Method for reinforcing foundation under existing viaduct
The invention discloses a method for reinforcing a foundation under an existing viaduct. The method comprises cement mixing piles, pile caps and a graded gravel cushion, wherein the cement mixing piles are divided into an end cement mixing pile and a middle cement mixing pile, the end cement mixing pile is in a vertical state, the middle cement mixing pile is in an inclined state, and the cement mixing piles are in lap joint with one another to form a net-shaped whole; the pile caps are used for enhancing the connecting effect of the pile tops of the stirring piles and can be made of cement mortar or other materials with good gelling and stress effects; and the gravel cushion is graded gravel. According to the method, construction is convenient, the cost is low, the treatment effect is good, and the foundation treatment problem under the condition that the clear height is limited is solved.
本发明公开了一种既有高架桥下地基加固方法，包括水泥搅拌桩、桩帽、级配碎石垫层。所述的水泥搅拌桩分为端部水泥搅拌桩和中间水泥搅拌桩，端部水泥搅拌桩为垂直状态，中间水泥搅拌桩为倾斜状态，水泥搅拌桩相互搭接，形成一个网状整体；所述的桩帽用于加强搅拌桩桩顶的连接效果，可以为水泥砂浆或其他具有较好胶凝和受力效果的材料；所述的碎石垫层为级配碎石，本发明施工方便、成本低廉、处理效果好，解决了净高受限条件下的地基处理难题。
