Recently，News released by Guangdong Communications Group，Guangdong-Hong Kong-Macao Greater Bay Area“Deep and medium passage”Construction of asphalt pavement in the submarine immersed tube tunnel of the project begins，It marks that the pavement construction of the whole line of the project has entered the sprint stage.。

Deep and medium passageIt's a set“Bridge、Island、Tunnel、Underwater communication”An integrated cross-sea cluster project，It's the country“The 13th Five-Year Plan”Major projectsAnd《Pearl River Delta Planning Outline》Determine the constructionMajor transport infrastructure projects，It connects the three major areas of Guangdong Free Trade Zone.、Communicate with the Pearl River Delta“Shenzhen, Dongguan and Huizhou”And“Pearl River”Two major functional groupsImportant transportation link，It is also a convenient passage from eastern Guangdong to western Guangdong and even southwest China.。The total length is about 24 kilometers.，Among，Total length of tunnel pavement works is 6.8 kilometers，The total construction area is 260,000 square meters.。

“Subsea Tunnel Asphalt PavementIt is the last key process of the project pavement engineering.，The space inside the cave is relatively closed and has a length of 6 kilometers.，Its high temperature and high humidity、Poor ventilation、External conditions such as super-wide and super-long bring great challenges to the construction of asphalt pavement.，The smooth implementation of the first article section，It has laid a good foundation for the next stage of continuous construction.。”Huang Lei, Deputy Head of Pavement Engineering Management Group of Shenzhen-Medium Passage Management Center, introduced。

XCMG equipment construction in full swing

On the construction site of asphalt pavement，Several XCMG high-end double-drum road rollers are carrying out asphalt compaction operations.。XCMG high-end oil surface equipmentFully considered at the beginning of the designSpecial environmentConstruction requirements in，In extreme environments, it mayEfficient、StableRun continuously，It provides a strong guarantee for the smooth implementation of the subsea tunnel asphalt pavement project.。

In this project，XCMG double steel wheel is relying onStrong compaction capacity、Excellent construction qualityAnd efficient、Stable construction performance，It is favored by the owners.，Participate inHigh standards、A highly demanding national levelFrom the project。It's not just right.XCMG high-end oil surface equipmentFull recognition of technology and quality，It is also a high affirmation of XCMG's brand strength.。

At present，Shenzhen-Medium Passage Positive Propulsion Electromechanical、Traffic safety、Construction of ancillary works, etc.，It is planned to be open to traffic in June.。
