Seepage prevention method for sealing large underground cavern by adopting advanced grouting
The invention discloses a seepage prevention method for sealing a large underground cavern by adopting advanced grouting. The seepage prevention method mainly involves a vertical seepage prevention layer, a top seepage prevention layer, a bottom seepage prevention layer and a grouting gallery for constructing the seepage prevention layers. The grouting gallery is constructed in advance before the large underground cavern is excavated, the annular sealed vertical seepage prevention layer is constructed around the underground cavern, the top seepage prevention layer and the bottom seepage prevention layer are constructed at the upper part and the lower part, and the adjacent seepage prevention layers are tightly connected, so that the aims of sealing surrounding rock masses in advance and reducing the water seepage amount of the large underground cavern in a construction period and an operation period are achieved. According to the seepage prevention method, the annular sealed vertical seepage prevention layer is formed on the surrounding rock masses of the large cavern in advance before the large cavern is excavated, and is combined with the top seepage prevention layer and the bottom seepage prevention layer to seal the surrounding rock masses in advance, so that the water seepage of surrounding rocks is reduced, the engineering safety is guaranteed, and the influence on the underground water environment is reduced.
本发明公开了一种大型地下洞室采用超前灌浆封闭的防渗方法，主要包括竖向防渗层、顶部防渗层、底部防渗层和用于施工防渗层的灌浆廊道。通过在大型地下洞室开挖前预先施工灌浆廊道，在地下洞室四周施工环形封闭的竖向防渗层，在上部和下部施工顶部防渗层和底部防渗层，并使相邻防渗层紧密衔接，达到超前封闭周边岩体、减小大型地下洞室施工期和运行期渗水量的目的。本发明通过在大型洞室开挖前，预先在大型洞室周围岩体形成环形封闭的竖向防渗层，并与顶部和底部防渗层结合，超前封闭周边岩体，减少围岩渗水，保障工程安全，降低对地下水环境的影响。
