如中国专利CN205369740U公开的一种pds零坡度防护虹吸排水收集***，包括高分子防护排水异型片、虹吸排水槽、变径管道、观察井以及集水井，高分子防护排水异型片和虹吸排水槽铺设在房屋结构上，高分子防护排水异型片和虹吸排水槽上方还设有土工布，虹吸排水槽顶部连接有透气观察管，虹吸排水槽通过变径管道与观察井连通，观察井通过管道与集水井连通，集水井的上部还连接有集水透气观察管。而通常建筑物顶板(如车库顶板)面积较大，在铺设虹吸排水槽时，为了便于高分子防护排水异型片层的渗透水的排出，不仅需要在建筑物顶板的四周布置排水槽，建筑物顶板的中部位置也需要铺设排水槽，不仅施工复杂，工期长，而且虽然设置较多排水槽，但排水效果不佳。且施工过程中或渗透水中不可避免的有一定量小块泥沙泥土到排水板排水空间内造成排出水内带有泥沙，但***没有可靠措施保证泥沙泥土不进入到蓄水池，造成收集用水品质较差，不利于用于浇灌种植屋面的植被，此外，没办法收集屋顶和地面的水，不能充分利用建筑小区所有雨水。For example, a pds zero-slope protection siphon drainage collection system disclosed in Chinese patent CN205369740U includes polymer protection drainage special-shaped sheets, siphon drainage grooves, variable diameter pipes, observation wells and water collection wells, and polymer protection drainage special-shaped sheets and siphon drainage grooves are laid In the house structure, geotextiles are also arranged above the polymer protective drainage special-shaped sheet and the siphon drainage groove. The top of the siphon drainage groove is connected with a ventilation observation pipe. The water well is connected, and the upper part of the water collecting well is also connected with a water collecting and ventilating observation pipe. In general, the roof of a building (such as a garage roof) has a large area. When laying a siphon drainage groove, in order to facilitate the discharge of the seepage water of the polymer protective drainage special-shaped sheet, it is not only necessary to arrange drainage grooves around the roof of the building. Drainage grooves also need to be laid in the middle of the roof, which is not only complicated to construct and has a long construction period, but also that although there are many drainage grooves, the drainage effect is not good. In the construction process or in the infiltrated water, a certain amount of small pieces of silt and soil inevitably enter the drainage space of the drainage board, resulting in sediment in the discharged water, but the system has no reliable measures to ensure that the silt and soil do not enter the reservoir, resulting in the collection of sediment. The water quality is poor, which is not conducive to irrigating the vegetation on the roof. In addition, there is no way to collect the water on the roof and the ground, and all the rainwater in the building area cannot be fully utilized.

The straight pipe section forms a full flow, which accelerates the discharge of infiltrated water on the drainage board, and at the same time, the number of side drainage rainwater buckets is added to improve the water output capacity. On the other hand, the water collecting tank is no longer arranged in the middle position, which reduces the consumption of the water collecting tank in principle, shortens the construction period and reduces the construction cost on the basis of the existing system.
(2)虹吸管采用偏心变径与直管段连接的方式，形成更好的水力工况，进一步加快虹吸管的满管，从而进一步提升排水速度。(2) The siphon pipe adopts the method of eccentric variable diameter and straight pipe connection to form a better hydraulic working condition, and further accelerate the full pipe of the siphon pipe, thereby further improving the drainage speed.
(3)由虹吸管排入沉淀井内的水先经沉淀后再经隔板溢流后进入回收水模块，提高回收水的品质，同时回收水模块还回收小区楼层屋顶的雨水，回收的水可用于浇灌植被层的植物，实现小区雨水资源的再生利用，节约水资源。(3) The water discharged into the sedimentation well by the siphon is first precipitated and then overflows through the partition, and then enters the reclaimed water module to improve the quality of the reclaimed water. At the same time, the reclaimed water module also recycles the rainwater on the roof of the community floor, and the recovered water can be used for watering Plants in the vegetation layer can realize the regeneration and utilization of rainwater resources in the community and save water resources.
