Referring to fig. 1, the system for monitoring and protecting the stress of the steel pile on line comprises a plurality of measuring units and a display and calculation unit 41. Wherein, each measuring unit sets up along piling bar 31 length direction, and measuring unit is provided with monitoring components 20, and in this embodiment, as shown in fig. 2, measuring unit totally two and set up from top to bottom along piling bar 31 length direction. The steel pile 31 is in operation fixed to the hull 32 by means of two measuring units.

Specifically, the measuring unit is provided with monitoring subassembly 20, and monitoring subassembly 20 includes a plurality of hydraulic component that arranges around the circumference of piling bar 31, and hydraulic component includes hydraulic cylinder 21 and is used for measuring pressure sensor 22 of hydraulic cylinder 21 pressure, and hydraulic cylinder 21 one end is connected with piling bar 31, specifically hydraulic cylinder 21 piston rod supports presses on piling bar 31, as shown in fig. 1.

The connecting point of the hydraulic oil cylinder 21 and the steel pile 31 is defined as a pressure measuring point, the pressure measuring point in the upper measuring unit and the corresponding pressure measuring point in the lower measuring unit are arranged up and down along the length direction of the steel pile 31, as shown in fig. 1, the pressure measuring points of the two measuring units are projected along the axial direction of the steel pile, and are coincident. In this embodiment, four hydraulic rams 21 are provided for each monitoring assembly 20, and are evenly distributed around the circumference of the steel pile 31.

It can be understood that the pressure measuring point in the upper measuring unit, the pressure measuring point in the lower measuring unit and the bottom end of the steel pile 31 form three points for balancing stress, and through the lever principle, the three points are balanced in stress and the stress presents a proportional relation. Meanwhile, the three points of relative displacement strokes show a proportional relation, the stress condition of the steel pile 31 can be calculated through calculation, specifically, each pressure sensor 22 is electrically connected with the display and calculation unit 41, the pressure of the hydraulic oil cylinder 21 is measured through each pressure sensor 22, and data is fed back to the display and calculation unit 41 to be calculated and displayed.

The setting of the pressure of the compressed air in the energy accumulator can be designed according to the pressure requirement of the steel pile on specific projects so as to form a steel pile stress monitoring and protection range of the safety stress.

When the on-line steel pile stress monitoring and protecting system works, each control valve 24 is closed, the steel pile 31 is stressed to form deviation, and corresponding hydraulic oil cylinders 21 form deviation displacement, because the oil cylinder displacement of the hydraulic oil cylinders 21 can cause the pressure in the corresponding energy accumulators 23 to change, and the pressure in the energy accumulators 23 is transmitted to the display and calculation unit 41 through the pressure sensor 22 to be calculated and displayed.
