1. Precautions for Qingdao Protective Siphon Drainage Collection System
The following problems should be paid attention to in the application of siphon rainwater drainage system. Control of the water depth before the bucket. The water depth in front of the bucket is too small to effectively form a siphon full pipe flow, the system cannot operate in the siphon state, and the drainage capacity cannot meet the design requirements. The water depth in front of the bucket is too large, which will increase the load on the roof and bring hidden dangers to the safety of the structure. It may be necessary to increase the strength of the structure, which will increase the construction cost. A layer of filtering non-woven geotextile is laid on the top surface of the conical projection platform to prevent the passage of soil particles, thereby avoiding the blockage of the drainage channel and making the channel drainage smooth. The traditional drainage method of the roof of the garage uses bricks and stones as the filter layer, and uses more pebbles or gravel as the filter layer, and drains the water to the designated place. The use of concave-convex filter plates to replace the cobblestone filter layer to drain water saves time, effort and energy, saves investment, and can also reduce the load on the building.

2. The relationship between Qingdao protective siphon drainage collection system and sponge city
There is no relationship between siphon drainage and sponge city, siphoning is just a way of pipeline layout, and there is no essential difference from normal pipeline layout. Only in some places where the straight water pipe is inconvenient, siphoning is considered. In the sponge city construction project, Tai'an adheres to the water management concept of "water saving priority, spatial balance, systematic governance, and two-handed effort", and effectively reduces flood hazards through measures such as "seepage, retention, storage, purification, use, and drainage". Purify the water environment, alleviate the urban heat island effect, and restore the urban ecology. "Sponge cities have good flexibility in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, seeps, and purifies water, and it releases and uses the stored water when needed.

3. Qingdao protective siphon drainage collection system and garage
1. Clean up the site after the garage roof is finished, paste the waterproof membrane, lay the foam protective layer, and clean the site before laying the Penglian drainage board. There should be no obvious bumps and other construction garbage to ensure that the garage roof is flat.
2. After the drainage board is laid, lay a plastic grid, also called a plastic support net. The general color is green. It is used between the drainage board and the non-woven geotextile to support the non-woven fabric and ensure that the non-woven fabric is filtered. The water achieves the best results.

4. Qingdao protective siphon drainage collection system
Traditional drainage methods can no longer fully meet the needs of modern buildings, and the application of siphon rainwater systems is an effective solution to the problem of large-area roof drainage in modern buildings. Siphon drainage technology has high promotion value and broad development prospects. In the early 1990s, the domestic construction industry began to adopt siphon rainwater systems. Especially in a number of large-scale projects, such as factories, airports, stadiums, exhibition halls and other buildings, the practical applications have achieved good drainage effects, and the system has been Running well.
