Real-time monitoring method for stress distribution of steel piles

Abstract

The application belongs to the technical field of civil engineering, and provides a structure for real-time monitoring of stress distribution of steel piles and an installation method thereof. The structure for real-time monitoring of the stress distribution of steel piles includes steel piles, stress or strain gauges, wires, wire protection steel, etc.; steel piles include several segmental piles connected sequentially from bottom to top; Stress or strain gauges; the steel piles are installed outside the steel pile, and the wire protection steel and the outside of the steel pile together form a wire channel; the bottom of the wire channel is also installed with a head plate; several wires are respectively installed in the wire channel, and The lower ends of the wires are connected to the stress or strain gauges one by one, and the upper ends of the wires are located outside the top of the wire channel. This application is applicable to single-section, especially multi-section steel piles, and can be applied to various splicing methods, including factory splicing and on-site splicing; Effective protection, the technical solution is simple, reliable and effective.

Description

technical field [0001] The application belongs to the technical field of civil engineering, and in particular relates to a structure for real-time monitoring of stress distribution of steel piles and an installation method thereof. Background technique [0002] During and after pile sinking, it is usually necessary to monitor the stress distribution of steel piles in real time. However, due to the fact that the pile foundation penetrates into soil layers with different densities and strengths during the pile formation process, it poses a severe challenge for the protection of the pile stress monitoring components and their conductors, especially for long piles composed of multi-section piles. Monitoring, due to pile connection operation, further increases the difficulty of implementation and reduces the feasibility of effectively protecting test components and wires. [0003] Stress or strain gauges have been widely used in stress monitoring of components related to enginee...

Problems solved by technology

However, its application to steel piles has the following characteristics: 1. Steel piles are usually hollow pipe piles, the wall thickness of the steel pipe is relatively thin, and the stress or strain gauge is pasted on the pipe wall. 2. The stress or strain gauge needs to be connected to the wire to be connected to the collector on the ground. The wire is also easily disconnected by the friction between the soil and the pile; 3. The longer steel pile Generally, it is made of multi-sections. Due to construction operations such as hoisting and welding of various piles on site, the protection of the wires at the splicing parts is particularly important and difficult; During the process, it is easy to damage the stress or strain gauges and wires on the pile joints to be sunk
