Electric driven vibration hammer for construction of Qingshan Yangtze River Bridge in Wuhan

The Qingshan Yangtze River Bridge in Wuhan is the eleventh Yangtze River bridge in Wuhan, with a cable-stayed bridge span ranking sixth in the world. It is an important passage through the Yangtze River for the Wuhan Fourth Ring Road. The bridge is located on the south bank about 1 kilometer downstream of the Wugang Foreign Trade Port, and on the north bank between Hualou Street and Shakou Village, close to Huangpi District. The bridge is constructed according to the standard of a two-way 8-lane expressway, with a design speed of 100 kilometers per hour. The entire line is covered by bridges, with a bridge deck width of 41 to 46 meters. The estimated total investment is 5.148 billion yuan. The construction of the bridge has already started.

Recently, steel casing insertion work was carried out for the Qingshan Yangtze River Bridge in Wuhan. This time, the diameter of the steel casing is 3 meters, the length is 42 meters, and the weight is 60 tons, making it a good diameter long steel casing for drilling on the Yangtze River. It has significant historical significance. Of course, our company's second-generation resonance free adjustable eccentric torque vibration hammer EP800 is used for insertion and punching work.

On the day of construction, the weather in the Yangtze River remained as humid as ever. Before construction, the construction team first conducts debugging work on the EP800 vibrating hammer. During debugging work, the EP800 vibration hammer performed very steadily. The debugging and vibration testing are very good. The quality of the vibrating hammer is so reassuring.

After the usual inspection, the lifting work began quickly.

The work of inserting and driving the steel casing began. Although the surrounding environment was muddy and humid, the EP vibration hammer quickly finished driving the steel casing. The insertion process is simple and accurate, and the steel casing that is inserted is standard and neat. The vibrating hammer product in vibration is impressive.

In this project, a steel casing was directly inserted and driven without a guide frame, and an adjustable torque vibration hammer was used to vibrate and sink vertically to within 0.4%, meeting the standards of a type of bored pile.

The EP800 vibration hammer from Zhenzhong is our brand product of Zhenzhong pile drivers. It has always been a close partner of pile foundation construction enterprises and has received unanimous praise and love from customers. The construction of the steel casing for the Yangtze River Bridge was completed through the cooperation between the EP800 vibration hammer and China Railway Major Bridge Bureau.

We believe that this steel casing insertion not only has important significance for the construction of the Yangtze River Bridge, but also makes our pile hammer products more deeply rooted in the brand influence of Zhenzhong.
