Sponge city saline-alkali soil alkali discharge system
The invention relates to a sponge city saline-alkali soil alkali discharge system. The sponge city saline-alkali soil alkali discharge system comprises a foundation, a blind pipe ditch, lower inverted filter layers, an alkali discharge blind pipe, a medium sand layer, an isolation layer, an upper inverted filter layer and a planting soil layer; the blind pipe ditch is of a long-strip-shaped structure and is excavated on the foundation; the lower inverted filter layers are laid on the upper surface of the foundation, and the bottom face and the slope face of the blind pipe ditch; a plurality of alkali discharge holes which are distributed in a dispersed manner are formed in the pipe wall of the alkali discharge blind pipe; and the pipe wall of the alkali discharge blind pipe is wrapped with an outer covering inverted filter layer; the alkali discharge blind pipe is laid in the blind pipe ditch in the length direction of the blind pipe ditch, and the middle sand layer is filled around the alkali discharge blind pipe in the blind pipe ditch; the isolation layer is graded broken stone laid on the lower inverted filter layer and the medium sand layer; the upper inverted filter layer is laid on the isolation layer; and the planting soil layer is laid on the upper inverted filter layer. According to the alkali discharge system, salt in soil can be drained away along with water, the underground water level is controlled to be below the critical depth, and the purposes of soil desalination and salinization prevention are achieved.
本发明涉及一种海绵城市盐碱地排碱系统，包括：地基、盲管沟、下层反滤层、排碱盲管、中砂层、隔离层、上层反滤层和种植土层，所述盲管沟为长条状结构，其开挖在地基上，地基上表面、盲管沟的底面和坡面上均铺设有下层反滤层。排碱盲管的管壁上开设有若干分散分布的排碱孔，排碱盲管的管壁上包裹有外包反滤层；排碱盲管沿着盲管沟的长度方向铺设在盲管沟中，中砂层填充在盲管沟中排碱盲管的周围。隔离层为铺设在下层反滤层和中砂层上的级配碎石，上层反滤层铺设在隔离层上，种植土层铺设在上层反滤层上。本发明的这排碱系统不仅能够将土壤中的盐分随水排走，并将地下水位控制在临界深度以下，达到土壤脱盐和防止生盐渍化的目的。
