Description

Technical Field

[0001] The utility model relates to the field of pile foundation construction, in particular to a device for statically cutting a pile head. Background Art

[0002] In the field of construction, prefabricated pipe pile foundations are increasingly widely used because of their advantages of fast pile formation, shortened construction period, simple construction management, civilized on-site construction, and little impact on the surrounding environment. In the construction of pile foundations, the actual elevation of the pile tops of most piles will be higher than their designed elevations. Therefore, the part higher than the designed elevation needs to be cut off. Currently, the excess concrete of prefabricated pipe piles is mostly cut off by manual sledgehammers or hand-held cutting machines. Although this reduces labor costs, there is a risk of damaging the internal steel structure. The consequences of this risk may be large or small. In severe cases, it may lead to unstable building structures and affect the safety of people's lives and property. In order to avoid this situation, a device for statically cutting pile heads is needed, which is easy to use and does not damage the internal steel structure, so that the overall building is firm and safe and reduces unnecessary hidden dangers.
