Ultrahigh-pressure jet grouting pile auxiliary anti-seepage method for anti-seepage wall of earth and rockfill dam with deep covering layer
The invention discloses a deep covering layer high earth and rockfill dam anti-seepage wall ultrahigh pressure jet grouting pile auxiliary anti-seepage method, and belongs to the technical field of building construction. The method comprises the steps of foreground arrangement, background arrangement and waste slurry sedimentation tank arrangement; determining the reinforcing position of the concrete diaphragm wall, measuring and setting out the reinforcing position, and numbering; guide hole construction; an ultrahigh-pressure jet grouting pile main machine is adopted for conducting ultrahigh-pressure jet grouting on formed holes, and reinforcing is conducted to form a single pile; and the ultrahigh-pressure jet grouting pile main machine is moved to the next pile position, and according to the reinforcing requirement of the anti-seepage wall of the earth and rockfill dam with the deep covering layer height, reinforcing of all the engaged row piles is completed. By arranging the ultrahigh-pressure jet grouting occlusion row piles, the strength of upstream and downstream covering layer soil bodies is enhanced, a more stable anti-seepage system is formed, and the stress of the concrete anti-seepage wall is reduced; and meanwhile, the ultrahigh-pressure jet grouting secant piles are anti-seepage bodies and can assist in seepage prevention, and the anti-seepage effect of the earth and rockfill dam with the deep covering layer height is improved.
本发明公开了一种深厚覆盖层高土石坝防渗墙超高压旋喷桩辅助防渗方法，属于建筑施工的技术领域，其包括进行前台布置、后台布置和废浆沉淀池的布置；确定混凝土防渗墙加固位置，对加固位置进行测量放线，并进行编号；引孔施工；采用超高压旋喷桩主机对成孔进行超高压旋喷注浆，并加固成单桩；将超高压旋喷桩主机移动至下一个桩位，根据深厚覆盖层高土石坝防渗墙加固需求，直至完成全部咬合排桩加固。本发明通过设置超高压旋喷咬合排桩增强上、下游覆盖层土体的强度，形成更稳固的防渗系统，减小混凝土防渗墙应力；同时超高压旋喷咬合桩本身就是防渗体，可辅助防渗，提高深厚覆盖层高土石坝防渗效果。
