Problems solved by technology
[0002] At present, the difficulty faced in the protection of cultural relics is how to ensure that the restoration work does not destroy the original surface of the cultural relics? How to effectively play the function of cultural relics after restoration? How to clean up the current repairs without affecting the original grassroots when more advanced repair technologies appear in the later stage? This is what we call reversibility. At the same time, the load of the building cannot be increased too much due to the repair work, so as to ensure that the cultural relics are "restored as old".

Embodiment Construction
[0014] Depend on Figure 1 As can be seen, the present invention comprises the following steps:
[0015] The first step is to set the treatment layer (2) on the damaged hard base layer (1);
[0016] The second step is to bond the isolation layer (3) on the treatment layer (2);
[0017] The third step is to smear the protective layer (4) on the isolation layer (3);
[0018] The fourth step is to set the surface layer (5) on the protective layer (4).
[0019] 1. The first step:
[0020] The present invention firstly cleans the damaged hard base (1) of the original building, and then applies the permeable crystalline waterproof material of the treated layer (2), which is waterproof, breathable, deeply infiltrating, freeze-thaw resistant, and does not change the visual appearance , No damage to the original hard base (1) and other characteristics.
[0021] The construction process of this layer is:
[0022] 1) The construction surface should be kept dry, and the humidity shou...

A lossless and reversible repairing method of a damaged hard basic layer relates to a repairing method of a damaged hard basic layer in the civil work repair engineering, in particular to a lossless and reversible repairing method of a damaged hard basic layer in the protection of modern historical relics. The method comprises the following steps: 1. setting a processing layer (2) on a damaged hard basic layer (1); 2. bonding a separating layer (3) on the processing layer (2); 3. adhering a protective layer (4) on the separating layer (3); and 4. setting a surface layer (5) on the protective layer (4). The invention can effectively protect the basic layer surface of historical relics, not damage the original basic layer (1) and ensure that the historical relics can satisfy the normal operating requirements; and when a more advanced technical scheme appears, the existing repair can be removed through the separating layer (3) and the original features of the historical relics can be recovered so that the repairing scheme is reversible.
Description
technical field [0001] The invention relates to a method for repairing damaged hard bases in civil repair projects, in particular to a non-destructive and reversible repair method based on damaged hard bases in the protection of modern cultural relics. Background technique [0002] At present, the difficulty faced in the protection of cultural relics is how to ensure that the restoration work does not destroy the original surface of the cultural relics? How to effectively play the function of cultural relics after restoration? How to clean up the current repairs without affecting the original grassroots when more advanced repair technologies appear in the later stage? This is what we call reversibility. At the same time, the load of the building cannot be increased too much due to the repair work, so as to ensure that the cultural relics are "repaired as old". Contents of the invention [0003] The purpose of the present invention is to deal with the problems in the back...
