Construction process for reshaping and seepage prevention of garbage mountain body
The invention discloses application of a construction process for reshaping and seepage prevention in seepage prevention and collapse prevention of a garbage mountain body. The construction process comprises the following steps that firstly, a seepage-proof wall and a concrete cover plate are poured, and curtain grouting is conducted after the seepage-proof wall and the concrete cover plate reach certain strength; curtain grouting is conducted after consolidation grouting is completed and inspection and acceptance are qualified; and the curtain grouting process comprises the steps of covering layer cleaning, hole site lofting, grouting pipe pre-burying, concrete cover plate pouring, curtain grouting drilling, hole wall washing, hole opening blocking, crack washing, water pressing experiment, grouting, hole sealing and quality inspection. An auxiliary cast-in-place concrete cover plate is arranged, the grouting condition can be improved, the grouting effect can be improved, the qualified rate of the hole position, the hole depth and the hole inclination of a drilled hole reaches 99.5% or above, the production efficiency is improved, and the construction quality is effectively improved; and hole wall washing and crack washing are conducted in a large-flow pressure water pulsation mode, double-row hole grouting is adopted, the construction efficiency is greatly improved, the actual construction period is shortened by 12 days, the labor cost is saved by 360,000 yuan, and direct economic benefits are remarkable.
一种山体整形防渗的施工工艺在垃圾山体防渗、防塌陷中的应用，包括以下步骤：先进行防渗墙、砼盖板的浇筑，待防渗墙、砼盖板达到一定强度后进行帷幕灌浆；在固结灌浆完毕并检查验收合格后进行帷幕灌浆；帷幕灌浆工序包括：覆盖层清理→孔位放样→预埋灌浆管→砼盖板浇筑→帷幕灌浆钻孔→孔壁冲洗→孔口阻塞→裂隙冲洗→压水实验→灌浆→封孔→质量检查；本发明设置辅助现浇砼盖板，可改善灌浆条件，提高灌浆效果，钻孔的孔位、孔深、孔斜度合格率达到99.5%以上，提高生产效率，有效提高施工质量；采用大流量压力水脉动方式进行孔壁冲洗与裂隙冲洗，采用双排孔灌浆，施工效率大幅提升，实际缩短工期12天，节省人工费成本36万元，直接经济效益显著。
