Short spiral soil-squeezing cast-in-place pile construction technology
The invention relates to the technical field of double-spiral soil-squeezing cast-in-place piles, in particular to a short-spiral soil-squeezing cast-in-place pile construction technology which comprises the following steps: S1, construction preparation: (1) determining the diameter of a pile; (2) setting out of a building; (3) pile position presetting; (4) manufacturing a reinforcement cage; s2, pile driver in-place: (1) pile position deviation; (2) the perpendicularity of the rack is determined; s3, placing the concrete in place; s4, spiral drilling is conducted; s5, cage feeding preparation; s6, concrete is poured, and the drill is lifted; s7, vibration cage sinking; s8, the machine is moved to the next hole position; and S9, finished pile finishing. Pile foundation manufacturing accuracy is improved by determining the pile diameter, building paying-off and pile position presetting, the piling deviation of a drilling machine is limited, strength inspection is conducted on piles after manufacturing, single-pile bearing capacity detection is conducted, bluing rust-proof treatment is conducted on a reinforcement cage through a large oxidation solution pool, and the pile foundation manufacturing precision is improved. And it is guaranteed that the exposed reinforcement cage cannot be rusted in the construction period, the diameter of the pile foundation is determined according to the soil texture, and the size of concrete aggregate particles is controlled.
本发明涉及双螺旋挤土灌注桩技术领域，具体是一种短螺旋挤土灌注桩施工工艺，步骤如下：S1、施工准备：(1)确定桩直径；(2)建筑物放线；(3)桩位预设；(4)钢筋笼制作；S2、打桩机就位：(1)桩位偏差；(2)机架垂直度；S3、混凝土就位；S4、螺旋钻进；S5、下笼准备；S6、灌注砼、提钻；S7、振动沉笼；S8、移机至下一孔位；S9、成桩修整。本发明通过确定桩直径、建筑物放线与桩位预设提高桩基制作的精准度，对钻机的打桩偏差做出限定，且制作后对桩进行强度检验，进行单桩承载力检测，通过大型氧化溶液池对钢筋笼做发蓝防锈处理，保证工期内暴露在外的钢筋笼不会锈蚀，提出根据土质对桩基直径的确定，对混凝土骨料颗粒大小控制。
