Construction method of large-diameter socketed pile for complex rock stratum
The invention discloses a construction method of a large-diameter socketed pile for a complex rock stratum, which comprises the following steps of: providing a rotary drilling rig, a hydraulic vibration hammer and a steel sleeve, performing hole guiding on a pile hole design position by utilizing the rotary drilling rig, and inserting the steel sleeve into the hole guiding position by utilizing the hydraulic vibration hammer; providing two laser gradienters, arranging the two laser gradienters into 90 degrees by taking the steel sleeve as a base point, respectively projecting plumb lines to two edges of the steel sleeve, observing whether the two plumb lines are completely projected to correspond to the edges or not, and performing perpendicularity adjustment on the projections not at the corresponding edges, pressing the steel sleeve by using the hydraulic vibrating hammer, and repeating the detection steps until the steel sleeve is pressed in place; drilling and soil taking are conducted on the interior of the steel sleeve through the rotary drilling rig; lowering a reinforcement cage into the steel sleeve and pouring to form a pile; and pulling out the steel sleeve. Through the construction method, the construction quality is ensured.
本发明公开了一种用于复杂岩层的大直径嵌岩桩的施工方法，包括步骤：提供旋挖钻机、液压振动锤以及钢套管，利用所述旋挖钻机对桩孔设计位置进行引孔，利用所述液压振动锤将所述钢套管插设在引孔位置处；提供两个激光水平仪，将两个所述激光水平仪以所述钢套管为基点布置成90°、并分别向所述钢套管的两个边缘处投射铅锤线并观察两个所述铅垂线是否均完全投影对应所述边缘处，投影不在对应边缘处进行垂直度调整，利用所述液压振动锤打压所述钢套管，并重复上述检测步骤直到所述钢套管打压到位；利用所述旋挖钻机对所述钢套管内进行钻孔取土；下放钢筋笼至所述钢套管内并浇筑成桩；拔出所述钢套管，通过上述施工方法保证了施工质量。
