THERMAL INSULATION CONSTRUCTION METHOD FOR WALL SURFACE OF LOW-TEMPERATURE TANK

摘要

PROBLEM TO BE SOLVED: To provide a thermal insulation construction method for the wall surface of a low-temperature tank or the like capable of eliminating the use of an existing spacer or minimizing the use to reduce the number of steps, shorten a construction period of time, reduce a construction cost, and saving labor, and capable of constructing a well-finished thermal insulation layer.;SOLUTION: When the thermal insulation layer 6 of a unit width is constructed by filling and foaming urethane liquid concentrate in a urethane filling space 9 between a surface material 5 and the wall surfaces 2 of a wall body 1 such as the low-temperature tank while sequentially delivering the surface material 5 by the raising traveling of a construction machine A, one end open part 9b of the space 9 is closed by the side face of a preceding PUF6', and the other end open part 9a is closed by a releasable surface material 15 sequentially delivered from the construction machine A side to prevent the leakage of the urethane liquid concentrate.;COPYRIGHT: (C)2004,JPO
