[0002] With the continuous development of science and technology, cities have also begun to develop housing and construction, which will increase the construction of buildings in cities. Basic infrastructure projects can better improve the beauty of the city and optimize the living environment of citizens. Usually, before the construction of some higher-rise buildings, deeper foundation columns will be constructed to ensure the overall stability of the subsequent buildings. The foundation columns of the buildings need to have a certain length of pile heads remaining. After the construction is completed, the exposed foundation column pile heads will be removed to avoid cracks in the head of the foundation columns.

[0003] Usually, the base column pile head needs to have a groove cut at its root first, and then squeeze or knock from the groove of the pile head to form a horizontal crack on the pile head, so that when the pile head is subsequently removed, no vertical crack will be formed, avoiding damage to the base column as a whole. When the groove of the pile head is cracked, electric hammers and other equipment are usually used, which requires manual operation. The efficiency of manual operation is too low, and the crack is difficult to control, resulting in the problem that the cracking process is too difficult. Utility Model Content
