Novel steel anchor pile
The invention belongs to the technical field of civil engineering, and particularly relates to a novel steel anchor pile which is composed of a bottom plate, stiffening ribs, a steel pipe pile, triangular conical rib plates and a pile tip. The bottom plate is welded at the top end of the steel pipe pile, the stiffening ribs are welded on the bottom surface of the bottom plate and the outer surface of the steel pipe pile, the triangular conical rib plates are divided into a plurality of groups, the number of the triangular conical rib plates in each group is four, the triangular conical rib plates are circumferentially and uniformly welded on the steel pipe pile, and the pile tip is welded at the bottom of the steel pipe pile. The side resistance of the pile body below the standard freezing depth is increased due to the fact that soil around the pile is compacted, meanwhile, due to the existence of the conical rib plates, the effective soil body radius for resisting frost heaving force within the pile body range is increased, the side resistance of the pile body and the self weight of the soil body within the effective soil body radius around the pile jointly resist tangential stress generated by soil body frost heaving, and therefore the anchoring force of the pile body is improved; the problem of pile foundation freezing pulling in the frozen soil area is effectively solved.
本发明属于土木工程技术领域，具体涉及一种新型的钢锚桩，所述钢桩基础由底板、加劲肋、钢管桩、三角锥形肋板和桩尖组成；所述底板焊接在钢管桩的顶端，所述加劲肋焊接在底板的底面和钢管桩的外表面上，所述三角锥形肋板分为多组，每组中三角锥形肋板的数量为4个，且圆周均布地焊接在钢管桩上，所述桩尖焊接在钢管桩的底部。标准冻深以下桩体由于桩周土被挤密，增加其侧阻力，同时锥形肋板的存在，使桩身范围内抵抗冻胀力的有效土体半径增加，桩身侧阻力及桩周有效土体半径内土体自重共同抵抗土体冻胀产生的切向应力从而提高桩体的锚固力，有效解决了冻土地区桩基冻拔的问题。
