Device and method for intercepting rainwater in rainy seasons in coastal region garden

Abstract

The invention relates to a device for intercepting rainwater in rainy seasons in a coastal region garden. The device comprises a water storage tank, a filtering fence and a walking top cover, whereina waterproof liner is embedded in the water storage tank; a guide funnel and a water pump are also mounted in the water storage tank; the edge of a funnel opening of the guide funnel is mounted at a notch of the water storage tank; four walls of the guide funnel are inclined; a filtering mechanism is also arranged in a funnel neck at the lower part of the guide funnel; the walking top cover is mounted at the upper part of the water storage tank through a supporting column; the walking top cover comprises a wooden cover plate and an openable well lid; the wooden cover plate consists of wooden grating plates; the openable well lid is arranged on the wooden cover plate; and the filtering fence is also arranged between the walking top cover and the water storage tank. The invention also discloses a method for intercepting the rainwater in the rainy seasons in the coastal region garden. According to the device and the method, the rainwater can be recycled while the rainwater is intercepted,so that water resources are greatly saved.

Description

technical field [0001] The invention belongs to the technical field of interception devices, and relates to rainwater interception technology, in particular to a rainwater interception device and method in a garden in a coastal area during a rainy season. Background technique [0002] First of all, due to the severe water shortage in some areas of Tianjin, the agricultural water supply has been greatly affected. The annual rainfall in Tianjin is only 620 mm and the distribution is uneven, mainly concentrated in July and August, and other periods are especially dry in spring In summer and winter, water use will be greatly restricted. So far, due to the sharp reduction of groundwater table and groundwater and the severe overexploitation of some groundwater, the area has experienced soil subsidence, which limits the exploitation of national groundwater resources. The use of groundwater in Tianjin has been banned until 2020. Secondly, due to the intrusion of seawater, a large n...

AI Technical Summary

Problems solved by technology

[0007] In summary, in order to overcome the problem that a large amount of water cannot be buried underground due to the high groundwater level, since the distance between the groundwater level and the surface in this area is less than 2 meters, I cannot use deep wells and deep pits to The rainwater in the rainy season is collected, which makes it impossible to ensure sufficient water supply in the orchard
