Construction process of lateral-rigidity detection system for long-spiral post-inserted cage cast-in-place piles
The invention discloses a construction process of lateral-rigidity detection system for a long-spiral post-inserted cage cast-in-place piles. By the adoption of the fiber bragg grating sensing technology, in the long-spiral post-inserted cage construction process, a stable and effective displacement transducer test system is designed and fixed to the outer sides of the walls of steel reinforcement cages, displacement meters are evenly arranged on an optical fiber measuring line, and data collection ports are safely led out to the upper portions of the construction working faces through protective sleeves. By means of the method, stress strain data of pile foundations are measured stably and effectively in real time, meanwhile the lateral rigidity of pile bodies can be monitored effectively, and stable and effective real-time data information is provided for the safety evaluation of underground engineering.
