Recently, the first diaphragm wall trench of Phase II of Jinan Metro Line 3 was excavated. The XCMG XG500E hydraulic diaphragm wall grab, as the main construction equipment, made a major entrance to ensure trenching accuracy and construction efficiency.

As the first step of foundation pit excavation, the diaphragm wall plays a supporting and retaining role for important functions such as underground water cutoff, seepage prevention, load bearing and water blocking!

Considering that the geological conditions and construction environment along Jinan Rail Transit Line 3 are extremely complex, the project contractor selected the XCMG XG500E hydraulic diaphragm wall grab, which offers first-class performance and rich construction experience, as the builder of the "impregnable wall".

Jinan Metro Line 3 passes through terrain that is high in the south and low in the north, with an elevation difference of about 168 m, and the geology varies greatly. The southern section is dominated by hard rock, with many sensitive buildings nearby; the northern half consists of soft soil layers rich in water and under high water pressure, placing extremely high demands on waterproofing.

The XCMG XG500E is equipped with a large-size heavy-duty crawler chassis, which gave full play to its advantages in the project's terrain with large elevation differences. Its long guide and low-resistance grab body structure provide high trenching accuracy and strong grabbing capability, and in extremely complex terrain it fully utilizes the 90° or 180° grab body rotation function, perfectly meeting the construction requirements of special-shaped trenches in narrow working areas.

XCMG's hydraulic diaphragm wall grab series adopts a dual-winch single-row rope structure, with high/low two-speed winch lowering speeds, greatly improving construction efficiency, achieving economical fuel consumption and effectively reducing construction costs!

Seeing the overall performance of the XCMG hydraulic diaphragm wall grab on site, the customer praised it: "This XCMG grab not only grabs accurately and quickly, but also economically. The construction method support from XCMG's technical staff is even more reassuring and worry-free."

With the full-scale commencement of projects such as Jinan Metro and Qingdao Metro, the XCMG XG500E and XG700E hydraulic diaphragm wall grabs have become highly sought after in the market, helping the development and utilization of underground space in Shandong with their stable performance and fast trenching speed.

After years of deep cultivation, XCMG hydraulic diaphragm wall grabs have left their footprints in cities and villages of all sizes across China as well as important international markets, charging into battle on construction sites all the way. Through tempering and continuous innovation and improvement, they have also created today's full series of XCMG hydraulic diaphragm wall grabs that adapt to multiple working conditions and achieve high trenching accuracy, contributing XCMG strength to the development and utilization of underground space!
