Description
技术领域technical field
本发明涉及环境保护领域，特别涉及一种不透水地面雨水导渗系统。The invention relates to the field of environmental protection, in particular to an impermeable ground rainwater infiltration system.
背景技术Background technique
由于现代城市多采用釉面砖、水泥、沥青等不透水的材料铺设地面，使得人工不透水地面在城市面积中所占的比例越来越大，因此，城市人工不透水地面的扩大将城市地面以上和地面以下分成两个完全不同的环境体系。对于地面以上的环境系统，以排水系统为主，使得径流系数增大，在相同降雨量情况下，洪峰较早出现，洪峰流量也急剧增加。当遇到较大的降雨量时，其流量可能超过城市排水系统的承受能力，造成城市内涝，对城市道路交通系统、房屋财产损失、城市公共卫生等造成较大的威胁。对于地下环境系统，不透水地面的增加，雨水滞留在地上形成地表径流或经排水系统流入江河，地下水得不到适时补充，加上工业生产和现代生活成倍抽取地下水，造成地下水位急剧下降，加剧了城市的干旱、缺水、地面沉降等问题。此外，由于不透水地面的阻隔，当大量雨水落到地面上时，只能白白的流走，而与此同时，处于不透水地面下方的土层以及绿化带中的土层却由于长期不能得到充足的地面雨水补给，造成缺水状态，对于绿化带中的草木，还需经常额外动用喷淋设备进行水量补给，造成了城市水资源的大量消耗。Since modern cities often use impermeable materials such as glazed bricks, cement, and asphalt to lay the ground, the proportion of artificial impermeable ground in the urban area is increasing. Therefore, the expansion of urban artificial impermeable It is divided into two completely different environmental systems from the ground below. For the environmental system above the ground, the drainage system is the main one, which increases the runoff coefficient. Under the same rainfall, the flood peak appears earlier, and the flood peak discharge also increases sharply. When encountering a large amount of rainfall, its flow may exceed the bearing capacity of the urban drainage system, causing urban waterlogging, and posing a greater threat to the urban road traffic system, housing property loss, and urban public health. For the underground environment system, the increase of impermeable ground will cause rainwater to stay on the ground to form surface runoff or flow into rivers through the drainage system. The groundwater cannot be replenished in a timely manner. In addition, industrial production and modern life double the groundwater, resulting in a sharp drop in the groundwater level. Aggravated the city's drought, water shortage, land subsidence and other problems. In addition, due to the barrier of the impermeable ground, when a large amount of rainwater falls on the ground, it can only flow away in vain. Sufficient ground rainwater supply leads to a state of water shortage. For the vegetation in the green belt, it is often necessary to use additional sprinkler equipment for water supply, resulting in a large consumption of urban water resources.
为了改善城市大规模铺设人工不透水地面所带来的不利影响，将雨水导入城市地下土体，还原原有生态系统，采取措施补充地下水，同时减轻城市排水压力，是城市水生态环境改善的必然途径。对于城市建设，可以在城市道路、广场的硬铺装下适当预埋地面雨水渗流系统，减少对原有土地、自然环境的冲击，有利于创建绿色城市、生态城市。In order to improve the adverse effects caused by laying artificial impermeable ground on a large scale in cities, it is inevitable to improve the urban water ecological environment by introducing rainwater into the urban underground soil, restoring the original ecosystem, taking measures to replenish groundwater, and at the same time reducing the pressure on urban drainage. way. For urban construction, the ground rainwater seepage system can be pre-buried under the hard pavement of urban roads and squares to reduce the impact on the original land and natural environment, which is conducive to the creation of green cities and ecological cities.

具体实施方式detailed description
下面结合附图，对本发明的一个具体实施方式进行详细描述，但应当理解本发明的保护范围并不受具体实施方式的限制。A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
参见1、图2，本发明实施例提供了一种不透水地面雨水导渗系统，包括雨水口1，所述雨水口1顶部设有水篦子7，雨水口1中部的侧壁上开设有与排水通道连通的排水口8，所述雨水口1下部的侧壁上开设有导水口6，所述导水口6与埋设于不透水地面下方土层9中的导水管道2连通，所述导水管道2与若干个设于不透水地面下方土层9中的渗水井3相连通，且若干个渗水井3之间也通过导水管道2相连通；所述渗水井3内填充有鹅卵石5或者下放有筒壁密布有若干渗水孔10的井筒。在下雨时，雨水流进雨水口1后，首先通过导水口6流入导水管道2，进而流入渗水井3中，从而能够对不透水地面以下的土层补水，当雨水继续增多时，雨水口中的水位会逐渐升高至排水口8的高度，甚至超过排水口的高度，则多余的雨水会通过与排水口相连通的排水通道进入城市排水系统。因此，本实施例的不透水地面雨水导渗系统不但分流了部分雨水，而且能够对不透水地面以下的土层起到很好的补水作用。因此，本实施例很好地实现将雨水导渗入不透水地面以下的土层，提高了城市区域整体的蓄水量，并可有效减少降雨对城市防洪、排水措施的压力，同时对城市绿化带土壤中的水分补给也起到了显著的作用，减少了绿化用水，节约了城市水资源。Referring to Fig. 1 and Fig. 2, the embodiment of the present invention provides an impermeable ground rainwater infiltration system, comprising a gully 1, the top of the gully 1 is provided with a water grate 7, and the side wall in the middle of the gully 1 is provided with a The drainage outlet 8 connected by the drainage channel, the side wall of the lower part of the rainwater outlet 1 is provided with a water guide 6, and the water guide 6 communicates with the water guide pipe 2 buried in the soil layer 9 under the impermeable ground.

When it rains, after the rainwater flows into the rainwater outlet 1, it first flows into the aqueduct 2 through the water guide opening 6, and then flows into the seepage well 3, so that the soil layer below the impermeable ground can be replenished. When the rainwater continues to increase, the water in the rainwater outlet The water level will gradually rise to the height of the drain outlet 8, and even exceed the height of the drain outlet, then excess rainwater will enter the urban drainage system through the drainage channels connected with the drain outlet. Therefore, the impermeable ground rainwater infiltration system of this embodiment not only diverts part of the rainwater, but also plays a good role in replenishing water to the soil below the impermeable ground. Therefore, this embodiment realizes well that rainwater is guided and infiltrated into the soil layer below the impermeable ground, improves the overall water storage capacity of the urban area, and can effectively reduce the pressure of rainfall on urban flood control and drainage measures, while improving urban green belts.

进一步地，所述渗水井3的井口位于不透水地面的地基垫层4的下方，且井口覆盖有混凝土盖板11。通过混凝土盖板11可以起到很好的支撑作用，避免了由于渗水井的存在导致地面不稳固。Further, the wellhead of the seepage well 3 is located under the foundation cushion 4 on the impermeable ground, and the wellhead is covered with a concrete cover 11 . The concrete cover 11 can play a very good supporting role, avoiding the instability of the ground due to the existence of seepage wells.
进一步地，所述渗水井3的内径为120cm-180cm、井深为3-8米。对渗水井的直径做合理的设计可以避免由于渗水井内径太大造成地面支撑力度减弱，或者由于内径太小导致渗水不畅的问题。Further, the inner diameter of the seepage well 3 is 120cm-180cm, and the well depth is 3-8 meters. Reasonable design of the diameter of the seepage well can avoid the weakening of ground support due to too large inner diameter of the seepage well, or the problem of poor water seepage due to too small inner diameter.

进一步地，所述水篦子7的上表面与不透水地面的地面层12的上表面持平，便于雨水流入雨水口。Further, the upper surface of the water grate 7 is flat with the upper surface of the ground layer 12 of the impermeable ground, which is convenient for rainwater to flow into the rainwater outlet.
进一步地，所述雨水口1下部的侧壁上开设有多个导水口6，所述导水口6的孔径均为50mm，所述导水管道2的内径也为50mm，所述导水口6内插接有与所述导水管道2相对接的连接管件。Further, a plurality of water guides 6 are provided on the side wall of the lower part of the rainwater outlet 1, the apertures of the water guides 6 are all 50 mm, and the inner diameter of the water guide pipe 2 is also 50 mm. A connecting pipe fitting connected to the water guide pipe 2 is plugged in.
进一步地，所述导水管道2是PVC管道，PVC管道成本低且耐腐蚀，经久耐用。Further, the water guide pipe 2 is a PVC pipe, which is low in cost, corrosion-resistant and durable.

进一步地，所述井筒采用混凝土材料制成，使用混凝土材料其成本低，且坚固耐用，支撑力度强。Further, the shaft is made of concrete material, which is low in cost, durable and strong in support.
进一步地，所述井筒外包裹有土工布，可以避免土壤长期在水流的作用下堵塞渗水孔10。Furthermore, the shaft is wrapped with geotextiles, which can prevent the soil from blocking the seepage holes 10 under the action of water flow for a long time.
综上所述，本发明依据水文学、水力学、水利工程构造等基本原理，提供一种不透水地面雨水导渗系统，其改造了城市现有的雨水井及排水系统，设计了相应的雨水渗透系统，能够很好地实现将雨水导渗入不透水地面以下的土层，提高了城市区域整体的蓄水量，并可有效减少降雨对城市防洪、排水措施的压力，同时对城市绿化带土壤中的水分补给也起到了显著的作用，减少了绿化用水，节约了城市水资源。In summary, the present invention provides an impermeable surface rainwater infiltration system based on the basic principles of hydrology, hydraulics, and hydraulic engineering structures.
