Local difference freezing pipe capable of controlling freezing section and applied to freezing construction
The invention relates to the technical field of artificial stratum freezing method construction of underground engineering, in particular to a local difference freezing pipe capable of controlling a freezing section and applied to freezing construction. The freezing pipe comprises an upper control freezing section, a lower control freezing section, a partition device, a liquid inlet pipe, a liquid return pipe and a control valve; and different valves are controlled, and the flowing path of low-temperature refrigerant in the freezing pipe is controlled. According to the local difference freezing pipe, selective freezing can be achieved, the defect that a traditional freezing pipe can only conduct whole-section freezing is overcome, controlled freezing of stratums with different layer depths can be achieved, the freezing efficiency of the freezing pipe is improved, a freezing area and the freezing section can be controlled, various construction requirements and engineering actual working condition requirements are met, and the working efficiency is improved. The local difference freezing pipe has the outstanding characteristics of being easy to operate, high in construction practicability, excellent in economical efficiency and the like, and has high application and popularization value.
本发明涉及一种地下工程的人工地层冻结法施工技术领域，更具体地，涉及一种应用于冻结施工中的可控制冻结段的局部差异冻结管。所述的冻结管包括：上部控制冻结段、下部控制冻结段、隔断装置、进液管、回液管以及控制阀门。通过不同阀门的控制及低温冷媒在冻结管内的流动路线控制。本发明可以实现选择性冻结，避免传统冻结管只能全段冻结的缺点，本发明可以实现对不同层位深度地层的控制冻结，提高了冻结管的冻结效率，可以做到控制冻结区域及冻结段，满足了各种施工要求及工程实际工况需要，提高工作效率。本发明操作简单，施工实用性强，经济性优越等突出特点，具有较大的推广应用价值。
