[0037] The present invention provides a construction method of an antique rammed earth wall surface structure, comprising the following steps:

[0038] S1. After cleaning the base layer of the wall 1, lay the glass fiber mesh 2 on the base layer.

[0039] During the base treatment, the wall surface is polished to remove protrusions and impurities on the wall to ensure the flatness of the wall surface; then, the wall surface is cleaned to ensure that the wall surface is dry and dust-free.

[0040] After the base layer is treated, the fiberglass mesh is hung on the wall.

[0041] S2. Lay an anti-cracking mortar layer 3 on the base layer so that the anti-cracking mortar layer 3 covers the glass fiber mesh 2.
