Embodiment Construction
[0019] The rigid waterproof construction method for beam-slab basement of the present invention comprises the following steps:
[0020] (1) Infiltrate the surface of the clean and flat concrete base;
[0021] (2) The clean water and cement-based infiltration crystalline waterproof coating are uniformly prepared into mortar at a weight ratio of 0.3:1, and the preparation process must be completed within 20 minutes; the total amount of mortar is within the specified amount. On the construction area, according to 1.4kg / m 2 amount to calculate;
[0022] (3) Use brushes and nylon brushes to evenly brush the mortar on the surface of the infiltrated concrete base, or use a spray gun to spray evenly until the mortar is used up; when painting or spraying, the ambient temperature must be above 4 ℃;
[0023] (4) 3-4 hours after the final setting of the mortar, use spray water for curing, and spray water for curing 3-5 times a day for 2-3 consecutive days.
[0024] In the above step (3...
