岩石锚杆基础由于其混凝土方量较小,具有显著的经济性,而被国网公司在近年来的特高压直流输电线路工程进行推广。根据目前特高压直流输电线路中锚杆基础施工中存在的锚孔定位有偏差、成孔尺寸控制不严、钻孔方式不当而造成锚孔附近土质扰动、锚孔浇制混凝土强度控制不严等问题,对如何加强锚杆基础施工中监理管控的重点和难点进行分析,并提出相关措施。 Because of its small amount of concrete, rock bolt foundation has obvious economy, and it is popularized by State Grid Corporation in recent years for UHV DC transmission line project. According to the deviation of the anchoring holes existing in the construction of the anchor foundation in the UHVDC transmission line at present, the control of the forming hole size is not strict and the drilling method is not proper, which causes the disturbance of soil quality near the anchoring hole and lax control of the concrete strength of the anchoring hole pouring Problems, analyze how to strengthen the key points and difficulties in the supervision and control of anchor foundation construction, and put forward relevant measures.
