Freezing pipe for freezing reinforcement in tunnel construction
The freezing pipe comprises a flow choking sleeve, a rubber sleeve is arranged in the flow choking sleeve in a sleeved mode, and a flow guide hole is formed in the bottom of an inner cavity of the flow choking sleeve in a drilling machine tapping mode; and a matching sleeve is fixedly mounted at the position, located outside the flow blocking sleeve, of one end of the flow guide hole in a welding manner. The matching sleeve is matched with the conical seat, one end of the conical seat extends into the flow guide hole, so that an inner cavity of the flow blocking sleeve is communicated with an inner cavity between the outer pipeline and the inner pipeline, a refrigerant flows in a containing cavity between the flow blocking sleeve and the inner pipeline, in the process, the refrigerant does not make direct contact with water, the refrigerant can cool the water firstly, and then the refrigerant flows into the containing cavity between the outer pipeline and the inner pipeline. And the cooled water cools the soil, and the cooling mode can prevent the refrigerant from being in direct contact with the pipeline on the outermost side, so that the safety performance of the device is improved.
本申请公开了一种用于隧道施工冷冻加固的冷冻管，包括阻流套筒，阻流套筒内部套设有橡胶套管，所述阻流套筒内腔的底部通过钻床开孔的方式开设有导流孔，所述导流孔的一端位于阻流套筒外部的位置上通过焊接的方式固定安装有配合套筒。配合套筒与锥形座相配合，锥形座的一端伸入导流孔的内部，使得阻流套筒的内腔与外管道和内管道之间的内腔相连通，冷冻剂在阻流套筒和内管道之间的容腔中流动，在该过程中，冷冻剂与水并不直接接触，冷冻剂会先对水进行降温，经过降温的水在对土壤进行降温，这种降温方式可避免冷冻剂直接与最外侧的管道直接接触，提高了该装置的安全性能。
