Indirect annular freezing device in shield tunneling machine, installation method of indirect annular freezing device and freezing system
The invention discloses an indirect annular freezing device in a shield tunneling machine, an installation method of the indirect annular freezing device and a freezing system, and relates to the field of engineering construction. The indirect annular freezing device in the shield tunneling machine comprises a freezing pipe and a temperature measuring pipe, wherein the freezing pipe is arranged on the inner side of a shield tunneling machine shell, the freezing pipe utilizes the shield tunneling machine shell to transfer heat to carry out heat exchange on the inner side and the outer side of the shield tunneling machine shell so as to realize indirect freezing, and a freezing wall which is arranged in a circular ring shape around the outer side of the shield tunneling machine shell is formed; and the temperature measuring pipe extends into a temperature measuring hole of the freezing wall, and the depth of the temperature measuring hole is close to and not larger than the thickness of the freezing wall. According to the indirect annular freezing device, the bottom sealing water freezing of the water-containing soil layer on the outer side of the shield tunneling machine shell is realized, an annular water flowing channel along the circumference of the shell is closed, the secondary water leakage risk caused by the fact that the freezing system is implanted into the soil body after the shield tunneling machine shell is perforated from inside to outside is avoided, and the effectiveness and the safety of freezing are ensured.
本发明公开了一种盾构机内的间接环形冻结装置、其安装方法及冻结系统，涉及工程施工领域。盾构机内的间接环形冻结装置，包括：冻结管，所述冻结管布置在盾构机壳体内侧，其中冻结管利用盾构机壳体传递热量进行盾构机壳体内外两侧的热交换而实现间接冻结，形成沿盾构机壳体外侧成圆环形状环绕布置的冻结壁；以及测温管，所述测温管伸入冻结壁的测温孔内，其中测温孔的深度接近且不大于冻结壁的厚度。本发明实现盾构机壳体外侧含水土层彻底封水冻结，封闭沿壳体圆周的环形流水通道，并且避免由盾构机壳体从内至外径向开孔后向土体植入冻结系统，而伴随产生的次生漏水风险，确保冻结的有效性和安全性。
