System and method for highly-efficient improvement of coastal viscous heavy saline soil through rainwater
The invention discloses a system and method for highly-efficient improvement of coastal viscous heavy saline soil through rainwater. The system comprises a soil body, a water storage well and an intelligent control system, wherein the soil body comprises to-be-improved viscous heavy saline-alkali soil, a water permeable membrane layer, a water storage layer, a waterproof layer and a saline-alkalisoil layer which are sequentially arranged from top to bottom; a water taking pit is arranged at the bottom of the water storage well; a water taking pipe is arranged in the water storage well; the water inlet of the water taking pipe is provided with a water suction pump and extends into the water taking pit; the outlet end of the water taking pipe is horizontally arranged below the surface of the to-be-improved viscous heavy saline-alkali soil; one end of the outlet end of the water taking pipe is provided with a sprinkling irrigation device extending upwards out of the to-be-improved viscous heavy saline-alkali soil; the other end of the water taking pipe is connected with a flow abandoning device. The system and method provided by the invention have the following advantages: saline soil can be circularly leached with water permeating into the water storage well; operation is simple and convenient; automatic control is achieved; cyclic utilization of water resources is achieved; rainfall can be efficiently utilized to leach the saline-alkali soil; the effect of improving the saline-alkali soil in one rainy season is achieved; the construction period is shortened through the rainy season; fresh water resources are saved; and the improvement cost is low.
本发明公开了一种雨水高效改良滨海黏重盐渍土的系统和方法，系统包括土壤本体、蓄水井和智能控制系统；所述土壤本体包括从上到下依次设置的待改良重黏盐碱土、透水膜层、蓄水层、防水层、盐碱土层；所述蓄水井的井底设有取水窝，蓄水井内设有取水管，该取水管进水口设有抽水泵并一直延伸到取水窝内，取水管出口端水平设置在待改良黏重盐碱土表面下方，所述取水管出口端一头设有向上伸出待改良黏重盐碱土的喷灌装置，一头连接弃流装置。本发明系统和方法可将渗透进入蓄水井的水循环淋洗盐渍土，操作简便，自动控制，实现了水资源的循环利用，可高效利用降雨对盐碱土淋洗，实现一个雨季完成盐碱土改良的效果，利用雨期节约工期，节约了淡水资源，改良成本较低。
