Abstract

The utility model relates to a rain water collecting device for an exposed ground, which is characterized in that the utility model comprises a principal well (4), an assistant well (1), a water filtering layer (3). The principal well has a dank well wall with a diameter between 60cm and 100cm and a silo pitshaft with a depth between 10m and 30m. The assistant well has the dank well wall with a diameter between 20cm and 30cm and the silo pitshaft with a depth between 5 m and 10m. A well mouth of the principal well is arranged on the ground with a well cover (5) at the well mouth and the well mouth of the assistant well is provided with a dank hedge cover (2), the distance between the assistant well and the assistant well or between the assistant well and the principal well being from 8m to 20m. The well mouth of the assistant well is provided with a permeable layer (3) with a width between 20 cm and 30 cm and a thickness between 20 cm and 30 cm, which communicates the principal well and the assistant well. The distance between the exposed ground and the soil layer (6) is from 30cm to 50 cm and the permeable layer is arranged under the soil layer (6). The utility model is fit for the leakage and the collection of the rain water for the city exposed ground, which has the advantages of reasonable structure, convenient construction, low cost and good effect.

Description

Bare ground rainwater collection facilities

technical field

The utility model belongs to an urban rainwater treatment facility, in particular to a rainwater collection facility on the bare ground in the city, which is used to prevent the rainwater from flooding because the rainwater cannot penetrate into the ground in time when the rainwater is concentrated, so as to ensure that the rainwater infiltrates into the ground in time and can be collected for supply Reuse.

Background technique

In order to expand the area of greening in the city, it is necessary to reserve a large amount of bare ground for planting trees and grass. These bare grounds generally have no sewer facilities, and the rainwater only depends on the ground soil to infiltrate into the ground naturally. When the rainwater is relatively concentrated, the seepage capacity of the bare ground cannot make the rainwater infiltrate into the ground in time, which often causes rainwater to flood, and a large amount of muddy water rushes into the streets, roads and residential areas, causing urban pollution. For this reason, it is necessary to propose a rainwater treatment facility to solve the problem of preventing the flooding of rainwater on the bare ground in the city.

Utility model content

The purpose of this utility model is to address the above problems and propose a rainwater collection facility on bare ground, which can make rainwater infiltrate into the ground in time, and can be collected for reuse.

The purpose of this utility model is solved by the following technical solutions: a rainwater collection facility on the bare ground, characterized in that it is mainly equipped with a main well, an auxiliary well, and a water-permeable layer, and the main well is permeable to the well wall, with a diameter of The vertical shaft is 60-100cm long and 10-30m deep, and the auxiliary shaft is a vertical shaft with a permeable wall, a diameter of 20-30cm, and a depth of 5-10m. Manhole cover, the wellhead of the auxiliary well is provided with a permeable hedge cover. A 30cm permeable layer, which connects the main well and the auxiliary well, is set under the soil layer 30-50cm deep on the bare ground.

One main well is set on the ground in the range of 100 square meters, and 10-30 auxiliary wells are set around each main well.

Because the utility model is provided with the main well, the auxiliary well and the sump, and the permeable layer is arranged between the main well and the auxiliary well, the auxiliary well and the permeable layer are covered with a relatively thin soil layer, so that the rainwater can penetrate quickly Underground, it is concentrated into the auxiliary well and the main well through the permeable layer, which can avoid the flooding of rainwater; the water stored in the auxiliary well can slowly infiltrate into the main well or deep underground; open the manhole cover of the main well, you can easily access the concentrated water The rainwater is used for watering flowers and trees. The utility model has the advantages of reasonable structure, convenient construction, low cost, good effect of infiltrating rainwater and concentrating rainwater, preventing flooding of rainwater, and facilitating rainwater reuse.
