Abstract

The invention discloses an overflowing-pipe-containing saline-alkali region water resource collecting and utilizing system, which comprises a soil body and storage and drainage wells. The soil body comprises a planting soil layer, a permeable membrane layer, a water storage layer, waterproof layers and a saline-alkali soil layer which are sequentially arranged from top to bottom; a trench protruding into the saline-alkali soil layer is formed in the lower surface of the water storage layer and internally provided with a concealed conduit; the concealed conduit is connected and communicates with the storage and drainage wells in the slope direction; the storage and drainage wells are formed in the soil body at intervals, the depths of the storage and drainage wells extend to the lower partof the trench from top to bottom, well walls of the parts, making contact with the water storage layer, of the storage and drainage wells are each of a permeable pipe structure, and well walls of other parts are each of an impermeable structure; overflowing drainage pipes are arranged on the walls of the storage and drainage wells, and the horizontal height of the overflowing drainage pipes is atthe depth of 20-50 cm of the planting soil layer; and junctions of the system and surrounding buildings or structures are inversely packed through the lateral waterproof layers. Rainwater permeating into the planting soil layer after precipitation can be effectively collected, and salt return of the saline-alkali soil layer to the planting soil layer is avoided.

Description

Technical field

[0001] The invention belongs to the field of saline-alkali water treatment, and particularly relates to a saline-alkali water collection and utilization system containing an overflow pipe. Background technique

[0002] Rainwater is a very precious freshwater resource, especially for coastal saline-alkali land. In such severely water-deficient areas, collecting and using rainwater is even more precious. Due to lack of water in saline-alkali land, the salt concentration in the soil exceeds the plant's ability to withstand it, causing salt damage. Salt comes with water, and salt goes with water, so an adequate supply of fresh water resources must be ensured so that saline-alkali land resources can be used sustainably.

[0003] The total area of ​​coastal saline-alkali soil in my country reaches 500×10 4 hm 2 ,. In recent years, with the development of economy and industry, saline-alkali areas have become a new position for economic development. In order to meet the n...
