Soil anchor rod construction process
The invention discloses a soil anchor rod construction process. The process comprises the following steps that S1, mechanical equipment and materials enter a construction site; S2, an anchor rod bodyis manufactured; S3, anchor hole positioning is conducted; S4, hole drilling and hole cleaning are conducted; S5, the anchor rod body is placed in; S6, primary grouting is conducted; wherein primary perfusion slurry is a microbial liquid, the microbial liquid is composed of bacillus pasteurii S.pateurii and a culture solution, every 1 L of the culture solution contains 5-15 g of a yeast extract, 2-8 g of sodium chloride, 10-30 g of urea, 0.3-0.8 mg of ferric citrate and 0.4-0.7 mg of sodium molybdate, and the pH value of the microbial liquid is adjusted to be 7.5-8; S7, secondary grouting is conducted; and S8, tertiary grouting is conducted. According to the method, the bonding strength between the hole wall (soil body) of a drilled hole and a grouting body can be improved, the anchoring force is high, the damage of the soil anchor rod is effectively avoided, and the construction safety is improved.
本发明公开了一种土层锚杆施工工艺，包括以下步骤：S1、机械设备及其材料进入施工现场；S2、制作锚杆杆体；S3、锚孔定位；S4、钻孔及清孔；S5、置入锚杆杆体；S6、一次注浆；一次灌注浆液为微生物菌液，所述微生物菌液由巴氏芽孢杆菌S.pasteurii及培养液组成，其中，每1L培养液中含有酵母浸膏5‑15g、氯化钠2‑8g、尿素10‑30g、柠檬酸铁0.3‑0.8mg、钼酸钠0.4‑0.7mg，调节微生物菌液的pH值为7.5‑8；S7、二次注浆；S8、三次注浆。该发明可以提升钻孔孔壁(土体)与灌浆体之间的粘结强度，锚固力强，有效避免土层锚杆病害的发生，提高施工的安全性。
