After the anchor bolt 8 is inserted into the indicator tube 2, the anchor bolt 8 penetrates the sealing membrane 3 and the base plate 1 and is anchored in the outer wall 5. The thermal insulation slurry in the sealed cavity is coated on the anchor bolt 8 and solidified to form the thermal insulation sealing layer 4.
