地浸钻孔水泥封孔技术决定着钻孔使用的可靠程度和服务年限。传统的封孔方法是产生混浆段的根源 ,因此 ,提出一种非传统的逆向灌注方法 ,并研制其灌注器具势在必行 ,在此基础上 ,配套合理的施工工艺 ,力求取得预期效果。
Ground impregnation drilling cement sealing technology determines the reliability of drilling and service life. The traditional sealing method is the root of mixing segment. Therefore, it is imperative to propose a non-traditional reverse perfusion method and develop its perfusion device. On the basis of this, a reasonable construction technology is required to achieve the desired effect .
