Test anchor rod construction device and anti-floating test method
The invention provides a test anchor rod construction device and an anti-floating test method. The test anchor rod construction device comprises an anchor rod hole formed below earth and stone, a foundation anchor rod located in the anchor rod hole and a lengthened anchor rod arranged on a foundation of the foundation anchor rod in an extending mode. A grouting pipe sleeves the outer side of the lengthened anchor rod, and a sealing piece is arranged between the outer side of the grouting pipe and the anchor rod hole in the position where the foundation anchor rod is located. The foundation anchor rod comprises at least three anchor rod steel bars, fixing pieces located between the anchor rod steel bars and positioning pieces arranged on the outer sides of the anchor rod steel bars. Cement mortar for fixing the foundation anchor rod is poured into the anchor rod hole through the grouting pipe. According to the invention, the anti-floating test can be carried out before earth-rock excavation, and the overall construction period is shortened.
本发明提供一种试验锚杆施工装置及抗浮试验方法，其中的装置包括：设置在土石方下方的锚杆孔、位于锚杆孔内的基础锚杆，以及在基础锚杆的基础上延长设置的加长锚杆；其中，在加长锚杆的外侧套设有注浆管，在注浆管的外侧与基础锚杆所在位置的锚杆孔之间设置有密封件；基础锚杆包括至少三根锚杆钢筋、位于锚杆钢筋之间的固定件以及设置在锚杆钢筋外侧的定位件；通过注浆管在锚杆孔内灌注固定基础锚杆的水泥砂浆。利用上述发明能够在土石方开挖之前进行抗浮试验，缩短整体施工周期。
