Deep soft soil pipe pile construction method
The invention discloses a deep soft soil pipe pile construction method. The deep soft soil pipe pile construction method comprises the following steps that S1, pile making is conducted, specifically, the length of each single-section pile is 8-12m, the inner diameter of a lower-section pile body is larger than the outer diameter of an upper-section pile body, a horizontal bearing platform is arranged on the inner wall of the upper end of each pile body, and an inwards-sunken notch is formed in the upper surface of each bearing platform; S2, pile driving is conducted, specifically, a total station is used for conducting lofting on pile position points, the pile bodies are driven into the designed positions through a pile driver, and if the perpendicularity deviation of the pile bodies is 1% or above, pile driving is conducted after the pile bodies are corrected; and S3, pile splicing is conducted, specifically, the upper-section pile body is hoisted and mounted to the lower-section pile body, a groove platform of the upper-section pile body is inserted into the notch of the lower-section pile body, a cavity is formed between the outer wall of the lower end of the upper-section pile body and the inner wall of the upper end of the lower-section pile body, the upper end of the lower-section pile body and the lower end of the upper-section pile body are connected through a connecting piece, and anti-corrosion slurry is injected. According to the deep soft soil pipe pile construction method, anti-corrosion construction of a connector is achieved.
本发明公开了一种深厚软土管桩施工方法，包括以下步骤：S1、制桩：单节桩长度均为8～12米，且下节桩身内径大于上节桩身外径；所述桩身的上端内壁设置有水平承台，所述承台上表面具有向内凹陷的槽口；S2、打桩：使用全站仪对桩位点放样，通过打桩机将桩身打入设计位置，若桩身垂直度偏差在1％以上，则校正桩身后再进行打桩；S3、接桩：将上节桩身吊装安装至下节桩身，保证上节桩身的槽台插入下节桩身的槽口，上节桩身下端的外壁与下节桩身上端的内壁之间形成一空腔，下节桩身的上端和上节桩身的下端通过连接件衔接，并注入防腐蚀浆料。本发明实现了接头的防腐蚀施工。
