Abstract

The invention discloses a pile temperature and deformation measuring transparent soil testing device for an energy pile group and a testing method of the testing device. The device comprises an optical platform, a lifting support and a transparent model groove; an end bearing groove is fixed in the model groove; the model groove is filled with transparent soil; a model pile is buried in the transparent soil and corresponds to the model groove; and a bearing platform is connected with the pile group. an infrared thermal imager, a CCD industrial camera and a laser transmitter are all connected to the lifting support in a sliding mode and arranged on the periphery of the model groove; and an infrared thermal imager is also arranged over the model groove. The pile testing device for the energy pile group is easy and convenient to operate, economical and feasible, and has high innovativeness. The testing device can simulate four engineering conditions of an end bearing pile-pile group low bearing platform, an end bearing pile-pile group high bearing platform, a friction pile-pile group high bearing platform and a friction pile-pile group low bearing platform, realizes full-coverage monitoring of a pile-soil temperature field and a displacement field, and provides reference for research of thermodynamic characteristics of the pile foundations of the energy pile groups.

Description

technical field [0001] The invention relates to the field of civil construction engineering, in particular to an energy pile group pile temperature-deformation measurement transparent soil test device and a test method thereof. Background technique [0002] With my country's rapid urbanization process, the scale of the construction industry continues to expand, and the proportion of building energy consumption continues to increase. The HVAC system accounts for a large proportion of building energy consumption. Therefore, the development of new energy technologies and the reduction of HVAC system energy consumption have become the key to reducing building energy consumption. As a clean and renewable energy, geothermal energy can effectively increase the proportion of non-fossil energy and reduce the energy consumption of traditional air conditioners. [0003] The development of geothermal energy is mainly based on the traditional ground source heat pump technology, that is,...
