| description | The invention discloses a pretreatment method for landslide dam impervious wall grooving construction. The pretreatment method includes the steps that a row of blast holes are drilled in the axis of alandslide dam impervious wall with the boulder content exceeding 50% at intervals; and after blast hole drilling is completed, boulders in the blast holes are subjected to blasting treatment, the boulders are broken into stones, and grooving construction of the landslide dam impervious wall can be conducted under the block geological conditions. By means of the method, the landslide dam geological conditions that many boulders exist, the particle size is large, the overhead phenomenon is serious, and a stratum is not deposited and cemented can be improved, and impervious wall construction canbe better conducted on the stratum subsequently.
本发明公开了一种堰塞体防渗墙成槽施工的预处理方法，包括：在孤石含量超过50％的堰塞体防渗墙的轴线上，间隔钻设一排爆破孔；爆破孔钻设完成后，对爆破孔内遇到的孤石进行爆破处理，将孤石破碎成块石，以便在块石的地质条件下进行堰塞体防渗墙的成槽施工。本发明的方法，可改善孤石多、粒径大、架空现象严重、地层未经沉积和胶结的堰塞体的地质条件，利于后续在该地层上进行防 |
