具体实施方式Detailed ways

以下结合附图及实施例对本实用新型进行详细说明。The utility model is described in detail below in conjunction with accompanying drawings and embodiments.

参见图1,一种下凹绿地雨水利用与收集系统,其绿地系统由自下而上依次设置的砾石层9、砂层8、人工填料层7、种植土层6、枯枝落叶降解层5、挡水堰4构成,砾石层9中设置集水穿孔管10,集水穿孔管10连接雨水再利用处理装置。Referring to Fig. 1, a rainwater utilization and collection system for sunken green land, the green land system consists of a gravel layer 9, a sand layer 8, an artificial filler layer 7, a planting soil layer 6, and a litter degradation layer 5 arranged sequentially from bottom to top 1. The water retaining weir 4 is composed of a water-collecting perforated pipe 10 arranged in the gravel layer 9, and the water-collecting perforated pipe 10 is connected to a rainwater reuse treatment device.

挡水堰4是由鹅卵石或者其他的一些大石块构成的一个蓄水凹槽,蓄水深度为300mm;作用:挡水堰4为暴雨提供暂时储存的空间,降雨时让雨水优先滞留于挡水堰4内,通过植物的作用过滤雨水,同时将雨水中的沉淀物留在此处;虽然挡水堰4深度增加,储水能力越强,但挡水堰4深度增加需要较高的渗透能力,又不利于植物生长,所以选择蓄水深度为300mm最佳。The water retaining weir 4 is a water storage groove formed by cobblestones or other large stones, and the water storage depth is 300mm; function: the water retaining weir 4 provides a temporary storage space for the rainstorm, and the rainwater is preferentially retained in the retaining wall when it rains. In the water weir 4, the rainwater is filtered through the action of plants, and the sediment in the rainwater is left here at the same time; although the depth of the water retaining weir 4 increases, the water storage capacity is stronger, but the increase of the depth of the water retaining weir 4 requires higher infiltration capacity, and it is not conducive to plant growth, so it is best to choose a water storage depth of 300mm.

为防止雨水过多时溢出下凹绿地,在挡水堰4的高水位线处设有溢流管1,将溢流管1连接室外蓄水池19,并在溢流管1的一端包裹纱布2,以防溢流管1堵塞。溢流管1可以选择PVC塑料管或者PPR管,纱布2选用稀网纱布。In order to prevent excessive rainwater from overflowing the concave green space, an overflow pipe 1 is provided at the high water level of the weir 4, and the overflow pipe 1 is connected to the outdoor reservoir 19, and one end of the overflow pipe 1 is wrapped with gauze 2 , in case the overflow pipe 1 is blocked. Overflow pipe 1 can choose PVC plastic pipe or PPR pipe, and gauze 2 can choose thin mesh gauze.

枯枝落叶降解层5是种植土层6上种植好植物后,在种植土层6上部和植物根部之间铺设的一层80mm左右厚的枯枝及一些植物的叶子、松树秆、木头屑片和碎木材;枯枝落叶降解层5可以提供良好的微生物环境,有利于微生物的生长和有机物的降解,进一步对雨水净化,同时可以保持土壤的湿度,避免表层土壤板结而造成渗透性能降低,而且还有助于抵抗径流雨水的侵蚀防止水土流失。The litter degrading layer 5 is a layer of about 80mm thick dead branches and some plant leaves, pine stalks, and wood chips laid between the top of the planting soil layer 6 and the roots of the plants after the plants are planted on the planting soil layer 6. and broken wood; the litter degradation layer 5 can provide a good microbial environment, which is conducive to the growth of microorganisms and the degradation of organic matter, further purifies the rainwater, and can maintain the humidity of the soil at the same time, avoiding the reduction of the permeability of the surface soil due to compaction, and It also helps to resist the erosion of runoff rainwater and prevent soil erosion.

种植土层6是在人工填料层7上平铺的一层厚度约为50cm、渗透系数较大的本地区的砂质土壤,其主要成分中砂子的含量为60%~85%,有机成分含量为5%~10%,黏土含量不超过5%。这样有助于雨水的下渗、保证透气性以及植物更快的适应当地的生长环境。种植土层6的具体厚度可根据选种的植物类型而定。The planting soil layer 6 is a layer of sandy soil with a thickness of about 50 cm and a relatively large permeability coefficient spread on the artificial filler layer 7. The content of sand in its main components is 60% to 85%, and the content of organic components 5% to 10%, and the clay content does not exceed 5%. This helps infiltration of rainwater, ensures air permeability, and allows plants to adapt to the local growth environment faster. The specific thickness of the planting soil layer 6 can be determined according to the type of plant selected.

人工填料层7是在砂层8上方铺设的一层由渗水砖、空心砖或大石块等构成的渗透性较强的天然或人工材料,再添加沙、锯末、木屑等有机质;人工填料层7厚度选取100cm左右为宜;人工填料层7既可支撑种植土层6,又可通过填料层的物理、化学和其中微生物综合作用削减径流污染,防止种植土层6随雨水一起流走。The artificial filler layer 7 is a layer of natural or artificial materials with strong permeability composed of seepage bricks, hollow bricks or large stones laid above the sand layer 8, and then add organic matter such as sand, sawdust, wood chips, etc.; the artificial filler layer 7 The thickness is preferably about 100cm; the artificial filler layer 7 can not only support the planting soil layer 6, but also reduce runoff pollution through the physical, chemical and microbial comprehensive effects of the filler layer, and prevent the planting soil layer 6 from flowing away with the rainwater.

砂层8是在砾石层9上方平整放置的一层粗粒石子等,厚度大约为15cm左右;砂层8可以防止土壤颗粒进入砾石层9堵塞集水穿孔管10,同时还能起到通风的作用。The sand layer 8 is a layer of coarse-grained stones placed flatly above the gravel layer 9, with a thickness of about 15 cm; the sand layer 8 can prevent soil particles from entering the gravel layer 9 to block the water collection perforated pipe 10, and can also play a role in ventilation. effect.

砾石层9是在挖好的坑的底部平整放置一层鹅卵石,作为底层基础,用于净化后雨水的汇集和排出。在砾石层9内,用三根PVC塑料管作为集水穿孔管10连接成三通管形式,两根塑料管水平放置,一根竖直放置,水平放置的塑料管的雨水汇集到竖直塑料管中,最后由竖直管将汇集到砾石层9的所有雨水排出。两根水平放置的塑料管与底部之间要有一定的距离,且在两根水平管壁的上半部分、竖直管壁四周打出许多小孔11并用砂布包裹,既便于雨水进入集水穿孔管10,又防止底部泥沙进入集水穿孔管10。The gravel layer 9 is to place a layer of pebbles flatly at the bottom of the dug pit as the bottom foundation for collecting and discharging rainwater after purification. In the gravel layer 9, use three PVC plastic pipes as the water collection perforated pipe 10 to connect into a three-way pipe form, two plastic pipes are placed horizontally, and one is placed vertically, and the rainwater from the horizontally placed plastic pipes is collected into the vertical plastic pipes In the end, all rainwater collected in the gravel layer 9 is drained by vertical pipes. There must be a certain distance between the two horizontally placed plastic pipes and the bottom, and many small holes 11 are punched in the upper half of the two horizontal pipe walls and around the vertical pipe walls and wrapped with emery cloth, which is convenient for rainwater to enter the water collection perforation Pipe 10 prevents the bottom silt from entering the water-collecting perforated pipe 10 again.

另外,在下凹绿地的四周可以建造几条植草沟3,以将更多的雨水引进来,还可以增加美观性。In addition, several grass planting ditches 3 can be built around the sunken green space to introduce more rainwater and increase the aesthetics.

仍参见图1,雨水再利用处理装置包括由沉砂池12、消毒池14、储水池16等设施组成,沉砂池12、消毒池14、储水池16由输水管道依次连接,沉砂池12的雨水进口连接集水穿孔管10,沉砂池12与消毒池14之间的输水管道上设置泥沙过滤装置13,消毒池14与储水池16之间的输水管道上设置过滤网15,储水池16设有水泵17和溢流口18。Still referring to Fig. 1, the rainwater reuse treatment device comprises facilities such as a grit chamber 12, a disinfection pond 14, and a water storage tank 16. The rainwater inlet of 12 is connected to the water collecting perforated pipe 10, the sediment filter 13 is arranged on the water delivery pipeline between the grit chamber 12 and the disinfection tank 14, and the filter screen is arranged on the water delivery pipeline between the disinfection tank 14 and the water storage tank 16 15. The water storage tank 16 is provided with a water pump 17 and an overflow port 18.

雨水再处理工艺流程为:雨水→沉砂池12→管道→泥沙过滤装置13→消毒池14→管道→储水池16→提升泵17→用作其他用途。收集后的水通过沉砂池12进行首次过滤,再通过泥过滤装置13对雨水进行再处理,处理后的水在消毒池14进行消毒,可采用氯片作为消毒剂,最后经两头设有过滤网15的管道汇入储水池16(设有溢流口18),通过提升泵17进行提升利用。The process flow of rainwater reprocessing is: rainwater→grit chamber 12→pipeline→sediment filter device 13→disinfection pond 14→pipeline→water storage tank 16→lift pump 17→used for other purposes. The collected water is filtered for the first time through the grit chamber 12, and then the rainwater is reprocessed through the mud filter device 13. The treated water is disinfected in the disinfection tank 14. Chlorine tablets can be used as a disinfectant, and finally filtered through two ends. The pipeline of the net 15 flows into the water storage tank 16 (with an overflow port 18), and is lifted and utilized by a lift pump 17.

雨水经再次的简单处理后,可用于对水质要求不高的用途实现雨水的重复循环利用,例如可用于绿化浇灌用水,市政道路浇洒用水,洗车用水等。After simple treatment again, the rainwater can be used for reuse and recycling of rainwater for purposes that do not require high water quality, such as water for greening, water for municipal roads, water for car washing, etc.
