Intelligent hydraulic pile presses are highly effective

With the invention of a smart hydraulic pile press machine, Mr. Nguyen Van Sau, born in 1956, Director of Thanh Loi Limited Liability Company won the first prize of the Bac Giang Provincial Technical Innovation Contest in 2011.

Mr. Nguyen Van Sau introduced the model of hydraulic pile presses.

Intelligent hydraulic pile pressing machine (also called by Mr. Sau with another name " Robot pressed pile" ) has been researched, manufactured successfully and put into operation to bring high efficiency in the field of examination. public construction of high-rise buildings from April 2010.

Up to now, construction machinery manufacturing industry in Vietnam has not yet built a hydraulic pile press machine but still has to import and use foreign machines to press piles, build foundation and foundation works. High-rise and modern houses.

Many years ago, Mr. Sau and the workers of the company only specialized in making concrete piles, providing construction contractors in the provinces of Bac Giang, Bac Ninh and Lang Son.

Every time he undertook a project, he had to mobilize a lot of workers to work, but the efficiency was often not high and it was difficult to ensure progress. Therefore, Mr. Sau thought and thought to design and create a type of press machine with a large number of concrete piles, suitable for all strata and cheap, more convenient conditions, replacing the type of machine. imported. After many days of research and exploration, Mr. Sau successfully built the first intelligent hydraulic pile press machine in Vietnam.

Intelligent pile presses - Mr. Sau's "pile presser" is designed to include brackets, presses, crane lifting systems, hydraulic systems, electrical systems ., with pile-driving features , pressing piles, moving, changing direction. The machine weighs about 400 tons (can be added weight up to 1,000 tons, depending on the construction requirements of the contractors) and pressed 400 tons of dynamic force (equivalent to 180 tons of static force).

The controlled machine can automatically rotate 180 degrees, go forward and backward with a distance of 3.5 meters per step, traverse the distance of 1 meter per step without land subsidence. Machine with self-propelled crane, power supply, hydraulic pump .

The cost for manufacturing machines is about 5 billion dong (only 70% of the price of imported machines). The average number of piles and piles depth is about 10 times higher in a day than the manual pressing method; Compared to imported machines, this machine also has a higher weight and compression pressure.

Hydraulic pile press machine designed by Mr. Sau is suitable for construction of pressing round piles, square piles, H-pillars in all types of terrain and the length of piles is not restricted. When construction, pile presses cause less noise, no pollution and vibration in the surrounding environment, so it is suitable for construction of works in urban areas and areas with vibration limits. as close to old, weak buildings and weak strata.
