Prestressed anchor rod pile for reinforcing foundation through jet grouting pile, powder spraying pile or stirring pile and construction method
The invention discloses a prestressed anchor rod pile for reinforcing a foundation through a jet grouting pile, powder spraying pile or stirring pile. The prestressed anchor rod pile is characterizedby involving a soft soil layer foundation comprising, but not being limited to soil layers such as sludge, mucky soil, flow plastic, soft plastic or plastic cohesive soil, plain fill, silt, sandy soil, biological soil and gravel soil, which is improved through the jet grouting pile, powder spraying pile or stirring pile, and a construction hole or directly drilled hole formed in a pile core of thejet grouting pile, powder spraying pile or stirring pile or in a lap joint position of the piles, wherein a composite anchor rod pile or pressure-bearing pile with steel bar main steel bars and a steel bar cage as a framework and cement mortar or poured concrete as a pile body is arranged in the hole, main steel bars of the steel bar cage framework and the anchor rod pile body are pre-tensioned or post-tensioned prestressed steel bars.
一种通过旋喷、粉喷或搅拌桩增强地基基础的预应力锚杆桩，包括通过旋喷粉喷桩、粉喷或搅拌桩，改良软弱土层基础包括但不限于淤泥、淤泥质土、流塑、软塑或可塑粘性土、素填土、粉土、砂土、生物土、碎石土等土层，在旋喷粉喷桩或搅拌桩的桩芯或桩的搭接处设置的施工孔或直接钻孔，孔内设有钢筋主钢筋、钢筋笼为骨架的注水泥砂浆或灌注混凝土为桩体的复合锚杆桩或承压桩；钢筋笼骨架和锚杆桩桩体的主钢筋是先张或后张预应力的钢筋。
