Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an eccentric variable diameter full flow device of a siphon drainage system on a roof of an underground garage. Background Art

[0002] Large basement rooftops are susceptible to severe water stagnation due to rain and snow. When water accumulates on the garage roof, the pressure exerted on the existing waterproofing can cause cracks at the joints. Water can then seep into the basement through these cracks, leading to water seepage. Furthermore, the presence of water in the soil can cause plant roots to remain submerged for extended periods, potentially causing root rot and impacting the survival of outdoor greenery.

[0003] The traditional gravity drainage system has shortcomings such as multiple pipe settings, large space occupation and complex construction. The siphon drainage system can significantly speed up the drainage by utilizing the potential energy of building height and ground drop to form a siphon effect.

[0004] The existing utility model patent document with announcement number CN212772690U discloses a garage roof siphon drainage system. By setting a siphon drainage channel and a siphon pipe under the vegetation layer, the water gathered on the garage roof is guided to be discharged through the variable diameter siphon effect, changing the previous passive drainage method to active siphon drainage, realizing zero-slope active drainage of the planting area of the garage basement roof, increasing the drainage speed, preventing leakage on the garage roof, and having strong practicality.

[0005] Although the above-mentioned garage roof siphon drainage system can solve the corresponding technical problems, the siphon drainage diameter change of its siphon pipe is a concentric diameter change, which makes it difficult to generate a linear flow, thereby reducing the siphon drainage effect.

[0006] Therefore, an eccentric variable diameter full flow device for the siphon drainage system of the underground garage roof is proposed. Utility Model Content

One end of the second large-diameter pipe close to the second small-diameter pipe is integrally formed with a second reducer pipe. The center of the left side of the second reducer pipe is concentric with the center of its right side.

[0012] As a preferred technical solution, the water collection mechanism includes a polymer drainage sheet arranged on the concrete basement garage roof. The edge of the polymer drainage sheet has a drainage groove, and one end of the first large-diameter pipe away from the first reducer pipe is communicated with the drainage groove.

[0013] As a preferred technical solution, the drainage groove is a U-shaped groove with an opening facing downwards, and the side wall of the drainage groove is provided with a water inlet adapted to the polymer drainage sheet.

[0014] As a preferred technical solution, a filter layer is jointly laid on the top of the polymer drainage sheet and the drainage groove. The filter layer is geotextile.

[0015] As a preferred technical solution, a waterproof layer is arranged between the bottom of the polymer drainage sheet and the concrete basement garage roof. The waterproof layer is fixedly connected to the concrete basement garage roof, and the waterproof layer is an SBS modified asphalt waterproof coiled material.

[0016] As a preferred technical solution, the first large-diameter pipe is in an L-shaped structure, the first small-diameter pipe is in a U-shaped structure, the second small-diameter pipe is in a Z-shaped structure, the first small-diameter pipe and the second small-diameter pipe have the same diameter and form an S-shaped structure, and the first large-diameter pipe, the first reducer pipe, the first small-diameter pipe, the second small-diameter pipe, the second reducer pipe, and the second large-diameter pipe are connected end to end in sequence.

[0017] As a preferred technical solution, the sedimentation mechanism includes a sedimentation well communicated with one end of the second large-diameter pipe away from the second reducer pipe, and a manhole cover is installed at the top end of the sedimentation well.

[0018] The utility model at least has the following beneficial effects:
