Ruins leaving behind structure service restoration preservation method

摘要

PURPOSE: To prevent a ruin and a remains construction from damage and discoloration caused by organisms such as mildews and mosses and to keep the restored condition for a long time by performing restoring and preservation of the ruin and the remains construction by a method wherein a soil layer constituting them is divided into layers each with a specified thickness from the bottom and a soln. of a specified silicone compd. is scattered on the surface of each layer when the ruin and the remains construction are adjusted, restored and preserved. ;CONSTITUTION: A soil layer constituting a ruin and a remains construction is dug out and according to a measured figure, a soil layer with a thickness of 1-50cm is formed as a lowermost layer and a water soln. of a polysiloxane-polyoxyalkylene block copolymer is scattered on the surface. After the same works are repeated thereon, an uppermost layer with a thickness of 1-50cm is formed. On this surface, a soln. of a polyalkylene glycol-added silicone compd. (PGS) or a curable silicone compd. is also scattered in parallel with the above described water soln. A compd. of formula I is pref. as the PGS. In the formula, m is 0-10; n is 1-10; x is 2-6; y is 3-10 and z is 0-1 and A is selected from H, CH₃, C₂H₅, C₃H₇, COCH₃ and COC₂H₅.;COPYRIGHT: (C)1993,JPO&Japio
