Abstract
The invention discloses a floor slab waterproof protective layer construction method. First, foundation beam structure construction is conducted. In the foundation beam structure construction, grooves are formed in the two sides of a foundation beam cushion layer. Bottoms of two cement slab templates are respectively inserted in the groove in the corresponding side. The construction steps after the foundation beam structure construction is finished are as following: (1) detaching inner supporting wood beams; (2) laying waterproof roll layers so as to form side wall waterproof roll layers, a foundation beam cushion layer waterproof roll layer and a base plate cushion layer waterproof roller layer; (3) respectively installing fixing cement slabs on the inner side wall of the side wall waterproof roller layers on the left side and the right side; (4) forming an inner support; (5) pouring foundation beam waterproof protection layer concrete on the foundation beam waterproof roll layer, and pouring base plate waterproof protection layer concrete on the base plate cushion layer waterproof roller layer. The vertical face water protection layer formed by the adoption of the method is firm, stable, and not easy to come off, and plays an effective role in protecting the waterproof layer in base plate construction.
