Structure and method for synergistically participating in ecological restoration of waste site by coal-based solid waste
The invention discloses a coal-based solid waste cooperative participation abandoned site ecological restoration structure which comprises a pit type and a channel type, and a restoration method comprises the steps that planting soil, anti-seepage engineering soil and filling engineering soil are artificially prepared; filling and rolling low-permeability anti-seepage engineering soil at the bottom of the site layer by layer to form an external anti-seepage layer; constructing a core layer; low-permeability anti-seepage engineering soil is used for layered filling and rolling to form a rainwater collection and storage system; constructing a soil layer; an environment monitoring facility is constructed, a leachate collecting pool is arranged, and a water guide layer is laid on the upper portion of an impermeable layer of the channel site through gravel-cobble; the method comprises the following steps of: constructing a protective surface measure, constructing a settlement allowance measure, estimating the future maximum settlement at the position with the maximum filling thickness in the middle of the abandoned site, considering the filling height in advance, and ensuring the microtopography requirement of discharging from the top surface to the two sides; the engineering performance requirement and the environmental protection requirement are met, waste is changed into available artificial planting soil, and material source support is provided for synergistic remediation; and sustainable ecological restoration of the waste site is ensured.
本发明公开一种煤基固废协同参与废弃场地生态修复结构，包括矿坑类及沟道类，修复方法包括人工制备种植土、防渗工程土和填筑工程土；在场地底部采用低渗透性防渗工程土分层填筑碾压，形成外部防渗层；构造芯层；使用低渗透性防渗工程土分层填筑碾压，形成雨水收集及储存系统；构造土壤层；构造环境监测设施，设置淋滤液收集池，沟道类场地在防渗层上部使用卵砾石敷设导水层；构造护面措施，构造沉降余量措施，在废弃场地中部填筑厚度最大位置，估算未来最大沉降量，在填筑高度上提前考虑，保证顶面往两侧排泄的微地形要求；实现工程性能要求和环保要求，变废为可用人造种植土，为协同修复提供物源支持；保证了废弃场地的可持续生态修复。
