Background

Inverted roofs are currently used in many residential and public building roofing systems because of their simple construction, their protection by placing the waterproof layer under a thermal insulation layer, and their extensive use by avoiding damage to the waterproof layer by thermal stress, ultraviolet rays and other factors. The slope finding layer in the inverted roof structure is generally made of materials for slope finding, such as foam concrete, ceramsite and the like, gaps in the materials are more, if the construction period is rainy, accumulated water in the slope finding layer is more, most of the leveling layer is leveled by mortar, and easily cracked and seeped water enters the slope finding layer; the waterproof layer is arranged on the leveling layer, accumulated water is still between the roof and the waterproof layer after construction is finished, and the problems of waterproof hollowing and the like are easily caused when the accumulated water is vaporized in high-temperature weather. Usually, only surface layer drainage is considered in the drainage measures, but accumulated water in the slope finding layer is not considered, roof leakage water is inevitably caused for a long time, the maintenance is difficult after the problem of the leakage water occurs, and the later maintenance cost is high. The traditional mode of solving the problem of looking for slope layer ponding at present is for opening the hole drainage at the floor, treats to carry out waterproof shutoff to the wash port after the drainage is accomplished, and the processing procedure drainage latency is longer, influences the construction of decorating, and whether the later stage shutoff infiltration has certain risk.
