High-stability fixing pile
The invention provides a high-stability fixing pile, and belongs to the field of construction supporting member manufacturing. The high-stability fixing pile comprises a sleeve and a screw rod; the sleeve sleeves the screw rod; a screwing device is installed at the top end of the screw rod, and the screw rod abuts against the sleeve through the screwing device; a conical head is installed at the bottom end of the screw rod, and an expansion head is installed at the bottom end of the sleeve; the expansion head sleeves the conical head; and the screwing device rotates to compress the sleeve downwards, and the expansion head sleeves the conical head to expand in the radial direction. According to the high-stability fixing pile, the sleeve is compressed through the screwing device, so that theexpansion head is compressed and expanded, the external diameter of the sleeve is increased, frictional force of the sleeve and external-side pile holes can be improved, the load-carrying property and extraction resistance of the high-stability fixing pile are improved, smaller diameter and length are achieved, and the installation is simple and convenient.
本发明提供一种高稳固性固定桩，属于基建支撑构件制造领域，本发明包括：套管和丝杆；所述丝杆套设在所述套管内；所述丝杆的顶端安装有旋紧装置，所述丝杆通过所述旋紧装置与所述套管相抵靠；所述丝杆的底端安装有锥形头，所述套管的底端安装有膨胀头；所述膨胀头套设在所述锥形头上；所述旋紧装置转动，以向下压紧所述套管，所述膨胀头套设在所述锥形头上，以使所述膨胀头在径向膨胀。本发明通过旋紧装置下压套管，使膨胀头下压膨胀，进而增大了套管的外径，从而能提高套管与外侧桩孔的摩擦力，进而提高了本发明固定桩的承载性能和抗拔性能，且具有较小的直径和长度，安装简便。
