Reinforcing method for dynamic compaction gravel compaction pile in high fill area
The invention provides a reinforcing method for a dynamic compaction gravel compaction pile in a high fill area. The reinforcing method comprises the steps that firstly, holes are drilled in the center and the periphery of the dynamic compaction gravel compaction pile; secondly, a grouting pipe is placed in a center hole of the dynamic compaction gravel compaction pile; thirdly, the slurry return pipe is placed in a peripheral hole of the dynamic compaction gravel compaction pile; 4, grouting is conducted from the bottom of the center hole obtained in the step 1, cement paste is injected from a grouting pipe, and after grout flows out of a grout return pipe, the grouting pipe and the grout return pipe are lifted upwards at the same time; according to the method, drilling circulation high-pressure grouting is conducted on the dynamic compaction gravel compaction pile, gaps of the dynamic compaction gravel compaction pile are filled, the dynamic compaction gravel compaction pile is bonded, the purpose of enhancing the strength and integrity of a pile body of the dynamic compaction gravel compaction pile is achieved, the bearing capacity of the pile body of the dynamic compaction gravel compaction pile is greatly improved, and the construction period is shortened. And the problems of insufficient bearing capacity and overlarge deformation after the construction of the dynamic compaction gravel compaction pile is completed are solved.
本发明提供一种高填方区强夯碎石挤密桩的加固方法，包括步骤一：在强夯碎石挤密桩的中心及四周钻孔；步骤二：把注浆管放入强夯碎石挤密桩的中心孔内；步骤三：把回浆管放入强夯碎石挤密桩的周边孔内；步骤四：注浆从步骤一所得到的中心孔孔底开始，把水泥浆从注浆管注入，待回浆管有浆液流出后，再把注浆管及回浆管同时向上提升；本发明通过对强夯碎石挤密桩采取钻孔循环高压注浆，实现通过对强夯碎石挤密桩的空隙进行充填及对强夯碎石挤密桩的粘结作用，达到增强强夯碎石挤密桩桩身强度及整体性的目的，使强夯碎石挤密桩的桩身承载力大大提高，解决了强夯碎石挤密桩施工完成后承载力不足及变形过大问题。
