Autumn is the golden period for intensive water conservancy construction.

Recently, the Dongting Lake water conservancy project in Hunan Province has been working day and night, sprinting towards the annual target. 15 XCMG XG500E diaphragm wall grab buckets stand tall, ensuring high-quality construction of underground diaphragm walls with an average construction efficiency of one wall per day!

As a national major water conservancy project and one of the top ten infrastructure construction projects in Hunan Province, the Dongting Lake key embankment reinforcement project includes 4.87 kilometers of cement-soil cutoff wall and 10.44 kilometers of plastic concrete cutoff wall, with a total investment of 281 million yuan. The entire construction task is planned to be completed by the end of March 2024.

The geological conditions at the site are complex, with the upper layer mainly consisting of soil. The diaphragm wall grab buckets need to penetrate hard rock layers for construction. The cutoff wall construction requires a depth of 20-43m and an effective thickness of 400mm. Both the time schedule and construction geology are quite challenging.

According to the site conditions, the XCMG XG500E diaphragm wall grab bucket is equipped with a specific 300mm thick bucket body, achieving an average of one wall per day, which is one-third more efficient than similar equipment, providing solid technical support for building a high-quality development lifeline for Hunan's water conservancy!

The XCMG XG500E diaphragm wall grab bucket features a dual-winch single-row rope structure, solving the problem of wire rope wear and increasing service life by 1-3 times; high and low speed lowering, with a maximum speed of 75m/min, tightens the wire rope during the grab closing process, reducing operational risks and improving trenching efficiency; and is equipped with a 1400KN thrust cylinder, enhancing the ability to break hard formations and providing wide adaptability to various strata.

After verifying construction efficiency and wall quality, the client praised: "XCMG diaphragm wall grab buckets have performed excellently in the Dongting Lake project, with fast trenching speed, energy savings, and guaranteed service. We will still choose XCMG equipment for future projects."
