High-temperature unstable permafrost premelting and vacuum preloading reinforcing system and method
The invention provides a high-temperature unstable permafrost pre-melting and vacuum preloading reinforcing system and method, the system comprises a pre-melting unfreezing device, a sealing system and a steam generator, and the sealing system and the steam generator are both connected with the pre-melting unfreezing device. The steam generator is matched with the pre-melting and unfreezing device, high-temperature unstable permafrost is pre-melted through steam convection and heat conduction, the pre-melting and unfreezing efficiency is improved, meanwhile, the pre-melting and unfreezing device has the advantage of being environmentally friendly, and no adverse effect is generated on follow-up engineering construction. The sealing system is matched with the pre-thawing and unfreezing device to achieve drainage consolidation of the high-temperature unstable permafrost foundation, the situation that the unfreezing pipe and the soil body are disengaged due to consolidation deformation is prevented, the pre-thawing and unfreezing efficiency is guaranteed, the problem of uneven subsidence caused by repeated freezing and thawing cycles is solved, the poor property of frozen soil is changed, and the stability of the foundation is effectively improved.
本发明提供了一种高温不稳定多年冻土预融及真空预压加固系统及加固方法，该系统包括预融解冻装置、密封系统以及蒸汽发生器，所述密封系统和蒸汽发生器均与预融解冻装置连接。本发明通过蒸汽发生器与预融解冻装置配合，利用蒸汽对流和热传导来预融高温不稳定多年冻土，提高了预融解冻效率的同时具有绿色环保的特点，对后续工程建设无不良影响。通过密封系统与预融解冻装置配合实现高温不稳定多年冻土地基排水固结，防止了固结变形使解冻管和土体脱空，保证了预融解冻效率，消除了反复冻融循环造成的不均匀沉陷问题，改变了冻土不良性质并有效提高了地基稳定性。
