Ground anti-cracking construction method
The invention discloses a ground anti-cracking construction method. The ground anti-cracking construction method comprises the steps that cement mortar is adopted for leveling a ground base layer to form a leveling layer; after leveling is achieved, water is sprayed to the leveling layer within 12-24 hours, and the surface of the leveling layer is covered with a layer of thin film so as to reduce water evaporation; and the thin film is uncovered after the cement mortar is solidified. Compared with the prior art, after the cement mortar is used for leveling the ground base layer, the water is sprayed to the leveling layer so that the cement mortar can be fully wetted, the surface of the leveling layer is covered with the layer of thin film, it is guaranteed that the water is not prone to evaporation, and cement has enough time to solidify; and the quality problems of cracking, dusting and the like of a cement mortar layer in the later period due to too fast water evaporation after cement mortar leveling are effectively prevented, so that ground cracks are effectively avoided.
本发明公开了一种地面防开裂施工方法，包括：采用水泥砂浆对地面基层进行找平形成找平层；找平后在12‑24小时内对找平层洒水，并在找平层表面盖上一层薄膜，以减少水分蒸发；待水泥砂浆凝固后揭开薄膜。与现有技术相比，本发明在采用水泥砂浆对地面基层进行找平后对找平层洒水，以让水泥砂浆充分湿润，并在找平层表面盖上一层薄膜，保证水分不容易蒸发，让水泥有足够的时间凝固，有效防止了水泥砂浆找平后由于水分蒸发过快造成后期水泥砂浆层出现开裂起砂等质量问题，从而有效避免地面裂缝的产生。
