Cleaning method of drilling hole of anti-seepage grouting of cultural relic protecting engineering rock mass

The invention discloses a cleaning method of a drilling hole of anti-seepage grouting of cultural relic protecting engineering rock mass. Improvement is carried out on the basis of traditional drilling hole cleaning, through precise positioning of a micro crack, the single crack is precisely cleaned to meet the groutability of crack, and the strength of a stone body is improved; meanwhile, considering that construction is carried out in a cultural relic protecting area, a large quantity of cleaning water can generate negative influence on a cultural relic body and can possibly influence a proportion of a size, so that the cleaning method controls the quantity of the cleaning water, and a water extraction method and secondary compressed air cleaning after cleaning are adopted. 本发明公开了一种文物保护工程岩体防渗灌浆的钻孔清洗方法，在传统的钻孔清洗的基础上给予改良，通过裂隙的精确定位、对单一微裂隙进行精确清洗以满足其可灌性，提高结石体强度。同时，考虑到在文物保护区施工，大量的清洗用水可能对文物本体产生不利影响，并有可能会影响浆液配比，因此本方法对清洗水量进行了控制，并采取了清洗后抽水措施和二次压缩空气清洗。
