A basement roof drainage construction method

This invention relates to the field of building construction technology and discloses a method for constructing drainage systems on basement roofs. The method includes the following steps: pre-treating the basement roof slab substrate; applying a waterproof coating to the pre-treated substrate; applying a waterproof membrane over the waterproof coating; laying a non-woven fabric over the waterproof membrane for isolation; pouring a protective layer over the non-woven fabric; and leaving drainage ditches on both sides of the junction between the basement roof slab and the main building, and on both sides of the post-cast strip. This invention utilizes the junction line between the basement roof slab and the main building, as well as the post-cast strip, as partition boundaries to divide the basement roof slab into several drainage areas. Within each drainage area, a slope is created from the center towards the drainage ditch, allowing water to quickly converge into the ditch. Simultaneously, the slope created by the waterproof mortar within the drainage ditch and its connection to the surrounding open ditches form a continuous drainage path, thereby significantly improving drainage efficiency and effectively avoiding water accumulation on the roof slab due to excessively long drainage paths.

Sound-absorbing porous foam concrete composite board and preparation method thereof

This invention belongs to the field of building materials technology, specifically disclosing a sound-absorbing porous foamed concrete composite board and its preparation method. Using foamed concrete as the substrate of the composite board effectively solves the problem of poor environmental performance of traditional sound insulation materials. Compared with materials such as polystyrene and sound-absorbing rock wool, it does not require a large amount of energy for preparation and can utilize recycled raw materials. It does not produce toxic powder after aging, reducing harm to the air environment and human health, while also avoiding the flammability hazards of traditional materials. The closed-cell sound insulation layer's sealed pores can block direct sound wave penetration, achieving basic sound insulation. The sound-absorbing pores of the porous sound-absorbing layer, combined with the interconnected channels, introduce incident sound waves into the interior. Energy is dissipated through reflection and friction within the channels, forming a dual protection of "sound absorption and sound insulation." This solves the core problem of poor sound insulation performance of traditional concrete and compensates for the short lifespan of traditional sound insulation materials, extending the overall service life of the board.
