Municipal soft foundation road reinforcing method
The invention relates to the technical field of soft foundation road reinforcement, in particular to a municipal soft foundation road reinforcing method. The method comprises the steps that a field isleveled, and pile positions are determined; each pile position is downwardly drilled by one unit depth by taking the ground as a reference surface, and a soil body is removed to form a pile hole; thelower part of the hole wall of each pile hole is extruded and expanded in the circumferential direction to form a branch cavity; pile casings are lowered into the pile holes, the bottom ends of the pile casings abut against the bottom faces of the pile holes, grouting is conducted in gaps between the pile casings and the hole walls of the pile holes till gaps between the branch cavities and the pile holes and the gaps between the pile casings and the hole walls of the pile holes are filled with grout, and branch piles are formed after the grout is solidified; drilling is further performed bytaking the bottom surfaces of the pile holes as a reference surface, and the aforesaid steps are repeated until the pile holes are machined to a required depth; and grout is poured into all sections of the pile casings and the grout is solidified, where in the vertical direction, the outer diameter of a pile casing on a lower layer is smaller than or equal to the inner diameter of a pile casing onan upper layer, and the heights of all sections of the pile casings are equal. The reinforcing method has the effect that the branch pile forming quality is high.
本申请涉及一种市政软基道路加固方法，涉及软基道路加固的技术领域，其包括：平整场地，确定桩位；在各桩位点，以地面为基准面向下钻取一个单位深度并清出土体，形成桩孔；在桩孔孔壁的下部沿周向挤扩形成支盘腔体；向桩孔内下放护筒，使护筒的底端与孔的底面抵紧，并向护筒与桩孔孔壁之间的空隙内注浆，直到浆液充满支盘腔体以及护筒和桩孔孔壁之间的空隙，等待浆液凝固，形成支盘桩；以上述桩孔的底面为基准面继续钻孔，并重复上述步骤，直至加工至所需深度；以及向各段护筒内灌注浆液，等待浆液凝固；其中，在竖直方向上，下一层护筒的外径小于等于上一层护筒的内径，且各段护筒的高度相等。本申请具有支盘桩成桩质量高的效果。
