Description

A rainwater ecological seepage well

technical field

The utility model relates to the technical field of seepage wells, in particular to a rainwater ecological seepage well.

Background technique

The seepage well refers to a shaft filled with coarse-grained materials such as crushed gravel and paved with an inverted filter layer, which is set up to infiltrate the water that cannot be drained from the side ditch into the underground permeable layer.

In the prior art, the Chinese patent whose notification number is CN207727716U discloses a rainwater slope combining a water storage seepage well and a flower tube, which includes a rain garden, a water storage seepage well and a flower tube. The rain garden creates a suitable environment for plant growth on poor soil or exposed rocks. The interior is filled with planting soil, and the surface of the planting soil is planted with drought- and waterlogging-tolerant vines. Although this type of rainwater slope combining water storage seepage wells and flower tubes collects and stores rainwater during rainfall, it releases rainwater during drought. Flower tubes are used to replenish water to plant roots to meet the basic survival needs of plants. However, due to the flowers and plants, it is difficult to discharge the water on the surface of the seepage well, resulting in accumulated water. Not only the accumulated water will cause damage to the vines, but also seepage It is difficult for the well to play the role of water seepage, and this problem needs to be solved urgently.

Utility model content

The purpose of the utility model is to provide a rainwater ecological seepage well which can discharge surface water conveniently.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

The staff dug the ground around the well body downward to form a shallow drainage ditch to facilitate the flow of rainwater around the well body into the well body. The staff then cover the well body with a water-permeable inspection well cover to reduce debris entering the well body, and through the permeable holes, the rainwater drained through the shallow drainage ditch can easily flow into the well body.

The utility model is further configured as follows: the two sides of the well body are respectively connected with water-permeable bellows.

By adopting the above technical scheme, the rainwater accumulated in the seepage well can be discharged through the permeable bellows, which can improve the drainage of the well body. At the same time, it can pass through the large space of the well body itself, which can facilitate the staff to enter the well body and adjust the permeable bellows. Carry out maintenance.

The utility model is further configured as: the first water-permeable geotextile is wrapped on the outside of the water-permeable bellows.

By adopting the above technical solution, the strength of the permeable bellows can be improved, and when the permeable bellows breaks unexpectedly, the first water-permeable geotextile makes it difficult for external gravel to enter the permeable bellows, and at the same time, the outside rainwater can normally enter the permeable bellows.

The utility model is further configured as follows: the outer circumference of the upper end of the well body is provided with planting soil.

By adopting the above-mentioned technical scheme and planting soil, on the one hand, the planting soil can enable the turf to grow vigorously, reducing the occurrence of sand and gravel blocking the permeable hole on the permeable inspection manhole cover due to the erosion of rainwater on the upper land, and on the other hand, the gravel and particles in the planting soil Fewer ingredients further reduce pore clogging.

The utility model is further configured as follows: a sandstone layer is arranged on the outer circumference of the lower end of the well body, and the sandstone layer is wrapped with a second water-permeable geotextile.

By adopting the above technical solution, the stability of the well body can be improved through the sandstone layer, and the sandstone has good water permeability, allowing rainwater to infiltrate into the well body from the sandstone layer. Through the water-permeable and sand-impermeable characteristics of the second water-permeable geotextile, the gravel in the sand layer is not easy to block the well body, and rainwater can smoothly enter the well body.

The utility model is further configured as follows: shrubs are arranged around the turf.

By adopting the above-mentioned technical scheme, the compactness of the soil around the infiltration well can be improved through the shrub group, and the possibility of sand and gravel infiltrating into the well body can be further reduced. And it can have the advantage of beautifying the environment through the shrub group.

The utility model is further configured as follows: the end of the shrub group away from the turf is provided with a rainwater guiding flow groove, the rainwater guiding flow groove is inclined downward toward the side of the shrub group, and the inclination degree of the rainwater guiding flow groove is 1:20.

By adopting the above-mentioned technical solution, the rainwater from farther away can be guided into the seepage well through the rainwater guiding trough, the water seepage efficiency can be improved, and the seepage range can be expanded, and the diversion efficiency can be improved through the inclined rainwater guiding trough.

The utility model is further configured as follows: the side of the rainwater guiding trough away from the shrub group is a sidewalk, the sidewalk slopes downward toward the side of the rainwater guiding trough, and the slope of the sidewalk is 2%.

By adopting the above technical scheme, through the sidewalk with a slope, the rainwater on the sidewalk can enter the rainwater guiding trough through the slope, thereby diverting the rainwater on the sidewalk, and the rainwater enters the seepage well to discharge the urban road, improving the safety of the urban road. drainage.

In summary, the beneficial effects of the utility model are:

1. The shallow drainage ditch and the permeable hole on the permeable inspection manhole cover are adopted, so as to produce the effect that the rainwater on the ground can be introduced into the seepage well;

2. The water-permeable bellows and the first water-permeable geotextile are adopted, so that the rainwater in the seepage well can be discharged, and it is also convenient for the staff to check and repair the bellows.
