Slope landslide protection structure for strip mine in quicksand layer
The quicksand layer strip mine slope landslide protection structure comprises a first fiber concrete layer, a drainage ditch, a drainage channel, shallow grouting holes and a second fiber concrete layer, and the first fiber concrete layer is sprayed to the surface of a bottom slope; the drainage ditch is arranged on the slope bottom face and extends in the length direction of the slope. The outer end part of the drainage channel extends out of the surface of the bottom side slope and is communicated with the drainage ditch, and the inner end part of the drainage channel extends into the bottom side slope to be communicated with underground water; cement paste is poured into the shallow grouting holes, and the cement paste can permeate into the bottom side slope to fill quicksand layer pores after underground water is drained; the second fiber concrete layer is sprayed on the surface of the first fiber concrete layer. The whole quicksand layer is prevented from being treated, the engineering amount is greatly reduced, the construction period is greatly shortened, construction is easy, the construction cost is low, economical efficiency is good, underground water erosion is avoided, the sand layer is softened, and the self-stability of the quicksand layer, especially the stability of the upper side slope is improved.
本发明公开了一种流沙层露天矿边坡滑坡防护结构，包括第一纤维混凝土层、排水沟、疏干通道、浅部注浆孔和第二纤维混凝土层，第一纤维混凝土层喷射在底部边坡表面；排水沟设置在坡底面上且沿着边坡长度方向延伸；疏干通道外端部向外伸出底部边坡表面并与排水沟相接通，其内端部向底部边坡内部延伸至与地下水相接通；浅部注浆孔内灌注有水泥浆，且水泥浆可渗透至底部边坡内部以填充疏干地下水后的流沙层孔隙；第二纤维混凝土层喷射在第一纤维混凝土层表面。避免对整个流沙层进行治理，大幅节约了工程量和工期，施工简单，施工费用低，经济性好，也避免地下水侵蚀、软化沙层，提高了流沙层的自稳性，尤其是上部边坡的稳定性。
