Construction method of static pressure pipe pile
The invention discloses a construction method of a static pressure pipe pile. The method comprises the following steps that (1) in-place is conducted, specifically, pile work equipment is moved, and the pipe pile is positioned on a set pile position or the center of a constructed cement soil pile or the near side of the constructed pile position; (2) pile sinking is conducted, specifically, the pipe pile is directly sunk to the set depth, and if the pipe pile encounters a hard soil layer, the following hole guiding measures are adopted for pile sinking, namely, (1) hole guiding pile sinking isconducted through an external holding pressure pipe pile soil body interaction method, and (2) hole guiding pile sinking is conducted in the external pressure holding pipe pile through an internal spiral soil interaction method; and (3) bottom sealing and chambering are conducted. According to the method, by means of the bottom sealing chambering technology, the problems of the soil plugging effect, the soaking softening effect, the internal corrosion deterioration effect and the post-construction settlement effect are solved, dynamic sounding and light sounding in the exploration process arealso solved, the interactive hole guiding problem in the pile sinking process is also solved, multiple purposes are achieved, the process is controllable, the quality is safe and reliable, exploration and construction are integrated, and the cost performance is good.
本发明公开了一种静压管桩的施工方法，包括下列步骤：（一）就位：移动桩工设备，将管桩就位于设定桩位上或已施工好的水泥土桩中心或已施工好的桩位近侧；（二）沉桩：将管桩直接沉桩至设定深度，如遇硬土层，采用如下引孔措施沉桩：（1）外抱压管桩土体交互法引孔沉桩；（2）外抱压管桩内螺旋土体交互法引孔沉桩：（三）封底、扩孔。本发明通过封底扩孔技术，解决了土塞效应、浸泡软化效应、内腐蚀恶化效应、工后沉降效应，也解决了勘察过程中的动力触探、轻便触探，又解决了沉桩过程中的交互引孔问题，一举多得，流程可控，质量安全可靠，勘察施工一体化，性价比好。
