Horizontal local freezing pipe
The horizontal local freezing pipe comprises a freezing pipe body, a heat insulation and isolation assembly and a liquid supply pipe, the freezing pipe body is arranged in a stratum, the heat insulation and isolation assembly is installed in the freezing pipe body and attached to the inner wall face of the freezing pipe body in a sealed mode, and the liquid supply pipe is inserted into the freezing pipe body and penetrates through the heat insulation and isolation assembly. A gap for saline water to flow back is formed between the liquid supply pipe and the heat insulation and isolation assembly, and a gap for saline water to flow back is also formed between the end of the liquid supply pipe and the pipe bottom of the freezing pipe. The freezing pipe is divided into the freezing section and the non-freezing section by arranging the heat insulation and isolation assembly, when low-temperature saline water is circulated, the non-freezing section prevents cold energy from being released into the soil layer on the outer side, the effect of controlling the freezing position is achieved, meanwhile, the cold energy can be saved, and the freezing construction requirement of the accurate position can be met; the two are matched with each other, so that the blocking effect can be improved to the greatest extent.
本发明公开水平局部冻结管，包括冻结管、绝热隔离组件和供液管，所述冻结管设置在地层内，所述绝热隔离组件安装在冻结管内，且所述绝热隔离组件与所述冻结管的内壁面密封贴合，所述供液管插入所述冻结管内并穿过绝热隔离组件，所述供液管和所述绝热隔离组件之间具有供盐水回流的缝隙，所述供液管的端部与所述冻结管的管底之间也具有供盐水回流缝隙。本发明，通过设置绝热隔离组件，将冻结管分为冻结段和非冻结段，在低温盐水进行循环时，在非冻结段阻隔冷量向外侧土层中释放，起到控制冻结位置的效果，同时能够节省冷量，能够满足精确位置的冻结施工需求，通过设置真空层和保温层，两者相互配合，能够最大程度的提高阻隔效果。
