Background
During pile foundation construction, due to various reasons such as uneven distribution of geological soil layers and the like, the elevation of a plurality of pile tops is higher than the designed elevation, and after a foundation pit is excavated, the pile bodies higher than the designed elevation are cut off, namely, the pile cutting is called.
Generally, when the height of a pile to be cut is low, the pile cutting is relatively safe, but a pile body to be cut is high in height and high in mass, and when the pile is cut, a constructor is extremely easy to collapse and injure at the moment of cutting without taking a pile stabilizing measure. The actual situation of the solution is here as follows: the excavation of the foundation pit can be carried out according to each layer not more than 1 meter in a layering mode for multiple times, the excavation is suspended after each layer is excavated, meanwhile, the pile is cut once, namely, the pile is cut for multiple times in a segmentation mode not more than 1 meter, and when the cut pile is low in height, the cut pile is relatively safe. However, the scheme seriously influences the construction period progress and the economic cost, and is hardly adopted in the actual construction practice; the large excavator is parked near the pile body to be cut, and the pile body to be cut is suspended by a steel cable. Also because of economic cost, the method is hardly adopted in practical construction practice; the tower crane is actually idle at the moment, but the tower crane is not enough to bear the load of suspension pile breaking or pile breaking dumping; in addition, the method of building and supporting the foundation soil around the pile section to be cut is not feasible, because no hardened foundation exists at the moment, only a soft and wet soil layer is formed, and the toppling load of the broken pile cannot be supported; therefore, in actual construction practice, accidents are basically prevented by means of the fact that the tip and the legs of pile cutting operators are fast dodged and avoided, and the accidents are obviously unreliable and leave great potential safety hazards. Thus, such accidents sometimes occur.
