Ecological anti-seepage structure for waste rock heap in waste pyrite area and construction method of ecological anti-seepage structure
The invention relates to the technical field of waste pyrite area treatment, in particular to a waste pyrite area waste rock heap ecological anti-seepage structure and a construction method thereof. Comprising a passivation layer formed on the surface layer of a waste rock heap in a waste pyrite area, a net-hanging and concrete-spraying layer arranged on the surface of the passivation layer, a lattice beam arranged on the surface of the net-hanging and concrete-spraying layer and an earthing greening layer arranged in a grating space of the lattice beam. A net fixing anchor rod pipe and a slope fixing anchor rod pipe are arranged in the waste rock pile, the steel wire net of the net hanging and concrete spraying layer is fixed to the waste rock pile side slope through the net fixing anchor rod pipe and the slope fixing anchor rod pipe, and the lattice beam is fixed to the waste rock pile side slope through the slope fixing anchor rod pipe. According to the method, in-situ sealing is carried out on the waste rock heap in the waste pyrite area through the passivation layer, the net hanging and concrete spraying layer, the slope fixing anchor rod pipes and the lattice beams, pyrite acid waste water can be greatly reduced from the source, the overall structure has long-term stability and function durability, and meanwhile ecological reconstruction can be well achieved through the soil covering greening layer.
本发明涉及废弃硫铁矿区治理技术领域，具体涉及一种废弃硫铁矿区废石堆生态防渗结构及其施工方法，包括形成于废弃硫铁矿区废石堆体表层的钝化层、设置于钝化层表面的挂网喷混凝土层、设置于挂网喷混凝土层表面的格构梁以及设置于格构梁的格栅空间中的覆土绿化层；废石堆中设置有固网锚杆管和固坡锚杆管，挂网喷混凝土层的钢丝网通过固网锚杆管和固坡锚杆管固定于废石堆边坡上，格构梁通过固坡锚杆管固定于废石堆边坡上。本发明通过钝化层、挂网喷混凝土层、固坡锚杆管和格构梁对废弃硫铁矿区废石堆体进行原位封存，可以从源头上大幅度减少硫铁矿酸性废水，且整体结构具备长期稳定性和功能长久性，同时利用覆土绿化层可以较好地实现生态重构。
