Deep thick hard rock underground continuous wall grooving construction method and structure
The invention relates to the technical field of underground continuous wall grooving, in particular to a deep thick hard rock underground continuous wall grooving construction method. The method comprises the following steps of first, measuring, positioning and constructing a guide wall; second, performing wall protection on a soil layer at the upper part by adopting a wall protective sleeve first, then drilling into the wall protective sleeve by adopting a down-the-hole hammer, drilling into a rock layer to a designed elevation, repeating the steps above, and drilling a plurality of first guide holes which are arranged adjacently; third, drilling a second guide hole between adjacent two first guide holes by adopting a down-the-hole hammer with pipe drilling method, and communicating the second guide hole with the adjacent two first guide holes to form a groove; fourth, trimming the groove and cleaning the groove by adopting a hydraulic grabbing bucket; fifth, mounting reinforcing meshpieces and grouting a guide pipe; and sixth, grouting concrete. The construction method disclosed by the invention is high in hole guiding speed; moreover, a hole is not required to be trimmed by adopting an impact plane set-hammer after the hole is guided; processes are reduced; and the construction efficiency is higher.
本发明涉及地下连续墙成槽及时领域，具体涉及深厚硬岩地下连续墙成槽施工方法，包括步骤一、测量定位、修筑导墙；步骤二、先采用护壁套管对上部土层进行护壁，然后采用潜孔锤钻进护壁套管内并向岩层钻进至设计标高，重复上述步骤，钻多个相邻布置的一序引孔；步骤三、采用潜孔锤跟管钻进法在相邻两个一序引孔之间钻二序引孔，所述二序引孔与相邻两个一序引孔连通成槽；步骤四、采用液压抓斗修槽、清槽；步骤五、安装钢筋网片和灌注导管；步骤六、灌注混凝土。本发明的施工方法引孔速度快，且引孔后无需再采用冲击方锤修孔，减少了工序，施工效率更高。
