Construction method of non-weathered hard rock pile foundation anchor cable
The invention relates to the field of construction engineering construction method, in particular to a construction method of a non-weathered hard rock pile foundation anchor cable. According to the construction method, the construction efficiency is improved, the construction period is shortened, and the construction cost is lowered. The construction method comprises the following steps that (1)determination of anchor hole drilling time is conducted, specifically, the anchor hole drilling time is the seventh day of pile foundation concrete curing; (2) site arrangement is conducted, and a working platform is erected; (3) a foundation is retest; (4) a drilling rig is installed; (5) hole forming is conducted; (6) an anchor cable is prepared and installed; (7) grouting of an anchorage section is conducted; (8) the uplift test of the anchor cable is conducted; and (9) sealing and grouting of a free section are conducted. The construction method has the beneficial effects that the processtechnical problems of prone deviation of a drilling hole, large vertical deviation, serious ash cleaning pollution, incomplete ash cleaning of hole depth, poor elasticity of a too long grouting pipe,prone deformation of anchor cable lifting, difficult pipe withdrawal of the grouting pipe in the construction can be effectively solved, the method is adopted for construction, the construction efficiency can be effectively improved, the construction period is shortened, the construction cost is lowered, and the project quality is effectively controlled.
本发明涉及建筑工程施工方法领域，尤其是一种提高施工效率、缩短工期、降低施工成本的非风化坚硬岩石桩基锚索施工方法，包括如下步骤：(1)锚孔钻孔时间的确定：锚孔钻孔时间为桩基混凝土养护第7天；(2)场地整理、搭设工作平台；(3)基础复测；(4)安装钻机；(5)成孔：(6)制安锚索，(7)锚固段注浆；(8)锚索抗拔试验；(9)自由段封孔压浆。本发明的有益效果是：本发明可以有效解决钻孔易出现偏孔、垂直度偏差大、清灰污染严重、孔深清灰不彻底、注浆管太长弹性差、锚索吊放易变形、注浆管退管困难等施工中的工艺技术难题，采用本方法施工，可有效提高施工效率、缩短工期、降低施工成本，实现工程质量有效控制。
