Embodiment 1

[0048] This embodiment provides a dual-system roof drainage system, such as figure 1 shown, which includes:

[0049] The siphon drainage mechanism uses the siphon principle to remove accumulated water; the siphon drainage mechanism in this embodiment includes: a water guide channel 6 arranged on the parapet 5, and a water guide channel 6 arranged on the parapet 5 away from the roof overhanging eaves 1 The roof slope-finding layer 8 on one side; the roof slope-finding layer 8 communicates with the siphon drainage pipeline 3 through the water guide channel 6; is 1 percent;

[0050] The roof independent rainwater drainage mechanism includes: a sump 2 arranged on the roof overhang 1, and the sump 2 is arranged at the edge of the outer contour of the roof overhang 1;

[0051] Both the siphon drainage mechanism and the roof independent rainwater drainage mechanism are drained through mutually independent siphon drainage pipelines 3 and eaves drainage pipes 4; the sump 2 is connect...

Abstract

The invention discloses a dual-system roof drainage system. The dual-system roof drainage system comprises a siphon type drainage mechanism and a roof independent rainwater drainage mechanism, wherein the siphon type drainage mechanism is used for draining accumulated water through the siphon principle; the roof independent rainwater drainage mechanism comprises a water collection pit formed in a roof cornice; the siphon type drainage mechanism and the roof independent rainwater drainage mechanism are used for draining water through a siphon drainage pipeline and a cornice drainage pipe which are independent of each other; the water collection pit is communicated with the cornice drainage pipe. By adopting the dual-system roof drainage system, the problems that the drainage capacity cannot meet the rainfall capacity in extreme weather since a roof drainage system in the prior art adopts a single system for draining water, and drainage is not performed in time since the siphon drainage system cannot achieve the siphon effect under the general rainfall condition are solved effectively.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a dual-system roof drainage system. Background technique [0002] In recent years, extreme rainstorms have increased year by year. The existing drainage system cannot timely absorb the large-scale water accumulation on the roof caused by short-term heavy rainfall, which has a negative impact on the durability of the roof waterproof layer and the bearing capacity of the roof structure. Moreover, the scale of rainfall in recent years has far exceeded the previous 100-year rainstorm data. For example, the rainfall of Zhengzhou 7.20 rainstorm exceeded 200mm in one hour, and exceeded 700mm in 24 hours, exceeding the historical highest rainfall data of most meteorological stations. Due to the above reasons, there are design gaps in the design standards of the current roof drainage system, and it is difficult to ensure sufficient drainage capacity of the roof in very extreme w...
