In January 2012, Jiangsu TYSIM Machinery Technology Co., Ltd. produced KP315 full hydraulic pile cutting machine, which is a brand-new concept of pile breaking equipment. It adopts modular design, uses pressure oil as power, and a single drill rod can provide 280KN of pressure. It is mainly aimed at all round cast-in-situ piles and pipe piles with diameters ranging from 300mm to 1800mm. The construction can be carried out according to different pile diameters and flexibly adjust the number of modules, and the national invention has been obtained.

In April 2012, China's first self-developed fully hydraulic square pile cutting machine (square pile machine) KP500S was rolled off the production line of Jiangsu TYSIM Machinery. In June, it was shown to a construction site in Suqian, Jiangsu Province. The construction site is located in Suqian City, Xuzhou. It is the second phase of a commercial housing project. The designed buildings are all based on reinforced concrete precast square piles with a pile diameter of 400mm × 400mm. After the pile is sunk, the height of the broken pile is about 1.2 meters. About 120 piles need to be cut off for each building. Party A requires each building to complete pile breaking within 3 days after piling. Due to the tight construction period, the building uses artificial pneumatic picks to break piles, which is very inefficient. Starting from the second building KP500S square pile machine construction.

Boss Hu, who bought this KP500S, used to use artificial pickaxes to break piles for a long time, but now he has special equipment. Although the team has dropped sharply from more than a dozen people in the past to five now, he is confident in the current project and constantly puts forward some opinions and ideas in combination with the actual situation.

At the beginning, the 25T crane was used as the carrier, and the KPS15 hydraulic pump station developed by TYSIM Machinery was used to provide the power source for it. After a short exploration, the tower crane on the construction site was directly used as the carrier to cooperate with the KPS15 hydraulic pump station, thus the economic benefits were obviously improved. And the preliminary line has become a set of perfect square pile machine construction mode.

KP series pile cutting machine is powered by engineering machinery carrier or hydraulic pump, and the concrete is crushed by the special shape of the drill rod head. It does not cause any damage to the pile body buried in the ground.

At the construction site of a residential building in Zaozhuang, Shandong, in the foundation pit, the height of the pile to be broken is more than 3 meters, the pile diameter is 900mm, and there is a large amount of water, so it is quite troublesome for personnel to approach and deal with it. The KP315 pile cutting machine was ordered in the face of danger. With the assistance of the crane, the length of the lifting chain was properly adjusted, and this "impossible" task was easily completed.
