Construction method of roadbed gravel pile
The invention discloses a roadbed gravel pile construction method, and belongs to the technical field of foundation reinforcement engineering, the roadbed gravel pile construction method comprises the following steps: 1, original ground leveling treatment, 2, construction paying-off, 3, after mechanical equipment enters a site, pile foundation positioning after maintenance is completed, 4, pipe sinking is vibrated to a designed depth, and 5, pipe sinking is completed. The construction method comprises the following steps of (1) feeding, (2) pipe drawing, (3) reverse insertion, (4) pipe drawing, (5) feeding, (6) vibration pipe drawing and reverse insertion, (7) stone supplementary filling construction till top loading, (8) pile forming, repeating the step (3) and continuous construction, and (9) quality detection. According to the construction method of the roadbed gravel pile, the pile is formed through the pipe sinking method according to the technological parameters, the pipe drawing height, the vibration density current, the vibration remaining time, the reverse insertion frequency and depth, the gravel filling amount, the filling rate, the whole process construction time and the like of the roadbed gravel pile, the structural strength of the formed pile is guaranteed, the construction precision is guaranteed to the maximum degree, the bearing capacity of a composite foundation is not smaller than 170 kPa, and the construction period is shortened. And the problem of sedimentation is not easy to generate.
本发明公开了一种路基碎石桩的施工方法，属于地基加固工程技术领域，该路基碎石桩的施工方法，包括以下步骤：步骤一、原地面平整处理，步骤二、施工放线，步骤三、机械设备进场后，检修完成对桩基定位，步骤四、振动沉管至设计深度，步骤五、加料，步骤六、振动拔管、反插，步骤七、补灌石料施工至装顶，步骤八、成桩，重复步骤三，进行持续施工，步骤九、质量检测。该路基碎石桩的施工方法，参照其工艺参数，拔管高度、振密电流、留振时间、反插次数及深度、填碎石量、充盈率、全过程施工时间等，采用沉管法工艺成桩，保证了其成桩的结构强度，最大程度保证施工精度，复合地基的承载力不小于170kPa，不易产生沉降的问题。
