In January 2012, Jiangsu Taixin Machinery Technology Co., Ltd. produced the KP315 full hydraulic pile cutter. This is a new concept of pile breaking equipment. It adopts a modular design and is powered by pressure oil. A single drill rod can provide The pressure is 280KN. Mainly for all round cast-in-place piles and pipe piles with a diameter in the range of 300mm-1800mm, the number of modules can be flexibly adjusted for construction according to different pile diameters, and it has been a national invention.
In April 2012, my country’s first self-developed fully hydraulic square pile cutter (square pile driver) KP500S was launched at Jiangsu Taixin Machinery, and was unveiled at a construction site in Suqian, Jiangsu in June. The construction site is located in Suqian, Xuzhou. It is a commercial housing. In the second phase of the project, all the designed buildings use reinforced concrete prefabricated square piles as pile foundations, pile diameter: 400mm×400mm. After the pile sinking elevation, the height of the broken pile shall be about 1.2 meters. Each building needs to cut about 120 piles. Party A requires that each building be destroyed within 3 days after the pile sinking. Due to the very tight construction period, artificial pneumatic picks are used to break piles in the building, which is very inefficient. The KP500S square pile driver approached construction from the second building.
Boss Hu, who bought this KP500S, used artificial pneumatic picks to break piles for a long time. Now he has special equipment. Although the team has dropped from more than ten people to five people now, he is confident and constantly facing the project in front of him. Put forward some opinions and ideas based on the actual situation.
At the beginning, 25T crane was used as the vehicle, and the KPS15 hydraulic pump station developed by Taixin Machinery was used to provide the power source for it. After a short period of exploration, the tower crane on the construction site was directly used as the vehicle to cooperate with the KPS15 hydraulic pump station, which greatly improved the economic benefits . And initially formed a complete set of square pile machine construction mode.
The KP series pile cutter is powered by engineering machinery carriers or hydraulic pumps, and the pile body is squeezed through the special shape of the drill rod head to crush the concrete. No damage to piles buried in the ground.
In the construction site of a residential building in Zaozhuang, Shandong, in the foundation pit, the height of the broken piles is more than 3 meters, the pile diameter is 900mm, and there is a lot of water. It is very troublesome for people to approach and deal with it. The KP315 pile cutter was ordered in danger. With the assistance of the crane, the chain length was adjusted appropriately, and this "impossible" task was easily completed.
