Seasonally frozen soil area spiral steel pile forming mode
The invention discloses a spiral steel pile forming mode in a seasonal frozen soil region, and mainly relates to the technical field of foundation piles. Comprising the following steps: S1, surveying and setting out according to a confirmed total construction plan; s2, each position where piling is needed is determined; s3, the long spiral pile drilling machine is moved to the position where piling is needed; s4, the bottom end of the long twist drill is drilled to the position below the frozen soil layer; s5, cleaning sediments and other covering soil in the holes; s6, the bottom end of the spiral steel pile is drilled and pressed into the non-frozen soil layer; s7, concrete is poured into a hole in the outer side of the spiral steel pile through a chute until the height of the surface layer is reached; s8, the concrete in the hole is subjected to vibration treatment; s9, the concrete subjected to vibration treatment is subjected to curing treatment; the occlusion force between the spiral blade and the concrete and the friction force between the spiral steel pile and the concrete are increased, the pulling resistance and the pressure resistance of the spiral steel pile are greatly improved, and the pulling resistance of the spiral steel pile in the frozen soil region in the year-round season can be met.
本发明公开了一种季节冻土区螺旋钢桩成桩方式，主要涉及基础桩技术领域；包括步骤：S1、根据确认的施工总平面图进行测量放线；S2、定出每个需要打桩的位置；S3、将长螺旋钻桩机移动至需要打桩的位置；S4、将长螺旋钻的底端钻至冻土层以下；S5、清理孔内沉渣及其他覆土；S6、将螺旋钢桩的底端钻压至非冻土层中；S7、通过溜槽将混凝土灌入螺旋钢桩外侧的孔内直至地表层高度；S8、对孔内的混凝土进行振捣处理；S9、对经过振捣处理的混凝土进行养护处理；本发明增大了螺旋叶片与混凝土之间咬合力和螺旋钢桩本身与混凝土的摩擦力，极大提高了螺旋钢桩的抗拔、抗压能力，能够满足长年季节冻土区螺旋钢桩的抗拔能力。
