If it is necessary to install the inclined wire (D), it should be done after the support wires (3) are installed.

[0041] After the installation of the support device for laying the thermal insulation material in the foundation pit is completed, the sliding fixing device (2), the support line (3), the connecting sleeve (4) and the inclined wire (D) are checked, and then the thermal insulation material (A) is laid on the support line (3) as needed.
