Construction method of full-bonding support anchor rod
The invention relates to the technical field of building construction, and discloses a construction method of a full-bonding support anchor rod. The construction method of the full-bonding support anchor rod comprises the following operation steps of 1, leveling a site; 2, manufacturing the anchor rod; 3, positioning the position of the anchor rod; 4, preparing a drilling machine; 5, digging a mudpit; 6, enabling the drilling machine to be in place; 7, drilling by the drilling machine; 8, mounting the anchor rod; 9, carrying out hole opening slurry supplementing and secondary grouting; and 10, carrying out tensioning. According to the construction method of the full-bonding support anchor rod, in the support anchor rod construction under the unfavorable geology of silty clay and the like,the phenomena of hole collapse and necking in the anchor rod hole forming process can be effectively avoided, and it is guaranteed that the diameter of an anchor hole meets the design requirement; and the plumpness of cement paste in an anchor rod formed hole is completely guaranteed through the mud replacement technology and the secondary grouting technology, the full length of the support anchor rod is fully bonded with cement mortar, it is guaranteed that an anchor rod body makes full contact with a soil body, the bonding friction resistance between the anchor rod body and the soil body isenhanced, and therefore the foundation pit supporting strength is guaranteed.
本发明涉及建筑施工技术领域，且公开了一种全粘结支护锚杆施工方法，所述全粘结支护锚杆施工包括以下操作步骤：一、场地平整；二、锚杆制作；三．锚杆位置定位；四、钻机设备；五、挖泥浆池；六、钻机就位；七、钻机钻进；八、锚杆安装；九、孔口补浆及二次注浆；十、张拉。该全粘结支护锚杆施工方法，在粉质黏土等不良地质下的支护锚杆施工，本方法能有效避免锚杆成孔过程中塌孔、缩颈现象的发生，保证锚孔的直径满足设计要求；利用泥浆置换、二次注浆工艺，完全保证锚杆成孔内水泥浆的饱满度，使得支护锚杆全长与水泥砂浆充分粘结，保证锚杆体与土体充分接触，增强锚杆体与土体的粘结摩擦阻力，从而保证基坑支护的强度。
