Description

Protect broken stake bobbing machine of muscle

Technical Field

The utility model relates to an electric power industry transformer substation pile foundation construction technical field, concretely relates to protect broken stake bobbing machine of muscle.

Background

The pile foundation construction of the transformer substation is very important, the pile breaking work of the pile foundation is particularly important, and whether the quality of the pile foundation and the quality of the steel bars meet the requirements or not is controlled in the pile breaking process.

Pile breaking (also called pile head breaking): when pouring the cast-in-place pile, the top elevation of the cast-in-place pile should be 0.5 to 1.0m higher than the designed top elevation of the pile so as to ensure the strength of the pile head concrete, but the part of the pile head higher than the designed top elevation of the pile must be chiseled off in the subsequent process construction, and the chiseling off of the part of the pile head concrete is called as 'broken pile head'. In order to guarantee pile head quality in the time of pile foundation construction, pile bolck elevation all will generally be higher than the design elevation, for example bored concrete pile: when the concrete is poured, sediment at the bottom of the pile and impurities precipitated in slurry in the pouring process can form a certain thickness on the surface of the concrete, generally called as floating slurry, so that after the concrete is solidified, the excess pouring part is chiseled off, main ribs (steel bars) above the elevation of the pile top are exposed, and after the pile foundation is detected to be qualified, the construction of the bearing platform is carried out.

The existing pile head breaking tool mainly comprises manpower and machinery, the mechanical name of the pile head breaking tool is a pile breaking machine, a pile cutting machine and the like, the speed is many times faster than that of the manpower, and if the construction period is shorter, the pile head breaking tool is generally broken by the machinery. However, the technical defects existing at present are as follows: the manual breaking efficiency is low, and the operation risk is high; the mechanical breaking is easy to damage the pile body in the construction process, and particularly causes loss to the steel bars of the pile foundation.

Due to the fact that pile breaking workload is large, potential safety hazards are large, required repetitive workload is large, and the existing breaking mode is difficult to meet the requirements.
