Anti-water-seepage prefabricated slab construction method
The invention discloses an anti-water-seepage prefabricated slab construction method. The method comprises a prefabricated frame formed by enclosing prefabricated beams, and a prefabricated slab overlapped in the prefabricated frame, wherein a detachable loading mechanism for loading downwardly from the upper surface of the prefabricated slab is arranged on the middle part of the prefabricated slab; the fixing end of the loading mechanism is fixedly connected to the prefabricated beams; the load output end of the loading mechanism is pressed against the upper surface of the prefabricated slab; load is applied through the loading mechanism in order that the middle part of the prefabricated slab is deformed downwardly, and the circumference of the corresponding prefabricated slab is deformed towards the middle part of the prefabricated slab, so that pouring gaps are formed between the circumference of the prefabricated slab and corresponding prefabricated beams; micro-expansion concrete is poured into the pouring gaps, and the loading mechanism is removed after the cured micro-expansion concrete reaches certain strength, so that end cracking of the prefabricated slab is avoided.
