Active cooling construction device and method for cast-in-situ bored pile in permafrost region
The invention discloses an active cooling construction device and method for a cast-in-situ bored pile in a permafrost region, and the device comprises a refrigeration cycle system, a temperature monitoring module, a temperature analysis module and a refrigerant control module. The temperature monitoring module monitors an initial temperature field of soil around the cast-in-situ bored pile and temperature field changes in the drilling, pouring and maintenance processes in real time; the temperature analysis module is used for analyzing and processing data measured by the temperature monitoring module, calculating the conveying and circulating speed required by the refrigerant control module, and estimating and evaluating the cooling effect of the cooling construction device and the running time required for achieving the target cooling effect; and the refrigerant control module controls the conveying circulation rate of the refrigerant in the refrigeration circulation system and the continuous running time of the circulation, so that a complete circulation of temperature monitoring, temperature analysis and refrigerant control is completed. The construction period and efficiency of the project can be shortened, the initial bearing capacity of the frozen soil pile foundation is improved, and the follow-up construction project can be promoted.
本发明公开了一种多年冻土区钻孔灌注桩主动冷却施工装置及方法，所述装置包括制冷循环系统、温度监测模块、温度分析模块和制冷剂控制模块，温度监测模块实时监测钻孔灌注桩周土的初始温度场以及钻孔、灌注和养护过程中的温度场变化；温度分析模块对温度监测模块测得的数据进行分析处理，计算出制冷剂控制模块所需的输送及循环速率，并预估评价该冷却施工装置的冷却效果和达到目标冷却效果所需的运行时间；制冷剂控制模块控制制冷剂在制冷循环系统中的输送循环速率及循环持续的运行时间，至此完成温度监测、温度分析及制冷剂控制的一个完整循环。本发明可缩短工程建设周期和效率，提高冻土桩基初期承载力，有利于推进后续的施工工程。
