摘要
目前桩基础施工中存在的诸如混凝土离析、断桩等严重桩身缺陷,采用一般的注浆方法很难保证断面补强的可靠性。针对这一情况,结合某桥桩基处理施工经验,介绍了高压旋喷帷幕注浆的新方法,以供桩基缺陷处理中参考应用。
Targeting at severe pipe defects such as concrete disintegration, rupture, etc. existed in current pile foundation construction, common grouting method is diifficult to assure the reliability of reinforcement of the rupture face, for this situation, a construction experience with integration of bridge pier treatment experience is put forward, and a new method for high pressure screw spray curtain grouting is introduced for reference in pile defect treatment.
