Description

Technical Field

[0001] The invention relates to the field of water drainage and storage structures, in particular to a multi-bucket water drainage and storage integrated system for a basement top plate landscape green belt. Background Art

[0002] At present, with the acceleration of urbanization, land resources are becoming increasingly scarce. As an important part of urban buildings, the space utilization and environmental protection of basements are receiving more and more attention. Traditional basement roofs often lack effective greening and drainage measures, which makes it difficult to green the roofs and restricts plant growth. At the same time, poor rainwater management can easily cause roof leakage and structural safety problems. Therefore, it is particularly important to develop a basement roof landscape greening system that can achieve greening and beautification and effectively manage rainwater.

[0003] Existing, the bottom of the drainage ditch installed on the basement ceiling is usually installed with buckets at intervals, and a riser is installed at the corresponding position of each bucket, so that after rainwater enters the drainage ditch, it flows into the riser through the bucket and finally flows into the collection pool for collection.

[0004] With regard to the above-mentioned related technologies, since the distances between the water buckets in the drainage ditch are too long, the drainage path is long and the drainage speed is slow. Summary of the invention

[0005] In order to improve the drainage efficiency of the drainage ditch, the present application provides a multi-bucket integrated drainage and storage system for the basement roof landscape green belt.

[0006] The present application provides a multi-bucket integrated drainage and water storage system for a basement roof landscape green belt, which adopts the following technical solutions:

[0008] By adopting the above technical solution, during drainage, a group of multiple water buckets are set at the same drainage position in the drainage ditch. The water flows into the branch pipe through the water bucket for collection, and finally flows into the vertical pipe to complete the overall drainage, which can greatly improve the drainage efficiency; and through the cooperation of the same group of water buckets, branch pipes and vertical pipes, a siphon principle can be formed to further improve the discharge of water in the drainage ditch.

[0009] Preferably, the ratio of the cross-sectional area of ​​the branch pipe to the cross-sectional area of ​​the riser is 1:3-1:2.

[0010] By adopting the above technical solution, the cross-sectional area of ​​the branch pipe is designed to be smaller than the cross-sectional area of ​​the riser, which can speed up the flow rate of rainwater in the pipe and improve drainage efficiency.

[0011] Preferably, the riser is located in the middle of the branch pipe.

[0012] By adopting the above technical solution, the paths of each water bucket flowing to the riser are made more uniform, thereby improving the drainage efficiency.

[0014] By adopting the above technical solution, the two-layer waterproof membrane can achieve a stronger waterproof effect, reduce the water seepage rate, and thus protect the basement.

[0015] Preferably, water drainage and storage boards are laid between the road layer and the waterproof base layer, and between the planting layer and the waterproof base layer.

[0016] By adopting the above technical solution, the drainage and storage board replaces the traditional pebbles as the drainage layer, which can store part of the rainwater. While satisfying the drainage function, it can keep the soil moist, ensuring sufficient water for plant growth, so that its roots can quickly take root downwards and firmly take root in the soil.

[0017] Preferably, a geotextile filter layer is laid on the side of the drainage and storage board away from the waterproof base layer.

[0018] By adopting the above technical solution, the soil can be isolated and the water permeability can be guaranteed, the stability of the overall structure is enhanced, and it helps to prevent the movement and settlement of the soil.

[0019] Preferably, flower walls are laid between the drainage ditch and the road layer, and between the drainage ditch and the planting layer.

[0020] By adopting the above technical solution, the overall strength of the drainage ditch can be enhanced and the service life of the drainage ditch can be increased.

[0021] Preferably, a supporting groove is provided at the bottom of the drainage ditch and at the position corresponding to each water bucket, and a plug-in rod is circumferentially arranged on the supporting groove; the flange of the water bucket is clamped in the supporting groove, and a plug-in hole is provided on the flange of the water bucket for the plug-in rod to pass through.

[0022] By adopting the above technical solution, the flange of the water bucket is clamped in the supporting groove, and the plug-in rod is plugged into the plug-in hole, thereby completing the installation and positioning of the water bucket; this installation method is easy to operate and highly practical.

[0023] Preferably, a pebble drainage layer is laid on the top of the drainage ditch.

[0024] By adopting the above technical solution, the gaps between the pebbles can effectively promote the penetration and flow of water, so that the drainage capacity of the drainage ditch is significantly improved; and the pebbles are not easily blocked by debris, which can keep the drainage ditch unobstructed for a long time.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. During drainage, a group of multiple water buckets are set at the same drainage position in the drainage ditch. The water flows into the branch pipe through the water bucket for collection, and finally flows into the vertical pipe to complete the overall drainage, which can greatly improve the drainage efficiency;

[0027] 2. The drainage and storage board replaces the traditional pebbles as the drainage layer, which can store some rainwater, and keep the soil moist while satisfying the drainage function, ensuring sufficient water for plant growth, so that the roots can quickly take root downwards and firmly take root in the soil;

[0028] 3. The flange of the water bucket is clamped into the supporting groove, and the plug-in rod is plugged into the plug-in hole to complete the installation and positioning of the water bucket; this installation method is easy to operate and highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
