In August 2013, the cold regeneration overhaul of the East S329 Provincial Highway in Baofeng County, Pingdingshan City, Henan Province began. After review and approval by the project department, a Road cold recycler unit organized by Zhoukou Longyu Engineering Machinery Company entered the site for construction. Zhoukou Longyu Company is the earliest user of our company's Road cold recycler machine. The Road cold recycler machine coming in this time is a 600-horsepower WR2300L Road cold recycler machine that was shipped in 2011 and is equipped with a detachable heavy-duty rotor. The western section of Baofeng S329 Provincial Highway is a water-stable subgrade. The materials in the subgrade include pebbles and quartz sand, which have high strength and hardness. Such subgrades will cause the cold recycler to work slowly, wear fast, and even cause cold. The recycling machine cannot complete the milling operation. According to the staff of the project department, several Cold recycler have been here before, and all of them left the test and couldn't move after leaving the car. Zhoukou Longyu Machinery Co., Ltd. fearlessly organized the construction, and completed 12,000 square meters in the first four days of construction. Such a high-intensity Road cold recycler project reached such a construction speed, thanks to Zhoukou Longyu's skilled Road cold recycler construction technology and Our company has advanced Road cold recycler machines. Adjacent to the bidding section was an imported 2500 Road cold recycler machine, which entered the market at the same time. It only took 3,000 square meters in four days. The owner saw that the work was too difficult, the tool was too much, and he took the initiative to leave the field. On the seventh day of construction, the project department decided to take core inspections for the first day of the construction section. A total of seven core samples were taken. All core samples were successfully obtained. The core sample length reached 35 cm. This good construction quality made the project department and the quality The procuratorate was surprised.

Road cold recycler construction technology still belongs to a new type of roadbed construction technology in China, and there is no fixed construction technology specification. It is still the first application in many areas. The quality of construction often depends on the performance of the machine, the experience of the specific construction organizer and operators. Many inexperienced Road cold recycler units do not master reasonable Road cold recycler construction technology, which leads to the instability of Road cold recycler construction quality and even affects the promotion of Road cold recycler application technology. However, road Road cold recycler technology has many advantages, so road Road cold recycler The application of technology is still expanding year by year. Zhoukou Longyu Company did not do the test section in this project, and the core was also drilled on the working surface on the first day of construction. All seven core samples were successfully used to show that the Road cold recycler quality of this project is very stable. The success of this difficult Road cold recycler project further demonstrates that the proper Road cold recycler construction method is mastered, and domestic machines can fully do Road cold recycler projects. Even if some imported machines are not good enough, skilled users use me The Road cold recycler machine produced by the company can also make high-quality Road cold recycler projects. Zhoukou Longyu Company entered the field of Road cold recycler construction earlier. It has undertaken dozens of water-stable subgrades and lime soil subgrades. It has gradually mastered a set of reasonable Road cold recycler processes. The projects undertaken in the past two years have always ensured high-quality engineering. , And further promoted the company's Road cold recycler machine technical performance and product quality improvement.
