Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building high anti-seepage roof drainage structure. Background Technique

[0002] Roof greening refers to gardening on the roofs, terraces, rooftops, balconies of various buildings and structures, or large artificial rockery mountains, and planting trees and flowers. Roof greening can not only effectively insulate the roof, but also beautify the environment, purify the air, and improve the local microclimate. At the same time, it can also enrich the vertical and horizontal landscapes of the city, compensate for the greening ground occupied by buildings, and greatly improve the urban greening rate. It is a roofing form that is being vigorously promoted. However, there are many problems with roof greening. The plant roots will damage the waterproof layer, resulting in water accumulation, and the drainage is not smooth, leading to damage to the roof structure. Therefore, a building high anti-seepage roof drainage structure has been developed. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a building high anti-seepage roof drainage structure to solve the problems pointed out in the above background technique.

[0004] In order to achieve the above utility model purpose, the following technical solutions are further adopted:

[0005] A building high anti-seepage roof drainage structure includes a waterproof layer provided on the roof main structure. A plurality of strip-shaped leveling pads are arranged at intervals on the waterproof layer, and a heat preservation layer is filled between two adjacent strip-shaped leveling pads. A plurality of water storage tanks are arranged on the strip-shaped leveling pads, and waterproof sealing materials are provided on the contact surface between the strip-shaped leveling pads and the water storage tanks, and between two adjacent water storage tanks. A plurality of water storage tanks are connected through siphon pipes, and the water levels of the water storage tanks can always be kept consistent. A cover plate is provided on the top of the water storage tank, and holes are opened on the cover plate. A plurality of support columns are arranged inside the water storage tank. A geotextile water filtration layer is provided on the cover plate, and a planting soil layer is provided on the geotextile water filtration layer. A main pipe is also horizontally arranged on the waterproof layer, the main pipe is connected to a drain pipe, the drain pipe is installed on the roof main structure, the main pipe is connected to a siphon rainwater bucket through a branch pipe, the siphon rainwater bucket is arranged on one side of the planting soil layer, and the branch pipe is connected to an overflow pipe arranged on the water storage tank. When the rainfall is small, the rainwater enters the water storage tank from the planting soil layer for storage and is used for watering plants; when the rainfall is large, the rainwater is discharged to the drain pipe through the siphon rainwater bucket; when the water level of the water storage tank is about to be full, it enters the branch pipe through the overflow pipe and is discharged to the drain pipe through the main pipe.

[0006] As a further improvement of the utility model, the strip-shaped leveling pad is a concrete pad.

[0007] As a further improvement of the utility model, the support column is an arc-shaped column.

[0008] As a further improvement of the utility model, the waterproof layer is a polyvinyl chloride waterproof coiled material.

[0009] As a further improvement of the utility model, a plurality of the water storage tank bodies are arranged along the length direction of the strip-shaped leveling cushion block.

[0010] The beneficial effects of the utility model are as follows: The water storage tank body of the high anti-seepage roof drainage structure is arranged in a suspended manner between the roof main structure, which plays a role in waterproofing and anti-seepage, and at the same time can achieve the functions of heat preservation and energy conservation. The high anti-seepage roof drainage structure can solve the problem of local water accumulation of rainwater in the planting soil layer, realize drainless drainage, avoid plant necrosis, and at the same time can provide water source for plant irrigation to achieve energy conservation and environmental protection. The siphonic drainage generates a siphonic phenomenon when the rainfall is large, and the flow velocity of rainwater in the pipe increases to achieve rapid drainage. Compared with the gravity drainage under the same conditions, the diameter of the drainage pipe can be reduced, saving materials. BRIEF DESCRIPTION OF THE DRAWINGS
