，The project includes a new generation of Hummer heavy duty high frequency double steel wheels. HD 138i VV ，And oneHD 128 VO Oscillating roller。Vibrate through the Humvee+Compaction mode of oscillation combination，So that that compaction efficiency is high。
Hummer's new generation of heavy-duty high-frequency double-steel wheels HD 138i VV Carry HAMMTRONIC Intelligent compaction control system，With compaction constant speed cruise，Vibration frequency and amplitude remain constant，Flexible start-stop and other intelligent functions，Avoid misoperation，The compaction effect is more uniform and stable.。
This roller has 60 Hz Optimized high frequency vibration system，Can realize the high-speed compaction of the middle and upper surface layers while ensuring the compaction quality，It can better adapt to the short construction window period of municipal construction.。
It is worth noting that，The construction site is equipped with the new generation equipment of the fourth national standard of Wirtgen Group.，At the same time, there are also old models that have been tested by the Chinese market for a long time.。Whether it's a new model or an old model，In the course of use, it has maintained a high level of construction quality and stable and reliable construction performance.。
In addition，From pre-construction process and step planning to on-site support and guidance during the project，The service teams of Wirtgen China and local agents have maintained close contact with the construction team.。The professional skills and rich application experience of Wittgen China Service Team are also the strength of the construction side to deal with such construction challenges.。
Paving to complete the new flat surface course
After the completion of the second phase of the rain and sewage diversion project in Lingshi County, the short board of infrastructure in the county will be further completed.，Promoting the Improvement of County Water Environment Quality，For“Clear water flows into the Yellow River”Lay a solid foundation。
