Pile body strain monitoring device

The utility model discloses a pile body strain monitoring device belongs to pile foundation pile body self strain monitoring device in experimental. The device is divided by chassis, outer sleeve, inner skleeve and the monitoring pole four bibliographic categories and forms. It is central on the chassis to monitor the pole welding, and the endotheca barrel casing is on the monitoring pole, and theovercoat barrel casing is established on the inner skleeve and is welded on the chassis, and sold stowing is difficult for permeating water, seeping water the material between outer sleeve and the inner skleeve, the outer sleeve passes through the iron wire ligature and on the pile body steel reinforcement cage, monitors the peak of the staff butt welding and receive on the pile body steel reinforcement cage. The utility model provides a pile foundation to the different section strain monitoring's of pile body monitoring devices, satisfies pile body strain monitoring device's theoretical requirement in being experime
