Background of the project

The construction of the Hangzhou Qianqian High-speed and Medium- and Medium-Sized Repair Project started in early 2017. The maintenance of Hangzhou Qiandaohu branch line from south to Hangzhou was undertaken by Hangzhou Jiaojian Engineering Co., Ltd. The total length of the project was more than 100 kilometers. As a key project for the construction of “one and a half hours of traffic circle, tourism circle, and economic circle” in Hangzhou, Hangzhou-Qiandao Expressway is the golden channel between Hangzhou and Qiandao Lake, and also an important tourist channel connecting “Sanjiang, two lakes and one mountain”.

Equipment selection

As we all know, the highway maintenance maintenance has strict requirements for construction operations, construction equipment has a direct relationship between project quality and operating efficiency, but also directly affect the traffic safety and driving comfort after traffic development.

Hangzhou Jiaojian Engineering Co., Ltd. has stringent requirements for the selection of construction equipment. In this Hangqian high-speed 2017 major repair project, three sets of BW203AD dual-drum vibratory rollers and three sets of BF800C paver were adopted. With the help of reasonable construction equipment, efficient operation mode and stable operation performance, Hangzhou Qianqian Expressway is renewed under the joint establishment of the BMW Equipment, and it is intertwined with the surrounding mountain scenery.

Construction Site

The BW203AD dual-drum vibratory roller and the BF800C pavers on the Hangzhou-Qianhua Expressway have not only improved the engineering efficiency, but also achieved the unanimous approval of the owners due to their excellent work performance and outstanding performance.

Classic industry, BW203AD roller makes operation easier

The BMW BW203AD double drum vibratory roller is a classic BMW Gear compactor. This model adopts dual-frequency and double-amplitude design, which can make the vibratory pressure force more evenly distributed in the steel wheel girder section; walking motor and vibration motor directly with steel The wheel connection increases the quality of the vibration and makes the vibration pressure stronger.

Roller in construction

The operator is also not surprised to praise the BMW Vibratory BW203AD dual drum vibratory roller. The more humanized design makes the operation more convenient. The large visual range can clearly observe the working status of the surface of the drum roller and the sprinkler system, and the entire construction. process.

Advanced design, BF800C paver makes construction more efficient

BF800C paver, as the representative of BMW's classic pavement equipment, has inherited Germany's advanced design concepts and rigorous production processes. The paver has a uniform material discharge, high flatness, less segregation, easy paving operation, and operation. The temperature can be accurately changed in the display; the special designed driver's seat makes the operator more comfortable while avoiding excessive harm to the body caused by asphalt smoke, safer use of the equipment, lower energy consumption, and high construction efficiency.

In the construction site of Hangzhou-Qianlong Expressway for many months, the zero failure rate of the BW203AD dual-drum vibratory roller and the BF800C paver has perfectly demonstrated the excellent product quality of the BMW Machine. The efficient operation ability and perfect construction results, together with the timely communication and caring service of after-sales service personnel, have become the unique characteristics of BMW.
