Foundation pile group construction method
The invention relates to a foundation pile group construction method. The method comprises the following steps: firstly, a protection pit with the diameter of 1 meter and the depth of 1.5 meters is dug in a building ground, and then a protection sleeve with the outer ring diameter of 1 meter and the height of 1.8 meters is vertically and coaxially inserted into the protection pit; secondly, a foundation pit with the diameter of 0.9 meter and the depth of 15 meters is coaxially drilled in the bottom of the protection pit through drilling equipment, a tamper penetrates into the foundation pit to tamp the bottom of the foundation pit, and the depth of the foundation pit is tamped to be 20 meters; thirdly, a steel cage is tightly attached to the side wall of the foundation pit and placed into the foundation pit, and then the foundation pile is vertically inserted into the steel cage; fourthly, concrete is poured into the foundation pit, and when the concrete is close to the top layer and the protection pit, concrete pouring is stopped; and fifthly, a protection sleeve is vertically and slowly taken out and prepared for next-time use. The method has the advantages of increasing the firmness degree, stability and the like of the formed foundation pile and the like.
本申请涉及一种基础桩群施工方法，包括步骤一，在建筑地面挖取直径1米，深度1.5米的防护坑，然后在防护坑内竖直同轴插入外圈直径为1米且高度在1.8米的防护套；步骤二，通过钻孔设备在防护坑的底部同轴钻出直径为0.9米，深度为15米的基坑，将夯锤深入基坑内对基坑的底部进行夯实，将基坑的深度夯实至20米；步骤三，将钢笼贴紧基坑侧壁放入基坑内，再将基桩竖直插入钢笼内；步骤四，向基坑内灌注混凝土，当混凝土接近顶层接近防护坑时停止；步骤五，将防护套竖直缓慢取出，准备下一次使用。本申请具有提高成型后基桩的牢固程度和稳定性等特点。
