Anti-cracking method for carborundum solidified terrace of basement
The invention relates to an anti-cracking method for a basement carborundum solidified floor. The anti-cracking method comprises the following steps: step 1, preparation before construction; step 2, ground milling operation; thirdly, a concrete layer is laid; fourthly, a carborundum layer is laid; 5, the expansion joint is cut and maintained; 6, laying a curing agent layer; the step 4 specifically comprises the following steps: step B1, polishing and slurry extraction: polishing and slurry extraction are carried out on the concrete layer by using a hand-held troweling machine; a super-flat floating ruler is used for conducting scraping treatment on the ground firstly, then a ruler with the length of 3 meters is used for checking the flatness of the concrete surface, the ruler is flatly placed on the concrete surface during checking, and the maximum distance between the bottom edge of the ruler and the concrete surface does not exceed 2 mm; step B3, scattering and mixing carborundum; step B4, using a troweling machine to alternately press-polish the ground horizontally and vertically until no knife mark exists on the surface; the problem that in the prior art, a basement floor is prone to cracking is solved.
本发明涉及地下室金刚砂固化地坪的防开裂方法，包括如下步骤：步骤一、施工前的准备；步骤二、地面铣刨作业；步骤三、混凝土层铺设；步骤四、金刚砂层铺设；步骤五、伸缩缝切割并养护；步骤六、固化剂层铺设；步骤四中具体过程包括如下步骤：步骤B1、打磨提浆：对混凝土层使用手扶抹光机进行打磨提浆；步骤B2、刮平：用超平刮尺先对地面进行刮平处理，再用3米长直尺检查混凝土面平整度，检查时直尺平放于混凝土表面上，直尺底边离开混凝土面最大距离不超过2mm；步骤B3、金刚砂撒播与糅合；步骤B4、使用抹光机横竖交替压光地面，直至表面没有刀印；解决了现有技术中地下室地坪容易开裂的问题。
