PASTED FREEZING PIPE AND FITTING METHOD THEREOF

PROBLEM TO BE SOLVED: To provide a freezing pipe that can be fitted on a structure readily and reliably, and a fitting method for the freezing pipe.SOLUTION: A freezing pipe (1) according to the present invention includes a flow channel through which a secondary coolant flows, the secondary coolant being a liquefied gas. The freezing pipe includes a flat plate-form member having a plurality of microscopic coolant flow channels formed thereon as flow channels through which the secondary coolant flows directly (1A: a microchannel). The flat plate-form member (1A) is made of a light-weight and highly flexible material that offers excellent thermal property in relation to diffusion of cold heat and absorption of hot heat (for example, aluminum). The freezing pipe is fitted on a structure (such as a rear barrel part of a shield machine or a tunnel lining segment).SELECTED DRAWING: Figure 2 【課題】構造物に容易且つ確実に取り付けることが出来る凍結管と、当該凍結管の取付工法の提供。【解決手段】本発明の凍結管（１）は、二次冷媒が流れる流路を有し、当該二次冷媒は液化ガスであり、二次冷媒が直接流れる流路として複数の微小冷媒流路が設けられた扁平な板状部材（１Ａ：マイクロチャンネル）を有し、扁平な板状部材（１Ａ）は軽量で可撓性に富み、冷熱の放散ならびに温熱の吸収に関与する熱特性に優れる材料（例えばアルミニウム）で構成され、構造物（例えばシールド機の後胴部或いはトンネル覆工用セグメント）に取り付けられる。【選択図】図２
