Ecological conservation water-saving device for urban agglomeration green land

Abstract

The invention relates to an ecological conservation water-saving device for urban agglomeration green land. The ecological conservation water-saving device comprises a cylindrical shell with the overall section in a regular hexagon shape, an infiltrating irrigation unit is arranged on the upper portion of the cylindrical shell, a first water storage unit is arranged in the center of the infiltrating irrigation unit, and at least one second water storage unit communicating with the first water storage unit in sequence is arranged at the lower part of the first water storage unit; and the ecological conservation water-saving device for the urban agglomeration green land further comprises a first water conveying pipe network communicating with the first water storage unit, a second water conveying pipe network communicating with each second water storage unit and a third water conveying pipe network arranged in the infiltrating irrigation unit. Irrigation water, rainfall and the like are collected and stored, slow release is conducted when water is needed in the green land, the irrigation time and frequency are remarkably shortened, the purposes of efficiently utilizing rainwater, reducing rainwater runoff, effectively increasing groundwater supply and saving water resources are achieved, and the important effect of the urban green land in sponge city construction is fully played.

Description

technical field [0001] The invention relates to the fields of garden maintenance, rainwater collection and utilization, sponge city construction and the like, and in particular relates to an ecological conservation and water-saving device for green spaces in urban agglomerations. Background technique [0002] With the acceleration of urbanization, urban green space, as an important green infrastructure, has important ecological functions in improving the quality of urban ecological environment, reducing urban heat island effect, regulating and storing rainwater, and adjusting urban ecological balance. [0003] The roots of conventional green grass are shallow, and the water required is mainly obtained through surface irrigation. Under normal maintenance conditions, the typical daily water consumption of turfgrass is 2.5-7.5 mm, and the maximum is 12 mm. Lawn irrigation water has become an important way of water for many urban landscape facilities. Moisture has become the ma...
