Detailed Description

The invention will be described in further detail with reference to the following detailed description.

As shown in FIG. 1, the bottom wall of the lower bearing plate 11 is provided with a wear-resistant rubber layer 12, and the bottom wall surface thereof is corrugated. Four hydraulic jacks 10 are respectively arranged at four corners of the top wall of the lower bearing plate 11, the top ends of the four hydraulic jacks 10 are connected with four corners of the bottom wall of the upper bearing plate 9, a level meter 8, an identification plate 7, a controller and a buzzer alarm (not shown in the figure) are arranged on the top wall of the upper bearing plate 9, and the controller is respectively connected with the level meter 8 and the buzzer alarm. These components together form a load carrier 14, for a total of four load carriers 14. Four supports 1 (two supports 1 are shielded by the other two supports in the figure) of the detection device are respectively arranged on upper bearing plates 9 of four bearing devices 14, the upper ends of the four supports 1 are gathered together, a pulley 2 is fixedly arranged below the gathering part, a steel wire rope 3 is arranged on the pulley 2, one end of the steel wire rope 3 is connected with a heavy hammer 4, and the other end of the steel wire rope is connected with an ultra-large truck crane. This detection device comes to contact with ground through four load-bearing device 14, because every load-bearing device 14's wear-resisting rubber layer 12 self has elasticity and the diapire face is the corrugate, wear-resisting rubber layer 12 just can adapt to slight unevenness's ground through deformation to make last bearing plate 9 keep the horizontality as far as possible. The ultra-large truck crane is used as a rope pulling device to pull the other end of the steel wire rope 3 so as to lift the heavy hammer 4, and then the heavy hammer 4 is prepared to be released for engineering foundation pile strain detection.

Before the ultra-large truck crane releases the heavy hammer 4, the gradienter 8 on each upper bearing plate 9 starts to detect whether the upper bearing plate 9 is in a horizontal state, if the upper bearing plate 9 is horizontal, the support 1 does not roll, that is, the heavy hammer 4 is aligned with the top end of the pile foundation, if the upper bearing plate 9 is not horizontal, the gradienter 8 sends an adjusting signal to the controller, the controller receives the adjusting signal and controls the buzzer alarm to give an alarm, and the worker receives the alarm and adjusts the hydraulic jacks 10 of each bearing device, and the hydraulic jacks 10 respectively drive the four corners of the corresponding upper bearing plate 9 to move upwards/downwards until the four upper bearing plates 9 are all adjusted to be in the horizontal state, so that the support 1 which rolls is adjusted to the non-roll state, and the heavy hammer 4 is ensured to be aligned with the top end of the pile foundation.

However, the level gauge 8 may have an error in a special environment such as a strong magnetic field, and a worker may mistakenly assume that the upper bearing plate 9 is horizontal, and therefore another detection mechanism needs to be provided to recheck whether the upper bearing plate 9 is horizontal. Each support 1 is provided with a lifting rope 13, the lower end of the lifting rope 13 is provided with an iron block 5, and the lower end of the iron block 5 is provided with a laser emitter 6 corresponding to the marking disc 7. After the leveling instrument 8 is used for ensuring that the upper bearing plate 9 is in a horizontal state, the laser emitter 6 is started to check whether the upper bearing plate 9 is horizontal again, if the laser beam emitted downwards by the laser emitter 6 is irradiated on the central point of the identification disc 7, the fact that the upper bearing plate 9 is horizontal is indicated, if the laser beam emitted downwards by the laser emitter 6 is not irradiated on the central point of the identification disc 7, the upper bearing plate 9 is possibly not horizontal, a worker is required to check which of the leveling instrument 8 and the laser emitter 6 is in a problem, the worker needs to detect by using the leveling instrument 8 and the laser emitter 6 again after solving the problem, and the conclusion that the upper bearing plate 9 is horizontal can be made that both detections are not in a problem.

And after the conclusion is obtained, operating the ultra-large truck crane to release the heavy hammer 4, enabling the heavy hammer 4 to fall to impact the top of the foundation pile, and then operating the ultra-large truck crane to hoist the heavy hammer 4 again to reset, thereby completing the primary engineering foundation pile strain detection. After the strain detection of the engineering foundation pile is carried out for a plurality of times, workers observe and detect the state of the foundation pile, and then a detection conclusion of the strain detection of the engineering foundation pile can be obtained.

The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which are still within the scope of the claims.
