In the field of foundation construction, technological advancements have taken place, and hydraulic pile-cutting equipment has helped enhance the efficiency of the projects.

　　In the field of pile foundation construction, breaking the pile head - that is, cutting off the part of the pile that exceeds the designed height - is a crucial preparatory process that links the pile foundation with the upper structure construction. This process not only affects the transfer of structural load capacity, but also influences the entire construction period and on-site operation safety. Among the methods for breaking the pile head, the mechanical cutting method uses professional cutting equipment and is suitable for reinforced concrete piles, with high efficiency but requiring a large investment in equipment; the manual crushing method uses tools such as pneumatic hammers for manual crushing, with lower costs but higher labor intensity; the hydraulic shearing method uses hydraulic shears to quickly cut the pile body, suitable for high-strength concrete piles, with significant efficiency improvement but requiring professional equipment.

　　During the evolution of the pile head breaking construction method, the development of hydraulic pile cutting devices has become a new focus of industry attention. The open-closed hydraulic pile cutting process proposed by the researchers achieves the mechanized removal of the pile head through hydraulic devices, which can effectively address practical problems such as restricted net height and enlarged pile heads in engineering projects. Some construction enterprises are also actively laying out in this direction. Among the multiple hydraulic pile cutting-related invention patents obtained by Shanghai Construction Group, there are construction methods for hydraulic pile cutting and open-closed hydraulic pile cutting devices. This device and construction method can achieve segmented cutting of the pile head and automatically adjust the mechanical posture according to the requirements of the cutting height. Compared with traditional pile head processing methods, it can reduce manpower input and lower the operational risks at the construction site. From manual construction to mechanical assistance construction and then to mechanical pile cutting, this reflects the technological leap of engineering equipment in the field of foundation construction.

　　In the context of a stable construction scale for pile foundations, the demand for mechanized equipment for processes such as breaking the pile heads will continue to expand. The hydraulic shears that are compatible with excavators can serve as the equipment carrier for pile cutting operations. By changing the attachments, multiple operations such as excavation, pile cutting, and material transportation can be accomplished on the same excavator. This "one machine, multiple uses" configuration model has certain value for construction enterprises in reducing the comprehensive holding cost of equipment. The hydraulic shears produced by Yantai Zhongxindai Hydraulic Equipment Co., Ltd. can be adapted to excavators of different tonnages and can be applied to the cutting operations of concrete pile bodies in foundation construction. In terms of production capacity and equipment matching, the company relies on the industrial conditions in Yantai for continuous optimization. As the requirements for construction quality, safety management, and schedule guarantee in the foundation construction field continue to increase, the mechanization and hydraulicization of pile cutting processes will become an important development direction, which will also open up a broader application space for hydraulic shears and other accessory products.
