Artificial stratum freezing method utilizing low-temperature carbon dioxide to cyclic refrigeration
The invention relates to an artificial stratum freezing method utilizing low-temperature carbon dioxide for cyclic refrigeration. The method includes the steps of providing freezing pipes, and driving the freezing pipes into an area needing freezing construction in a stratum; providing a liquid carbon dioxide supply device, communicating the liquid carbon dioxide supply device with all the freezing pipes to form a first circulation loop, and continuously feeding liquid carbon dioxide into the freezing pipes through the liquid carbon dioxide supply device, wherein the liquid carbon dioxide in the freezing pipes is used for freezing a soil body around the freezing pipes so as to complete freezing construction of a corresponding area in the stratum. According to the artificial stratum freezing method utilizing low-temperature carbon dioxide for cyclic refrigeration, carbon dioxide can be recycled, so that the method is more economical and practical, and efficient freezing under the same cost is achieved.
本发明涉及一种利用低温二氧化碳循环制冷的人工地层冻结方法，包括：提供冻结管，将冻结管打入地层中需冻结施工的区域内；提供液态二氧化碳供给装置，将液态二氧化碳供给装置与所有的冻结管连通并形成第一循环回路，通过液态二氧化碳供给装置向冻结管内持续的送入液态二氧化碳，利用冻结管内的液态二氧化碳对冻结管周围的土体进行冻结以完成地层中对应区域的冻结施工。本申请能够循环利用二氧化碳更加经济和实用，以实现相同费用下更高效的冻结。
