Description

Topic: New technological solutions applied in construction of skyscrapers.

In recent years, concrete pile pressing method to reinforce foundation has been applied in the construction of many skyscrapers. However, the working process in encountering a number of obstacles due to difficulties in transportation, high cost and constraint in human force.

Currently, construction machine-building industry in Vietnam has not been capable of manufacturing high-efficient machinery. The high quality ones still need to be imported at very high cost.

Therefore, enterprises should focus their attention to new technologies in construction material industry in order to enhance efficiency, reduce cost and minimize labor cost.

Witness workers’ daily struggle in the construction field, Director of Thanh Loi Company Ltd. Has successfully researched and manufactured the first hydraulic pile pressing machine in Vietnam after many efforts.

Robotic hydraulic pile pressing machine operates with a system of motions that is reducing motor capacity, increasing working capacity and easy to move from one site to another site. The machine weighs about 400 tons and can be designed to 1,000 tons depending on construction requirements. Its pressing power can go up to 400 tons of dynamic force. The machine can be controlled to automatically turn 180 degrees, move backward and forward with each distance step of 3.5m, move sideways with 1m step distance without lowering the land surface.

The machine costs about VND 5 billion to be manufactured that accounts for only 70% of imported machines. The average number of piles and pressing depth per day are about 10 times higher than the traditional method. In comparison to with imported machines, it has higher weights and larger compression pressure.

Intelligent hydraulic pile pressing machine is design for pressing round, square, and H-shape piles in all types of terrain and with all lengths of pile. The making of noise, level of environmental pollution and impact on surrounding atmosphere are minimized that is suitable for the urban construction with high limitation in concussion.

With this innovation, Nguyen Van Sau was awarded with the Certificate and Merit for the Champion in Bac Giang Technological Innovation Contest approved by Chairman of Bac Giang province.

This creation of hydraulic pile pressing machine is considered as an effective solution for businesses, construction companies in the building’s foundation construction.
